I'm trying to figure out what my phone is doing all the time. Fo some reason, when I check my phone, more than 75% of the time the little circle is twisting in the top right next to the icons.. I'm not running any apps in the background, I checked my internet connection and when I turn on airplane mode the icon stops. Turned off wifi for loads of apps but I couldn't find the problem. Any ideas..? It's really annoying to think it can be using quite some data in the background..
