Always on display glitch

[Green_fl4mes]

I found this weird always on display glitch on my A71 that moves the fingerprint icon to the top left corner. This has only happened a few times and if you play you finger on the sensor the icon resets to its original position.

Hi, please go to settings >> biometrics & security >> fingerprints >> enter PIN/password >> show icon when screen is OFF >> select either of them (tap to show or never).

If issue persists, try clear cache and clear data for always on display.

Open Settings >> Apps >> Show System apps >> AlwaysOnDisplay >> Storage >> Clear cache and clear data.
