How to set the OPPO mobile phone whitelist

If you want to set the information whitelist, I suggest you try it according to the following operation methods: 1. Enter the phone book-Settings-Harassment interception-Switch on-Blacklist-Add Blacklist; 2. White List-Add White List-Add Contacts; 3. After joining the information whitelist, you can normally receive the short message of this contact in the information interface. At present, it can be operated and implemented in ColorOS 1.2 and later versions, and it can also be set by software such as Kingsoft Mobile Guardian.
