I have very beautiful Mobile. The Xperia M4 Aqua Dual is all plastic and glass, with a completely flat back and curved sides. The white and coral pink versions look good but the black version, which we received for review, is especially striking because of how stealthy it looks. Its sheer body is broken only by silver brand logos, a ring around the rear camera lens, and the power button on the side. With the screen off, its like shiny black slab.
The sides are curved and have a non-slip matte finish, but the flat back doesnt lend itself to a very comfortable grip. Theres a scratchy seam all the way around, where the edges curve inwards to meet the rear. The unit is completely sealed so all ports and slots are externally accessible. The MicroSD slot is on the upper left while the two Nano-SIM slots are on the upper right, all behind rubber-lined flaps.
