Update to KitKat finally arrives for Samsung Galaxy S4 LTE-A
The update comes five months after the South Korean variant received KitKat. The international model of the Samsung Galaxy S4-LTE had been powered by Android 4.2.2 before receiving the newer Android build.
Build number XXUCNG3 has been seen in the Nordic region, in such countries as Sweden and Finland. The update brings the white icons to the phone's status bar, a new lockscreen with a shortcut to the camera, support for wireless printing, full-screen album art, newer versions of Samsung apps, improved battery life and an overall better performance for the phone.
Since the update is coming OTA, it is being sent out in phases. That means you need to practice some patience. If the update hasn't hit your phone yet, don't panic. Samsung hasn't forgotten about you.
