What you can see below is the first screenshot of the Android 4.2.2 Jelly Bean update for the Sony Xperia Z (C6603). The Image was Spotted on Xperia Blog. According to Xperia Blog the Images were given to them as a tipster who named his name as Anonymous. It shows that the Android 4.2.2 Jelly Bean update will have firmware version 11.1.A.1.450. However, Xperia Blog says that, the firmware version number to be in the form of 11.1.A.X.XXX by the time it is released.
It uses a new 3.6 kernel, compared to 3.4 kernel of the Old Android 4.1.2 firmware. Best of all, we are told that the official release for this Android 4.2.2 Jelly Bean firmware will take place at the end of March in Europe. Obviously none of this is official information so take it with a pinch of salt, but if Sony does manage to upgrade the Xperia Z a month after release many customers will be very happy indeed.
