How to remove antispam on Xiaomi phone: the complete guide

Owners of Xiaomi, Redmi and POCO smartphones often encounter an intrusive "antispam" feature that can block important calls or interfere with the operation of the number detector. The standard MIUI shell and the new HyperOS have powerful security tools, but sometimes their algorithms work too aggressively. Users complain that the system mistakenly flags contacts from the delivery list or courier services as spam, making it impossible to take a call.

Fortunately, it can be completely deactivated or fine-tuned to your needs. In this article, we’ll look at all the ways to turn off filtering, from basic call settings to advanced methods through the engineering menu. Lock management is a key skill for comfortable smartphone use, which will allow you to not miss any meaningful calls.

It is important to understand that not only the built-in Security app but also Google system services are responsible for removing unwanted calls, so you will need to check the settings in several sections to get the full result, and we will look at each step in detail so that you can choose the most appropriate solution to the problem.

Disabling anti-spam via the Security app

The main filter control tool is in the system application Security, and this is where the main switches that are responsible for blocking incoming calls and the main switches are located. SMS-First, look for a shield and lightning icon on your desktop, launch the app.

In the interface, look for the Antispam or Lock section. Depending on the version of the MIUI shell or HyperOS, the name may vary slightly, but the icon usually remains the same. Clicking on this item will take you to the lock list management menu.

• 📱 Click on the gear in the upper right corner to access settings.
• 🚫 Select the “Black List” option to view blocked numbers.
• 🔔 Go to the “Blocking Rules” section to control automation.
• 📞 Disable the "Block by tag" switch to remove restrictions.

In the Lockdown Rules menu that opens, you'll see a list of categories that the system considers suspicious, such as Advertising, Fraud, Telemarketing, and others, and if you want to remove antispam completely, you need to put all the switches inactive.

⚠️ Warning: After all filters are turned off, your phone will become vulnerable to real spam and advertising calls.

You can also set up "Block Notices" here, so if you want to know who the system has tried to block, leave this option on, so you can monitor the effectiveness of the filter even if it's partially disabled.

Set up the built-in Google number definition

Many users forget that on modern Xiaomi smartphones, Google Assistant and built-in determinant work in parallel with the proprietary system, which often marks calls in red or automatically resets them, considering them spam.

To access these settings, open the standard Phone (green handset) app. In the upper right corner, click on three vertical dots and select Settings. Next, look for the Antispam or Spam filter section.

Here you'll see the Spam Filter switch, and if it's active, it'll use Google's database to check incoming numbers, and you can turn it off completely or leave it, but remove the hidden number lock.

Interestingly, Google allows you to create your own rules, for example, you can only ban calls from hidden numbers or from first-time callers, which is a more flexible approach than blocking them completely.

• 🌐 Google's global database of spam numbers is used.
• 🔍 It works even without installing additional applications.
• 📉 Reduces the load on the processor compared to third-party solutions.
• ⚙️ Integrated directly into the call interface.

If you prefer third-party solutions, such as Yandex or GetContact, then the built-in Google filter is better to turn off to avoid conflicts.

Control locking through system call settings

The in-depth telephony settings are hidden in the general settings menu, which is suitable if the Security app label has been removed or changed, and you can find additional controls for incoming calls here.

Go to Settings, then select Apps. Search All Apps and find the Phone system app (usually with a Google or MIUI logo). Click on it and select Permissions.

It is important to check what access rights the app-definitions have. If you want to remove anti-spam, make sure that the unneeded identifiers (for example, preinstalled Mi Notepad or old versions of Clean Master) do not have access to the phone and contacts.

Also, the phone app itself can have a "Block Unknowns" option, so make sure it's turned off if you want to take calls from any number, even those that aren't in your notebook.

Using an engineering menu to reset settings

For advanced users, there is a way to reset network settings and telephony via an engineering menu, which can help if anti-spam is stuck at the software level and conventional methods don’t work.

Open the Phone app and dial the combination ##3646633##. If the code doesn't work, try ##4636##. You'll see a hidden menu from a MediaTek or Qualcomm engineer.

Menu path: Telephony → SIM1 (or SIM2) → Call Settings → Call Barring

You can check the status of the various restrictions here, but be very careful: changing unknown parameters can lead to loss of communication, changing the settings in the engineering menu can lead to loss of warranty for the software.

Most often, the problem is solved by resetting network settings, and in the same menu 4636 you can find the item “Reset network settings” (if available with your model), which will return all call parameters to factory values by removing user filtering rules.

Removing Third-Party Blocker Applications

Often, third-party applications that the user has installed before are the source of problems. Antiviruses, memory “optimizers” or special number detectors can conflict with Xiaomi’s system.

Check the list of installed applications for programs like Avast, Kaspersky, Clean Master, Hiya or Truecaller. If you are not actively using them, you should remove them.

• 🗑️ Remove the application through the menu "Settings» → «Annexes».
• 🚫 Revoke device administrator rights before deleting.
• 🧹 Clean the cache after removing junk files.
• 🔄 Reboot your smartphone to apply changes.

Pay special attention to apps that have permission to "Map on Other Windows" and "Access to Call Log," which intercept an incoming call before the system and decide whether to skip it or not.

⚠️ Note: Some Xiaomi system applications (such as Mi Credit or Mi Pay in certain regions) may contain security modules.

If you can't remove the app in the standard way, use Safe Start mode. Press the Turn Off button, and when the Turn Off icon appears on the screen, press and hold it with your finger for a few seconds, and the system will suggest that you go to Safe Mode.

Solving problems with the operator's determinant

Remember, antispam can work on the side of your cell phone provider, and services like MTS’s Antispam, Beeline, Megaphone, or Tele2 block calls before they even reach your phone.

The status of the service can be checked through the operator’s personal application or USSD-These services are often automatically or as part of packages, and if you don't want to use them, turn them off via the SIM card menu.

For example, the following commands are often used to turn off (may vary depending on the region):

• 📞 MTS: *152*2# or through the application "My MTS».
• 📞 Beeline: *110*7722# or in a private office.
• 📞 Megaphone: *555*52# or.

Also check the forwarding settings. If you want to redirect to a listening service or a secretary, it can look like a lockdown. You can reset all forwardings with the ##002# command.
