Oh but I do love my phone

[Undertoad]

I set up face unlocking.

I don't usually lock the phone, because most of the time I'm just at home and nobody cares.

But now I'm going into North Philly regularly, so I better get with the program.

So I set it up. You take a picture of your face using the front-facing camera, from a normal arm's reach away; and then when you want to unlock, you look at the phone, and it identifies your face as being the same as it pictured before, and unlocks the phone.

It works great.
