How to block contact in the phone Xiaomi Redmi Note

Modern Xiaomi Redmi Note smartphones have become an integral part of our digital life, but with convenience they have brought new challenges. One of the most annoying problems for users remains intrusive spam, cold calls from scammers or simply unwanted communication with intrusive interlocutors. The built-in mechanisms of the Android operating system in the shell of MIUI offer powerful tools to solve this problem, allowing you to effectively manage incoming traffic.

Unlike many other manufacturers, the Chinese brand has integrated the blocker functionality directly into the core of the system, making the process of protecting against unwanted contacts as simple as possible and does not require the installation of third-party software. The number lock on Redmi devices works at a deep level, preventing not only audio signals, but also vibration, as well as notifications of missed calls. This allows the user to remain calm and not distracted by information noise, which often disrupts productivity or rest.

In this article, we will discuss in detail all available methods of limiting communication with specific subscribers, you will learn how to use the standard contact menu, the capabilities of the Security application and hidden blacklist settings, and we will also discuss the nuances of blocking for different versions of firmware, which is especially important for owners of Redmi Note models, which may have differences in the interface depending on the year of release and the regional version of the software.

Use of the built-in “Contacts” application

The fastest and most obvious way to restrict access to an unwanted person is to use the functionality of a standard phone book, which is ideal if you need to urgently block the number from which the call or message just came, the algorithm of actions is intuitive and requires minimal touches of the screen, making it accessible even to inexperienced users.

To start, open the Contacts app or go to the Contacts tab inside the Phone app, find the name of the subscriber you want to block, or enter their number into the search box. After opening the contact card, look at the bottom of the screen or the three-dot menu in the top right corner, and that's where the key settings for the interaction with that subscriber are hidden.

In the menu that opens, you must select Block or Blacklist. The system may request confirmation of the action, warning that you will no longer receive calls and SMS from this number. Once confirmed, the contact is marked with a special icon indicating its status. It is important to understand that the lock through the contact card only applies to saved numbers, so for unknown spammers, this method requires the prior storage of the number in the device memory.

💡

If the number is not saved, add it to your contacts first by creating a new entry with any name, such as Spam, and then apply the lock.

Note that the interface may vary slightly depending on the version of MIUI. On some Redmi Note models, the lock button is placed in a separate menu under the gear settings inside the contact card. If you do not find the right item at once, carefully examine all available tabs, since the logic of grouping controls is often changed by developers to optimize the screen space.

Blocking through call and message log

Often, the need to block a call is created when a call arrives or immediately after it, when the number is not stored in the phone’s memory, in which case the most effective solution will be to use the call history. The call log in Xiaomi provides advanced functionality for working with incoming and outgoing connections, allowing you to manage subscriber access in just one click.

Open the Phone app and go to the tab that shows the clock or the handset history of the connections. Find the number you want to block. Depending on the firmware version, there may be a down arrow next to the number or an information icon (the letter "i" in the circle), clicking on this element will open a context menu or detailed information about the call.

In the option list that appears, select Lock the number. The system will instantly blacklist that contact. A similar mechanism works for text messages. If you are concerned about spam in Messages, open a dialogue with an unknown sender, click three dots in the corner of the screen and select lock, this action will prevent any further messages from this number.

Special attention should be paid to the function “Antispam”, which is often integrated directly into the interface of the call log. On Redmi Note devices with global firmware, this feature can be marked with a shield icon. Activating lock through this interface ensures that the number will be entered into the databases of the defender, which can help in filtering similar calls in the future if they come from other numbers of the same operator.

Set up a blacklist through the Security app

The central element of security management in Xiaomi smartphones is the pre-installed Security app, which is where the most flexible blacklist settings are concentrated, allowing you not only to block specific numbers, but also to create complex rules for filtering incoming traffic, a real command center to protect your personal space from intrusions.

Run the Security app (green shield icon) and search for the Antispam section. In some versions of the interface, it may be called “Block” or have a ban icon. Inside this section, you will see a list of all blocked numbers, as well as statistics of blocked calls and messages, and here is the button to add new numbers to the blacklist manually.

By clicking on the add icon (usually a plus or add button), you can manually enter your phone number or select it from your contact book. However, the main strength of this tool lies in the settings. Go to the anti-spam settings menu (cogwheel) to activate the lock of hidden numbers, foreign numbers or any unknown contacts that are not in your phone book.

Using smart rules in the Security app, you can create a virtually impenetrable shield, you can set up Do Not Disturb mode for a certain time of day, or you can activate blocking of all international calls if you have no relatives abroad, which turns your smartphone from a tool that can distract you every minute, into a device that works exclusively for you.

Managing blocked contacts and exceptions

Sometimes it is necessary to block the contact temporarily, and in other cases important numbers, such as a courier service or a doctor, can accidentally get into the blacklist. So the ability to manage the list of restrictions and make adjustments to it is a critical skill for the owner of Xiaomi Redmi Note.

To view the list of blocked numbers, go back to Security -> Antispam. This shows the full list of all restricted contacts. You can delete the number from this list at any time, restoring the ability to communicate. You just click on the number and select the unlock option or delete it with a swipe, depending on the interface settings.

The White List feature is a list of contacts that will make calls even if you have a full lock mode of unknown numbers or a Do Not Disturb mode, and you can add contact to exceptions through the anti-spam settings by selecting the appropriate section, which ensures that you do not miss an emergency call from loved ones, even if your phone is in hard filter mode.

⚠️ Warning: When resetting your phone to factory values, the blacklist can be cleared. be sure to back up important contacts and settings if you plan to flash the device.

Also, some carriers provide their own network-level locking services, which may conflict with phone settings, and if you notice that locked numbers are still passing, check if your carrier has an Anti-Detector service or similar services that can intercept call management.

Features of blocking in different versions of MIUI

Xiaomi’s ecosystem is constantly updated, and with each new version of the MIUI shell, the interface and location of the controls may change. Owners of Redmi Notes from different years of release may experience differences in menus. For example, in older versions (MIUI 10-11), the blacklist settings were more disparate, whereas in MIUI 12, 13 and 14 they were consolidated into a single security center.

Global ROMs often have their locking functionality cut short compared to China ROMs due to differences in data protection and telecommunications laws. Global firmware may not automatically update spam databases, which are active in Chinese versions. However, the basic manual blacklisting functionality works identically on all devices.

If you can't find the menu items described above, try searching by settings. Type the word "Block" or "Black List" in the search box for your phone's settings. The system will tell you the way to the desired section, which is especially important for users who have upgraded to a new version of the software and have not yet had time to get used to the changes in navigation.

Another feature is the work of locking in the mode of two SIM-On Redmi Note, blacklist settings are typically applied globally to all SIM cards, but lock history can be kept separately for each. Make sure that when you add a number to the lock, you don't limit it to just one SIM card, as long as your goal is to completely isolate the subscriber.

Decision and additional recommendations

Even if all instructions are followed, users may encounter situations where the lock is not working correctly, such as a blocked subscriber may hear the beeps even though the call does not pass, or messages may come with a delay, most often due to the peculiarities of the operator, which may try to deliver the message again or redirect the call to voicemail.

It is important to distinguish between device-level and operator-level locking. Locking in Xiaomi prevents notification to the phone owner, but the caller may hear the "busy" signal or long horns. If your goal is to make the caller hear "subscriber unavailable," this can only be achieved through operator services or flight mode, but then you will lose communication with everyone.

For maximum efficiency, it is recommended to combine methods: use a built-in blocker for known nuisance contacts, turn on the filter of unknown numbers to protect against spam, and install an application from the operator for additional filtering at the network level.

⚠️ Attention: Blocking a number does not mean that the sender will know that it is blocked, but the lack of response, eternal horns or undelivered messages (in the case of messengers) may prompt him to think about it.

Remember to update your antivirus and anti-spam database regularly in the Security app. Developers are constantly adding fraudulent number lists. The current database will allow your Redmi Note to automate and block new threats even before they bother you.

💡

The integrated use of the built-in MIUI tools and network services of the operator provides 100% protection against unwanted calls and messages.
