Sony Xperia Z2

Sony is rolling out an update to its latest Xperia Z2 phone and Xperia Z2 Tablet, bringing the build number to 17.1.1.A.0.402. Currently, no changelog is provided from Sony so we don't know what changes have been made, though reports are suggesting that a few areas are seeing some noticeable improvements. This is the first update for the devices since they launched and the version number has jumped a bit, so we are anticipating that there should be some big changes inside.

The update is starting to roll out in select regions at this time, hitting the unlocked versions of the Z2 and Z2 Tablet in Germany, Singapore, and Europe, but not the UK region just yet.

Sony Xperia Z2 Theme Chooser

In our testing of the update on our Xperia Z2, we noticed that touchscreen sensitivity has been improved. There is also a new interface for applying themes now as well. Additionally, scrolling lag in the fancy PlayStation-style live wallpaper also seems to have been eliminated, making for a smoother experience.

The update is being pushed out now to both the HSPA+ and LTE variants of the Xperia Z2 phone and also on the LTE and WiFi editions of the Xperia Z2 tablet. There should be other performance improvements as well under the hood that will take us more testing to uncover.

If you're a Z2 or Z2 tablet owner and find any changes or improvements, let us know either here in the comments or in the forums.
