Just moved to an iPhone X because my iPhone 7 broke
How could anyone want to move back to Touch ID? I was skeptical... but using it is a revelation.
Touch ID failed on me waaaay more than Face ID. And FaceID is way faster than I was expecting.
While Face ID works most of the time for me, I still find it more frustrating than my old fingerprint sensor phones did (although I never had an iPhone with a fingerprint sensor, maybe the android phones I used in the past were better than them, not sure).
Even after retraining and scanning two separate angles of my face and giving the XS Max time to learn my face better, I still get unlock failures for having the phone too far away, too close, not at the right angle, or if I just wake up and my face is squinting or grimacing. I don't grow and shave a beard, don't wear hats, my weight doesn't fluctuate, etc. I miss more than I thought I would being able to unlock my phone while it's sitting flat on a table to the side of me (without having to pick it up or press the button and awkwardly position my face over it). I find myself having to type in my password more than I ever did with fingerprint sensors on my past phones (even shitty fingerprint sensors like the old Note 4).
Even when it does work as intended I still find the need to pick up the phone and swipe up to take longer than just tapping a fingerprint sensor used to be.
And I'm not saying it fails like 50, 75, or even 90% of the time, it does works most of it the time, it's just a few more percentages more than a fingerprint sensor that makes the difference between never having to think about it, and having it not work at least once a day.
I haven't decided yet if it's a big enough annoyance (along with some of the other issues I've had with my iPhone) for me to sell the phone and go with either an iPhone 8 or just go back to Android and use the extra money on an iPad, but I definitely don't think I'll be buying another phone where Face ID is the only option.
