If you are using the Sony PC companion you can update your Xperia Z3 flagship mobile with a fresher Android 4.4.4 KitKat build namely  23.0.A.2.105. The new build comes with bug fixes that make it a more stable software experience over the last. The new firmware is not rolling out OTA as the Japanese multinational conglomerate corporation stopped the service. However, as long as you have a Windows-based computer you can install the new build direct from the PC. Alternatively, users with the model number D6603 can install the file here using the official flash tool.


Android 4.4.4 is made famous for its fix brought in for the Open SSL security scare that came about with the previous Android 4.4.3 and the revamped phone dialer. In addition, it carried framework and other security enhancements, stability improvements, accuracy improvements and more. We haven’t seen many features in the final stages of KitKat since the Android 4.4.2 software rolled out to devices.

The build is rolling for the United Kingdom region and there’s talk of it hitting other parts of Europe although unconfirmed at this stage. Make sure you backup your smartphones before starting the upgrade so that you don’t lose any of your important data including phone contacts, music files, videos, pictures and more. use applications such as SMS backup + to help you make copies of the text messages.

Next up for this smartphone is the Android L software that is currently in the developer preview stages. The real deal is set to release sometime during November of this year. Since the Z3 came out of the box with the final stages of the chocolate software, we are certain that it will receive the Android L at some stage. Flagships are never to far away from the top of the pecking order. However, Sony’s reliability with updates is weak, therefore you should keep your eyes peeled for additional news on the matter. For now, there’s another month to go before we start identifying stages rollouts of the Nexus range that Google loves looking after first.
