If it ends automatically, it is estimated that your mobile phone has some optimization software, such as some optimization masters, or similar mobile phone task management or process management software, which has the function of automatically ending tasks. In this case, when your phone locks the screen, it will end the program you are running, which will also save power for your phone.
