A user on the Chinese Digi-Wo forums has posted an image of the back panel of the potential Xperia Z2. It seems that Sony will be using carbon fibre or some kind of metallic body instead of glass on the Xperia Z2. Or could this rumored phone be the old Xperia Z successor and not the Z1's?

The rumored specs is that this high end phone will have a 5.3-inch display and 23MP rear camera. So that would mean that the camera will be an upgrade from the 20.7MP used in the Sony Xperia Z1 and Z1 Compact. The phone will also come in 5 different colors.
