I can't explain why but I'll find that the Droid goes into silent / vibrate mode without warning. I don't know if this happens when I disconnect it from the USB but something triggers it. I'm looking at these forums. It's actually humorous. If this was Microsoft people would be ripping them for releasing an alpha/beta product. As it stands now, I can't believe how many issues Android has and the very slow response time to simple things, such as the awful and obvious call log bug.
