I used my 8525 to listen to music over the internet for the first time (4 hours) and then went immediately into a 20 minute speaker phone conversation and I noticed the unit was very hot and the screen had various opaque colors of blue, green and pink in the background - the today screen was still visible, and my battery was beeping at me (not to surprised about the battery). I immediately ended the phone call and turned the unit off and put it on the battery charger for about an hour. After the brief charge it seems to work correctly. A few questions: Should I have not put the unit on the charger and just let it cool down? What was going on that made it get hot, and what made the screen turn colors? Should I expect this to happen again in the future, if so what should I do next time? What could have happened if I had let the condition continue as if I had not noticed the situation?:

Does not sound too serious. The heat is a bit to be expected due to the GSM radio transmission and 4 hours of music. They do get pretty hot. The colors on the screen sound more like a screen refresh issue (hopefully not screen being squeezed due to heat). If after a soft reset or turning it to standby and back the screen is still giving odd colors for a while I would have expected a more serious problem Given that after turning off and on it was fine, then much more likrly to be a software overload.
I might have let it cool a little before putting it on charger as this in itself can generate quite a bit of heat.

Hi!
I dropped my defy in 2 cm of water,everything was fine for 20 min, suddently my screen stop responding, i removed the battery, place it back turn on the sceen got quite dark. Yet I was still able to see things on screen. Then it slowly got darker and darker until it was completely black. After that I tried to push the power button but the screen didn't light up, only the 4 buttons were lit.
I noticed I was still able to unlock the screen or answer phonecalls sliding my finger from left to right on the correct area of the screen, although it remainded black all the time.
What can i do? do i have to replace the lcd?
Thanks
So I dropped my S4 on the kitchen floor - bang, screen cracked and nothing happening. Tried replacing / charging battery. When I hit power button I get a vibration, green light goes out for a few seconds then back on - nothing else.
I'm guessing the whole OLED has gone? - or does it sound worse?
DOH!
hi . i have v20 h990ds .
when i turned the second screen Off when main screen is On , in setting , the phone didn't show any thing (that is normal) but if i go to completely in dark room i can see that pixels of second screen electrically are On (black backlight can be seen without displaying anything). while i expect that when i set the (second screen being off when main screen is on) the power of second screen getting to off and don't use any battery .
when i press power button to turning off main screen , the second screen goes off at the same time as the main screen , completely.
can anybody tell me that is it occurs for you , please? is it normal when you turn second screen off the power of it (that can be realized in dark room) don't turned off?
That is completely normal. The second screen and main screen share the same backlight even when turned off you will still see some light bleed through the black pixels. They dont have separate backlights so it is still on behind the screen.
Hi! Well as many people don't know but Lg v20's main screen and the second screen are the same panel having a Cut around the left corner which make it feels like that Both displays are separate and also they make some kernel tweaks to make them virtually separate.So even you turn off the secondary display its backlight will still Remain on.
Thanks
Hi,
I have this phone for little over 2 years. For over 1 week now I'm experiencing my phone not being able to wake up when I use the power button/home button. Whenever I push the button, the screen flashes for like 1s blue color, you can also see that the notification panel is blacked out and part of it green and it doesn't wake up. Sometimes it doesn't even flash. It used to take about 10 tries to wake it up but today I couldn't wake it up. I performed soft reset, I couldn't see the booting animation at all but it rebooted, buttons lit up and I was able to get in. It's like the phone is working fine in the background but the screen doesn't light up. I can turn down/up the volume, take a screenshot, get into settings, open apps, write a message but the screen is black. Even my alarm went off this morning but I couldn't dismiss it.
I downloaded an Always On Display app. Although I don't actually see the screensaver when it's locked, it's still on and it's easy to get in beacuse of it.
It all started with the screen flickering on minimum brightness. In February this year I had the screen replaced for the same issue but this time it's worse because of the blacked out screen.
Any ideas what it could be? Faulty display again?
Thank you

It's over to have this phone for little over 2 years now you should have to change
TIP:
Flash a new stock rom of your phone from sammobile via ODIN.

That would be great, but I'm not a person that buys new phone every 2 years. I was thinking about it though .
When it comes to flashing. Do you think that would help? I don't want to end up with a black screen unable to set the phone up again. Cause overall it's working great .
Hi, i have the same problem, i'm from Belgium, and I have blinking screen problem and wake up screen problem :s
is it a software issue (nougat???)
before the big update (marshmallow i dont have any problem)
i'm on firmware A510FXXS7CRJ6_A510FLUX7CRJ1_A510FXXU7CRJ6_HOME.tar.md5
Turn screen brightness up abit to stop the blinking of screen. It's an issue of the screen hardware itself at low brightness after wear and tear. As for the hanging issue, maybe it has to do with your AOD app? Try uninstalling the AOD app OR flashing a stock Rom OR custom rom OR factory reset and use your phone at a higher brightness that the screen does not blink and see whether it still persists.

Thanks, because of my past experience with the same problem earlier this year I know about that "solution". Unfortunately, it makes the battery die faster as expected. Which is sad because I used it mainly on low brightness. So it's really not a solution at all.
I got rid of the AOD app because I found out that the phone lights up on 2nd try. AOD didn't work at all. I have to wake it up, put it to sleep and wake it up again which is always successful and the screen lights up. The screen flashes white about 3 times in a row now otherwise it works.
I haven't flashed it yet although I wanted to. But I will see what can I do. Thank you though!
I'm having the exact same issue using LineageOS.
It's already been 2 years, but since this thread is one of the first results on Google, I'll gladly add a solution.
Exact same problem for me, went through two screen repairs under warranty, and it would always come back a year later. No difference between Samsung OS and LineageOS, though I haven't tried rooting it.
Found on Ifixit: this issue is related to the AMOLED screen technology used by Samsung (among others). You can look it up, apparently there is a bad (?) voltage management in low brightness which worsen with time.
I could fix it with the "OLED Saver" application on Play Store. It works around this voltage management and allows you to reduce the brightness without the green flickering.
I still got white flashes after the installation, but not anymore the day after. I could even disable this application without the issue coming back.
I don't know what kind of magic cleanup this app performed, but it really is a (screen) life saver.
