My Droid X2 is not rooted, but randomly restarts. Other times, especially when charging, it locks up with a black screen and won't do anything. Even the power button on top does nothing. Have to pull the battery to get it up and running again. Thought the update would solve it...nope. Went into the store a week ago - did the factory reset and started over - same issue. In fact, tonight, it rebooted twice within 5 minutes, just sitting on the end table next to me doing nothing. Called tech support earlier this afternoon, and they were so surprised mine was acting up, because NOBODY is having the same problem I am. So the warranty replacement phone is supposed to be here tomorrow...we'll see. Apple is looking more and more appealing.
