Hot on the heels of the earlier update for Xperia X/X Compact owners which included the 1 October 2017 Android security patches, similar firmware is now rolling for Xperia XZ, XZs and X Performance owners. The new update moves the build number from 41.2.A.7.65 to version 41.2.A.7.76. Given the small change in build number, we don’t expect any other tangible improvements, but do let us know if we’ve missed anything in the comments below.
