At the China International Exhibition, which was held on September 24-28, 2013, ZTE company, known not only in China, but also in the world, presented its version of a modular smartphone called ECO-MOBIUS, which the user can freely assemble or upgrade.

Photos from the exhibition:

This year, the concept phone has received an authoritative award in the field of design
Red Dot Award .
The smartphone consists of 4 modules: processor, display, battery and camera. The main module, which consists of a screen, is inserted into the CPU, GPU, RAM, camera, memory card and battery.

All components are mounted in grooves using a magnet. The whole thing is covered with a lid.

The name of the smartphone emphasizes the idea of reducing the burden on the environment from waste and pollution. Apparently this should be achieved by replacing only individual components (which are out of service or require modernization), and not the entire apparatus.

Clearly, this is only a concept. But who knows, maybe we are creating not only a new type of electronic device, but also a whole consumer electronics market ...
