How to set the notification bar not to display the message content?

Take Huawei Glory 20Pro mobile phone as an example. The setting method for not displaying short messages in the notification bar is as follows:

Open Huawei's mobile phone and click Apply in the settings. After entering, click Application Management and select Information. After entering, click Notify Management. Click to turn off the option to allow notifications.

First, from the application installed on the mobile phone

For example, a learning software is installed on your mobile phone, such as memorizing words or learning Chinese characters. You go in and learn some knowledge every day. In this case, if you miss a day because of some other things, you won't punch in on time to study. Then, the software will push you a notice at a specific time and display it in the notice bar to remind you to punch in and study on time. When you click this notice, the system will open this software and automatically enter the sign-in interface. And this kind of notice is a local notice.

Second, from the mobile phone system.

This should be more common. For example, when the battery of your mobile phone is low, a notice will pop up in the system notification bar to remind you to charge. For example, when your mobile phone is connected to a computer through a USB cable, a notice will pop up, prompting you to choose charging only, file transfer, or other options ... The mobile phone system pops up such a notice and displays it in the notification bar, which is the system notice. Strictly speaking, this kind of notice is also a local notice.

Third, push from remote services.

This kind of notice should be the most common notice for everyone. Software installed in the mobile phone that needs to access the network. When your friends or people you care about send a new message, the developers of these applications will push the message to your mobile phone through their company's self-built server and network connection.

In addition, there is a push from the network, but unlike these applications, they come from the developers of mobile phone systems. For example, your mobile phone will receive a system update notice from the manufacturer after a while, prompting you to upgrade your mobile phone system. Only notifications received and displayed by the network can be pushed by the remote server.
