The Sony Xperia Z Ultra Google Play edition is a device that falls under the phablet category, sporting a 6.4” display, and it has been certified for some Android 4.4.3 KitKat action. For those who want definite proof on the Bluetooth SIG, it is not there, but rather, one would stumble upon a reference to the “Togari GPE”.
Togari happens to be the code name for the Sony Xperia Z Ultra, while GPE stands for Google Play edition. As for the software version listed, it happens to be the KTU72.S1.3013, which is widely believed to represent Android 4.4.3 KitKat. Google Play edition smartphones rely on a stock Android OS, which makes it faster to update compared to unlocked and carrier models. After all, these updates are sent out straight from Google without having to go through any intermediary.
