I faced that before.
Most likely should be the factors below
1. Some app is sending/receiving data so screen is on for notification
2. Downloaded some weird themes for launcher/messaging software, even u do not use them, it can cause the screen flashing problem.
3. Problem with third party lockscreen software, either wrongly configure or has bug

BUG: screen lock does not kick in

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.

White screen when i lock phone!

Hi everyone!
I've installed Myn's Warm Donut and it works, but when i lock the phone with power button i have white screen! I've tried all panels! What can i do?
Thanks for the answer!
When you lock or when you turn the screen on again?
EVERY android kernel has a bug with screen wake up. If, in your case that happens, its perfectly normal, that white screen stays for like only a second and then android lock screen shows up. Press menu key and ur device will unlock. Sometimes that white screen stays, in that case just press Menu color again if that white screen still stays, you need to change the panel. Its impossible that white screen stays for infinite time. Mind to have a radio version greater than 1.65

Colours messed up?
white screen keeps there FOREVER?
Its time to change panel, try using Type 1 first, later try type 2 and type 3 is for exceptional cases
Every kaiser device has different panel type. Mine, HTC TyTn II KAIS130 has panel type 1 and another guy over here has same device he's using Panel 1 too. Warbyte has KAIS130 as well but he's using Panel 2. Its you who figure out that THIS panel is not working fine, lets try another. At maximum u understand it after two tries. And mostly you get a fine screen with fine colours in first try.
Only CHANGE panel if that white gibberish screen stays on for ever.

Disable Location feature, disable GPS Satellites, set Screen brightness to minimum. Keep Wifi off, disable Automatic sync, keep your memory clean and use a task manager, use 2G mode if you are not using 3G. Disable Data connection and enable it only when needed

Screen starts to glow on it's own???

Hi,
I don't know what's going on with the screen of my one-v...
well I press lock button, so screen goes dark, but after a while it lights up for few seconds showing me lock screen... then it goes dark, and after few second it does it again.
after 2 times it stops, but it is annoying when you put phone on the desk, that it glows so you start to think about coming call or text.
what's going on?
lolsss..
haunted maybe

haha well hopefully not
I thought at beginning that it could be caused because of apz running in background but I have double checked - there are not any

have you tried factory resetting?
Are you using an app like Keep Screen?
My friend had a similar problem when she used the Keep Screen app.
Have you received an update?
Try using another locker like GO Locker or Magic Locker. Inform if it happens again.
strange thing, but it magically stopped happening
That may due to your brightness settings which is set to "Automatic" by default.
well it was too early for me to say that problem is gone... it happens again today ;/
I have fixed level of brightness, no apps except battery life working in background... all newest updates installed.
any ideas?

LG G3 screen slowly turning white when screen is turned on

Hello, so I am experiencing a huge pain in my butt with my LG G3, the issue is that whenever I press the power on button to turn the screen on my screensaver pops up and looks completely fine, after about 5 seconds a white shadow starts to appear in the background and slowly starts to make certain parts of my screen invisible, but as soon as a lock my phone and turn the screen on its gone but the process starts again. May be a possible led problem or something else? I would appreciate any help I can get before I go and take the phone back to Verizon and see what they say.
What screen saver are u using? Have you tried hard reseting the phone?

Just a normal picture from my gallery nothing extravagant or anything, it's strange there are like dark streaks going down my screen, I cannot capture it on a screenshot so I'd have to post a picture of it.

Hello,
I have exactly the same problem. I am able to use the phone in all his features, but the display presents stripes of shadow white. These shadows disappears when phone gets locked and appears when unlocking after few seconds. How did you solve? Will the guarantee cover this problem?

Always on display "flickering" when activated (on tap)

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.
