Screen flickering problem

Hi guys, suddenly i'm having this problem with my phone i'll let you the link to the video so you can see what i'm talking about- This is happenig just with the screen off when i missd the fingerprint or when i shut the phone off. I alrady tried other roms (i'm at xiaomi.eu stable) and flash it with miflash to global stable. The problem is always gone for a while after flashing but hours later even a day later it happend again and then never goes. It has to be hardware problem but i don't knoiw what could be, i don't want to replace de screen until i'm sure because once ii's unlocked with the screen on and i'm using it never shows a problem. I hope you can help me

Dang it. I'm experiencing the same issue for the past few days with my Global ver. Mi8.
Any solutions?
Any chance you installed "Dark Mod" or a similar MIUI Theme ?
It's probably a theme problem, had a similar bug when I installed a dark theme. Try restarting your device and then apply the default theme.
Just when I was about to go to the service centre, my phone becomes normal. How about you guys?
Have you try different rom?
Try to install custom kernel to resolve your screen flickering.

I have a similar problem. The screen, sometimes, when i try to turn it on, flashes and turn off again. When trying again it works.

This is exactly my problem, too. Did you solve it yet? I'm on newest global stable, no root and default theme.
Turn off auto brightness and turn upp brightness until it stop flickering.
You can try the app oled saver.
If the issue persists irregardless of brightness settings it's obviously a theme issue

im on screen flickering problem when phone going to sleep/lock
with your guide the flicker gone
thanks
The problem persists even though with oled saver installed. Is it software or hardware problem?
Hi
Can you try this
Go to Settings >> More Tab >> About device.
Find "Build number" and click 6 times fast on it.
You will then get the message saying: "You are now a developer"
Come back to Home Screen, and then go back to Settings >> More Tab >> Now you will see the "Developer Options"
Now go to Developer options >> Drawing Section or Rendering Section >> Find "Turn off hardware overlays" or "disable hardware overlays" >> This will force the phone to always use GPU for screen compositing

Did you install any custom miui theme?
My girlfriend had the same issue on her Mi 8, and it became so bad that the phone would just flicker and not show anything on the screen, even after restoring factory settings. She brought it to a Xiaomi service center, and after two weeks she got it back with no issues, the receipt they gave her mentioned a firmware update. Unfortunately, the phone came with an older MIUI version, and when it automatically updated to version 10.2.2 the flickering screen came back. We updated to 10.2.3 but the problem it still there. At least now the phone can be unlocked and used normally.
try this one
my mi 8 happened to have the same problem. it flickers every time I unlock and shut down my phone. I was about to repair it, but suddenly the flickers have gone. all I did was turn up the brightness somewhere around 50-70%. hope it helps!
dears, I have a worse variant of this problem: in my case, when the phone does not recognize the fingerprint. the screen blinks and then the phone turn off.
Have someone noticed that?
Here is the problem that i'm facing. Qlmost every time i plug my phone to the charger the screen start flickering, it even continue to flicker when i unplug it. Any advice?

Redmi K20 Pro Lock Screen Notification

So I purchased the new REDMI K20 Pro last week after going through a lot of reviews online. I love the phone and coming from a former Oneplus user is something. However I am having a certain issue regarding the Lock Screen Notification and I am at my wits end to resolve this.
Ever since I have purchased and setup the phone, I have been having some problems with my Lock Screen Notifications. The phone screen automatically lights up whenever I receive any notifications like whatsapp or gmail. This is awfully irritating as often I am driving or in meetings and it distracts me constantly. I have tried everything, tried looking into the phone settings and checking the notification settings but I can't get the phone to stop lighting up. On my Oneplus, I would receive the notification, the phone would buzz and the notification would appear on the lock screen but the screen wouldn't light up.
Is there a way to stop this? Am I missing something? Please help!
V
Settings->Lock screen & password->Wake Lock screen for notifications

Screen comes on randomly

Hi the phone lock screen keeps coming on without warning and it isn't related to getting any notifications. I've turned off double tap to wake screen doesn't make a difference. Any ideas?
I had same issue with my 7 plus, i solved the problem disabling "lift to check phone" gesture from settings -> system -> gestures

Question I keep getting lock screen notifications even if I turn on do not disturb mode

This is my first post. So, sorry for my inexperience here.
Device: Redmi Note 10 Pro
Software: MIUI 14.0.2 Global (TKFMIXM)
I just upgraded MIUI to 14 but I noticed this still persists.
In MIUI 13 version and MIUI 14 version that I just switched to, I get notification animation when the phone is locked even though the do not disturb mode is on.
The always-on display feature (for 10 seconds) and notification animation are on. There is no vibration or sound, but the phone's screen turns on and the notification animation plays. Turning off the lock screen notification animation every time is not very convenient. I have problems when I need to focus while studying.
Is there a setting or a way to prevent this? If there is nothing I can do, who should I report it to? I was not having such a problem on my Mi 6 (MIUI 12 Beta eu) device that I used before.
