Owners of Xiaomi, Redmi and Poco smartphones often face intrusive calls from scammers and advertising agencies. Built-in protections work well, but are not always able to recognize current number databases that are constantly updated. Yandex Determinator offers one of the most powerful solutions on the market, effectively weeding out unwanted calls even before they make your pocket vibrate.
But the process of integrating it into the MIUI or HyperOS shell has its own technical nuances that require user attention. The standard procedure for installing an app from the Google Play or Yandex Store is just the first step, followed by a series of mandatory permission settings. Without the right configuration, Android can force the background processes to shut down, reducing the security effectiveness to zero.
In this article, we will take a look at each stage of the setup so you can be sure of the reliability of your phone. We will look not only at the basic activation, but also at the subtleties of working with system restrictions that are characteristic of the Chinese manufacturer's devices.
Pre-preparation and installation of components
Before you start deep customization, you need to make sure that your device has all the required software modules. Yandex Determiner on Xiaomi devices often requires an additional plugin to integrate with the system “caller.” This is due to the fact that Android strictly regulates the access of third-party applications to manage incoming calls.
Download the main Yandex with Alice app or a separate Yandex Determiner app from the official store. In most cases, you also need to install Yandex Determiner: Call Plugin to work fully on Android. This module takes over the function of intercepting and analyzing the number when a call arrives.
⚠️ Note: If you are using a global version of the firmware MIUI Global, make sure that the region settings have "Russia" or "Ukraine" installed. In some cases, in the "US" or "India" region, the number determination functions may not work correctly or be available.
After installing the main application and plugin, take your time to immediately open the settings. The system should index new services. Rebooting the device at this stage will be a great solution to ensure that all Yandex background services start correctly and register with the system. This is especially important for older models of smartphones with a small amount of RAM.
Make sure you have an active Yandex ID account, too. The service requires authorization, as the number database and personal settings are stored in the cloud. Without logging in, the functionality will be severely limited, and you will not be able to manage the blacklist remotely.
☑️ Preparation for installation
Basic activation and login
Run the Yandex Definition app or open the settings through the Yandex app. The first screen you see is a prompt to turn on protection. Press the appropriate button, after which the system will request permission to use the number determination service. This is critically important, because without this permission, the phone will not be able to show the name of the caller on the lock screen.
The algorithm of the service involves checking the incoming number with the contact database and the cloud base of Yandex, the permission is necessary so that you see not only unknown numbers, but also the names of those who are recorded in your phone book, if they are displayed differently in the interface of the call.
The activation process may require confirmation via SMS. This is the standard verification procedure to ensure that the phone number truly belongs to you.The cost of the message corresponds to your carrier's rates, but usually it is one free or minimum cost message.
- 📱 Click the “Enable Determiner” button on the main screen of the application.
- 🔐 Allow access to contacts and phone book in the system window that appears.
- 📲 Confirm possession of the number through the code from SMS or push notifications.
- ✅ Wait for the message of successful activation of the protection.
Once activated successfully, the app interface will change to show the status of "Protect is on." Now the service is ready to go, but on Xiaomi smartphones it is only half the way. The aggressive policy of energy saving the shell of MIUI can at any time "kill" the number determination process, if you do not configure exceptions.
💡
Use the same Yandex ID account across all your devices, allowing you to synchronize your blacklist and call history between your phone, tablet, and smart speaker.
Configure permissions in the MIUI and HyperOS system
MIUI shells and the new HyperOS are famous for their tight control over background processes to save battery power. To keep Yandex Determiner stable, you need to manually make changes to your application settings. Ignoring this step will cause the detector to stop working within a few hours after turning on the screen or going to sleep.
Go to Settings → Applications → All apps. Find Yandex Determiner and Yandex Determiner: Call Plugin (if installed separately). You will need to visit each of these points. First, find the AutoStart section and activate the slider. This will allow the service to run with the operating system after the phone is restarted.
Next, go to the charge saving section (or battery) inside the app settings, and the default is "Energy saving" mode, and you need to switch it to "No limits," a critical setting that prevents the system from forcibly stopping the detector processes even if the screen is off for a long time.
⚠️ Note: On some versions MIUI (Especially the Chinese versions. CN ROM) The system call can block third-party plugins, in which case the detector will only work when the screen is unlocked, which reduces its effectiveness.
Also, be sure to check permissions under Permissions. Make sure the app is allowed to "Display on top of other apps" and access to "Phone." Without the right to display on top of other windows, you won't see a pop-up with the caller's name if the caller isn't in your phone book.
What to do if the settings are reset?
Integration with system telephony and Google Dialer
Xiaomi smartphones in different regions can use different applications for calls: its own MIUI Dialer or the standard Google Phone. The process of integrating Yandex Determiner differs slightly depending on which “caller” is installed by default. In modern models, it is the solution from Google that is most often found.
If you have Google Dialer, open the Phone app, click on the three dots in the top right corner and select Settings. Find Caller ID & Spam. Select Yandex from the list of available services. If there is no such option, the plugin may be incorrect or the version of the app is outdated.
If you use MIUI Dialer (specifically for Chinese firmware or older models), the settings may be inside the Xiaomi Security app itself. Open Security → Antispam → Settings → Blacklist. Here you can choose the source of the databases to lock. However, for displaying names, you can rely on the settings of the Yandex application itself, which intercepts the call before the system unit.
| Type of caller | The path to settings | Required module | Stability of work |
|---|---|---|---|
| Google Phone | Phone → Settings → ID and spam | Call plugin | Tall. |
| MIUI Dialer | Security → Antispam | Main annex | Medium |
| Third-party (Truecaller et al.) | Application settings | Not required | Low. |
It is important to understand that the simultaneous activation of multiple number determinants (for example, Yandex and built-in Google Spam) can cause conflict. The phone may begin to vibrate twice or not show the name at all. It is recommended to keep only one main definition service active, preferably Yandex, since its databases for Russia and the CIS are most relevant.
Once you have set up the integration, make a test call from another number that is not in your contact book, and if the organization name or the "Spam" tag appears on the screen, then the integration was successful, and if the call went as usual, without a pop-up, go back to the permissions step.
Spam Management and Blacklisting
One of the main functions of the service is not just to identify, but also to actively combat unwanted calls. In the application Yandex Definition, there are flexible filtering settings. You can choose which categories of numbers to block automatically: for example, Advertising, Surveys or Fraudsters.
To access these settings, open the app and go to Settings or Filters, where you'll see switches for different categories. Activating Ads lock will allow the phone to not call at all when such calls arrive — the subscriber will hear the beeps, and you will not have anything on the screen, or the call will be immediately reset with a note in the log.
- 🚫 Blocking hidden numbers: an option to cut off calls from unknown ID. Be careful: couriers and delivery staff often call from hidden corporate phone numbers.
- 🏢 Blocking Organizations: The ability to blacklist a specific company even if they are calling from different numbers.
- 👤 Personal blacklist: manually adding specific numbers that bother you personally.
There's also an anti-spam feature available, which works in a similar way to calling, hiding advertising. SMS It helps keep the inbox clean and keep important bank confirmation codes out of the noise.
⚠️ Note: When you enable hard-lock hidden numbers, you may miss an important call from a doctor or emergency officer using a corporate PBX.
All blocked calls are stored in a log inside the app, so you can always look at the history of the person who tried to reach you, and if necessary, return the number to the whitelist, which gives you full control over incoming traffic and allows you to analyze the activity of spammers.
💡
Flexible filter settings allow you to fully automate spam protection, but require an initial manual calibration to suit your lifestyle.
Extended Features and Paid Subscription Plus
The basic version of Yandex Determinator is free and functional for most users, but there are additional features for Yandex Plus subscriptions or Yandex Plus tariff holders, and the main bonus is the ability to see numbers that other users have identified, even if they are not already listed in the general database as spam.
In addition, subscribers can access the Advanced Definition, which shows not just their name, but additional data: the address of the organization, mode of operation, links to the site. For business, this is an invaluable tool to understand who is calling before you pick up the phone. Also available is the function "Secretary", which can automatically answer calls of robots-spamers, taking their time and misleading.
The app also features a Child Definition feature, which by installing the app on your child’s phone and connecting it to your account (via Yandex Plus Family), you can see who is calling your child, a powerful parental control tool that protects the child from fraud and unwanted communication.
To activate premium features, just log in to the app with the account you subscribe to, check status under Profile. If you don't have a subscription, the app will offer a trial period, which usually lasts from 30 to 90 days depending on the current stock.
Even without a paid subscription, it remains a market leader thanks to a huge crowdsourcing database, where users label numbers as spam, and this information is instantly available to millions of other people, making it self-learning and extremely effective against new fraud schemes.
