Sony is pushing over the air updates to its Z1 and Z Ultra. These are quite important updates so you may want to request the software update from within the system settings l.
With the Z1 the upgrade brings several camera tweaks and new camera algorithms for better all round performance. There have also been some changes to the Sony smart camera platform, which now enables built-in apps to run more fluidly.
The Xperia Z Ultra update brings optimized touchscreen sensitivity for fingers and styluses, therefore, effectively broadening the range of input methods, empowering the device to compete with the likes of Samsung’s flagship Galaxy Note III.
In addition, both the Z1 and Z Ultra will receive battery life enhancements, display calibration tweaks and significantly faster e-mail synchronisation over Microsoft Exchange.
Sounds like very good updates.
