I recently had my original s4 replaced with another one & before I did the switch I moved all my music & play lists to Dropbox,thinking it would be an easy switch back to new phn. Instead now I have to move each song one at a time even though I placed the whole folder in dropbox. Can anyone help me resolve this or do I have to continue to do one at a time, smh. Thanks for any help & also looking to learn & get the best performance from my Gs4!
