Ever since I bought my wonderful car dock, I have had the same problem. No matter how long the phone has been in the dock, either an hour or 5 minutes, when I take the phone out it lags for anywhere from 15-30 seconds. My background image is visible but I cannot change home screens, open apps, etc....nothing.
I dont have a multimedia dock, so I don't know if this happens there also. I've tried killing any apps in the background, toggling gps and/or bluetooth, and existing the car dock app but nothing helps. Really frustrating when I get out of my truck and want to use my phone.
Anyone else have this problem? Ideas as to what it might be?
