Accessibility Service on Xiaomi: Search, Configuration and Hidden Features

Owners of Xiaomi, Redmi and Poco smartphones often face a mysterious notification or menu item called Accessibility Service. Many users are frightened to see security warnings that the app is requesting access to screen data and do not know whether to allow this action. In fact, it is the standard Android system mechanism that allows applications to interact with the interface, but in the ecosystem of MIUI and HyperOS, it has its own peculiarities.

Finding this feature may not be obvious, as manufacturers often hide deep settings in the bowels of menus to keep inexperienced users from random changes. But this is where the keys to managing automation, disabling intrusive advertising in system applications, and activating features for people with disabilities lie. Understanding how accessibility works gives you complete control of the device.

In this detailed guide, we’ll look at exactly where this section is on Xiaomi’s modern shells, how the system service differs from third-party apps, and what risks really exist.You’ll learn how to safely manage permissions to improve the user experience without exposing the device to threats.

What is Accessibility Service in Android and MIUI

Accessibility Service is a special API (app programming interface) on the Android operating system, designed originally to help people with disabilities. It allows software to read the contents of the screen, track user actions and even emulate button clicks. In the context of Xiaomi smartphones, this tool is used not only for accessibility functions, but also for the operation of many useful utilities.

When you install an application that requires screen control (such as for automatic clickers, voice assistants, or ad blockers), it cannot simply obtain such rights.The system requires the user to manually activate the corresponding service in the accessibility menu.This is a security mechanism that prevents the hidden installation of malware that could steal passwords entered on the keyboard.

It is important to distinguish between system and third-party services. The availability list can display both the system components of MIUI and the programs you install. System services are safe and necessary for the phone to work, while third-party services require careful study before activation. Understanding this difference is critical to the security of your data.

⚠️ Warning: Never turn on the availability service for applications downloaded from unverified sources or sent as APK-Attackers often use this legitimate tool to intercept codes from SMS and access banking applications.

Where to find the accessibility menu: step-by-step instructions

The settings may vary slightly depending on the shell version (MIUI 12, 13, 14 or new HyperOS) and the Android version. However, the overall algorithm of actions remains the same for all devices of the brand.

First, open the main settings menu of your smartphone. This is usually a gear icon. Scroll down to the "Additional Settings" section (in some versions it may simply be called "Advanced Settings"), and this is where developer tools and special features are concentrated.

In the list that opens, look for "Special Features" (or "Special Features"). Inside this menu, there will be a few tabs or sections. You're interested in the "Services" or "Availability Services" tab, and you click on it and you'll see a complete list of all the applications that have the right to request access to the interface.

If you can’t find an item on the menu, use the search by settings: enter the word “accessibility” or “accessibility” in the search bar, and the system will offer the desired section.

An alternative and faster way to get to the menu is to use the search bar in the settings themselves. Just type in the accessibility request or availability, and the phone will immediately give you a direct path to the service management section, which is especially useful if the menu items have been renamed when localized.

Set up system accessibility functions for the visually impaired

The main purpose of the section is to help users with visual, hearing or motor impairments. Xiaomi implements a number of useful tools in its shells that are activated through this interface.

One of the most useful features is TalkBack, a voice-over that speaks all the actions you do on the screen, which is an indispensable tool for visually impaired users, and Magnification, which allows you to quickly scale part of the screen with triple tap, and color inversion to reduce eye strain in the dark.

• 🔊 TalkBack: Voice over interface elements and user actions with a voice synthesizer.
• 🔍 Enlargement: Virtual magnifier for detailed consideration of small elements on the screen.
• 🎨 Color correction: Change the color scheme for people with color blindness or for comfortable reading.
• 🗣️ Voice control: Executing commands without touching the screen, only with voice.

Activation of these features requires confirmation. The system will warn you several times that the service will see everything that is displayed on the screen. This is standard procedure, and for Xiaomi system components it is safe. Once activated, you can adjust the sensitivity, speech speed and control gestures in the appropriate submenu.

Managing Third-Party Applications and Permits

The most common reason that ordinary users are looking for Accessibility Service is to grant permissions to a third-party application, which can be launchers, screen recording software, action automatizers (macros) or ad blockers, without inclusion in this menu, such applications simply will not work.

The activation process always looks the same: you open the application, it throws you into the system accessibility menu, where the switch is on opposite the program name, you need to move it to the "On" position and confirm the action in the pop-up window, only then the application will receive the necessary permissions.

But be careful. Some applications may request redundant rights, for example, a simple flashlight or calculator should not have access to the accessibility service. If you see such a request, it's a red flag. Always analyze whether the functionality of the program requires such deep implementation into the system.

⚠️ Note: If after installing a new application you began to spontaneously open your browser, appear ads on the desktop or disappear money from the card – immediately disable access to this application in the menu “Availability Services” and delete it.

To manage services that are already activated, you can go back to the settings menu at any time, and you can force the service to stop or completely disable it, and this is a useful skill for diagnosing problems: if the phone starts to glitches, try turning off all third-party availability services and check the system.

Use of the service to disable advertising in MIUI

One of the most popular cases of using Accessibility Service on Xiaomi phones is combating system advertising. Since the built-in MSA (MIUI System Ads) ad module is a system application, you can not simply uninstall it. However, there are special scripts and assistant applications that use the accessibility service to automatically close advertising windows.

The essence of the method is that a special application (for example, various modifications of "AdGuard" or specialized scripts for Termux) receives the rights to read the screen. When an advertising window appears, the program instantly recognizes it and emulates the click of the "Close" or "Skip" button. To the user, this looks like the instantaneous disappearance of the ad.

This method often requires not only enabling the service, but also providing the application with additional permissions through ADB (Android Debug Bridge), a more advanced level of customization that allows scripts to run more stable. Below is a table with the main components that often require accessibility management to block ads.

Diagnosis of problems and frequent errors

Despite their usefulness, accessibility services can be a source of problems, sometimes when you update your MIUI or HyperOS firmware, settings get confused or services start to conflict with each other, which can manifest as interface freezes, spontaneous menu transitions, or increased battery consumption.

If you notice that the phone is acting strangely, the first thing you do is check the list of active services. Often times, the user has installed the app, given it permission, forgotten about it, and it continues to work in the background and consume resources. Deleting such an application will automatically turn off its service, but it is better to check the list manually.

• 🔋 Battery discharge: Constant screen survey by the availability service can significantly reduce the time of operation.
• 📉 Interface Brake: Conflict between two apps trying to control the screen at the same time.
• 🔒 Blocking Entry: Some services may intercept touches, interfering with normal typing.
• 🔄 Cyclical reboots: In rare cases, a faulty service can take the system to a bootloop.

To fix problems, try clearing the cache of a problem app or resetting special features. In extreme cases, if the phone does not boot due to a conflicting service, you may need to log in to Safe Mode, where third-party services are not activated, which will remove the culprit.
