Why you need to identify incoming calls on Xiaomi
Xiaomi MIUI-based smartphones have a built-in numbering feature, but it works limitedly: only shows contacts from the phone book and spam calls through the Mi Security database. Yandex.Number Definition expands these capabilities by pulling up data from a vast database of organizations, delivery services and individuals. This is especially useful for owners of Redmi Note 12, POCO X5 or Xiaomi 13T, who often encounter unknown courier numbers, banks or government services.
The main advantages of Yandex.Definition over the standard solution from MIUI:
- π 50 base+ million numbers (against) ~$10 million for Mi Security)
- π’ Exact definition of organizations (including branches and branches)
- π‘οΈ Filtering fraudulent calls on current schemes of 2026
- π It works even when the Internet is disconnected (caches the latest data)
Important: the service is system-level integrated, so it doesnβt require you to open the app all the time, but on Xiaomi with MIUI 14 and later, there may be conflicts with the built-in determinant, as more in the problem solving section.
Requirements for the service on Xiaomi
Before setting up, check if your device meets the minimum requirements:
| Parameter | Minimum value | Recommended |
|---|---|---|
| Android version | 9.0 Pie | 11+ (for full synchronization) |
| MIUI version | 11 | 12.5/13/14 |
| Access rights | Reading call logs | Auto Start + Background work |
| Free memory | 100MB | 300+MB (for base cache) |
On Xiaomi models with MediaTek processors (e.g. Redmi 10C or POCO M5), the detector may run slower due to the chipsetβs power saving limitations, in which case it is recommended to manually add the app to the battery optimization exception list.
β οΈ Attention: On devices with MIUI Global may require additional permission from Display over other apps to correctly display pop-up notifications about the number.
Method 1: Installation via Yandex.Mail (recommended)
The most reliable method is to activate the determinant through the official Yandex.Mail app, since it has extended system rights, which works on 95% of Xiaomi devices without root rights.
- Install Yandex.Mail from Google Play (version no lower than 23.80).
- Open the app and log in (or create an account).
- Go to Settings. β Number-defining.
- Activate the switch to show the names of subscribers.
- In the window that appears, click Allow to access call logs.
After that, the service will start to work automatically. The first number determination can take up to 3-5 seconds, which is normal, since it is synchronized with the base.

Method 2: Hand-mounted APK (for older models)
If your Xiaomi does not support Google Play Services (e.g. Redmi) 5A on the scaling board, or you are using MIUI China, you can set the determinant through APK-file:
- Download the latest version of Yandex.Definition (version 5.40+).
- Allow installation from unknown sources in Settings β Applications β Special Access Rights β Install unknown applications.
- Install APK and open the app.
- Manually issue licenses: π± Call logs (required) π Auto-start π No battery restrictions
β οΈ Attention: On Xiaomi with MIUI 14 after installation APK You may need to restart the device, otherwise the detector will not appear in the list of applications with call access rights.
What to do if the APK is not installed?
Optimal settings for Xiaomi
To ensure that the determinant works stably and does not conflict with MIUI, configure the following parameters:
Rights and permits
- π Settings β Annexes β Application management β Yandex.Mail/Definition β Rights. β Call logs β Permission.
- π Settings β Battery and productivity β Battery consumption management β Yandex.Mail β No restrictions.
- π Settings β Annexes β Auto-start β Turn on for Yandex.Mail
Determinant settings
In the application Yandex.Mail:
- π΅ Enable Spam Blocking (filters scammers)
- π Activate International Numbers (if you are calling abroad)
- π Turn off the display of advertising (reduces the load)
For models with AMOLED-screens (e.g. Xiaomi) 13 Pro or Redmi K60) It is recommended to disable the animation of pop-up windows in the settings of the determinant - this will reduce battery consumption on the 5-7%.
π‘
If the detector doesnβt show names after setting up, try making a test call to 8 800 250-07-71 (Yandex Support Service) and this forcefully synchronizes the database.
Typical problem solving
Even after you set it up properly, you can have failures, and here are the most common mistakes and their solutions:
| Problem. | Reason. | Decision |
|---|---|---|
| Doesn't show names. | Conflict with Mi Security | Disable the built-in determinant in Settings β Memory and files β Cleanup β Settings β Defining numbers |
| 10+second delay | MIUI background restriction | Add the application to Secure Applications (in battery settings) |
| Not working after the update | Resetting permits | Reinstall the application and grant rights again |
| Shows "Unknown." | No Internet. | Turn on mobile data or check your Wi-Fi connection |
POCO F5 and other HyperOS devices (new shell from Xiaomi) may require additional Display pop-up windows resolution. Find it in Settings β Special Rights β Other permissions.
β οΈ Warning: If after all the manipulations, the detector still doesnβt work, check if your Xiaomi Magisk or other modules that modify system services are installed on your device.
Security and confidentiality
Many Xiaomi users worry about transferring data to Yandex, and this is what really happens when you use a determinant:
- π Not transmitted: contents of calls, SMS, phonebook contacts
- π€ Transmitted: Incoming/outgoing calls (without reference to your account) Call times and durations (for spam statistics) Device model and OS version (for optimizing service)
For additional protection:
- Turn off Personalized recommendations in the settings of Yandex.Mail.
- Use a VPN when you first start up (like Cloudflareβs Warp).
- Regularly clean the app cache through Settings β Applications β Yandex.Mail β Memory β Clear the cache.
On Xiaomi with MIUI 14, you can restrict geolocation access for the determinant, as it is not used to identify numbers. Go to Settings β Privacy β Permits β GeoData β Yandex.Mail and select Opt-out.

Yandex.The detector does not have access to conversation records or SMS β it analyzes only the metadata of calls (number, time, duration).
Alternatives to Yandex.Definition for Xiaomi
If the service from Yandex is not suitable, consider these options:
| Annex | Pluses | Cons | Compatibility with MIUI |
|---|---|---|---|
| Truecaller | Largest room database (300 million+) | Registration is required, lots of advertising | β It's stable. |
| GetContact | Showing names from social media | Questionable privacy policies | β οΈ Need Root Rights to Full Work |
| Mi Security (built-in) | It does not require installation, it consumes battery economically. | Small database, spam numbers only. | β Optimized for Xiaomi |
| Selectordefinition | It is good to determine bank numbers. | It only works for Sber's clients. | β No problem. |
On Xiaomi with MIUI 12.5+, you can use a combined approach: turn on the built-in Mi Security for spam filtering and additionally install Yandex.Definition for identifying organizations.
- Activate Spam Definition in Settings β Memory and Files β Cleanup β Settings.
- Install Yandex.Determinator according to the instructions above.
- In Yandex settings, disable Spam Blocking to avoid duplication.
