Got the October security patch update this morning!
Note (no pun intended), I have an unlocked Note 9 from Samsung UK!
Friend on Bell Mobility got the October security patch a few days back on his S7 Edge. He's also on Android 8.0 and Samsung Experience 9.0. He's not concerned with big OS updates because his feeling is, Samsung phones have lots of features to begin with. He's only concerned with the security patches. And he's got a point when he says, he doesn't notice anything new when he gets an OS update, he uses his phone just the same as he always did. So no big deal. But everyone can appreciate timely security patches. That being said, most of us will update our phones within 2-3 years anyways. So the endless OS updates argument, as I see it, really doesn't hold water anymore.
