Why are my S3 radios starting to have issues

[Page Tyler]

I have started having problems with all my radios. The phone has s loud static sound on every other call. At first I thought it was my signal but it happens at all different places with good and pour signals. Then the Blue tooth sound started cutting out. It will just dropping during mid call and will repeatedly reconnect during the day. When I change head sets it does the same. I tried my music and it cuts off and on or the controls don't work. This all started about 2 months ago and is getting worse. Does anyone know how to fix this problem?
