Earlier this week, we did talk about how the Sony Xperia ZL would be on the receiving end of an Android 4.2.2 Jelly Bean update, and considering how close the Xperia Z and Xperia ZL are in terms of hardware specifications, it is not surprising to hear of the Sony Xperia Z, too, being on the receiving end of the Android 4.2.2 Jelly Bean update after months of waiting, sandwiching some delays in between to boot.
This is definitely good news for those who have waited for their fair share of months, especially after Sony Mobile did promise that the Android 4.2.2 Jelly Bean update would arrive shortly after launch, only to renege on that promise until now. Apparently, some Xperia Z owners have already reported to have received the Android 4.2.2 Jelly Bean update on their respective smartphones, but chances are this will be a staggered rollout, so it might take some time before your Xperia Z will be able to roll with the latest version of Jelly Bean.
A quick look around the Internet points to the Android 4.2.2 Jelly Bean update targeting non-branded devices that have been sold unlocked in Taiwan (otherwise known by its model number, C6602), as well as in Spain and Ukraine for the LTE version (model number C6603), in addition to select numbers of carrier-specific variations in Austria, the Czech Republic, and the Netherlands. Expect the latest firmware build to carry the version number 10.3.A.0.423, and the rest of the Xperia Z populace should be able to embrace Android 4.2.2 Jelly Bean fully in the coming weeks.
