In their current states, the Sony Xperia Z (C6603) and the Xperia ZL (C6503) are great devices. However, a sad truth is that virtually all OEM-skinned devices fall behind their Nexus and Google Play edition comrades when it comes to Android version updates. And while an official KitKat update probably won’t make its way to the two devices before 2014 begins, a leaked version of 4.3 has already made its way onto the forums.
The leak for the two devices comes come courtesy of XDA Recognized Developer Androxyde. Both builds are version number 10.4.B.0.569, and are labeled as being for “Commercial&Journalists.”
So far, user response has been quite positive for both builds, with many users mentioning significantly increased performance. And while these updates are currently unofficial leaks, it is possible for them to become suitable for mass consumption, as we’ve seen in other devices.
