With its QHD screen and metal design, this is the smartphone to beat in 2015. The Galaxy S6, is - of course - the sequel to last year's Galaxy S5, which if reports are to be believed, didn't go down well with smartphone buyers, with sales coming in 40 percent lower than Samsung had hoped.

With that in mind, Samsung has taken a fresh approach, and has redesigned the Galaxy S6 from the ground up, no doubt in a bid to compete with the likes of the iPhone 6 and HTC One M9.
