How to pull out the blacklist of oppor 1 1s mobile phones?

Some advertisements, sales calls, etc. It is often inconvenient for us to come suddenly when we are working, living and resting. How to set it as "blacklist" to avoid being disturbed by it? Let me introduce the operation steps to you.

How to set a blacklist:

1, ColorOS 7 and above: phone book/dialing APP > dialing interface with ":"upper right corner > harassment interception > call interface, ":"upper right corner > (harassment) interception rules > blacklist > click "+"in the upper right corner to add blacklist confirmation.

2.ColorOS version 7.0-7.2 model: "Settings >; Security > harassment interception > blacklist > click "+"in the upper right corner to add the blacklist for confirmation.

Tips:

After being blacklisted, you will no longer receive calls and text messages from this number (contact). Previously generated call records and messages will be moved into harassment interception.

This answer applies to all OPPO models.
