Still, the Samsung Galaxy S III GT-9300 might be upgraded to KitKat after all. The Arabian branch of Samsung confirmed this in a Facebook post after it was questioned by a local user.

Be advised that the information is not thrustworthy and you should take it with a pinch of salt. In addition, if we take into consideration that the Galaxy S III is already behind the 18-month window for support, the rumors for its Android 4.4 update might turn out to be untrue.
