Apple iPhone X Camera Test

About an hour after taking my iPhone X out of its box, I'm bouncing up and down as high as I can on a trampoline, trying to see how FaceID works under, let's say, less than ideal circumstances. I'm eight feet in the air, sweating and grimacing, only half-paying attention to the phone as I try not to break my legs on impact. I grab the phone, hold it up to my face, and try to focus. The first time, FaceID works great. It unlocks virtually instantly, as soon as I fix my eyes upon the TrueDepth camera in the notch around the iPhone X's screen.
