Dear Samsung users:
Based on your description, we recommend that you:
1. Check whether you are using a third-party music player software. If so, please uninstall and delete the software and try using the built-in music player.
2. If it still exists, it is recommended to enter Settings-Application Manager-All-Music Player (Music)-Clear Data.
3. Please back up the data in your phone (contacts, text messages, pictures, etc.), and then restore the factory settings (Settings - Reset - Restore factory settings).
If the problem persists, please bring your purchase invoice, repair card and machine to the Samsung Service Center, where professional after-sales engineers will help detect it. For the specific service center address, please visit: .samsung.com/support/ServiceLocations.asp
