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.
Should it arrive to that they can still seize your devices and also force you to unlock your devices biometrics or patterns/passwords regardless. I wouldn’t trust law enforcements in this regard.
