New Xiaomi Mi 9 Lite flashes on wake-up


Jan 9, 2021
The phone in question is with (QFCMIXM) Android 10, Xiaomi Mi 9 Lite.
The screen seems to flash bright color on wake up, after a certain amount of time after I lock it and leave it idle (10 seconds). Then I pick it up and unlock, the same as in video happens.
It does not occur if phone was previously used, and it didn't go into what I call deeper sleep(probably turning off the screen completly?)
This issue is with those newer updates, didn't happen before, although might be coincidence.
Your opinions? Did it occur with someone else?
Thanks in advance.
