How to reduce screen sensitivity on Xiaomi: from calibration to hidden MIUI settings

Why Xiaomi’s Touchscreen Reacts to False Touches and How to Fix It

Xiaomi's screen sensitivity is one of the most common causes of inconvenience when using a smartphone. Have you noticed that the phone spontaneously scrolls pages, opens apps or enters characters during a call? This is not always a hardware defect - in 80% of cases the problem is solved by software methods. The manufacturer puts high sensitivity sensor "by default" to ensure responsiveness even with light touch, but this often leads to false positives.

This is especially true for owners of curved screens (Xiaomi Mi 11 Ultra, Redmi K50 Pro, POCO F4 GT), where edge areas often respond to accidental palm touch. Also, sensitivity is a hindrance when using magnetic lock cases or low-quality protective glasses. In this article, we will examine all available methods, from standard MIUI settings to engineering menus and hardware checks.

Before you start setting up, make sure that the problem is not physical damage, and if the screen cracks, blows up, or moisture builds up under the film, no software method will help, and in such cases, you need to replace the touch module in the service center.

Method 1: Using the built-in sensitivity settings in MIUI

Starting with MIUI 12, the manufacturer added a separate section to adjust the sensor response, which is the safest method and recommended for use first. The instructions are relevant for most modern models: Xiaomi 13/14, Redmi Note 12, POCO X5 and later.

To change the sensitivity:

1. Open the Settings → Display.
2. Scroll down and select Sensor Sensitivity (on some firmware, the item may be called Touch Sensitivity).
3. Move the slider to the left to reduce the response, the recommended value is 50-70% of the maximum.
4. Click Save and restart the device.

If your MIUI version doesn’t have one, try an alternative way:

• 🔍 Go to Settings. → Additionally. → Special facilities → Physical capabilities → Touch control.
• 📱 There may be a sensitivity threshold (relevant to the POCO M4 Pro and Redmi 10).
• ⚙️ Some of the settings are hidden in the settings. → System system → Advanced settings.

💡

If the screen reacts poorly to touching gloves after the sensitivity change, return the slider by 80-90%. Use the sensor test in the engineering menu to fine-tune it (see Method 4).

Method 2: Disabling casual touches during calls

One of the most annoying problems is when Xiaomi's screen is triggered during a conversation, pressing buttons or activating a speakerphone, and it's because the proximity sensor is so close to the sensor.

1. Go to Settings → Applications → Calls.
2. Select Incoming Calls.
3. Activate the option to Lock the screen during a call (or turn off the sensor when talking).
4. For models with MIUI 13+, additionally enable Smart Lock – this will prevent unlocking with pocket touches.

If the problem persists, check the proximity sensor:

• 📞 In the phone application, type ##6484##.
• 🔄 Raise your hand to the top of the screen – the value should change from 5 (far) to 0 (close).
• ❌ If the sensor does not respond, cleaning or replacement is required (contact the service).

Method 3: Calibrate the sensor through a hidden menu

If standard settings don't work, try recalibrating the sensor, which resets the current response settings and sets the optimal values, and works on all Xiaomi devices, but requires caution.

Instructions:

1. Open the Phone app and enter the combination: ##36446337## (this is the sensor test code relevant for MIUI 10-14).
2. You'll see a grid of numbers on the screen, which is a visualization of the touches, and you'll touch the center of the screen and hold your finger for 5 seconds.
3. At the bottom of the screen, click Menu → Calibration (or Calibration on Russian firmware).
4. Follow the instructions on the screen by touching at the points indicated.
5. After completion, restart the smartphone.

If the code doesn’t work, try alternative combinations:

• 📱 For the Redmi Note 8/9: ##64663##
• 🔧 For POCO F1/F2: ##2664##
• ⚠️ On some firmware, calibration may be blocked - in this case, only resetting the settings will help (see Method 6).

Method 4: Engineering menu - Advanced sensitivity settings

For advanced users, fine-tuning is possible through the Engineering Mode, where you can change the sensor settings at the hardware level, but improper actions can lead to unstable screen operation.

How to get into the engineering menu:

1. Install the MTK Engineering Mode app (for MediaTek processors) or Qualcomm Engineer Mode (for Snapdragon) from Google Play.
2. Start the app and select Hardware Testing → Touch Screen.
3. In the Touch Sensitivity section, you will see the following parameters: Touch Threshold – the trigger threshold (the higher the value, the lower the sensitivity); Touch Filter – noise filter (recommended value: 3-5); Touch Debounce – delay between touches (increase to 10-15 ms to reduce rattle).

Change the settings one by one, testing the screen response after each change.

Do not change the Touch IC Version and Firmware Update settings – this may cause the sensor to be completely inoperable!

Method 5: Checking and Replacing the Protective Glass

Low-quality protective glass or film can cause false sensor alerts. Cheap coatings often have an uneven thickness or metallized layer that causes interference.

• 🧲 Remove the protective glass and test the screen without it during the day.
• 🔍 Examine the glass for microcracks or bubbles – they can distort the sensor signal.
• 📏 Check compatibility: Glasses with adhesive base thicker than 0.3 mm often cause problems.

Recommendations for the choice of protection:

• 🛡️ For Xiaomi with AMOLED-screens (Mi) 11, Redmi K40) Choose glass with oleophobic coating and thickness 0.2-0.25 mm.
• 🔄 For curved displays (Mi Mix 4, Black Shark 5) use flexible films TPU glass-plate.
• ❌ Avoid the glass "3D-glue – they often put pressure on the sensor.

⚠️ Warning: If the problem has disappeared after the glass is removed, but you want to continue using it, try gluing the glass with minimal pressure. Sometimes it helps to warm up with a hair dryer (temperature not higher than 50).°C) for uniform distribution of glue.

Method 6: Resetting settings and flashing

If all the previous methods didn't work, it could be a software failure in the sensor, in which case a reset or a firmware reinstallation will help.

1. Make a backup of the data through Settings → About Phone → Backup.
2. Go to Settings → System → Resetting settings.
3. Select Reset all settings (does not delete files, only settings).
4. After restarting, check the sensitivity of the screen.

If the soft reset didn’t help, perform a hard reset (delete all data!):

• 🔄 Hold the Loud up. + Food before the appearance of the Mi logo.
• 📱 In the recovery menu, select Wipe Data. → Wipe All Data.
• 🔧 After the reset, install the latest version. MIUI through settings → Update of the PO.

For advanced users: If the problem has occurred after the update, roll back to the previous firmware version via Fastboot or TWRP. For instructions for a specific model, look for the XDA Developers or 4PDA forum.

💡

Hard reset is a last resort. Before you do it, make sure to check the screen in safe mode (press the power button → Safe Mode). If the problem disappears, one of the installed applications is to blame.

Method 7: Hardware diagnostics and repair

If none of the software methods worked, the problem could be a physical malfunction of the sensor module or plume.

• 🔴 False touches occur in the same area of the screen.
• 💧 The screen responds to touch even when you don’t touch it.
• 🔌 The problem is aggravated when connecting charging.
• 🌡️ Sensor “floats” when heating or cooling the phone.

What to do:

1. Check the display plume, which often leaves after falls, disassemble the phone (experience required!) or contact the service.
2. Test the sensor for contact oxidation, a common problem after moisture is injected.
3. If the Xiaomi screen is still warranty, contact the official service center. Sensor defect refers to warranty cases.

Cost of repair:

⚠️ Warning: Do not use alcohol or acetone to clean your contacts, they destroy the protective coating. Use only isopropyl alcohol 99% or special cleaners for electronics.
