Pictured: YotaPhone 2

Every once in a while, a smartphone comes to the market with a totally unique feature or form factor. There was the Galaxy S4 Zoomthe dual-screen Kyocera Echo, and Samsung's projector phone to name a few. The original YotaPhone, which included an e-ink display on the back side, certainly fits into this category.

The YotaPhone 2 was released in late 2014 for some regions, but the North American release was cancelled. Yota Devices has officially announced the next model, fittingly named the YotaPhone 3, at the China-Russia Expo in Harbin.

Details are rather scarce at the moment, but we do know there will be 64GB and 128GB models, priced at about $350 and $450 respectively. One source reports that the phone will ship in China in September, and pre-orders in Russia will start around that time.

Judging by Yota Devices' previous track record, a North American release will probably come later than that (if at all). Hopefully we'll learn more about the YotaPhone 3 soon.

Engadget claims that the YotaPhone 3 will have a Snapdragon 625 processor, which would make sense for the device's price point. The front screen will be a 1080p 5.5" display, with a 5.2" 720p e-ink display on the back. The phone will also have 4GB of RAM, dual SIM slots (one of thm can also be a microSD card slot), a 12MP back camera, a 13MP front camera, a 3,200mAh battery, and a USB Type-C port.
