After Sony rolled out the Android 4.2.2 update for the Xperia Z about a month ago, now a new update for the update has appeared, carrying the firmware number 10.3.1.A.0.244.

The update seems to be simultaneously released also for the Xperia ZL and ZR handsets, and users worldwide are reporting it is hitting their handsets.
