So I'm using a Samsung Galaxy S2, (I know) and I'm trying to transfer files from a computer to my phone, for music. I plug in the phone and it says connected as media device (on rare occasions it doesn't?), but the computer doesn't install it, so the phone doesn't show up under Computer (Windows,7.hereswhereit gets extra tricky. I have no computer, so I have to use a computer at a library. So there could be the problem right there. But on a few occasions it will show up, and then, there it is. Yay But of course there's still problems. It rarely shows me anything. I open the storage up on the computer, and it's blank, no files, no nothing. I've been able to do it twice before, that's it. I've tried to look for usb mass storage under settings, but its non existent on my phone. If yopu can,help.
