SONY announced Android 4.3 Jelly Bean Update for Sony Xperia Z1 and Xperia Z Ultra

SONY:

We’ve been working to blend our Sony Xperia software with Google’s Jelly Bean release to create some cool user experiences (if we say so ourselves) – in addition to a few performance tweaks here & there, some of the functionality you can look forward to includes:
 

Google’s Android 4.3; Jelly Bean as standard – bringing Project Butter performance & UI optimisation and a smoother graphical experience
 

Launched with Xperia Z1, we’re now bringing Sony’s Smart Social Camera to Xperia Z Ultra – our signature camera experience, that lets you download, access and enjoy “Xperia camera apps” directly from within the viewfinder
 

We’re also uplifting Sony’s entire native app portfolio to the latest versions – bringing tweaked / improved / current experiences for (to name but a few): Messaging, MyXperia, Smart Connect, Small apps, TrackID, Sony Select and…
 

Sony’s Media apps: WALKMAN, Album and Movies, with Sony Entertainment Network cloud service integration* - a more converged and full Sony entertainment experience – Sony Entertainment Network & PlayMemories integration with a more intuitive UI, offering seamless access to both local and cloud content
 

The launch of our unique custom interface experience: “Xperia Themes”, with downloadable UI packs from Sony Select – more on this soon…
 

The latest Android security enhancements, matched with Sony’s mobile enterprise solution: Xperia in Business

Our Android 4.3; Jelly Bean rollout for the remaining Sony Xperia products is right around the corner – we’ll be back with more details; bespoke feature sets and timings as things progress
