OPPO has unveiled the Bubble, a magnetic circular display that attaches to the back of compatible smartphones. The 1.73-inch AMOLED screen can serve as a rear-camera viewfinder for selfies, display wallpapers, live photos and videos, and even act as a remote camera shutter with live preview support from up to 10 meters away.
It can also be used as a standalone accessory attached to bags or clothing. Featuring a 550mAh battery, IP54 protection and a lightweight 27.5g design, the Bubble is priced at around $75 in China. While it supports several OPPO and OnePlus devices, there are currently no plans for a global launch.
