Fingerprint scanner not working (S20 Ultra)

[S20userdb]

Help! My phone's been having fingerprint issues. It suddenly stops recognizing fingerprints. I can't also re-register since it doesn't pass 0%. I tried restarting, wipe cached partition, soft reset. I also did hard reset which worked for a while and then stopped recognizing again. Sometimes it works but most of the time no.

I also tried the fingerprint test on the diagnostics where all passed except the BGE_CAL_CHECK which is in "dash".

do you have a tempered glass on it?

[S20userdb]

Yes before, and I removed it. It works for a while and then gone. Same scenario when I re-install the tempered glass.

[Vinything]

[S20userdb]

yes.

Hey man, by any chance did you solve the issue?
Mine slowly stopped working over the past few days.. Nothing I try is working. I have not hard-reset yet though, that's my last option. 

I have the same problem as you with the BGE_CAL_CHECK coming up blank and everything else appearing normal... hope yours is fixed!
