Face ID is by far my favorite feature of my iPhone X. I was expecting the camera to be the number one feature. Don’t get me wrong, camera is fantastic. As good as I expected and then some. But Face ID just blew me away. I was always having issues with Touch ID. Whenever I have sweaty hands, or sometimes just randomly it would fail. Since iPhone X I almost never have to actually enter the lock code. It just works. And in rare cases it fails it works on the second try when I retry it “properly”, fixing the usually obvious reason it failed, e.g. not facing it right etc.
