Oppo’s Bubble selfie screen highlights a missing wireless standard

This tiny puck features a 550mAh battery and connects wirelessly to your smartphone, providing a live viewfinder for high-quality rear-camera shots. At just 7mm thick, it manages to bypass the need for cumbersome cables, offering a range of up to 33 feet for remote shooting. Oppo packages the device with a silicon bumper and a star-shaped lanyard, signaling a focus on versatile, off-hand use cases rather than just fixed mounting.

Despite the impressive form factor, the hardware lacks the seamless integration offered by the Qi2 standard. Users are relegated to basic camera controls, missing out on tap-to-focus functionality and full-frame aspect ratio support. While the circular touchscreen provides a functional interface for zoom toggles and shutter release, the reliance on proprietary magnetic attachments feels like a relic of a fragmented ecosystem that could be easily solved by adopting a unified magnetic power and data standard.
