8. Face ID
With the bezel-less OLED screen, there is no longer a Home button to unlock your iPhone X. Instead, the phone uses face-scanning tech known as Face ID. To do this, the phone uses the new front-facing True Depth camera system to automatically scan your face and verify your identity. It also uses an infrared camera, flood illuminator, dot projector, and various other sensors to authenticate the unique 3D features of your face and map your facial muscles.
