Xiaomi screen does not respond to touch: reasons and solutions

A touchscreen that suddenly stopped responding to touch is one of the most annoying malfunctions of a smartphone, especially if it happened on a Xiaomi device, where a combination of software and hardware can make it difficult to diagnose. In some cases, the problem is solved in a minute, in others, it requires the intervention of a service center. This article will help you understand why the Xiaomi screen does not respond to touch, and what to do about it.

We'll look at all the possible causes, from the simple freeze of the system to damage to the display plume, and we'll give you step-by-step instructions for each situation. It's important to understand that the algorithm of actions depends on whether the screen responds at least partially (for example, to gestures or certain zones), is completely "dead", or the problem manifests itself after falling / getting moisture. Some solutions will be suitable even for devices with broken glass, if the sensor itself remains intact.

Before you panic and carry your phone for repair, try going through our checklist. In 70% of cases, the malfunction is fixed without disassembling the case - it's enough to reset the settings or update the firmware. But there are also pitfalls: for example, on Redmi Note 10 Pro models or on the Redmi Note 10 Pro models. POCO X3 Pro often encounters sensor failure due to shell conflict MIUI 14. On this and other nuances.

1.The first steps: what to do before a deep diagnosis

If the screen is no longer responsive to touch, start with basic actions. They require no special skills and take minimal time.

Reboot the device forcefully. On most Xiaomi models, this is done by pressing the Power button. + Increase volume by 10-15 seconds until the Mi logo appears on some devices (e.g. Redmi). 9A) Just hold the power button for 20 to 30 seconds, and if the phone doesn't respond to that, plug it into charging for 10 to 15 minutes, then try again.

Check if the screen is working at all:

• 🔦 Lighting is on, but touches are not recorded?
• 📱 The screen is completely black, but the phone vibrates when you press the buttons?
• 🔄 Partially responds to gestures (e.g., swipe to unlock)?

The answers to these questions will narrow down the possible causes, such as if there is a backlight but the touches are ignored, the problem is more software-based, and if the screen is not showing signs of life, it could be a hardware malfunction (steel, controller, battery).

Turn off all accessories. Sometimes sensor glitches are caused by magnet cases, wireless charges, or even headphones connected via Bluetooth. Make sure that the phone is not affected by external interference. Also try to clean the charging connector - accumulated dust or moisture can affect the operation of the sensor (especially on models with Quick Charge function).

2. Software failures: how to return to work without repair

In 60 percent of cases, a sensor that's broken is a software conflict, so let's look at the most effective ways to reanimate the screen.

Reset your settings via Recovery. If your phone turns on but the screen doesn't respond, try resetting to factory settings via Recovery mode.

1. Turn off the device (forced if necessary).
2. Press Power + Volume Up until the Recovery menu appears.
3. Use the volume buttons for navigation and the power button to select the Wipe Data (or Factory Reset) item.
4. Confirm the action and wait for the process to be completed.

⚠️ Note: This method will delete all data from the device, including photos and apps. If the phone was enabled sync with Mi Account, some of the data (contacts, notes) can be restored after logging into the account.

Update or roll back firmware if the sensor stopped working after the update MIUI, The problem may be in the raw version of the software:

• 📲 Update to the latest stable version via Settings → The phone. → Update the system (if the screen reacts at least somehow).
• 🔙 Reverse to the previous firmware via Fastboot (you will need a computer and the Mi Flash Tool program).
• 🛠️ Install custom firmware (e.g. Pixel Experience) if official versions are bugged.

On models POCO F3 Xiaomi 11T Pro often helps rollback with MIUI 14 on MIUI 13 – New versions have bugs with sensor drivers.

Sensor calibration: Sometimes the screen doesn't recognize touch correctly because of a miscalibration setting, to reset it.

Dial in the dialer: ##6484##


Select "Test Touch" and follow the instructions on the screen.

If this code doesn't work, try #4636## → Testing → Touch Screen Test on some models (e.g. Redmi) 9C) The sensor calibration is only available through the engineering menu that is opened by the command ##3644633##.

3. Hardware causes: when the "iron" is to blame

If the software methods didn't work, the problem is probably hardware, and let's look at the typical hardware malfunctions and their signs.

Display plume damage. This is the most common hardware failure, especially after falls. The plume connects the screen to the motherboard, and when it is disconnected or detonated, the sensor stops working (the backlight may remain on).

• 📵 The screen lights up but does not respond to touch.
• 🔄 Sometimes the sensor “wakes up” at a certain tilt of the phone (this indicates poor contact).
• 🎨 Colored stripes or artifacts appear on the screen.

The solution is to replace the plume in the service center, and it's hard to do it yourself: you need a complete disassembly of the device and a soldering hair dryer, and the cost of repairs is from 1,500 to 4,000 rubles depending on the model.

Sensor controller malfunction: The touch processing chip may fail due to overheating, short circuit or factory defect.

• 🔥 The phone is very warm in the upper part of the screen.
• 📱 The sensor works in “snippets” or registers “ghost” touches.
• 🔌 The problem appeared after getting moisture or charging with an unoriginal cable.

In this case, too, repairs are needed: the controller is either soldered or replaced with the entire display module. On Xiaomi 12 and newer models, the controller is often soldered into the motherboard, which makes repairs more difficult.

Moisture or corrosion: If the phone falls into water or is in a damp environment, oxidation of the contacts can cause the sensor to fail.

• 💧 The screen shows stains or stains (even if they are disappeared).
• 🔋 The phone is quickly discharged or not charged.
• 📶 Network or Wi-Fi is not working well (moisture often affects multiple components at the same time).

⚠️ Warning: If the moisture has recently been injected (within 48 hours), don't turn your phone on or charge it! Put it in a silica gel (or rice) bag for a day, then try to turn it on. If more time has passed, carry it to the service, as corrosion could damage the board.

4. Features of repair on popular Xiaomi models

Some Xiaomi smartphones have unique pains associated with screen design or firmware.

For example, the Redmi Note 10 Pro often encounters a bug when after an update. MIUI The sensor stops responding to touches at the bottom of the screen, and this is due to a conflict between the touchscreen drivers and the new shell version, and the solution is to roll back to stable firmware or manual firmware through Fastboot, cleaning the persist partition.

Nana POCO X3 The problem is usually related to the overheating of the Snapdragon 860 chipset. When you are under intense load (games, benchmarks), the phone heats up and the sensor controller starts to glitches## → Battery → shut down USB and enable background restriction).

💡

If you have Xiaomi Mi 11 or newer, avoid disassembling yourself - the screen plume is attached to fragile latches that are easy to break.

5.Temporary Solutions: How to Use a Phone Without a Sensor

If the screen is not responding, but the phone is turning on, you can temporarily control it with external devices, which will help save data or wait for repairs.

Connecting the mouse to OTG. Most of Xiaomi smartphones support the work with USB-mouse-adapter OTG. How to do this:

1. Buy an adapter. USB-C/Micro-USB → USB-A (depending on the phone connector).
2. Connect a wired or wireless mouse (if wireless, connect a USB-dongle first).
3. The cursor will appear on the screen and you will be able to control the phone like a computer.

This solution works even on a locked screen: swipe your mouse up to unlock the device, then go to Settings. → System system → Special facilities → Control the pointer and adjust the sensitivity.

Remote control via Mi Remote or TeamViewer, if the phone was on USB-debugging and it's connected to the same Wi-Fi network as the computer, you can control it through ADB Or TeamViewer QuickSupport:

1. Install the program ADB (Android Debug Bridge). on PC


2 Connect the phone to the computer via USB.




3. Enter the command:




adb shell input tap x y




(where x and y are the touch coordinates on the screen).

To simplify, you can use Scrcpy, which duplicates the phone screen on the computer and allows you to control it from the keyboard.

Google Assistant, if you have a voice assistant set up on your phone, you can try to control it. Say, "Okay, Google," then you can:

• 📞 «Call your mom (for calls).
• 📧 «Open Gmail (to launch applications).
• 🔍 «Find the settings" (to navigate the menu).

⚠️ Warning: Voice Assistant will not be able to unlock the screen unless Smart Lock is configured (automatic unlock in trusted locations).

6.When to contact the service: signs of a serious breakdown

Some symptoms clearly indicate that the phone needs professional repair, and you should not postpone a visit to the service if:

The screen is completely black, but the phone makes sounds.

• 🔋 Failure to illuminate (LED-tapes) with the operating sensor.
• 📱 Damage to a graphics chipset or video chip on the motherboard.
• 🔌 Problems with the power of the screen (for example, the voltage stabilizer burned).

And in this case, you need to have a multimeter or an oscilloscope to determine if the power is going to the display, and you can't do that on your own.

The sensor is sniffing or registering false touches, which is a typical sign.

• 🔥 Overheating of the sensor controller (often on the POCO F3 Xiaomi 11T).
• 📉 Screen damage from the inside (e.g. cracks on the inside of the digitizer).
• 🛠️ Incorrect firmware (if the problem occurred after the update).

If the flashing did not help, most likely, you will need to replace the display module or soldering the controller.

If the screen is not responding and the device is not showing signs of life (no vibration, no charge indicator), the reasons may be as follows:

• 🔋 Full battery discharge (sometimes a "push" is required by a high-current charger).
• 📱 Short circuit on the motherboard (for example, after moisture hits).
• 🔌 Power controller damage (frequent problem on Redmi) 8/9 fall-out).

In this case, do not try to charge the phone, it can aggravate the damage, it is better to bring it to the service immediately for diagnosis.

💡

If the phone fell, wet or subjected to mechanical stress, any attempts to repair yourself (disassembly, warm-up hair dryer, “knocking on the body”) can lead to irreversible damage to the board.

7.How to avoid sensor problems in the future

To make Xiaomi’s screen last longer, follow the simple guidelines:

Use quality accessories.

• 🔌 Charge your phone with original cables and power supplies (or certified Quick Charge-enabled counterparts).
• 📱 Avoid cheap cases with metal inserts – they can interfere with the sensor.
• 🛡️ Stick a protective glass (preferably with oleophobic coating) – it reduces the load on the sensor.

Keep an eye on the updates.

• 📲 Update regularly MIUI, Do not install the beta version unless you are sure of its stability.
• 🔄 After major updates (e.g., with the MIUI 13 on MIUI 14) check the sensor in the Settings menu → The phone. → Diagnostics.
• 🛠️ If there are glitches after the update, roll back to the previous version through Recovery.

Keep your phone away from extreme conditions.

• 🌡️ Do not leave the device in the sun or near heat sources (e.g., on a car torpedo).
• 💧 Avoid high humidity (such as in the bathroom while showering).
• 📦 When transporting, put your phone in a separate compartment of your backpack to avoid pressure on the screen.

💡

In the models with AMOLED-screens (for example, Xiaomi 12 Pro) avoid displaying static images for a long time – this can lead to “burnout” of the matrix and sensor malfunctions.
