a guy in my office has a VZW galaxy s8 and i have one on XM. The updates seems to be only a day behind Verizon's. That being said Samsungs commitement to updates seems to be non-existant and getting them in the US seems to not be a priority at all. The S8 has Oreo all over the world, but not even a rumor as to a US release date. The Carrier can't do anything if the manufacture doesn't send it to them. I'm strongly considering a google manufactured device next round for this reason.
