I don't get any switch to enable or disable that. Perhaps this is because I don't have any of this cloud stuff enabled or set up. Nor do I want to enable or set it up.
I also get notifications, with a sound, a few.times per day asking me to set up some cloud crap. And when I long press that notification, to try to shut it off, I get a message saying it cannot be shut off. Most annoying!
Maybe this is an AT&T thing.
I may visit the store where I got the phone a few years ago and see what they say.
