Samsung has already confirmed that it will have an Unpacked event on the 21st of February, which we take to mean an unveiling of the Galaxy S7, among other things. So there's really nothing else to do but wait. Or while the time with even more leaks and rumors. The Galaxy S7, to be honest, has all but been leaked to death, but finer details are still cropping up here and there. Take for example this latest schematic showing off the smartphone's non-flat rear, both in terms of design and in terms of the camera hump.
