The latest version of Android is no rolling out to Samsung Galaxy S4 owners in India. The update version is Android 5.0.1 Lollipop, and this leaves Russia and India as the only places to receive this update for the Galaxy S4.
Everywhere else in the world is just listed as "pending" on Samsung's Galaxy S4 upgrade list. We will keep you informed as soon as it starts rolling out to other international markets and/or the North American markets.
