Green display Samsung A54

[Maneeha07]

This is exactly what I've been facing in my galaxy a54 for the last 6 days.

On lock screen, the display remains green and flickers too. But on home screen, its fine. Similarly whenever I have to unlock any app via fingerprint, it starts flickering and display turns green, otherwise its fine.

Why is it happening?

Requiring fingerprint, display is green and flickers too, also have a line in middle of the screen.

No fingerprint , display is fine.

Lock screen, display is green and it flickers too.

Home screen, display is fine

Has this occurred after a recent update?

[Maneeha07]

Yes exactly after security patch of may, one ui 6.1

Please attempt to remove all fingerprints and register them again. Subsequently, kindly verify if the issue has been resolved.

[Maneeha07]

Yes sure let me do it

If that doesn't work, then factory reset the phone and check again.
After a factory reset, if the issue still persists, then visiting the service center is the only option.

( Make sure to back up all your data before a factory reset )

I performed a factory reset too, but all in vein

There are two options then. The first is to wait for the upcoming update, which might solve the issue. The second is to visit the service center.
Many issues occur after some updates and are solved after a factory reset. If not, then the only option is to visit the service center.
Nowadays, many issues are faced by users after any updates.
UI 6.1 has too many flaws related to the UI.
