The second generation of the dual-screen YotaPhone will be landing later this year.
The Android handset, announced at the MWC trade show in Barcelona on Monday, has two screens: a full HD AMOLED front-facing display, and a rear-facing e-ink equivalent.
The e-ink screen shows notifications such as missed calls, emails, and social media updates. It's also a touchscreen, meaning YotaPhone users can respond to the notifications using only the second screen.
According to its manufacturer, Yota Devices, using the e-ink screen ups the device's battery life to 50 hours of reading time.
At 4.7 inches, the e-ink screen is slightly smaller than its five-inch liquid crystal counterpart. The e-ink screen's resolution is 960x540-pixel, compared to the AMOLED screen's 1920x1080.
There's also NFC, wireless charging, and a Qualcomm quad-core Snapdragon chip onboard.
White and black versions of the device, powered by KitKat, will go on sale in EMEA and Russia in the fourth quarter of this year.
A US and Asia launch will follow a quarter or so later, Yota Devices said. It's expected to retail in the region of €449 unlocked, according to CNET.
The first generation of the YotaPhone was announced at last year's MWC, and went on sale in December. Those who bought the first-gen device will get a discount on its successor, Yota Devices said.
Yota Devices also announced an SDK for the device yesterday, to encourage developers to build dual-screen apps.
