What to do if the buttons on the Xiaomi phone do not work: from reboot to disassemble

Buttons on Xiaomi’s smartphone are the main control tool, and their failure can turn even the flagship device into a useless “brick.” The problem is found on both budget Redmi and POCO, and on the top Xiaomi 13/14, with causes ranging from software failure to physical wear. In 60% of cases, the malfunction can be fixed on its own without resorting to the help of a service center. But it is important to correctly diagnose the source of the problem: whether it is contamination of contacts, or damage to the plume, or a firmware failure after an update.

In this article, we will discuss step-by-step recovery methods, from basic reboot to disassembling the case and cleaning the buttons. Particular attention will be paid to models with a non-shatterable body (for example, Xiaomi 12T or Redmi Note 11 Pro+), where the risk of damage to the device when self-repair is maximum, and you will learn how to temporarily control the phone without physical buttons while repairing.

1. Diagnostics: which button does not work and under what conditions

Before you rush to disassemble the phone, determine the nature of the malfunction. Buttons on Xiaomi can behave in different ways:

• 🔘 Complete failure – the button does not physically press or respond to presses.
• 🔄 Sticking – the button works on its own or requires several clicks.
• ⚡ Selective work – the button only functions in certain applications (for example, volume control works in the player, but not in the settings).
• 🌡️ Temperature-dependent button stops working after phone overheats or cools.

Run the test:

1. Try pressing the button in different scenarios: on a locked screen, on the menu, during a call.
2. Check the reaction to a long press (for example, the power button should call the off menu).
3. Connect your phone to your PC and try to manage the buttons via ADB (instruction below).

If the button doesn't respond only under certain conditions (such as low battery power), the problem is more software-based, and if it doesn't work at all, prepare for mechanical repairs.

2. Software recovery methods (without disassembly)

In 40% of cases, the buttons stop working due to firmware failures, application conflicts, or system errors.

Forced reset

If the phone does not respond to the power button, but the screen turns on (for example, when connecting a charge), perform a forced reboot:

• 📱 Hold the power button. + volume increase of 10-15 seconds.
• 🔄 In some models (for example, POCO F3) power-sharing + volume-reducing.
• ⚠️ If the phone is discharged, first connect it to charge for 10-15 minutes.

2.2 Resetting settings via Recovery

If the reboot didn’t help, try resetting to factory settings via Recovery mode:

1. Turn off your phone (forced if you don’t respond to the button).
2. Press the power button + increase the volume before the Mi logo appears.
3. In the Recovery menu, select Wipe Data → Wipe All Data (manage by volume buttons, confirm by power button).

Important: this method will remove all data from the phone. If the volume buttons don't work, move on to the next method.

Control via ADB (if the buttons do not work at all)

If the physical buttons fail completely, but the phone turns on, connect it to your PC and use ADB (Android Debug Bridge) to emulate the clicks:

adb shell input keyevent KEYCODE_POWER # Emulation of power button pressing


adb shell input keyevent KEYCODE_VOLUME_UP # Emulation of volume increase

A list of all the keys can be found in the Android documentation. ADB need to:

• 🖥️ Installed drivers Xiaomi and ADB Tools on PC.
• 🔌 Included debugging by USB (If not activated in advance, this method will not work).

💡

If USB debugging has been disabled and the buttons are not working, only a service center or disassembly remains to enable Fastboot mode manually.

3. Mechanical cleaning of buttons (for collapsible models)

If software methods didn’t work, the problem is likely to be contamination of the contacts or wear of the button. On models with a removable back cover (for example, Redmi 4X, Redmi Note 5) you can try to clean the buttons yourself.

Disassembly of the shell

You'll need:

• 🔧 Plastic mediator or guitar mediator.
• 🧲 Magnetic screwdriver (cross, size) PH00).
• 🧴 Isopropyl alcohol (90%+) and cotton-stick.

Procedure:

1. Turn off the phone and remove it. SIM-memory-card.
2. Put the mediator on the back cover, starting at the corners (on Xiaomi there are usually gaps near the headphone jack).
3. Unscrew the screws that fix the metal plate over the battery.
4. Carefully disconnect the battery plume (do not pull the wires!).

Cleaning the buttons

Buttons on Xiaomi are mechanical microswitches that eventually get clogged with dust or oxidized.

• 🧽 Moisten the cotton swab in isopropyl alcohol and wipe the button contacts (do not pour the alcohol inside!).
• 🔍 Check the integrity of the rubber pads under the buttons - if they are torn, the button will "fall over».
• 🔄 Press the button manually several times to dissolve the contaminants.

After cleaning, let the phone dry for 10-15 minutes before assembly.

4.Temporary Solutions: How to Use a Phone Without Buttons

If repairs are delayed and the phone is urgently needed, use alternative management methods:

For models with an infrared port (for example, Redmi Note 10 Pro) you can use the remote from the TV, having programmed it to emulate buttons through the Mi Remote application.

💡

MIUI 12+ has a hidden function called “Assistive Ball” that duplicates physical buttons. It is enabled in Settings → Special Features → Floating Button.

5.When a service center is required: signs of serious breakdown

Not all button malfunctions can be fixed at home.

• 💥 The button broke after falling or getting moisture - several components could be damaged at the same time.
• 🔌 The phone does not turn on at all, even after connecting to charging.
• 🛠️ The button is soldered to the motherboard (relevant for 2020 models)+ For example, the Xiaomi Mi 11).
• ⚡ Artifacts appear on the screen or the phone spontaneously reboots when you press a button.

The cost of repairing buttons in service centers:

• 🔧 Replacement of the power button: 1,200–2,500 ₽ (model-wise).
• 🔊 Replacement of the plume with volume buttons: 1,800–3,500 ₽.
• 💧 Cleaning after moisture: from 3 000 ₽ (It involves the diagnosis of other components).

⚠️ Note: On Xiaomi models with amoleed screens (for example, Xiaomi 13 Ultra), self-disassembly can lead to damage to the display due to fragile plumes. Official services for such phones use special devices for safe opening.

6.Prevention: How to prolong the life of buttons on Xiaomi

Buttons on Xiaomi smartphones are designed for 50,000-100,000 clicks, but this resource can be shortened or extended depending on the operation.

• 🧼 Clean the connectors with compressed air regularly (1 every 3 months).
• 🚫 Avoid strong presses – buttons on Xiaomi are triggered by a light touch.
• 🌧️ Do not use your phone in wet conditions (such as in the bathroom) – condensate oxidizes the contacts.
• 🔋 Watch the charge level: at a discharge below 10%, some models lock buttons to save energy.

On newer models (such as the Xiaomi 14), the buttons are protected from dust by a membrane, but this does not save from mechanical damage. If you drop your phone often, consider cases with reinforced bumpers (for example, from Spigen or Ringke).
