Samsung Galaxy S23 ultra 
All of a sudden my finger print sensor stopped working!!
I get error messages ' Cover the entire fingerprint sensor'.
Did a quick sensor check using *#0*#, got fail on the following checks.

DBIAS_CAPSENSE_CHECK - FAIL
DBIAS_TUNED_DBIAS_VOLTAGE - FAIL

Very disappointed, expensive phone and relatively new

Any Samsung expert, please advise

I got a similar issue with my S21.

Woke up this morning, when i checked my phone it said on the lockscreen that the fingerprint data was corrupted. After that i just cant use the sensor.

I tried:

● restarting the phone,

● rebooting in safe mode,

● updating the system, 

● force stopping and cleaning all data on the biometrics app,

● deleting my fingerprints and trying to add them again.

When i do try to add my fingerprints again, it just says "Fingerprint sensor isn't working"

● using the members app to test the sensor, but it only lets you test it if you have fingerprints saved. And since i deleted mine a few minutes before trying it, i'm just stuck in a loop.

● I also tried the *#0*# code and the results are as follows:

Is there any way i can fix this?

Is this maybe a hardware failure?

I love my phone, it's a S21 that's been with me for over 2 years and i really don't plan on switching it to a new model just because of one sensor...
