There will be an advertisement push after the screen is locked. How to turn it off?

If you use a Huawei mobile phone, the third-party application of the mobile phone will push the advertisement after the screen is locked or unlocked. If you don't want to see the advertising interface, you can try the following methods to close it:

1. Confirm the application that generated the lock screen advertisement:

Take a screenshot in the advertisement interface (press the power button+volume down button at the same time), then enter the gallery to find the intercepted advertisement picture, click the circle I in the upper right corner of the picture to view the image path, and determine the application of the advertisement according to the image path (for example: path: memory/picture/screenshot/screenshot-20210624-1665438+).

2. Enter the setting interface and find the corresponding application shutdown notice:

Open settings, search to enter application management, find the previously confirmed application, click notification/notification management, and close notification permission. (After the notification is turned off, the normal message reception of the software may be affected. Please be careful. )

3. Check whether there is a setting button on the advertisement page. If yes, click and select the lock screen display to turn off.

4. Prohibit the application from using the floating window display: open the settings, search to enter the permission management, click the permission interface to open the floating window, and turn off the switch for the application that is not commonly used.

5. If you don't need to use the "Generate Lock Screen Advertisement" application, I suggest you uninstall it directly.

6. If the above methods still can't solve your problem, I suggest you back up your data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and then restore the factory settings.
