Many smartphone users notice that after talking about a service or product, relevant offers begin to appear in the advertising feed. This gives rise to the theory that Google is constantly listening to us through the device's microphone. Although the company officially denies using call recordings for advertising targeting, the system does collect a huge amount of data about your interests, location and voice commands.

Completely blocking all information collection channels without turning your smartphone into a “brick” is difficult, since the Android ecosystem is deeply integrated with the corporation’s servers. However, there are a number of effective settings that can significantly reduce the amount of transferred data and disable functions responsible for Continuous listening the environment.

In this instruction we will look at not only disabling the voice assistant, but also clearing the accumulated history, as well as system restrictions on access to the microphone. You will have full control over what data leaves your device.

Disable the voice assistant and the “Ok Google” function

The most obvious source of “wiretapping” is the function of always waiting for a voice command. When this option is active, your smartphone's microphone is in low-power mode, but is technically always active, scanning the airwaves for a trigger phrase. To stop this, you need to change the application settings Google.

Go to the settings of the Google application itself, and not to the general system settings. Find the section responsible for voice control. Here you will see a switch that activates command standby mode. Disabling this option will ensure that the phone stops analyzing audio in the background.

It's also worth deleting your saved voice samples. The system uses them to more accurately recognize your speech, but their presence on servers increases privacy risks. Removing the voice model resets the recognition settings to factory settings.

💡

After disabling the “Ok Google” function, calling the assistant will only be possible by long pressing the Home button or swiping from the corner of the screen, which eliminates accidental activation.

The disabling process is as follows:

  • 📱 Open application Google on your device.
  • 👤 Click on the profile icon in the upper right corner and select Settings.
  • 🎤 Go to the section Google Assistant and select Hey Google and Voice Match.
  • 🚫 Deactivate the switch Hey Google and delete the voice model.

Manage activity and location history

Even if the microphone is turned off, Google continues to build your digital profile based on your search history, places visited, and videos watched. This data is stored in your account and is used to personalize search results and advertising. Without regular cleaning, this information accumulates for years.

The most critical section is the “Application and Web Search History”. This is where everything you typed into the search bar ends up, and often what you dictated by voice. Disabling this feature prevents new entries from being saved, but does not delete old ones.

⚠️ Attention: Completely disabling activity history may impair the performance of some services, for example, smart suggestions in the navigator or personalized news in the Discover feed.

To manage this data, you must go to a special account management center. There you can choose to pause data collection or set up automatic deletion of records older than 3 or 18 months.

System restrictions on access to the microphone

Starting with version Android 12, the system has received improved privacy control tools. A green indicator now appears in the top right corner of the screen whenever an app is using the microphone. This allows you to instantly identify suspicious activity.

You can completely block any application from accessing the microphone through system settings. This is a more reliable method than disabling features within applications, as it works at the operating system level. Even if the app tries to initiate recording, the system will block this request.

It is recommended to audit all installed apps. Social networks, games and flashlights often request access to the microphone for no good reason. Revoking these permissions will not affect the basic functionality of most utilities.

Algorithm for checking permissions:

  • 🛠 Go to Settings smartphone.
  • 🔒 Select section Privacy or Permission Manager.
  • 🎙 Find item Microphone in the list of permissions.
  • 🚫 Disable access for all applications except instant messengers and voice recorder.

☑️ Audit microphone permissions

Done: 0 / 4

Resetting the advertising ID and personalization

Advertising ID is a unique number assigned to your device to track behavior in different applications. Ad networks use it to link your in-game, browser, and app store activity into a single profile.

While it's not strictly wiretapping, resetting this identifier breaks the link between your past and future behavior. The system begins to perceive you as a new user, which confuses the targeting algorithms.

In addition, it is worth disabling ad personalization. This will not remove advertising completely, but it will make it less relevant to your interests, which indirectly reduces the value of the data collected about you for marketers.

What is Advertising ID?

This is similar to cookies in the browser, but for the entire device. It allows advertisers to understand what apps you install and what you buy, even if you are not signed into their accounts.

To perform this operation:

  1. Open Settings and find the section Google.
  2. Go to menu Advertising.
  3. Press the button Reset advertising identifier.
  4. Activate the option Disable ad personalization.

Using advanced developer settings

For advanced users, it is possible to limit the background activity of Google services through the developer menu. This requires caution, as incorrect settings can lead to system instability or battery drain.

One ​​of the useful features is limiting background processes. You can set a limit on the number of processes that can run simultaneously. This indirectly affects the ability of services to collect telemetry in the background.

⚠️ Attention: Do not disable system processes with names containing "System", "Framework" or "Telephony". This may result in loss of connection or inability to load the OS.

To get to this menu, you need to activate developer mode by tapping the build number seven times in the “About phone” section. After this, a new item will appear in the main settings.

Settings → System → For developers → Limit of background processes → No more than 2 processes
💡

Limiting background processes is a radical measure that saves battery and reduces data transfer, but can slow down the receipt of notifications.

Radical measures: Disabling Google services

If your goal is maximum privacy and you are willing to sacrifice convenience, you can completely disable the main Google services. This will turn your smartphone into a device that runs exclusively on AOSP open source code.

Without Google services (GMS), you will not be able to use the official Play Market store, contact synchronization, a map in the navigator, and many popular applications that depend on the Google API. However, the phone will become “invisible” to the corporation’s ecosystem.

This method requires removing system application updates and forcing them to stop. In some cases, it is necessary to obtain root access to completely freeze system packages.

💡

Before disabling Google services, make sure that you have an alternative application store, for example, F-Droid or Aurora Store, to install the necessary software.

Sequence of actions for basic shutdown:

  • 📂 Go to Settings → Applications.
  • 🔍 Find the application Google Services Play.
  • 🗑 Click Uninstall updatesand then Disable.
  • 🔄 Repeat the procedure for the application Google i Google Play Market.
How will this affect the operation of the smartphone?

Most third-party applications will stop working correctly or will not start at all. Notifications from many services will stop coming. Synchronization of photos and contacts will stop. The phone will become safer, but less functional.

Is it possible to enable services back?

Yes, you can always go back to the application settings, select disabled services and click the “Enable” button. The system will offer to update them to the latest version, and functionality will be restored.

Will this help with physical wiretapping?

Disabling services programmatically blocks data transfer. However, if the device is embedded with a hardware bug or malware with root privileges, software settings may be bypassed. For a 100% guarantee, physical modification or the use of specialized firmware is required.

Do you need to delete your Google account?

Deleting the account from the phone settings will break synchronization, but will not delete the account itself. To completely clear your data, you need to go to myaccount.google.com and delete your account permanently, but this will deny you access to mail and other services.

Is it safe to use third-party launchers?

Using launchers that do not depend on Google (for example, Nova Launcher or Niagara) can reduce the amount of telemetry sent about your activities at work desktop, but does not protect against data collection by system services.
