Having a beard doesn’t mean it wont work
Cool, but the last time I tired it, it forgeted up a good 80% of the time because of it.
I had gone to an apple store to get my 6 looked at after the home button got stuck, and the sales person kept trying to push the 8 on me saying that the facial recognition would be the next big thing. I asked for a demo and they tried to map my face. It didn't work out and I'm still skeptical.
So yeah, unless the 10 is super advanced and knows how my facial hair grows on a weekly basis, I'm not convinced. Im still not convinced about the finger print lock.
