If I were a breaking bad meth dealer and had all my buyers as contacts on that phone and all my incriminating chats, I wouldn't use biometrics to unlock it. But I'm not a meth dealer (and I'm not just saying that because that's what a meth dealer would say).
There is a spectrum of convenience vs. security. It depends on where you sit. I'm okay with the fingerprint, wouldn't go for the face.
Doesn't Android have the panic/cop switch where you force password over biometrics unlocking? It's not a 100% failsafe but it is a start.
I assure you. I'm not a meth dealer. Really. I don't know what else to tell you!
Thanks for answering my question.
