Xperia Z1 Compact D5503 got its first android 4.3 14.2.A.1.142 firmware update yesterday which seems only a minor bug fixing update though no specific changelog is spotted so far from any user. Same 14.2.A.1.142 firmware is also expected to hit Xperia Z1 and Xperia Z Ultra but chances are very low as we are expecting direct android 4.4.2 KitKat 14.3.A.x.xxx firmware to roll on these two devices.

Just now Chinese Xperia Z1 Compact M51w which is yet not available for sale, saw Android 4.3 14.2.A.1.146 firmware update. As when it will be available for sale, users will be getting this update hopefully or which ever update is available then.

Kernel build date of both 14.2.A.1.142 and 14.2.A.1.146 firmware is same i.e. 9 Jan 2014.
