Modern smartphones, including the popular Xiaomi Redmi 9, feature a host of smart features designed to make it easier to interact with the device. However, Google Assistant, while useful, often becomes a source of annoyance for users who accidentally activate it in their pocket or while talking. Constant pop-ups and voice queries can interrupt important actions, requiring immediate intervention in system settings.
Redmi 9 owners running on the MIUI shell face the need for deep tuning, as there is no standard switch to turn off everything in one menu, deactivation requires going through multiple levels of the settings menu of Google and the Android system itself, which is necessary to completely eliminate the background activity of the assistant and prevent it from responding to voice commands.
In this article, we will take a closer look at each step required to completely shut down the service, learn how to disable the response to the phrase “OK, Google”, how to remove the assistant from the lock screen and what alternative management methods are available, and understand these processes will allow you to make using your smartphone more comfortable and controllable.
The main reasons for disconnecting the voice assistant
Many users are wondering why they should even turn off such an advanced tool when it is built into the default system. The main reason is often random activation. A smartphone in a pocket of trousers or bags can perceive friction of fabric or foreign sounds as a command "OK, Google", then begins to perform actions, consume battery and even make calls.
Another factor is privacy: constantly listening to the microphone to wait for a key phrase is a concern for people who monitor their digital privacy. While Google claims that data is secure, the ability to completely shut off access to the microphone for third-party services remains an important security aspect for many Android device owners.
⚠️ Warning: The complete shutdown of Google system components may affect other voice-dependent applications, such as dictating text in instant messengers or navigating in the car.
Also worth mentioning is the impact on autonomy: Background work of the assistant, although optimized, still consumes processor resources and battery power. For low-end devices like the Redmi 9, where every percentage of charge counts, turning off unused features is a smart step to optimize.
Global Disconnection through Google Settings
The most effective way to remove the assistant functionality is to disable it in the root settings of Google, which blocks the basic logic of the program, making it impossible to run it in standard ways, first you need to open the Settings menu of your Redmi 9 and scroll down to Google.
In the menu that opens, select Settings for Google apps, and then search Search and Assistant. That's where all the levers of smart function are concentrated. Click on Google Assistant to go to the detailed configuration. At the top of the screen, you'll see a switch that allows you to stop the service completely.
Once the main switch is turned off, the system can request confirmation of your actions, warning you that some functions will stop working. This is a standard reaction of MIUI and Google services. We agree and check the result: now, with a long press of the home button or saying a key phrase, nothing should happen.
☑️ Checking the shutdown
It's important to understand that this method doesn't remove the app from the device, it just deactivates its functionality. Google Play services will continue to work as normal, running maps, app store and synchronizing contacts. You just remove the voice intermediary between you and the system.
Setting up your voice response and Hotword
If you don't want to shut down completely, but you're annoyed by the constant response to the word "OK," you can fine-tune the microphone sensitivity. In the same Assistant settings menu, find the Ok Google and Voice Match section, and there's a hot-phrase recognition switch.
By disabling the Ok Google option, you will prevent the phone from responding to voice when the screen is off or locked.This solves the problem of random switches out of your pocket.However, if the screen is active and you are in the Google app, the assistant can still be called by voice if you do not turn off adjacent settings.
Xiaomi Redmi 9 owners also need to adjust their voice recognition to a specific user, allowing voice models to be overloaded or all voices to be turned off in the Voice Match menu, which improves security by preventing unauthorized access to your data via voice commands even if the phone is unlocked.
⚠️ Note: After the firmware update MIUI Voice Match settings may reset. We recommend checking this section periodically to make sure that the protection against accidental activation is active.
It's worth noting that the quality of recognition depends on the calibration, and if you decide to go back to the way it was, but the assistant starts to get it wrong, try re-training your voice in a quiet room, which will improve accuracy and reduce the number of false positives in the future.
Why does the assistant turn on himself?
Control via lock screen and buttons
One of the most common causes of discontent is to run the assistant directly from the locked screen. On Redmi 9, this often happens when you swipe in the corner or press the power button for a long time, if such a feature is assigned. To eliminate this, go to Settings → Passwords and Security.
You need to find the partition associated with the lock screen and disable Access to the Assistant or Google Assistant. The path may vary slightly from one version of MIUI, sometimes it is hidden in the Advanced Settings menu, and the main thing is to find a ban on starting services without unlocking.
The power button deserves special attention. In modern MIUI updates, a long press on the power button may not cause the turn off menu, but the Google Assistant, to change this behavior:
- 📱 Go to Settings. → Additionally. → Buttons.
- ⚙️ Find the item Long-term press of the power button.
- 🔌 Select the Off Menu action instead of Google Assistant.
This simple manipulation brings back the logic of physical buttons, so you don't accidentally call a robot when you just want to turn off your phone or reboot it, and this is especially important in stressful situations, when you need a quick response from the device.
💡
Changing the power button is a critical step for users accustomed to the classic Android shutdown menu.
Comparison of deactivation methods
Once you've figured out the individual settings, it's helpful to organize the information. Different disabling methods affect different aspects of how the system works. Below is a table that will help you choose the best configuration for your Redmi 9 use case.
| Method | Impact on the battery | Security | Convenience |
|---|---|---|---|
| Complete shutdown in settings | Maximum savings | Tall. | Low (must be manually included) |
| Turning off Ok Google | Average savings | Medium | High (working on the button) |
| Lock screen ban | Minimum savings | Tall. | High (available after unlocking) |
| Change of action of the power button | No change. | It doesn't. | Maximum (conventional logic) |
As you can see from the table, combining methods yields the best result, such as turning off voice control but leaving the button to call, changing the power key assignment, which provides a balance between functionality and control.
Users who rarely use voice input can safely opt for a complete shutdown, which is guaranteed to eliminate any audio signals and visual notifications associated with Google Assistant, while partial customization is suitable for those who sometimes use search, but want to avoid accidents.
Decision and additional advice
Even after you have done all the settings, there may be nuances, such as the assistant may periodically come to life after updating Google apps, in which case you need to repeat the procedure for checking the settings, and you should also pay attention to third-party launchers, which may have their own voice search settings.
If you are using Mi AI (It's a built-in assistant for Xiaomi, and it can conflict with Google or duplicate its features. → Mi AI You can also turn off voice awakening to avoid confusion, and two active assistants at the same time are guaranteed resource expenditure and conflict.
💡
Use Do Not Disturb at night to rule out any audible notifications from system services, including attempts to activate the assistant.
In some cases, cleaning the data of the Google application helps. Go to Settings → Apps → All apps → Google → Memory and click Clean. This will reset the service settings to factory settings, and you will have to configure again the desired parameters, which often eliminates software glitches.
⚠️ Attention: Google app data cleanup will delete search history saved on the device and reset personalization. Use this method only if other methods have not helped.
Remember, the Android operating system is constantly evolving. Menu interfaces can change with the release of new versions of MIUI. If you do not find an item, search inside the phone settings by entering the keyword "Assistant" or "Google", which is the fastest way to find the current location of the switches.
