A month or two ago my Samsung Galaxy S-6 started making nearly constant notification signals, like every minute or 2. Any useful notifications were lost in the flood. I turned notifications off, but that's really unsatisfactory. I've gone down the Notifications setting page and turned them off for all but the very few I want, but none of them notify that much. The only app I have that might be notifying that often is Gmail, but I've turned its notifications off and the g**d**m flood keeps coming. Can anyone help?
