How to completely disable wiretapping on the Xiaomi Redmi Note phone: 7 working methods

Owners of Xiaomi Redmi Note smartphones often wonder whether it is possible to disable potential wiretapping through a microphone or data leak through applications? Despite the fact that the manufacturer claims to protect privacy, MIUI (the branded shell of Xiaomi) has settings that can transmit audio data invisibly. In this article, we will discuss all possible ways to block wiretapping, from turning off the microphone at the system level to checking the access rights of applications and using specialized tools.

It’s important to understand that Xiaomi Redmi Notes (including Note 10/11/12/13 Pro models) run on Android with a MIUI shell that has its own data collection mechanisms. Even if you haven’t installed suspicious programs, some system services (such as miui.analytics or com.xiaomi.midrop) may request access to the microphone. We’ll show you how to completely block access to audio recordings without root rights, and we’ll also look at radical methods for users with an unlocked bootloader.

We warn you that some actions (such as disabling system applications) can disrupt the stability of the phone, all manipulations you perform at your own risk.

1. Verification of application permissions to access the microphone

The first step is to audit all the programs that have access to the microphone. In MIUI, this is done through the Settings menu → Apps → Permissions → Microphone. Here you will see a complete list of active-access applications.

• 🔍 Social media (Facebook, VK, TikTok – They often request a microphone for voice messages, but can use it in the background.
• 📱 System Services (com.miui.voiceassist, com.xiaomi.aiasst) – Xiaomi voice assistants can record audio to improve recognition.
• 🎮 Voice chat games (PUBG Mobile, Free Fire – Even after leaving the game, some customers continue to listen to the microphone.
• 🛡️ Antiviruses and “optimizers” – programs like Clean Master or 360 Security sometimes gain access to the microphone under the pretext of “protection".

Turn off permission for all suspicious applications, and if the program then stops working, it actually used the microphone for basic functions (like WhatsApp for voice calls), otherwise it is too risky.

⚠️ Note: Some applications (e.g. Google Assistant or Mi) AI) They can automatically enable access to the microphone after the update. 1-2 month.

For convenience, use the checklist:

2. disable Xiaomi system services related to audio recording

MIUI has a few built-in services that can use the microphone without you knowing:

To disable these services:

1. Go to Settings → Applications → Application Management.
2. In the search, type the name of the package (for example, com.miui.voiceassist).
3. Click Disable (if the button is inactive – first click Stop).
4. Confirm the action in the window that appears.

If the Disable button is missing, the service is protected by the system, in which case only deletion through ADB will help (see section 5).

⚠️ Note: Disabling com.miui.analytics may cause Mi Account and Xiaomi cloud services to crash. If you use contact or note synchronization, it’s best to keep the service active but limit it to the microphone in the resolutions.

3.Use of Do Not Disturb mode to lock microphone

Little-known fact: MIUI has a hidden feature that can completely block microphone access for all applications except system calls, activated via Do Not Disturb mode with additional settings.

Instructions:

1. Open Settings → Sound and vibration → Do not disturb.
2. Select Rules → Add Rules → Events.
3. Set the trigger manually and name a rule (e.g., "Mic Lock").
4. In the Exclusions section, disable all items except Calls and Alarms.
5. Activate the rule and check: the microphone should stop working in third-party applications (for example, in a voice recorder or WhatsApp).

This method doesn't shut down the microphone completely (system calls will work), but it blocks it for all other programs, minus you having to manually turn on/off the rule if necessary.

Physically shutting down the microphone (for advanced users)

If you need to securely turn off the microphone at the hardware level, there are two radical ways:

• 🔧 Flashing with microphone drivers removal – requires unlocked bootloader and firmware modification knowledge. Suitable for Redmi Note 10 Pro and newer models.
• 🛠️ Physical disconnection of microphone contacts – you need to disassemble the phone and cut the paths on the motherboard (irreversibly!).

For the first method, you will need:

1. Unlock the bootloader via fastboot oem unlock (instructions on the official Xiaomi website).
2. Install custom recovery (TWRP or OrangeFox)
3. Find and edit the file vendor/etc/mixer_paths.xml, Delete the lines associated with the microphone (mic).
4. Reflash the phone with modified firmware.

This method is only suitable for power users! firmware errors can lead to a "brick" (complete inoperability) of the phone.

5. Disconnecting the microphone via ADB (no root rights)

If you don’t have root access, but you have a computer, you can turn off the microphone for all apps via Android Debug Bridge (ADB), a method that is temporary (resets after the reboot), but effective.

Instructions:

1. Enable USB Debugging in Settings → About Phone → MIUI version (click 7 times on the point to activate Developer Mode).
2. Connect your phone to your PC and confirm your trust in your computer.
3. Open the command line (Windows) or the terminal (Mac/Linux) and type:

adb shell pm revoke com.android.microphone android.permission.RECORD_AUDIO


adb shell pm revoke com.miui.voiceassist android.permission.RECORD_AUDIO




adb shell pm revoke com.xiaomi.aiasst android.permission.RECORD_AUDIO

These commands are revoking audio recording permissions from key system applications, and to get access back, replace revoke with grant.

⚠️ Note: After completing these commands, some features (e.g., voice search in Google or Mi) are performed. AI) It may also cause a camera malfunction (some modes use a microphone to record video).

6. Check for spyware and viruses

Even if you've disabled all permissions, you can have spyware installed on your phone that bypasses the system's limitations.

• 🔋 Unexplained battery consumption (e.g., the phone runs out overnight without active use).
• 📶 Active traffic in the background (check in Settings) → SIM-maps and mobile networks → Traffic).
• 🎤 The microphone is turned on by itself (the indicator of the record in the status bar).
• 📱 Unknown applications in the list of installed programs.

To verify:

1. Install an antivirus with a good reputation (Malwarebytes, Bitdefender, Kaspersky).
2. Scan your phone in Safe Mode (click the shutdown button → Safe Mode).
3. Check the list of running processes through Settings → Applications → Launched.
4. Use specialized tools like NetGuard (network traffic blocker) or AppOps (hidden permissions viewer).

If you find suspicious software, delete it and reset settings (Settings → Additional → Resetting).

💡

Before resetting, back up your important data via Settings → About Phone → Backup. After reset, restore only contacts and photos – it’s best to install the apps again to prevent re-infection.

7.Alternative methods: disconnection of the network and use of containers

If you need to guarantee that you will not have data leakage, consider the following options:

• 🌐 Disconnecting mobile data and Wi-Fi — without a network, your phone can't transmit audio anywhere.
• 📦 Using Shelter or Island – these apps create an isolated user profile where you can run suspicious programs without accessing the microphone of the main system.

The most reliable option is Shelter, which is an open source application that creates a sandbox for unnecessary programs, and install it from F-Droid, and move all the applications you don't trust there.

💡

Even if you have disabled all permissions, some apps can exploit Android vulnerabilities to covertly record audio.Regularly update your firmware and keep an eye out for news about MIUI security.
