Where to find a blacklist in the phone Xiaomi Redmi: all ways to access

The blacklist on Xiaomi Redmi smartphones isn’t just a feature to block unwanted calls; it’s a powerful tool to protect against spam, scams and annoying contacts that many users don’t use to the fullest. Unlike standard Android devices, Redmi phones have their own lock implementation with advanced settings hidden in the depths of MIUI.

The problem is that the manufacturer regularly changes the layout of this section depending on the version of the shell, where in Redmi Note 12 the blacklist is in one menu, in Redmi 10 it is in another, and in older models on MIUI 11 it is generally necessary to search through the Security app. We have collected current methods for all versions of the firmware, including hidden methods of access through the engineering menu.

What is a blacklist on Xiaomi Redmi and how does it work?

The blacklist in Xiaomi Redmi is a system mechanism for blocking incoming calls and SMS from certain numbers. Unlike the standard Android blocker, it works at the MIUI firmware level and has several key features:

• 📞 Not only does it block calls, but it also blocks calls. SMS/MMS message
• 🔍 Filters spam numbers on the Xiaomi database (if synchronization is enabled)
• 📱 Works even when the Internet is turned off (blocking at the level of the communication module)
• 🔄 Can automatically add numbers from spam call logs

It is important to understand that the blacklist does not block numbers in messengers (WhatsApp, Telegram) – it works only with traditional calls and SMS. It also does not affect notifications from system applications or Google services.

The latest versions of MIUI 14/15 have introduced a Smart Lock feature that analyzes subscriber behavior, for example, if a number calls you 3 times in a row for 5 minutes, the system can automatically prompt it to be blocked.

Official way: where to find a blacklist in standard settings

The easiest method is through the standard Phone app, which is relevant for Redmi Note 11/12/13, Redmi 10/9 and other models on MIUI 12-15:

1. Open the "Phone" application (pipe icon)
2. Click on three dots in the upper right corner → select Settings
3. Go to the section Block numbers or Blacklist (name depends on version)
4. Here you will see all the locked numbers and can add new ones.

On some models (Redmi 8, Redmi 9A) the path may be different:

Phone → Magazine → Settings (cogs) → Blocking and Identification → Blacklist

If you can't find this section, check the version of MIUI in Settings → About Phone. On old firmware (MIUI 10-11), the blacklist could be hidden in the Security app.
