Sony is on a roll. Today is 1 February 2017 and Sony has today seeded a new firmware update for the Xperia XZ and X Performance with build number 39.2.A.0.417, which introduces the 1 February 2017 Google security patches. Likewise, the same security patches have rolled to the Xperia X and X Compact in the form of build number 34.2.A.0.311. Sony needs to be commended for updating these handsets with unprecedented speed. We will include FTF firmware links shortly.
Thanks Henry, Jozef, Jussi, Makis and Sándor!
