So I have a problem. It happened out of nowhere. I went to try and make a call and my phone said "connected" but i could not hear any tone. Seconds later, the person i was trying to call, texted me saying that he answered and couldn't hear anything! Then i had someone call me and the call went through but when i answered, I could hear nothing. I don't know whats going on. Calls go out and they are received but I get no sound. I hear nothing.
