Reports have been hitting G+, and of course trickling down to blogs, that owners of the Xperia Z1 and Xperia Z Ultra on Canadian carriers Bell and Rogers have an update waiting for them. The update to the Sony device offers up a build number of 14.3.A.0.757 and brings with it Android 4.4.2 KitKat.
The update brings in KitKat , of course, along with performance an UI optimizations, a tweaked status bar and quick settings that are more intuitive and customizable and the new Xperia Themes addition.
If you haven’t seen the prompt for the update yet then head into settings > about phone > software update. Alternatively you should be able to plug the device into your PC and launch the Sony Companion software and check as well. If you do see the update wirelessly, be sure you have a stable Wi-Fi connection, a little time to download it and over 50% battery life to get it all installed.
