Pretty good news to all Sony Xperia Z users that new Android 4.2.2 update has been leaked. If you’re really excited you can install the update on your phone now and it is only available for those with unlocked bootloaders.
It is an official update released by an XDA Developer and the leaked firmware corresponds with software build number 10.3.A.0.407. The UI is almost same though there are some Android 4.2 additions such as customizable lock screen as well as access to quick settings on the drop-down notifications.
