Modern smartphones are full of advertising and spam, and owners of Xiaomi Redmi devices face this problem especially acutely. Built-in mechanisms to protect against unwanted calls often are not effective enough or require complex configuration, which is why installing a third-party number detector becomes a necessity for comfortable use of the gadget.
The most popular solution in the Russian market is Yandex, which has a huge database. However, the MIUI operating system installed on Redmi smartphones is known for its aggressive battery saving, which leads to applications often being unloaded from memory, no longer identifying callers.
In this tutorial, we will discuss all the steps in detail: from downloading the current version to fine-tuning the system limitations of Android, you will learn how to make the service work even when the application is closed and why the standard installation is not enough for full protection.
Installation and initial configuration of the application
The first step is to download the software from the official Google Play store. Xiaomi users should be careful, as the store may have similar applications with similar names, but from other developers.
Once installed, you need to run the program and log in through your Yandex ID account. This is required to synchronize the number database and access advanced features such as spam blocking. Without authorization, the functionality will be limited to only the basic determinant, which reduces the effectiveness of protection.
During the initial launch phase, Android will request a number of critical permissions, such as access to contacts, call logs, and telephony, and failure to provide any of these items will result in the service’s core functionality being disabled.
☑️ Primary setting of Yandex
It's important to note that the interface may vary slightly depending on the version of MIUI and the program itself, but the logic of action remains the same for all Redmi models. If you've previously used other determinants, their databases may conflict, so it's a good idea to remove old applications.
Configure access rights in the MIUI system
The MIUI Operating Shell has its own permission management mechanisms that duplicate the standard Android settings. To make the number detector work correctly, you need to go to Settings → Applications → All applications. Find Yandex in the list and go to the menu “Other permissions” or “permissions”.
All available switches should be activated, especially those that are connected to displaying over other windows and accessing the phone. Without permission to "display on top of other applications", a pop-up with the name of the caller will not appear during the incoming call.
⚠️ Attention: In new versions MIUI You may need to manually allow access to AutoRun. If this option is disabled, the system will force the detector to stop working after restarting the smartphone.
Also, check your privacy settings. In some cases, Xiaomi’s antivirus protection can block access to your contact list, and make sure that the security section does not prohibit reading the phone book for the software you choose.
To be sure, you can use the built-in Settings Search to make sure you're right, type "permissions" in the search bar and select Application Permissions Management, which will quickly find and fix missing items without wandering through the menu.
Battery optimization and background work
The most common problem on Redmi smartphones is the “killing” of background processes by the power saving system. To keep the Yandex number detector running constantly, you need to remove it from the list of optimized applications. Go to the Settings → Battery and Performance menu (or simply “Battery”).
Find the tab "Activity Control" or "App Battery Consumption." In the list, search Yandex and change the mode to "No Restrictions," which will prevent the system from forcibly closing the application, even if it is not actively used for a long time.
- 🔋 Turn off energy savings for Yandex application in battery settings.
- 🚀 Add the app to auto-run via the Safety app (green lightning icon).
- 🔒 Lock the app in memory so it doesn’t unload during cleaning.
To lock in memory, run the application, then go to the screen of running tasks (swipe from the bottom up and hold or menu button). Find the Yandex window and pull it down until the lock icon appears. Now, when you clear the memory with the Crack button or swipe, the application will remain in the system.
💡
Periodically check the autostart list after major MIUI updates, as the system can reset user power saving settings to factory values.
Integration with system call and Google
Xiaomi smartphones can use different types of dialers: standard MIUI Dialer or Google Phone. The integration process depends on which interface is used to make calls. Most modern models have a Google call installed by default.
If you use Google Phone, you'll need to go to the settings of the Phone app itself after you install the ID, and in the "Number Defineer" or "Caller ID & spam" section, you'll need to select Yandex, which will allow you to display information directly in the call interface.
If you use a native MIUI call, the settings may be deeper, sometimes you need to activate the number service in the call settings section, and the system may request confirmation to use the service by default.
| Type of caller | The path to settings | Action required |
|---|---|---|
| Google Phone | Three points → Settings → Definition of the number | Select Yandex |
| MIUI Dialer | Call settings → Antideterminator | Activate service |
| Third-party (Truecaller) | Application settings | Set by default |
Keep in mind that when you update the system or the application itself, the settings may be confused, and it is recommended to periodically check which service is chosen as the main source of caller data.
Solving Typical Problems and Errors
Despite the correct setup, users may encounter situations where the determinant stops working, often due to updating the Android System WebView components or the Google Play service itself, in which case cleaning the cache of the Yandex application helps.
Another common reason is conflict with other apps that have access to the phone, and if you have multiple detectors or blockers installed, they can prevent each other from correctly intercepting calls.
⚠️ Note: If after the update MIUI You've lost your access settings, don't rush to delete the app. First, check the "Special Features" section, sometimes new restrictions for background services appear there.
In rare cases, the problem is that the contact database is damaged, and if the contact ID shows numbers but doesn't store history or see names from the notebook, try re-authorizing the contact readout, sometimes removing the app, restarting the phone, and installing it again.
What if the numbers are determined but not blocked?
Additional functions and advice on use
In addition to simply identifying a number, the service offers a number of useful features that are worth activating, such as the ability to tag numbers with "Courier", "Taxi" or "Spam", which helps to build a personal database and improves overall statistics for all users.
Antispam is also available, which can automatically drop calls from tagged numbers, and activate it carefully so as not to miss an important call from a stranger who has not yet been listed as spam.
- 📞 Customize silence for unknown numbers if you are only waiting for a call from contacts.
- 📝 Use tags to categorize frequent calling organizations.
- 🔍 Periodically check the history of blocked calls for false positives.
For advanced users, synchronization with a Mi Band or Amazfit smartwatch is available. When set up correctly, a notification of an incoming call with the name of the subscriber will come on the wrist, which is very convenient when the phone is in the bag or in another room.
💡
The main secret of stable operation is an integrated approach: you need to configure the application itself, the MIUI system, and the battery parameters at the same time.
