Let's forget about KitKat for a moment. A large number of Android devices out there still need an update to the latest version of Jelly Bean, and while many of them will never receive such an OTA, four of Sony's handsets are receiving one this week. The company is rolling out an update to the Xperia T, TX, SP, and V.

In addition to Android 4.3, the OTA brings updated Sony pre-installed apps, more integration between the company's media apps, and the launch of the new "Xperia Themes" custom interface. These are joined with the security enhancements that typically come with newer versions of software.

  • Google’s Android 4.3; Jelly Bean as standard – bringing Project Butter performance & UI response optimisation and a smoother graphical experience
  • 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, 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
  • Battery STAMINA Mode – updated version of Sony’s power management app, now with refreshed interface and more smart options for prolonging battery life

Just because Sony is pushing out the update this week, that doesn't necessarily mean you will receive it right away. Timing varies according to device, region, and carrier, so some of you may need to be patient just a while longer.
