In the modern world, spam calls and fraudulent schemes have become a real scourge for mobile device owners. Every day we receive dozens of calls from unknown callers offering “profitable loans” or introducing themselves as bank employees. The solution to this problem was technology AON, or automatic number identification, which is now available not only to corporate clients, but also to ordinary smartphone users.
The Company Yandex offers one of the most powerful solutions on the market - the Yandex anti-spam service, which integrates directly into the calling system of your Androiddevice. Enabling this feature allows you not only to see the name of the caller, but also to automatically block unwanted calls, saving your time and nerves. In this article, we will analyze in detail the process of installing and configuring the application, and also answer complex technical questions.
The process of activating protection takes only a few minutes, but requires care when providing permissions. Incorrectly setting up access to contacts or call logs can result in the identifier simply not working correctly. We will consider all the nuances so that you can get maximum efficiency from the service without unnecessary difficulties.
Preparing your smartphone and selecting the application version
Before you start setting up AON, you need to make sure that your device is ready to work with services Yandex. First of all, check the operating system version Android. For stable operation of the caller ID, it is recommended to use versions no lower than 8.0 (Oreo), although the basic functionality may be available on older builds.
There are two main ways to obtain the caller ID functionality. The first option is to install a separate application “Yandex with anti-spam protection”. The second option is to use built-in functions in proprietary shells of some manufacturers, such as Xiaomi or Huawei, where technologies Yandex are already integrated at the system level.
If you have a standard Android without pre-installed services, you will need to download the application from the official store Google Play. Make sure you have enough free memory on your device, as the number database requires space to cache information about frequent calls.
Before installation, clear the Google Play store cache if the application is not found by search or is not updated to the latest version.
Pay attention to the model of your smartphone. Some Chinese manufacturers aggressively optimize the operation of background processes, which can lead to the detector being disabled at the most inopportune moment. In such cases, additional power consumption settings will be required.
Installation process and initial setup
Download the Yandex anti-spam application from the store Google Play and run it. When you first start it, the system will ask you to log in to your account Yandex ID. This is a prerequisite for synchronizing settings and using the cloud database of numbers. If you do not have an account, you can create one directly during the installation process.
After authorization, the application will ask for a number of critical permissions. Without providing access to the call log and contacts, the function Caller ID will not work. The system should be able to analyze the incoming number in real time and compare it with the database.
At the setup stage, you will be asked to select the protection level. You can limit yourself to just number identification or enable full spam blocking. It is recommended to immediately activate filtering of advertising calls so as not to be distracted by them in the future.
☑️ Initial Caller ID setup
It is important to read permission requests carefully. If the system requests access to geolocation or microphone without an explicit need for the detector to work, this may be a sign of a conflict with other installed apps. In normal operation Yandex requests access only to telephony and contacts.
Setting up integration with system dialing
The most difficult stage for many users is third-party integration determinant with the native “Phone” application. In modern versions Android (starting from 9.0), Google has tightened the rules for working with calls, requiring that calls be managed by only one application.
To AON displayed directly on the screen during an incoming call, you need to make an application Yandex default application for working with the dialer. Go to Settings → Applications → Default applications → Assistant and voice input or Settings → Calls, depending on your firmware version.
Select “Yandex with spam protection” from the list. After this, the incoming call interface may change slightly, adopting the application style Yandex. This is normal behavior and ensures that the number database will be checked before you pick up the phone.
| Action | Android settings menu | Expected result |
|---|---|---|
| Change dialing numbers | Settings → Default applications | Calls are processed by Yandex |
| Access to contacts | Settings → Applications → Yandex → Permissions | Displaying names from the address book |
| Working in the background | Settings → Battery → Optimization | Stable operation without freezing |
| Notifications | Settings → Notifications → Yandex | Information about blocked calls |
If after changing the default application you no longer hear beeps or the call does not go through, try restarting the device. In rare cases, resetting the network settings is required, but this is a last resort.
What to do if the call interface has become inconvenient?
You can return the standard dialing, but then Caller ID will only work as a notification after a missed call, and not during the call. For complete protection, it is better to get used to the new interface.
Fine-tuning filters and blacklists
After successful integration, you need to customize the filters to suit your personal needs. Universal settings can block useful calls, for example, from couriers or government employees, which are sometimes mistakenly marked by users as spam.
In the application settings section you will find blocking categories: “Advertising”, “Surveys”, “Fraudsters”, “Sales”. It is recommended to leave blocks for scammers and intrusive advertising active, and set categories like “Food delivery” or “Taxi” to “Warn” mode, but not block.
The function Black List allows you to manually add specific numbers that you want to ignore forever. The “Silent Mode” function is also available for unknown numbers, when the phone does not ring, but simply vibrates or silently displays a notification.
⚠️ Attention: Be careful when enabling the “All unknown numbers” filter. You may miss an important call from a doctor, teacher, or emergency services using a hidden number or a new phone.
Check your blocked call log periodically. If you see legitimate numbers there, be sure to add them to the white list or change the category in the common database to help other users.
Flexible filter settings are more important than total blocking: it is better to see a warning about possible spam than to completely lose contact with the outside world.
Solving problems with working in the background
One of the most A common reason why Caller ID stops working is the aggressive energy saving built into shells Android. Smartphone manufacturers often “kill” background processes to extend battery life, which is critical for caller ID.
To prevent this, you need to add the application Yandex to the exceptions of the energy saving system. The path to this setting may differ: on Samsung this is Settings → Device maintenance → Battery → Optimization, and on Xiaomi — Settings → Battery and performance → Select applications.
Find “Yandex with spam protection” in the list and select the “No restrictions” or “Do not optimize” option. This will allow the application to constantly scan for incoming calls, even if the phone screen has been off for several hours.
⚠️ Warning: Disabling battery optimization for an application may slightly increase battery consumption, but this is a necessary price for stable anti-spam protection.
Also check your auto-start permission. Some firmwares (for example MIUI or EMUI) have a separate "Autostart" switch, which must be activated for the correct operation of telephony services.
Why does Caller ID work with a delay?
If the number is identified 2-3 seconds after the start call, it means that the application was “put to sleep” by the system. Check your background activity settings and background permissions.
Data privacy and security
Using caller ID involves transferring data about your calls to the service servers for analysis. Many users rightly wonder about the security of personal information. Yandex uses anonymized data to replenish its database of spam numbers.
When you install the application, you agree that information about incoming calls from unknown callers will be used to improve the quality of filtering. However, the contents of your conversations and personal contacts from your address book are not transmitted to third parties in clear text.
For maximum privacy control, you can disable the sending of statistics in the application settings, although this may reduce the effectiveness of detecting new types of fraud. Each user chooses the balance between convenience and privacy himself.
⚠️ Attention: Data processing conditions and service functionality may change. We recommend periodically checking the “Privacy Policy” section in the application or on the official website of the developer.
Remember that no caller ID gives a 100% guarantee. Fraudsters constantly change numbers using spoofing technologies. Therefore, critical thinking and caution when talking with strangers remain the main tools of protection.
Regularly update the Yandex Anti-Spam application. New versions contain current databases of scammer numbers and bug fixes for working with new versions of Android.
Frequently asked questions (FAQ)
Does the included Caller ID affect the cost of my calls?
No, using the Yandex Anti-Spam application is free and does not affect the tariffs of your mobile operator. Only a minimal amount of Internet traffic is consumed to update the number database if the offline mode is not enabled.
Can I use Caller ID if I have two SIM cards?
Yes, the application supports working with two SIM cards. However, you need to make sure in your Android settings that the default calling app handles calls from both cards correctly. Sometimes you need to manually select which card is the main one for making calls.
Why does the application not see the number, although it is in the spam database?
This can happen if the application does not have the right to read the call log or if it was closed by the energy saving system. It is also possible that the number was added to the database quite recently and has not yet been synchronized with your device.
How to disable Caller ID if I am tired of it?
To disable it, go to the application settings and select “Disable protection” or simply delete the application from the device. After this, do not forget to return the standard “Phone” application as the main one for making calls in the Android system settings.
Does caller ID work without the Internet?
The basic function of identifying known spammers works primarily through the cloud. Without the Internet, the application will only be able to show those numbers that are already cached in the phone's memory, but will not be able to check new unknown numbers in real time.
