When I checked out the WiFi-only version of the Xperia Tablet Z I was surprised by how solid it was. One of my main gripes was the old software and the UI that came with it. Well, the first variant of the Tablet Z is now getting an update to Android Jelly Bean 4.2.2, and it changes the interface to a hybrid of the old UI and new UI used on the Nexus 7 and Nexus 10.
Rather than stuff all the buttons in the corners, the navigation buttons are more centralized now, and the notifications are up at the top like phones and more recent tablets. The app drawer and Google search are still in the upper corners for some reason. The standard 4.2 features are included as well. You can check our review for the previous look.
This update (firmware build number 10.3.1.A.0.244) is currently only working with the LTE version of this tablet. The two WiFi variants are assumed to be next on the update docket, but no word yet.
