How does oppoa9 close the advertisement promoted by 2345 Weather King?

Advertising pop-ups on mobile phones are generally caused by downloading software with malicious plug-ins or cell phone poisoning. In this case, you can try the following:

1. Observe whether there is any software downloaded before this happens on the mobile phone, and then uninstall the corresponding software.

2. The mobile phone is connected to the computer for antivirus.

3. After backing up important materials (contacts, multimedia files, etc.). ), restore the factory settings.

This answer applies to all OPPO models.
