So I used to put music on my Samsung Solstice. When I plug it in, it says on my phone that it is charging and it is hooked up to my computer, but the symbol is black, not white, if you understand. It's like it's still reading it. When I used to plug it in it gave me 3 options like PC Studio Music Player and something else. Now it only charges. I really want to put more music on please help me
