How to Turn Off Unsolicited Calls on Xiaomi: The Complete Guide

Constant calls from intrusive advertisers, scammers, or simply unknown subscribers can drive even the most relaxed smartphone owner mad. Owners of Xiaomi, Redmi, and Poco devices face this problem regularly, because the MIUI or HyperOS firmware has powerful built-in protection tools that many are unaware of, ignoring these features leads to loss of time and nerves, and in some cases, financial losses.

Fortunately, you don't have to install third-party apps that often collect user data themselves. System filtering mechanisms run at the core of the Android operating system and are integrated into a standard phone, which allows you to effectively block spam without installing additional software, keeping the gadget running faster.

In this article, we will take a look at all the ways you can fight phone terrorism, learn how to set up a blacklist, activate Google filters, and create automatic rules for incoming calls, and fine-tuning these settings will make your phone an impregnable fortress for unwanted contacts.

Use of the built-in blacklist in the Phone app

The most basic but effective method is to blacklist specific numbers, which is very convenient and doesn't require deep immersion in the system settings in the MIUI shell, so to get started, open the standard Phone app and find a three-dot or gear button in the corner of the screen.

In the menu that opens, select "Block" and then go to "Blacklist." Here you will see two options: manually entering a number or selecting from a call history. If you've just been disturbed, the easiest way to click on the appropriate button and add a subscriber right away.

Xiaomi’s customization feature is the flexibility to manage notifications, so you can choose whether a caller will hear the beeps or receive a reset immediately, and it allows you to adjust the response to messages from blocked contacts by sending them to a separate folder without sound.

• 📞 Open the Security app and find the Blocking section".
• 📞 Click on the settings gear in the upper right corner of the lock menu.
• 📞 Select "Black List" and add the number you want manually.
• 📞 Activate the "Block incoming" switch for the selected contact.

It's important to understand that manual methods are good for specific offenders, but they're powerless against streaming spam from changing numbers. Mass protection requires more advanced tools, which we'll discuss later. Automation is the key to a quiet life.

💡

Periodically check the Locked folder to make sure that important calls from couriers or doctors are not getting there by mistake.

Activate spam filtering through Google Assistant

One of the smartest solutions for smartphone owners with pure Android or MIUI shells is the Call Filter, which is powered by artificial intelligence and allows you to detect spam before the phone starts ringing, a smart lock that analyzes a database of known scammers.

To activate this feature, you need to go to the settings of the application "Phone" from Google. If you have a standard dialer from Xiaomi, it is recommended to switch to Google Phone through the Play Market, since its filtering algorithms are considered one of the best in the industry. After installation, open the settings and find the section "Number and spam".

Here you'll be offered several layers of protection, you can turn on just the number definition, or you can activate full filtering, where the phone won't even vibrate when you call from a spam-labeled subscriber, and this allows you to completely ignore unwanted calls.

⚠️ Attention: Spam database filtering requires an active Internet connection. Without a network, unknown number detection will not work.

Google also offers Caller Verification, which, when you get a call, can automatically answer the call and ask who's calling and what's the question, and you'll see the transcription of the conversation on the screen and decide whether to pick up, which is ideal for dealing with answering robots.

Configure modes "Do not disturb" and hide numbers

If spam attacks with incredible force and no filters help, you can use a radical but effective method: Do Not Disturb. Unlike conventional lockdown, this mode allows you to create a whitelist, skipping calls only from selected contacts from your phone book.

To set this up, go to Settings → Sound and Vibration → Do Not Disturb. Under People or Calls, select Contacts Only or Favorites, in which case any numbers that are not on your contact list will automatically be rejected by the system without your involvement.

This method is especially relevant on weekends or during important meetings, when no interruptions are allowed, but it is worth remembering that couriers, taxis and delivery staff often call from unknown numbers, so be careful when choosing such a rigid filtration mode.

• 🔇 Go to the sound settings and select Do not disturb mode".
• 🔇 Click on "People" or "Allow calls from".
• 🔇 Set the "Contacts Only" value for maximum silence.
• 🔇 Set up a schedule so that the mode is turned on automatically at night.

Also available in modern versions of MIUI is the ability to hide the number when an incoming call is identified as potentially dangerous, the screen can simply not light up, and the call immediately goes to the missed log, which reduces stress, since you do not see a constantly pop-up with an annoying number.

Comparison of blocking methods: efficiency table

The best defenses depend on your specific needs and the type of calls you are concerned about. Some are better suited to combat robots, others are better suited to intrusive collectors. Below is a comparative description of the main methods available on Xiaomi devices.

As you can see from the table, manual blacklisting is not effective against mass calls, as scammers constantly change numbers. The most balanced solution is to use Google's built-in algorithms in conjunction with manual adjustments, which provides a high level of protection without the risk of isolation from the outside world.

Using third-party identifiers like GetContact or NumBuster is also popular, but carries privacy risks.These apps often upload your phone book to their servers, which can violate the privacy of your contacts. Embedded tools Xiaomi and Google in this regard are safer.

Blocking Hidden Numbers and International Calls

A separate category is called from hidden numbers ("Unknown") and from abroad, and at the carrier level or in the engineering menu of a smartphone, you can set a ban on receiving such calls, which is especially true if you receive threats or intimidation.

To block hidden numbers, a service is often required from the operator (for example, "Anti-determiner" on the contrary), but in some cases, setting up through the Internet helps. USSD-For example, the *31# code usually controls the number definition, but to block incoming hidden subscribers, it is better to contact your operator’s support team or use the Xiaomi Security app.

In the Security app -> Antispam -> Settings -> Locking, you can find the option "Block Hidden Numbers." Activating this switch will instantly cut off anyone who tries to hide their ID. Be careful: some organizations (banks, clinics) may call from hidden numbers.

⚠️ Attention: International number locking can be useful if you don't wait for calls from abroad, and it will save you from the popular type of scam "Honk" when you get a call from a number of another country and reset.

If you travel frequently or have relatives abroad, create an exception for specific country codes in the lock settings, which will allow you to combine protection against fraud and the ability to communicate with loved ones. MIUI This allows you to finely adjust these parameters.

Third-party applications: is the risk worth it?

Google Play has a lot of apps to block calls, which promise millions of databases and instant detection, but installing them on Xiaomi often leads to conflicts with the system phone app, causing dialing delays or missing call history.

In addition, many of these apps are overloaded with ads and require excessive permissions, and they can request access to SMS, contacts and location, which creates a security breach, and the built-in MIUI functionality, based on the Avast antivirus engine or Google databases, often does just as well.

If you do decide to use third-party software, choose proven open source solutions or from well-known security vendors. Be sure to set exceptions so that the application does not block important service numbers of banks or emergency services. Remember that one extra application is an additional consumption of battery and RAM.

• 🛡️ Avoid apps with low ratings and low downloads.
• 🛡️ Check the permission list before installing any program.
• 🛡️ Give preference to system solutions Xiaomi and Google.
• 🛡️ Regularly update the spam number databases in the selected application.

In most cases, setting up the standard Dialer interface and activating Google’s protection completely solves the problem of spam.

💡

The built-in tools of MIUI and Google provide 95% of the necessary protection without installing additional applications and the risk of data leakage.
