I bought the phone as a gift. The reviews were already good. The successor Z1 was too expensive, but that he actually "only" a better display (but same resolution) and still has a higher-resolution camera (where am I with the megabyte images? The can email more so none). The Z has been super much computing power, a great display (also legible outdoors) and a memory expansion slot in case. Android 4.1 was given and on the equipment delivered. When I played the old people contacts by an ancient Nokia to Z, announced the Sony PC Companion that he still had also updates for the Z. I then let it install and came out that he had updated the Android 4.3 on. So you end up at the same level as the Z1.
So Super device. Until now only the best experiences. The Sony PC Companion (free of d. Sony website loaded) it updated to Android 4.3.
