TL;DR
- Strings in the latest Android 15 beta suggest the OS can automatically delete biometrics that aren’t working well.
- Android will delete your face or fingerprint unlock when they aren’t working well and then prompt you to set them up again.
- We don’t know how the OS determines when a biometric isn’t working well or if this feature is even live yet in the latest Android 15 beta, though.
I swear it did this on 13 and 14, too.
What ROM? Can’t be a pixel
Not the Pixel, no; I’ve had it happen on my previous phone like twice. It was the dual screen LG V600.
