Well, it is still having trouble, and great to know before I purchase. It plays in Windows Media Player, I can copy another file from my laptop, into the phone and it will persist on not playing, surely it is the file...but how did it play other mp3s that did not work, with other players (android players) and yet Poweramp, I was starting to like it, then nope. But I shall, is media fire OK? Or just direct DL, idk if you can trust me
