2.ColorOS version 7.0-7.2 model: "Settings >; Security > harassment interception ",click the blacklist, you can select the number you want to intercept from the address book, or you can enter it manually.

3.Coloros version 3.0-6.2 model: "Settings >; (system application) > telephone > harassment interception > blacklist ",add or delete blacklisted contacts.
