I bought the Galaxy SIII, so that I could upload my MP3's to it.
I had a very difficult time trying to get the phone to connect to my pc
because it lacked having the proper drivers.
Finally, I went to Samsung's web page, and found the drivers needed
to do this. Once I had the correct drivers, I had no problems managing all of
the phones content with my pc...
I hope that this post may help someone else that may be encountering this problem.
