In a blog post, Sony has announced the Android 4.4 update has begun for some of their devices. The Xperia Z1, Z1 compact, and Z Ultra will all get the Android 4.4 treatment. With the update come some changes for the device — some Android, some done by Sony.

Aside from the normal goodness Android 4.4 can bring, Sony is saying their media offerings — Walkman, Album and Movies, and cloud integration — will all be “converged” for a better experience. There will also be better PlayMemories integration, according to the blog post. That should make for a very ‘Sony’ experience across the board, but we’re not done yet!

Sony is also updating their native app portfolio. Though they’re not detailing just what’s going to change, Sony is saying just about all their apps will be updated to improve our experience with the devices. Messaging, MyXperia, Smart Connect, Small apps, TrackID, TrackID TV, Sony Select, and Smart Social Camera will all get updated to match the media app alterations.

Sony is also making UI tweaks aside from the native Android variety. They’re bringing in launch animations and wallpapers from the PlayStation, and tweaking the status bar and quick settings areas. They’re also creating downloadable ‘Xperia Themes’ packs for those who like to customize their devices.

If you don’t have a recent Xperia device, Sony hasn’t forgotten you. In Q2 of this year, Sony will be updating the Xperia Z, Z1, Tablet Z, and Xperia ZR. Later on, Sony will give the Xperia T2 Ultra, Xperia E1, and Xperia M2 the KitKat treatment, though they weren’t as forthcoming with a timeframe for those updates.
