Sony has released a new software update for the Xperia Z3 and Xperia Z3 Compact that moves the build number from version 23.0.A.2.105 to 23.0.1.A.5.77. The update is currently rolling for the D6603/D6653 variants of the Xperia Z3 as well as the D5803/D5833 Xperia Z3 Compact variants.
Sony has not released the changelog for this new Android 4.4.4 KitKat software build, but we are told it includes the Portrait Retouch mode for the camera (as in the Xperia C3), plus a slightly newer version of the home launcher. However, we haven’t verified this for ourselves. If you have downloaded the update, let us know your thoughts in the comments below.
