At the MWC 2026 event, Tecno introduced an innovative modular smartphone prototype that stands out for its slim profile. Unlike typical modular designs that tend to be cumbersome from the start and even more so after adding extras, this model's core unit measures only 4.9 millimeters in thickness—slimmer than a pencil or the iPhone Air.
Adding modules does increase the device's dimensions, but equipping it with the power bank accessory results in a profile similar to that of conventional current smartphones. A notable aspect is the attachment method for these modular elements. Tecno has engineered a fresh connection system combining magnetic forces and pin-based links, facilitating straightforward installation and detachment of parts.
According to the manufacturer, the device is intended to evolve alongside its owner by incorporating additional hardware. Supporting this, Tecno created a lineup of 10 distinct modules, including multiple camera attachments and what appears to be a specialized gaming accessory.
While magnets secure the components in place, the pin connectors manage electricity transfer. Communication of data between the main unit and modules occurs over wireless channels, with options to alternate between Wi-Fi, Bluetooth, and mmWave protocols based on the user's surroundings.
The smartphone and its accompanying modules come in two variants: a silver-aluminum finish and an attractive gray option. Since this remains a prototype, such aesthetic choices hold little relevance for potential buyers at present. That said, the magnetic fastening approach shows promise for integration into future commercial offerings.
Tecno has long pursued unconventional paths in mobile innovation, producing a budget-friendly folding device, a variant featuring an extendable lens for portrait shots, and a foldable model with a unique round screen on the back.
The smartphone sector has yet to fully adopt modular architectures, despite intriguing prototypes over the years. Google's Project Ara dates back over ten years, and numerous other ideas have stayed confined to the drawing board without reaching markets.
A few modular devices have made it to consumers, though none matched the scope of Tecno's vision. In 2016, LG released the partially modular G5, which saw limited commercial success. Motorola has also brought out semi-modular models, but they failed to achieve widespread popularity.
