How to get rid of spam calls on Xiaomi phones forever: from built-in tools to secret MIUI settings

Spam calls have become a modern scourge: scammers, intrusive marketers and robot phone users are poisoning the lives of smartphone owners. Xiaomi users are especially vulnerable, because the popularity of the brand makes them a tasty target for spammers. According to Truecaller statistics for 2026, every second subscriber in Russia receives at least 3 spam calls per week, and in some regions this figure reaches 10-15 calls. But the good news is that MIUI offers one of the most advanced tools for combating spam among all Android shells.

In this article, we will analyze all available methods of blocking – from the basic settings of the built-in application “Phone” to hidden functions. MIUI 14/15 You'll learn how to weed out not only obvious scammers, but also "grey" calls with swapped numbers (spoofing), and set up protections so that you don't miss important calls. Particular attention will be paid to the unique function “Keyword Blacklist”, which is not in standard Android, but which is in Xiaomi firmware since the Redmi Note. 10.

1. Built-in tools MIUI: Basic protection against spam

MIUI firmware (up to date 14/15) includes a powerful arsenal for filtering unwanted calls out of the box, and the main advantage is that these tools do not require the installation of additional applications and work at the system level, saving battery life.

Open the standard Phone app (tube icon) and go to Spam (three dots in the upper right corner → Settings → Spam and lock).

• 🔍 Spam Identification: The system automatically flags suspicious numbers based on Xiaomi’s database and user reviews. Turn on the slider to see warnings about possible spam during an incoming call.
• 🚫 Spam Blocking: Activates automatic call drops from numbers labeled as fraudulent, even if the phone is in Do Not Disturb mode".
• 📱 Cloud spam database: syncs spam data between Xiaomi devices in real time. Useful if you have multiple brand gadgets.

Note the Blacklist section in the same menu, where you can manually add numbers or whole ranges (e.g., all numbers with the prefix +7900). To block the bulk, use the import function from the.txt or.csv file, which is convenient if you have a list of spammers from the carrier.

💡

If your spam filter settings are missing after the MIUI update, reset the Phone app cache to Settings → Apps → App Management → Phone → Storage → Clear the cache. This will return hidden options without losing data.

2. Advanced customization: filtering by keywords and regions

Xiaomi offers a unique feature that is not in pure Android – blocking calls by keywords in the subscriber’s name. This option saves from spammers who constantly change numbers, but use the same templates in the caller ID (for example, “SberBank”, “Gift from MegaFon”, “Your parcel”).

To adjust the filter:

1. Go to Phone → Settings → Spam and Lock → Identity settings.
2. Select the keywords to block.
3. Add comma phrases (registrar is not important) Examples: credit, winning, gift, bank, tax.
4. Activate the option to block calls with these words.

Another powerful tool is geographic filtering, so if you don't expect international calls, lock all the numbers from abroad:

1. In the same menu, select International Numbers.
2. Set the switch in the Lock position.
3. Exceptions include the countries from which you want to receive calls (for example, Belarus or Kazakhstan).

3. Secret MIUI features: how to block "invisible" spam

Few people know, but MIUI has hidden settings that allow you to block spam at the system level, bypassing the standard Phone app. These features are especially useful if you use third-party calls like Google Phone or Truecaller, but want to keep protection from Xiaomi.

The first way is to activate the system spam filter through the engineering menu:

##4636## → Phone Information → Menu (three dots) → Additional settings → Spam filter

You can manually add numbers that are not blocked by standard methods, for example, some scammers use numbers with non-standard prefixes (+7800) that do not fall under the usual rules.

The second secret method is to set up locking rules through ADB (for advanced users), which allows you to create custom filters, for example, block all calls from numbers containing repeating numbers (+79991231231).

1. Connect your phone to your PC and activate USB Debugging in Settings → About Phone → MIUI version (shap 7 times).
2. Enter the command: adb shell settings put global spam_filter_custom_rules "+7900*,+7902*,*12345#" (replace the templates with your own).
3. Reset the device.

4. Third-party applications: when embedded tools are not enough

If spammers are too many or use complex bypass schemes (for example, they call from new numbers every time), it is worth considering specialized applications. The main advantage of third-party solutions is that they update the databases of spam numbers in real time, while the built-in Xiaomi database can lag by 1-2 weeks.

Top.-3 applications for Xiaomi 2026 year:

• 🛡️ Truecaller: the largest spam number database (over 500 million records) Free version shows who is calling, but lock is only available in Pro (~300 rubles/month Integrated with MIUI system-bell.
• 🔒 GetContact: specializes in Russian and CIS spam, can recognize gray numbers that have not yet been blacklisted, and minus requires access to contacts.
• 📞 Who called?: domestic solution with support for blocking by category (credits, fraudsters, advertising). There is a function "Quiet mode" - spam calls are reset without sound.

Important: When installing third-party calls, turn off the built-in spam identification in MIUI to avoid conflicts. Go to Phone → Settings → Spam and Blocking and deactivate the Spam Identification option.

Install an app from Google Play|Register (required!)|Turn on Truecaller as a default caller|Import the blacklist from MIUI|Set up automatic lock in the Premium version-->

For maximum protection, combine Truecaller (for international spam) and GetContact (for local scammers). Remember to manually update your databases once a week, which increases your chances of catching new spammers.

5. Operator services: blocking at the level SIM-map

All major Russian carriers offer spam filtering services that work independently of the phone model, blocking calls before they reach your Xiaomi, reducing battery load, with the main drawbacks being paid rates and not always up-to-date bases.

Comparison of services from operators (2026):

To connect the service:

1. Send. USSD-team: MTS: *111*789# Beeline: *110*789# Megaphone: *105*456# Television2: *225*1#

Or activate in the personal account on the operator's website.

Reboot your phone to make the changes take effect.

💡

Operator filters work even if the phone is turned off or on an airplane, and this is the only way to block spam at the network level, but they are useless against international fraudsters with swapped numbers.

6.Extreme measures: how to block all unknown calls

If you're so annoyed that you're willing to sacrifice incoming calls from strangers, MIUI has a total lock function, which is a radical method, but it's guaranteed to get rid of spam. Use it if:

• 📵 You get more than 10 spam calls a day.
• 🕵️ Fraudsters use a swapping of your number (spoofing).
• 🔇 You don’t care about calls from unknown numbers (for example, you only expect calls from contacts).

Instructions for setting:

1. Open the phone → Settings → Lock numbers.
2. Activate the option to block unknown numbers.
3. Enable Hidden Numbers Block (for calls with caller ID disabled).
4. Add important numbers (such as shipping services or banks) to the exceptions through the Permitted Numbers.

💡

If after activation of total blocking SMS from banks or services stopped coming, add their short numbers (for example, 900 for Sberbank) to the section Allowed numbers in the message settings.

For even more severe filtering, use a combination of:

Settings → Applications → Permissions → Phone → Additional → Blocking Calls → Blocking All Calls Except Contacts

In this case, only those who are saved in the phone book will be able to call you, and the disadvantage is that you risk missing important calls (for example, from a doctor or a new employer).

7.Additional measures: how to reduce the amount of spam in principle

Blocking is a response to a problem, but you can proactively reduce spam calls by following a few rules:

• 📱 Don't publish a number in the public domain: remove it from social networks, forums and marketplaces. Use messengers to communicate.
• 🛒 Give up. SMS-mailing: when buying in online stores, uncheck the tick "I agree to the newsletter".
• 🏦 Check the settings of bank cards: in mobile banks (Sberbank Online, Tinkoff) disable the option "Allow partners to call about shares".
• 🔄 Change the number once 2-3 If spam is unbearable, it is easier to change SIM-map, how to deal with the consequences of data leakage.

Another effective method is to register with the Do Not Call Registry, which in Russia is run through Roskomnadzor to add a number:

1. Go to the website pd.rkn.gov.ru.
2. Fill out the form with passport details and phone number.
3. Confirm registration via SMS.
4. After 30 days, your number will be removed from the databases of legal call centers (but not scammers!).

Unfortunately, this method does not protect against illegal spam, but reduces the number of calls from official companies by 40-60%.
