Facing Issues in Samsung S21 FE 5G (SD888)

[nawaaz07]

I have been facing this issue in my Samsung S21 FE 5g snapdragon 888 processor variant.

When I try to unlock my phone then the half part in the lockscreen gets gray in color and at the same time the fingerprint sensor also doesn't recognize the finger and rather than that the fingerprint circle gets detect beside the lock button in screen. 

I

As you can see a white fingerprint detecting circle is appearing exactly at the middle part of the screen at right edge side.

t's been happening to my device since November and also tried by taking it to the Samsung Authorized service center but no use from there.

They told me to take a screen recording of the lockscreen but it Samsung devices can't record the screen in lockscreen and this issue comes frequently and at that time I don't have another smartphone to capture a video. But luckily today I got to take a video. 

So can anybody tell me why this is happening to my device

I am a S21FE SD888 user myself and this happens to my phone too.
This usually happens when you switch apps and lock the screen immediately or just close the app and then lock the phone immediately.
The only way to solve it is just type the passcode or the pattern that you have set as the security pin. The fingerprint sensor will then work fine.
Please tap on the three dots near my comment and tap "accept as a solution" if this works for you.

Have you tried formatting your device settings?
