For some reason when I plug my phone into my computer with the USB cord it does not read it. I have never had this problem with a Android phone before. All I did was plug it in and my SD card files would pop up and I could add whatever stuff to my SD card that I wanted. All Im trying to do is put pics from my computer on it and all of my music. Someone please help. Its a Sony Vaio windows 7 pro 64-bit in case you need to know.
