A new software update has unexpectedly landed on the Xperia Z3 (D6603) which moves the build number from version 23.0.A.2.93 to 23.0.1.A.5.73. This is for those on “Generic Global” firmware and has been arriving OTA (not via PC Companion). Users that have downloaded the update have not noticed any big changes, however if you have downloaded the update let us know your impressions below.
Thanks @smannstein!
