@santosshishonge did you try the possible solutions listed in the above answer?

did it previously work?

did you place a screen protector on it when it was working. Most tempered glass are not fingerprint compatible (too thick). The ceramic ones are, but I personally don't like any of them as they are to brittle and crack easily. The soft ones are best IMHO and they are compatible.

@yeabsirage73720 check in your settings to see if the fingerprint sensor still shows. Something like this video will show you how to set it up. If you can't, or if your sensor does no longer show in settings, then you will have to consider replacing the fingerprint reader. For the guides, check this site It does have the fingerprint reader guide listed.

While you work on your A21s, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
