To compete with Motorola's Project ARA, Chinese company ZTE has announced their very own modular Smartphone concept. Eco-Mobius is on display at ZTE's booth in Las Vegas, and the concept phone looks very similar to what Motorola had shown us months ago. Modules such as CPU core, RAM, camera, battery, etc. are all fixed to one another using magnets, allowing for easy replacement. Upgrading components of a phone rather than changing the entire phone can turn out to be both cheaper and more environmentally friendly...
