This problem should occur because the background is still running. There are two ways to solve it, one is to close it in the status bar, and the other is to directly enter the software and exit. ? If the machine automatically plays music, it is recommended:

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/Privacy/Personal-Restore factory settings).
