Sony is a bit late to the party, but the Japanese manufacturer is finally joining the ranks of Samsung and HTC and has begun upgrading two its flagship devices, the Xperia Z1 and the 6.4-inch Xperia Z Ultra, to Android 4.3 Jelly Bean. The update will begin rolling out today and reach all devices over the course of this month and the next, and bring all the goodies of Android 4.3, such as faster performance, Bluetooth LE (low-energy) and OpenGL 3.0 support, improved accessibility, among others.
Sony has naturally added numerous enhancements of its own as part of the upgrade. These include improved and updated versions of apps like Messaging, MyXperia, TrackID, Small Apps, WALKMAN etc., the Smart Social Camera app for the Xperia Z Ultra, and a unique custom theme interface called “Xperia Themes” with the option to download custom UI packs – Sony says details on this feature are forthcoming, though it basically sounds like an improved version of the theme functionality that is already available on all Xperia handsets.
Other Sony devices, such as the Xperia SP, Xperia T, and Xperia Z, should be receiving Android 4.3 this month as well, and more details on the update can be found at the source link.
