I've noticed over the past week or so that when my 1520 is connected to my home Wi-Fi the activity arrow is on solid. It was never like this before and I'm pretty sure it doesn't do this on works Wi-Fi. When I disable Wi-Fi the ATT LTE connection doesn't show activity constantly. Any ideas what's going on? It is literally showing network activity all of the time. It doesn't blink off now and then at all. The phone seems to be working properly and data sense doesn't show anything using tons of data over Wi-Fi.....
