How to Disable Google Assistant on Xiaomi Mi9 Forever: From Simple Ways to Deep System Cleanup

Google’s Voice Assistant on Xiaomi Mi9 can be annoying with constant notifications, random activations, or just taking over system resources, especially for users who prefer MIUI-built features or alternative assistants like Alice from Yandex. But simply turning off through the settings often fails to produce the desired result – the service continues to work in the background, consuming the battery and collecting data.

In this article, we’ll look at all the basics to radicals, including ADB deletion and system file modifications. It’s important to understand that some methods require unlocking the bootloader and can affect the stability of the Mi9. If you’re not ready for experiments, look at the first two sections with secure solutions.

Also note that after Google Assistant is completely removed, some features (such as voice search in Google App or integration with smart devices) may stop working.

1. Disconnect via MIUI settings (no root)

The easiest and safest method is to deactivate the Assistant through standard menus, which does not remove the Google Assistant completely, but stops its background and notifications.

Go to: Settings → Google → Settings for Google apps → Search, Assistant and Voice → Google Assistant Settings

Here, select the Assistant tab and scroll to the Devices section. Find your Xiaomi Mi9 in the list and turn off the slider next to it.

It is further recommended that:

• 🔍 Prohibit Autostart: Settings → Annexes → Application management → Google → Autostart (disable).
• 📵 Limit background activity: In the same Google app menu, select “Limit background activity".
• 🚫 Delete data: Settings → Annexes → Google → Warehouse → Clear the data (this will reset the assistant settings).

⚠️ Note: This method does not physically remove Google Assistant – it will remain in the system and can be activated again after Google Play Services updates.

2.Removal of Google App Updates

Google Assistant is built into Google's app (formerly Google Search), which rolls back to the factory version, and some of the assistant's features will stop working, a method that doesn't require root, but can affect browser searches and other Google services.

Instructions:

1. Open Settings → Applications → Application Management.
2. Find the Google app (an icon with the letter "G" on a color background).
3. Slip on the three dots in the top right corner and select "Delete Updates".
4. Confirm the action and restart the Mi9.

After that:

• ✅ Voice activation on the command “OK, Google” will stop working.
• ✅ Notifications from the assistant will disappear.
• ❌ Searching in Chrome browser may be slower.
• ❌ Some widgets (such as the weather on the home screen) may disappear.

⚠️ Attention: Google Play Store will automatically try to update the Google app back.To avoid this, disable auto-update for it: Play Store → Profile → Application management → Google → Turn off auto-update.

💡

If after rolling back updates, Google App stopped opening, clear its cache in the application settings. This will return to work without restoring the assistant.

3. Disconnect via ADB (no root, but with PC)

For users willing to connect the Xiaomi Mi9 to a computer, there is a more radical way to disable Google Assistant via ADB (Android Debug Bridge), a method that does not require superuser rights, but requires debugging over USB and installing drivers.

Step-by-step:

1. Turn on the developer mode on Mi9: Settings → About Phone → MIUI version (stamp 7 times in a row).
2. Return to Settings → Additional → For developers and activate “Debugging by USB”.
3. Connect your phone to your PC and confirm your trust in your computer on the Mi9 screen.
4. Download ADB Tools and unpack into any folder.
5. Open the command prompt (Win + R → cmd) and go to the folder with ADB:

cd C:\path\k\folder\c\adb


adb devices

If the device appears in the list, enter the command to disable Google Assistant:

adb shell pm uninstall -k --user 0 com.google.android.googlequicksearchbox

This command removes the Google app (along with the assistant) only for the current user, without affecting system files.

• ✅ Google Assistant will disappear from the interface.
• ✅ Notifications and background processes will stop coming.
• ❌ The search bar on the home screen will not work (if it was from Google).
• ❌ Some apps (such as Google Photos) may be making errors.

⚠️ Attention: If you reset the settings Mi9 Before the factory, Google Assistant will come back. To avoid this, repeat the command before the reset. ADB or use the methods in the following sections.

4. Removal of system APKs (root required)

If you have a bootloader unlocked and you have Magisk or another root manager installed, you can physically delete Google Assistant files from the system. This is the most reliable way, but it requires caution - an error can lead to a bootloop.

Required files for deletion:

For removal:

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Follow the paths and remove them. APK-files (pre-restore them!).
3. Clear the folders /data/data/com.google.android.googlequicksearchbox and /data/data/com.google.android.velvet.
4. Reboot the Mi9.

⚠️ Attention: Removal PrebuiltGmsCore.apk This will cause the Google Play Store, Gmail and other services to fail. Do not delete this file unless you are prepared for the consequences!

Once the Google APK is completely removed, the Assistant will not return even after resetting, but some apps (such as YouTube or Google Maps) may not work properly.

5. Google Assistant Alternatives to Xiaomi Mi9

If you have disabled Google Assistant but want to keep voice control functionality, consider alternatives:

Built-in solutions from Xiaomi:

• 🎤 Xiao AI — Chinese voice assistant (only for the China region).
• 🔍 Search MIUI — Quick search by phone (called swipe down on the home screen).

Third-party annexes:

For the installation of alternatives:

1. Download the app from Google Play or APKMirror (e.g. Yandex Alice).
2. Set up voice activation in the application settings.
3. If necessary, assign a dedicated button (such as a long press on the home button).

⚠️ Warning: Some alternative assistants (like Alice) also collect data about your queries. If privacy is critical, use offline solutions like Tasker to create your own voice commands.

💡

Before installing a third-party assistant, check its compatibility with MIUI. Some applications (such as Bixby) require additional patches to work on Xiaomi.

6. Risks and consequences of complete removal

Before you get rid of Google Assistant forever, consider the following:

Technical implications:

• 🔋 Increased battery life (5-15%) due to the stop of background processes.
• 🔍 Voice search in Chrome and Google App.
• 📱 Errors in applications dependent on Google Play Services (e.g., Google Play Services, Pokémon GO or Google Pay).
• 🔄 Problems with security updates (if system updates are removed) APK).

Legal and ethical aspects:

• 📜 Violation of Google’s license agreement (although in practice it is not prosecuted).
• 🛡️ Loss of warranty if root or bootloader unlocking was used to remove.
• 🔒 Malware vulnerability (if Google security updates are disabled).

If you use Mi9 for enterprise services (such as G Suite), deleting Google Assistant altogether may result in your account being blocked due to a security breach.

The only way to get it back is to flash the phone through Fastboot with the official MIUI firmware. Backups via TWRP may not restore the system applications correctly.
