Hello,
I've noticed lately strange thing in my new S3 (not branded, not rooted, official 4.1.2). I've spent Last weekend in mountains, it was about -9 celsius degree, and I had my phone in an external pocket so it had probably frozen a little. When I tried to take a picture, the screen remained dark, only the touch buttons lit. When I tried to reboot with the side button, I saw "samsung galaxy SIII..." sign, and a blue wheel, and heard the sound, but than the screen remained dark.
The phone rang for an incoming call, once I was able to answer by touching the dark screen, second time I failed to answer (obviously it got colder).
After moving the phone to internal pocket when it got warmer, screen got back to life.
It happend again when I put my S3 into holder in a cold car (still in the mountains - though I wouldn't connect it with the altitude above sea level ).
I'm curious if it happend to someone else?
I wonder if it's due to AMOLED properities, or rather hardware malfunction?
I will contact support, but since manual recommends using the phone in 5-35 C degree temp. range, I'm affraid, they can evade.
Now the Q&A section is sad because you ignored it

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.

During a phone call, my proximity sensor doesnt seem to be sensitive enough. The screen turns off when I hold it to my ear, but when I pull away to look at the screen and interact with it, the screen either doesnt turn on or it will flash on and off again repeatedly. It seems that the phone cant detect that it is not near my head any more and should turn the screen back on.
Generally it wouldnt be a big deal since the screen does turn off when its held near my head, but when I needed to use the dial pad for a menu prompt it got really frustrating when trying to press in numbers with the screen switching on and off. (I just called Verizon CS recently and navigating through the menu was a pain with this screen going on and off).
I'm coming from the Samsung Charge which was very responsive: when you pulled the phone away from your head, the screen instantly turns on for you to press in keys or hang up. With the Rezound, it doesnt turn on most of the time and I have to press the power button (which will turn it on and then automatically off again...). The problem is alleviated if I'm in a very bright place (direct sunlight) so my guess is that the proximity sensor may not be sensitive enough to detect the difference between darkness and low lighting conditions. I'm sitting in a room with a 26W CFL lamp (so not too dark) and the Rezound has trouble turning the screen back on during a call when I pull the phone away from my ear.
Was wondering if anyone else exhibit this condition or if its just specific to my device (in which case I'll have to give Verizon a ring to get another replacement)?
I'm having the opposite problem. It unlocks itself a lot up against my head. My thunderbolt did this so bad I got a replacement thinking it was a defective proximity sensor. But it wasn't and I got in the habit of manually locking the screen on calls. But now my rezound does it but not as bad. I think htc sucks with proximity sensors cuz auto brightness is never programmed properly. It doesn't go dark enough compared to Samsung and motorola phones with auto brightness on. It only has about 3 brightness levels like in the HTC brightness widget, whereas stock Android has 5.

I'm having the same problem. The sensor would force the phone screen off as soon as I make a phone call. The verizon rep had me hard-reset while I was on the phone with her. The same symptom arises after the hard reset and the phone is brand-new.
I had to reset to get her to send me another rezound replacement.
On this replacement, however, I'm having the same issue again. My gf's rezound doesn't seem to have the issue.
I'm having a second replacement sent now. This is pretty annoying.
The interesting thing is the issue comes and goes. One day the sensor wouldn't respond, and other days it works fine. Although I would say that the issue deteriorates over time and never improves.
My S2 is in excellent condition, and works perfectly - however...
If it gets cold, just using it in 0-10 Celsius conditions, or not using it, the screen screws up. I get horizontal lines at almost even spaces down the screen, about 1cm apart. If it gets cold for too long, the bottom quarter of the screen freezes, example, the home screen, or whatever is currently displayed stays on the bottom quarter when opening apps, or scrolling etc.
When using the phone at room temperature etc, it is fine
Has anybody else had this problem?
Only had the phone for less than a year, bought off eBay as new, and I have flashed the phone to unbrand it from O2...
So, I suppose I have no warranty now...
I had a job a few years back in the north of Sweden where it was quite often -10 to -25°C. The same thing happend to my old SGSI. There was no permanent damage. Try to keep your phone in an inside pocket close to your body heat.
U're not the only one, I have the same problem and I even went to the service and had it changed but the lines are still there. So I guess it's a fabrication issue.
My phone was working fine when I went to bed last night. I laid it on my night stand and this morning I noticed I couldn't get the screen to light up. The blue LED was blinking like I had messages. The Menu and Back buttons light up when I press them, and I can even hear when someone is calling me, but because the screen will not light up, I can't answer. The phone screen is in near perfect condition, not a scratch or crack on it and I also have a cheap protective screen over it.
Hoping it was just a glitch, I removed the battery and held the power button for about 45 seconds and powered it back on. Same thing, black screen during the entire boot process, no logos or anything. I also tried to boot it in safe mode with same results. There is only one time that the screen shows any signs of life and it only happens when I first power it on. In the top left corner for a split second, where the usual "Bootloader is unlocked" message appears, it displays a small rectangle of colored artifacts inside that small message area.
I assume the LCD went out, but I'm concerned it could also be related to the GPU or other hardware, and so don't want to spend a lot of money buying a LCD if it's something else. I can still connect it to the PC, so I'm hoping someone knows how I can test the hardware from the PC, or at least recommend something. Right now the phone is ringing and I have no idea who it is...this sucks!

Hi everyone,
I'm sure this question has been asked by many users, but for some reason none of the ones I read seem to match the problems with my S6 Edge.
The other day I was playing music Youtube on my 3 year old S6 edge (for like 30min) and I forgot that autoplay was off, so the screen turned off, within 10 seconds of it doing so, I pressed the home button to 'wake it up again', but the screen won't turn on. the phone reboots once by itself but the screen remains off, and I know the phone's on because of the blinking LED light of messages, or the red when it is charging. The backlight lights up too, and it seems the screen's touch system works, as I am able to turn it off. I wait for a couple of minutes before hard resetting it (Volume down+Power key) and the screen lights up again and it's all good.
However, I have noticed this happening way too many times lately and noticed a bit of a trend. It usually happens when I use any app (except the music app) for 30 minutes or more, and if I manage to keep the screen awake, it works perfectly fine. The problem begins when the screen sleeps due to inactivity, or is voluntarily turned off. It also heats up quite a bit.
I am on the latest firmware, and have already formatted the phone once and tried, yet the problem persists. With that I suppose we can rule out that the problem is due to any third party app, or due to not updating the firmware. I also replaced the motherboard last year at a reputable phone repair shop, so I think it's a safe bet to say that's not the issue, but I am not 100% sure (the problems began 6 months after I 'unrooted' the phone, after replacing the motherboard).
As I kept going with it, it kept getting worse until eventually, now the phone is in a constant state of 'screen off but phone on', where it charges, plays music, can receive calls and messages, but cannot turn on the screen. I kept trying at 15 minute intervals to no avail, even though the phone is at room temperature.
Before I go blow a couple more 100 bucks on fixing this, I would like to hear all of your opinions on what the problem might be (and hopefully the solution).
Thanks in advance.
i have the same problem but i have the galaxy s7 edge. often i can unlock my phone but my screen will stay black. no aod or backlight but the vibration from unlocking with fingerprint is there and the sounds of opening an app are also there...
