How to completely disable wiretapping on a Xiaomi phone: 7 working methods

Smartphone owners Xiaomi often face suspicions that their device can listen to conversations or transfer personal data to third parties. These fears are not always unfounded: the manufacturer actually integrates analytics collection functions into the firmware, and some applications request access to the microphone without explicit need. But are there real ways to disable wiretapping on MIUI analytics collection functions, and some applications request access to the microphone without explicit need. But are there real ways to disable wiretapping on Androiddevices Xiaomi without compromising functionality?

In this article we will examine 7 proven methodswhich will help minimize the risks of unauthorized access to the microphone and other sensors. It is important to understand: complete isolation from wiretapping is only possible if the microphone is physically disconnected (which is not possible on most models), but proper system settings and application control will reduce the likelihood of data leakage to a minimum. We will not consider extreme measures like flashing to LineageOS —we will focus on solutions available to the average user.

1. Checking microphone permissions: which applications are listening to you

The first step is to audit the applications that have access to the microphone. Even legitimate apps (for example, Google Assistant or Mi Voice) can activate wiretapping in the background. To check and disable unnecessary permissions:

1. Open Settings → Applications → Permissions → Application Permissions.
2. Select Microphone.
3. View the list of applications with access. Disable permission for suspicious or unnecessary apps (for example, games, browsers, social networks).

Pay special attention to system services:

• 🔍 Mi Voice — voice assistant Xiaomi, which can be activated by voice even on a locked screen.
• 🔍 Google — services Google Play and Assistant often request the microphone to recognize commands.
• 🔍 Mi Browser is a browser from Xiaomithat sometimes accesses the microphone to "improve the user experience."

Some applications (for example, WhatsApp or Viber) really need access to the microphone for voice calls. In this case, it is better to limit background activity:

4. In the settings of a specific application, select Permissions → Advanced → Background activity.
5. Disable the option Allow work in the background mode.

2. Disabling system data collection services in MIUI

The firmware MIUI is known for integrated analytics tools that send data to servers Xiaomi. Some of them may use the microphone to “improve the quality of services.” To disable these functions:

1. Go to Settings → About phone and tap 7 times on the item MIUI versionto activate Developer mode.
2. Go back to the main settings and open Advanced → For developers.
3. Find the option Sending reports on errors and disable it.
4. In the same menu, deactivate Automatic sending of usage data.

Next go to Settings → Privacy → Special permissions → Sending diagnostic data and disable all switches. This will stop the transfer of:

• 📊 Application usage logs.
• 📊 Location data.
• 📊 Information about connected devices (for example, Mi Band).

What happens if you turn off diagnostics?

The smartphone will continue to work normally, but Xiaomi will stop receiving data about your activity. However, some functions (for example, automatic security updates) may work less stable.

On models Xiaomi s Android 12+ an option has appeared Approximate locationthat limits application access to exact coordinates. Activate it in Settings → Privacy → Permissions → Location for additional protection.

3. Removing pre-installed spy applications

Xiaomi preinstalls a number of services on your devices that can collect data without the user’s knowledge. Some of them cannot be removed using standard means, but they can be deactivate or freeze.

Application	Purpose	Risks	How disable
Mi Analytics	Collection of usage statistics	Transfer activity data to Xiaomi	Disable in Settings → Applications → Manage applications → Mi Analytics → Disable
Mi Browser	Browser with integrated analytics	Collection of browsing history and microphone data	Uninstall updates and disable them in the application settings
Clean Master (on older models)	System optimizer	Access to files and processes	Deactivate in Settings → Applications
Mi Credit	Financial services	Collection of personal data for credit scoring	Delete via Settings → Applications → Delete

To completely remove system applications you will need root access, but this is risky: you can disrupt the stability of operation MIUI. use ADB (Android Debug Bridge) to deactivate:

adb shell pm uninstall -k --user 0 com.miui.analytics
adb shell pm uninstall -k --user 0 com.android.browser

These commands will delete Mi Analytics and Mi Browser for the current user without root. ADB see the official documentation Android.

4. Setting up a firewall to block suspicious connections

Many applications transfer data to external servers. including audio recordings. To block these connections, you can use a firewall. Without root access, the application Xiaomi The app will work without root access NetGuard (free, without unnecessary water): data-i="147">Activate it in

1. Install NetGuard from Google Play.
2. Activate it in Settings → VPN (the application creates a local VPN to filter traffic).
3. In the main window NetGuard disable Internet access for suspicious applications (for example Mi Analytics or Mi Browser).
4. Enable the option Block when roamingto avoid data transfer in the background.

Available for advanced users AFWall+ (requires root). It allows you to create rules for system processes, for example, block network access for mediaserver, which is responsible for processing audio.

Disable Internet for Mi Analytics|Block background data transfer|Activate traffic log|Check for suspicious IP addresses-->

Pay attention to the domains to which applications connect. For example, addresses like .miui.com or .xiaomi.com are often used to transmit analytics. In NetGuard you can create rules for blocking specific domains:

5. Open the application settings in NetGuard.
6. Select Domains and add to the black list:

   data.mistat.xiaomi.com
   sdkconfig.ad.xiaomi.com
   api.brs.intl.miui.com

5. Physically blocking the microphone: hardware solutions

If software methods seem insufficient, consider muting the microphone. They are guaranteed to interrupt any access to the audio recording, but have limitations: hardware methods mute the microphone. They are guaranteed to interrupt any access to the audio recording, but have limitations:

• 🔇 Mechanical plug: sticker on the microphone (sold in accessory stores). Minus - blocks all microphones, including the one used for calls.
• 🔇 Case with a metallized mesh: shields electromagnetic signals, but can worsen network reception.
• 🔇 Disconnecting the microphone through disassembly: physical soldering of contacts (requires repair skills and voids the warranty).

On some models Xiaomi (for example, Redmi Note 10 Pro or POCO F3) the microphones are duplicated: one is used for calls, the other for noise reduction. In this case, the plug of the main microphone (usually located next to the connector USB-C) can leave the backup one working.

To temporarily mute the microphone during important conversations, you can use the "Airplane" mode on with Wi-Fi:

• Activate Airplane mode in the notification shade.
• Turn on Wi-Fi manually (this will unlock access to the Internet, but will disable cellular communications and the microphone for calls).

6. Alternative firmware: when to switch to AOSP

If you are not satisfied with the data collection tools built into MIUI the radical solution is to flash it to Android without modifications from Xiaomi. Popular options:

• 📱 LineageOS: "clean" Android without unnecessary services. Supports most models. flashing includes: Xiaomi (For example, Redmi Note 9 Pro, POCO X3).
• 📱 Pixel Experience: firmware with functionality Google Pixel, but without integrated analytics Xiaomi.
• 📱 Havoc-OS: Customizable open source firmware.

The flashing process includes:

1. Unlocking the bootloader via fastboot oem unlock (voids the warranty!).
2. Installing custom recovery (TWRP).
3. Flash firmware and GApps (if needed services Google).

Risks of flashing

Loss of warranty|Possible "brick" (inoperability) of the device|Lack of security updates from Xiaomi|Unstable operation of the camera or sensors

Before flashing, check the compatibility of your model on the forum XDA Developers. For example, for Xiaomi Mi 11 suitable LineageOS 20, and for Redmi 9A only unofficial assemblies.

Important: after flashing to custom firmware without Google Services Some applications (for example, banking) may stop working due to lack of certification Google Play Protect.

7. Regular check for spyware

Even after all the settings, there is a risk of infection with spyware (for example, through phishing links or vulnerabilities in MIUI). Software:

1. Install an antivirus with a permission scanning function, for example, Malwarebytes or Bitdefender.
2. Check the list of running processes through Developer Options (Settings → Advanced → For developers → Running processes).
3. Use ADB to search for suspicious packages:

   adb shell dumpsys package | grep "unknown"

   This command will display a list of applications with unknown sources.

Signs of spyware on Xiaomi:

• ⚠️ Unexplained increase in traffic (check in Settings → SIM cards and mobile networks → Traffic).
• ⚠️ Rapid battery drain in standby mode.
• ⚠️ The appearance of unfamiliar files in the folder /sdcard/ (for example, audio_records).
• ⚠️ The microphone turns on spontaneously (the indicator blinks in the status bar).

If you find a suspicious application, uninstall it and reset the network settings (Settings → SIM cards and mobile networks → Reset network settings) to interrupt possible remote connections.

FAQ: Frequently asked questions about wiretapping on Xiaomi

Can Xiaomi listen to my conversations through built-in services?

Xiaomi officially states that it does not conduct targeted wiretapping, but collects data to improve services (for example, voice assistant Mi AIThis data may include). short audio snippets if you have given permission to access the microphone. To completely eliminate audio transmission, disable Mi Voice and Google Assistantas described in section 1.

How to check if the microphone is working in the background?

On Android 12+ an indicator (green dot) appears in the status bar when the application uses a microphone or camera. You can also use the application Access Dots (for older versions Android), which shows the activity of the sensors. Another way is to start recording sound through another device and check whether it detects noise (if the microphone is turned on, an echo will be heard).

Will the banking application work after disabling all permissions?

Most banking applications (for example, SberBank Online or Tinkoff) require access to the microphone for voice authorization or video identification. If you disable this permission, some functions (for example, confirming transactions by voice) will become unavailable. (transfers, payments) will work. We recommend leaving access to the microphone only for banking applications and disabling it for others.

Is it possible to disable wiretapping without root access?

Yes, most of the methods in this article (setting permissions, firewall, deleting pre-installed applications via ADB) do not require root. However, some system services (for example, mediaserver) cannot be completely blocked without superuser rights. In this case, only flashing to a custom version will help. data-i="267">How to protect yourself from wiretapping via Bluetooth devices? Android.

How to protect yourself from wiretapping via Bluetooth devices?

Intruders can connect to your smartphone via Bluetooth and activate the microphone if the device was previously paired (for example, through headphones or a car system). To prevent this:

• Disable Bluetoothwhen not in use.
• Remove unknown devices from the list of paired devices (Settings → Bluetooth).
• Activate the option Hidden mode (if available on your model).
• Use applications like Bluetoth Auto Connect to control connections.
