Sony Xperia ZL Android 4.2.2

Sony has begun rolling out Android 4.2.2 firmware ( build number 10.3.1.A.0.244) for the Xperia Z and Xperia ZL. According to reports, the firmware is not listed on the PTCRB website but notifications should slowly begin appearing for owners. The best way to check for the firmware is by connecting your Xperia smartphone to your PC and running the PC Companion software from Sony. Depending on your internet connection as well, be sure to give ample download and install time as the firmware comes in at a hefty 758.5 MB size. Via Twitter, a member of the community has also pointed out that:
