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.
A vocal bunch bitched about this, but I’ve had the 6+7+8 Pro pixels (with under-screen sensors) and I’ve never had an issue. Family (who I hand-down when I upgrade) have never complained either. I use my phone near constantly and unlock actually hundreds of times a day. 🤷♂️
