There is no extra step. That makes it sound like some process. All you do is swipe up. The phone is unlocked instantly just by looking at it. It’s just as fast if not faster than Touch ID. I have concerns for people that find this difficult. You swipe up to get to the Home Screen no matter what you’re doing, so it’s not like this gesture is uncommon. You use it frequently on the Face ID iPhones.
Kind of surprised to read this. I've heard tons of complaints on that extra step, compared to like the Pixel 4 FaceID, you state at the phone, and immediately goes to the home screen, no extra step of swiping up before you can get to the home screen.
There's a popular JB tweak to eliminate that extra step to swipe up.
Go on iPhone fan forums, it's a popular nag or minor complaint
