How to permanently turn off the volume keys on Xiaomi: official and hidden methods

The physical volume buttons on Xiaomi smartphones are often a source of irritation: random taps in your pocket, children playing with your phone, or simply a desire to protect the device from unauthorized sound changes. Unlike software-based screen locking, disabling hardware keys requires deeper settings — from standard features. MIUI beforehand ADB-commands or specialized utilities.

In this article, we will discuss all the current ways to deactivate the volume buttons on Redmi, POCO and Mi models (including Xiaomi 12/13/14, Redmi Note 10/11/12 and others). Importantly, some methods require unlocking the bootloader or root rights - we will specify where this is necessary and warn about the risks. If you need to temporarily block the buttons (for example, during the game), pay attention to the section on the "Do not disturb" mode.

Warn in advance: Disabling the hardware keys can make it difficult to control the phone in emergency situations (for example, when the system freezes or the need to quickly turn off the alarm clock).

1. Method: Do not disturb mode (temporary lock)

The easiest and safest method is to use the built-in Do Not Disturb (DND) mode, which does not physically turn off buttons, but ignores their pressing in the background, and is suitable for situations where you need to prevent accidental changes in volume (for example, while sleeping or shooting a video).

How to turn on:

• 📱 Open the Settings. → Sound and vibration → Don't disturb.
• 🔄 Select Schedule or Manually Activate.
• 🔕 In the Rules section, make sure to turn on the Disable Volume buttons (not available on all firmware).
• ⚙️ For MIUI 14: Go to Additional → Control buttons and mark Block Volume Change.

Limitations of the method:

• ❌ Does not work in active applications (for example, in a player or game).
• ❌ Does not block buttons when the screen is unlocked.
• ❌ In some models (POCO F4, Redmi K50) The option is hidden in the Settings for developers.

Method: Settings for developers (without root)

MIUI has a hidden option to disable the system's response to hardware keystrokes, and you need to activate Developer Mode and make configuration changes.

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find the item "Disable volume key" (in English firmware - Disable volume key). If it is not, use the search by settings.
4. Turn on the option and restart the device.

Important: MIUI 13+ firmware may not have this item, so try an alternative route:

Settings → Special features → Managing physical buttons → Turn off volume buttons

⚠️ Note: On some models (Xiaomi) 11T, Redmi Note 10 Pro) after the buttons are turned off through developer mode, they stop working even in safe mode.

3. Method: ADB-Teams (for experienced users)

If the standard methods don’t work, you can use Android Debug Bridge (ADB) — It's a low-level system management tool, and it doesn't require root, but it does require a computer and a computer. USB-cable.

Instructions:

1. Install. ADB-PC drivers.
2. Enable USB debugging in the developer settings on your phone.
3. Connect the phone to your computer and type in the command line:

adb shell settings put global volume_key_disabled 1

To return the buttons, use:

adb shell settings put global volume_key_disabled 0

Advantages of the method:

• ✅ It works on all versions. MIUI (including MIUI 14).
• ✅ Does not require superuser rights.
• ✅ Reversible process.

⚠️ Attention: After updating the firmware settings ADB Some banking applications (e.g. SberBank Online) also block the work on devices with debugging enabled. USB.

4. Method: Applications for button blocking

If you don't want to dig into the settings, you can use third-party utilities.

Selection recommendations:

• 🎯 For temporary locking suitable Volume Button Controller – it is simple and does not require rights.
• 🔧 For flexible settings (for example, turn off buttons only in certain applications), use Tasker.
• ⚙️ If you have root, GravityBox will give you maximum control.

Example of settings in Button Mapper:

1. Install the app from Google Play.
2. Grant permission for Special Features (in your phone settings).
3. Select Volume buttons → Shut down.
4. Save the profile and restart the device.

💡

If the buttons are not locked stable after installing the application, add it to the exception list in the battery settings (Settings → Battery → Battery Optimization → All applications → Button Mapper → No restrictions).

5. Method: Editing system files (root only)

The most radical method is to manually change Android configuration files, which is only suitable for users with unlocked bootloader and root rights. Wrong actions can lead to a device blink!

Instructions:

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Go to /system/usr/keylayout/.
3. Find the files: Generic.kl qwerty.kl (or another, depending on the model)

key 24   VOLUME_UP


key 25   VOLUME_DOWN

#

#key 24   VOLUME_UP


#key 25   VOLUME_DOWN

644

⚠️ Warning: After the firmware update, the changes will reset! also some models (Xiaomi) 12S Ultra, POCO F5) have protection against editing system files - in this case, you will need to disable dm-verity via Magisk.

💡

System file editing is the only way to completely disable the kernel volume buttons. All other methods work at the OS level and can be bypassed in Safe Mode or when settings are reset.

6. Method: Hardware lock (extreme case)

If software methods don’t help or you want to physically lock buttons (for example, on a child’s phone), you can resort to mechanical solutions:

• 🛡️ Button lock case – special cases (such as Spigen Tough Armor) have thickened edges that block access to the keys.
• 🔧 Film or Scotch – temporary solution: stick a thin film over the buttons (does not interfere with charging, but blocks pressings).
• 🔨 Disassembly of the phone is an extreme option: undo the buttons from the board (requires soldering skills and risks canceling the warranty).

Warning: Hardware locking can complicate maintenance, such as Xiaomi service centers that may refuse warranty repairs if they find traces of a body opening.

Frequent problems and solutions

Even after successful button disabling, users face unexpected challenges, and consider typical scenarios:

• 🔊 The buttons are back on after the update. → Repeat the procedure (especially relevant to the ADB and editing system files).
• 🔋 The phone does not respond to other buttons. → Reset settings through Settings → System system → Resetting settings.
• 🛑 Hanging when pressing buttons → Remove conflicting applications (such as MacroDroid or Automate).
• 🔒 The lock is not working in safe mode → This is normal: Safe mode disables all third-party settings.

If none of the methods worked, check:

• 📱 Compatibility of your model with the chosen method (for example, Xiaomi Civi 3 may have a unique firmware).
• 🔄 Version MIUI — Some features are only available in global or Chinese builds.
• 🛠️ Custom firmware (e.g. Pixel Experience or LineageOS) – they can ignore settings MIUI.
