If you hate the big camera bump of today’s smartphones, you’ll love the detachable lens of Xiaomi’s Modular Optical System.

Xiaomi is showing off its Modular Optical System concept at MWC 2025, but the most interesting part of it is its LaserLink technology.

Xiaomi’s not the only company toying with this idea. This week rival Chinese phone maker Realme introduced a concept phone with a 1 inch image sensor that isn’t designed to work with a built-in lens. Instead you can attach any camera lens that uses the Leica M Mount system to the back of the phone.
