My brother called me twice yesterday and had no trouble understanding what I was saying. Later in the evening, he called again, only this time he said I sounded like the guy from Scream or Gary Sinise when he calls Mel Gibson in Ransom. I called my voicemail and recorded a message and confirmed that I did sound like what he was describing. I took my cover off, restarted the phone, and everything was back to normal. I did notice that while this trouble was happening, I was not able to record anything on the voice recorder. But after the steps above where completed, I was. That was the first time I had anything like that happen, and I got this phone on May 1. Everything seems normal this morning. Anyone ran into this trouble to let me know if I should do anything, or just wait and see if it happens again?
