Sony has announced that a previously promised maintenance update for the Xperia S, Xperia SL, and Xperia Acro S is hitting the internet tubes now. These devices received an Android 4.1 update a while back, but now the OEM is tying up some loose ends with a new Jelly Bean build. It should reach all users soon.

Sony was good enough to include a full changelog, so here's what you can expect:

  • Camera
    • addressed an abnormality in the white balance
    • improved the “Quick Launch” button functionality
    • smoothed out (1080p) video recording, minimizing lag
  • Apps and services
    • streamlined Exchange Active Sync, particularly when running an encrypted set-up
    • boosted connection stability for 2G network data
    • ensured preferences on 3rd party apps remain after reboot – not a common problem, but we understand it can be a frustrating one!
  • Battery
    • economised power consumption, and heat dispersion for longer life
    • corrected juice level notifications, especially when running low
  • Hardware and UI
    • introduced a home key long-press to launch Google Now, and a double-press to launch Recent Apps
    • made sure the volume “up” button is fully responsive

You probably wouldn't get this kind of attention with an older device connected to a carrier, so good on Sony. Sure, it's not 4.3... or 4.2 for that matter. It's still nice to see these devices haven't been left in the dust, though.
