My mobile phone housekeeper can't intercept blacklisted phone calls and text messages from strangers. Even if I set them up, I can't stop them.

Open the mobile phone housekeeper-security protection-harassment interception-settings-smart mode. Generally, spam calls and messages with more tags will be intercepted. You can also add a blacklist after receiving spam calls, or you can manually add phone numbers to the blacklist.

I hope everyone can adopt my answer, thank you.
