Finally, the phone needs to be restarted.\Note: Not every app can become a system app. If there is a prompt like 'This software may temporarily have an error report' before restarting, don't modify it and delete the installation package instead.
Similarly, you can delete system pre-installed apps in this folder, but apart from the odex file, the apk must be deleted at the same time. Before deleting, you should check on Baidu whether it can be deleted, to avoid causing problems with your phone . Likewise, after deleting, you need to restart.
