I want to pick up an S7 and am debating between an unlocked AT&T model and the international model. The US variant has a Snapdragon 820 whereas the international model has an Exynos 8890. After searching, I've found that the 8890 is faster overall and comes paired with a better audio chip, but has a slower GPU. The international model also doesn't support Samsung Pay. Is that a major feature that's very useful? Or is it another one of Samsung's experiments that will likely be dropped in the next generation or two? Does Google Pay work in the US on the international model? Also, as far as updates are concerned, will they be released more frequently and in a more timely manner on the international model vs the AT&T variant? Any extra input would be much appreciated. For the record, I don't like fiddling around with rooting or custom ROMs. I'm leaning towards the international model right now and understand that it doesn't come with a warranty.
