Xiaomi Redmi 8 screen does not respond to touch: reasons and solutions

The Xiaomi Redmi 8 touchscreen is no longer responsive to touch? The problem is familiar to many owners of this budget smartphone, especially after 2-3 years of use. In some cases, the display “gluts” partially (the top or bottom part does not work), in others it completely ignores touch, although the image remains clear. The causes can be hidden in software failures and physical damage.

In this article, we'll look at all the ways you can restore the screen, from the simple (reboot, clean the cache) to the radical (replace the display module). Importantly, some methods require disassembling the device, so if you're not sure about your skills, you'd better go to the service center. But first try solutions that do not require opening the case.

1.Reboot and check basic functions

Start with the obvious, forced reboot, and sometimes the sensor freezes because of a temporary failure in the MIUI operating system.

• 🔄 Press the Power button for 10-15 seconds until the phone turns off and starts to boot again.
• 🔋 If the screen is not fully responsive, connect the charger – perhaps the battery has discharged to zero, and the smartphone does not show signs of life.
• 📱 Try to connect Redmi 8 to your computer. USB. If the PC detects the device, the problem is not exactly the hardware».

After restarting, check if the sensor is operating in Safe Mode.

1. Press the Power button and hold it until the turn off menu appears.
2. Press and hold the item "Switch off power (or turn off)" until the prompt appears to go to safe mode.
3. Confirm the action.

If the sensor is working normally in Safe Mode, one of the installed applications is to blame: Uninstall the recently added programs or reset the settings (more on this below).

2.Cache cleaning and settings reset

A clogged system cache or update conflict can cause the sensor to freeze. Try clearing temporary files via Recovery Mode:

• 🔧 Turn off the phone.
• 🔘 Press both Power and Volume up at the same time before the Mi logo appears.
• 📱 In the Recovery menu, select Wipe & Reset. → Wipe Cache (control is carried out by volume and power buttons).
• 🔄 After cleaning, restart the device.

If this doesn’t help, reset to factory settings (all data will be deleted!):

1. In the Recovery menu, select Wipe & Reset → Wipe All Data.
2. Confirm the action.
3. After restarting, set your phone as new.

3. Physical damage check

If the software methods didn't work, the problem could be mechanical damage.

• 💥 Cracks or chips (even microscopic ones).
• 🌡️ Screen bloating (if the display "steps away" from the body).
• 💧 traces of moisture under the glass or in connectors (oxidation of contacts).
• 🔌 Bad fit of the plume (if the phone fell).

On Xiaomi Redmi 8, a common problem is that the touch layer is detached from the matrix due to cheap glue or overheating. If the screen only responds to strong presses or clicks in certain areas, you will likely need to replace the display module.

For diagnosis:

1. Hold the phone to bright light at an angle - so you can see microcracks better.
2. Try to press carefully on different parts of the screen, and if the sensor starts to work, the problem is in the plume or contacts.
3. Check if the screen is “playing” when pressed (this is a sign of detachment).

4.Diagnostics via ADB (for advanced users)

If the screen is partially working (e.g., it only responds to swipes, but not to touch), you can try to control the phone via ADB (Android Debug Bridge), which will help save data or perform a reset if the sensor does not allow you to do it manually.

For this:

1. Install. ADB-pc-tool.
2. Connect Redmi 8 to your computer via USB and enable USB Debugging (if the screen reacts at all).
3. Open the command line in the adb folder and type:

adb devices

(Your device should be coming up.)

adb shell input tap x y

(Replace x and y with touch coordinates, such as adb shell input tap 500.)

If the commands are executed but the screen is not responding, the problem is precisely in the hardware (sensor or plume).

1. Turn off the phone.

2. Press Power + Loudness down to enter the Fastboot.

3. Connect to your PC and type in the command fastboot oem enable-adb (not working on all models).-->

5. Replacement of touch glass or display module

If all previous methods failed, all that remains is to repair or replace the screen. On the Xiaomi Redmi 8, the display module consists of three parts:

• 📺 Matrix (LCD) — picture-responsible.
• 👆 Touch Panel – Records touches.
• 🔌 The plume - connects the screen with the motherboard.

In most cases, it is the touch glass or the plume that fails, and you can replace them yourself, but this requires accuracy and tools:

• 🛠️ Necessary tools: plastic blades, suction cup, hair dryer (for softening the glue), screwdriver T3.
• 📦 Parts: Original display module for Redmi 8 (article begins with MDY09).
• 📹 Recommendation: Before disassembling, check the video guide specifically for your model (e.g., on YouTube for “Redmi 8 display replacement»).

⚠️ Warning: When you replace the screen with Xiaomi Redmi 8, it is easy to damage the flexible battery cable or antenna contacts. If you have never disassembled your phones, you should trust the professionals - the cost of repairing the service (1,500-3000) ₽) often below the error price (burnt motherboard).

• 🖱️ Mouse by mouse. USB-OTG: Connect. USB-mouse-adapter OTG. V MIUI cursor will appear automatically.
• 🎮 Gamepad: Some gamepads (e.g. Xbox or DualShock) are supported in mode HID.

2. Connect the wired mouse.
3. The cursor should appear in 5-10 seconds.

This will help you copy the data or at least take an important call while the phone is being repaired.

7. When to contact the service center

Self-repair is justified if you are confident in your skills, otherwise it is better to consult a specialist.

• 🔥 The screen stopped working after falling or getting moisture.
• 🔌 The phone doesn’t turn on at all (no vibrations).
• 📵 Sensor reacts chaoticly (independent clicks, swipes).
• 🔋 Battery discharges quickly after changing the screen (sign of short circuit).

Cost of repair in the service:

Before the service visit:

1. Check if they work with your model (Redmi 8 has several modifications: M1908C3IC, M1908C3IE, etc.).
2. Ask if you have a warranty for repairs (at least 3 months).
3. If the phone is warranty, contact the official Xiaomi service - self-repair cancels warranty obligations.

If the Redmi 8 was purchased less than a year ago and the problem is not your fault (for example, a factory plume defect), the repairs should be free of charge under warranty.
