Annoying App Notifications

A couple of years ago I made the switch from Samsung to LG phones. I had the LG G3 prior to my current G4. I really have no complaints with LG and their products. Samsung never gave me any travel chargers, free batteries, micro sd cards or free leather backs with their phones. My only problem is with annoying app notifications. I turn them all off; one by one only to see that they've magically reappeared and changed their permissions. Is this an LG problem or an Android problem? Why can't I turn off all app notifications at once? Please help.
