1. Standard blacklist through phone settings

The most reliable and versatile way is to use the built-in blacklist feature in MIUI, which blocks both incoming calls and SMS from unwanted numbers. The interface may vary slightly depending on the firmware version, but the general logic remains the same.

To add a number to the blacklist through system settings:

1. Open the Phone app (the tube icon on the home screen).
2. Slip on the three dots in the upper right corner and select Settings.
3. Go to the Blocking Numbers section (or the Blacklist in older versions).
4. Click Add a number and select one of the options: 📞 From call logs - blocking the last incoming / outgoing. 📇 From contacts - a choice from the phone book. ➕ Manual input – for numbers that are not in the journal.

Block messages

Once added, the number will automatically be placed on the blocked list, to check or edit it, go back to the same settings section, and you can set exceptions here, for example, allow calls from hidden numbers or specific contacts even if they are blacklisted.

Check the version of MIUI in Settings → About the phone

Update the Phone app to Google Play (if available)

Make a backup of contacts in case of an error

Make sure the number is in international format (+7...)

2. Lock through the call log (quick method)

If you're bored of a particular number that just called, you can block it right from the call log, without having to click the menu, and it takes only 10 seconds, and it's perfect for emergencies.

Instructions are Step-by-step:

1. Open the Phone app and go to the Journal tab.
2. Find the number in the list and tap it to open the details.
3. In the upper right corner, click on the icon. ⋮ (three dots) and select Block the number.
4. Confirm the action in the window that appears. Optionally, you can tick the “Report Spam” box – this will help other Xiaomi users avoid calls from this subscriber.

⚠️ Note: If the number is displayed as "Unknown" or "Hidden", the standard lock may not work, in which case you will need to use third-party applications (about them in the next section).

This is convenient because it doesn't require remembering numbers -- just one touch -- and it applies to all future calls and SMS messages from that subscriber.

💡

If the spammer number starts with +79xxxx, try adding it to the blacklist in 89xxxx format – sometimes this helps to block both types of dial.

3. Use of the "Security" application for extended locking

The Security (Shield Icon) app in MIUI offers additional tools to protect against spam, not only blocking numbers, but also configuring SMS filtering, checking apps for viruses, and even enabling Do Not Disturb mode for individual contacts.

How to block the number through Security:

1. Open the Security app (usually located on the home screen or in the Tools folder).
2. Go to the section "Number Lock" (may be called "Antispam" in the new versions).
3. Add to the blacklist and select the source (login, contacts or manual input).
4. Activate options: 📵 Blocking calls for voice calls. 💬 Blocking messages - for SMS. 🔔 Notify about blocking – to see attempts to communicate in the log.

The advantage of this method is that you can block a lot of things, for example, you can select multiple numbers from a log at the same time or import a list from a file, and you can also get statistics on blocked calls, which will help you track the activity of spammers.

💡

The Security app is the most powerful blocking tool on the Redmi Note 7, as it allows you to manage spam centrally and see statistics.

4. Contact blocking (for existing subscribers)

1. Open the Contacts app.
2. Find the right contact and tap it to open it.
3. In the upper right corner, press on ⋮ (three points) and select Lock.
4. Confirm action. Optionally, you can mark Delete all messages from this contact.
