There are hundreds if not thousands of smartphones available today yet since the launch of the iPhone seven years ago little has really changed.

Sure smartphones have gotten bigger, lighter and faster while millions of apps have been created for them, but in terms of how we use the our phones, we have seen very little innovation.

That could be about to change however with the launch of the second generation YotaPhone, a device with not one but two screens.

Vlad Martynov, the man behind the revolutionary device, believes he can take on the likes of Apple and Samsung and that dual-screened smartphones could soon become the norm.
