It's not KitKat, but at least the Sony Xperia M is getting a little update love from the mothership today. Android 4.3 is rolling out now, but as usual, the exact timing varies by country and carrier. Heading into the update menu and refreshing will pull down the file if your device is eligible.
Android 4.3 (build 15.4.A.0.23) for the Xperia M includes the following goodies.
- Google Android 4.3 (Jellybean), bringing smooth UI and graphics enhancements
- New version of Battery STAMINA Mode for longer battery life
- Updated camera interface bringing Burst Mode, Superior Auto & More
- Updated applications from Sony featuring Walkman, Album, Movies & More
- Latest security enhancements from Android 4.3
Most versions of the device should already be on Android 4.2.2 at this point, so there aren't many big changes on the OS side.
