Why do Android phones have advertisements?

This situation shows that your information has been leaked.

If the mobile phone often automatically pops up push information advertisements, it is suggested that:

1. Open the notification bar and check whether there is the word "Clear" on the upper right of the notification bar. If yes, please click to clear the information in the notification bar.

2. Slide down the screen top curtain in the standby interface, and find an advertisement message to press and hold to prompt the application. Click enter and remove the check mark in front of the notification.

3. The automatic pop-up advertisement push information may be the push information of downloaded third-party software. It is recommended to disable the information push function through this software setting option.

4. If it is invalid, it may be related to the downloaded software. It is recommended to uninstall and delete the corresponding software.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings (enter the phone settings, reset and restore the factory settings).

Maybe you downloaded some software, and there are third-party advertisements in the software. If you don't want to display them, you can set the software to disable the advertising function. If it is really related to software, you can uninstall the software decisively.
