Disable the Yandex number determinant on Xiaomi Redmi: a step-by-step guide

Modern Xiaomi smartphones running MIUI shells or the new HyperOS offer users a wide range of pre-installed features aimed at improving comfort and security. One of these features is the integration of Yandex services, which can be activated by default when the device is first turned on or after a system update. In particular, many Redmi owners notice that incoming calls are now accompanied by pop-ups with information about the caller, even if they did not install the corresponding applications themselves.

The need to disable the number detector often arises for various reasons: some are annoyed by the constant visual noise, others are afraid of leaking confidential data, and still others simply prefer to use third-party solutions to filter calls. It is important to understand that the deactivation process can vary depending on the version of the Android operating system and the specific modification of the MIUI shell. In some cases, the settings are hidden deep in the system menu, and in others, the management is through third-party aggregator applications.

In this article, we will discuss in detail all possible ways to eliminate this feature. We will look at both software methods through system settings and working with specific applications of the Yandex ecosystem. It is critical to correctly determine the source of the number, since different system components may be responsible for this on different firmware. Follow the instructions carefully to regain full control of your device.

Analysis of the source of the number determination Xiaomi

Before you start taking active action to disable the function, you need to identify exactly which operating system component is responsible for identifying the subscriber. On Xiaomi Redmi smartphones, it is often not one application that is responsible for this, but a bundle of system services and preinstalled software. Most often the data source is the Security application, which in Chinese and some global versions of firmware is tightly integrated with Yandex databases.

The second likely source could be Google’s Phone app itself or a modified version of it from Xiaomi that has access to cloud-based spam filters. If your device has separate Yandex, Yandex.Browser or Yandex.Disk apps installed, they can also request permissions to access calls and contacts, becoming a data channel. System integration allows these services to work in the background, even if you do not use them directly.

For accurate diagnosis, it is recommended to check the list of recently installed updates or system applications that have permission to work with telephony. Often users themselves inadvertently activate the "Number Define" function in the call settings, wanting to protect themselves from spam, but forget about it after a week. Understanding where this feature lives on your particular device, will save time and avoid unnecessary manipulation of system files.

Disconnection through MIUI and HyperOS system settings

The best and safest way to remove the redundancy is to use the operating system’s regular tools. Redmi smartphone owners should start by checking basic call settings. The algorithm can vary, but the logic remains the same: find the partition responsible for incoming calls and disable the identification options there. This action does not require superuser rights and is safe to guarantee the device.

In modern versions of the shell, the path to the desired configuration often lies through the application management menu, you need to find the component responsible for calls in the list of system applications and clear its data or restrict rights. However, a milder method is to simply switch the toggler in the settings. If you're using a global firmware version, pay attention to Settings. → Annexes → All applications → Phone. → Number-defining.

In some cases, especially on devices with Russian localization, settings can be made in a separate sub-item of the security menu. It is important not to confuse the ad blocker and the number detector. Deactivation should be done for the identification service, so as not to disrupt the other security mechanisms of the smartphone. If the standard path did not lead to the result, go to the next section of the instructions.

Management of services in the Security application

The Security app (a lightning or shield icon) is the central node for managing many of Xiaomi's functions, including call filtering. This is where integration with Yandex databases most often hides. To access advanced settings, you need to open the app and find the Antispam or Lock section. This menu usually has a switch that activates cloud-based number checking.

Inside the anti-spam menu, you should look for the "Update databases" or "Definition settings." Often, a source of data has already been selected there, such as Yandex or Tencent. Disabling the source or completely deactivating the "Understanding Number Identification" function will solve the problem. Remember that after resetting or updating the system, these parameters can return to default values, so it is worth checking periodically.

If you can't find the right switch, try clearing the cache of the Security app itself. Sometimes temporary configuration files can cause display errors or feature sticking. To do this, go to Settings → Apps → All Apps → Security → Memory → Clear. This action is secure and won't delete your personal data, but resets the filters to factory ones.

⚠️ Note: When cleaning the data, the Security app may reset all your personal lock settings, including the contact blacklist, and it is recommended to pre-screenshot important numbers or export the lock list if such a feature is available in your version of the software.

Settings within the Yandex ecosystem applications

If your Xiaomi Redmi has Yandex apps installed, they can activate their own defining functions by obtaining the appropriate permissions during installation. In particular, the Yandex application (with a yellow letter I) or Yandex.Browser often have built-in modules for working with telephony. To disable this function, you need to go to the settings of the aggregator application itself.

Open the Yandex app, click on the profile icon or menu (three bars) and go to Settings. Find the subsection related to calls or security. There should be a number detector or spam lock. Turn the switch to off. It's also worth checking the Android permissions for this application: in the phone's system settings, find Yandex and make sure it doesn't have access to Phone or Contacts unless you plan to use these features.

It is important to note that deleting the Yandex application may not immediately remove the determinant widget if it was embedded in the system at the firmware level. APK-So the first step is always to program deactivate through the settings, and then delete the application if you don't need it for other tasks.

Comparative table of disconnection methods

To make it easier to choose the best way to solve the problem, we have systematized the main methods into a table, each of which has its own characteristics, level of complexity and effectiveness depending on the specific model of your Redmi smartphone and the version of Android.

As you can see from the table, the safest and most effective method is to use the Security app, which is the path recommended for most users who do not want to go into the technical wilds. However, if this method has failed, a combination of methods (for example, disabling settings plus cleaning data) usually leads to success.

Forced Stop and Removal of Updates

In situations where standard switches don’t work or the number detector function compulsively returns after each reboot, a more radical method can be used: a rollback to the factory version of the system component. This is especially true if the problem occurs after another automatic update of Xiaomi’s system, the essence of the method is to remove updates to the Phone or Security application.

To do this, go to Settings → Applications → All apps. Find Security or Phone in the list. Click on the app name and select Remove Updates (usually in the lower right corner or in the three-dot menu) from the menu that opens.

Once the process is complete, the smartphone can behave unusually: icons can be rebuilt and settings reset. This is a normal reaction. The main advantage of this method is that it removes new features that may have been added by developers in recent versions of the software, including aggressive integration of Yandex services. After the updates roll back, be sure to recheck the settings so that the function does not activate again on the first connection to Wi-Fi.

💡

Before removing system application updates, make sure you have a stable internet connection in case components need to be rebooted, or vice versa, turn off the network so the system doesn’t start automatically updating immediately after a reset.
