Fingerprint sensor bug

[SantoshG14]

I recently bought s21 fe 5g , I did setup fingerprint and registered it. My friend just tried to use the fingerprint and it got unlocked without even his fingerprint got registered. Has anyone faced this issue?

can just tap you r f21 fe s back side like down the camera or middle of the phone...do you hear some tak tak or tap tap sound ?

Very rare incidence....re-register your finger prints.
In one of the finger print capture all of your fingers..

It is quite possible that ur friend used his finger while you in the background and it unlocked due to face recognition.
