We haven’t noticed any tangible differentiation to how these cases operate versus the Style Cover Window cases for the Xperia Z3 series. The case allows you to access five customisable widgets through a smart window. The cases are water (IPX5/8) and scratch (3H) resistant and uses NFC to easily connect to your handset. The front cover also includes a magnet to switch between modes. Expect the Style Cover Window cases to be available in time for the Xperia Z5 series launch across the same colours as the handsets themselves.
