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

Why does Xiaomi Redmi’s screen react poorly to touch?

Touch screen sensitivity is one of the key characteristics affecting smartphone comfort. Xiaomi Redmi owners (especially Note models) 10/11/12, Redmi 9/10 or POCO X3/X4) Often faced with problems: the screen does not respond to light touch, requires a strong press or "sticks" when scrolling. MIUI, incorrect settings), and hardware (display damage, sensor wear).

In 80% of cases, the problem can be solved without going to the service center – just use the built-in tools Android and MIUI. However, it is important to distinguish low sensitivity (the screen reacts, but with a delay) from complete inoperability of the sensor (touch is not recognized at all).

In this article, we’ll look at 7 proven ways to increase screen responsiveness, including hidden Xiaomi settings, calibration through engineering menus, and hardware checks. Start with the simplest methods, which help 60% of the time.

1. Check the basic sensor settings in MIUI

The first thing to do is to make sure that the system does not turn off the key functions responsible for touch processing, and there are several parameters in MIUI that can indirectly affect sensitivity:

• 🔍 Left-handed mode: if activated, it can change the response zones of the screen. → Additionally. → Special facilities → Left-handed mode.
• 🖐️ Gestures: Conflict between navigational gestures and touches sometimes causes delays.Switch off gestures in Settings → Display. → Navigation panel and check the screen response.
• 🛡️ Protective film or glass: thick or poor coating can block the signal. Try removing it and testing the sensor.

It’s also worth checking the power saving mode. In Xiaomi, it can limit processor performance, which affects the speed of touch processing. Go to Settings → Battery → Power saving mode and turn it off.

💡

If the screen does not respond well in a particular application (e.g., in games), try disabling battery optimization for that software in Settings → Apps → Permissions → Auto Run.

2. Calibration of the sensor through the engineering menu

The hidden engineering menu (#36446337##) allows you to manually calibrate the touchscreen, a technique that works on most Redmi models, but requires caution that the wrong settings can make things worse.

Step-by-step:

1. Open the Phone app and enter the combination ##36446337## (for some models, ##6484##).
2. Select Touch Screen Test or Sensor Calibration.
3. Follow the instructions on the screen: you usually need to touch the crosses in different areas of the display.
4. After calibration, restart the smartphone.

Important: if after calibration the screen began to react worse, return the settings to factory through Settings → About Phone → Reset settings (select “Reset only settings”, without deleting data).

Setting Sensitivity through ADB (for Advanced)

If standard methods fail, you can change the sensor settings via ADB (Android Debug Bridge), which is suitable for users familiar with the command line. Redmi based on MIUI 12/13/14 supports such commands:

adb shell settings put system touch.pressure.scale 1.2


adb shell settings put system touch.size.scale 1.1

Here:

• touch.pressure.scale – Pressing force (value from 0.8 to 1.5).
• touch.size.scale is the touch recognition zone (value 0.9 to 1.3).

After you apply the commands, restart the device. If the screen reaction becomes worse, return the values to 1.0 (default).

4. Update firmware and reset settings

Often the sensitivity issue arises from outdated firmware or conflicts after an update. MIUI:

1. Go to Settings → About the phone → System update.
2. If you have a new version, install it (preferably via Wi-Fi).
3. After the update, perform a soft reset: Settings → About Phone → Resetting → Reset all settings (application data will be saved).

If the problem has occurred after the update, try to roll back to the previous version of MIUI via Fastboot (the instructions are available on the Xiaomi Community forum).However, note that rollbacks can lead to a lockdown of the bootloader on new models.

💡

Before resetting, save data via Settings → About Phone → Backup or Mi Cloud. Recovery will take less time than manually configuring the device.

5. Checking hardware problems

If the software methods did not help, the cause may lie in physical damage:

For self-diagnosis:

1. Call the phone – if the screen is not responding, but the call is coming, the problem is in the sensor.
2. Connect the device to the PC – if the computer recognizes Redmi, but the screen is dead, the display module is to blame.
3. Check the response to touch in Safe Mode (press the power button → “Reboot Safe Mode”). If the screen is working properly, it is the software’s fault.

💡

If the phone falls or gets wet, don't try to disassemble it yourself - the risk of damage to the plumes is too high.

6. Alternative solutions: protective glasses and applications

Sometimes the problem lies not in the screen itself, but in external factors:

• 📱 Protective glass: cheap, low-transparency glass blocks the infrared beams of the sensor, try removing it or replacing it with the original one (e.g. Xiaomi Tempered Glass).
• 🧤 Gloves or wet hands: Redmi sensors do not recognize touch through dielectric materials. Use special gloves with conductive threads.
• 🔧 Calibration applications: Utilities like Touchscreen Calibration or Screen Touch Test help test reaction zones, but they don't replace system calibration!

If you use a magnet case (for example, for wireless charging), it can affect the sensor. Try to remove the case and check the reaction of the screen.

7. When to contact the service center?

If none of the methods worked and the screen is still not responding well, it's probably a hardware problem.

⚠️ Note: after self-disassembly Xiaomi Redmi (especially models with a high-end AMOLED-If the phone is warranty-free, don't open it, contact an authorized service center.

• 🔧 The screen only responds to very strong pressing (symptom of sensor wear).
• 💥 On the display, you can see divorces or stripes when you turn on.
• 🔄 The problem appeared after a fall, impact or moisture hit.

The cost of replacing the display module in Xiaomi Redmi ranges from 3,000 to 8,000 rubles (depending on the model). On the POCO X3 Pro or Redmi Note 11 Pro + with AMOLED, the price is higher than on the Redmi 9A with IPS.
