Xiaomi has introduced a modular smartphone concept designed to address the issue of protruding camera bumps at the Mobile World Congress 2025.
The design features a detachable lens system that enhances imaging capabilities while maintaining a slim and streamlined device profile.
The system includes a 35-mm detachable lens module that magnetically connects to a modified Xiaomi 15 smartphone. This allows users to attach the lens when needed for improved photography while keeping the phone compact when the module is removed.
The modular system features a 100-megapixel Light Fusion X Type 4/3 sensor, which is larger than standard smartphone sensors, aiming to improve image quality and low-light performance.
It also incorporates a variable aperture mechanism, giving users more control over depth of field and lighting conditions.
The attachment mechanism relies on a magnetic connection with pogo pins for power transmission and Xiaomi’s LaserLink technology for high-speed data transfer, supporting speeds up to 10 Gbps.
Once connected, the lens integrates with the phone’s camera app, providing autofocus and a physical focus ring for manual adjustments.
Xiaomi has presented the modular optical system as a prototype with no confirmed commercial release. The company has suggested that the system could be extended beyond detachable camera lenses to support other modular accessories in the future.
The approach provides an alternative to conventional smartphone camera designs, which have relied on larger sensors and multiple lenses, often leading to prominent camera bumps.
Modular camera systems have been explored in the past, but adoption has been limited due to concerns over durability, ease of use, and consumer interest. Xiaomi’s design aims to address these challenges with advanced connectivity and a seamless user experience.
While the concept represents an effort to balance smartphone design and camera performance, its viability in the market remains uncertain.
As a prototype, it highlights the potential for modular smartphone technology but will require further development before determining whether it can offer a practical solution for consumers.
