Earlier promises from Samsung had the Android 4.3 update beginning for the Galaxy S4 in October. And well, it looks like they are going to be keeping to that schedule. Samsung has begun rolling out Android 4.3 Jelly Bean for the Galaxy S4 (model GT-I9505). Just to clarify, the I9505 is the international model. Or in other words, those with a carrier branded Galaxy S4 likely still have some time to wait.
