How are different users supposed to use the phone? There are root (devel-su), owner, and then other users (without the stores?). I understand CLI users better.
I thought about using the phone regularly as a user other than the owner but that seems to be slightly inconvenient without the stores.
Also, setting fingerprints for the owner and a user, and then switching between the two gets eventually the fingerprints mixed and both the owner and the user can unlock the phone, after the initial PIN upon login(?), with the both fingerprints. I have installed the update from last evening and tested this using thumb and index fingerprints for different users.
