Hey all. Been having the same issues. This is my second D2G, and tomorrow I'm taking this one back for another replacement. I'm not so sure #3 will be any better since both have had the overheating, freezing, and slidelock reboot.
That plus the typing errors (that also occur on the Pro and X so it's a Motorola thing, not a D2G thing), the push email that really isn't (also on the Pro), the taking 2-3 taps to get the main keys and the call key to work... it's Motorola passing off a bad OS or bad hardware or both.
I keep seeing references to the overheating and freezing possibly being caused by faulty a app. But I have ZERO added apps on this one after a Hard Reset this week, and it's STILL doing it. SO if it's a bad app, it's one of the pre-loaded ones THAT YOU CAN'T UNINSTALL. And now, the screen goes black for 10-15 seconds after a call and it's not charging past 50%. So frustrating!!!
