I have a lot of static when talking on my Razr M. It doesn't occur every time, but it seems to be getting more frequent. The speaker seems to be fine because people say my voice sounds great, but I can hardly understand what they are saying. As a result of reading other posts, I started my phone in safe mode to see if an application was causing it, but it was the same ( static was still there). Any suggestion for what I should do now?
