Hey guys have you observed your phone screen having some flicker or glitch during unlocking? This only happens during unlock with dark mode off. Try this by opening your screen first then unlock with fingerprint or face and you will see some sudden flicker on screen but this happens fast but sometimes hurts my eyesight.

Maybe this could be software issue.

It still happens to my phone. Most of the time. Especially during calls.

Do you mean it goes black very fast like 0.1 sec before it unlocks?

Yes. Maybe for others it is okay but for me its not because i have a sensitive eyesight.

I just noticed it today when I read your post but only when unlocking with fingerprints, unlocking with face and PIN is normal, no flicker. (Brighten screen option is turned off during face unlock)

I searched online and I think its because of the fingerprint sensor, cause it set the brightness to max in the fingerprint scanner when scanning, then flickers black very fast to re-adjust the brightness on that area to match the whole screen brightness before unlocking.

Maybe. I had Galaxy A71 before but this one did not happen. Thanks for you answer.
