Samsung just recently began to roll out its Android 4.4 KitKat for the Galaxy Grand 2 smartphone. All the features available on Android 4.4.2 will be pushed to the firmware for the smartphone including the recently updated TouchWiz launcher.
The new firmware is available for download with just about 360MB. The first country to be getting the update is India. Both the single and Dual-Sim Galaxy Grand 2 devices would be part of the KitKat update worldwide pretty soon.
