How to set up unfamiliar text message interception on oppoa11x

How to set up harassment interception:

1. ColorOS 7 and above models: "Dial-up> Upper right corner ":" > Harassment interception> Upper right corner ":" > Interception rules >Call blocking/SMS blocking".

2. ColorOS 7.0-7.2 version models: "Settings > Security > Harassment Blocking", click on the blacklist, you can select from the address book or manually enter the number you want to block.

3. ColorOS 3.0-6.2 version models: "Settings > (System Applications) > Phone > Harassment Blocking > Blacklist" to add or delete blacklist contacts.

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.
