3 Face ID Swipe Up
This is for iPhone X/XS models only, but if you use Face ID there’s a brand new, hidden feature that you might really appreciate. As before, if Face ID fails to recognize you the first few times, the iPhone will bring up the passcode notification so you can type it in. However, in iOS 12, you can also swipe up on your screen. This will automatically restart Face ID to see if it can recognize you for the second round. It’s a great feature if you were at a bad angle or in a sudden glare and really want to try Face ID again.
