Sony Xperia S Car Charger Problems, Please Help!

Hi RUBY0151. Welcome to Android Forums. Thanks for joining and I hope we can help you with your charger problem. I can't imagine what might be wrong between charger and phone. There should be no special setting to make it charge from your car. If it's charging at home, it should charge in your auto. You might want to ask the other users of your phone if they have experienced such a problem. They can be found by following this link: Sony Xperia S - Android Forums
Best of luck to you and thanks for joining Android Forums. I hope you enjoy your time here and that these forums serve you well.
