Xperia Tablet Z WiFi owners, the time has come for you to make the jump to Android 4.2.2. The latest firmware update, version 10.3.1.C.0.136, updates the six-month tablet to the next version of Jelly Bean and brings with it a slew of features worth salivating over, such as support for 64GB SD cards, and some that may be more subjective, such as the transition from a tablet UI to a phone UI. This means that the soft buttons (back, home, and recent) are now centered at the bottom of the screen, and the notification bar has been shifted to the top. Like the update that previously rolled out to the LTE version of the tablet, some elements of the UI still differ from that found on Nexus devices.
