Owners of Xiaomi Redmi Note 8 Pro smartphones often face the situation where the device suddenly activates the voice assistant when you remove from your pocket or accidentally press the power button.This can be due to the peculiarities of setting up the MIUI system or pre-installed Google services. Voice input is certainly convenient, but its spontaneous operation irritates many users, especially in quiet places or during meetings.
The solution to this problem requires a comprehensive approach, since several speech recognition systems can be active on the device at once. Depending on the firmware region (Global, CN, EU), the main assistant can be Google Assistant or Xiaomi proprietary development called XiaoAI. To completely protect yourself from unexpected microphone inclusions, you need to check the settings of both services.
In this article, we will discuss all possible deactivation methods in detail, and we will look not only at software disabling through the settings menu, but also at the nuances of working with the physical lock button, you will learn how to prevent the system from running the assistant at a long press and how to clear the accumulated history of requests to improve privacy.
Identification of an Active Voice Assistant
The first step before making any changes to your smartphone configuration is to determine exactly which service responds to your actions. The Redmi Note 8 Pro is most often dominated by the Google ecosystem, but some versions of the shells can be implemented by a manufacturer's assistant, and understanding what we are fighting with will allow you to choose the right algorithm of actions and not waste time on unnecessary manipulation.
Note the interface that pops up on the screen. If you see the characteristic color dots or logo with four colors, it is Google Assistant. If the interface looks more minimalistic or contains Chinese/English inscriptions associated with the MI brand, XiaoAI is active. In rare cases, users can install third-party applications such as Alice or Siri (via emulators), which also require separate customization.
⚠️ Warning: Before disabling system services, make sure you have an alternative way to control your phone if you’re used to using voice commands to dial a number or run apps.
It's also worth checking if the assistant is set to launch for a specific action, such as a swipe from the corner of the screen or on the connection of headphones. Often users do not even suspect that they activated this feature a month ago, and now look for the cause of the "glitch." To diagnose, just say aloud "OK, Google" or press and hold the power button - this will immediately show which module is responding.
Disabling Google Assistant through Settings
The most common scenario is to deactivate the search giant's standard assistant.The setup process on the Redmi Note 8 Pro is quite logical, but requires care, since the menu can be hidden deep in system settings. We'll use the standard path through the Android Settings app.
To start, open the main menu and find the gear icon, and you'll need to go to a section that's usually called Google or Google Services and Preferences, and that's where all the keys to managing the search engine ecosystem installed on your device are located. Find Settings for Google Assistant or simply Assistant in the service list.
☑️ Pre-switch check
Inside the assistant menu, you need to find the Phone or Devices tab if it doesn't open automatically, and there's a master switch that stops the service completely, and once it's turned off, the phone will stop responding to voice commands and pressing the home button for a long time (if it's virtual).
- 🔹 Open Settings and swipe to Google.
- 🔹 Select Settings for Google Apps and find Search and Assistant.
- 🔹 Go to the Google Assistant section and click on the Phone tab.
- 🔹 Transfer the slider to the off position (Off).
It is important to note that after updating the Android operating system or the MIUI shell, these settings can reset to factory values, so if the problem returned by itself after another update, the algorithm of actions remains the same - just repeat the shutdown procedure.
Control of the power button and gestures
One of the most annoying features on the Xiaomi Redmi Note 8 Pro is to launch the voice assistant when you press the screen switch long enough. By default, the system is often configured exactly that way, leading to random activations in your pocket. Fortunately, this behavior can be changed through a special button menu.
You need to go to Settings → Additional settings → Advanced button settings (the path may vary slightly in different versions of MIUI, sometimes it is Special.) Here you will find the option “When pressed for 0.5 seconds” or “Long press”, which is responsible for the response to hold the power button.
Change the action from Google Assistant to Nothing or Shutdown Menu, which is more convenient because it allows you to quickly reboot the device or turn it off without going through the lock screen. If you choose Nothing, then a long press is simply ignored by the system, which completely eliminates accidental start.
| Action. | Standard setting | Recommended setting | The effect |
|---|---|---|---|
| Single tap | Screen locking | Screen locking | No change. |
| Double-push | Camera/Nothing | Nothing. | It excludes accidental camera launch |
| Long press. | Google Assistant | Shutdown menu | Convenient access to reboot |
Also worth checking is the gesture settings. In Settings → Additional settings → Gestures and buttons, make sure that the swipe from the bottom corner of the screen is not assigned to start voice input. This feature is often turned on by default for quick access, but when you carry your phone tightly in your pocket, it becomes a source of problems.
Deactivation of XiaoAI and regional services
If you own a version of a smartphone designed for the Chinese market, or have installed a global firmware with residual traces of regional services, XiaoAI can function on the device. This assistant is deeply integrated into the system and sometimes conflicts with Google services, causing double positives.
To manage this component, you'll need to find the XiaoAI app or log in to the settings through your Mi Account account. In the profile menu, find the section associated with the voice assistant, and it's important not just to turn off the microphone, but to deactivate the voice function.
⚠️ Note: Disabling XiaoAI system components on global firmware may cause some system applications that depend on libraries to run unstablely. MIUI.
In some cases, you can't completely remove or disable XiaoAI without getting a Root license. However, you can limit its activity. Go to Settings → Applications → All Apps, find XiaoAI and select Stop or Disable. If the button is inactive, try selecting permissions to use the microphone in the Permissions section.
Risks of removing system components
Also check the language settings. If multiple input languages are selected, the assistant may become confused and activated when recognizing phonetically similar words in different languages, and leave only the primary interface language in the keyboard and voice input settings.
Setting up alarm clocks and triggers
A common reason for voice switching on is smart alarm settings or automation scenarios. Redmi Note 8 Pro has a feature that allows the alarm clock to voice the weather or news immediately after the signal is turned off, and this is done through the same voice engine that triggers it.
To remove this trigger, open the standard Watch app. Go to the settings of a specific alarm clock (usually through an arrow or gear next to the time), find the option "Voice" or "News after the alarm clock" and turn it off. Now the alarm clock will just ring and vibrate, without triggering heavy network processes.
- 🔹 Open the Clock app on the desktop.
- 🔹 Click on three dots or a gear in the corner of the screen.
- 🔹 Find the section Voice alarm clock or scripts.
- 🔹 Disable all items related to Google Assistant or News Feed.
Also, check the Mi Remote app or Scenarios. If you've ever set up the "When I Come Home, Turn on the Lights" automation, it could activate the voice module to confirm the action. Deleting or editing such scenarios will also help reduce the frequency of unwanted launches.
Clearing History and Resetting Voice Settings
Even after all features are turned off, it is recommended to conduct a “digital cleanup”; voice assistants store your request history on servers and in the device memory to improve recognition. On the Redmi Note 8 Pro, this data takes up space and may contain confidential information.
To clear your Assistant's Google history, go to myactivity.google.com in your browser or through your Google account settings on your phone. Select the Audio filter and delete all data. This action will break the link between your voice and your profile, which is especially important if you're selling the phone or transferring it to another user.
💡
Periodic cleaning of the cache of the Google app (Settings → Apps → Google → Memory → Clear cache) helps eliminate recognition errors and prevents phantom assistant launches.
If the problem is software-based and the assistant turns on on itself even after all the settings, reset the app. Go to Settings → Apps → All Apps → Google → Memory and click Clear All Data. This will return the voice module to a “like after-purchase” state, killing all possible configuration software bugs.
In the extreme case, if nothing works, you can use Safe Boot mode. Press the off button, and when the menu appears, press and hold your finger on Turn off until you prompt to go to Safe Mode. If this mode does not enable, then some third-party application that you installed recently is to blame.
