The original version of the YotaPhone was quite a novelty, a dual-screen smartphone is always worth talking about. The only downside is that it didn't quite cut it, with that rear screen not being particularly interactive. Not so the YotaPhone 2.The YotaPhone 2 is an early step up for a phone only launched back in December. Early criticisms have obviously been taken on board, with the second version replacing the original notification-only rear panel. It's still an E-Ink panel, only this time, it is touch sensitive, so you can interact with the calls, texts, tweets and emails on the 4.7-inch screen.The phone also has a 5-inch, 1080p AMOLED screen on the front, as well as including an enhanced 2.3GHz Snapdragon 800 processor, with NFC and wireless charging also new additions. Still present is an 8-megapixel rear camera, along with 32GB of internal storage. Android 4.4 KitKat is the operating system, although a number of apps are unable to run on that rear screen just now. Fine on the front though.It's still a prototype, but it does look like an impressive piece of kit so far. It'll be interesting to get hands-on with the finished product. Who wouldn't like the idea of playing with two screens? But it'll be some time before that though, as the new model isn't going to be in Europe until late 2014 sadly.
