The fingerprint sensor on my S20 FE 5G is not working. Whenever I use it, it says 'Keep your finger on the sensor a little longer'. I have tried using it from the lock screen, add new fingerprint screen and diagnostics, but the error is same everywhere.
I am also facing this issue since May 2023... I think this is seems to be hardware issue... if not purposefully company is making update which can damage this sensor...
