Here at CES, ZTE is showing off its own modular phone concept, named the Eco-Mobius. However, thats all the Eco-Mobius is for now — its just an impressive design. As a design concept, this is merely a visual look at what ZTE imagines a modular phone could look like in the future. A representative at ZTEs booth was clear that the company was not developing the phone, though engineers may be working towards addressing the numerous difficulties that must be overcome before a phone like this ever becomes a reality.
