I just got my Droid replaced today for the 4th time. And a few minutes ago, I just got a notification sound that kept going. Except that instead of making the actual sound, it was more staticy. The phone wouldn't respond and I had to pull the battery. Any ideas what it could be? I'm using the built-in notification sound. I'm getting so sick and tired of having constant problems and am ready to just turn it in and demand a full refund and just go with a "normal" cell phone.
