I'm new to this, so I'm not sure if anyone else has had this issue or if it has been addressed. But, I'm not receiving a lot of phone calls. The calls aren't coming through while I'm on the web browser or Facebook. I'm not sure if any other apps are effecting it, but I'm certain those two are. It's driving me crazy. I shouldn't have to stay off of these apps in order to receive my calls. Plus, people always think I'm ignoring them! Does anyone know what's going on? If so, know how to fix it?
