For many people, buying a phone is equivalent to buying a personal camera. But Chinese phone-maker RealMe is blurring that line with a concept device that lets you change the lens on the phone, much like on a high-end mirrorless camera.

MOS was on display here at MWC 2025, and the idea behind this concept device is that you can attach compact camera lenses onto the back of your phone. Forget the iPhone's MagSafe; this takes things to the next level.

Realme and Xiaomi showed off concept devices at Mobile World Congress that involve attaching a lens to your phone to get sharper shots.
