OnePlus announced the OnePlus 6T on Monday, the first phone coming to the U.S. with a fingerprint reader embedded inside the screen. It's one example of how Android makers are playing catch-up to Apple's Face ID technology.

Apple proved with Face ID on its new iPhones that facial recognition is the easiest and most secure way to unlock and make purchases with phones. You just need to look at the phone for a split second and it verifies you're the proper owner.
