I'm using a Sprint Touch Pro at the moment..does anyone seem to notice any heat issues? I would be on the internet and the top part of the phone (near the camera area) would heat up like crazy and it'd shut down due to overheating.
I'm not sure if there was a thread started for this and I apologize if there was. I did do a quick search though, if there was point me in the right direction please!
Is there a solution to it as well? I read in ppcgeeks that flashing it to another radio might help? not sure though..
If your phone is heating up often you should notice the battery life being cut into about half as well. I have had 2 touch pros with this issue. Now all will heat up with the use of the gps receiver on. But if it is getting hot all the time then your gps receiver is probabily constantly looking for a signal and the device is defective. A different radio might get back in line, but most likely not.
Heat is a common Touch Pro issue. Even those that don't heat up too much to the touch get hot inside and depending on what you're doing will stop charging. Usually data connection activities cause it after running for a while.
You can monitor it using nuePower. That does not work well with WM 6.5, so anyone using WM 6.5 will have to use the Battery utility in HTC Debug Tools. Once over and around 47 degrees C charging stops. (I think the HTC utility is a decimal point off in its temperature readings.)
Anyone who has not experienced it simply is not doing the actions that trigger it, but it happens with all the Touch Pros. Seems it has been an ongoing issue with some HTC devices. Many people just never encounter the issue enough to notice. We've been discussing it for a long time in this thread. We also discuss ways to mitigate the heat there too.
If it's getting too hot to hold in your hand you SHOULD to get a replacement, but all of them have heat issues internally and at best will feel warm outside at times. The external feel is not the most accurate measure of how things are internally. The utilities that measure internal temperature measure best.
no I love my sgs2 and so does every that holds it, ive a major issue that i thought was caused by switching from orange uk to o2 uk, but as it happens i have full signal when the phone is rested down... however when i pick it up it drops signal... more often than not the signal completely drops out as does the call and sometimes it just goes down to 1 bar... does anyone else have this problem? ive tried my o2 sim and my orange sim its the same for both... is it possible i have a defective handset ? weak radio ???
heres my quick vid to show you what i mean, apologies for the video quality... filmed on my bb9700

well the GSM and 3G antenna looks to be located in the bottom, back part of the device. so this seems like the exact place your hand would be covering when holding the phone, so i can easily see some significant signal attentuation happening with this phone.
i dont know where the antenna was located on the original galaxy s. but all phones i own always have attentuation. not much you can do about it i'd guess.
Applies to all wireless devices - signal transmits worse through your hand than through empty air. Rules of the universe.
However, I can't seem to replicate what you're seeing. In order for bars to drop, I have to block the entire bottom of my device using both hands. Holding it in one hand doesn't seem to be causing a drop for me.
But again : air > hand for signal transmission.

That's right, quick start guide shows the location of the antenna. If you look at the back of the device, the antenna is in the lower left hand corner, opposite the speaker.
When holding the device in your right hand, it should rest in your palm.
Actually holding the device in my right hand doesn't seem to be affecting my signal though, for some reason. I might just be in an area with good signal though (3 bars of h+, stays at 3 bars when holding it in 1 hand, drops to 1 bar when covering the device completely with 2 hands, and then changes to edge with full bars).
I just tested with my S2 and I had no problems whatsoever.
See my youtube channel (../user/Poppefieke) Can't post links yet.
I have some other S2 video's there too
i think sampullen who has been posting quite a few vids on youtube is going to cover this now too, see i hold my sgs2 in my left had for holding when im surfing etc but also when im on calls...
its good to hear some of you cannot replicate this, maybe mines faulty might try to exchange for a new 1 just to be on the safe side
OMG!
can more people confirm if this is real?
is it as bad as the antenna-gate issue from apple or no where as bad
Hey (samjpullen) here
I have been doing the tests like Sticky and have been getting some rather conflicting results to say the least.
I am not in the best area for Orange so i get a weak signal most of the time, when i do the test infront of my iMac and extra screen with the TV, Sky (you know the drill) on it seems to drop down from H with 1 bar, then down to 3G then down to G and then it can jump onto the Edge network (rathe strange)
But when i do this same test in other rooms e.g bathroom, other bedroom, even downstairs with the tv etc on it is fine!
So my guess is that it might be my rooms location and maybe all the electrical equipment within a small space.

im hoping no where near as bad and im hoping that i was the only affected, one chap has placed a video reply to mine showing he doesnt have the issue which is good news, lets hope more can confirm im rather a 1 off and that if i replace this unit all will be well...... fingers crossed
cheers sam,
btw ppl follow sam on twitter, guys good!!!
i know this have been discussed before but there is still no solution.
here s my problem: wifi signal drops suddenly when i hold my phone. ive done sevral speed tests. These tests confirm that holding the phone results in a really bad wifi quality. I ve tried eveything.
does anyone have any ideas? even if its hardware moding
thx
+1
Sad to say, in my tests, by tightly holding the phone, especially at the bottom right, the signal strength reduced by about 20dBm.
Sent from my XT910 using XDA
this really sucks since this phone is pretty good and so far its the only BIG problem i found. and no solutions....
Must be a random problem. I have the RAZR and RAZR Maxx and neither has this problem.
For me, on 2.3.6 wifi signal was low, especially taking phone by bottom, but on ICS, both t-mobile ics and latest eu ics, wifi signal is very improved. Hand issue remains, but signal is for me stronger.
well i guess im just going to wait for stock ics update and hope it improves but im guessing the problem wont disappear since this is clearly a hardware issue. and if this is random then im very unlucky
When software fixes a radio that software usually just makes the signal-strength meter show signal that's not really there.
There are apps on Play that "fix" all kinds of radio problems by installing signal-strength icons with the low-strength indications set inaccurately. It *looks* like more signal, but it's the same low signal you had before.
Signal strength has almost nothing to do with reception anyway. Signal/Noise ratio is what's important, and there's no meter for that. One bar of signal in a very RF-quiet area, is much better than five bars in a computer data center.
"Caveet emter, I reckon!"

I have no wifi issues with this phone. The GNex however was unusable at 30 feet from a high-powered Hawking WAP, or an Apple Airport Extreme WAP.
If you have a plastic case, try removing it. Some cases are made with recycled plastic and are infused with conductive material that can act as a Faraday Shield, blocking part of the signal. Easy test, costs nothing but a few seconds...
yea i already knew about the plastic thats why i bought a rubber case. I have to say it helped a little but didnt fix it. the problem is still there.
thx
Haven't seen any problems with my wifi, although I mainly use the 3G simply because I have 4 GB of data a month and I will never use that much when I'm out around town.
If the problem occurs when holding it a certain way wouldn't the simplest solution be to not hold it that way, also be very aware of any metals between you and the router as metals block radio signals, how old is your house, if old enough maybe lead paint, unlikely but just throwing all possibilities out there.
thx for your help. i didnt only test this at home and as for holding the phone im used to hold it like i hold all phones and its pretty annoying if i always have to hold it differently if i want to use the internet
Have you tried the free Play Store app, WiFi Analyzer?
This will help you find out what works/doesn't as it provides more sensitive strength measurements from the chip. It's handy anyway, since it shows WAPs that you aren't connected to. yet.
It's quite possible that your antenna wire bounced off the connector. An insignificant drop of an inch could do that if it was never seated correctly. It would likely operate in a degraded capacity as a result. If you're OK with cracking the case open, that's something quick to check.
How long have you had this phone?
I have never heard anyone complain about the Razr's WiFi reception, so I suspect this is something unique to that phone right there. What is your idea of poor reception? 100 feet, inside, is the practical limit. 300 feet in an open field. Metal wall studs, sheet metal siding, all of these will stop radio waves dead.

Then you haven't been listening. The RAZR is universally acclaimed to have the worst WiFi reception of ANY device since 1999.
im ok with opening it... i actually opened it a couple of times and removed the battery but idk what to look for since nothing is labeled i dont even know where exactly is the wifi ship and antenna. i tested this as close as 6 feet from my router when i leave it on the table i get full wifi signal and speed test at max then i hold it and try... wifi signal goes down and speed test at 3/4 max speed...
thx
It's possible that I have an extraordinary phone then. I decided to compare.
My phone is seeing -60dbm from the Hawking extender that I'm closest to, which is about 20 meters away, behind three stick-frame (pine 2x4 studs, sheetrock) walls. The reading varies dramatically, depending on where I put it on my desk. So let's see what some other WiFi devices do...
My MacBook reads -58dbm. My iPad2 reads -59dbm. An HP Envy 15 reads -65dbm. And a Moto Atrix2 WCS (With Cracked Screen) reads -61dbm.
A transfer of 200MB ("random" data created via linux: 'dd if=/dev/random of=200mb.dat bs=1048576 count=200' so that compression algorithms don't skew the results):
Razr (6.12.79 ICS Black Widow): 9s
MacBook (Lion): 6.5s
iPad2: 10s
HP Envy 15 (Ubuntu 11.10): 7.5s
Moto Atrix2 WCS: 10s
I didn't repeat the test, and that is a busy WAP, but the results are what I expect for battery-operated devices. I also expected the ipad, atrix and razr to lose the race, since they have relatively slow storage systems, which have inherently poor write performance on files of this size (200MB won't buffer at all).
The WiFi cable will look like a white or black wire with a gold junction on the end where it meets the motherboard. I would expect that if you've had the phone open, you would definitely notice a wire hanging loose! I doubt that's the problem, but that wire is a coaxial shielded cable - like on cable TV only really tiny - and you can do all kinds of DIY replacement antenna stuff eg, adding an external jack so you can "beam" WiFi a mile away using a hacked Pringles potato chip can.
I actually think the problem might be RF noise in your environment. Florescent lights (CFLs), computing equipment, HVAC compressors, and motors can effectively "jam" WiFi signals, causing packet transmission failures to increase rapidly as the distance from the WAP increases.
We have a Fluke RF analyzer here, and our WiFi setup is quite good as a result.
Does anyone know if the Razr is unusually susceptible to RF noise? Maybe noise that the Razr generates from the motherboard/CPU/radios/BT? I'm not equipped to test that.
---------- Post added at 09:15 AM ---------- Previous post was at 08:29 AM ----------
Do you have other devices to compare the Razr to?
Did you try pointing all the rubber duck antennas on the WAP straight up?
I just checked an iphone, another ipad, another Razr, and a Dell laptop, and my boss's Razr was technically the winner on signal strength and transfer speed, but let's call it even. There are too many variables, and statistically significant benchmarking is beyond the scope of a forum comment.
The Razr has typical WiFi performance in this environment.
Thank you very much for your post. I did try with the desire z and the evo 3d which are doing jist fine wheather i hold them or leave them on the table: both signal and speed test are amazing compared to the razr (if i hold it). If you could tell me where the wifi ship and antenna are located (a pic maybe) it would be great because when i open the razr all i can see are metal plates everywhere probably for cooling. I dont understand what you mean by pointing all the rubber duck antennas on the WAP...
Thx again
I haven't had a Razr open yet. Even after dropping mine from a motorcycle and watching it slide into a ditch with an inch of water in it. Tough li'l bastards...
The WiFi antenna cable and connector are probably under one of the metal shields.
Most WAPs have 1, 2, or 3 "rubber duck" antennas that you can move to maximize the signal lobe pattern. You can use the WiFi Analyzer app to adjust them, but be prepared to walk a lot...
Others are just a box. The only one of those that *I* know of that works well is the Apple Airport Extreme. The Netgear Wireless-N HD, which is very highly rated, is a P.O.S.: it has a narrow, elongated lobe pattern, and if you're in that narrow lobe, it works REALLY well. If not, you'll be lucky to connect to it. Two people standing 10 feet apart, and one can have great service while the other can't even get an IP address.
The fact that you have other devices working well, and you sound like you've done this quite a bit, I'm guessing you have a problem inside the phone itself.
I manage about 200 phones here, and I haven't heard one word of complaint about WiFi. 3G/4G service? Yeah, lots of complaints about 3G/4G from people out in the woods or working in a valley.
These also work well as a WAP (tethering). We have a few of the Personal WiFi devices - a handheld that converts 3G/4G to WiFi for up to five users - but most people prefer this phone for that.
My old DroidX has a better WiFi antenna, but that's an exceptional phone with only one core: I spit on it. Ptui.
Hi,
I've been having a somewhat mysterious problem with the wireless internet (Wi-Fi) signal on my SCH-1545, hopefully someone here can help me find a solution.
Details:
At rest, my wi-fi signal is weak, regardless of which network or router is producing the signal.
I use an oversized Anker 7800mAh battery, which adds a considerable amount of weight and bulk to my GS4.
I am currently running a recent snapshot release of Cyanogenmod (11-20140804-SNAPSHOT-M9-jflte). The last time I updated was few weeks ago, but my wifi issue began sometime early this week. Thus, it seems unlikely that the ROM is to blame. For what it's worth, my baseband version is 1545VRUAMDK.
Oddly, after some poking around, I've discovered that applying pressure to the back of the phone near the lock button seems to increase the quality of my wifi connection. For example, at rest right now my phone shows a 30% signal; when squeezed in the aforementioned manner, the signal jump s immediately to 55-60%.
I suspect that there may be some fault with the wifi antenna connector, or with the antenna itself.
My best theory right now is that a mishap or fall with this bulky battery installed may have delivered a shock to the phone's hardware beyond what it is designed to withstand. Consequently, it seems that the wifi system was somehow compromised. I've tried cleaning the wifi contacts as suggested here[1] .
Has anyone had this problem? Can anyone offer a solution?
I can't go on using my phone like this, and to get a replacement will be quite costly. However, if I do end up getting a replacement, I have my eyes on a LG G3
Thanks for your help!

Have your tried doing a factory reset? I know this is a pain in the butt but maybe it will put your mind at ease. Have you dropped the phone or anything that would cause the antenna to suddenly become loose? Is your connection bouncing up and down or is it consistenly just staying low? Also before a factory reset try getting Wifi Analyzer from the app store and check to see whats going on. Just sounds rather buggy that it suddenly started happening.
Same thing been happening to mine just recently. Seems like when I squeeze the battery cover the wifi signal is stronger for a limited amount of time.

If you squeeze your phone and it affects signals take off battery cover and try tightning all the little screws around the phone with the battery out.. might help just saying
Thanks for your suggestions folks, but I still seem to be in a pickle.

I tried a factory reset, didn't seem to help according to Wifi Analyzer (thanks for the app suggestion). As I said in my original post, I fear that drop may have caused this problem: since I use a heavy extended battery, I expect the damage caused by any fall would be magnified.

I attempted this as well - I removed the back cover and ensured all the ribbon cables and antenna cables were making a firm connection, and then I tightened all the cover screws. Nothing seems to have helped. Concurrent with my previous statement, I fear one of the modules (specifically the wifi/bluetooth SIC) on the motherboard may have become slightly dislodged from a random fall.
Does anyone know of a way I can test this theory or get it fixed if such is the case?

i'm in the same boat, my phone is exeriencing the exact same issue. I've got a new back plate on order, hopefully replacing that and the wifi/bluetooth antenna will resolve it.
have you had any success since this post?
Hey,
So my Motorola G8 Power (PAHE0025AR, Argentina) arrived yesterday and as soon as I started using it, I noticed a big problem:
The screen is unresponsive in the edges, top, and bottom. I recorded a video so you can watch for yourselves:
https://streamable.com/et8iar
There's no way to touch the area outside of the rectangle I drew, it just doesn't register any touch events there, making the navbar really hard to use and it's impossible to pull the notification bar down in landscape mode.
Did this happen to anyone else? I also noticed, using the app "Multi touch test", that if you place 3 or more fingers, it kind of goes crazy, something that doesn't happen with other phones.
Also, I knew the WiFi would be slow (no 5Ghz support), but I have insanely high lag spikes on 2.4Ghz, which is odd because it's not happening with other devices...
Did anyone else experience something like this? Could it be because of the screen protector that comes with it? I don't wanna take it off if I'm going to return the phone, but I can't see how a thin plastic film can make the screen center work but not the edges...

mine did not come with a screen protector, so i can't speak for that, but just to be sure i would suggest getting it off, so you know for sure before returning it to the shop

i did a ping test ( to google) on 4g and on wifi , with 4g it averages around 40ms and on wifi it's around 20 ms this is a 2.4 ghs 802.11g wifi network
I have 3 G powers. The screens on all of them work. You may have received a bad unit. The Moto warranty covers manufacturer defects.
Thanks for your answers. I'm pleased to find out the screen works well without the plastic film that came with it.
However, I still have the WiFi ping spikes problem. It happens when connecting to any server, so I can't play any games.
I attached pictures of some ping tests. Notice how sometimes it takes so long in the terminal (over a second?) to ping that it times out and it results in a packet loss (3/20 and 2/20)
This happens only with my Moto G8 Power, tested the WiFi with other phones and my PC as well and they work fine (no spikes).

it can happen that there is some form of incompatibility between devices , in this case your phone with the current router setup.
if you have the option, please try another wifi accesspoint ( a neighbor or a friend perhaps) just to be sure you experience the same problem on all wifi. If that is the case we can assume a bad wifi chip or reception problem, else there might be a solution in changing your WiFi setup.
The WiFi issue fixed itself after one day and a half somehow. I hope it was just something wrong with my WiFi setup handling new devices or something like that. Didn't get to test it with other WiFi connection yet.
Thanks!
