The Sony Xperia Z3 and Xperia Z3 Compact has a new software update around the corner, as a new build number has just been certified by the PTCRB. Currently, these handsets are currently running version number 23.0.A.2.105, but the new update would move this to build number 23.0.1.A.5.77. Given the change in build number, this could be more than just a bug-fix. However, it may be a carrier update. We’ll let you know if and when it starts rolling.
Xperia Z3 build number 23.0.1.A.5.77 certified for D6603 and D6653 variants
Xperia Z3 Compact build number 23.0.1.A.5.77 certified for D5803 and D5833 variants
