I just got a call from Ningbo, Zhejiang, which seems to be a harassing call. I called once and then I hung up, and then I called again. After I answered it, I scolded him and hung up.

Hello, don't get angry at harassing calls. It's all meaningless.

I recommend you to try Tencent Mobile Manager.

This is a completely free security management software.

After installation, enter the black and white list of security protection-harassment interception settings, and you can add the corresponding number.

You can also back up the black and white list.

Moreover, it can intercept the phone that hangs up as soon as it rings and block it.

Of course, you can also customize the interception mode.

hope this helps
