Ok, so I went out of town the other day, about a 3 hour drive. I had my D2 on the moto car dock and was using the Navigation app that comes with the phone. After about 2.5 hours, a warning popped up on my screen "Temperature Alert!" and advised me to basically turn off the phone. I pulled it out of the dock and it was extremely hot. Another thing is, even though the dock was plugged in, the battery was completely dead with 5% remaining. It was not a hot day and my dashboard was not hot either. I am just wondering how this could happen? Another time it gets really hot is while downloading. I was downloading a 100+MB file a few weeks ago, and put the phone back into my pocket as it was going to take awhile. My leg felt liked it was getting burned and I pulled the phone out and it was so hot I had to turn it off. My leg felt sore for a few days. Is this just a problem with the D2, or is it my phone. I can't say I ever really noticed it before, but maybe just shrugged it off.
