Samsung Galaxy S3 Future Updates

Aside from expected Android 4.3 firmware updates which contain bug fixes, Galaxy S3 owners may get segmented parts of Android 4.4 KitKat firmware soon via Play Store. Official Android 4.4 KitKat software from Samsung may take longer than expected as the company will focus first on Galaxy S5, Galaxy S4 and Galaxy Note 3. But having Android 4.3 Jelly Bean update is a sign of great possibility getting further updates in 2014.
