Where is the phone number blacklist of oppo A 55?

How to set up a blacklist

Some advertising and sales calls often come suddenly when we are working, living, or resting, which brings us great inconvenience. How can I set it as a "blacklist" to prevent it from disturbing me? Let me walk you through the steps.

How to set up the blacklist:

1. ColorOS 7 and above models: ""Phonebook/Dial" APP > Dial (call) interface, ":" in the upper right corner > Harassment interception > Call interface, ":" in the upper right corner > (harassment) interception rules > Blacklist > Click the "+" in the upper right corner to add the blacklist and confirm.

2. ColorOS 7.0-7.2 version models: "Settings > Security > Harassment Blocking > Blacklist > Click the "+" in the upper right corner, add the blacklist and confirm.

Warm reminder:

After being added to the blacklist, you will no longer receive calls and text messages from this number (contact). Call records and information generated previously will be moved into harassment interception.

This answer applies to all OPPO models.
