Hope this is the right place, im new here. Ive had my 8330 for about a month now with sprint. ive put quite a bit of music on my phone. My songs are in my media player as well as the player that is provided in the sprint music store. With headphones, i did not have a problem using them in the beginning, but now, my headphones only work with the media player and not the sprint music store player. The store player automatically goes to the phone speaker. Any help please?
