Oppo’s Bubble is a thin circular screen for taking selfies with the rear camera

Oppo has launched a new smartphone accessory that makes it easy to take selfies using your smartphone’s rear cameras which have better sensors than the front cameras. The Bubble offers similar functionality to where recently announced Insta360 Snap and a screen that provides the camera’s controls so you can take better pictures, including remote controls and a shutter button. What sets the Bubble apart is its compact design, wireless connectivity up to about 33 feet, and, unfortunately, device connectivity.

The Oppo Bubble is available in China for 499 yuan, or about $73, but the company has not confirmed whether the accessory will be released globally. It has a round AMOLED screen with a 550mAh battery, but it is only seven millimeters thick. The company didn’t comment on the Bubble’s battery life, but it should be charged via the USB-C port on the bottom instead of wirelessly when plugged into the back of the phone.

Some Oppo devices support wireless charging, but the company hasn’t released anything with magnetic rings for attaching devices. To attach the Bubble to an Oppo phone, you need to add a magnet. The screen can also be attached directly to devices with integrated magnets such as iPhones and the latest Pixel phones, but Oppo has only made the Bubble compatible with its smaller devices including the Reno 14, 15, and 16, as well as the Find X8, X9, X9 Pro, and X9 Ultra, through the accompanying mobile app. The company has not announced plans to expand Bubble’s compatibility to third-party devices.
