During Mobile World Congress 2026, I was already blown away by Xiaomi and Leica's incredible Leitzphone that can take pro-level images, but Tecno's concept might take things even further.
By using various modules that snap onto a more standard phone body, this concept device can morph into various forms, including a huge zoom-lens-wielding cameraphone.
The phone's core is basically a superslim Android phone with a couple of connectors on the back. The connectors allow it to interface with various modules that the company had on display at its MWC booth in Barcelona. As a keen photographer, I was naturally struck by the giant zoom module.

Cinema camera-maker Red promised something similar with its Hydrogen One back in 2018, but the product never properly came to light.

The phone unit itself is very slim, but it only really needs a minimal camera setup and a small battery.
