7. Nokia Lumia Yega

Design-wise, Lumia Yega has a pretty large screen with a slim body. Besides, the device looks like something all-alloy. Nevertheless, the key feature here is the rotating one. As you can see, once you want to browse on a big screen, you can rotate the a half of the handset to show a full edge-to-edge display. On the contrary, if you need to type on a physical keyboard, just twist it and use half of the size of the display and a QWERTY keyboard on the other part. Spec-wise, Yega will own Windows 10 OS, and hopefully some strong specifications like 4GB RAM and a 4,000mAh batt will be on board as well.
