What about the old automatic promotion of small smart air?

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. Standby interface-slide down the top screen-find an advertisement message and hold it down-it will prompt the application-click Enter to cancel the check mark in front of the notice.

3. The automatic pop-up advertisement push information is the push information of the downloaded third-party software. You can disable the information push function through this software setting option.

4. If it is invalid, it is related to the downloaded software, and the corresponding software can be uninstalled and deleted.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset-restore factory settings). The problem of restoring factory settings still exists. You can send your phone to the nearest service center for testing and further processing.
