Oppo’s Bubble is a thin round screen for taking rear camera selfies

Oppo launched the Bubble, a 7mm-thick round AMOLED accessory for taking selfies with the rear camera.

It adds a live preview, shutter controls, wireless use up to about 33 feet, and a 550mAh battery.

The Bubble costs 499 yuan in China and currently works with select Oppo phones, plus magnet-equipped iPhones and recent Pixel models.

No global release has been confirmed, and limited compatibility may slow adoption.
