After the oppo k9 phone is unlocked, the interface pops up. How to turn off the weather?

Advertising pop-ups on OPPO 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.
