Tecno has introduced a modular smartphone concept at MWC 2026, featuring a remarkably slim design at just 4.9mm thick. This measurement is notably less than that of a pencil and the iPhone Air, positioning it as one of the thinnest options in the market. The thickness increases with additional modules, but when the power bank module is attached, it aligns more closely with the dimensions of a typical modern smartphone.
The innovative modular design includes 10 interchangeable components, such as various camera lenses and a dedicated gaming controller. Tecno's new interconnection technology utilizes magnets alongside pin connectors to facilitate easy attachment and removal of these components. Wireless data transmission is supported through flexible connections like Wi-Fi, Bluetooth, and mmWave, adapting to the user’s environment.
Color options for the phone and its accessories include a silver-aluminum version and a grey variant. Despite the appealing design, it's important to note that this remains a concept, and its practical application in consumer products has yet to be confirmed. Tecno's ongoing commitment to innovation has previously resulted in affordable devices, but the modular smartphone market remains largely untested.
