Almost every phone manufacturer is trying to develop a handset with a truly edge-to-edge display. Most end up with a small notch, but others are finding new and unusual ways to hide the front-facing camera. Oppo, for instance, has packed a tiny motorized mechanism into its brand new Find X flagship. At a glance, it looks like a regular phone with a 6.4-inch, 1080p display -- but as soon as you launch the camera app, the top section slides up to reveal a 25-megapixel selfie shooter and a dual-camera system on the back. Close the application and the cameras will automatically disappear again.
It uses this pop-up trick for face unlock, too, complete with iPhone X-style infrared depth detection (nicknamed O-Face -- no, really) to securely sign you in most any lighting condition. Other party tricks will seem familiar, too, including portrait lighting effects for both front and rear photos as well as Omoji, Oppo's take on Animoji.
