The touchscreen on Xiaomi smartphones is one of the most vulnerable elements, which often fails after falls, getting moisture or simply because of wear, POCO or Mi has ceased to respond adequately to touch - do not rush to carry it to the service: 60% In some cases, the problem can be solved independently. 10-30 In this article, we'll look at all the possible causes, from software failures to physical damage, and give you step-by-step instructions with photos and videos to get the touchscreen back on track.
The peculiarity of Xiaomi smartphones is that their sensors often suffer not only from mechanical damage, but also from firmware errors (especially after updates). MIUI). For example, the owners of Redmi Note 10 Pro and POCO X3 Pro massively complained about the βfloatingβ sensor after updating to MIUI 14. We have collected relevant solutions for all models 2019-2026 year, including budget Redmi A2 and flagship Xiaomi 14 Ultra.
Before you start repairing, determine the nature of the malfunction:
- πΉ The sensor does not respond to touch (there is a black screen or image, but touch is ignored)
- πΉ The screen presses buttons ("ghost touches")
- πΉ Part of the screen is not working (for example, the top 2 cm is not pressed)
- πΉ The sensor is delayed or triggered again.
- πΉ After the fall, there were divorces or cracks on the display
Each of these symptoms requires different approaches, from a simple reboot to a touchscreen replacement, starting with the simplest and safest methods.
1.Reboot and check for program failures
In 30 percent of cases, a broken sensor on Xiaomi is a temporary system glitch that is solved by a normal reboot.
If the screen is not fully responsive, but the phone is on (lights are on, notifications are heard), try a forced reboot:
- Press the power button. + Volume up on 10-15 seconds.
- After the vibration and the Mi logo appears, release the buttons.
- If the phone hasnβt rebooted, plug it into charging and try again.
If the sensor is partially working (you can unlock your phone), follow these steps:
- π± Go to Settings. β The phone. β Update the system and check the relevance of the firmware.
- π Make a soft reset: Settings β Additionally. β Resetting settings β Reset all settings (does not delete files!).
- π οΈ Run screen diagnostics: dial in the phone application ##6484## (for display test) or ##4636## (general diagnostics).
Important! If the sensor is running after the reboot, but after a while the problem has returned, it's a sign of a malfunction of the plume or the touchscreen controller, in which case only disassembling the phone will help.
Calibration of the sensor: step-by-step instruction
Incorrect calibration is a common reason why the sensor on Xiaomi does not respond well to touch. AMOLED-screens (Xiaomi) 12T, Redmi K50), where the coordinates of touches shift over time.
Official calibration menu in MIUI No, but there are two working ways:
Method 1: Engineering menu (for advanced)
- Open the Phone app and dial ##36446337##.
- Go to the Touch Screen section (or TP Calibration).
- Press Calibrate and follow the instructions on the screen (usually touch the crosses in the corners of the display).
- Save the settings and restart the phone.
Method 2: Through third-party applications
If the engineering menu is not available, install from Google Play:
- π² Touchscreen Calibration (Simple Interface, Suitable for Beginners)
- π² Screen Touch Test (checks areas of a broken sensor)
Battery charge > 50%|Turn off all covers and windows.|Connect your phone to charge (for stability)|Close all background applications-->
β οΈ Note: If after calibration the sensor becomes worse (for example, touch has shifted), immediately reset the settings through Settings. β System system β Reset: Some calibration applications may conflict with firmware MIUI.
3. Physical damage check
If the sensor stops working after a fall, impact or moisture hit, it's almost certainly a hardware problem.
Signs of mechanical failure:
- π₯ Cracks or chips on glass (even microcracks can disrupt the sensorβs performance).
- π Condensation under the screen (appears after moisture is ingested).
- π The screen blinks or spontaneously turns off when you press certain areas.
- π Part of the screen does not respond (e.g., lower right corner).
To verify:
- Light a flashlight at an angle on the screen - so you can see microcracks.
- Try pressing different areas of the display with effort (but no fanaticism!). If you press the top left corner, the sensor starts to work, the problem is the disconnected plume.
- Connect your phone to your computer and check if it is defined as a device. MTP. If not, the controller is damaged.
| Symptoms. | Probable cause | Can I correct myself? |
|---|---|---|
| Sensor works, but with a delay | Wear of the sensor layer or plume contamination | Yeah (cleaning, plume replacement) |
| Part of the screen does not respond (top/bottom) | Damage to the flexible plume | Yeah (reconnecting the plume) |
| The screen presses the buttons. | Short circuit in the sensory matrix | No (display replacement required) |
| After the fall, divorces appeared. | Cracking in the matrix or detachment of the sensor | No (replacement only) |
| The sensor is not working, but the image is there. | Faulty touchscreen controller | Partially (microchip soldering) |
β οΈ Warning: If the phone falls into water, don't turn it on or plug it into charging! SIM-map and tray, put the device in a silica gel (or rice) bag for 24 hours.Attempting to turn on wet Xiaomi can short-circuit and total motherboard death.
4.Reset to factory settings
If the software methods didn't work and there was no physical damage, the last chance before repairing it is a hard reset, and it deletes all the data, but it returns the phone to the "clean" state of the firmware.
How to reset if the sensor is not working:
- Turn off the phone.
- Press Power + Volume Up until the Mi logo appears.
- From the Recovery menu, select Wipe Data β Wipe All Data.
- Confirm the action and wait for the completion (5-10 minutes).
If the sensor is partially working, reset via the menu:
- Go to Settings β About the phone β Reset settings.
- Select Delete all data.
- Enter your password (if required) and confirm.
What to do if your phone requires a Mi Account after a reset?
β οΈ Note: On Xiaomi models with Snapdragon 8 Gen 2 chip (e.g. Xiaomi 13, Redmi) K60 Pro) after reset, it may be necessary to flash through the Fastboot if the custom ROM. In this case, contact the service.
5. Replacement of touch glass or display
If all the previous methods didn't work, the hardware is the problem, and 90 percent of the time, you need to replace them.
- π§ Touch glass (if only the top layer cracked, and the matrix is intact).
- πΊ Full display module (if the matrix is damaged or the sensor is not separated from the screen).
- π The touchscreen plume (if the contacts were withdrawn).
