The second generation of Yotaphone, smartphone with an LCD display and an e-paper Display at back, unfolds and landed this month in Russia.
The Yotaphone had marked the spirits by the presence of a second screen to the back of the unit and using e-paper technology with very low power consumption for display notifications and other practical information without having to activate the main screen.
The e-paper display is an interesting solution for mobile devices, but its limitations (monochrome display, inability to display videos, etc) make it difficult to make the main display of a smartphone.
By making a secondary screen at the back of Yotaphone the Yota Devices company has found a way to integrate it appropriately in a mobile product. After a first model that has toured the technology fairs, it is a Yotaphone 2 which is now announced.
It takes the concept of the two-screen smartphone with a 5-inch AMOLED display with full HD resolution (1920 x 1080 pixels) with a density of 446 ppi, and a back display of e-paper with resolution of 4.7-inch and 960 x 540 pixels and 16 gray, 236 ppi.
The Yotaphone 2 operates on a platform of Snapdragon 800 quad-core 2.2 GHz associated with 2GB of RAM and 32GB of storage memory. It also has an 8 megapixel camera with autofocus and LED flash on the back and a 2.1 megapixel camera at the front.
The smartphone is 9 mm thick and has wireless connectivity of WiFi, Bluetooth, NFC, GPS/Glonass Module and a micro USB 2.0 port. Note that the 2500 mAh battery can be recharged wirelessly.
The Yotaphone 2, which runs Android 4.4 KitKat, will be launched in Russia in the month of December 2014 for a fee of 33,000 rubles, or about $600/486 euros, before being offered elsewhere in Europe in early 2015.
