I am facing this issue with my Samsung A50, when I lock or when the timeout occurs the phone doesn't unlock or touch, face unlock or anything doesn't work or appear on the screen as it becomes pitch black with everything working in backgound.
One thing to note I can hear notification sound and call ringtone after it goes black.
Things I tried:
Changing all settings with my Display like Brightness, Always-On display, Screen Timeout (Max timeout is 10 min in this phone), Battery mode (tried each of them).
Putting face Unlock so it can unlock the phone when it's blacked out.
Changing all different types of locks.
Changing the launcher.
Even factory reset+wipe the cache memory didn't work.
It's not in warranty.
I have to restart it every time to make the reappear the screen again.
Is it rooted ?

first i thought it was launcher pro's fault, but after changing launcher and rom release i'm pretty sure it's something else i haven't tracked down yet.
just after a reboot phone works as usual: screen lock runs after 30 seconds or by clicking the power button
after a while (days or even hours sometimes), the screen lock does not kick-in anymore: the screen just turns off and when you press the power button the phone is already unlocked.
i noticed that when the phone is in this "lock-bug" mode the notification led constantly shows a faint red light (you can barely notice it in the dark because it's really faint).
tested with:
launcher pro
go launcher
factory rom 2.21
blurless 2.34
I used to have the faint red light on after flashing a new rom.
It disapeared after I changed display setting to not automatic brightness.
It seems that the faint red light is the light sensor.
But I know nothing about your screen lock problem.
I have run into the same thing. I have not yet noticed the light, but I've had the screen lock stop working on my phone twice (I bought 3 phones 5 days ago for work). Like you, a simple reboot fixed the problem. I also tried toggling screen lock in the settings, and setting up a lock code, to see if the screen lock would start up. Both of my times, the first I noticed the issue was when I received a phone call and didn't have to swipe to answer, but that could have just been coincidence.
It isn't really a big deal for me or the employees, but it is a nuisance.
Happened to me as well, twice. First time it was just annoying that I had to reboot, second time it drained the s**t out of my battery in three hours.
So it's a bug allright.

same here.. it just stops working.. any fixes yet?
So I turn my N910c the notifications panel lock that can not lower the curtain ... When locking and unlocking the screen back to normal functioning without crashing.
I just restart and then back to catch the notifications panel only the first time, after locking and unlocking the screen returns to normal.
I've done wipe and remains the same.
My LG G5 recently stopped automatically turning the screen off despite the time settings. I first noticed the phone would warm up in my pocket, so I investigated further. Even though I attempted to work-around the issue by disabling lockscreen notifications, the screen will turn itself on whenever I get a notification then never turns off (doesn't even dim itself). First of all, I do not want my screen turning on for notifications, but additionally, I want the screen to timeout on its own. Any suggestions?
Hey everyone!
As the title say i'm facing a issue with my always on display.
I'll try to make it as simple as possible:
When I set the always on display to be always active it works flawlessly.
When I set the always on display to activate on tap (and last for 10 seconds according to the settings) it appears for roughly 3 seconds and then disappears for 3-4 and reappears flickering for 2-3 times sometimes showing the desktop wallpaper between each flicker.
Did anyone experience the same issue?
What I did to try and fix it was:
- tested both on battery and while charging
- factory reseted and then restored backup (which was stupid, that lead me to the second point)
- start in safe mode (to check whether it was an app causing troubles) but no such luck, problem still occurs.
- uninstalled "nice lock" apps
- changed some settings under the always on display tab
- cleared cache of the always on app
What you should know:
- I'm running android 9, not rooted and have nova launcher as default home
- After I factory reseted the phone I wanted to stop always on display from updating to test whether it was a new version issue but I forgot and didn't make it in time so I'm currently running the latest version
Does anyone have any idea as of why it's behaving like this?
edit: just wanna be a little more clear, flickering is not meant like a lightbulb it's more something like it turns off and back on after a delay (I'm sorry english is not my native language I can't really explain it any better)

i also experience the same.
this phone has many strange bugs.
when i restart my A70, tap to show always on display works for me for 2-3 times.
after 2-3 times working correctly, the bug starts.
after i tap the screen, it shows AOD for 2 seconds. then turns the screen off and then at the end of the 10th second, screen just flashes itself for the last time and turns off completely.
i think it is related to the fingerprint scanner.
because after i registered my fingerprints and turned on unlocking the screen by the FP reader, this bug ends.
after i tap the screen it shows both the clock and fingerprint icon at the bottom of the screen.
after 2 seconds fingerprint icon disappears. and the clock is continued to be shown until the end of 10th second.
but there is a minor issue, when the fingerprint icon disappears, the AOD screen brightness changes. dims or brighter slightly.
can you please try tap to show AOD, by enabling the fingerprint unlocking?
samsung ?

Hey! Thanks for the answer, I can confirm we have the exact same issue. I also have the same brightness issue you described
Anyway, I have always used fingerprint unlock though so I don't know what to answer you.. I only recently noticed the weird behavior. I did a couple things to test and I found out that enabling the "fingerprint" icon showing in the always on display seems to "fix" the issue of the flicker but not the one of the brightness change (after enabling it i've yet to see the problem occur), you should try it and let me know if you see any improvement. It's probably on samsung's end though and hopefully we get it fixed with android 10 or earlier
I'll take this chance to ask you another question; two weeks ago I received a software update and ever since that day I noticed my battery to be lasting waaaay less than it used to, did you update your phone as well? Did you notice a battery drain?
I have the issue both of you talking about.
hello, I had this same issue and what I did was turn the phone off, and booting it up while pressing "Volume Up", after entering a black screen with many options, I selected wipe cache. It has worked without a flaw since then. There's lots of bugs with this phone. I recently had a problem where the USB port will detect a device and "plugged and unplugged" it, making my phone unable to dim. Thankfully I was helpful.
Hi,
I recently clean flashed Pixel Experience 12 plus rom on my Oneplus 5T (dumpling).
(file: PixelExperience_Plus_dumpling-12.1-20220614-1354-OFFICIAL.zip , source : https://download.pixelexperience.org/dumpling )
After that I am facing a serious issue regarding the display.
After screen is locked (by pressing the power button or using tap to sleep feature or screen time out), it does not light up at the time and after unlocking. The screen remains black. But it does not mean that the display is gone or the phone is turned off. Phone works perfectly fine at that stage except the issue. The touch, vibration, sound effects,locking-unlocking (through fingerprint), taking screen shot, notification and call facility etc. works normally.
Sometimes the screen flashes for some millisecond if I try to unlock it repeatedly but it is visible only in the dark room.
To get rid of this state I have to boot the phone in recovery (Orangefox) mode then turn it on or force restart the phone (force restart does not work every time. When it does not work the boot screen also remains black)
Surprisingly, I do not face the problem in fastboot mode or recovery mode. Also when Always On Display is on, I don’t face the black screen issue.
I have followed instructions mentioned in this page https://telegra.ph/How-to-install-Pixel-Experience-11-25
and flashed firmware.zip (whose link is provided on the page) and PE12 plus rom .
Please help to resolve this issue and let me know if you need any further information.
Thank you..
I have got the same issue on my MI A2. after replace display I worked fine with pixel experience. and I moved to stock firmware. that is got the same problem. how to solve that issue?
