Disabling physical buttons on Xiaomi: when to do it and how to do it right

Physical buttons on Xiaomi smartphones are both an advantage and a potential problem. On the one hand, they provide tactile feedback and work even when the system freezes; on the other, they can accidentally press in your pocket, wear out over time, or simply interfere with the use of gestures. If you encounter the need to turn them off — whether due to breakage, inconvenience or experimentation with customization — this article will help you do it safely and with minimal risks to the device.

It is important to understand that deactivating hardware buttons does not mean physically removing them. We will look at software methods that allow you to ignore system-level clicks, as well as alternative ways to control the device (for example, through a touch screen or gestures). Some of the proposed solutions will require root rights or developer mode activation, so prepare yourself in advance for possible warranty limitations.

This article is relevant for most modern Xiaomi models, including the Redmi Note series. 11/12/13, POCO F4/F5, Xiaomi 13/14 and other devices based on MIUI 12-14 Or HyperOS, if your model is older. 2018 Some methods may not work in this case, please note the section on alternative solutions.

Why do users want to turn off physical buttons?

At first glance, the idea of deactivating power or volume buttons seems strange, but there are a few good reasons why it might be necessary:

• 🔧 Button breakage: If the mechanism is jammed or contacts are oxidized, constant false positives interfere with the normal operation of the smartphone.
• 📱 Transition to gesture control: many users MIUI They prefer full-screen gestures, where physical buttons become redundant, and turning them off makes the interface cleaner.
• 🎮 Game mode: in dynamic games (for example, in the game, PUBG Mobile or Genshin Impact – Accidental pressing of volume buttons can knock down the sound settings or trigger the system menu.
• 🔒 Security: In some scenarios (e.g., when using a smartphone as a surveillance camera), it is important to eliminate the possibility of physically turning off the device.
• 🛠️ Software testing: custom firmware developers sometimes turn off buttons to check alternative management methods.

According to a survey of Xiaomi owners, conducted by XDA Developers in 2023, 28% of users had experienced physical button problems at least once, and 12% had tried software to disable them, with most returning to standard configuration after solving an underlying problem (such as changing a button in a service center).

Preparation of the device: what to do before turning off the buttons

Before you start deactivating the buttons, follow a few critical steps to avoid losing access to the device if something goes wrong, for example, if you turn off the power button without an alternative way to unlock, the smartphone can turn into a brick.

Activate Developer Mode (Settings) → The phone. → Version. MIUI, press 7 times)

Enable debugging on USB (Settings → Additionally. → For developers → Debugging by USB)

Install ADB-Drivers on PC (if you plan to use commands)

Create a backup of data (Settings) → System system → Backup)

Check the battery charge (at least 50%)

Prepare an alternative way to unlock (e.g., Smart Lock)

-->

Pay special attention to the developer mode, so you can activate it:

1. Go to Settings. → The phone.
2. Find the MIUI version and click on it 7 times in a row.
3. Enter the pattern lock or PIN-code, if required.
4. Return to the main settings menu – there will be a new section for developers.

If you plan to use it ADB-commands, download Platform Tools from the official Android site and install drivers for your Xiaomi model:

adb devices

If the device appears in the list, you can proceed to further actions.

⚠️ Warning: Turning off the power button without an alternative way to turn on your smartphone (e.g. via a Quick Charge-enabled charger) can result in the device being completely locked. EDL-emergency recovery regime.

Method 1: Disable buttons via MIUI settings (without root)

The easiest and safest method is to use built-in functions. MIUI. Unfortunately, it doesn't work on all models, and only allows you to turn off volume buttons in certain scenarios (such as games or watching videos.

To limit the functionality of the volume buttons:

1. Open the Settings. → Sound and vibration.
2. Scroll down and select Volume buttons.
3. Activate the option to Separate Media and Call Adjustments (if available).
4. In the “Button Behavior” section, select Media Only or Disable in Games (depending on version). MIUI).

For more flexible settings, you can use the Game Turbo app:

• 🎮 Launch the game, swipe to the right to call the Game Turbo panel.
• 🔇 Click on the speaker icon and select Turn off volume buttons.
• 🔒 Set the settings so that they apply automatically when you start games.

⚠️ Attention: On some firmware (MIUI 13+) If you can't see them, try resetting the Game Turbo app settings to Settings. → Annexes → Application management → Game Turbo → Warehouse → Clear the data.

💡

If you need to temporarily turn off the volume buttons to record video without noise, use an external microphone and activate Do Not Disturb mode with an exception for the camera.

Method 2: Use of the ADB-commands (without root, but with PC)

A more advanced method is to disable buttons through ADB (Android Debug Bridge.This doesn't require root rights, but it will require a smartphone to be connected to a computer.The method works on most Xiaomi devices running Android 10+.

First, check if your device supports key layouts.

adb shell getevent -p

In the conclusion, find the lines with KEY_VOLUMEUP, KEY_VOLUMEDOWN and KEY_POWER. If they are, we can continue.

To turn off the volume button, do:

adb shell settings put global volume_rockers_wake 0


adb shell settings put global volume_key_cursor_control 0

To disable the reaction to hold the power button (but not to short press!):

adb shell settings put global power_key_long_press_action 0

These commands don't remove the button handlers completely, they just change their behavior, so to get it back, replace the 0 with 1 commands above.

⚠️ Attention: Teams ADB They reset when you restart the device, and to make the changes permanent, you need to create an auto-start script or use applications like Tasker to re-apply the settings when you start the system.

Method 3: Applications for button reassignment (with or without root)

If standard methods don't work, you can use third-party applications, some of which are root-free but with limitations, others require full access to the system.

The best button management apps:

• 🔧 Button Mapper (requires) ADB or root: allows you to reassign any physical buttons, including disabling their functions; supports the creation of user actions (for example, launching applications or gestures).
• 🎛️ Key Mapper (works through the ADB): It's a simple interface to turn off or change the behavior of the buttons. MIUI 12-14.
• 🛠️ Tasker + Plugin “AutoInput” (without root): allows you to create rules to ignore button presses in certain conditions (for example, only in games).
• 🔇 Volume Unlock (volume buttons only): Disables volume change locks in certain applications.

Example of settings in Button Mapper:

1. Install the app from Google Play or XDA.
2. Provide access through ADB (The application will show the command to enter).
3. Select the button you want to disable (such as Volume Up).
4. Press Add Action. → Do Nothing.
5. Save the settings and restart the device.

More powerful tools are available for root-right users, such as the Xposed Framework with GravityBox, which allow you to completely redefine the behavior of buttons at the system level, but require deep knowledge and can disrupt stability. MIUI.

Method 4: Edit system files (for power users only)

This method is only suitable for root-access devices and involves direct access to system files. Wrong actions can lead to a device “brick”, so only perform them if you are confident in your skills.

Buttons in Android are managed through files in the directory /system/usr/keylayout/. To disable the button, you need to find the corresponding file (usually Generic.kl or {model_name}.kl) and edit it.

Example to turn off the volume button:

1. with the help of Root Explorer or ADB open the file /system/usr/keylayout/Generic.kl.
2. Find the key line 115 VOLUME_UP (number).
3. Replace her with #key. 115 VOLUME_UP (Add # to the beginning).
4. Save the file and restart the device.

For the power button, look for the line with KEY_POWER (key 116). Disabling this button without an alternative way to turn on the smartphone is extremely dangerous!

💡

Editing system files can lead to a cyclic bootloop if you get the syntax wrong. Always back up the original file before you change it!

After editing, check the functionality of the buttons with the command:

adb shell getevent -l

If the button is no longer displayed in the log, it is successfully disabled.

Method 5: Alternative solutions (if you can’t turn off the buttons)

If none of the above methods worked, consider alternative approaches:

• 🛡️ Button lock cases: Some cases (like the Spigen Tough Armor) have thickened edges that physically prevent you from pressing buttons.
• 🔄 Reassign buttons: instead of turning them off, assign them rarely used functions. For example, the volume button can be made by calling the voice assistant.
• 🔧 Repair or replace buttons: if the problem is mechanical failure, contact the service center. on Xiaomi, replacing the power button is worth it ~1500-2500 ₽ (model-wise).
• 📱 Use of gestures: activate full-screen gestures in Settings → Screen. → Full screen mode. This will reduce the need for physical buttons.
• 🔌 USB-OTG Adapters: for emergency control, you can connect an external keyboard through USB-C and use her buttons.

If you’re experimenting with switching off buttons due to a breakdown, consider that on some Xiaomi models (like the Redmi Note 10 Pro), the power button is integrated with the fingerprint sensor, which can block the scanner, which will make it impossible to unlock the device.

Frequent Mistakes and How to Avoid Them

When you're working with physical buttons, you often have some common problems, and here are the most common ones and the ways you can solve them:

If you have lost access to your device after disabling the buttons, try the following steps to restore:

1. Connect your smartphone to your PC and check if it is detected in fastboot (fastboot devices).
2. If yes, run the original firmware through the Mi Flash Tool.
3. If not, try to pinch the Power combination. + Volume Down on the 10-15 second-on-second forced reboot.
4. In extreme cases, contact the service center with an indication of the problem (“does not respond to the power button”).
