How to disable eavesdropping in Xiaomi phone: all ways to protect privacy

Xiaomi smartphone owners often wonder if their device can eavesdrop on conversations, a topic that has become especially relevant after scandals with data leaks and accusations against Chinese manufacturers of collecting information without user consent. It is important to understand that modern smartphones do have many sensors, including microphones, which can theoretically be used to collect unauthorized audio data.

In this article, we’ll look at all the ways you can disable eavesdropping on Xiaomi devices, including Redmi models, POCO You'll learn how to block microphone access for applications, disable voice assistants, check background activity, and even physically turn off the microphone if necessary. MIUI 14/15 hyperos.

It is worth noting that a complete shutdown of the microphone at the software level is impossible without root rights, since the Android operating system always leaves minimal rights for system processes. However, the combination of these methods will minimize the risks. If you use the device to work with confidential information, we recommend you to additionally study the section on physical locking of the microphone.

1. Verification of application permissions to access the microphone

The first step to protecting your device is to audit all the applications that have access to your microphone, and many programs (social networks, instant messengers, games) request this permission "just in case," but don't actually need it for basic functionality.

To check and disable unnecessary permissions:

• 📱 Open the Settings. → Annexes → Application management
• 🔍 In the search bar, type in “microphone” or scroll to the Application Resolution section. → Microphone
• 🚫 Disable access to all suspicious apps (especially those you don’t use for voice calls)
• 🔄 Restart the device to make the changes effective

Note system applications like com.miui.voiceassist (Xiaomi voice assistant) and com.google.android.googlequicksearchbox (Google Assistant), which can affect the functionality of the device, but significantly reduce the risk of unauthorized recording.

⚠️ Note: Some apps (such as TikTok or Facebook) may request access to the microphone to “improve targeted advertising.

2. Disabling voice assistants and voice control functions

Voice assistants are the main potential source of audio leakage, and Xiaomi smartphones have several of them:

• 🤖 Xiao AI (Xiaomi's built-in assistant)
• 🎤 Google Assistant (if Google services are installed)
• 📱 Voice dialing and gesture control functions

To completely deactivate them:

1. Xiao shutdown AI: Go to Settings. → Additionally. → Xiao AI Turn off the "Voice Assistant" and "Voice Awakening" sliders in the "Permissions" section, disable access to the microphone

Deactivation of Google Assistant:

• Open the Google app → tap on the avatar → Settings → Google Assistant
• Select the device and turn off the option "Google Assistant"
• In Android settings (Settings) → Annexes → Google to ban access to microphone

For models with HyperOS, the path may be slightly different. If you do not find these points, use a search by settings (the magnifying glass icon in the upper right corner).

3. Blocking background microphone activity

Even after the permissions are turned off, some system processes can activate the microphone in the background to prevent this from happening:

1. Limit background activity:

• 🔄 Go to Settings. → Annexes → Application management
• 📊 Select the application → Battery → Background activity → Limit
• 🚫 For critical applications (messengers, social networks) set the restriction "Strictly"

2. Turn off optimization MIUI:

• 🔧 Enter the Settings → About the phone several times in a row to activate the developer mode
• 🛠 Back to Settings → Additionally. → For developers
• 🔘 Turn off options: Optimization MIUI Auto-Run Applications (for Unnecessary Programs)

These measures will not only reduce the risk of eavesdropping, but also extend battery life, but note that some features (such as real-time notifications) may not work properly.

💡

To check which apps have recently used a microphone, go to Settings → Confidentiality → Permits journal → Microphone. This is a history of access over the last 24 hours.

Physical shutdown of the microphone (for emergency cases)

If you want a 100% guarantee that the microphone is not working, you can use physical locking methods, which is true for journalists, business people or those who work with sensitive information.

Methods of physical disconnection:

• 🔌 Earphone plug retrieval: With headphones connected with a microphone, the device's built-in microphone automatically shuts down. You can use faulty headphones without speakers, leaving only the microphone plug in the socket.
• 🛠 Disassembly of the device: On most Xiaomi models, the microphone is located next to the bottom speaker. It can be soldered off or snacked on the track on the board (requires soldering skills).
• 📦 Use of lock cases: There are special covers with metallized mesh that shield electromagnetic signals (for example, Faraday covers).

For models with a non-removable battery (for example, Xiaomi 13 Pro or Redmi Note 12), disassembly requires special care, after physical disconnection of the microphone will lose the ability to voice calls, record video with sound and use voice notes.

⚠️ Attention: Physical interference with the device design voids the warranty and can cause permanent damage. If you are unsure of your skills, contact the service center to request that the microphone be turned off "for medical reasons" (some workshops take this step).

5. Checking the device for spyware

Even after all the settings, there is a risk that the device has specialized spyware that can bypass standard restrictions, such programs may masquerade as system processes or legitimate applications.

Signs of infection:

• 🔋 Unexplained increase in battery consumption
• 📶 Increased mobile data traffic in the background
• 🔊 Extraneous noises or echoes during calls
• 📱 Spontaneous microphone switching on (can be checked through the indicator in the status bar)

How to check and remove spyware:

1. Install a deep scanned antivirus (such as Kaspersky or Bitdefender).
2. Check the list of running processes through Settings → Applications → Launched.
3. Use special utilities like Malwarebytes or 360 Security.
4. If suspected, reset to factory settings (Settings) → The phone. → Resetting settings).

If suspicious activity persists after reset, this may indicate:

• 🛠 Built-in spyware at the firmware level (relevant for "gray" devices)
• 🔄 Vulnerability in the modem module (requires flashing through Fastboot)

💡

On devices with root rights, you can use the NetGuard or AFWall application+ Completely block network access for suspicious processes.

6. Alternative methods of protection against wiretapping

In addition to turning off the microphone, there are additional measures to protect privacy:

1. Use of secure messengers:

• 🔒 Go to messengers with end-to-end encryption: Signal, Session, Telegram (secret chats).
• 🚫 Avoid sending sensitive information via WhatsApp or Viber – they have vulnerabilities in encryption protocols.

2.Tune in. VPN firewall:

• 🌍 Use it. VPN with a tracking lock function (e.g., ProtonVPN or IVPN).
• 🛡 Install NetGuard Firewall (requires root rights) to block suspicious connections.

Regular inspections:

• 🔄 Monthly review the list of apps with microphone access.
• 📋 Keep a log of installed programs – delete unused ones.

Hardware solutions:

• 🎧 Use an external microphone with a physical switch (such as a Plantronics headset with a mute button).
• 📡 For critical conversations, use a separate “clean” device (e.g., GrapheneOS on Google Pixel).

The combination of these techniques creates layered protection that makes it much harder for potential listeners to do so, but remember that 100% anonymity doesn’t exist in the digital world — always assess risks and make informed decisions.

7. Frequent bugs and myths about eavesdropping on Xiaomi

There are many myths surrounding the topic of smartphone wiretapping, and we'll look at some of the most common ones.

❌ Myth 1: “Xiaomi always sends data to China"

✅ Xiaomi does collect telemetry (like other manufacturers), but:

• The microphone data is not transmitted by default.
• In Europe and Russia, there are local servers for data processing (due to the fact that the data is not processed by the Internet). GDPR).
• You can turn off telemetry collection in Settings → Memory. → Send an error report.

❌ Myth 2: If the microphone indicator is not on, the recording is not going"

✅ Reality: Status bar indicator only appears when legitimate applications use the microphone actively.

❌ Myth 3: “It is enough to disable access to the microphone in the settings"

✅ Reality: Some system processes (e.g., mediaserver) can activate the microphone at a low level.

❌ Myth 4: “The wiretapping only goes through the microphone"

✅ Reality: Current surveillance techniques include:

• 📍 Analysis of accelerometer data (vibrational speech can be restored).
• 🔊 Using a speaker as a microphone (via echo location).
• 📡 Traffic interception through vulnerabilities in the module Wi-Fi/Bluetooth.

To truly protect yourself, you need a comprehensive solution: a combination of software constraints, hardware measures and conscious behavior when using the device.
