Weird issue with screen - Galaxy S II General

Hi guys,
Just a quick Q to see if anybody else has had this really weird issue. It's happened to me at random[AFAIK] and happened twice. When i'm playing music through the stock music app and press the "Power" button to turn the screen off, for about 2 seconds the phone shows the lockscreen, then everything is RED. That's not to say the whole screen is red, but the lockscreen text and everything is red and then the screen turns off. My lockscreen is the standard lockscreen(the crappy glass effect 1 that you swipe to the side to unlock) so the text at the bottom should be white and the notif bar should be normal, but it's all red.
Like I said, it's happened twice now and I was hoping it wasn't a screen problem!
Stock phone on O2. Latest O2 firmware installed.
Thanks.

I got the same problem once when the whole screen turned to be yellow for few seconds!
I'm on KE2 rooted and overclocked 1.5ghz

Purple in my case - fixed with a reboot. Had a suspicion it was software related, but no evidence...

Screen flickering

hi!
I recently bought a xperia and noticed that the screen is flickering when you turn off the automatic adjustment and turn the screen to maximum. Is this normal or should i return it? its very innoying. It's the light in the bottom of the screen that flickers.
I would return it. Mine does not do this, so I wouldnt consider this "normal"
seems that you have a defective retroillumination led... return it
yeah, definately not normal - mine doesn't have this issue
I also recently received my X1. I also note that the light of my screen flickers but only with certain software. It vibrates on the left when loading windows, and on the black bar in touchflo3d between the start menu and the clock ... I can't see if it is a hardware problem and therefore if I should get the guarantee

black spots on screen right when the phone is almost shut down...

I just noticed it today, when i woke up... Turned my phone on and off... And just when the samsung logo is gone, and the screen is not completely black and the back and menu button are still on. I could then see black dots on the screen, i tought it was something on top of it, but couldn't wipe it off...
I put it onder a light and saw nothing... very strange... What could this be??
I tried it again and again, and it was always the same...
Can someone try this in a dark room? to see if you have it too.
Could it be influencing my screen? I don't think i see it when my screen is turned on.
Thnx
I have seen those on 2 SGS2's.

Ah ok...Nothing to worry abouth than? you saw one without it too? It's only the 5 seconds when the phone is in this not complete black when the back and menu button are still on before shutting down completely.
But I don't know if this influences my screen or if it's just normal. What could it be?
Hey i've got an sgs2 with this similar problem of black spots on random part of the screen when i shut down my phone. it can be seen before the phone vibrates off. Is urs fixedd?? or sent for replacment??

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.

Thanks

[Q] Sudden screen black out but phone is on

I am having a problem with my Galaxy SI-9000 screen. It suddenly goes black and have to pull the battery to get back the screen. However when the screen is black the phone is still working because if I give a call the phone rings but the screen is black and can't see any thing? This started happening from yesterday, since then it has happened twice what may be the problem?
I am testing an application I have written(for battery use) and it is accessing the GPS and the MIC every one min.. can this have any relation with the sudden screen black outs?

A5 2016 sometimes won't wake up, screen flashes

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.
