Modern smartphones, such as Xiaomi Redmi 9 Pro, have powerful functionality, but often suffer from intrusive spam and fraudulent calls. Users are looking for effective ways to identify unknown callers without extra costs. A popular solution is a service from the search giant that integrates into the calling system. Installing and activating this function has its own nuances on the shell MIUIthat must be taken into account for correct operation.
In this guide we will analyze all the steps necessary to Caller ID start working automatically. You'll learn how to bypass Android security restrictions and configure permissions. This will allow you to see the caller's name even if it is not in your phone book. The setup process takes only a few minutes, but requires attention to detail.
Effective anti-spam protection is not just a convenience, but a necessity in today's digital noise environment. Proper application configuration will help weed out unwanted calls before they even bother you. We will look at both standard installation methods and solutions to specific problems that arise specifically on devices Redmi.
Checking compatibility and system requirements
Before starting installation, it is critical to make sure that your device meets the minimum service requirements. Model Redmi 9 Pro works on Android 10 with MIUI 11 or 12 shell, which fully supports modern identification services. However, the operating system version must be at least Android 8.0 for the correct display of widgets and background processes.
It is worth noting that Caller ID requires a stable Internet connection at the time of an incoming call. The number database is stored in the cloud, so offline operation is not possible. Make sure that your tariff plan has mobile data enabled or you are in a Wi-Fi network coverage area.
⚠️ Attention: Some global versions of MIUI firmware may not have pre-installed Yandex services. In this case, you will need to manually download the installation file.
Also check the amount of free RAM. Although the application is not heavy, the system needs to allocate resources to quickly process the incoming signal. Closing background tasks before the first setup will help avoid possible delays in displaying the subscriber's name.
Downloading and installing the application
The most reliable way to get the latest version of the software is to use the official one store Google Play Market. In the search bar, enter the name of the service and select the application from the developer Yandex Apps. Click the "Install" button and wait until the download completes. This method guarantees that you receive verified software without built-in advertising or malicious modules.
If for some reason the Google store is not available, you can use an alternative source. Download APK file from the official website of the developer. To install third-party software on Xiaomi Redmi 9 Pro you will need to allow installation from unknown sources in the security settings.
- 📥 Open the browser and go to the official download page.
- 🔒 Allow installation of applications from this source in the system that appears window.
- ⚙️ Run the downloaded file and follow the instructions of the installation wizard.
- ✅ Wait for the icon to appear on your desktop.
After successful installation, do not launch the application immediately. First you need to grant it special rights, without which the functionality will be limited. The Android system strictly controls access to telephony, so the initial launch will require your authorization.
If you download an APK file, always check the digital signature of the developer to avoid fakes.
Initial setup and authorization
Run the installed application. On the start screen you will be asked to log into an existing account or register a new one. Having an account Yandex ID is required to synchronize settings and use the cloud database of spam numbers. Enter your username and password in the appropriate fields.
The key step is to grant permissions. The app will ask for access to your contacts, call history, and microphone. For the function to work Number identification the first two points are critically important. Without access to the call log, the service will not be able to intercept incoming calls and check them against the database.
| Permission type | Status | Purpose |
|---|---|---|
| Contact | Required | Checking with personal phone book |
| Phone (Calls) | Required | Incoming call interception |
| Notifications | Recommended | Display name on lock screen |
| Location | Not required | Not used for identification |
The system may request permission to display on top of other windows. This is necessary so that the caller's name appears on top of the lock screen or active application. Confirm this action in the system dialog. If you skip this step, the detection will only work within the application itself, and not during a call.
Integration with the MIUI system compositor
On smartphones Xiaomi the integration process has its own characteristics due to the aggressive energy-saving policy of the MIUI shell. After granting basic rights, you need to go to the settings of the application itself. Find the “Caller ID” section and activate the switch to the “On” position.
Next you need to configure work with the system dialer. Go to your phone settings, “Applications” section, find “Phone” (system application). In the “Caller ID” or “Additional services” item, select the installed Yandex application as the main identification service. The path may look like Settings → Applications → Phone → Caller ID.
⚠️ Attention: The settings interface may differ depending on the MIUI version. If you do not find the item in the phone menu, try setting it up through the Yandex application itself.
In some cases, the system may reset the selection to default. To avoid this, pin the application to memory. Open the menu of running applications, find the determinant window, hold it down and click on the lock icon. This will prevent the system from closing the process to save energy.
☑️ Setting up integration
Setting up spam blocking and filters
One of the main functions of the service is not only identifying, but also blocking unwanted calls. In the application settings, go to the “Antispam” section. Here you can activate automatic blocking of numbers flagged by other users as fraudulent or advertising.
You can flexibly configure filters. Blocking by category is available: taxi, delivery, telemarketing. It is also recommended to enable the “Block hidden numbers” feature if you do not expect calls from such subscribers. This will significantly reduce the number of distractions during the day.
- 🚫 Activate ad blocking.
- 🛡️ Enable protection from financial fraudsters.
- 📞 Add your personal blacklists.
- 🔕 Set the silence for unknown numbers (optional).
It is important to regularly update spam databases. This usually happens automatically, but you can force the update in the application settings. Fresh databases allow you to identify new fraud schemes that appear daily.
Solving problems with display and operation
Often users are faced with a situation where the application is installed, but the name of the caller is not displayed. In 90% of cases, the problem lies in the MIUI power saving settings. The system “kills” the background process of the determiner, considering it unnecessary. It is necessary to prohibit autorun and background operation for this application.
Go to Settings → Battery and performance → Select applications. Find the caller ID in the list and set the mode to “No restrictions”. This will allow the app to run continuously even when the screen is off. Without this step, the definition will be unstable.
What to do if the name does not appear?
Try clearing the application cache and restarting your smartphone. Also check to see if you have accidentally revoked your phone's privacy settings.
Another reason could be a conflict with another installed definer. Android allows only one caller ID service to be active at a time. If you have a blocker installed from another manufacturer, remove it or disable its detection function before activating Yandex.
The main reason for failures on Xiaomi is aggressive energy saving. Be sure to set the application to “Unlimited” mode.
Frequently asked questions
Is it free to use Yandex caller ID?
The basic caller ID function is free for all users. However, the automatic spam blocking feature and advanced filters may only be available with a Yandex Plus subscription or as part of a trial period.
Do my contacts see that I have installed this application?
No, the installation of the application is private. Your contacts will not receive any notifications. However, if you allow access to contacts, your saved names can be used to replenish the general database (with anonymized data).
Does the identifier work without the Internet?
No, the service requires an active network connection. The database of numbers is too large to store it locally on the device, so the request is sent to the server at the time of the call.
Is it possible to use the identifier on two SIM cards?
Yes, the application supports working with two SIM cards at the same time. The detection will work for both lines, unless the phone settings limit the use of the detector for only one SIM.
