Sony Mobile had stated that the Xperia ZR (C550X) Android 4.2.2 firmware update will roll out in early August, but it appears that some users already have it. Firmware version 10.3.1.A.0.244 is the same build that hit Xperia Z and Xperia ZL handsets yesterday. The update is out in Norway and is likely to hit other regions soon. If you have the Xperia ZR and have the Android 4.2.2 update let us know which region your handset is from and what changes you’ve noticed.
Thanks LilliApril!
