[AC Question]

How can I turn off all these notifications that I get on my Samsung Galaxy S6? I get about 300 notifications per day, most of them are of no interest of me. I tried several ways to turn them off but nothing works. Here are notifications that I get, that I want to have turned off:
- Mail (very important, I tried to turn it off under app notifications --> GMail, but it doesn't change anything)
- Weather (who cares about that? If I want to know the weather I look into the sky.)
- Roaming message (I know roaming is turned off, there's no need to tell it to me dozen times a day)
- GPS (Why would I care that my phone has lost the GPS signal?)

Others I want to keep:
- Messages
- What's App
- Airbnb
- ...
