I LOVED my Samsung Captivate Galaxy S until I plugged it into my computer. I have spent way too much time trying to get Windows Vista 64 bit to even recognize the phone. I downloaded driver from Samsung, but when I unplug phone, it usually doesn't find the phone again. This is what I have tried. Settings-applications-usb settings-mass storage then I changed usb ports Tried Samsung Kies, but kept having errors. Finally uninstalled because I read it is not compatible in the US. Maybe I need to unistall and reinstall driver. Does anyone know how to do this correctly? I downloaded it as a zip folder. Then chose setup and installed. When the phone is finally recognized by the computer Windows Media Player, Itunes Helper, or DoubleTwist all do not see the phone. I don't like my phone right now.
