Hello? Hello? This is getting old. Razr Maxx, Jelly Bean, 3rd replacement phone. Stock. I call someone and they can't hear me well or not at all. Call back usually better. Troubleshooting many ideas: Signal problems. No. Happens nationwide. (I travel for work). Mic hole blocked. No Voice privacy setting? Changed. Sound About App. Maybe helping. Not sure if the phone is falsely a jack plug in when it's not. Other people's phones? No. Cell or landline no difference. Sunspots? Any ideas appreciated. Not given up just yet-trying to not get replacement no. 4 possibly inheriting a different issue.
