The YotaPhone 2, a smartphone with a second electronic paper display on its rear side, is set to go on sale in the UK, December 3rd. It's the sequel to the first YotaPhone, and looks very similar to a prototype from Yota Devices that we saw at MWC earlier this year. The secondary display consumes far less power in comparison to traditional screens, and can be used as a battery-efficient way of accessing social notifications, sports scores, weather information, and other data.

The YotaPhone 2 includes a conventional 5-inch 1080p AMOLED screen along with a 4.7-inch always-on electronic paper display; it's unclear whether the second screen is using E Ink or some other technology. As for other specs, there's a Snapdragon 800 processor, 2GB of RAM, 32GB of storage, a 2500mAh battery, and an 8-megapixel camera. The YotaPhone 2 costs £555 (about $870) and is available for purchase at a pop-up store in London or via the company's website. Outside of the UK, the phone will be available direct from YotaPhone in 20 countries across Europe, the CIS, and the Middle East for a cost of €700. US availability is expected for 2015.
