Many Xiaomi, Redmi and POCO smartphone owners are faced with a voice assistant that is triggered accidentally when unlocking the screen or in their pocket, which is not only annoying, but can drain the battery or lead to errors, a problem that is relevant for both the old MIUI shell and the new HyperOS.
Google Assistant is deeply integrated into Android, so you can’t just delete it, but you can completely deactivate it. In this article, we’ll look at all the known ways to disable the assistant on your phone so that it stops responding to voice and buttons.
We will look at the standard system settings, as well as deeper methods through the special features menu, and you can choose the option that will suit your device model and firmware version.
Why does the assistant turn on on its own?
Often users don't understand why Google Assistant is activated without their knowledge, but the main reason is sensor sensitivity and voice recognition settings, and the system is set up to be always ready, waiting for a "OK, Google" command or a long press of the power button.
The second reason may be accidental touch of the screen in a locked state. If the security settings allow the assistant to start from the lock screen, then any careless movement can activate the digital assistant, this is especially true for models with AMOLED screens, where the AOD (Always On Display) function can respond to touch.
⚠️ Attention: Constant activation of the assistant in the background can significantly affect the battery life of your smartphone, as the microphone and the processor constantly monitor the audio stream.
Also, it is worth considering that some applications may request access to voice input, which is sometimes perceived by the system as a call to the main assistant, and understanding the source of the problem will help you choose the right method of solving it.
Disconnection through Google Settings
The safest and most effective way to do this is to use the regular settings menu of Google itself, which allows you to turn off the assistant functionality without affecting the other system components.
In the upper right corner, click on your account avatar. In the menu that opens, select Settings, then go to Google Assistant, and that's where all the AI behavior controls are.
- 📱 Click on Google Assistant in the Settings List.
- 🔌 Find the Google Assistant switch and turn it to the “Off” position".
- 🗣️ Turn off the “OK Google” recognition option if you want to disable voice activation.
- 🔒 Make sure that your current device is not selected in the Devices section to activate.
Once you do this, the system will stop responding to voice commands, but if you have a button setup, this method may not help completely, and you will need to adjust the system settings section.
💡
Disabling in the Google app removes voice response, but doesn't always block startup through the power button or MIUI interface gestures.
Setting up the power button and gestures in MIUI and HyperOS
In Xiaomi shells, it is often the default to assign a power button to an assistant call. To change this, go to Settings on your phone, then select Additional or Advanced Settings. Find Buttons or Buttons and gestures.
Here you will see the option to Start Google Assistant (or Press and Hold Power button) and the default option is Google Assistant. Click on this option and select No or Shutdown menu, which will return the default behavior of the button.
☑️ Checking the settings of the power button
Also, check your gesture settings. In Settings → Lock screen, make sure that any options related to running apps or functions with double-touch or swipe are disabled. This will prevent accidental launches out of your pocket.
If you’re using HyperOS, the path may be slightly different: Settings → Additional Features → Buttons. The interface may look different, but the logic remains the same – you need to reassign the retention action.
Use of special opportunities
There's a more radical method that advanced users often use, which is to turn off the voice assistant access service, which is effective if the standard settings don't work or are reset.
Go to Settings → Advanced Settings → Special Features. In the list of available services, find Google Assistant or Voice Access. If you have one, click on it and turn it off.
⚠️ Warning: Be careful when changing settings in the special features section. Disabling system services may affect other features, such as voice control in navigation.
In some versions of MIUI, this item may be called Accessibility. Inside the menu, find a switch that allows the application to access the screen and turn it off, which will completely prevent the assistant from taking control of the interface.
This is especially useful for those who want to keep Google’s app installed for search, but completely remove its voice functions, creating a balance between functionality and the absence of stimuli.
Comparison of disconnection methods
To make it easier for you to choose the right way, we have prepared a comparison table that will help you understand what method will be most effective in your situation, whether it is a complete lock or just a voice shutdown.
| Method | Efficiency | Difficulty | Impact on the system |
|---|---|---|---|
| Google App Settings | Medium | Low. | Minimum |
| Reassignment of the button | Tall. | Low. | Absent. |
| Special opportunities | Maximum | Medium | Average. |
| ADB team | Complete. | Tall. | High. |
As you can see from the table, for most users, the best solution is a combination of reassigning a button and setting up an app. Methods using ADB (Android Debug Bridge) require a computer connection and command line knowledge, so they are recommended only for advanced users.

Frequent problems and their solution
Sometimes, after updating the firmware MIUI or HyperOS settings can get lost and the assistant starts working again. In this case, check whether the Google application itself has updated in the Play Market store. New versions often return the old settings by default.
Another problem may be conflict with other voice applications, such as Yandex Alice or Bixby (if they were installed earlier).
- 🔄 Perform a reset of the Google app settings: Settings → Annexes → All applications → Google → Clear the data.
- 📵 Check if Safe Mode is activated, which may block certain settings.
- 🔋 Ensure that energy savings do not block system services from running, causing disruptions.
If nothing works, reset your phone to factory settings, but that's a last resort, and 99 percent of the time, you solve the problem by setting the items described above.

Before major system updates, take screenshots of current button settings and special features, which will save time to restore the usual configuration.
