iPhone 8.
This conversation is over. Im not sure why you want to question a personal experience.
If it worked most the time, Id enjoy it more. Apparently working with your hands is a against the rules.
I’m just trying to understand what you’re talking about precisely, because your personal experience doesn’t really make sense to me so far. Maybe you were talking about Samsung’s Galaxy S8 Face recogniztion system? You have the right to have an opinion on a feature but atleast have some credibility when sharing your experience on it, maybe talk about the right brand or product.
Update from Apple about the « failed » on stage Face ID demonstration, turns out Face ID just did its job.
Tonight, I was able to contact Apple. After examining the logs of the demo iPhone X, they now know exactly what went down. Turns out my first theory in this story was wrong--but my first UPDATE theory above was correct: "People were handling the device for stage demo ahead of time," says a rep, "and didn't realize Face ID was trying to authenticate their face. After failing a number of times, because they weren't Craig, the iPhone did what it was designed to do, which was to require his passcode." In other words, "Face ID worked as it was designed to."
