I seem to have an issue that Samsung can't answer and I am trying to reach out to anyone who may be able to help. I am trying to use the preloaded app "Group Play" on my Galaxy Note 2...I can share pictures with people who are signed in my group, but when we go to share music I have no files to share. (When I say share I mean the way the app says it can share. By one phone being the main source of music and the other phones to be speakers). The thing is my daughter has a Galaxy s3 and hers is doing the same thing. What are we doing wrong? Why will my music files not open?
