How to completely remove antispam on Xiaomi: 5 working ways

The spam filter on Xiaomi smartphones often blocks not only advertising messages, but also important notifications from banks, delivery services or even personal correspondence. MIUI users regularly face a situation where SMS from the payment confirmation or the code from the messenger gets into the Spam folder, and incoming calls from unknown numbers are automatically reset. In this article, we will analyze all ways to disable anti-spam from basic settings to hidden developer parameters.

It’s important to understand that Xiaomi’s filtering system works on multiple levels, from embedded MIUI software to Google services (for Google Mobile Services devices), to even carrier services. We’ll focus on settings that can be changed without superuser rights. If you’re using custom firmware or a modified version of MIUI, some menu items may be different — let’s warn you about this separately.

1. disabling anti-spam in the standard application "Messages"

The most obvious way is to deactivate the filter directly in the default messenger, which works on all Xiaomi devices with MIUI 12 and later, including the Redmi Note 12, POCO X5 and Xiaomi 13. Importantly, after disabling all previously blocked messages will remain in the Spam folder, but new ones will no longer get there.

Instructions:

• 📱 Open the Messages app (Icon with envelope).
• ⚙️ Click on three dots in the upper right corner → Choose "Settings".
• 🛡️ Go to the Spam filter section (or Blocking and Spam in some versions).
• 🔄 Turn off the spam filter slider (should turn gray).
• 🗑️ Clear the Spam folder if you want to delete previously blocked messages.

Some firmware (e.g. MIUI 14 for the global version) may require additional confirmation via CAPTCHA. If the filter continues to work after the shutdown, check your sync settings with your Mi Account - sometimes the spam filter settings are reset when you update the system.

2.Change the call filter: how to disable number lock

MIUI automatically blocks incoming calls from numbers labeled “fraudulent” or “spam” in Xiaomi’s database, which causes calls from couriers, taxis, or even bank call centers to be dropped without notice.

Steps to shut down:

1. Go to the phone app (green handset).
2. Click on three points → “Settings” → “Number locking”.
3. Turn off the options: 📞 "Blocking Unknown Numbers" 🚫 "Block numbers from the blacklist" 🔍 "Identification of spam calls (in some regions)

“Special capabilities”

"Call management"

If the calls still don't go away after the shutdown, the problem may be on the operator's side, for example, MegaFon and Beeline offer their own spam protection services that work regardless of the smartphone settings. USSD-team or personal account of the operator.

3. Hidden settings: disable antispam via "Security"

The Security app (or "Security" in the Russian version) contains additional filtering options that are not visible in the standard settings. Here you can disable not only the spam filter for SMS, but also the blocking of notifications from applications. This method is relevant for devices with MIUI 13/14, where some functions are transferred from the main settings in the Security App.

Step-by-step:

• 🔒 Open the Security app (Icon with shield).
• 📊 Go to the "Management" tab (or "Tools").
• 🔍 Find the "Spam" or "Spam Protection" section".
• 🔄 Turn off all sliders associated with: 📧 Message filtering 📞 Blocking calls 🔔 Notifications from annexes
• 🔧 In some versions MIUI You can also reset the database of spam numbers (option "Clear the log").

If your MIUI version does not have a Spam section in the Security app, then the filtering is controlled exclusively through standard Messages and Phone, which is typical for the firmware market in Europe (EEA).

4. ADB-commands to completely disable antispam (for experienced ones)

If standard methods don't work, you can use Android Debug Bridge (ADB), a low-level system management tool that is suitable for users who are willing to work with the command line, an advantage of which is that it disables the system-level spam filter, including hidden Xiaomi services.

Step-by-step:

1. 🖥️ Install. ADB Download from the official Android Developers website).
2. 📱 On your smartphone, activate Developer Mode: Go to Settings → About the phone. Press 7 times on "Version." MIUI". Go back to "Settings" → "Additionally" → "For developers. Turn on "Debugging by" USB".

adb shell pm disable-user --user 0 com.miui.antispam


adb shell pm disable-user --user 0 com.miui.securitycenter

These commands disable the system applications responsible for filtering spam.

🔄 Reset the device.

⚠️

Note: Disabling system applications via ADB may cause some features (such as security notifications or updates) to work unstable.To get everything back, use the command: adb shell pm enable com.miui.antispam

5. Problems after disabling anti-spam and their solutions

After deactivating the spam filter, users often experience side effects, and here are the most common problems and ways to fix them:

If you start receiving too many unwanted messages after turning off anti-spam, consider alternative solutions:

• 📲 Install a third-party messenger (like Google Messages) with your own spam filter.
• 🛡️ Use apps like Truecaller to manually lock numbers.
• 📵 Set up a “blacklist” manually for the most intrusive senders.

💡

To quickly add a number to the blacklist right during the call, click on the red handset in the incoming call interface and select "Add to the blacklist".

6. Features for different Xiaomi models

Anti-spam functions may vary depending on the device model and regional firmware, and the following are key nuances for popular lines:

Smartphones of the Redmi Note series (11/12/13):

• 🔹 V MIUI 13 for Redmi Note 11, anti-spam is managed only through Messages and Phone".

Xiaomi 12/13/14 flagships:

• 🔹 Support dual filtration: separate for SIM1 and SIM2.

POCO devices (F4/F5/X5):

• 🔹 Nana POCO Global firmware antispam is often disabled by default.
• 🔹 V POCO X5 Pro spam filter integrated into Game Turbo (unexpectedly, but a fact).

For devices with MIUI for Russia (e.g. Redmi 10C or Xiaomi 11 Lite NE), you may need to change region to India or Global via Settings → Additional → Region to unlock all anti-spam options.

💡

On firmware devices MIUI China (for example, those brought from China) only disables anti-spam via the ADB or after the installation of a global/EEA-firmware.

7. Alternative methods: how to bypass antispam without turning off

If you do not want to deactivate the filter completely, but need to receive specific messages (for example, from a bank or delivery service), use these methods:

Adding numbers to the white list:

1. Open "Messages" → "spamming".
2. Press three points. → "Whitelist".
3. Add numbers or keywords (e.g. Sberbank, Ozon).

Use of short numbers:

• 📱 Banking and service SMS They often come from short numbers (for example, 900 for Sberbank).
• 🔢 Add them to contacts with the name "Sberbank Notifications" - this will increase the chances of delivery.

Redirecting SMS to email:

• ☁️ Set up sending important messages to the mail via Settings → Google → Backup → SMS-message.
• 📧 Use services like this. IFTTT automatic SMS.

If you need to temporarily turn off anti-spam (for example, while waiting for an important message), just switch the phone to Flight Mode for 10 seconds, and then return to normal mode, which resets some background processes, including filtering.
