ZTE Axon M

Amidst all the grumbling about lack of innovation in the smartphone space, ZTE is trying something genuinely novel with the Axon M. Its 5.2-inch, 1080p display wouldn't be much to brag about if it didn't have a twin on the back. A hinge lets you place them side-by-side, giving you a 6.75-inch display. You can extend the home screen and apps to fill both screens, run two apps side-by-side, and even mirror the content, letting you set the phone up, tent-style, for two-person viewing. A Snapdragon processor, fingerprint sensor, and 20-megapixel camera round out the specs.
