Samsung Galaxy S3 LTE
Samsung has released Android 4.4.4 update for Galaxy S3 LTE Samsung

The original international Galaxy S3 (I9300) variant was missed out of Samsung's KitKat listing as the handset has reached the end of 18-month support period from the manufacturer. On the contrary the LTE model, having had 2GB RAM launched a few months later, is able to support the platform upgrade.

Samsung has now started seeding Android 4.4.4 firmware update for the LTE model bearing model number GT-I9305N in Nordic countries.

The update bumps the build version to I9305NXXUFNI4 along with various KitKat features including wireless printing support, faster performance, reduced memory consumption, white status bar icons, full-screen lockscreen album art, updated Samsung apps, closed caption support and general stability improvements, according to Sammobile.

The update will take some time reach all the regions across the globe. To check the availability of the firmware navigate to Settings> About phone> Software update> Check now.
