How to set a white list for OPPO mobile phones?

If you want to set the information white list, I suggest you try the following methods: 1, enter the phone book-Settings-Harassment Interception-Open-Blacklist-Add Blacklist; 2. Whitelist-Add Whitelist-Add Contacts; 3. After joining the information whitelist, you can receive the contact's short message normally in the information interface. At present, it can be operated in ColorOS 1.2 and later versions, and can also be set by software such as Kingsoft Mobile Guardian.
