I'm very confused by this problem and I've tried nearly everything short of a factory reset to fix it. The Problem: When I connect my phone to my computer via the USB cable all it does is charge. I've tried it on at least 3 different computers and recently installed the driver software on my main computer, and still nothing. The Confusing Problem: When I connect my phone to my car charger the USB options come up - choosing between Media Player or Mass Storage Device. This is the USB setting I have on my phone; I've tried changing it, and still nothing. I have no earthly idea why this happens. Any help?
