Oppo Bubble is the magnetic selfie screen Apple still won't build
Oppo has launched a small magnetic display called Bubble that clips to the back of a smartphone and lets you take selfies with the rear camera — a trick Xiaomi baked into the 17 Pro at significant cost, now available as a standalone add-on for around $73. The disc is 7mm thick, weighs 27.5 grams, and packs a 550mAh battery. For anyone who's ever wished their front camera was as good as the main one, the concept is straightforward: Bubble shows a live preview on the back of the phone while the subject looks into the rear lens.
The accessory argument
The circular touchscreen is AMOLED and attaches via built-in magnets. Beyond selfies, it doubles as a secondary display for wallpapers, photos, and short videos — and supports a wireless remote shutter with up to 10 meters of range, useful for framing group shots without handing your phone to a stranger. Oppo also sells a case that converts the Bubble into a keychain fob when it's not in use.

The accessory model has a real economic logic behind it. Xiaomi embeds a secondary rear screen into every unit of the 17 Pro regardless of whether buyers want it, driving up the base price. Oppo's approach lets the hardware stay standard while curious users opt in separately, as Digital Trends notes in their hands-on coverage.
Compatibility caveats
Oppo officially lists compatibility with the Reno 14, Reno 15, Reno 16, Find X8, Find X9, Find X9 Pro, and Find X9 Ultra. The Bubble will physically attach to any Qi2 phone — including the iPhone 17 — but Oppo says it works best on its own devices. That qualifier matters: the wireless live preview relies on a proprietary Miracast-style link, and phones outside the supported list won't get the full feature set. Per Gadget Hacks, Pixel and Samsung Galaxy owners face real ecosystem gaps that attachment alone can't solve.

Oppo launched Bubble in China on May 25, 2026 at CNY 499 (roughly $73). No US or UK retail partners have been announced. Oppo doesn't sell through US carriers, so any stateside availability would come via grey-market imports or a direct online push — neither of which has been confirmed. For now, this one is China-first and worth watching if Oppo expands its Western rollout later this year.
