This icon started showing up in my Android notification bar last week. I think it was after I used the Google Drive app for the first time (I had never opened this app before and was just curious).
Now the icon is there all the time, occupying valuable notification bar real estate – and not providing any useful information in return, as far as I can tell.
What is this icon? What is it supposed to be telling me?
Can I make it go away? If so, is there a reason not to?
