Xiaomi button: how to open hidden functions and unlock the device

Why Xiaomi buttons may not work as expected

Xiaomi devices, from smartphones to smartwatches, are equipped with physical buttons that perform not only basic functions (on, volume control), but also hidden commands. For example, a key combination can trigger recovery mode, reset settings, or even unlock the bootloader. However, many users are faced with the fact that the buttons either do not respond or behave unexpectedly, the reasons for this are diverse, from software failures to mechanical damage.

This is especially relevant for owners of devices with custom buttons, such as the Xiaomi Mi Band or Redmi Watch, where a single physical key is responsible for several actions. In this article, we will analyze all possible scenarios: how to open hidden functions through buttons, what to do if they do not work, and how to avoid typical errors when manipulating hardware controls.

It is important to understand that improper use of button combinations (for example, prolonged retention of Power + Volume Up) can lead to irreversible consequences - from data loss to "bricking" the device.

Basic button combinations for Xiaomi smartphones

Most Xiaomi, Redmi and POCO smartphones use three physical buttons: Power (on/lock), Volume Up (volume+), and Volume Down (volume-). These combinations allow you to perform system actions without access to the screen.

  • πŸ”„ Reboot: Hold the Power for 10-15 seconds (if the device is getting stuck).
  • πŸ“± Recovery Mode: Turn off the phone, then press the Power + Volume Up before the Mi logo appears.
  • πŸ€– Fastboot Mode: Turn off the device, press the Power + Volume Down.
  • πŸ”’ Emergency call: Press Power 5 times on locked screen (not working on all models).

On some models (such as the Xiaomi 12 Pro or Redmi Note 11), the Power + Volume Up + Volume Down combination can simultaneously trigger a diagnostic mode where information about the hardware is displayed.

If the Power button doesn’t respond to a short press, try connecting the charger – sometimes the smartphone unlocks automatically when connected to the network.

Please note: on devices with AMOLED-With screens (e.g. Xiaomi 13 Ultra), long-term button retention can activate Always-On Display even when it’s off.

Hidden button features on smart watches and fitness bracelets Xiaomi

Xiaomi smartwatches and trackers (Mi Band, Redmi Watch, Xiaomi Watch series) have a minimalist design with one or two buttons, but their functionality is much wider.

  • πŸƒ Start the workout: A short press β†’ sport selection.
  • πŸ” Find the phone: Hold the button for 3 seconds (if the watch is connected to the smartphone).
  • πŸ”‹ Show the charge level: Double press (on some firmware).
  • πŸ”„ Reset the device: Hold 10+ seconds (if the clock hangs).

On the Xiaomi Watch S1 with two buttons, the left is responsible for returning to the menu, and the right is responsible for launching applications. Double pressing the right button opens the list of recent notifications, and holding the left one turns on the Do Not Disturb mode.

How to reset Mi Band to factory settings?
Hold the button for 20-30 seconds until the vibration and Mi logo appear. After that, all data will be erased, including pairs with the phone.

Important: On some models (such as the Mi Band 6), long-term retention of the button in the settings menu can activate a hidden engineering mode where display, accelerometer and Bluetooth tests are available.

What to do if the buttons on Xiaomi do not work

If the physical buttons stopped responding, the reasons could be both software and hardware.

  1. Check for moisture or dirt under the buttons, and gently wipe them with a cotton swab dipped in alcohol (don’t pour the liquid directly onto the device!).
  2. Restart your device via the menu (if the screen is running) or using the Power + Volume Up combination.
  3. Update your firmware. Sometimes button bugs get fixed in newer versions of MIUI. Check for updates in Settings β†’ About Phone β†’ System Update.
  4. Reset to factory settings (if the problem is not hardware). To do this, go to Settings β†’ Additional β†’ Recovery and Reset.

If the buttons don't work after falling or getting moisture, there's probably a break in the contacts or oxidation of the board, and if you do, you'll only need repairs at the service center, and don't try to disassemble the device yourself, because that could lead to a loss of warranty.

On devices with removable battery (for example, old models of Redmi) the power button malfunction can be temporarily bypassed by connecting the charger - the phone will turn on automatically.

How to unlock Xiaomi if the power button doesn’t work

If the Power button is broken but the device is on, you can unlock it in several ways:

  • πŸ”Œ Connect charging: On some models, the screen is activated when connected to the network.
  • πŸ“ž Call your phone from another device – an incoming call can wake up the display.
  • πŸ”Š Use voice assistant: Say β€œOK Google” or β€œHi Siri” (if configured).
  • πŸ–₯️ Connect to the PC through ADB and execute the command: adb shell input keyevent 26 (this simulates clicking the switch button).

If the phone is turned off and does not respond to charging, try a hardware reset via a combination of volume buttons. For example, on Redmi 9, press Volume Up + Volume Down for 10-15 seconds - this can force the device to start.

On NFC devices (such as Xiaomi 13), you can try unlocking the screen by attaching another smartphone with NFC enabled to it – if the Smart Unlock feature is configured.

Resetting settings through buttons: step-by-step instructions

If the device is not turned on or locked and other methods do not help, then hard reset via Recovery mode will delete all data, so use it only as a last resort.

Instructions for smartphones:

  1. Turn off the device (if it is on, hold the Power for 10+ seconds).
  2. Press the Power + Volume Up and hold until the Mi logo appears.
  3. In the Recovery menu, select Wipe Data (use volume buttons for navigation, Power buttons for confirmation).
  4. Confirm the reset by selecting Yes.
  5. After completion, select Reboot.

For Xiaomi smartwatches (such as the Mi Watch):

  1. Turn off the clock (hold the 10 seconds button).
  2. Connect to the charger.
  3. Hold the button for 20-30 seconds until the reset begins.

Recovery removes all data, including accounts, photos and apps. If the device was linked to a Mi Account, after the reset, you will need to enter a login and password to unlock (FRP protection).

Some models (such as the POCO F3) may require the bootloader to be unlocked via Fastboot after the reset.

Frequent errors when working with buttons and how to avoid them

Many users make common mistakes that lead to data loss or breakdowns.

  • ⚑ Pressing buttons with force - this can break the mechanism or damage the plume.
  • πŸ’¦ Clean buttons with water or aggressive liquids (such as acetone).
  • πŸ”§ Disassemble the device without experience, especially if it is guaranteed.
  • πŸ“± Use unofficial firmware without backup data.

Also common is interrupting the reset process, so if you start resetting through Recovery, never turn the device off until the process is complete, which can damage system files.

πŸ’‘

Before any button manipulations, back up your data via Settings β†’ Additional β†’ Backup or Mi Cloud.

Another nuance: on devices with an infrared port (for example, Redmi Note 10), prolonged retention of the Power button can accidentally activate the remote control. If this interferes, turn off the function in Settings β†’ Connections β†’ Remote.

Can I replace the button on Xiaomi by myself?
Theoretically, yes, but it requires experience in soldering and disassembling equipment. Most models need special tools (screen sucker, tweezers, hair dryers). If you are not sure about your skills, you should contact a service center. The cost of replacing a button in official Xiaomi services usually does not exceed 1-2 thousand rubles.
Why does the phone require a password from the Mi Account after resetting through the buttons?
This is FRP (Factory Reset Protection) protection feature, which is activated if the device was tied to a Mi Account. To unlock the phone, you need to enter the username and password from this account. If you forget them, restore access through account.xiaomi.com.
How to open the engineering menu through the buttons?
On most Xiaomi smartphones, the engineering menu opens with the code ##4636## in the Phone app. This menu does not open through the buttons, but on some models (for example, Redmi 5), the Power + Volume Up + Volume Down combination can show diagnostic information.
What if the volume button works and the switch on button does not?
In this case, try to connect the device to charge - sometimes the phone turns on automatically. If the screen does not respond, you can try to start the ADB through the computer and send an on command (see section above).
How to turn off the random pressing of buttons in your pocket?
Xiaomi has a button lock feature. To enable it, go to Settings β†’ Lock screen β†’ Additional β†’ Lock buttons. You can also activate In-pocket mode in Settings β†’ Display β†’ Mode in your pocket.
