Ok, so I have tried searching the forum for an answer, but haven't found one..... When my wife makes a call and proceeds to do stuff on her phone, the other caller can hear every time she presses a button, all of the music of any app she is in, etc. She has a 16GB Galaxy S4 from T-Mobile My 16GB Galaxy S4 from AT&T does not do this, so it doesn't appear to be a phone issue, all that I can think of is that there is some setting somewhere. I have already checked the receive alarm and message notifications while on call and that is turned on for both phones, so I don't think that is an issue. Anyone have any ideas?
