USB device unlock in A54 lock screen

[Marimuthuofl]

Why my A54 always shows like this. To use USB device, unlock your phone.

It is normal or not?

It's Normal.
It is Due To Knox Security And Verification.

Use dark plain black wallpaper. Then see the display.

Normally A54 display have grainy effect. Why?
I checked all A54 model have same effect why? (In plain black colorwallpaper)
Display problem or software problem?

It's May Be Display Issue

[Marimuthuofl]

Service center said it's not a display issue. Customer care also avoid the complaint. Are you facing this issue?

Enable fingerprint unlock, then change wallpaper in pain dark black then see in the dark room the display getting grainy flickering effect?
Please try and inform me🙏?

Actually,I Don't Have Samsung Galaxy A54 5g But I Got To Know That Many Users Are Facing This Issue Regarding Display Grain

[Marimuthuofl]

Yes I complained lot to samsung through service center. But they said no problem in your mobile.
There is no solution for this issue.

I am getting the same grainy effect effect like flickering on my a34 since i have turned off youtube search recommendation and i use dark theme whenever i go to youtube and click on search if you see carefully you see the gray screen on my display flickering idk why it happens

[Marimuthuofl]

I think display quality worst in A54 and A34. Customer care not accept and not giving solution. They avoid the complaint. Don't buy samsung again worst service and mobile.
