Owners of modern Smart TVs often face intrusive integrated services that can interfere with the comfortable viewing of content. In particular, users of the Xiaomi Mi TV 4S model often wonder how to deactivate the built-in Google Assistant, which is activated when you press a separate button on the remote control, This is especially true for those who prefer to use third-party solutions or simply do not want the TV to react to random clicks.
Complete software disabling of the Android TV system component without using sophisticated methods such as root rights is technically impossible because of the operating system architecture. However, there are a number of effective methods to minimize the impact of the voice assistant on your user experience. We will look at both standard settings and more advanced ways to limit functionality through ADB.
It’s important to understand that the Android TV interface is deeply integrated with Google services, so any changes need to be careful. Incorrectly configured can lead to unstable work of some applications that depend on voice input. Below are proven ways to solve this problem that will help you regain full control of the device.
Features of the work of Google Assistant on the Android TV platform
The operating system installed on Xiaomi Mi TV 4S is based on the Android platform, where voice search is a system function, not just a separate application.This means that it has deep access rights and runs at the interface core level. When you press a special button on the remote, the system interrupts current processes and goes into voice command standby mode, which can be annoying when you actively use other functions.
The main problem is that the standard settings menu does not provide a direct “Switch Off Forever” option. Google Assistant is positioned by developers as a key element of the smart home ecosystem.However, users can limit its activity by changing privacy settings and activation methods.
⚠️ Warning: Attempts to remove voice system packs without proper qualifications can lead to a “bricking” of the TV or a cyclical reboot.
It's worth noting that across regions, firmware may have different menu locations, and on global versions of MIUI for TV, the interface may be different from Chinese, so it's important to carefully check the names of the items described in the manual against what you see on your device's screen.
💡
If the voice assistant button is located separately from the navigation keys, the risk of accidental activation is much lower than on remotes, where it is combined with the home button.
Basic settings through the TV system menu
The first step to limiting the functionality of the voice assistant is to carefully check the standard settings of the TV, and although you can not find a complete shutdown here, you can prevent the assistant from listening to the microphone or responding to certain triggers, you need to go to Settings, then select Accounts and login or Google.
Inside the Google menu, find a subsection associated with Google Assistant, where you often have the option to disable voice activity history, and if you don't allow the user to save requests and use the microphone for constant listening, the assistant will become less "smart" but will continue to work on demand, a compromise for those who fear for their privacy.
It's also worth checking your language settings. If you change the main language to one that's not supported by voice input in your area, the assistant may stop responding to commands correctly. It's a crutch, but it works in some versions of Xiaomi firmware.
- 🔹 Go to Settings. → Devices and preferences → Google Assistant for Accessing Key Parameters.
- 🔹 Turn off the “Hey Google” or “Ok Google” option to stop the TV from responding to voice commands without pressing a button.
- 🔹 In the Privacy section, prohibit the use of voice data to improve the service.
☑️ Checking privacy settings
Using third-party apps to reassign buttons
A more effective way to combat an intrusive assistant is to use specialized remapper applications, programs like Button Mapper or Key Mapper that can intercept signals from remote buttons and reassign them to other actions, and that's the perfect way to turn a useless button into a useful tool.
Once installed on the Xiaomi Mi TV 4S, you will need to grant it special permissions through the Accessibility menu. Without this system permission, the app will not be able to intercept the pressing of the hardware buttons of the remote.
With Button Mapper, you can assign a specific application to the voice search button, such as YouTube or a media player, or you can do a "None" action, which effectively blocks the button, and this software solution does not affect system files and is safe to guarantee the device.
| Annex | Type of license | Difficulty setting up | Efficiency |
|---|---|---|---|
| Button Mapper | Freemium | Low. | Tall. |
| Key Mapper | Open Source | Medium | Very high. |
| TV App Repo | Free of charge. | Tall. | Medium |
⚠️ Note: Some versions of Xiaomi firmware can block the operation of the button reappers at the system level. ADB.

Disconnecting via ADB (for advanced users)
For those who are not afraid of the command line, there is a radical method of disabling system components through Android Debug Bridge (ADB).This method allows you to actually "freeze" the package responsible for the Google Assistant, making it invisible to the system. You will need a computer connected to the same Wi-Fi network as the Xiaomi Mi TV 4S.
First, you need to activate the developer mode on the TV. Go to Settings. → About the device and seven times click on the item "Build number", then in the settings menu will appear a new section "For developers", where you need to enable debugging on the device. USB (ADB). Remember. IP-TV address that is displayed in network settings.
Install the platform on your computer. SDK Google Platform Tools. Open the command line and enter the connection command: adb connect IP_Once the connection is successful, you can use the command to disable the packet. Be very careful: disabling the wrong system services can disrupt the TV.
adb shell pm disable-user --user 0 com.google.android.apps.chromecast.appThe above command is an example, but for a voice assistant, the package is usually called com.google.android.googlequicksearchbox or otherwise.The exact name of the package depends on the version of Android TV. It is recommended to back up the settings before executing the command.
- 🔹 Make sure your computer and TV are on the same subnet.
- 🔹 Use the adb device command to check the connection status before entering commands.
- 🔹 To return the functionality, use the command adb shell pm enable.
💡
The ADB method allows you to completely hide system components, but requires a PC and basic command line knowledge.
Alternative remotes and control from a smartphone
If software methods seem too complex or risky, you can go the physical way.Using a universal remote control that supports an IR port or Bluetooth will allow you to avoid using Xiaomi's regular remote at all.Many universal remotes have programmable buttons that can be customized ignoring unnecessary features of the original device.
Another convenient option is to control your TV via your smartphone: the official Google Home or Mi Remote app allows you to fully control your TV from your phone screen, in which case the voice search button on the physical remote simply ceases to be necessary, since you can use voice input directly on your smartphone if you need it.
When choosing a universal remote, pay attention to Bluetooth protocol support, as some navigation features in the Android TV menu may not work properly through the IR port. In addition, Bluetooth remotes do not require line of sight, which increases the comfort of use.
⚠️ Note: When using third-party remotes, the “shut down TV” function may not work correctly, requiring separate code settings.
Some users also use physical locking on the remote, which is a last resort, but it ensures that the assistant never turns on accidentally, and you can gently remove the button cap or put a small piece of plastic under it to prevent the contacts from closing.
Possible problems and ways to solve them
Users may encounter various difficulties during the setup process, such as re-setting the re-apper settings after updating the Xiaomi Mi TV 4S firmware, and access via ADB can be closed. Android TV security periodically checks the integrity of system packages and can automatically reactivate disabled services.
If other functions, such as YouTube search or text entry, have stopped working after voice search has been disabled, you have disabled the assistant-dependent component, in which case you need to reset or reactivate the package via ADB. Always check if the change affects the operation of mission-critical applications.
A common problem is to desynchronize the remote after installing new button management apps. If the remote stops responding, try removing the batteries for 10-15 seconds or reconnecting the Bluetooth connection via the accessory settings menu.
- 🔹 If there are failures in the interface, clean the cache of the application "Settings».
- 🔹 If the TV starts to brake after installing the remappers, remove them and check the system for conflicts.
- 🔹 Always have the original remote for emergency menu access restoration on hand.
