Fingerprint sensor not working???

[puddin143]

I had to replace my screen on my Galaxy A70 and now the fingerprint sensor doesn't work. It gets to 21% then stops. Does anyone have any idea what is the issue or better yet, how to fix it?? I'm losing my marbles trying to figure it out...

Sounds like whoever replaced the screen, didn't do it properly. 

Take it back to the repair shop.

Hi, Restart the phone and set up the Fingerprint once more.

If still giving issues you may have to take it back to the store who did the repair and let them fix the issue.
