Call static

[AC Question]

When I'm in a call with my friends they hear static on their side but I don't hear the static we are thinking it's my phone if it is is there a way to fix it

That could be anything from a problem your carrier is having to a bad motherboard in your phone to a bad connection to your mic. IOW, anywhere from a few million dollars to a few dollars. There's no way to determine where the problem is without bringing the phone into your carrier.
