The modern ecosystem of smart devices in Russia is undergoing significant changes, and users are increasingly looking for alternatives to foreign services. One of the most popular requests is the integration of a domestic voice assistant into the everyday use of a smartphone. The question of how to install Marusya by default on Android worries many gadget owners who want to automate calling an assistant by long pressing the power button or home button.
Unfortunately, the architecture of the operating system Android has its own strict limitations. The standard protocol does not allow you to simply replace the system one Google Assistant with a third-party application in one click through the settings. However, there are a number of effective methods to overcome these limitations and achieve the desired result. In this article, we will analyze in detail all the available methods, from standard settings to the use of specialized utilities.
The setup process may vary depending on the version of the operating system and the shell of your smartphone manufacturer. It is important to understand that a complete replacement at the system level is not possible on all devices without obtaining root access. However, for most users, it will be enough to set up call emulation so that Marusya opens instantly at your request.
Features of voice assistants in Android
Before you begin active configuration, you need to understand exactly how the operating system processes voice commands. In the environment Android a system service is responsible for processing a long press of the Home button or power button. By default, this service is strictly tied to applications from Google. This is done to ensure seamless integration of search and other company services.
The application Marusya from VK, despite its functionality, is third-party software. It does not have system privileges to intercept hardware buttons without additional user intervention. That's why simply installing an app from the store doesn't make it your default assistant. You will need to manually reassign actions or use special launchers.
⚠️ Attention: On smartphones with a pure version of Android (Pixel, Motorola) and some Xiaomi or Samsung shells, replacement options may be limited by the manufacturer's security policies. Always check for firmware updates, as they may block previously working button interception methods.
It's also worth noting the difference between voice activation and button activation. The “Hey Google” function works at a deep system level, listening to the microphone even in sleep mode. Marusya also has a voice activation function, but for its stable operation in the background, you need to correctly configure permissions and exceptions from the power saving mode.
Basic installation and initial setup of the application
The first and mandatory step is the correct installation of the application itself. You should not download installation files from third-party resources, as this may lead to data leakage or unstable operation of the service. Use only official sources, such as Google Play Market or RuStore.
After installation, you must complete the initial configuration. Go to the application and log in through your account VK. This is critically important, since it is the account that stores the history of your requests and settings for smart home scenarios. Without authorization, the assistant's functionality will be greatly reduced.
Next, you should grant the application all the necessary permissions. The system may request access to your microphone, contacts, location, and notifications. Denying these rights will make it impossible to carry out many commands, such as “call mom” or “show me how to get home.”
Settings → Applications → Marusya → PermissionsMake sure that microphone access is set to “Always Allowed” or “Allowed During Use,” depending on the Android version. The voice activation function often requires permission to work in the background, which must be confirmed separately in the system pop-up window.
☑️ Initial setup of Marusya
Assigning Marusya as an assistant by default through the settings
On some devices, especially with custom shells from Chinese manufacturers, it is possible to change the assistant directly through the settings menu. This method is the most stable if available on your smartphone. It allows the system to correctly transfer control to the voice assistant during a call.
To check this feature, go to the settings section of your device. The path may vary, but most often it looks like this: Settings → Applications → Default applications. In the list, find “Assistant” or “Voice Assistant”. If the list of available options includes Marusya, just select it.
In other cases, the path may lie through the settings of the Google Assistant itself. Go to the Google app, click on the profile icon and select Settings. Then go to the Google Assistant section and find Assistant Apps. The choice of an alternative service may also be available here.
| Manufacturer | Path to the settings menu | Probability of success |
|---|---|---|
| Xiaomi / Redmi / POCO | Settings → Advanced settings → Buttons | High |
| Samsung | Settings → Display → Home button | Low (requires Bixby) |
| Honor / Huawei | Settings → Accessibility → Virtual navigation | Medium |
| Realme / OPPO | Settings → Convenient tools → Buttons | High |
If, after selecting Marusya as the main assistant, a long press of the button still opens Google, then the manufacturer has blocked this function at the firmware level. In this case, you need to switch to using third-party utilities to reassign buttons.
On Xiaomi smartphones in “Full Screen” mode, the gesture for calling the assistant may conflict with the “Back” gesture. Try switching to classic navigation buttons for more stable operation.
Using third-party applications to reassign buttons
When standard tools do not help, specialized utilities such as Button Mapper or ReMappingcome to the rescue. These applications allow you to intercept hardware button presses and assign them to launch specific apps or actions. This is the most universal way to make Marusya the main one.
After installing such an application, you will need to give it access to special features (Accessibility). The system will warn you that the application will be able to see all your actions on the screen. This is necessary for correct interception of signals from buttons, so confirm the permission.
In the app interface, find the button that you want to reassign. Most often this is the Home button or the power button. Select the “Long Press” action and select “Launch application” as the action. In the list of installed apps, find and select Marusya.
⚠️ Attention: When using applications to reassign power buttons, be careful. An incorrect setting may result in you not being able to turn off the screen or access the shutdown menu in the standard way. Always leave the option to roll back settings.
Some advanced users use scripts in applications like MacroDroid or Tasker. This allows you to create more complex logic: for example, double pressing the volume down button launches Marusya, and a long press turns on the flashlight. Such flexible control opens up wide possibilities for automation.
What to do if the button is not reassigned?
If the Button Mapper application does not see the button press, your firmware may be blocking interception at the system level. Try connecting an external Bluetooth keyboard and assigning an action to its key, or use a widget on the desktop as an alternative.
Voice activation and work in the background
To fully use the voice assistant, it is not enough just to launch it using a button. It is important that it can be activated by voice command even when the screen is off. This requires special power settings, as Android systems tend to kill background processes to save battery.
Go to your smartphone's battery settings. Find the application Marusya in the list and change the operating mode to “No restrictions” or “Do not optimize”. This will prevent the system from terminating the assistant's process, allowing him to constantly listen to the broadcast in search of an activating phrase.
You also need to pin the application in memory. Open the recent applications menu, find the Marusya window and click on the lock icon or select “Pin.” This ensures that when clearing the RAM, the assistant will not be closed.
In the settings of the Marusi application itself, enable the “Voice activation” option. Say a test phrase to check the microphone sensitivity. If the assistant responds with a delay, check whether the “Energy Saving” mode is turned on on the phone, which limits the processor.
Stable operation of voice activation depends 90% on the energy saving settings. Without excluding the application from battery optimization, the “Always Listen” function will not work.
Solving common problems and conflicts with Google Assistant
Even after careful configuration, users may encounter a situation where, when calling the assistant, it is not Marusya that opens, but Google. This occurs due to conflicting priorities. The system may automatically reset to default settings after updating Google Play Services components.
To resolve this issue, try clearing Google app data. Go to Settings → Applications → Google → Storage → Clear data. Don't worry, this won't delete your account, but it will reset some assistant settings, after which the system will ask you again to choose an assistant the next time you press the button.
Another common problem is response delay. If Marusya opens up, but “thinks” for a long time before answering, check the speed of your Internet connection. Voice requests are processed on servers, so a stable Wi-Fi or 4G/LTE is critical for performance.
In some cases, reinstalling the application and completely clearing the cache helps. Uninstall Marusya, restart your smartphone and install it again. This often solves errors associated with incorrect registration of services in the system upon first launch.
Is it possible to completely remove Google Assistant after installing Marusya?
Complete removal of Google Assistant without root access is impossible, since it is a system application. However, you can disable it in application settings to prevent it from consuming resources and hijacking control. Marusya will work independently.
Why doesn’t Marusya hear the command when the screen is off?
Most likely, the application was closed by the system to save energy. Check your battery settings and make sure Marusya's permission is set to run in the background without restrictions. Also check the microphone settings in the system.
Does reassigning buttons work on Android 13 and 14?
Yes, it works, but Google has tightened its security policies. Standard apps like Button Mapper may require additional permissions via ADB or running in accessibility mode. On some new smartphones, reassignment of the power button is blocked by software.
How to change Marusya's voice or her name?
In the settings of the Marusya application, you can select different voices for voicing answers. However, changing the activation name (the phrase to which it responds) is usually not possible, since this is hard-coded into the speech recognition algorithms on the server.
Is it safe to give the Button Mapper application access to accessibility features?
The Button Mapper application has a good reputation and is open source in some versions. Accessibility access is technically required to intercept clicks. However, download such utilities only from trusted stores to avoid malware.
