What is the icon for that looks like a wheel with arrows pointing away on 3 sides and then beams coming out of it on the right? Im sure it has something to do with gps or something but when gps comes on you get the standar sat looking thing with beams, so what is this? It is always on and im sure its affecting my battery. I do have back groun data enabled however I also have any app set to use background data using its own settings for updating. Any info would be appreciated.
