Hello, I have an issue where the 4G icon keeps appearing in the notification bar next to the signal strength icon, even when I have all data turned off, roaming and otherwise. Sometimes it appears when I have Wifi activated, and it keeps draining my mobile data when I don't want it too. The icon will sometimes appear with gray arrows, or with one or both arrows white, and if I try to load a webpage, it will tell me I am not connected. I want to know how I can stop this from happening.
