The update will add ‘Project Butter’ to the phone as well as UI tweaks which adds a ‘smoother graphical experience’.
Amongst a host of App updates to apps like Messaging, MyXperia, Smart Connect, Small apps, TrackID and Sony Select, Sony has also taken the opportunity to give the Z Ultra the same Smart Social Camera experience that launched on the Z1.
There’s updates to Sony’s media side of things with WALKMAN, Album and Movies receiving an overhaul to improve access to local and cloud media content.
Another bonus, according to the Sony-centric XperiaBlog, this update is also apparently fixing a bug which affected Xperia Z1 owners who had their camera stop working after unlocking the bootloader on their phone.
The rollout is of course going to take time to hit devices based on carrier testing, however one Ausdroid reader who purchased his Xperia Z Ultra on contract through Optus is advising that he has now received the update :
The Android 4.3 update is listed on the software update pages for both carriers who chose to carry the Xperia Z1, with Telstra advising an update is due to hit customers on the 6th of January, with Optus advising a similar date with their page advising an expected date of ‘Early to Mid Jan’.
