Huawei Glory 9x+pro mobile phone automatically hides after installing some software. What's the matter?

Select the option to enter the system process after applying management, and display it after viewing.

Open Settings, click Applications and Notifications, select the option to enter the system flow after application management, and then select Desktop to display all applications.

In order to avoid being unable to find the application from the home screen after misoperation, the system cancels the function of hiding the software and cannot hide the software through gestures on the home screen. If you want an application not to be viewed by others at will, you can use the application locking function to lock the application, if you don't want to display an application on the desktop.
