Samsung’s Galaxy S Duos 2 GT-S7582 looks like a typical member of the Samsung Galaxy S4 models and stands out with its stylish appearance that would not necessarily be expected from a 159 Euros ( ~$221) smartphone. Rounded corners and edges, a glass panel for the 4-inch screen fitted seamlessly into the plastic chassis, and illuminated Android buttons. The fingers find a secure grip on the lightly structured back of the light, 118-gram device. The slim, 10.6-millimeters chassis is available in black and white. It is very rigid and defies all careful attempts to dent or warp it in the test. Only the casing’s removable lid on the back, that conceals the removable battery and both slots for full-sized SIM cards, can be dented marginally.
