in display fingerprint problem

[Android Central Question]

Hey guys, I am new to Android Central so consider me as a newbie. I recently changed the glass of samsung A50 but after the glass change the finger print is not no longer working it just displays a message hold your finger bit longer. I don't understand I have only changed the glass the display is stock and I carefully placed the fingerprint scanner in a tissue so it can't catch any dust etc and I had checked the whole phone properly but I didn't find any problem I just get the same problem whenever I change the glass of any phone which consists of a in display fingerprint sensor. Can you please tell me the problem and guide me through

 

[me just saying]

did you delete your old fingerprint and create a new one? if not, give that a try.
