There are small advertisements under the mobile phone to open the app.

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

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

2. Standby interface-slide down the curtain at the top of the screen-find an advertisement message and hold it down-it will prompt the application "-click the check box in front of" Cancel displaying notification after entering ".

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 factory settings (enter phone settings-reset-restore factory settings).

If the problem of restoring factory settings still exists, it is recommended to send the mobile phone to the nearest service center for testing and further processing.
