OPPO's Magnetic Rear Display Accessory Aims to Replace Front-Facing Cameras

OPPO launched the Bubble, a magnetic circular display that clips to the back of compatible phones to let users shoot selfies with the main rear camera—typically higher quality than front sensors. Debuted May 25 with the Reno16 series in China, the accessory shows a live preview on its small OLED screen and supports remote shooting. The magnetic mount avoids altering the phone itself.
