The Xiaomi Mi A2 Lite, part of the Android One program, offers a clean operating system without unnecessary add-ons, which is its undoubted advantage. However, many owners face the intrusiveness of the built-in Google Assistant, which can be activated accidentally when unlocking the device or by voice command. This often leads to inconvenience, especially if you are used to using other management methods or simply do not need to constantly listen to the environment.
Disabling this feature completely requires several sequential actions in the system settings, since there is no single “Switch Off All” button in the interface. In this article, we will detail every step necessary to deactivate voice control, remove the call button and disable activation by saying “OK, Google.” On Android One (Mi A2 Lite), the assistant settings are deeper than in the MIUI shell, and require you to go through the search engine menu.
Before we make any changes, it's worth noting that the rejection of voice assistant can have a positive impact on the battery life of your gadget. Background processes responsible for speech recognition and waiting for a trigger phrase consume the resources of the processor and microphone. Let's take a detailed look at the algorithm of actions to completely shut down the service.
⚠️ Note: Before making changes to your system settings, make sure you understand exactly what features you are disabling, as this may affect navigation and search usability.
Access to Google Assistant settings
The first step to deactivation is to log into the deep settings menu of the service itself, not just a shortcut on the desktop. Unlike standard apps, the assistant configuration is hidden within the general settings menu of your Google account, you need to open any Google application or just swipe the assistant from the corner of the screen to get to the desired menu.
When you call the interface, look for your profile avatar or settings icon, which is usually located in the top right or bottom corner of the screen, and clicking on it, you'll be taken to the menu where you want to select Settings, and then find the Google Assistant section, and that's where all the levers of behavior control of the intelligent assistant are concentrated.
The settings interface may seem overloaded, but we're interested in a specific tab called "All Assist Settings" or similar, which gives you access to device management. It's important not to confuse Google search settings with the settings of the voice module itself. Proper navigation through the menu is the key to success.
- 📱 Open the Google app or call the assistant swipe.
- ⚙️ Click on the profile icon or settings in the corner of the screen.
- 🔍 Select Settings and go to Google Assistant".
- 📂 Find the tab "All Assist settings" for detailed management.
Disabling activation by voice and lock screen
The most important setting for many users is to prevent the assistant from activating without touching the screen. By default, the system is set to constantly listen to the phrase "OK, Google", which is convenient on the one hand, but on the other hand, consumes battery and invades privacy. To turn this feature off, you need to find the "Hey Google and Voice Match" section in the Assistant settings menu.
Inside this section, you'll see a voice-command-response switch, which you'll see in the off position, you'll stop the phone from responding to your voice, and you'll also often hide the lock-screen activation option, and the device's security will increase, because outsiders won't be able to access information through voice requests while the phone is locked on the table.
It is also worth checking the settings for "Results on locked device." Even if you do not turn off the assistant completely, restricting access to personal information from a switched-off screen is a good practice, which will prevent data from leaking from the calendar or messages when accidentally activated in your pocket.
⚠️ Note: After disabling voice activation, the phrase “OK, Google” will stop working even when the screen is unlocked, unless you manually change the settings in the same menu.
Remember, the changes are instant. You can check the result by just saying the key phrase. If the phone is silent, the settings are correct. This is especially true for the Mi A2 Lite, which has a compact body and sensitive microphones.
Why can the assistant activate itself?
Managing the power button and labels
The Android One lineup, which includes the Xiaomi Mi A2 Lite, often features a long-press power button to call the assistant, which can be extremely inconvenient if you’re used to using long-pressing to turn off your phone or call the emergency services menu. Fortunately, this feature can be reconfigured or disabled.
To do this, go to your smartphone's basic Settings, scroll down to System and select Languages and Enter. There may be a separate "Power key" or "Additional settings." In some firmware versions, this is in Gestures. You need to find the option "Long-Tap Power button" and change the action from "Google Assistant" to "Switch off me" or "Nothing."
If standard system tools fail to change the behavior of the button, you can use third-party utilities to reassign the buttons, but on Android One with its strict security policy, this may require additional permissions.
| Action. | The way is on the menu | Recommended value |
|---|---|---|
| Long pressing | System → Gestures | Shutdown menu |
| Double-push | System → Gestures | Camera (default) |
| Swipe from the corner | Google settings | Shut down. |
| Voice activation | Assistant → Hey Google | Off |
💡
If the power button still calls the assistant, try clearing the Google app cache through the Apps menu in your phone's settings.
Setting up the sidebar and widgets
Another source of random launches can be a sidebar or widgets on the home screen. In the clean version of Android installed on the Mi A2 Lite, the Google widget is often placed at the top of the screen or on a separate page on the left. Although it is not always possible to completely remove the system widget without root rights, it can be replaced or hidden.
Press your finger on an empty desktop space to enter edit mode. Find the Google widget and click on it to see the options available. Often there's a Show Detect switch or the ability to resize the widget by removing the microphone button. Reducing the widget to a simple search bar will save you the risk of accidental touch.
It's also worth checking the Google Discover settings, which swipe to the right, and in this section, you can turn off the card display and, in some cases, the voice input button, leaving only text search, which will make the interface cleaner and minimize the chance of random voice search activation.
- 🏠 Click the empty space on the desktop for editing.
- 📉 Click on the Google widget and select the minimum size.
- 🚫 In the widget settings, turn off the microphone display.
- 📲 Check the left page (Google Discover) for active buttons.
Limitation of background activity and permissions
If your goal is not just to remove buttons, but to limit the service as much as possible in the background to save charge, it is worth turning to managing application permissions. Android provides flexible tools to control what the Google app can do. Go to Settings → Apps and notifications → Show all apps.
Find the Google app (not Chrome, but Google's system app) in the list. Go to the Permissions section. Here you are interested in the Microphone item. If you turn off microphone access, voice input and word activation will become physically impossible, but it will also disable keyboard dictation and voice search in Chrome.
A softer option is to limit background activity. From the battery menu for the Google app, select "Saving Charge" or "Limited" mode, which will keep the service from constantly hanging in memory and listening to the environment, only launching when you explicitly open the app, which is an effective way to combat battery drain on the Mi A2 Lite.
⚠️ Warning: Disabling the microphone for the Google app may disrupt the voice recorder, voice input in the Gboard keyboard and other dependent services.
☑️ Checking restrictions
Use of third-party launchers (Alternative)
A radical but very effective way to get rid of the intrusiveness of standard Google services is to install a third-party launcher. The standard shell of Android One is quite minimalistic, but launchers like Nova Launcher, Lawnchair or Microsoft Launcher give you complete control over the interface, allowing you to completely ignore the standard search widget or replace it with an alternative.
With a third-party launcher, you can set the search button to launch any other application or disable it altogether. In addition, many launchers allow you to reassign gestures, such as swipe up or sideways, so that they do not call Google Assistant, but open the application menu or other desired feature, which gives the user the Xiaomi Mi A2 Lite maximum flexibility.
It is worth considering that third-party launchers consume their own resources, although modern optimized versions work very quickly. For devices with a storage capacity of 3-4 GB, as in the case of the Lite version, it is better to choose light launchers that are not overloaded with animation.
💡
Third-party launcher is the only way to completely change the logic of buttons and gestures at the interface level, bypassing the system limitations of Android One.
