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 never had contact with police or airport staff where they wanted me to unlock my phone. And I doubt that this will happen anytime soon if ever.
It’s not a problem, until it is a problem.
“It hasn’t happened yet” is not a valid basis for making decisions.
It probably heavily depends on where you are from. I guess you are from the US?
What makes you think so?
Because generally the TSA in Yankland are overly aggressive, but to be fair it can happen anywhere and here in the UK if they snag you into the backroom and want to search your phone you’re screwed either way since they, can.
