Sony Xperia Z2 back cover leaks along with some specs30
The picture, if legitimate, reveals that Sony is moving away from the glass backs that it has been using on its high end models. Instead, it would appear that the Japanese OEM is using a metallic or carbon fiber material for the rear panel. The rumor also comes with a possible launch date, which is listed as next month. That would seem to indicate that we will see the Sony Xperia Z2 in February at MWC.
