Late last week, I noticed that my WiFi signal arrow (pointing up) is *always* active on my Lumia Icon. This did not happen before (it would only come on when I was clearly requesting data). I have WiFi Sense turned off. I reset my phone in case it was some bad app behavior, and same thing happened. When I'm out of WiFi range, the cellular data is always on (at least it shows the little arrow by my signal strength).
I even went over to a friend's house on the off chance it was something with my router (before I paid attention to the cellular data usage), and the same thing happened.
I've turned off Location and everything else I can think of, and the icon always appears to be sending data.
Turning off using data over a cellular network, does keep it off, but then I don't get useful things like email.
Looking at the App Usage with Data Sense, there's nothing sending any significant amount of data (as expected for my usage).
What is happening? What is being sent or received? Is this some glitch of the icon?
As I said, this appears to be new behavior for my Icon.
