The device, which features both a typical smartphone touchscreen on its front and an e-ink screen on its back, debuted at the MWC trade show in Barcelona last year.
It was launched in December in a number of other markets including Germany, France, Austria and Spain, as well as Russia, the home of the phone's maker Yota.
The YotaPhone's touchscreen is a 4-3-inch 720x1280 LCD display, while the rear screen is a 360x640 e-ink screen of the type more commonly seen on e-readers. The second screen is not a touchscreen, but does have a touch-sensitive area underneath for navigation and controls.
The idea behind the second screen is that it's a way of showing notifications – such as message alerts – without draining the battery as much as displaying them on the main screen would, according to Yota.
The handset also pack a 13-megapixel front-facing camera and a one-megapixel front-facing equivalent, a 1,800mAH battery, 2GB of RAM and 32GB of onboard storage. It's powered by Android Jelly Bean 4.2.2.
The device will sell in the UK for £419, around the same cost as it's been retailing for in mainland Europe: €499.
The YotaPhone will go on sale "later this month" in more European countries, according to its maker, including Portugal, Italy, Switzerland and Scandinavia.
A second generation of YotaPhone is already in the works. Previewed at this year's MWC, the handset has a slightly bigger display at 4.7 inches, with a full-touch e-ink second screen. It's set to go on sale in December this year.
