Russia based YotaPhone launched the world's first hybrid E Ink / LCD mobile phone Europe only a few months ago, but the company already revealed a new 2nd-gen prototype phone. The main upgrade is the added touch capability on the 4.7" E Ink display, which enables it to be used for messaging, e-mails, browsing and more.

But I was also happy to hear that the 4.3" 720p LCD has been replaced by a larger AMOLED display. In fact, the new yotaPhone uses the same 5" Full-HD Super AMOLED display used in Samsung's Galaxy S4.
