I was wondering if anyone else is having problems with this, I've only had my Motorola Droid a couple days now, and whenever I'm on a call it will randomly mute. I won't realize it until the person on the line starts saying "hello?" and the only way I've been able to fix it is to hang up in frustration and call back. The screen doesn't lock during the call, so maybe my cheek is hitting the screen without my realizing? Anyone have tips on how I can keep this from happening? In all other respects I love my new phone, I'd hate to have to return it because of this.
