Managing unwanted calls is becoming a critical task for every smartphone owner. Owners of Xiaomi and Redmi devices often encounter intrusive advertising or spam that interferes with daily life. Fortunately, the MIUI shell installed on Redmi 9 has a powerful built-in tool to filter incoming connections. However, finding a place where the list of blocked contacts is stored is not always intuitive the first time.
The security system developed by the company's engineers is deeply integrated into the standard call app, which allows you to effectively block spammers without having to install third-party software. In this article, we will discuss in detail all possible ways to access the blacklist, you will learn how not only to view blocked numbers, but also to effectively manage them.
Sometimes users accidentally block important contacts or forget who they have put on the restricted list, and restoring access to these numbers requires a clear understanding of the menu structure. We'll look at the regular methods through the settings and hidden engineering codes that run on current firmware versions, and this knowledge will help you keep control of your phone traffic.
Access through the standard Phone application
The fastest and most reliable way to see which numbers are locked on your Redmi 9 is directly in the Phone app interface. Xiaomi developers have put the necessary tools in the call settings menu. To start, open a standard caller, which usually has a green phone icon on your desktop.
In the upper right corner of the screen, you'll see a three-dot icon or a gear that represents the menu. When you click on it, select Settings. In the options list that opens, you'll find the block-related section. In different versions of MIUI, it can be called "Block" or "Antispam," and that's where the unwanted subscriber database is stored.
Inside the lock menu, you usually have a switch and a list control button, and by clicking on the blacklist, you have full access to all the numbers that the system has automatically or manually entered into the ban database, where you can delete entries, add new ones, or clear the entire list with a single touch.
💡
If you don’t see “Block” in your call settings, try updating the “Security” app through the built-in GetApps store or Mi Store.
It is important to note that the visual design of the menu can vary slightly depending on the regional version of the firmware. Global versions of Global ROM often have an English settings interface, even if the language of the system is Russian.
Use of the Application Security
The second method of accessing the blocked number list on Xiaomi Redmi 9 is via the system application Security. This is a universal control center where all antivirus and security functions of the smartphone are collected. The icon of this application is a green shield and is usually located on the home screen in the Tools folder.
When you start the application, scroll down to the Antispam block. This module is responsible for filtering SMS and voice calls. When you go to this section, the system can request permission to access the call log, which is a normal procedure necessary for the filter to work correctly. In the upper right corner of the screen is the settings icon (cog).
Clicking on the gear will take you to the anti-spam settings menu, select the Blacklist option, open a window that lists all blocked contacts, and the functionality of this section is wider than in a simple call: you can set the rules for blocking, for example, to prohibit calls from hidden numbers or numbers that are not entered in contacts.
☑️ Checking the lock settings
The security module on Redmi 9 is designed to synchronize spammer databases, so if you allow cloud-based verification, the phone will check incoming numbers against an online database of known scammers, and the blocked numbers that are included in this database will also be displayed in the shared list, marked with the corresponding status.
⚠️ Note: Do not delete the system application "Security" and do not disable its operation through ADB, If you're not sure what you're doing, it can disrupt your calls and cause Android to crash.
Configure rules and filters of the lock
The effectiveness of locking depends not only on manually entering numbers, but also on the right rules. On Xiaomi Redmi 9, you can create flexible scripts that automatically decide who can be reached and who can’t, and this is especially true for those who want silence at night or on weekends.
In the locker settings menu, find the Lock Rules, where you can block calls from all numbers, from unknown (hidden) numbers, or only from those who are not in your phone book, the latter option is often referred to as the "White List" mode, where only selected contacts can call.
There's also a Do Not Disturb feature that's integrated with the blocker, and you can set up automatic lock activation from 23:00 to 7:00, at which time all incoming except those marked as Favorites will be reset or sent to the answering machine without making a sound.
Business users can use the region-code lock feature, so if you only get calls from your city, you can block all numbers that start with other codes, which requires careful filling in the number masks, but it gives you an excellent result in clearing traffic from advertising robots.
Use of hidden codes and engineering menu
For advanced users who haven't found the right item in the standard menu, there are hidden codes. Entering a special combination of numbers in the dialing field allows you to instantly go to the deep lock settings menu, bypassing several layers of nesting. On Xiaomi devices, this method works steadily.
Open the phone application and type the code ##4636##. This is a universal code for logging into the Android test menu, but it's the blacklist that you access. MIUI It is more often used to go through the settings directly, as direct USSD-The blacklist codes can vary from firmware version to more reliable way is to enter the code ##86569726## (If supported by your version, which opens the menu whitelist/blacklist.
If the codes fail, as is possible on newer versions of Android 10/11 due to Google’s enhanced security policy, use an alternative route. Go to Settings -> Apps -> All Apps -> Phone (or Security) -> Notifications. You can indirectly manage the behavior of blocked calls, although you can not see the list itself.
Why can codes not work?
There is also the option of using ADB commands to view the list, but that requires a computer connection and having USB debugging.For the average Redmi 9 user, this method is redundant, but it guarantees access to hidden databases if the interface is corrupted.
Analysis of the blocked call log
It is important to distinguish between the Blacklist itself (where the numbers are entered for blocking) and the Lock Log (the history of attempts to call from these numbers). On Xiaomi Redmi 9, these functions are separated, but closely related. In the log, you can see who tried to reach you even if the call was silently rejected.
To view the log, go to the Security -> Antispam app. At the bottom of the screen or in the menu (three dots) is often the Records or History tab, which displays the date, time and phone number from which the blocked call or SMS came.
From this log, you can quickly add a number to a permanent blacklist, and just click on the entry, and in the context menu that appears, select the option "Add to a blacklist." This is convenient when the spammer changes numbers, and you want to block a specific incident.
| Function | Where to find out. | What do you need? |
|---|---|---|
| Blacklist | Call settings / Security | Storage of auto-dumping numbers |
| Lock log | Antispam -> History | Viewing attempted calls |
| Rules | Antispam settings | Automatic filtration by number type |
| Whitelist | Locking settings | Allowing calls to select only |
Regular log checks help identify new patterns of bypassing locks, and if you see multiple missed ones from different numbers in the same region, it makes sense to include the lock by mask or city code.
Third-party applications and synchronization
MIUI is usually sufficient, but sometimes more powerful functionality is required. Applications like Truecaller, Getcontact or Yandex.With a number detector can take on the function of a blocker, in which case the list of blocked numbers will be already inside these applications, and not in the system call.
If you installed this software, the system will suggest making it the default call app_blocked_The numbers will change, you will need to open the settings inside the application itself, the blocker. Often such programs have their own cloud databases, which are updated faster than the built-in lists Xiaomi.
However, using third-party identifiers requires extensive permissions, including access to contacts and wiretapping calls. By transferring data to third-party cloud services, you potentially risk the privacy of your phone book. The built-in Redmi 9 blocker is safer because it works locally.
⚠️ Warning: When installing third-party number detectors, disable the built-in lock MIUI, Two active blockers can cause the phone to stop responding to incoming calls or to reset all calls.
For most Redmi 9 users, the best solution is a hybrid approach: using a built-in hard filter for known spammers and installing a light number detector to identify unknown subscribers without fully handing over call management.
