A new firmware build (23.0.1.A.1.43) has been certified by the PTCRB for the Xperia Z3 (D6653 variant only) and Xperia Z3 Compact (D5833 variant only). The previous certified build (23.0.1.A.1.38) has not been released up until now, so there’s no guarantee this new build will either.
The last update released for the D6653 Xperia Z3 SKU was version number 23.0.A.2.93 (Telstra Australia has seen the 23.0.A.2.108 build). The same applies for the D5833 Xperia Z3 Compact SKU, the currently released firmware is version number 23.0.A.2.93. The Xperia Z3 Dual (D6633) has also seen a new firmware build certified in the form of 23.0.F.1.82 (versus the current 23.0.F.1.74 software). We’ll let you know if Sony decides to release these builds.
