My Droid has been acting weird. It rings the default phone ring when no call is coming in. And it's been making calls without me. I thought that it was a result of me not locking it when I put it in my pocket, but now I'm not sure. And the other day I couldn't unlock it until I powered it down and reset the logic. Otherwise, it appears to operate normally. Has anybody else had a problem with their Droid's OS. If so, what's the solution, a Verizon visit, and software patch? Help...
