That's the "Data Saver" symbol. Mean's you've exceeded a limit on your data usage. Best case is that your personal device's setting is at default, something small like 2G. Worst case is you actually broke your plan limit and now owe Verizon Sprint Tmobile etc moneyz.
Data saver. It restricts some apps running in the background unless you are using an app.
It saves battery life. You should be able to shut it off. Swipe down and it should be there in the drop down window.
