The Galaxy S6 edge, announced at MWC in Barcelona, is closely related to the "standard" Galaxy S6 but the long edges of the phone are curved over the sides. It sports the same Exynos octa-core processor, 3GB of RAM and base 32GB of storage, but the 5.1-inch QHD display is simply curved on the sides.
Those curved edges aren't as feature-rich as the one found on the Galaxy Note Edge, but that's actually a good thing. There's no persistent edge screen software loaded — just a couple simple gestures that can be done from either edge to show contacts or missed calls and emails. The edges can also show a subtle desk clock at night or flash with bright colors when a call comes in and the phone is face-down on a table.
The Galaxy S6 edge also comes in its own exclusive color, a deep green that covers the front and back of the phone. It joins the standard black, white and gold colors that are also available on the Galaxy S6.
