Can we upgrade the Samsung S3 with the latest Kitkat 4.4 version. IS this possible to be upgraded? What are the devices that can get this update? If we can upgrade can I know all steps to achieve this?
You would be able to upgrade your Samsung Galaxy Note 3 to Android Kitkat in near future. The upgrade is under testing phase and would be released soon. You would get a notification regarding it. You would be able to upgrade through Samsung  Keys. Presently, Nexus 4 and Nexus 7 are also in the process of getting an upgrade. But, till date no upgrade for Android 4.4 is released.
