Sony and T-Mobile US have rolled out the much awaited Android 4.3 for the Xperia Z. It is the firmware build 10.4.C.0.814 and contains many improvements over the earlier version.

The Sony Xperia Z was launched by Sony in the US last year only through T-Mobile. Early this week T-Mobile had announced certain updates to the Xperia Z. To be precise, it was the firmware build 10.4.C.0.808 update for the Xperia Z (C6606). However, no user seemed to get that update.

Later, the T-Mobile changelog showed the update as Android 4.3.0 and the firmware build as 10.4.C.0.814 and not 10.4.C.0.808 as declared earlier. The update file size seems quite heavy at 312 MB and the requirements for the update include Wi-Fi network, 315 MB available memory and 50% or higher battery life.

An upgrade from existing Android 4.2.2 Jelly Bean to Android 4.3 Jelly Bean is not much considering that other global Sony Xperia Z handsets have already received the Android 4.4.2 KitKat update. The US T-Mobile customers are lagging behind in this respect, but still it is an improvement over the existing version.

The new upgrade is available automatically Over-The-Air (OTA) during the period between June 2 and June 23. Once you receive the OTA notification, you can download the file and then click ok in the update center to install the update. If you haven’t got the notification, you can go to the home screen –> Applications –>Settings –> About Phone –>Software Update. The Xperia Z will check for update automatically. You can then connect to the Wi-Fi network and then download and install it. You can also download the update from a computer through the Sony PC Companion by connecting the Xperia Z to the computer through a USB cable.
