We miss YotaPhone’s e-ink backside
The YotaPhone 2was a second-generation Russian smartphone that was very cool! It had a 4.7-inch LCD on the front that let you access the Android OS and an e-ink display on the back to serve as backup. You could use that part of the screen for reading or even navigating maps if you were trying to save on battery. But according to our review of the device at the time, a “plethora of graphical issues and sluggish responsiveness” ultimately killed the smartphone’s chances of success.
