Don’t ever hand your phone to the cops
(www.theverge.com)
This is a most excellent place for technology news and articles.
Pro tip, if you suspect the police are going to take your phone, turn it off. As far as I am aware, finger print and face id do not work on initial startup and they can't compel you to enter your pin without a warrant.
Better yet: don't use biometrics. My phone has face recognition for unlocking, but I better stick to a PIN/PASSWORD.
Or better yet just don't use a phone at all! Can't make you unlock what you don't have!
