So it is not in do not disturb mode and the silencer is not on so I can't figure it out- and it notifies me when new texts come in but if I try to call out or listen to something there is not volume?? anyone have any ideas or do you think a restore will fix the problem?? the weird thing is it was working fine like two hours ago and I haven't done anything weird like surf the net or get an weird email that might have given the phone a virus??
