Hi,
Has anyone experienced an abnormal temperature in the nav keys area? It is present in any moment that the screen it is turn on, even on recovery with twrp or with different roms, increasing with time. It is safe continue using it?
A little background first: a couple of months ago I had the screen replaced, from nowhere the old screen started to blink and went black with a burned smell. Before this happening never noticed this issue before.
Appreciate your help!
There are not many chips in there. It's probably something with USB power management. Is your USB port working? I mean both client and host functionality?

My USB is working normal I can acess my files and charge the device too. But I don't know what you mean about the functionality part
I mean chip providing 5V for OTG. If it works as well problem could be caused by battery, but I think that heat wouldn't be concentrated in lower part of the device
Hi g4m4r1,
I have this hot area in the middle of navy keys (home button) bottom on the screen. But my device only warm when I am playing games or when I use the screen brightness over 70%.
So, in indoor usage my screen brightness is around 30% and this area is just little warm.
Other important point is the ambience temperature, in my country is summer right now, so my device get this hot area very fast when I start up some game or increase the screen brightness.

Hi Fabio, thank you for your contribution, I did some testing and seems that brightness has a role in heating the nav keys area, by the way mine, it is not concentrated only at home button, but well distributed on the others buttons too.
At low brightness, just enough to see what it is on the screen, the heating rate is lower and increases, but at high brightness it is almost unbearable to the touch. About the weather part, that doesn´t seem to affect the area. But still I don't know if is prudent to me continue use the device.

Since I knew everyone would think I lost my mind, I verified this for weeks before posting it...so here it goes!
When I charge the device at work (with the power on), it sits on my desk about 16 inches under my overhead cabinet that has fluorescent lights underneath. The lights somehow triggers screen actions on my HD2! It's the strangest thing I've ever seen! After about 30 seconds, the device looks like a ghost is randomly tapping the screen, randomly starting programs!
This NEVER EVER happens in any other condition--outside under sunlight or while the device is on any other surface where the fluorescent light is higher up, like on the ceiling. I have no problems with using the device otherwise.
It's just strange and I'm wondering if anyone else has ever seen this...
hmm interesting.
Might there be power running up inside the wall near the phone too? PC and monitior around it?
could be patches of field building up just enough to fool the capacitive screen, or maybe exciting the grease on teh screen or some such.
Course there has been a lot of talk about ghost taps, is it really only ever happening there?
Could be you need to change the starter plug in the fluorescent, if its a standard strip, they can hold quite a charge, and if its on its way out it could be losing charge to the air.
Especially when you look at how many electrical items we have on/near our desks, easy to build up a standing charge.

Someone also mentioned the fact that the flicker on my fluorescent desk lamp could be the cause. I saw a video where someone was able to "tap" their capacitive screen using beams of light, lasers, etc.

so I returned my sgs2 today and got a new one (old one had scratches). Now it seems to me that there is some flickering with black lines (very faded) on certain brightess settings on mainly white sites using a browser.
I noticed the flickering appears around 16% - 19% brightness settings (using "brightness level" from the market).
This flickering only appears only if "auto adjust screen power" is NOT selected, same brightness with it activated shows no flickering.
Also last but not least if plugged in with USB cable the flickering stops as well.
Can anyone re-produce this flickering?
1. Download "brightness level" from market, go between 16% - 19% (try step by step), with me its strongest at 17%.
2. Ensure "auto adjust screen power" is deactivated under Settings>Display
3. Open Internet and just look at a mostly white page
4. Ensure USB is not connected.
Can you see some slight flickering? Lots of lines across the screen?
Wonder if its just me, might go back and return this one tomorrow then
I assume no one suffers from this issue?

No flickering.
I get black/dim horizontal lines flickering on the display at low brightness regardless of my "auto adjust screen power" setting. I'd describe it more as a shimmering of the screen. It's very distracting - I first noticed it whilst trying out the Kindle app and it made it very difficult reading the text.
I believe it's down to interference with some radio component of the phone. I've searched various forums and haven't come across many mentions of this so maybe it's a bad batch and I'm considering returning mine. It's frustratingly variable so I hope I can demonstrate the fault in store...
I'm wondering if the increase in brightness just masks the effect rather than eliminating it. At lower brightness settings, any local differences in brightness are going to be more noticeable.

have you noticed any change at certain battery levels?? Like if the battery was at 90% its easily noticeable, once its like below 70% I'm not able to re-produce it, no matter what I try down to 0%.
So maybe since it seems to be only from 90% - 70%, it could be to do with the current/voltage at certain brightness levels with white background...very unique problem it seems..I'm thinking of going to the o2 store but I most likely wont be able to re-produce it then and there so will they still exchange it? hmmm lets see..

I'll note down what the battery power levels are over the next week or so.
I went into the O2 store after work and reproducing the effect was indeed difficult. I had it showing the effect in the shopping centre whilst sitting down at a bench. I had it showing the effect whilst in the queue to wait for an O2 staff member. Fifteen minutes later, once I'd got to talking to the staff, it worked fine. All I could do was explain the problem and ask if anyone else had reported it. They advised I "kept an eye on it over the next couple of weeks".
Really frustrating. I'd entertain the possibility that my eyes are faulty but I've shown the effect to someone else and they agreed it was distracting.

Hi,
I was not able to reproduce it using your directions, but I have to say that I also noticed horizontal lines flickering on white.
I tried to reproduce it but I can't find out what it is related to.
So it's doig it just in random fashion

does it flicker with auto brightness on? You might want to download an app like "brightness level" and set it to different settings to see when/where it flickers...mine usually flickered at 17% screenbrightness when battery was at 70 - 90%

Yes I did download it and followed yur directions to try to repruce it. But I could not. I set then brightness to various level from 100% down to 0, but no luck. I have to try now when battery is at that level. Then it could be some kind of intereference. Lines I noticed on mine are very subtle and close about 1 mm
Ok, confirmed: 92% battery, brightness 17% on white or close to white screen color, there are horizontal lines like some itnerefernce/noise. Annoying
Samsung galaxy S2 screen flickering
I also have the same screen flickering problem.
it happens when the battery level is around 87-91%
Any soulution?
same here
black lines around text on white background. It disappears after a while, but is really annoying. I suppose the only solution is to change the phone?
sorry guys to hear u got the same problem....I never found a resolution to it apart from returning it to the store....once I managed to reproduce the issue infront of the manager he swapped the phone straight away.
If you got the same issue make sure you get to the store with the battery level and brightness level that shows it up, ask to go into a dark area to show it properly.
First o2 store I went to the guy refused to look at it properly and as it was light outside he couldnt see it anyways. Second o2 store I went to, the manager went downstairs with me and turned off the lights to see the flickering because it shows only on low brightness so make sure you take that into consideration when in a bright/well-lit store.
i have the same problem, it, but it only appears when "auto adjust screen power" is on. Its really a shame! Only way to fix it is to change the phone?
same here. flickers at low brightness with battery under 90%. called samsung hotline. the problem was new to them and the only idea they had was resetting the phone. tried it but unsurprisingly its no help. galaxy s2 could be great but it has just too many annoying hardware flaws
Same problem
Well I noticed this on my SGS 1 !! ... when I have PACKET DATA turned on this flickering starts. It starts really hard when i have this function turned on, but when i disable it there's nothing...
Noticed same problem on SG2 bought in Sweden
Realise this is an older topic but i have recently noticed this issue in low light with Auto On. Battery level at 85 percent. For those that had their phones replaced did the issue continue? Has anyone seen this with the yellow tint also?
Noticing this issue as well on Villain ROM 2.4. Auto brightness enabled and 90% battery.
*Edit* Just did a CWM restore to stock rooted and the flickering seems to have gone. 85% battery, auto brightness enabled.
phone swapped... problem kept
i got my phone replaced 2 months ago and was very happy with the new one since it had no screen flicker... until now. so my current sgs 2 now also suffers from screen flicker and my only options are to send it to samsung and hope to get a replacement or to live with it. and since im beginning to think that this might be a general problem i tend to keep it. although i have to admit that i dont like my sgs2 as much as i did before...
Hello,
theres a bug in automatic brightness: if you turn it on and hold it against the sun the brightness will go to maximum but it won't get back (darker).

I can't help myself, 3 thanks virgins in 2 days!!!! Owned!!!! last time I held something up to the sun it melted. Its kinda hot!!!!........
Ok in all seriousness I have not had this issue....did you try rebooting your prime? I have noticed some hicups from time to time, like touch tones stop working....but if I reboot it will work again. I am sure its just the newness of ICS, these things will get ironed out in time.
I leave it off anyways. Its a known automatic brightness is a battery drainer. You'll get better battery life with it off.

I think this is more of a feature than a bug, although I keep mine at one certain level anyway.
It's to give you a more seamless experience, as soon as the screen goes off and back on it adjusts. It's so when you're reading an article and move from one area to another, you don't get a surprise mid-sentence. I always hated reading things off my phone with auto brightness on, couldn't just focus on the words had to keep tripping up on a constantly changing screen.
With sun i meant that you can hold it against a bright light
Sry for my bad english...
I've actually noticed some differences in the sensitivity of the light sensor on various units. Some do seem to get "stuck," where others maintain an accurate measurement of ambient light. This seems to be correlated to newer units (e.g., C1 units).
The one I'm using right now does switch lighting both more quickly and, it would seem, more accurately. The ones I had previously would get stuck either on high or low brightness (with very little adjustment in between), and I needed to toggle the auto brightness button to get them to adjust to new conditions.
I found auto brightness on the device to be an annoying burden if anything. I just keep it pretty low all the time. Better that way anyways.
Same problem here - The brightness goes up under bright light, and won't readjust until the next screen off/on or reboot.
Does anyone have a Prime that adjusts back down without turning the screen off?
I swear it's intentional and not a bug, although they should offer you the option of controlling its parameters. Just have to wait for the unlocker and some custom ROMage.
But seriously, I think it's to keep a continuity in your current session, so that if you're gaming or working (the two things this tablet's for) you're not plagued by an ever-changing screen that distracts you...

I can see how the concept of continuity can be good. But in my case for example, switching the bedroom light on - followed by a certain increase of brightness on ATP - then switch the bedroom light off to go to bed - the persistent brightness (tested for >15mins) can be a little straining on the eyes. Although readjusting the brightness is as simple as 'clicking' the 'auto' icon on/off again so that the brightness comes down to appropriate level (it only takes 2seconds to do it) - I think this is defeating the purpose of having the auto-brightness setting in the first place.

Oh I whole-heartedly agree. Going from my living room anywhere else in the house causes blindness with auto brightness on. And it acts completely opposite on this device than all others I've touched that use the feature. And like you say, if it's "automatic brightness" then why would it not be totally automated?
I'm just saying there's definite reasoning and programming behind it, it's not just some bug per se.
Therefore, don't expect ASUS to do anything about it, it'll all be up to our wonderful dev's here; they'll say it's properly functioning even though it's bass ackwards from everything else in existence.
The button light is always on when watching online video or any local video. It is annoying especially in dark room. The button light is too bright and distracted.
It also consumes unnecessary power.
Any way to turn it off?
Unfortunately no there isn't, however the brightness setting may lower it.

Nope, it doesn't consume power, not when your screen is lit up! The power the little LED lighting up 3 buttons requires compared to that point of time when you 4.7 inches of screen is lit up is lower than negligible!
Also, no way to turn it off. It's the phone design. Only way is via some registry settings (if). However our bootloaders are very secure and no one has managed to get around it -so can't access registry either.

Also, I can feel the heat coming from the bottom of the phone (where the "windows phone" logo is printed) when charging and watching youtube simultaneously for appox 20 minutes.
I know heat should be normal but surprisingly it is from the bottom of the phone but not the battery compartment.
Is this heat from the light ? Or from the antenna? or cpu, mother board etc?

...and it is very normal for most windows phone I am presuming. I have a Lumia 800 and HTC Titan, both have that behaviour. Considering they have only 1GHz processor you can imagine that when you run processor hungry tasks your phone will use up all the power it can ideally the closest to 1GHz and hence the heat. You will it more on Titan due to aluminium body. I am guessing Titan 2 is less hot. Also my Lumia feels less hotter too due to it's polycarb body.

Hey guys, can anyone tell me what the heck is this and how did I manage to get one after 12 months of using this phone?
edit] sorry for not explaining it, it goes along left edge of the phone, yellow mark near the charging port. I didn't notice it until yesterday and its visible a lot in live, I don't know how good can you see it over picture
hey guys, anyone?
Most phone screens go yellow from exposure to heat, perhaps your screen on that spesific are has been exposed to heat or preassurr

I'd say locked pixels but seeing it happen with phone turned off, yeah it's probably from heat.
I can also explain how.Sony uses a "liquid cooling thermal pipe" which takes the heat from your chipset (approximately below the N (NFC) letter on your phone's back) and delivers it to the left edge of your phone, towards the charging port to be more precise (your yellow mark is also at that spot)
You may have used your phone very heavily in extremely hot environment.I've seen my previous phone's screen go all weird due to heat (chipset @90 C) but it was fixed after a bit of waiting, to do this kind of permanent damage you must have used it heavily for long period of time, long enough to burn the screen via the heat coming from the heat pipe.
I doubt you could get it repaired for free, they would know it was because of heat and if your phone is unlocked, you have no chances at all because they can just assume that you overclocked your phone.

Mine goes yellow on the nav bar but only when its hpt usually when the battery is above 40°c but this occurs mostly when I'm charging
First of all, thanks for answering to all,
Second, you cannot see it when the phone is off, the first picture is with gray picture on it so you think it's off. When the phone is cold started, the mark is almost invisible but after some minutes of using it becomes visible.
The phone was never unlocked, neither was heavily uses, such as maybe gaming.
I just wanna know can I claim my warranty on it since I'm sure no pressure was made nor was it exposed to heat, but I first need to probably repair my cracked back screen.
