Sony Xperia Tablet Z owners are in for some good news, as an update to Android 4.2.2 Jelly Bean is currently rolling out to their devices.

Android 4.2.2 Jelly Bean already hit the Sony Xperia ZR and now it's time for the Xperia Tablet Z to ditch its Android 4.1 Jelly Bean build for newer software. The update has firmware build 10.3.1.A.0.244, the same as the one hitting the Xperia Z, ZL and ZR devices.

According to the Xperia Blog, some users of the LTE model of the Sony Xperia Tablet Z (model number SGP321) have reported receiving the Android 4.2.2 Jelly Bean update already.

It seems that the update for the Wi-Fi versions of the tablet has not started rolling out yet. Judging by Sony's past schemes, however, those versions should get a taste of the newer Jelly Bean soon as well.

What's new?

The update from Android 4.1 to 4.2 Jelly Bean is not groundbreaking, but it does bring a few notable changes in terms of user interface (UI). The notification bar, for instance, is now moved on top of the interface, detached from the three capacitive buttons. This brings it in line with most Android devices.

The three capacitive buttons, meanwhile, are now relocated to the center instead of the left side of the bottom bar. This new layout is not only on par with what users expect from an Android tablet setup, but it also mirrors Google's efforts to unify smartphone and tablet interfaces with Android 4.2.2 Jelly Bean. The Small Apps button, which summons Sony's collection of productivity apps, has been relocated as well, if not removed altogether. This button was previously located in the top bar. The update also brings a pull-down quick settings feature, as found in Sony's Xperia smartphone series.

Little else is known at this point regarding the Android 4.2.2 Jelly Bean for the Sony Xperia Tablet Z, but more information should become available shortly. As previously mentioned, the update is currently rolling out only to the LTE version of the tablet, but the Wi-Fi models should get the same treatment shortly. Stay tuned for more updates as they emerge.
