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

Oppo launched a new smartphone accessory called the Bubble, designed to facilitate rear camera selfies by offering a live preview screen, remote controls, and a shutter button. It competes with the Insta360 Snap but features a thinner design and wireless capabilities up to 33 feet, though compatibility is limited. Available in China for 499 yuan ($73), wider availability remains unconfirmed.
