Yota’s improved two-screen phone
Yota Devices will release an improved version of its front-and-rear screen phone by year’s end. The Yotaphone idea offers a conventional front screen (5-inch AMOLED) but, on the back, a second e-paper screen, which can remain on all the time without draining the battery. The new model will let users respond to notifications, SMS messages and email appearing on the e-paper screen without having to flip back and wake up the front screen. The 4.7-inch e-paper screen will have higher resolution, finer pixel density and a light. The vendor claims a battery life of around 50 hours when using the e-paper screen. The display is suitable for text-based applications but is monochrome only.
