‘Yota’ Smartphone uses second e-Paper display on back.

 The 4.3 inch Android phone features a grayscale e-Paper display on the back, able to show any information or image from the main front screen. By swiping down on the main screen with two fingers, a screen shot is transferred to the back display. This could allow a map to be stored easily to be re-checked later, for example.

Apps can also be developed to send information to the screen, allowing uses such as an eReader, an always-present alert system or a post-it note. A small touch sensitive area next to the e-Paper screen allows users to flip between pages of a book or interact with apps which use the second screen.

e-Paper displays only use power when they change, so it shouldn’t be a huge battery drain. The phone runs Android 4.1, has a dual-core Snapdragon CPU, 2GB of RAM and 16 or 32GB of internal storage. The company is looking for carrier partners in the US, but may still launch under it’s own brand there in the future.
