I bought an iphone 7 from our local phone shop a few months ago. Not the latest model, obviously, but probably quite adequate for my modest needs and not expensive in comparison with the latest models. The shopkeeper set it up for me and included what I think must have been a Face Unlock of some sort, because every time I looked at it, it unlocked.
At first, and in ignorance, I found this rather annoying, and somehow I managed to lose it, which I now find is even more annoying!
I have managed to get Touch ID to work OK, but it tends to stop working if I've been doing some DIY and my fingerprints have become worn, but I would like to get Face Unlock back again.
Googling for it says two things: Face Unlock isn't available on the I-Phone 7 (in which case what was unlocking my phone every time I looked at it?), and alternatively go to Settings>Face ID and Passcode etc, except that I don't get Face ID and Passcode, only Touch ID and Passcode.
I've tried searching the Apple Store for an App, but don't see anything that might be what I want.
So how do I get Face ID back to unlock my iphone, without having to eat humble pie and visit the shop again and get him to restore it?
