How does note4 in Redmi set up harassment interception?

I always use the mobile phone housekeeper to intercept them.

It is very convenient to install a mobile phone housekeeper first.

Then find the harassment interception function and choose the permanent residence.

Just keep following the prompts.

When we receive a "ringing" call, we can check it through the "Dialing" interface, as shown in the figure, and click to enter the number details interface.

After entering the "stranger contact" interface, the specific time or other information of this "one tone" call will be displayed. Click the "More" button.

From the open "More" extended panel interface, we can directly click the "Add Blacklist" item to reject this "one tone" call.

Next, a prompt window "Are you sure you want to blacklist this number" will pop up. Click "OK" directly to add this number to the blacklist.

What if the "blacklist" phone is managed? Enter the "Settings" interface of Xiaomi 4 and find the "Security Center" item to enter.

After entering the "Security Center" interface, click the "Harassment Interception" item in the "Settings of each functional module" column to enter the detailed setting interface.

From the opened "Harassment Interception"-"Settings" interface, click "Blacklist Number" to enter the detailed number setting interface.

In the "Blacklist Number" list, click the corresponding blacklist number, and an extended menu will pop up, where you can perform related operations on the number.

At the same time, we can also set "Call Interception Ring Back Tone", as shown in the figure. Click this item to enter the detailed setting interface.

From the opened "Disturbance Interception Prompt Tone" interface, you can set the prompt tone for the other party to make a rejected call, including "Busy Tone", "No Number", "Off" or "Stopped".
