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.
I have no idea what you're talking about, and frankly I don't think you know what you're talking about either. FaceID is not even available on the 8, and the 8 hasn't shipped to apple stores yet so even if it was you couldn't have tried one. The iPhone X has multiple systems required for 3D mapping of your face that FaceID requires to function. Plus, each time it reads your face it gets better at reading your face, including your facial hair growth. So, I'd say that the 10 is indeed "super advanced and knows how your facial hair grows."
