How to make Google a voice assistant on Xiaomi: full instructions

Owners of Xiaomi, Redmi and POCO smartphones often face intrusive behavior from the built-in Mi Assistant, which is activated when you press the power button for a long time. This annoys those who are used to the functionality and accuracy of speech recognition from Google Assistant. Fortunately, MIUI and the new HyperOS system allow you to reassign this feature, turning the standard button into a gateway to the powerful tools of the search giant.

The replacement process does not require root rights or complex device flashing. All the necessary settings are hidden in the system menu or require the installation of a minimum amount of third-party software from trusted sources. In this article, we will discuss in detail how to completely abandon the Xiaomi service and make Google Assistant the main way to manage a smartphone.

It's worth noting that the layout of the items may vary slightly across the shells, but the logic of the actions remains the same for all the models of the brand. Properly configured, you can call the assistant by voice, via a button or by swipe, providing a seamless experience of using the device. Let's look at the available activation methods and their features.

Basic setting of Google Assistant on the device

Before you reassign physical buttons, you need to make sure that the Google Assistant service itself is properly configured and activated in the system. By default, it may be disabled or not have access to the microphone, which will make further manipulations meaningless. Open the Google app on your smartphone and log in to your account.

In the upper right corner, click on the profile avatar and select Settings. In the menu that opens, look for the Google Assistant section, and then you go to All Settings or Languages to make sure that the language you want is selected and activation is enabled, and without that step, the system will not be able to recognize your command.

💡

For maximum accuracy of Russian speech recognition in the Assistant settings, select Russian as the main language, and add English as the second if you use both.

And then there's the important step, which is to adjust the voice model, and the system will ask you to say "OK, Google" and "Hey Google" several times, and don't miss this step, because it allows machine learning algorithms to adapt to the timbre of your voice, which is critical for activation without hands.

Also in Popular Settings, make sure that the Google Assistant switch is in the active position. If you plan to use the Assistant on a locked screen, find the appropriate item in the Devices section and allow access. This will allow you to control a smart home or set timers without unlocking your phone.

Replace the Mi Assistant with MIUI system settings

The easiest and most reliable way to replace the built-in assistant is to use the regular capabilities of the MIUI shell or HyperOS. Xiaomi engineers have provided the option to choose the default assistant application, although sometimes this option is hidden quite deep.

Search by settings, type in the word “Assistant” or search for the Additional section (some firmware calls it Advanced Settings). Inside this menu, look for the Select App for the Power button or Press within 0.5 seconds. This is where the switch between Mi Assistant and third-party solutions occurs.

If you find Assistant Choice, click on it. The system will offer a list of available apps. Select Google from the list. After that, any prolonged click on the enable button will call the Google Assistant interface. However, on many global firmware, this item may be missing or blocked.

In this case, it is necessary to check the section of the Annex. → App management. Click on the three dots in the top right corner and select Other Settings or Default Apps. Find the Digital Assistant category and change the value from Mi Assistant to Google.

Using third-party utilities to reassign buttons

In situations where Xiaomi's system settings don't allow you to change the behavior of the power button, specialized utilities come to the rescue. One of the most effective solutions is the Button Mapper app or its counterparts available on Google Play, which intercept button presses and redirect them to start the desired actions.

Once you install the app, you'll need to give it special permissions, and unlike normal programs, Button Mapper requests access to Accessibility, so that the app can "see" which button you press and respond to that event without regard to standard system behavior.

⚠️ Warning: Giving access rights to "Special Features" to third-party apps gives them a high level of control over the device. Use only proven utilities with a good reputation, such as Button Mapper from the company flar2, to avoid data leakage.

In the program interface, find the Buttons section and select Power Button (or Home if you have an old model with a mechanical button). Activate the Customize switch. Now you can assign a Long Press action to start Google Assistant. In the action list, simply select Google Assistant.

Some users are faced with MIUI aggressively killing background processes to save energy. To keep Button Mapper running smoothly, go to Settings → Apps → All applications, find a utility, go to Energy Saving and select No Limits mode. Also pin the application to your recent task list.

Activation of the assistant with voice and from the lock screen

One of the key features of the Google ecosystem is the ability to activate voice without touching the screen. The phrase "OK, Google" works even when the phone is on the table. However, on Xiaomi smartphones, this feature can conflict with the similar feature of Mi Assistant, so it is important to correctly prioritize.

To work voice activation from the screen off, you need the appropriate switchboard in the Google Assistant settings to be turned on. Path to it: Google Settings → Search and Assistant → Google Assistant → Devices → Phone. Make sure that the access point from the lock screen is activated.

And there's also the Quick Phrases feature, which allows you to execute commands like "Reset a call" or "Respond" without saying the word "Google." This is especially useful in situations where your hands are busy. → Quick phrases.

If you want to use swipe activation from the corner of the screen (like on Pixel), on pure Android, this works out of the box, but on MIUI it may require installing a Google Now Launcher launcher or using widgets. However, a standard swipe diagonally from the corner is often reserved for screenshots or other Xiaomi system gestures, so voice control remains the most stable option.

Comparison of Mi Assistant and Google Assistant

Understanding the differences between the two systems will help you make your choice. While both systems are designed to manage your phone, their philosophy and integration with services are radically different. The Mi Assistant is tailored to the Xiaomi ecosystem, while the Google Assistant is tailored to the search engine.

Below is a table showing the key differences in language model capabilities and support:

As the comparison shows, Google Assistant benefits from understanding the context and the naturalness of the dialogue. It is better at handling complex queries such as “find restaurants nearby and show reviews” or “set an alarm for 7 a.m., but only on weekdays.” Mi Assistant is good for managing Xiaomi hardware, but weak in information queries.

Google Assistant also offers Routines, which allows you to run a chain of actions in one sentence, for example, the Good Morning command can turn on music, tell the weather, report traffic jams and start a coffee maker timer. Setting up scripts is available in the assistant profile.

Solving System Problems and Conflicts

During the setup process, users may encounter a situation where, after updating the firmware, the settings are reset and the Mi Assistant is activated again. This is the standard behavior of the MIUI security system, which seeks to return the "native" default settings, in which case the default application selection procedure will have to be repeated.

Another common problem is microphone conflict: If you're trying to activate Google Assistant and it doesn't respond or says "Network is not available," check permissions. Go to Settings → Apps → Google → Permissions. Make sure that Microphone access is allowed at all times, not just when you're using it.

⚠️ Warning: If the short-term Tap to lock stops working after the Button Mapper is installed, this is a known conflict.The solution is in the Button Mapper settings to disable the processing of the short press of the power button, leaving only the long one.

Also worth mentioning is the impact of Do Not Disturb or Sleep mode on the voice assistant. In some scenarios, the system blocks the "OK, Google" activation to keep the user awake. Check the settings in the Digital Well-being section to make sure the assistant is not constrained by the schedule rules.

If nothing works, try clearing the Google cache. Go to Settings → Apps → All apps, find Google, select Memory and click Clear Cache. Don't confuse "Clear All Data" with "Clean All Data" or you'll have to reset your account. After cleaning, reboot your device.
