1. Check the settings of the music player to see if it is set to lock the screen to stop music. Just restart the player after the change.

2. Check whether the third-party security software is installed on the mobile phone, and see whether the software automatically sets the screen lock to clear the applications running on the mobile phone. Set the cancel option in the software, and you can do it.

generally, the program will not end automatically after the screen of a mobile phone is locked. If it ends automatically, it is estimated that the mobile phone is equipped with some optimization software, such as some optimization master, or similar mobile phone task management or process management software. There is an automatic task ending function in it, in this case, the running program will be finished when the phone locks the screen, which is also to save electricity for the phone.

If you don't want a program to end after the screen is locked, you can just add the tasks you want to keep to the filter list (automatically ending tasks means closing tasks other than the filter list when the screen is dormant), or simply cancel the item of automatically ending tasks, so you don't have to worry about turning off some running tasks when the screen is locked.
