Obviously the two sides have different uses and offer a more versatile offering for users. As would be expected the front is just like any other smartphone with a typical LCD to browse, text, watch videos, and usual tasks.
The other rear display, with e Ink technology aims to offer a slighlty different experience. As an electronic paper display, it is mainly utilised by pushing content to it from the front LCD. The main idea is that it’s not so much as a functional screen like the front LCD, but more for display and information hoarding. For example you can utilise the e-ink display to display a map of where you are, a count down clock, a boarding pass for a plane and other uses currently being devised.
The short term aim of the manufacturer is to release an API so other developers can also develop applications that take advantage of having two displays on the single device.
The phone will be running Android 4.1 Jelly Bean, and is planned to be as clean or ‘vanilla’ as possible . At time of writing the phone is also planning to use the Qualcomm Snapdragon MSM 8960 platform, and Corning’s 3D Gorilla Glass. It can also run on any LTE network globally using a multi-band LTE chip.
YotaPhone is expected to go one sale during the second half of 2013.
