Does the questioner want to ask "What should I do if there is a scratchy sound when listening to DXD music on my mobile phone?"
1. The volume is not turned on, and the phone is set to vibrate or mute. Just turn off the phone to mute and vibrate.
2. The mobile phone has a software failure due to a system bug. If the mobile phone system can be updated, update to the latest version to see if it can be solved. You can also back up your phone’s data and then restore it to factory settings.
