Xiaomi has unveiled an innovative modular phone concept at MWC, featuring an attachable Modular Optical System with a powerful 35mm f/1.4 lens and a 100MP Type 4/3 sensor—larger than any current smartphone sensor. Unlike past modular phone attempts, this system includes its own sensor, providing enhanced image quality. The module connects magnetically and utilizes Xiaomi’s 10Gbps LaserLink for near-instant data transfer, ensuring minimal lag.



Xiaomi has also integrated an autofocus motor within a compact 6G lens setup, keeping the module’s thickness close to that of the phone itself. The Modular Optical System does not require an external power source, drawing energy directly from the phone for seamless operation. Despite its potential, Xiaomi has no immediate plans to bring this concept to market but is open to customer feedback.
