Tecno unveils modular phones with ultra-thin magnetic design

During the Mobile World Congress, Tecno showcased a 4.9 mm thin modular smartphone with no built-in charging port. The unnamed concept allows accessories to attach to the back of an ultra-slim Android handset via magnets and low-profile pogo-pin connectors. Among the modules on display were multiple camera attachments, a wireless microphone, a clip-on speaker and a fold-out antenna module.
