Owners of Xiaomi, Redmi and POCO smartphones often face intrusive spam and calls from scammers. The built-in protection mechanisms in the shell of MIUI or HyperOS work well, but third-party software is often required to fully identify a subscriber. Installing a specialized number detector is the first step to digital peace and security of your device.
Modern phones have powerful processors and enough RAM to cope with the background work of database numbers without noticeable loss of performance. It is important to understand that the number detector works not just as a reference, but as an active filter that analyzes incoming traffic in real time. In this article, we will discuss in detail which applications are best integrated with the security system Xiaomi and how to set them up correctly.
The choice of a particular solution depends on your personal preferences for privacy and usage habits. Some prefer the Google ecosystem, others trust local giants like Yandex. Regardless of the choice, the right configuration of permissions will be the key to effective software. Let's look at the basic stages of preparing and implementing protection.
MIUI's built-in capabilities and limitations
The MIUI shell and the new HyperOS already contain a basic module for protection against unwanted calls, which is based on local lists and sometimes connects to Tencent or Google cloud services. However, for users from CIS countries, the functionality may be limited or require complex regional configuration. To activate the basic protection, you need to go to the Security application and find the Antispam section.
Here you can manually blacklist or block hidden numbers. The system allows you to create rules, such as blocking all calls not saved in contacts, which can be useful during periods of active telephone terrorism.However, automatic identification of unknown subscribers (such as "Food Delivery" or "Courier Service") without third-party applications often does not work or does not work correctly in our regions.
⚠️ Warning: Completely blocking all unknown numbers may cause you to miss an important call from a doctor, courier or employer who calls from a new number.
To expand the functionality, many users are trying to switch from a region of the phone to India or Indonesia, where databases are richer, but this action can affect the operation of other system applications and advertising integrations.
Selection of the optimal application-definition
The Caller ID application market is saturated, but not all of them are equally good friends with Xiaomi’s aggressive energy saving system, with Yandex.Caller, Google Phone (with Number Determiner enabled) and Kaspersky Who Calls all having their own strengths: Yandex databases are most relevant for Russia, while Google is better at recognizing international numbers and spam bots.
When choosing, consider the weight of the application and the number of permissions requested. Heavy determinants can conflict with the system interface of calls, causing delays in response to a call. Lightweight alternatives such as NumBuster or CallApp offer wide functionality, but are often overloaded with advertising in free versions. For Xiaomi owners, stability in the background is important.
- 📱 Yandex.Caller is ideal for Russia, excellent integration with Yandex.Navigator and Alice, but requires an account.
- 🛡️ Kaspersky Who Calls – minimalist design, high reliability of bases, no unnecessary advertising and society.
- 🔍 Google Phone – native integration in Android, but requires the inclusion of additional features in the settings of Google account.
This means that when you install an app, you also share your phone book (if you agree) to add to the common base, and if you are critical to contact privacy, choose apps marked “no contact transfer” or use local solutions.
💡
When installing a number determinant on Xiaomi, always download the app only from the official Mi GetApps store or Google Play Store. APK-Files may contain malicious code that steals passwords from banking applications.
Step-by-step instruction: installation and initial setup
The process of installing a third-party determinant on Xiaomi requires care, as the system will actively resist transferring rights to a new application. After downloading the selected software from Google Play or GetApps, run it. The first step is to ask the system to make the application the default application for calls. This is necessary so that the detector can intercept the incoming call before you pick up the phone.
The next critical step is permissions. You'll need to allow access to contacts, call logs, and most importantly, phone access. Without that, the app won't be able to display information about the caller on the lock screen. In modern versions of Android and HyperOS, you may also need permission to "overlay over other windows" to display a search widget or pop-up notifications.
☑️ Checklist of correct installation
Once you have set up the basic setting, the detector interface will replace the standard Xiaomi call, and you will see the call history in the new design, and at this point it is important to check if unknown numbers are displayed, and you can use the in-app search function or ask someone to call you from another number that is not stored in the contacts.
| Parameter | Yandex. Caller. | Kaspersky Who Calls | Google Phone |
|---|---|---|---|
| Russian Federation database | Very big. | Medium | Medium |
| Advertising | Aye (in the interface) | No. | No. |
| Recording of conversations | Got it (automatically) | No. | Depends on the region. |
| Impact on the battery | Average. | Low. | Low. |
Set up auto-start and work in the background
The most common problem Xiaomi owners have is that the detector stops working within hours of installation, which is due to aggressive battery optimization, which kills background processes to save energy. To keep your number detector running 24/7, you have to manually remove it from the list of optimized applications. Without this step, all previous actions lose meaning.
To start, go to Settings → Applications → All applications. Find the set determinant (e.g. Yandex.Caller) in the list. Go to Activity Control or AutoRun. You need to turn on the AutoRun switch, which will allow the system to start the application immediately after the phone is turned on.
Next, in the same app settings menu, look for Battery Savings (or "Battery"). The default is "Energy Savings." You need to change this setting to No Limits. This is a critical setting that prevents MIUI from forcibly shutting down the detector process even if the screen is off for a long time.
⚠️ Note: If you do not set the No Limits option, the operating system may complete the process of the determiner during an incoming call, and you will only see a standard call screen without identification.
It is also recommended to fix the application in memory (lock in the open app menu), although in new versions of HyperOS this does not always work effectively. The main thing is to set up autostart and no battery limitations.
💡
Without setting the "No Limits" for the battery, the number detector on Xiaomi will not work. This is a system feature, not an application error.
Conflict Resolution: Two Calls on the Same Phone
Installing a third-party detector often leads to conflict, as two callers appear on the phone: the standard one from Xiaomi and the new one. Android allows you to use only one application by default. If you want to keep the familiar interface of Xiaomi, but use the databases of a third-party application, the situation becomes complicated.
Some determinants, like Yandex, can work in tandem with a standard call, but require special compatibility modes in their settings. However, the most stable option is to still use the call of the detector itself. It may look different, but it guarantees 100% number determination. Google or Yandex interface is flexible enough to configure large buttons and a convenient theme.
If a conflict does occur (e.g., a call sends out an error or a black screen), try clearing the cache of both the standard Phone and the new determinant. You can do this through Settings → Applications → Application Management. Select the application, click Storage and select Clear Cache (not data to avoid losing history).
- 🔄 Resetting call settings: In extreme cases, in the settings of the "Phone" application itself, find the "Reset settings" or "Restore silence" button".
- 🚫 Miui Optimization Disconnection: In rare cases, optimisation disabling helps MIUI In the "Developers" menu, but this may disrupt other functions.
- 📞 VoIP use: Some determinants suggest using their communication channels, which may conflict with the use of the Internet. SIM-Turn off this function in the application settings.
