Xiaomi smartphone owners often face the need to filter incoming calls, and the number detector becomes not just a convenient feature, but a vital tool for protecting against fraud and intrusive advertising. The Android ecosystem, which runs the MIUI shell, has several caller identification mechanisms, each with its own specifics of operation and database.
Activating this option can dramatically change your phone experience, no longer having to guess who is calling from an unfamiliar code or answering offers of “best-for-profit” credits. Modern algorithms allow you to automatically block spam before the first buzzer sounds, using cloud databases updated by millions of users.
In this guide, we will look at all the ways you can customize your subscriber identity, look at both the built-in features and popular third-party solutions that perfectly integrate into your gadget’s interface, and understand these settings will allow you to create a personalized screen against information noise.
Use of the built-in capabilities of Google Assistant
The most reliable and secure way to identify callers is to use native services from Google. Most modern Xiaomi models, especially those that have entered the global market, pre-installed the Google Phone app, which has a powerful built-in Caller ID engine that works without installing additional software.
To activate the function, you have to open the application and go to settings, usually three dots in the corner of the screen or gear, find the section "Antispam and Identification", and this is where the key switches that display the names of organizations and alerts for potentially dangerous calls are hidden.
It uses a huge Google database that is constantly updated, and if a number is tagged as spam by other users, you'll see a red alert on the lock screen, which allows you to make an informed decision whether to respond, reset or ignore a call.
⚠️ Note: Google Assistant requires a stable Internet connection at the time of incoming call, as the number is checked in real time through the cloud.
It is important to note that Google’s algorithms are updated frequently, and check periodically for updates for the Phone app itself in the Play Market store to get the latest spammer databases.
Yandex.Phone Service for CIS Regions
For users from Russia and CIS countries, Yandex.Phone is a great solution, replacing the standard caller and offering one of the most relevant databases of numbers in the region, and installing this application is the first step to a comfortable life without spam.
Once installed and given all the necessary permissions, the service automatically integrates into the system, it can identify the numbers of even those organizations that are not already listed in directories, but often call users, machine learning algorithms analyze the behavior of the caller and flag suspicious activity.
You can configure filters in the application settings, you can only allow calls from the contact book or enable an "Anti-Detection" that hides your number when outgoing calls (paid option). The interface of the program is minimal and fully adapted to the MIUI style.
One of the key features is that you can listen to music instead of beeps while the person is waiting for the connection, which makes the waiting process more enjoyable, and the app automatically records conversations if you turn this feature on the settings menu.
💡
For the best work of the Yandex.Phone determinant, add the "Search for Number" widget to the desktop - this will allow you to punch through unknown numbers manually, simply by typing them into the search bar.
Integration of third-party applications: GetContact and Truecaller
When built-in tools are scarce, specialized identifiers come to the rescue, with Truecaller and GetContact leading the market, and with huge databases built by users around the world.
The principle behind this is cross-platform contact synchronization, so when you install an app like this, it (with your permission) uploads hashed numbers from your phone book to a shared database, so you can see how other people's numbers are recorded.
But privacy is important, because using these services, you actually share your contacts with the developers' servers, and in Android privacy settings, you can restrict the app to the call log without handing over the entire phone book, although the functionality can be stripped.
These apps often have paid subscriptions that offer advanced features, such as hiding ads or seeing other people’s search history for your number, and the free version is enough to base your incoming calls on.
Comparison of methods of identification of subscribers
To choose the best solution, it is important to understand the differences between the methods available, each with its own strengths and limitations, depending on your needs and smartphone usage habits.
Below is a comparison table of the main characteristics of popular solutions for Xiaomi, which will help you quickly navigate the functionality and choose the right option.
| Characteristics | Google Phone | Yandex.Phone. | GetContact |
|---|---|---|---|
| Database | Global (Google) | Regional (CIS) | User-generated (Tags) |
| Working without the Internet | Partially. | Network required | Network required |
| Impact on the battery | Minimum | Average. | High. |
| Cost | Free of charge. | Free (there's Plus) | Freemium |
As the table shows, for users in Russia and neighboring countries, Yandex is often the most effective solution thanks to its localized database.
Apps like GetContact are better used as a tag checker, rather than as a primary call, because of the higher system resource consumption.
Filtering and blocking in MIUI
Xiaomi’s MIUI shell has its own powerful security module, which doesn’t identify cloud callers as well as Google or Yandex, but it’s great at blocking numbers by mask or list.
To access these settings, open the Security app (green zipper icon) and go to Antispam, where you will find blacklist and hidden number lock settings, which is critical for combating robot callers.
You can set up a lock by keywords in SMS or by number prefixes, for example, if you get frequent calls from numbers that start with a specific code, you can create a rule to automatically reject them.
⚠️ Be careful when enabling the “Block All Hidden Numbers” feature, as you may receive calls from bank or emergency personnel whose numbers may also be hidden by the operator’s system.
Remember to regularly update the spam databases within the Security app. Xiaomi periodically releases updates to these lists to counter new scammer schemes.
Solving the problem with the determinant on Xiaomi
Sometimes users are faced with a situation where the determinant stops working, the number is displayed simply as numbers, without a name, most often the problem lies in the permissions of applications or the power saving settings.
HyperOS and older versions of MIUI aggressively save battery power by unloading background processes. If the detector application "drops" it can't handle the incoming call, you need to go to the battery settings and select "No Limits" mode for your number detector.
Also check for conflicting applications. If you have two determinants (like Google and Yandex), they may be in conflict over the right to handle incoming calls. Leave only one active application for default calls.
In some cases, resetting network settings or reinstalling Google Play Services updates helps. Make sure the date and time on the device are set correctly, as sync errors can disrupt security certificates.
