S6 Edge screen won't turn on (but otherwise works fine) - Galaxy S6 Edge Q&A, Help & Troubleshooting

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...

[Q] Can't end calls in lumia 800

I have my lumia 800 for a week, and now its happening something strange.. When i'm in a call for some time, and i want to end it the phone doesn't let me. Its still responsive, i can go to the start screen, etc.. but the phone call remains on top with the message "ENDING". After a couple of minutes the phone freezs completely and reboot.
Someone had the same problem??
It's not happening always, but it's frustrating... I was having such a pleasant use and then this happens.. and i'm becoming a little sad and worried.
I dont's know if its a problem of hardware, it seems software because doesn't occur always.
Thoughts?

Yes, I also had some similar kind of problems today, i could not answer the call, after they called me about 5 times i could, but then could only speak a few words before the call stopped. Also i saw the call was still running after the caller had hung up. I wanted to retart the phone, but it would not start up again, then i took it loose from the charger , and it beeped and after a while it started up again by itself.After that it worked oke again.
I think they have to look seriously at the software, there is something wrong here i believe.
I've also had this problem of calls not ending on occasion. It seems inconsistent so far though. I'd be interested to hear if this seems to be affecting everyone or if it's only a small number of handsets.
I have the same prb. The screen goes blank and cant end calls. Has to force restart

For all WP7 devices the screen automatically goes blank when you are on a call and the proximity / light sensor detects your head up to the phone. However, if the screen stays off when you move your head away from the phone it means your proximity sensor (or software related to it) is faulty as it still thinks you have the phone to your head.
This happened to my HD7 after a nasty drop on a tiled floor the other day; the sensor was dislodged and permanently was set to the "on" position. I could only end a call by pulling out the battery, unless the other party hung up first. And every time my alarm went off in the morning the screen would remain dark and I would have to press the power button to get at the snooze button (this is because the sensor is telling WP7 that the phone is in a pocket or somesuch, and not to turn on the screen as the alarm could be accidently disabled or snoozed).
I fixed it by dismantling the HD7, resettling the sensors and blowing out as much dust as I could. Has been working fine since! I wouldn't recommend doing the same for your Lumia 800 though...
I dont think it is a proximity sensor issue. In doing tests, the sensor works perfectly for calls if I only have the screen off for a short period of time. If I hold the device up to my face for say 30 seconds, then the device usually freezes up and the screen goes blank, not allowing me to end a call. This makes me believe that it is a software issue that, hopefully, nokia can sort out.
Well i have been quiet on this topic as i wanted to see if the update fixed this problem BUT NO.
Today i made a call and it didnt ring but said connected i then pressed end and nothing it didnt respond infact none of the keys did anything my lumia just froze.
I couldnt even turn it off so i took the sim out and nothing still conected i just had a phone that was frozen with no way out .. so i had a usless lumia all day at work untill the battery died..I HAD NO PHONE ALL DAY !!!
I just hope it was not connected properly or my bill will be huge from t-mobile ..
This has happened a few times befor the update and always always when the signal is quite low it seems ..
But its a joke when im stuck with a usless phone all day ..
NOKIA SORT THIS OUT ITS NOT ACCEPTABLE
Hopefully this is a software issue and we haven't all received a bad batch of lumias with wonky proximity sensors.
Is there absolutely no way of reseting / rebooting the Lumia? you just have to wait for the battery to die??! That seems ludicrous!
i face the same problem many time i reset the phone by pressing power key long.
i find if i was in 3G network this problem some times happen ,so i switch off 3G and now it more than 3 days it never happen
Well to answer that question ...no its happened nine times last week, 3 of those 9 the phone is usless and you have to wait for the battery to die..maybe that's why Nokia gave us a short battery life haha, the other 6 times after about 7 min you can turn it off to reboot and the rest of the phone is responsive .. So 30% of the time when it happens U have no phone :[ even a long press of the power button does nothing
Same problem here... You can restart the phone btw: Hold power button for 10 sec, then release the power button and press it again...
This is a big problem for me, hope a fix comes in fast...
Thanks,
Samo
Im having the same issues here. Other than this its a great phone. Hopefully get it sorted soon.
same problem here, although never had to wait for battery to die.
long hold of power (10sec+) usually reboots the phone.
I keep noticing the problem when changing locations (inside/outside buildings) which is usually connected to switching to 3g - if it happens during a call I am unable to end it with screen being responsive and phone saying that it is ending call (for 30 seconds and more)
contacted Nokia regarding this problem.. they told me to reset my handset.. this is the only option they have... DUMB
same problem here... did someone find any solution?
nopes........

You can hold the power button for 10 seconds, this will trigger a reboot.
I'm relatively often facing the same issues, worth noting is that it does seem to connect the call as I have had customers tell me they heard me grumbling before the call got disconnected (so I gotta be more careful with grumbling )
Happened to me last night, just turned the phone off (power for a few secs then slide down) and on again.

[Q] How do I force the screen to stay on while charging on USB?

Running the newest UnNamed and I'm trying to find a way to keep the screen on while charging from USB. The point is to keep the screen on while driving. At night I charge with AC power so that's not an issue.
I found posts saying there was a burn in problem with SMOLED screens being on with a static image for more than a couple minutes at a time. I haven't seen it personally but if anyone has first hand experience with this phone or the international model, please speak up before I damage my phone.
Otherwise, once again, it looks like I need Tasker for the job. Have it detect bluetooth connection for the car and upon usb power trigger car mode and keep the screen on at ~50% brightness. something like that.
With unnamed go to Settings>Applications>Development and click Stay Awake.
Try this first,
Menu->settings->Applications ->Development -> Stay awak
If not working , try this
Menu->settings->Display->Screen Timeout ->Never
Now I've never seen permanent burn in on my SGSII or Nexus One (even while on constantly during a 10h drive to Vegas). I was using a stop watch app on my Nexus One, and while only on for 5 minutes or so, I did see it burn in, but it went away after a few minutes of being off (boy was I scared when I first saw it though).
Now, I have personally seen permanent burn-in on a Vibrant (not mine).
Funny thing is the screen timeout is set to like 5 seconds on it, so it's barely on. Yet I can clearly see the clock is burned into the screen.
Have you tried running a car app to hold a screen lock? I know Google Maps can do that. Plus it doesn't require going into settings (at least more than once).
EDIT: As a simple observation, the burn-in seems worse when it's white on a black background.

Samsung Galaxy Alpha Screen problem

Hello everyone, this happened just today. I was using my galaxy alpha AT&T and all of a sudden the screen starting glitching and jumping. I was quite shocked because I bought this phone a few days ago. Although the phone is not brand new but the vendor told me that it's completely fine. Anyhow, I pressed the power button and waited for a few seconds then turned the screen back on. This time the screen was fine but after a few seconds of usage the problem started again. Now i read on the internet that this is not a screen issue but rather its associated with phone's charging port but I'm not sure. And another interesting thing is that the screen shots are completely fine and there are no signs of glitching or flickering. Secondly also note that I was experiencing the famous "cannot charge because battery is too cold!" message and I believe that this problem is also associated with the charging port. So please if anyone is familiar with this problem then guide me. Here a video link that shows what's happening to my screen

If you have the screen on the lowest bright setting the flickering will continue. Once I put it back on auto or at a slightly higher level the flickering went away. That's at least what fixed mine.

I've never had encounter this kind of problem. Your problem is too severe. I think it is related to the hardware.

Flashing/flickering/artifacting screen?

(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .
So better request for a replacement from huawei . but don't mention them that u bought it used . tell them u bought it new

Black Screen

I have run into these issues several times. They seem to be related, but I can't say for sure.
Every now and then while I'm actively using the phone, 1/2 the screen will go away and the phone will be unresponsive. If I shut off the screen, then turn it back on, it usually clears up. Sometimes the screen won't come back on. It stays off no matter what buttons I press. So I put it on the charger, that triggers the screen turning on and everything is back to normal (the battery is always over 50% or more at this point). Yesterday this got to a point of happening several times in 1/2 hour, so I ended up rebooting to see if it would clear it up. This issue did not come back since then.
On a similar note, I was playing a game this morning in a dark room with the brightness turned all the way down. I was being very active in interacting with the screen. Every now and then the screen would go black, except for the notification bar. I could still see that (time and statuses of things running). The screen would not respond to any touches, so I would shut the screen off and turn it back on and all would be good. This happened 2-3 times over a 45 min period. I play this game quite often, but not usually in the dark and often not as actively as I was doing. My resolution is set in the middle (FHQ+ I think it's called).
Has anyone else run into anything like this?
This S9+ snapdragon through Verizon just seems to be plagued with so many minor issues. I've never had a new phone with this many problems.

As a followup, I think I have found the problem. It seems to be with a product called Game Tuner. It can black out the screen while leaving the app running in the background. I think it is buggy. Doesn't seem to be a way to shut it off though.

I was able to uninstall, then install an older version of Game Tuner and the problem that was easiest to reproduce was fixed. Hopefully this will prevent the weird 1/2 screen thing as well.
