This is because of caching shortcuts. As we all know, memory cards are not real memory, but external memory. When the program accesses, it will access the data of the memory card by creating shortcuts. If the memory card is used as storage space in the default settings of Netease Cloud Music, it will take up this quick access method. If you don't kill Netease Cloud Music Process after quitting, it will always be occupied. If another process is started, it will be considered closed, so it should be cleaned automatically in the background, and two softwares cannot be hung at the same time.
Now the memory capacity of smart phones is comparable to that of computers. If it is a memory problem, remember to kill the process after exiting and log in again. If not, you'd better format it to make it more compatible with the format of your mobile phone. If it still doesn't work, you should change your mobile phone. If there is enough memory, it can't be opened. It should be a question of authority. Just set it up at home in the mobile phone tube!
