Another year, another MWC trade show, another flagship model added to Samsung's Galaxy line-up. Actually, make that two, with the new Galaxy S6 joined by a curved-screen doppelgänger, the S6 edge. Aside from the sloping sides of the S6 edge's display, both are cut from the same, premium cloth. Bound in aluminium, powered by identical octa-core chipsets, both hosting 5.1-inch Quad HD displays and 16-megapixel cameras, they are exactly what you expect new flagships to be. That is, the best smartphones Samsung has in its arsenal. And ahead of the global launch of the handsets on April 10th, they are now available to preorder from a variety of outlets in the UK.
