So my mom got her old Samsung galaxy a31 phone fixed and gave it to me,but after a while,I realised the fingerprint sensor is malfunctioning,I have it registered with my right and left thumb,but now,any fingerprint unlocks the phone,even my cousin and friends fingerprint work even though its only registered for mine,plus this display was replaced in Malaysia,which I think was a Samsung authorised shop although they did take the case that was on before,but I need why is the fingerprint sensor unlocking for anyone
