lag in games - Nexus 10 General

Anyone else notice that gameplay on the Nexus 10 is a tad laggy? I tried playing GTA Vice last night on just 80% resolution and it plays very well and smooth, but the frame rates drop every 10 second to about 5fps for a few seconds, then restores back to smooth gameplay. Similar lag in NFSMW where it lags up every 15 secs. Anyone else experience this on their N10? Perhaps its because of the lack of optimization but then it does run smoothly for a while before the lag kicks in? Anyone has an explanation for ways to fix it?
Tested on both stock kernel and Linaro-based kernel by kToonz

This has been discussed in length many times, the processor is just throttling down

and do you know any way oft fixing it?

As of now you cannot. The closest to it is flashing manta kernel in original development section if you have a custom rom/rooted. He has disabled it personally but wont release that version as of today to the public for fear of people burning up their chips. I actually hope he does anyway as I know how you feel. This device has so much potential and I love it and Im just hoping Google is still optimizing the sh*t out of this device with their next REAL update. (Not that 4.2.1 crap of an update......although needed if you like December)
With their next update I really hope they focus on this throttling aspect of the device and crank up the speed in games as the launcher and overall speed of browsing is the best I've ever experienced with Android as of yet. Did I mention that display is beautiful. (C'mon Voodoo Color and Sound)

Has anybody tried heatsinking the SoC? The Exy5 is a bare chip, so a thermal-conductive pad to attach it to the EMF shield, and a low-profile sink on top of that?

I actually had this idea in mind for a while now... I don't have a suction tool to separate the screen from the backing though :/

I have never thought that Google could release a crap like 4.2.x. Few useless features, terrible battery usage (Nexus 4 is noticeable worse than Opt G http://blog.gsmarena.com/google-nex...-test-see-if-its-better-than-the-galaxy-nexus) and benchmark (actually reviews said that there were some hipcups - the thing you cannot see on Opt G)
Anw, I ordered them (both N4 and N10) coz they are great devices, but still expecting something better than crap 4.2 from Google.

Add: BTW, for chipheads who want to know more about Exy 5 internals, Sammy has a 5MB "user manual" just for you. Sadly it's above my pay grade:
http://www.samsung.com/global/business/semiconductor/product/application/detail?productId=7668
Exy 5 specs specify it coming in two forms: SCP (single-chip packaging) and POP (package-on-package). Both are housed in FCFBGA packaging, which I'm assuming to mean "flip-chip fine ball-grid array".
I perused through this, as unlike your regular CPU w/ a heat dissipator, the packaging is plastic, and I don't know how well it conducts heat. Heat would be conducted through the BGA interface, so you may need to heatsink the underside(?)
Anyway, for hardcore gamers who are (literally) getting throttled, should be worth the hour-long project. Remember to do it while still within your return period.

I have played NFS MW as well as Asphalt 7 and haven't noticed any lags, at least not yet. I read a few posts referencing a background app (Facebook, etc.) causing this issue. Don't know how widespread it is......

Ill try it out and get back to everyone if I can find a good and easy(ish) way to dissemble my device. I would also extend it over the RAM chip next to the CPU too
EDIT. The above picture is actually false. There is a heatsink over the whole area (processor is on the right in this image):
Doesnt look like any TIM though, maybe we could improve temps by putting some thermal interface material in so that better heat transfer happens between the chip and the aluminum plate
I will have to look closely myself, but I may add a very large aluminum plate in anyway. It depends how much clearance I can get away with between the back cover and the rest of the device. I may be able to add in a 1/16" thick plate to just help a bit more with spreading heat and also strength of the device (not that it feels weak to me). This would probably bulge out the back a tiny bit and make the device 1 or 2 mm thicker, and also add a few ounces of weight too. The heat difference might be worth it though

Noticed this as well. Definitely down for trying whatever craziness someone else finds to work.

Tested in ktoonz's kernel in performance mode. Same issue occurred. I would have thought that a custom kernel set in performance mode does not throttle down as badly as the stock kernel?? Correct me if I'm wrong

Definitely not facebooks/auto update issues...I tested it on ParanoidAndroid stock without Facebook app or gmail sync...even tested in airplane mode, yet the result was the same as stock with gmail and notification sync on.

Yep you are wrong
There can be a few things that affect heat output in the kernel at the same core frequency and voltage, but the majority of its power consumption and heat output come from those two main points, voltage and frequency. Even on the custom kernel you are running the same on both, so you will still have throttling problems. And set to performance is making the throttling happen sooner because you are locking the CPU into its maximum voltage and frequency slot with no time to slow down when it doesnt need to run as fast.

Thank you for clearing it up. I read the thread about governors and thought that performance meant CPU is throttled to full clock speed under load

The problem can be solved. check it out

Would turning on Anti-Aliasing work? I don't have my tablet on me at the moment but you can try it. Turn on your developer options if you haven't already (go to settings, go all the way down to about tablet and tap the build number 7 times (after 3 or 4 taps it will say turning on developer options in 4 taps and it counts down). Once its on you can find the developers options on the left. Select that and you should be able to find something that says "Force 4x MSAA" and check it on. Idk if it will do anything though.

Turning on an option to make the GPU work harder seems counter-intuitive to me. But who knows, I suppose anything is possible

Has anyone tested Vice City on the Nexus 10? How's the performance? My brother has it on his iPad 3 and it lags. Wondering if performance on the Nexus 10 is any better.

the N10 is not optimized for its screen resolution
simple as that.
that is with constant low fps as it seems to be for many games.

Prime C3 Model Testing

Just got my 3rd Prime and this would be my second C3 (first I had was C1)
Thankfully there is no lightbleeding and no dead pixels or white-freaking spots.
Wifi is just like before, I haven't tested it from a far distance yet.
Inside I get 65Mbps
GPS is crap as usual, in my balcony it finds 1 satellite but does not lock.
Will try more outside later.
Camera has been good pretty much from the beginning but i feel it could be improved.
I like that you can zoom in 1080p now.
Have had the unit for about 48 hours and it has rebooted 3 times.
Was so ****ing stupid that I did not root before the latest OTA .21
All in all it feels pretty solid and the Prime is awesome, I hope Asus will eventually release firmwares that make full use of the CPU's Full Potential.
Browser is OK, but it crashes every now and then but you can resume your previous windows so that's cool I don'http://forum.xda-developers.com/attachment.php?attachmentid=986740&stc=1&d=1333731891t remember this existing before .21
OkI! Just sharing!
Edit: Speed test via Prime,
Edit: April 6, Testing.
Information about Battery Life so far with the C3:
At the moment my battery stats are 19 hours and 11 minutes, and battery time left is 57% (See Image).
My image settings has been at around 70% with IPS+ on sometimes on and off, maybe 20% of the time.
I have downloaded heavy files maybe 3,4 or four of them.
I've watched HD youtube flicks, transfered files to ext.HDD, taken pictures and experimented with the camera functions.
I've done ALOT of surfing.
I have also downloaded and deleted apps, tested Shadowgun, and some other games.
I have skyped quite a bit, I have filmed as well.
I've tried the HDMI out connection.
I have sent and received many emails.
I've switched from Normal to Performance mode many time for testing and for faster browsing or general speed But honestly I dont see much differene). NEED TO ROOT!!!
I have done a lot and am happy with the performance (although it ca be tweaked and the the battery will last less but I don't really care to surf or use my machine for than 5 hours at a time.
My prime has been connected with the Dock but not constantly, I took the Surfpad off the dock at least 4 times.
Im pretty happy so far with my Pime and I am not rooted and running .21
EDIT: I am still not done and the battery is at 35% and i've sending images via dropbox and other ****.

Information about Wi-Fi range so far with the C3:
Wifi is not bad and I have never experienced much problems with it but I decided to do a test anyways, in the picture below you can see a building in which I live on the third floor, and I took it from the ground just outside of the building door entrance. And the wifi was not strong at all haha as you can see in the picture but I was connected and was pretty stable.
Distance I would have to be in meters is maybe 8 or 10 meters?
That in Feet is 26 or 32 feet.
Building is concrete.
GPS Info:
While I was outside I thought why not test the GPS while im there, so I tested and I WAS F-ING suprised!
At first the GPS Status tool started showing 3 Satellites (no biggie i thought).
So at first it was showing 3, then 7 then a fix and then more, see images.
FIX!
Good Fix!
And more!
First Fix with Wi-Fi OFF
And some more after that, I ran around abit (my neighbours probably thought I was insane LOL) to see how stable the signal was once fixed, these are images taken while lightly running around:
Well I hope this info helps, its seems the Prime is perhaps underestimated?
Also, I am still using it Will take one last snapshot before the battery dies
Some comments on the hardware externally, the dock buttons feels different from the first and second Prime this one the C3 has more smooth button material, the other ones were more rubbery (Which I thought was better). It could be my imagination.
Then there is the backplate, the first one had a more 'flat' surface somewhat similar to the iPad, the second was slightly less 'flat' but on this Prime the backplate is more curved (Again I could be imagining this but I doubt it), there is not 'flat' square in the overall shape that I remember from the first the C1 model.
Any comments are welcomed and I hope this info helped.
Cheers!

Do you have a pair of Bluetooth headphones? Stream a movie with Diceplayer .mkv and sync headphones with your bluetooth. See if audio is in sync on the .mkv movies thru the bluetooth headphones. Mine is working fine for the C2 prime i have. But, some say that even with the new CX models they are still having the Bluetooth fallout issue.
Thanks!
Not sure I do, I rarely ever use bluetooth earphone.
I will see if I can test it and come back with the results.
Cheers
After 1 month exactly of asus having my rma, they finally shipped me a new one last night. It too shows the c3 serial, so I'm prayin!!

How the HELL do I attach images to the post I mean for example under a text. not via URL.
How is the color temperature of your screen? I got a C2 from BestBuy and a C3 from Amazon.com. The C2 is slightly blueish and the C3 is yellowish. I pre-ordered another from Amazon hoping to get another C3 with a better screen, but was curious how your C3's screen is.

Color is fine, I've never given it any thought, I only know that sometimes the screen is bright sometimes after watching a movie, but I noticed that if I go back to player used and turn the brightness down the 'colors' are more vivid and not overly bright.
Could be a SW problem, I know that my last 2 units had this issue.

How heavy is the lightbleed?
You have a right to return if you have it in general, but if its alot and bright then you can surely get a new one.
I'm sure the C4 will be interesting, I might change because I still have lightbleeding even though everything is fine, you have to get the most of your money and this machine is not ridiculously cheap.
Maybe those C4's will be better or maybe even C5 by now.

well , it's not heavy yet, but it wasn't there in the beggining i guess. i only notice it when using black background or app with dark coloured theme, which is to say i prefer dark desktops/homescreens/apps. it's becoming more and more noticeable. i have no complains on mine, other that wifi could be just a bit better and this light bleed. my fear is that it will only get worse, like i've seen people describe around here.
i would like to get a newer model, sure, i'll just explain the situation to the store where i bought it. got it the 23rd march. maybe RMA works, who knows, might get lucky.

I think there are C4's out now so when you talk to your shop of purchase, TELL them that you would like a C4, I am on my 3rd Prime and main reason I returned the previous 2 was because of whitee spots,dead pixels and heavy lightbleeding.

Asus Transformer Prime TF201 review!

After having the Prime for slightly over two weeks, I can give you my first impressions, review, and overview of this hyped up tablet. I must say, finding one of these really was hell for me. It took me almost 3 months for a local shop to get stock for reasons unknown. And oh, I'll also be doing a slight comparison between the Prime and the iPad(chill iPad and Android fan boys). Now I must apologize if this is a rather long winded. I'm no professional reviewer. I'm just here to voice out how I feel and to help whoever that is deciding whether or not to buy this tablet. If you disagree with me, it's alright.
First Impressions
Screen
One of the the concerns I had for the tablet was the screen. You might wondering, why I had this concern. After using a Galaxy Note, I was accustomed to the really vibrant and saturated screen known as Super AMOLED. And I had quite a hard time deciding between this or the next Samsung Galaxy tablet(probably a successor to the Galaxy Tab 10.1?). But in the end, I chose this over the latter. I'm glad to say that the screen is actually quite okay. You won't get the crazy saturation and vibrance levels of any Super AMOLED screen, but instead you'll get natural and frankly quite vibrant colours. If you already have or used an iPhone, this screen should be quite similar other than the high pixel density. Talking about pixel density, when I first looked at the screen, I could(almost) see the individual pixels. Uh oh. As I used it, I sort of got used to it. I often wondered why Asus couldn't have used a higher pixel density especially because it's a 10.1 inch screen we're talking about. Visibility under sunlight is rather; disappointing. You can try using Asus's 'Super IPS+ mode' for outdoor viewing but it only makes it slightly more visible. I'm not sure whether Super AMOLED Plus suffers from this too so I can't say much about it. Compared to the Prime, iPad 3's retina display isn't as sharp as I thought it would be. It could be due to the matte screen protector that I applied on it, but the same screen protector on my iPod 4th gen. still looks sharper and more crisp.
Performance
I'll give you a head's up whoever that is not so familiar with the specs of the Prime - it's running on an Nvidia Tegra 3 Quad Core processor chip clocked at 1.4GHz(yes, you read that correctly), a more than sufficient 1GB of RAM and a choice of 32GB or 64GB of storage space expendable up to 128GB with an SD card. Oh, and it comes with a keyboard dock as well. Seeing all those specs, it's definitely an iPad killer, right? No, not really. Until apps and the right software comes, it'll perform like any other dual-core tablet. What a shame. And that's what I felt when I first used it. Ice Cream Sandwich, Google's latest Android operating system performed rather well. I'll be honest and say, that everything wasn't exactly snappy. Even when set to 'Performance mode', the browser crashed every now and then. I downloaded and used Dolphin Browser HD too, same thing happened. I actually came to a point of thinking of selling it for something else since I was so disappointed. I tried searching for solutions and ended up doing a cold boot. That partly solved the performance issues. I guess I'll just have to wait until the next update. Until that update comes or I just feel like flashing a ROM on this, iPad just seems like a faster tablet to me even though it's only the GPU that is quad core.
Battery Life
Advertised of having 18 hours of battery life docked to the keyboard, battery life isn't exactly as impressive as I thought it would be. First off, after using the tablet for internet browsing, Facebook, Instagram checking every now and then for a mere hour and a half, the tablet consumed almost 70% of the tablet's battery. But after using it for a couple of days, it improved significantly. Last night I tested Asphalt 6 for about an hour plus, the battery went down by 18%. As I'm typing this review from my Prime, it has drained about a good 35% in an hour and a half. After reading several forums, I'm pretty sure it's because of the latest update by Asus that caused this, not the tablet itself. iPad has a similar battery consumption rate.
Apps
As we all know, Apple's App Store was the king of all application stores/markets when compared to Google's Play Market(formerly called Android Market) when it started. As of now, the tables have turned. Day by day, I see the number of apps and games for Android tablets increasing steadily. Of course, some might think generally Apple's apps are more robust and premium. And while that is true, I also personally think that Android developers improve over time and learn from mistakes. Comparing the preinstalled applications, I say Android owns the YouTube app hands down. But when comparing browsers, I think Apple's Safari has a slight edge when it comes to the looks and feel of both browsers. Generally, I'd say Google's Apps like GMail, YouTube and Google Play are better on Android.
Overview
I think this is a great tablet despite the flaws I mentioned. It's all just a matter of getting used to. Battery life, the bloat ware and performance issues can be taken care of with future updates or flashing a custom ROM. As for the speakers, investing in a pair of compact speakers or headphones will take care of that. The keyboard dock feature is actually one of the main reasons for getting this tablet. And support for mice and flash drives mean this might be a replacement for your Windows device. Of course, not everything can be done on it but for casual users this is more than sufficient to take care of your browsing, gaming and socializing needs.
And oh, the comparison with the iPad 3. I would say they both have their own flaws. The more apparent question you should ask yourself is not the specs of the tablet, but the operating system they are running on. Is it the open source that Android offers? Or is it the closed, but simpler, but more refined that Apple offers?
Pros
killer hardware
Ice Cream Sandwich
comes with a keyboard dock
good viewing angles
able to hook up a mouse and external flash drives and hard disks! Solves my problems with a tablet
SD card and micro SD card slots
HDMI ports
Cons
battery life
surprisingly sluggish despite hardware
weak speakers
ergonomics were a little weird at first
quad core doesn't really mean a thing until apps support it.
has a fair bit of bloat ware

Twice you stated that the Prime comes with a keyboard dock. That's not true. The keyboard dock is a separate purchase. Also you are a little late to the party. There are thousands of reviews and opinions concerning the Prime. I've had mine since December 20th.

yeah no offense to the OP but this review is about 4-5 months late
I don't share your preference, but it's precisely that, a personal preference.
On the Apps section, you barely scratched the surface. Sheer quantity of apps not a useful measure. Also, have you seen the Overskreen Browser or Stick It! ? The iPad apps are not necessarily more robust, nor are they necessarily premium. They just cost more (considerably in some cases for the same app on both platforms). What about Amazon's Android app store? They give away a free app every day (some are crap, some are not).
There's a pretty significant difference in cost between the two, relative to what you get. The TP is simply more bang for the buck. Apple likes to sell a Toyota for the price of a Lexus and make you think it's a Ferarri. Any shortcoming is the fault of the reviewer, not the product (you're holding the phone wrong).
Your battery life sounds terrible.... where is your brightness and Super IPS+ on?
And for visibility in the sun, I never had a problem and I've tried to sit in the brightest areas to see how much the IPS affects visibility and it does a pretty good job.
I can't say I aggree with your review really, your issues and critizism just sounds a bit far fetched to me. Your pros kept mentioning features found on the keyboard doc not the tablet. SD card slot, attachable to HDDs, mouse, flashdrives, require USB slots which is on the keyboard.
A review of a tablet, but giving 50% of the pros to just the attachment, Kind of wrong don't you think?
Wow, a lot of negative comments. I thought it was a nice review. If you already own the device and you're not interested in the comments of a new owner...don't read the thread.

It's part of building concensus. His review was fine. Better than most, but he opened himself up for ridicule with his unsupported statements about the apps and the app store. Twice, bloatware was mentioned, yet no detail of what this bloatware is. I don't recall seeing AOL, Compuserve, nag-ware Anti-virus trials, or 90-trial versions of productivity apps installed on my TP when I got it.
Many are interested in the comments of a new user, but few will take a Mulligan when it comes to inaccuracies or other unsubstantiated criticism.
Great review...Looking forward to your next review on the Motorola Xoom!!
Just messing with you man, but yes you are just a little late.
I question your battery life results.
An hour and a half of web browsing, Facebook & Istagram shouldn't use up 70% of your battery, especially if you are using the Prime with it's keyboard dock.
Even if you had the brightness turned all the way up, IPS+ turned on and were running on High Performance mode, I don't think it is possible to use up 70% of the Prime's battery in 90 minutes with the usage you described.
I have played highly demanding games like Dead Space, Dark Meadow and Modern Combat 3 for 2-3 hours in a row on my own Prime and I almost always have slightly less than half of the Prime's (tablet only) battery remaining when I stop playing.
When doing light stuff like web browsing an Instagram for a few hours a day, it is common for me to go two or 3 days between charging.

An hour and a half of web browsing, Facebook & Istagram shouldn't use up 70% of your battery, especially if you are using the Prime with it's keyboard dock.
Even if you had the brightness turned all the way up, IPS+ turned on and were running on High Performance mode, I don't think it is possible to use up 70% of the Prime's battery in 90 minutes with the usage you described.
I have played highly demanding games like Dead Space, Dark Meadow and Modern Combat 3 for 2-3 hours in a row on my own Prime and I almost always have slightly less than half of the Prime's (tablet only) battery remaining when I stop playing.
When doing light stuff like web browsing an Instagram for a few hours a day, it is common for me to go two or 3 days between charging.

When I had my Prime, I tracked battery life pretty closely. I've posted about it elsewhere on this forum, but basically my battery life was about like this (balanced mode, screen brightness about 30%, non-IPS+ mode):
1. Video: Prime was great here, burning about 7%/hour. I think the 5th core was being used exclusively for Netflix, etc.
2. Ebook reading, email, etc: use was about 10%/hour.
3. Browsing: for some reason, browsing was a little more battery-intensive, at about 15%/hour. This included any app that used the browser engine, like RSS readers.
4. Gaming: heavy gaming burned between 20-30%/hour.
So, even with intense gaming, the Prime should last at least 3.5 hours. And, I'd have considered that decent enough, all considering. Toss it in the dock, and you could game for over 5 hours.

browsing will always be a heavy battery burner on prime. with or without flash on. same goes for my Ipad. web browsing is very RAM intensive. it can burn up alot of ram fast. so therefore its going to burn battery at a faster rate. now ddr3 ram would probably make web browsing burn up less battery since its more energy/power efficient. but even web browsing on my Ipad burns battery faster.
As for the op battery claims, it seems way off to me. never heard of battery burning up that fast with the little bit he said he did.
Battery is something I dont even worry about on the Prime. Asus got the battery department right

Here's a fast and dirty for anyone looking at a prime :
For the love of GOD, wait until they release the .25 update. Staying stock on .21 is just asking for suffering. The bloat is there, no doubt, mostly from ASUS putting it's own widgets in - a task killer sounds like a nice plan until you find out it's more likely to CAUSE problems than it solves.
Right now there's definitely something up with the way the kernel interfaces with the Teg 3 chipset, the .25 update apparently will cure this, which will in turn result in better stocklike releases and some inlining of new kernels for the AOSP crowd.
If you're okay with toasting the warranty, there's budding dev support, and there's some genuinely good reworks of Stock available, or for those looking for the pure AOSP experience, there's more than enough excellent choices to cover you.
It's a genuinely excellent tablet, but ASUS, no offence, but you need to make with the chop chop on getting this tablet up to full speed. B- for your software, when even single developers with some time, motivation and a working build environ can outdo what you supply.
There, by now everything else that IS worth discussing regards hardware and the android ecosystem has been covered, what I've given is a quick skinny as to the Prime's current position.

Now you see that all depends on having a narrow world view and continuing the belief that the only country in the world is the USA. There are some global territories where the only option is with a dock. Like the UK for example.
Apologies, and a little more elaboration.
My apologies to everyone for doing this review so late. I'm pretty sure many of you have already gotten it. But there are friends of mine who haven't, and are still deciding. Once again, I'm no pro in this so I'll take any criticism as lessons. I'm just letting people know how I felt of this tablet. Yes, of course, I've listed many pros of the keyboard, because it's one of the main reasons why I got it. I'm pretty sure you already know that it has the killer hardware etc. but that doesn't mean everything. Usability, is. As far as I know, trying to play a movie when I was in the car was rather uneasy. I could see the movie, but it's rather unadvisable if you'd ask me. I am not sure whether my copy is faulty or whatsoever, but I hope not. I just find it kind of ridiculous that even though I purchased a high end tablet, there's still tweaking to do to make it perform as it should. I will follow up a more complete continuation of the review in the near future. To whoever that disagrees with me; you're entitled to your opinions and so am I. I find it ironic whenever some argument happens because of something so small like this. As f now, until another update becomes available or I flash a custom ROM on this, I'm not 100% satisfied with this tablet.

It is. It came with the dock for me. Yeah, already noted. The whole point of this review is not for the already existing owners of this tablet, but for the ones for who are deciding.

Hmm, I'll get back to you on the battery life. Maybe it just needs time until the battery will learn my usage like some reviews I've read from others. But I do notice that whenever browsing takes place, the draining becomes worse. Gaming now seems fine, and I think it'll last for about 4 hours? I've also read there has been some complaints about the latest update .21 bringing battery drain when using WiFi. Oh, and btw it's 70% drained from the keyboard's battery, not the tablet's.
Nice review!
Hopefully the next update will fix the sluggish performance and improve battery life.

[Q] Samsung Galaxy S3 heat issues

Hey guys. I bought my first smartphone a month ago which was a sensation xe. I had to return it multiple times as it got way too hot. I just purchased a Galaxy S3 and I was wondering if the the warmth it emits is normal. I am experiencing temperatures from 35-40 while browsing the net and temperatures from 38-44 while playing graphic intensive games like Riptide. I was wondering if these temperatures are in the normal range. It gets pretty warm but not super hot. I am not tech savvy like most of the members here so I have no idea about ROM's or underclocking. Is my S3 normal or am I just overreacting because of my bad experience with the Sensation?

It'll get warm when you play demanding games (or rather, high-end considering nothing is demanding to this phone ). This is coming from a former S2 and Galaxy Nexus owner. It's because it's plastic.
what app do u use to see the temperatures?
Thanks Product F(RED). Do you own an S3? Do you see similiar temperatures? Do you think temperatures in the high thirties are okay for just browsing?
And to see the temperatures download an app the tests for battery temperature. Just go to the play store.

Yeah, I have the international in 16GB, Marble White. The only complaint I have about this phone is the camera sucks balls compared to the S2. Seriously, there are no details in the pictures. But back to your issue, it'll get warm if I play Shadowgun or GTA III. Not HOT, but warm.
Playing gta3 or nova3 or any other high demanding game will push it up to not much past 40c, I mean actual temperature of the device, not sensor values. This kind of temperature is expected from high demand apps and is not unique to the sgs3. The plastic casing probably doesn't help much either (metal would sink the heat and disapate quicker).
Even if you got it up to 50c then it would still be safe, maybe uncomfortable to hold but safe.
The device that 'exploded' that everyone is getting worked up about probably has the in car charger to blame. The cheaper ones aren't usually protected from surges, or the curent isn't regulated as well as better ones.

That's because the Wifi antenna is sending and receiving a constant stream of data and the CPU and screen are working their asses off to run your game (the screen can get very warm).
Bottom line is, the phone might get very warm, but it shouldn't be scolding hot.
So basically I have nothing to worry about? I understand it getting that warm while playing games but it is normal for my phone to get this warm while browsing? As I am talking to you guys now my phone has been hovering between 36 and 40 degrees.. I mean its warm but not uncomfortably so. Thanks for helping out you guys are awesome. On a side note how did you find gta3 I looked on game hub and the play store but no luck
I don't know about others, but I have the nvidia drivers installed via Chainfire3D and the market fixed to allow tegra games.

Probably not available in your country if you're not in the US.
Same here, got it on the longest day deals ( search for it in the play store) For 1$ using the chain fire market fix.
About the heat, yes its normal, while browsing the phone can get quite warm, guess the quad core is to blame here

Hey guys I'm back. I was wondering about underclocking or rom. I am pretty tech-illiterate so I dont know what this all means. But basically I am wondering if this will make my phone run cooler? If I do this does it void my warranty? Is there any way a newbie like myself could do it?
thanks!
i've bever gone over 43-45c by using shiya kernel. Im keeping the cpu at 800mhz when gpu clocks are at max. I dont have any lagg even if i cap the cpu to the shiya default 500mhz but yea... before when the cpu was running at 1200mhz as samsung default and gpu at max also my device got really hot :/ i'd call it desing flaw..

Is that possibly related to a sharpness setting buried somewhere, perhaps? I've seen a similar comment about fewer details on some reviews, but they noted that the overall pictures still looked very good.

How do I get these kernels? Like I said I am new to all this and I really don't understand how to do it or even the pros and cons of customizing things like that. I mean didn't we buy this phone because it's so fast? Why slow it down? Does it really make a big difference in the heat or battery life? And most Importantly does it void your warranty? Excuse my ignorance on these matters and thanks for you help

Curiously, the camera recording at 1080p gets a LOT of detail, what the photo quality SHOULD be like. So I'm thinking and praying this is a software issue because this is going to be the phone I talk on vacation.
Those S2 pictures do have rather impressive detail at full size.
The samples you showed all seem to be 72dpi, but different sizes per phone (i.e., the S2 shots are markedly bigger) - would be nice to compare shots from both phones with same photo settings and subject.

[Guide][Hard Mod][Nexus 6P]Improve cooling and greatly reduce Thermal Throttling

Warning: This MOD will void your warranty. You will have to open the device and leave traces behind by performing it. Only perform this Mod if you are willing to take a risk.
Since I have already voided my warranty of both my Nexus 5 (2013) and Nexus 7 (2013), why not do it again? There are a few things I do not like about the Nexus 6P and having looked at some pictures from various Teardowns, I was pretty confident that I could improve this device as well. Be warned that this device is really hard to open and I had a few failed attempts before.
What can you expect from this MOD? A more reliable device, better cooling and less Thermal Throttling.
I want to thank Aquatuning Germany for helping me out with this guide by sending me this nice thermal paste as well as the required Heat Gun I was lacking.

Phobya NanoGrease Extreme: This thermal paste has a insane thermal conductivity of 16W/mK which promises excellent results and will replace the pink rubber used by Huawei.
I tried to open the Nexus 6P before but failed miserably with a regular hair dryer. It seems that you need plenty of heat and the right tools in order to open such a device. I have never needed a Heat Gun before but everybody has to start somewhere
Alphacool HardTube Heat Gun Pro 2000W: This Heat Gun has 3 different levels of heat: 100°C - 450°C - 600°C and can burn a hole in your hand if you´re not careful.
I was afraid at first because the visor glass is very thin, curved and looks like something which will break just by staring evil at it. If you really think you have what it takes to torture your device, let´s proceed!
Material needed:
- a Heat Gun
- rubbing alcohol
- a razor blade or parts from a soda can
- a precision screwdriver set
- premium thermal paste
- premium 0.5mm thick thermal pads
- a guitar pick or spudger
- a very thin guitar pick or chirurgical knife
- some thin plastic card
You might also consider to get some sort of basic repair kits for mobile devices if you´re not confident that the tools mentioned by me are enough for you to perform this MOD too.
This video inspired me to give it a try too. I think this one is a nice example and since it helped me to finally give it a shot, I guess it is worth mentioning.
https://www.youtube.com/watch?v=PdWR7cU0sdc
You need to open your device and to make sure that you lay down your display on a soft surface in order to prevent it from being scratched. Don´t forget to remove the SIM card tray right after.
Use a Heat Gun to soften the glue and carefully insert a very thin razor blade between the visor glass and the Aluminum case. It is a great idea to raise the phone from your table by using some spare piece of wood or else you might heat it up too. Be warned that you might need several tries before you can cut through with a thin razor blade or some self made blades out of a soda can if you are not a experienced phone technician who does this kind of stuff on a daily basis. I tried at first the 100°C setting but this one took too long. I switched over to the 450°C setting and kept a good distance because there is a high risk of damaging the components or even igniting stuff.
Finally, I removed the critical visor glass without shattering it. This is really scary if you have never done anything like this before.
Use a Heat Gun for the lower plastic part but be careful because this part does not like heat at all and might warp and change the colour. You really need to be patient on this part. Fitting a razor blade works too but it is not as easy as you might think. Once you have built a lever and raised one lip, everything is pretty easy. Use a thin plastic card or similar object to cut through.
Now you need to remove all 6 screws with a precision screwdriver set and make sure that you don´t lose them. Removing the back was quite tricky if you lack the tools. I had to borrow a very thin guitar pick made of metal in order to open the case.
Remove the screws of the motherboard and disconnect all connectors. It is easier to remove the motherboard if you remove the 3.5mm headphone jack and front camera first. Now you will see the rubbery thermal paste used by Huawei. It looks cheap and also feels cheap. I bet it is not the highest grade paste used either!
I put the motherboard on a antistatic foam and had a closer look.
Use rubbing alcohol and some cue tips for ears, paper towels or even toilet paper in order to get rid of the old thermal paste. This looks a lot better, eh?
Clean the closed container with rubbing alcohol too.
What is inside? More of that lovely thermal paste. In order to open the lid you need to use a lever. Make sure that you do not use much force and especially damage the small components around. It is not very hard to open the lid once you have figured it out
The back of the lid also needs some cleaning too.
That looks a lot better. Use rubbing alcohol again and clean the SoC and the back of the lid.
Alphacool Eisschicht: These pads have a insane thermal conductivity of 17W/mK which promises excellent results. I´ve used them in my Nexus 5 (2013) Mod too since these 2 stripes are enough for many modifications.
Attach the thermal pad you want to use. You will need about 15x15x0.5mm in order to fully cover the SoC. Make sure to attach the pad in such a way that you can still close the lid later. The SoC is a really tight fit but it seems that such a pad might work out too if it can adapt to the gap without high pressure. At first I used the Phobya NanoGrease Extreme thermal paste I received. This paste reminds me of Arctic Silver 5 and it is not very easy to apply. It is quite thick and needs some patience. You can use thermal paste instead of a thermal pad too but it´s up to you to decide, how much you need in order to fill the gap which is quite noticeable.
Apply the thermal paste on the metal area too, make sure that you do not use too much of it. Let some space for the metal contacts to touch the area too. It does not look too good but once you attach the motherboard back, it will fit like a charm and adjust itself to the existing structure. Use a thick "drop" of paste and let the lid of the EMI shield spread the paste for you.
Now reassemble the device. You can use the old glue of the visor glass and lower plastic part and it will still fit. I might buy some thin double sided adhesive bands later and fix these parts again. At least now I will not need to apply that much heat again in order to remove them
There was a huge discussion about how much thermal paste I´ve used and in order to avoid it. I´ve performed this Mod 2x now and there is barely any difference noticeable between the first and the second try. The thermal paste between the SoC is a lot dirtier while a thermal pad does not create that much mess.
Update 29 February:
Like I said before, I´ve performed this Mod twice and there is barely any difference noticeable between using a pad or using thermal paste. I get slightly better scores in Benchmarks now but in the end I should have let the device like it was after the first try.
Here is a nice picture for you. This is how the area looked after I removed the motherboard again. I simply used a larger surface of the lid to connect with the metal area which wasn´t a issue after all. Did I flood the whole device with thermal paste? Did it change the thermal conductivity for the worse? Absolutely no.
And now some of you might wonder, what happened to the SoC first? Was this one drowned in thermal paste too? Well, just have a look at this picture too after I scraped off the thermal paste. As you can see, there was barely any "mess" at all or else it would have looked a lot worse. The "grey" layer is tough to remove though but it does not matter in the end since you cannot reach some pores with a paper towel. It won´t affect the thermal conductivity of the now attached thermal pad.
There was nothing wrong with the modification itself, I simply wasted more material than necessary.
The whole device runs smoother and feels warm and nice after a while. The display remains warm too and also the Aluminum back needs a while to heat up. Sooner or later this device will throttle too but it will take a lot longer before it heats up enough because the heat is dissipated faster through the elite thermal pad and thermal paste. I´ve played again with various benchmarks and the high scores and linear temperature increase are evidence enough for me that the cooling is great the way it is now.
Update 27 February:
Many guys have mentioned that I used way too much thermal paste. I might have used a lot more than necessary which is quite a waste but it doesn´t flood the entire case and spills out of every corner. You can use a lot less paste or even try a small metal plate (about 0.3mm - 0.5mm thickness) if you have the patience to measure the actual gap between the EMI shield lid and the metal area on the display frame.
I´ve tortured this device a lot and can confirm that the heat dissipation is still a lot better than it was before. I might open this device at a later time again and see if I really made a mess and also provide you with pictures.
I don´t force any of you to modify your device but you´re free to tell me your experiences in case that you actually performed this Mod too
I just wanted to show you my Mod and also inspire some of you who also like to perform crazy experiments. This was the main reason why I went through the trouble of creating this guide.
Tests:
Update 10 March:
RngrYogi was brave enough to perform this Mod too and used nearly the same ingredients (similar thermal paste and thermal pads) like I did. Check out what he has to say about his results. He can confirm that the Mod helps the device to lower the thermal throttling intervals and to recover faster His Benchmark results also show that this phone can deliver a great performance when it doesn´t heat up too often.
I will update the OP from time to time if I get more success stories like these.
Update 28 February:
How reliable are Benchmarks when it comes to testing for stability or performance? Even if you perform 100 runs, you have a high tolerance between the results you get. All I was interested in was the temperature increase which is shown in some Benchmarks. It´s linear which is a good sign that everything worked out fine, even if I used a lot of thermal paste to fill the major gaps. That´s enough evidence for me that the cooling of the SoC works like intended and didn´t change for the worse.
On the other hand, if this Mod would have decreased the cooling performance of this device, the scores should also be way lower? Simple logic because a hotter phone tends to throttle more often than a device with a better cooling.
How did I test?
I use a customized, rooted and debloated Stock based ROM (MMB29Q) which suits me well. Every system is different and it also depends which kind of Apps you use. I used two different ways of stressing the whole system by forcing the CPU to use the max. speed at any times in order to generate as much heat as possible. The right tool for me was the usage of the ElementalX Kernel and the EX Kernel Manager App by flar2.
1)Stock Speed, no overclocking at all: Performance Mode activated and Min=Max frequency enabled for all cores.
2)Max Speed, set highest overclocking settings of the Kernel: Performance Mode activated and Min=Max frequency enabled for all cores (1708Mhz and 2054Mhz)
I also killed all active Apps like eg. WhatsApp and let the device stay idle for a while before performing the Benchmarks. Like I said before, there is no way to ever get the same results because every device has a different configuration and amount of Apps installed. The used Kernel settings can also influence the performance.
Here is a great example of how unreliable Benchmarks are when it comes to comparing the performance. I don´t want to link huge image files directly in this OP, this is why I post external links this time. If you don´t trust me, see for yourselves that both images are 100% unaltered.
27 February, Antutu 6.0.1 @ maximum overclocked speed: I was offered a update yesterday but only received a parsing error when I wanted to install it. Have a look at the Playstore ratings and see for yourselves, this is why I could only use 6.0.1
http://abload.de/img/screenshot_20160227-1lirkv.png
28 February, Antutu 6.0.4 @ maximum overclocked speed: This time I was able to install the update and perform the test under the same conditions like yesterday since I didn´t change anything again.
http://abload.de/img/screenshot_20160228-1frrar.png
You get a different result for many reasons. I guess I made my points clear why I don´t really trust Benchmarks when it comes to comparing scores only? I trust my user experience instead. If the device performs well, Apps open fast and I don´t feel any lagging at all, I don´t care if one Benchmark would show me 100k points or even 40k points.
In the end I want to make clear that this modified device will also throttle sooner or later when the device heats up after a while which is inevitable, even if you use the best thermal paste available. The cooling system of this phone is physically limited. Even if you use a diamond sheet instead of thermal paste, this device will still heat up at some point. It would also take a longer time.
This MOD can prolong the time needed for the Thermal Throttling to kick in because it helps to dissipate the heat faster. If you play heavy games or use the phone for Benchmarks only, you might notice the Thermal Throttling to kick in after eg. 2 hours instead of 1.5 hours.
I also made a full NANDroid Backup in TWRP which included all partitions and also enabled compression. The phone heated up like you are already used too but it was not as hot as before. It felt a lot cooler.
I am happy with the results, in terms of reliability this is a great improvement for me At least now I know what I have inside and for me it was worth it.
I feel honored that this Guide has been mentioned at XDA in this article and also in the video.
Impressive efforts to open the phone. How do you go about sealing it back up when you are finished?

Using a heating gun to re-melt the adhesives to make it sticky again. Buying thermal paste for a phone that is so difficult to take apart (2/10 repairability score on ifixit) is a complete waste of time/money/effort. If someone does this, they will see little, if any, noticeable gains where it effects the way they use the phone, and they will have severely weakend the bonding strength of the adhesives in the process. Not to mention the numerous ways of messing up the disassembly/reassmbly and resulting in a brick. And now since the warranty is now voided, they have to buy a whole new phone at full price to replace the one they just turned into a paper weight..
It's just asking for trouble and definitely not worth it. Tons of risk for little gain.
OP - that is way, way too much thermal paste. Even if you were to only apply it just to the CPU like your pic above, it would have been too much - yet, you double downed by applying just as much on the heat shield as well...
Chances are if you were to take it out again, it would have gotten everywhere by now. I wouldn't be surprised if it started leaking out at one point.
I ended up doing kinda of the same thing on my M9, except i used thermal paste under the metal rf/heat shield, then i had a couple xbox 360 motherboards laying around, and instead of using thermal paste from the heat shield to the metal casing i used a thermal pad, i cut it in half to make it thinner and reassembled without creating a mess. and no bulges during reassembly.....
just my experience

Yep, definitely too much. For a CPU that size, something like a grain of rice should be enough.
Way too much paste. Also, spreading it around like that creates air pockets which are a no-go. Not a huge deal for this little processor, but still something to note. Also, toilet paper? Hell no - at LEAST use some high quality paper towels. Toilet paper would make a mess and fall apart.
Good on you for being brave and trying it. Some real tests would've been cool to see how much of a difference was truly made though!
Way too much paste. The paste is a lot less conductive than the metal. A LOT. You only want it to fill the air gaps which is way more insulating. Hopefully it works out for you
OK, I might have gotten over the edge with the thermal paste and I see that in case I would want to remove the motherboard again, it would be a lot harder now. This kind of thermal paste is also quite sticky.
I've created the guide to show you what would be possible to achieve with this phone, in case you like stuff like this.
However, like I mentioned in the OP, this modification is very hard to perform since opening the device involves many risks.
I like experimenting though and if my Nexus 6P should fail, I'm out of luck.
I also have my doubts that most guys would want to perform this Mod too but what if someday the battery fails and needs to be replaced? You would have to open the device anyway and also use the chance to apply fresh and better thermal paste
with that amount of TP it's gonna heat up even faster and in a few days you'll be left with a hardened up layer that doesn't conduct heat
I was thinking to get another plate of copper, if there is a gap,or some thermal pads, not alot you can do, better to have an efficient SOC or implement a better way to get the whole phone to absorb the heat.
As above, alot of thermal paste, a small dot would be better as you used a better paste than stock,
Anyway it's silly to think we should have to do this,
OP, thermal paste is not the same as icing on a cake. You don't try and layer the CPU in it.
WAY to much paste .......
Yeah...... No thanks
Thanks for all the Feedback. I´ve updated the OP I don´t force any of you to perform this Mod and I will use less thermal paste next time For now, everything is still OK and I didn´t see any thermal paste leaking through the motherboard and the whole case. I got over excited and used more paste than really necessary which is a waste of material but didn´t change the results for the worse.
I´m performing a series of extra Tests which will also include a overclocked device in order to see if I can somehow teach this guy the "Art of Heating" again and trying to burn my fingers.
Just asking if this would work on other devices?
It should work on other devices too because many of them are built in a similar way. Other devices might be easier to open though, like it was the case with my Nexus 5 (2013) and Nexus 7 (2013)

I hope so because some devices do not even have thermal paste/ whatever it is on their CPU and the CPU is usually soldered and tightened down.
It depends, the SoC of the Nexus 7 (2013) faces towards the back and not the display frame. A slight improvement is still possible because you can use a thin metal plate or a thermal pad to connect it with the lid of the EMI shield. It´s better than nothing.
Even if you manage to find a gap inside the case and to glue a thin plate of metal to eg. the back and connect the SoC with it, it will be a great improvement. This kind of ICs can perform very well, even without a passive cooler attached to them.
What I noticed now is that my battery temperature is lower because it gets less heat from the SoC now. The heat is dissipated faster through the better thermal paste. I will post a few Screenshots later and also describe the measuring conditions used by me
How did I get here?
Oh yeah, WAY too much thermal paste. That's counter-productive. Thermal paste basically fills in the scratches/imperfections to help heat transfer. A goopy snot of bubble gum wadded there will insulate the chip, and it will have less cooling ability.

[HW MOD] LG G6(+) Terrible Thermal Throttling Fix

Hi All,
I want to share my experience with my LG G6 Plus (model H870DSU, 128GB, Dual SIM, 32 bit Hifi DAC, Android 8) and as the subject is saying, it has (had now) terrible thermal throttling. After some reading here on XDA and on the internet, I have decided to open it and at first just replace the thermal paste. But this solution was still not enough and throttling was not fixed as I expected. So I opened it again and removed the thin copper tape which is sitting on the "SoC housing". Under the tape is also a little and thin grey thermal pad, not sure how good it is ,as the phone was permanently overheating. Then install thin copper plate (15 x 15 x 0.5 mmm) directly on the Snapdragon 821 SoC, which has 15 x 15 mm dimensions.
SoC, copper plate and "in-built" heatpipe, all have been cleaned by IPA (Iso Propyl Alcohol) and AC MX-4 was used between SoC and copper plate and between copper plate and heatpipe.
Then I put everything together and run the "CPU Throttling Test" again, and the results are more than just a great now. And trust me, before the mod, I have tried everything to have such a stable performance, I even put the phone into the fridge, but it has always throttled. Now, after the mod, the phone is fast and smooth again even in heavy tasks with no lags.
Sorry I have forgotten to make pictures during the mod, so I just modified some pictures from the internet for better understanding. But screenshots from "CPU Throttling Test" app are mine.
Copper plate was bought on Ali.
Do not forget, you are doing it on your own risk, as always

hey man does it still perform well today? I just read this today and I want to try it when I replace the back glass of my g6
Hi, yes the phone is still working just fine.

do games still drop fps after this mod? because gaming on this device is fine until it thermal throttles.
I have this phone for almost 5 years, but never play any game on it, sorry
Some FPS drops will come, no matter what (its still only passive cooling inside the phone), but it should not be as bad as before the mod. I see benefits of this mod in daily tasks, not benchmarks or games (I have used CPU Thermal Throttling Test, only to show the difference between and after).
Phone is not lagging while browsing a web (Chrome) or switching between apps during higher usage like WhatsApp, Viber, Messenger, GCam. Also temperatures are going down faster after the load, because of better heat dissipation.
Anyway, keep in mind, that this is a Snapdragon 821, which is quite old SoC (6+ years) and if your preference is gaiming, I would probably go for something newer, with better thermal management, like Snapdragon 855 and higher.

do you recommend the lg v50? it goes pretty cheap nowadays.
hey @Jarko01 did you remove all of the copper tape? or just the part with the soc?

Yes, it could be fine upgrade if you can find one in good condition, which was never opened, damaged or is not missing any internal parts, like heat-pipe.

Hi, I do not know if I write in the right place but I have one question, I used this mod and when it comes to work it has stabilized a bit but looking at the processor power, it differs significantly from your copy at max and there is also thermal throttling, is it is it a question of a damaged CPU?
Thank you for this information. I am going to replace battery in a few months because its going to die slowly, i will replace defective fingerprint sensor too (heating and pushing on rear cover does not help). And now i will do this thermal paste replacement too. I have just purchased those metal plates from aliexpress.
Just one question: what is "black copper tape"? is it really copper tape? i did not disassemble it yet, i have just checked a few youtube videos and i see there some kind of black tape but is it really copper? do i have to reapply it after cleaning? or i can discard it?
thank you a lot
Well, to me it looks like copper tape. I have removed it completely, as it was more useless than useful ... we can see on screenshots "before-after".
Do not forget to check, if your copper plates from aliexpress are perfectly flat, especially on edges. Mine were not, so I had to do some "DIY" at home to make them flat.

my LG G6 is often a bit lagging, i dont know, it might be about apps requiring more and more resources (but on the other hand android should handle this resource issue well) but i am still happy to find out that there is a thermal pad/paste inside which can be renewed and i hope it will help a bit to breath life into my "old" phone. Unfortunately i missed to unlock the bootloader so i hope somebody will save us with a code generator soon
Thank you again for the tip
When I was on Android 9, the phone was a bit laggy "here and there". Didn't really like it. When I switched back to Android 8, smoothness is everywhere. Tried to switch to Android 9 a few times (allways clean install), but system was a bit laggy, so for my needs, Android 8 is the only way to go.

Thank you for the information.
Is it possible to downgrade from 9 to 8 if i dont have rooted phone, neither bootloader unlocked?
If yes i would appreciate if you could point me to the thread where i can find instructions. (Also what does clean install mean on an unrooted locked bootloader phone)
Thank you.

Hello mate, are you still using the lg g6 as your main phone?
Hi,
yes, the phone is still working fine running Android 8. Android 9 is just too laggy.
J.
Hello. I have used this mod. I put the copper plate as followed from the instructions, but the result didn't meet expectations even after downgrading to Android 8.
The pre-installation result wasn't uploaded to gdrive before reset, forgot to upload it so it wasn't here
This image shows the result on Android 9, mod applied. 25.11.2022
The second one shows the result on Android 8.
04.12.2022
Hello,
I did the test again to see if my cooling mod is still working. Even the spike is not the same, stability is OK from my point of view.
J.
Unfortunately i was too lazy to perform any benchmark, now i am regretting it a bit Yesterday i made a battery/cam glass/fingerprint sensor replacement and i have also performed this thermal stuff upgrade the exact way as you have described (the old paste was almost dry). I dont know if its performing better but i am glad i did it. thank you again for the idea.
