YotaPhone. Always-on dual screen, thicker than most, but not by much
The YotaPhone is a smartphone from Yota Devices Ltd., a Russian company that also manufactures a portable LTE router called Ruby.
YotaPhone is an Android smartphone, running Android 4.2.2 Jelly Bean. But it’s different from other smartphones (Android and otherwise) in that it comes with a dual screen (it’s a double-display smartphone). On the front is a 4.3-inch, HD LCD display and on the back is an e-ink display that’s also 4.3 inches.
