I have an OEM Motorola charger. On the D3 several times, I have connected the D3 to the charger, and charged away. Then when I turn the vehicle off and then back on, the charger is still connected, but the phone is NOT charging. If I unplug the charger and replug, it still isn't charging. I have unplugged, then turned the screen off, and replugged, and on occasion that has started the charging again, but I haven't figured out a specific solution that works every time. Another issue is that it gets really hot when this happens. Anyone else seen this behavior and/or have a solution?
