Yeah yeah yeah, I know, so many other similar threads... I’m not advocating returning the X. I’m not saying any other iPhone is overall better. But facts are facts. Forgetting evil twins and other lookalikes, the real problem with TouchID isn’t security. It’s speed. Face ID is slower and less convenient than Touch ID. Period dot. Since the iPhone 5S, I’ve trained myself to pick up the iPhone “thumb first”. This means that historically, the phone is already on it's way to being unlocked, or is already so, by the time I get it anywhere near my face. There were basically 3 variables in the unlock process... cleanliness/dryness of finger, cleanliness/dryness of the home button itself, and what kind of mood the iPhone itself was in on a given day. Yes, there were rare occasions where it didn’t work for some unknown reason. But the vast majority of unlock attempts were, for me, completed before I could even look at the phone. Face ID is great in theory. But there are apparently way more variables in the unlock process. Angle of your face. Height and angle of the phone. Quality/angle of the initial facial scans. All I know is I have gone from near instantaneous unlocks to often completely unsuccessful unlocks, something which happened with TouchID on only a very small handful of instances. I have had FAR more unsuccessful or highly delayed unlock attempts in 3 days of X ownership than I did with TouchID over the course of 4 years. I’m not returning the X, in the hopes that machine learning will eventually kick in and the unlock process will become as reliable and instantaneous as TouchID. But I’m not holding my breath. The big takeaway here is that in general, Touch ID rendered the phone ready to use before I was actually ready to use it, while FaceID has me ready to use the phone before the phone is ready. *EDIT* The opinions expressed above, while factual for me, are not necessarily facts for everyone.
