Yandex number detector on Xiaomi: how to turn on and configure in 5 minutes

Xiaomi Android-based smartphones often face problems with third-party number detectors, especially when it comes to Yandex. Users complain about the lack of notifications about incoming, broken prompts or complete disregard by the application of calls. The reason lies in the aggressive optimization of MIUI, which blocks the background activity of applications, and in the peculiarities of integrating Yandex services with the Xiaomi shell.

In this article, we will discuss three working ways to enable Yandex number detector on any Xiaomi smartphone (including Redmi, POCO and Black Shark) relevant for 2026, focusing on setting permissions, circumventing MIUI 14/15 restrictions, and solving common errors like “Number Service is not available.” All instructions are tested on Android 12-14 devices and newer versions of applications.

Why does the Yandex-definition not work on Xiaomi?

The problem lies in three key points:

• 🔄 Optimizing the battery: MIUI The default limiting background activity of all applications except system ones. Yandex-definition requires constant access to calls, which the shell perceives as “unnecessary power consumption».
• 🛡️ Android Permits: Starting with Android 10, To determine the numbers, you need not only permission to call, but also a special right. READ_CALL_LOG, which MIUI hides in deep settings.
• 🔗 System Definition Conflict: Some Xiaomi firmwares have a built-in determinant (e.g. Mi Caller) ID), which blocks the operation of third-party services.

The Yandex Settings service officially only supports numbers from Russia, Belarus, Kazakhstan, Uzbekistan and Ukraine. If your smartphone is purchased in another region (for example, the global version of the POCO X5 Pro), the service may refuse to work even with the right settings.

Method 1: Basic configuration through the Yandex application

Let’s start with the simplest method, which works in 60% of cases, and is suitable for users who already have the Yandex application installed (with a browser, maps or mail).

1. Open any application from Yandex (for example, Yandex.Browser).
2. Go to profile (the person icon in the upper right corner) → Settings → Number Definiter.
3. Activate the switch to show the names of the callers.
4. Click Allow access to calls and follow the system instructions.

If after these actions the determinant did not work, check:

• 📱 Application version: Update Yandex.Browser or Yandex to the latest version in Google Play.
• 🔄 Background Activity: Go to Settings → Annexes → Application management → Yandex and turn on Auto Start and Background Activity.
• 🔔 Notifications: In the same app settings, check that notifications are enabled and not blocked.

⚠️ Attention: If in the settings MIUI No Background activity, so your firmware is using an outdated interface. Try an alternative path: Settings → Battery and productivity → Battery consumption management → Yandex → No restrictions.

Method 2: Manually Adding Permissions via ADB (for Advanced)

If the basic setup doesn’t work, you’ll have to manually assign critical permissions to the Yandex app, which requires connecting your smartphone to your computer and using the Android Debug Bridge (ADB), which works on all versions of MIUI, but requires caution.

What you need:

• 🖥️ Computer with installed ADB Tools.
• 📱 Included debugging by USB on a smartphone (path: Settings) → The phone. → Version. MIUI → 7 times to tap according to the version → return to additional settings → For developers → Debugging by USB).
• 🔌 USB-TypeC Cable (preferably original).

Instructions:

1. Connect your smartphone to your computer and confirm your trust in the device.
2. Open the command prompt (cmd on Windows or Terminal on macOS/Linux) in the folder with ADB.
3. Enter the commands alternately (replacing ru.yandex... with the current package of your Yandex application, which can be found through adb shell pm list packages | grep yandex):

adb shell pm grant ru.yandex.android.browser android.permission.READ_CALL_LOG


adb shell pm grant ru.yandex.android.browser android.permission.PROCESS_OUTGOING_CALLS




adb shell pm grant ru.yandex.android.browser android.permission.READ_PHONE_STATE

After completing the commands, restart the smartphone. The detector should work within 5-10 minutes.

⚠️ Note: Some Xiaomi firmware (especially Chinese) after permission reboot ADB To fix the changes, follow the command: adb shell cmd appops set ru.yandex.android.browser android:read_call_log allow This command links permission to application at system level.

Method 3: Use of an alternative application "Yandex.Phone"

If the first two methods didn’t work, try installing a specialized application called Yandex.Phone (formerly Yandex.Calls) designed specifically for number definition and has advanced MIUI compatibility settings.

Algorithm of action:

1. Remove all existing Yandex applications (browser, search, mail) through Settings → Applications.
2. Download Yandex.Phone from Google Play.
3. When you first start, allow all requested rights, including access to the call log and call management.
4. In the application settings, turn on: 📞 Definition of incoming 🔔 Spam notifications 🔄 Background work (link leads to settings) MIUI)

This method has the advantage of automatically adjusting permissions through the application’s internal mechanisms, but some devices (such as the Redmi Note 11 with MIUI 13) may need to manually enable the Imaging over other windows in the special features settings.

💡

If the detector is unstable after installing Yandex.Phone, try disabling the built-in Mi Caller ID. Go to Settings → Applications → Application Management → System Applications → Caller ID and click Disable (or Remove Updates if the off button is inactive).

Compatibility table: Which Xiaomi models support the determinant?

Not all Xiaomi smartphones work equally well with the Yandex-definition, as follows: data on popular models (based on tests of 2026):

If your model is not in the table, focus on the MIUI version:

• 🟢 MIUI 14/15: Supported with minimal settings.
• 🟡 MIUI 12/13: Manual permissions are required through ADB.
• 🔴 MIUI 11 and below: Probability of working ~30%, it is recommended to update the firmware.

Decision errors

Even after you set it up correctly, users are going to have errors, and we're going to look at the most common ones.

1. “Number Service Unavailable”

The reason: conflict with the system determinant or lack of Internet.

Decision:

• 🌐 Check the connection to the network (the detector requires access to the Yandex database).
• 🔄 Reinstall the Yandex application and re-set the settings.
• 📱 Turn off the built-in Mi Caller ID (See the instructions in the spoiler above).

2.The detector works, but does not show names

Reason: Lack of permission to call log or blocking notifications.

Decision:

1. Go to Settings → Applications → Yandex → Permissions and turn on the Call Log.
2. In the same settings, check that notifications are not blocked.
3. Clear the cache of the application (Settings → Applications → Yandex → Clear the cache).

3.The detector stopped working after the MIUI update

Reason: Resetting permits or changing energy saving policies.

Decision:

• 🔋 Re-set Background Activity and Auto Start.
• 🔄 Follow the commands ADB (see method 2).
• 📲 Install Yandex.Phone instead of the standard application.

💡

If none of the methods worked, check the regional settings of the smartphone. Yandex-determiner can be blocked if the phone settings indicate a region outside the support zone (for example, Europe or China). Change the region to Russia in Settings → Additional → Region and restart the device.
