Galaxy S5 G900F klte with LineageOS/eOS (Android 11) TWRP and Magisk Root.
The Screen works fine after booting the device. But:
- after the Screen Time out starts - the screen stays black (sometimes flickers a bit when pushing power button)
- also if i manual turn off the screen with i.e. pushing the power button - the screen stays black (sometimes flickers a bit when pushing power button)
Rebooting or taking battery out and back in doesn't help most of the time to get the screen back - and after the first screen time out / turning off screen manually it stays black anyway.
So at the moment I can only use the phone at home with my laptop (with scrcpy ).
I don't think it is a Hardware problem because when I boot into TWRP the screen works fine - for testing purposes i stayed for 2 days in TWRP and the screen came always back to life after every screen time out during the whole time.
Also the touch still works even if the display is black - when i see the screen on scrcpy i can see it functions normal when i touch around on the display.
I also noticed that the screen comes often back alive when i first start scrcpy with the --turn-screen-off flag and then push the home button 1 or more times on the phone)
Any suggestions how to fix that?
Is there maybe a graphics driver i could disable/change/switch in the development options?

Last night my XDA Mini S froze while using PIE, so I did a soft reset, put the phone down and went to sleep. Noticed this morning that it's stuck at the Windows Mobile splash screen - still in Landscape mode which is what I was using when PIE froze. Done another soft reset, same problem. My LEDs are flashing as usual, one green and the Bluetooth one.
Any ideas?
Thanks
Ok, it started working for some reason - but I noticed when it got to my today screen that my NotesToday plugin wasn't there. I went into Settings > Today > Items, and NotesToday was ticked. I unticked it, clicked OK, then re-ticked it and it showed up again on my today screen. Fine. However now everytime I press the power button to come out of sleep mode, my Today screen flashed up fine for about 0.5 sec, then flashed white for a millisecond, then comes up fine EXCEPT the whole "top" bar (i.e. the part of the screen with Start button, clock, signal strength, etc) stays solid white, and I can't see any of those icons. Rest of the screen is fine. If I click Unlock, the whole screen is fine after that.
Help!
I had a similar problem with a different part of the screen staying white after coming out of hibernate (the O2 active UI sidepanel)...Hard reset fixed it and the problem hasn't returned (although I don't use the O2 UI now...)
If your device freezes on the Windows loading screen, then soft reset it and while it is loading the next time, press one of the hardware buttons, such as the D-pad or the green or red phone buttons, continually as it loads. This should keep the lights behind the buttons turned on, and it should load Windows without a problem.
Had the same error on my phone, I think it tries to hibernate as it loads Windows or something equally stupid. Pressing a button continually prevents this and allows it to load normally.
Hi,
I experienced today a strange behavior:
I used my nook, turn off wifi, let it in my bag for 1 or 2 hours and when i tried to wake it the screen didn't turn on.
At first i though it was SOD but when i looked closer to the screen there was something on it, it was the CM7 boot logo (the tony hawks droid
The logo was not very visible, most like old "ghost image" on CRT screen when he same image is displayed for long periods of time.
I should have taken a photo, i will if it reproduce.
Kinda sounds like it was rebooting without turning on the backlight. Could you see the arrow circling? I've had "n" turn on the backlight with no image, but tapping power turns off the backlight, then tapping it again turns the screen on properly.
Sounds like somebody's state machine has a leak...
i will never know (i pressed power 8s, if it was booting, i just stopped it)
So I managed to drop my phone a couple of weeks ago and crack the screen. The screen itself has remained fully functional despite a couple of purple lines down it and progressively worse flickering. It;s gradually started becoming more unresponsive and tonight it seems to have had enough. The stay on screen still display the time and if I press the lock key it will show me my lock screen and my notifications, I can swipe and remove these and if drag them down to read them further.
However, when I actually unlock my phone to go to my home screen, the phone screen goes black - I know the phone has unlocked because I can hear the sound effects when I press apps but everything remains black and I can't get the screen to come alive again until I lock the phone. If I double tap the home button, it will quick launch my camera and that works. So essentially the screen still works but won't show me my home screen or any apps (apart from camera), it's essentially blacked out until I lock it again.
I'm getting it repaired but am not able to do so for a few days. Any ideas how I can bring the screen back to life when I unlock the phone? I tried restarting a few times, leaving it turned off for a while and emergency mode - none of which worked.
My phone's display as of 3 or so weeks ago has stopped working correctly. It only displays colorful flashes if I press the power button, or just a black screen. I can feel the phones vibrations and unlock it, it still gets notifications as well when it's on. How do I fix this problem?
Hello guys, my Nokia 6.1 Plus has developed a weird problem. When I turn on the phone the screen lights up as normal, displaying the androidone logo followed by the NOKIA logo before proceeding to the homescreen where it operates as normal. However, when I press the power button to turn the display off or when the display times out and goes off it doesn't wake up. It remains dark when I double tap on the screen or when I press the power button. The screen turns on but remains dark as I can feel it vibrate and respond to touch when I touch anywhere on the screen. I basically have to restart the phone to get it working again. The phone is basically unusable as I can't have the screen stay on all the time for me to use it.
What might be causing the problem and what can I do to remedy it?
Try to backup your important data and perform a factory reset.
May b it's hardware problem
