Google Assistant on Xiaomi smartphones can suddenly stop responding to commands, not open by voice or disappear altogether. The problem is relevant for devices on MIUI of all versions - from budget Redmi to flagship Xiaomi 13/14. Most often, the failure occurs after updating the firmware, resetting settings or installing third-party applications.
In this article, we’ll break down 10 key reasons why Google Assistant doesn’t work for Xiaomi, from the banal lack of internet to deep conflicts with Google Play services. ADB, cache cleaning and manual installation APK. We will pay special attention to the problems of Chinese firmware (Global) ROM vs China ROM) Devices without Google Mobile Services certification (GMS).
If your Xiaomi doesn’t respond to “OK Google,” doesn’t open the Home button retention assistant, or if it says “Google Assistant is not supported on your device,” you’ll find a solution here. Start with the simplest checks and gradually move on to complex technical manipulations.
1. Check the basic working conditions of Google Assistant
Before digging deep into the system settings, make sure the minimum requirements for the assistant work are met. Often the problem lies in the little things that users miss:
- 🌍 Region and language: Google Assistant does not officially support all countries. If the smartphone settings indicate the region where the service is blocked (for example, China, Iran), the assistant will not start. → Additionally. → Language and input → Region.
- 📶 Internet connection: The assistant requires stable network access. Even if you have mobile internet, some features (such as voice input) may not work without Wi-Fi.
- 🔊 Microphone and speakers: If your smartphone doesn't recognize voice commands, check if the microphone is silenced (for example, after falling or getting moisture.
- 🔋 Energy conservation: MIUI If Google Assistant is disabled from auto-start or added to the list of “deep cleaning”, it will not work in the background.
Pay special attention to date and time settings. If they are downed or manually set (not the Network provides), Google services may block access to the assistant due to time stamps mismatch with the servers. Correct this to Settings → System → Date and time.
2. conflict with Google services: GMS and lack of certification
The most common reason for Google Assistant’s failure on Xiaomi is a problem with Google Mobile Services (GMS).
- 📦 Devices on Chinese firmware (China) ROM): They initially ship without Google services. Even if you manually installed Google Play, the Assistant may not work due to lack of certification.
To check the status of the GMS:
- Open the Google Play Store.
- Go to Settings. → About the programme.
- Scroll down to the Device Certification section, and if it says "Uncertified," the assistant won't work.
Decisions:
- 🔧 Installation GMS manually (for China) ROM): Download the Google Installer package (e.g. with APKMirror) and follow the instructions.Watch out: on new models (e.g. Xiaomi) 13T) This method may not work due to blocking. MIUI.
- 🔄 Reflashing on Global ROM: It's a radical but reliable way. XDA Developers or 4PDA.
⚠️ Attention: Installation GMS Uncertified devices may result in a Google account being blocked or payment problems in the Play Store.
How to check the firmware version on Xiaomi?
Mistakes in MIUI settings: Autostart and permissions
MIUI is known for its battery-care, which often interferes with the background applications. Google Assistant can be disabled from auto-start or denied the necessary permissions.
- Autorun: Go to Settings → Apps → App Management → Google (or Google Assistant). Tap on Autorun and turn on the option. Do the same for Google Play Services.

- Open the Settings. → The phone.
- Tap 7 times on the MIUI version line to activate the developer mode.
- Back to Settings → Additionally. → For developers.
- Find the option “Disable the restrictions for assistants” (or similar) and turn it on.

6.Manual recovery via ADB (for power users)
If all previous methods have failed and Google Assistant is still not responding, you can try force activating it via ADB. This method is suitable for devices where the assistant is installed but not launched due to MIUI limitations.

- Enter the command to check the connection: adb devices If the device is displayed, go further.
- Follow the command to activate Google Assistant as default assistant: adb shell cmd assistant set-default-assistant com.google.android.googlequicksearchbox/.GoogleAssistant
- Reboot the phone.
If the assistant still does not work after that, try resetting it via ADB:
adb shell pm clear com.google.android.googlequicksearchboxSome Xiaomi models (such as the POCO F4 or Redmi K50) require manually running Google Assistant through the search bar after performing these commands so that it reappears in gesture settings.
💡
Using ADB is a last resort, and if you are not sure about your actions, it is better to seek help from profile forums or a service center.
7. Alternative ways to run Google Assistant
If standard methods don’t work, you can try workarounds to call an assistant:
- 🔍 Through search: Open Google Search (widget or app) and tap on the microphone icon. This will cause the Assistant to bypass system constraints.
- 📱 Home screen shortcut: Add a shortcut to the home screen for Google Assistant via the widget menu.
- 🎧 Through headphones: Some Xiaomi models (like the Xiaomi 13 Pro) allow you to call the assistant with a long press on the headphone button.
- 🤖 Third-party launchers: Install an alternative launcher (like Nova Launcher or Action Launcher) where you can customize your gesture to call an Assistant.
If you want voice activation (OK, Google) but it doesn’t work, try retraining your voice model.
- Open Google Assistant (via search bar or shortcut).
- Slip on the profile icon → “Settings” → “Voice Match”.
- Remove the old voice model and write down a new one.
