Amoled Screen white flash - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hello, when I unlock my phone the screen sometimes flashes White for 0.5 second. Is it problem with my device or it is common? Mi 9t pro

Do you use the fingerprint unlock?

Yes, but it happens even I just turn it on with button

Hey, mi9t pro here (2020 jan. bought). I have exactly the same issue. 1 out of like 10 or 20 unlocks the screen flashes for a split second. Haven't found a solution since then :/

I see a white flash using YouTube when switch from portrait mode to landscape mode.

Automatically lower brightness

I have k 20 pro Indian variant, full stock, no root ,etc, i have a problem, my screen brightness automatically lowers whenever i exit the game mode and sometimes randomly too ,i have disabled auto brightness option as well as DC dimming option;
I also noticed that the screen is on warmer side, i have nokia 7 plus and i opened white wall paper on both the devices, and k20 pro shows warmer image, and nokia 7 plus is showing a proper white image, i have tried all 2 colour modes in display settings, but its still showing warmer image.
I tried hard reset also.
Can anyone tell is these things are hardware fault or its just software problem with everybody device.
K20 pro, MIUI global 10.3.3.0 stable
I assume it should be a hardware related issue.
As far as I am concerned, brightness change could be related to software. For me it happens since I installed Xiaomi EU beta. Of course this shouldn't even happen in your situation but who knows.
Warmer images, as Anand_theGeek says, this should be related to hardware problem.
Same happens to me. This is a F******g sh****t
It is a problem with EU beta
I also noticed that front camera is making face red while clicking selfie, if i cover my face then camera is showing actual colours, but when it recognizes face in the frame it automatically turns the face red, i also disabled all beauty footers but seems there is something wrong with camera software, because gcam port is not showing red face in front camera, can anybody confirm if they are also facing this issue.

Same here, after 2 days I suddenly noticed the display has a rather warmer white tint.
Compared it with my Poco, and there is a substantial difference between the two phones, whereas the MI 9T PRO, almost has a yellowish white.
I did noticed that, when rebooting, the display is "normal" for a second,and then turns to yellowish.
Still on stock rom, bootloader locked.
Edit: it is gone, suddenly the whites on my screen returned to normal. I was already thinking it had something to do with the automatic brightness combined with the Night Mode settings.
you guys using auto brightness mode ?

Same problem here. Sometimes even if I use cold colours in display settings, I get verey very yellowish whites. And sometimes not. Using increased cotrast is the same thing
I'm not using DC Dimming, auto brightness, reading/night mode. It is very strange..
Still no solution for this??

Pocket mode issue

I have a Mi 9T Pro with MIUI 11.0.3.0 Since I updated, I have problem with pocket mode. When I wanna unlock my phone with fingerprint scanner on turned off screen (It's important), I usually get the "Don't cover the earphone area" message for 2 sec, and after this disappears. Today I realised that It happens every time when I turn off the screeen in a lighter place or room, and after unlock in a dark or darker place. Can somebody check this problem on his/her own phone? I'm interested in about this is my own problem or It's a MIUI 11 issue.
There aren't any TG or screen protector on the phone.
I have the same problem. To bypass i have disable pocket mode from ambient display setting. Hop xiaomi fixes it
Turn off pocket mode in Redmi K20 Pro/ Xiaomi Mi 9T Pro
1) Go to Setting
2) Scroll and search for keyword *Always-on display and lock screen*
3) In this section scroll down until you find pocket mode..turn it off.
It works for me..try it
It happens of you are in a dark room and too close to the earpiece with you body or objects (to me it happens a lot in the bed since I like to stay under the sheets)

I need help with screen

I just bought a replacement screen for my mi 8 but it has no display. I believe the screen is working because there is a display when booting (I can see splash screen) but after the splash screen the screen goes dark again. the fastboot also visible. do I need certain firmware for this screen?
update:
I have made it work but with only miui 10 8.6.18. if I try to update 1 version higher the screen goes black again.. does anyone know what the culprit could be?

OnePlus 7 pro screen flickering (kind of)

Hello everyone there, I've bought a used OnePlus 7 pro a few days ago. But I'm having an issue with it.
Whenever I turn brightness to full, screen starts becoming small and big and small and big. I've tried turning adaptive brightness on and off, removing the screen protector, and rebooting into safe mode but nothing works.
I wanna know if the problem is with software or my phone's screen is damaged?
If this problem is with the screen then how the screen recorder is able capture it?
