A new firmware update with build number 14.5.A.0.283 has been released for the Sony Xperia Z1 Compact (D5503). The update has so far only been released for T-Mobile Austria and Telekom.de in Germany. However, users on these carriers were still rocking Android KitKat (14.4.A.0.157), so this update brings them a first taste of Android Lollipop. It is unclear whether this ‘283’ firmware will see a global release, the same build number has also been certified for the Xperia Z1 and Xperia Z Ultra, although those updates are not live right now.
