Green stuck pixel on always on display + lock screen only - Samsung Galaxy A70 Questions & Answers

Like the title says, I've found a stuck pixel (green) on my phone but only when always on display is active.
As soon as I completely unlock my phone it disappears and starts working again. Could it be caused by a software issue?
I tried using several wallpapers for lockscreen and desktop (black, white, red color) and I am 100% that the pixel goes back to working fine after the unlock
I'll specify that the green pixel is visible on always on and on the lock screen (where I see notifications and pin unlock) and disappears right after
any ideas?
thanks in advance!

Yeah it sounds like a software issue.

Even though the thread is old. I have the same exact issue with my samsung galaxy a53. A green stuck pixel only shows when fingerprint icon is displayed.(lock screen/AOD). Was it fixed with software update?

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

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

Always on display icons?

For some odd reason I can only get notification icons on the AOD if I have a lock screen selected. I don't remember this always being the case. Anyone have icons show up with no lock screen selected?
Thanks

Same, I hadn't put 2 + 2 together and figured out why, but I had noticed I wasn't seeing the icons, only the LED flashes to indicate waiting notifications.
Would love to get them back without enabling a lockscreen.

I figured it out. If you have the lock screen set for 30 minutes instead of power button everytime you lock phone it works good.

Display issue with lock screen!

I have an issue with lock screen of google pixel 2 xl. My issue is, suppose my home screen image is while color and my lock screen color is black color. whenever I lock a phone. it does work properly but when I turn on the screen at that time my screen is showing some kind of flashing color of the home screen(white color) and after it turns to black color. So it is showing the tiny delay of real color in lock screen.!
I hope, it does not hardware issue.!
Does anybody face the same issue? Does anyone have a solution for this one?
