Why Xiaomi’s screen responds poorly to touch and what to do about it
The sensitivity of the touch screen is one of the key characteristics that affect the comfort of using a smartphone. If your Xiaomi has started to ignore light touches, requires a strong push or reacts with a delay, the problem can be in software failures and physical wear of components. AMOLED-screens (e.g. Redmi Note 10 Pro or POCO F3), where the fine glass loses conductivity over time.
In this article, we’ll look at 8 proven ways to get your screen back responsive, from basic Android settings to radical measures like replacing the touchscreen. It’s important to understand that some methods require unlocking the bootloader or root rights, which automatically disqualifies warranties. If your device is still warranty, first contact the Xiaomi service center.
Start with the safest and fastest solutions, and gradually move on to the more complex ones, so if you have a problem after a phone drops or you get moisture, you can go straight to the hardware malfunction section.
1. Calibration of the sensor through the engineering menu
The easiest way to get back sensitive is to recalibrate the touchscreen, which doesn't require root rights, just the standard engineering menu hidden in MIUI firmware. The instructions are suitable for most models, including the Redmi 9, POCO X3 and Mi 11.
How to open the engineering menu:
- 📱 Open the phone app and enter the combination: ##6484##
- 🔧 Select Touch Panel Test (or Touch Screen) from the menu that appears).
- 🎯 Follow the instructions on the screen: you usually need to touch the crosses several times in different areas of the display.
- 🔄 After the test is completed, restart the phone.
If the combination doesn’t work, try the alternative code: ##36446337## (for some versions of MIUI 12/13). On new models (Xiaomi 13, Redmi Note 12), the engineering menu can be blocked – in this case, use applications like MTK Engineering Mode (for MediaTek processors) or Qualcomm Mode.
💡
If the screen reacts worse after calibration, reset settings through Settings → System → Reset settings → Reset sensor settings (not available on all models).
2. Sensitivity setting in the developer
The developer menu has parameters that allow you to increase the response rate of the sensor, so you can activate it.
- Go to Settings. → The phone.
- 7 times click on the MIUI version (you will be notified "You became a developer").
- Return to the main settings menu and open Additional → for developers.
Now find the following options (names may vary depending on the version of MIUI):
- 🔍 Minimum width/touch height – reduce the values by 10-15% more sensitively.
- ⚡ Waiting time for touch – set short (short) or 0.1s.
- 📱 Show touches – turn on to visually track how the screen registers touches.
After the changes, be sure to restart the phone. If the screen becomes too sensitive (responds to random touch), return the values to the standard ones.

3. Update firmware and reset to factory settings
Often sensor problems are caused by software bugs in a particular version of MIUI. For example, MIUI 12.5 for the Redmi Note 8 Pro had a well-known bug with dead zones around the edges of the screen, which was only fixed in patch 12.5.3.0.
Check the relevance of the firmware:
- Open Settings → About the phone → System update.
- If you have an update, install it (preferably via Wi-Fi).
- After the update, perform a soft reset: pinch Power + Volume up for 10 seconds.
If the problem persists, complete the reset (with loss of data):
Make a backup through Settings → Additional → Backup
Remember the Mi Account details (linked to the phone)
Make sure the battery is at least 50% charged.
Out. SIM-card and memory card (if any)
-->
To reset, go to Settings → System → Settings Reset → Delete all data. Some models (POCO M3, Redmi 9A) may require you to enter a password from your Mi Account after the reboot.

4. Check for physical damage and pollution
If the software methods didn't work, the problem could be hardware.
- 💧 Moisture falling under the screen (even if the phone did not sink, condensation from a sharp temperature drop can oxidize the contacts).
- 🔨 Microcracks of glass, invisible to the naked eye, but disrupting the sensor.
- 🧲 Demagnetization of the digitizer (especially important for models with Magnetometer like Xiaomi Mix 4).
- 🔋 Bloating of the battery that presses on the screen from the inside (check if the back cover is swelling).
How to diagnose:
- Light a flashlight at an angle on the screen - microcracks will reflect the light with rainbow stripes.
- Check the screen response to touch in safe mode (press Power, hold off until the option appears). If the screen is working normally in safe mode, the fault is the software.
- Connect your phone to your PC and check if touches are recorded in ADB: adb shell getevent -l (If there is no conclusion with the touch GT_ or TS_ — sensor malfunction).
💡
If the screen only reacts to a strong push, and there are “dead zones” around the edges, this is a 90% hardware problem requiring a touchscreen or plume replacement.
5. Glass or touchscreen replacement: when necessary
If all previous methods failed, it is likely that a replacement of the touch module will be needed, and the table below shows the estimated prices and repair complexity for popular Xiaomi models:
| Model | Screen type | Cost of touchscreen (₽) | Difficulty of replacement (1-10) | Frequent problems |
|---|---|---|---|---|
| Redmi Note 10 Pro | AMOLED, 120Hz | 3 500 – 5 000 | 8 | Detachment OCA-glue, non-functioning light sensor |
| POCO X3 Pro | IPS, 120 Hz. | 2 800 – 4 200 | 6 | Problems with calibration after replacement |
| Xiaomi Mi 11 | AMOLED, 120 Hz, 3D-glass | 6 000 – 9 000 | 9 | Requires reglazing of the rear window |
| Redmi 9A | IPS, 60 Hz. | 1 200 – 2 000 | 4 | Cheap Chinese analogues are often "glutched" |
Before ordering a replacement, consider:
- ⚠️ The original touchscreens are in 2-3 For Redmi budget lineup often enough quality non-original (for example, from the OEM-suppliers such as Tianma or BOE).
- ⚠️ After replacement, be sure to calibrate through the engineering menu (see section 1).
- ⚠️ On models with ultrasonic fingerprint scanner (Mi) 10T, Mi 11) after the glass is replaced, the scanner will stop working - you will need to transfer the original sensor.
If you decide to replace the screen yourself, order along with the touch screen:
- 🔧 Recruitment of mediators for parsing the phone.
- 🧴 Clay. B-7000 or LOCA plume-fix.
- 🔥 Temperature-adjusted hair dryer (for softening glue).
6. Alternative solutions: gloves, styluses and software
If repairs are delayed, and you need to use the phone now, use temporary measures:
For cold weather (the screen does not react with gloves):
- 🧤 Enable the Sensitivity to Gloves mode in Settings → Screen. → Additional (not available on all models).
- 🎨 Use a capacitive stylus (for example, Xiaomi Mi Smart Pen for Mi Pad 5 is suitable for smartphones as well).
- 🔋 Connect Bluetooth keyboard or use voice input via Google Assistant.
If the screen floats or spontaneously presses:
- 🛡️ Install the Touchscreen Repair app (helps with minor digitizer crashes).
- 🔄 Turn off Gestures. MIUI In Settings → Screen. → Navigation on the system – they may conflict with the sensor.
- 📱 Check your phone for viruses with Malwarebytes – some Trojans mimic touches for clicks on ads.
For models with an infrared port (POCO F1, Mi 8), you can use the remote control as a temporary replacement for the sensor. Connect the remote control via Settings → Connected devices → Remote control and assign buttons for basic actions.
7.Prevention: How to prolong the life of the sensor
To avoid future sensitivity problems, follow these rules:
What not to do:
- 🚫 Use alcohol wipes to clean the screen - they destroy the oleophobic coating, which is why the fingers "stick" to the glass.
- 🚫 Glue thick glasses (more than 0.3 mm thick) - they impair the conductivity of the signal.
- 🚫 Charge your phone in the cold (below) +5°C) - this leads to microcracks in the layer ITO (transparent-conductor).
What to do regularly:
- 🧼 Clean the screen with microfiber and distilled water (1 times a week).
- 🔋 Keeping the charge level under 10% (this increases the load on the screen controller).
- 📱 Update the firmware once in a while 1-2 month (in new versions) MIUI Often fix sensor bugs).
If you drop your phone frequently, consider buying a Gorilla Glass Victus model (such as the Xiaomi 13 Pro or POCO F5) that can withstand drops from up to 2 meters without losing sensitivity.
💡
Even if the screen is completely intact, the connection between the digitizer and the motherboard may be disrupted after a strong impact.
