A report out of China, published on Friday, shows an image that purportedly reveals the back cover for the Sony Xperia Z2 , code named Sirius. The source of the photograph is said to be someone working in Sony's R&D department. The picture was accompanied by a short list of specs. According to the Sony insider, the phone will feature a 5.3 inch screen, be equipped with a 23MP rear-facing camera, and is expected to be offered in 5 colors.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.Thanks, Anonymous Tipster!source: Digi-wo (translated) via gforgames
