Xperia Z1

Performance tweaks and camera improvements for Z Ultra among changes in latest Sony firmware

Sony had previously promised that the Android 4.3 rollout for certain Xperia phones would begin this month, and now the first two devices on the list are being updated. Android 4.3 for the Sony Xperia Z1 and Xperia Z Ultra has started rolling out today, bringing an update from 4.2.2 and some Sony software improvements.

Among the changes are enhanced performance and updates to Sony's suite of built-in apps, such as Messaging, My Xperia, Smart Connect, Small apps, Track ID, Sony Select and the media apps, including Walkman, Album and Movies. As of this release the Xperia Z Ultra also gets access to Sony's "Smart Social Camera" feature from the Z1, which lets the rear camera use Sony's downloadable camera apps. The new firmware also supports downloadable themes through the Xperia Themes system, a feature Sony says it'll expand upon in the future.

Update: Xperiablog also reports that the Z1 camera issues for bootloader-unlocked phones has also been fixed.

The update should be available now for some Z1 and Z Ultra devices, though Sony points out that as with all updates it'll take time to roll out to all regions and carriers. (We're not yet seeing anything on our unlocked UK Z1, for what it's worth.) If you're updating your Xperia Z1 or Z Ultra today, hit the comments and let us know how you're getting on.
