My fingerprint unlock stopped working.

Strangely enough it didn't stop working right away but after doing a diagnostic check (where everything is checked) this morning. I have the current  One UI 4.0beta since 10/25/2021 on my S21 Ultra

I deleted mine and readded them they now work much better. I suggest labeling each recorded print though. This makes it much easier to know which one the redo in the future. i.e. I do 2 right thumbs/ 2 left and I lable them as such.

I've read other folks with the issue, though not many.

I'd suggest what @RebootRenegade detailed ... to re-add them

I also have a glass screen protector on my S21 Ultra and my work phone is a Note20 Ultra. I had a little more issues with the Note but I am chalking that up to the smaller sensor in the phone 😂

Thanks...I deleted mine and couldn't add new ones until I went back to the diagnostic. Now all is fine! Thanks!

Same issue here. Fingerprint scanner is enabled in settings, yet it suddenly disabled itself.
Already reported.
