Yellow Pages on Xiaomi: functionality, risks and configuration

Redmi and Poco smartphone owners often face incomprehensible system processes that consume resources or raise security questions. One of these components is the Yellow Pages app, which is built into the MIUI or HyperOS shell by default. Many users mistaken it for malware or just “junk” taking up space in memory, but in fact it is a functional service integrated into the phone book.

The main purpose of this component is to automatically identify unknown subscribers and sort contacts into categories, like paper “yellow pages” with advertising services. However, in the digital world, its functions have expanded: it can now block spam, search for organizations nearby and synchronize data with the company’s cloud services. Understanding that Yellow Pages processes geolocation and contacts to find the nearest service centers will help you make an informed decision about its use.

In this article, we will take a closer look at the architecture of the service, assess the privacy risks, and take a step-by-step look at how to deactivate it completely, why removing this component could affect the way a standard call works, and what alternatives exist for privacy-conscious users.

What is the Yellow Pages System App?

Technically, Yellow Pages is a system aggregator application that, in the Xiaomi ecosystem, is responsible for the advanced functionality of the phonebook. Unlike a simple contact list, it connects to online databases to identify incoming calls from organizations, delivery services and government agencies. If you get an unknown number, this module tries to match it with a global registry entry.

It is worth noting that in different regions of the firmware, this component can be called differently or have a different set of functions. In Chinese versions of MIUI, it is deeply integrated with local services, while in global firmware (Global ROM), its functionality is often reduced to a basic number definition.

⚠️ Note: Removal of system components through ADB Root rights without first creating a backup can cause unstable operation of the communication module. Before interfering with system files, make sure that you have a restore point.

It’s important to understand the difference between a regular directory and this service. If the first one just stores your records, the second one actively uses the Internet connection to check each incoming call, which means that when a call is made from an unknown subscriber, your smartphone sends a request to the servers of the database provider (often Xiaomi partners in a particular region) to get the organization name or the “Spam” tag.

The main functions and capabilities of the service

Yellow Pages goes beyond mere identification, and is a powerful tool for filtering unwanted calls, analyzing behavioral patterns of numbers and complaints from other users, flagging suspicious contacts, especially for telemarketers and scammers who often change SIM cards.

It also offers easy navigation by service category, can quickly find the nearest pizzeria, taxi or pharmacy without opening the browser, grouping organizations into thematic sections, which speeds up the search for the right phone, and some versions of the shell even allow integration with maps to plot a route to the selected point.

Also worth mentioning is the ability to update databases on the fly, so you don’t have to manually download new versions of directories; the service does this automatically when you have Wi-Fi, which ensures that information about new organizations or changed emergency numbers is always up to date.

Impact on data privacy and security

Privacy is the most pressing issue when discussing any services that have access to a phone book. Yellow Pages requires extensive permissions, including access to contacts, call logs and geolocation, which is theoretically necessary for search and identification functions to work properly, but from a digital hygiene perspective, it is a concern for power users.

The data transferred may include not only the numbers you are looking for, but also metadata about your interactions. Although Xiaomi claims to comply with privacy policies and encrypt traffic, the fact that information is transferred to third-party servers remains a fact.

If you're worried about data breaches, it's a good idea to carefully examine permission settings. You can leave access to contacts but deny access to location, although this will limit the search functionality of nearby organizations.

Instructions: How to disable number definition and Yellow Pages

Complete removal of a system application without Root rights is impossible, but it can be effectively disabled, making it impossible to work. The easiest way is to deny access to the network. To do this, go to Settings → Applications → All applications, find in the list of Yellow Pages (or Yellow Pages), and select Data Control.

In the menu that opens, you need to uncheck the "Wi-Fi" and "Mobile Network" boxes, and then the application will remain on the system, but will not be able to send requests to the server to check the numbers, which will "freeze" its functionality, keeping the rest of the system stable.

Additionally, it is recommended to disable notifications from this component so that it does not bother you with promotional offers or blocking reports.In the same menu of the app settings, find the Notifications section and deactivate all switches. This will save the status bar from unnecessary visual noise.

Removal via ADB for advanced users

For those who want to get rid of the com.miui.yellowpage process completely, there is a method using USB debugging and the ADB (Android Debug Bridge) tool, which is safer than deleting through system files, since it does not require superuser rights and makes it easy to return everything back if necessary.

First, you need to activate the developer mode. Go to Settings. → About the phone and seven times quickly click on the version MIUI. Then in the advanced settings, turn on “Debugging by” USB». Connect your smartphone to your computer, install drivers and ADB-platform.

adb shell pm uninstall -k --user 0 com.miui.yellowpage

Executing this command will remove the application for the current user. The system will continue to work normally, but the numbering function will disappear. If in the future you want to restore the component, just run the command adb shell cmd package install-existing com.miui.yellowpage.

⚠️ Attention: When in use ADB Be extremely careful with packet names, removing critical system components (e.g., those associated with a phone or a phone) SMS) This can cause loss of communication (bootloop).

Alternative solutions for numbering

If you don’t like Xiaomi’s standard service, the market offers many alternatives, and a popular solution is to install apps like Truecaller, Yandex (with a determinant), or Kaspersky Who Calls, which often have more spam bases and are better adapted to local markets.

However, installing a third-party detector requires disabling the standard one to avoid conflicts, and usually when installing a new application, the system will prompt you to choose the default one for handling calls.

💡

Use Google Assistant to filter calls. Google’s Phone app has a built-in Call Filter feature that automatically resets spam without installing additional apps.

The choice between an embedded solution and third-party software depends on your priorities: the built-in service is less visible and better integrated into the interface, whereas specialized applications can offer more flexible lock-in scenario settings and a community of users.

Comparison of Opportunities: Built-in Service vs. Analogues

To determine the need for Yellow Pages on your device, let’s compare its key features with popular third-party solutions. The table below shows the main options that affect the selection.

As you can see from the comparison, the built-in solution benefits in energy efficiency, but it can lose in the relevance of databases for specific regions. Third-party applications are often updated more often, but require more device resources.

💡

The best strategy is to disable network access for the built-in Yellow Pages and use Google’s filtering assistant if you don’t need specific Chinese database features.

In conclusion, Xiaomi’s Yellow Pages is not a virus, but a useful but controversial privacy tool that is justified if you’re a delivery and taxi user and want to see their names instead of numbers, but for conservative users who value cleanliness and anonymity, turning it off is a smart move.
