Many Xiaomi smartphone owners face a situation where the device stops responding to light touches or, conversely, executes commands when touching accidentally. Often this is due to a glued protective glass or individual features of the digital converter. MIUI and HyperOS operating system provide a hidden feature that allows you to adjust the response of the display without installing third-party programs.
In this article, we will discuss in detail how to change the sensitivity of the screen of the Xiaomi phone to restore comfort when typing and navigating the interface, you will learn where the engineering menu hides, how to use the developer mode and what nuances should be considered when calibrating the touchscreen.
Before making any changes, it is important to understand that sensor malfunctions can be caused not only by software failures but also by physical damage, and if the problem persists after setting up, a deeper diagnosis or replacement of the display module at the service center may be necessary.
Standard configuration through the developer mode
The safest and most affordable way to change response settings is to use the built-in developer mode, which requires no super-user rights and is safe to guarantee the device, but by default, this section is hidden from the eyes of the average user to prevent the accidental change of critical system parameters.
To activate hidden functions, you need to click on the build number several times in the About menu, after which a new item will appear in the settings, where the desired switch is located, the process is simple, but requires careful execution of the sequence of actions.
- 📱 Open the Settings menu → About the phone and find the line "Version" MIUI» or "Version" OS».
- 🔨 Quickly click on this line. 7-10 Once in a row, until a notice appears "You became a developer».
- ⚙️ Return to the main settings menu, go to Advanced Settings → For developers.
- 🖱️ Find the item “Increase touch sensitivity” and activate it.
⚠️ Note: After activating the developer mode, do not change other parameters unknown to you, as this can lead to unstable operation of the Android operating system.
Activating this mode instantly changes the way you process incoming touchscreen signals, so if you had to push hard on the screen, now light touches will be recognized instantly, and this is especially true for owners of high-density or thick protective glasses.
☑️ Pre-calibration check
Using the CIT Engineering Menu for Diagnostics
A deeper tool is the CIT (Customer Integration Test) Menu, a service section designed by Xiaomi engineers to test the hardware of the device before selling, where you can not only check the performance of the sensor, but also start the calibration procedure.
To enter the menu, a special code is used, which is typed in a standard "bell ringer", and after entering the combination, a list of all the tests available will open, and we are interested in the section related to TouchPanel or touch screen.
| Parameter | Description of function | Recommended value |
|---|---|---|
| Single Touch | Testing of single-touch response | It's okay. |
| Multi Touch | Multi-touch test (up to 10 points) | It's okay. |
| Pressure | Pressure on the screen | Average. |
| Calibration | Resetting and reconfiguring the sensor | If necessary, |
Inside the sensor test, the option "Recalibrate" or "Calibration" is often available. When you click on it, the system will ask you to consistently press multiple dots on the screen to align the grid, which helps if the cursor or finger "goes away" from the actual touch.
Secret codes for different models
Solving the problems with protective glass
One of the most common reasons for the decreased responsiveness of the screen is the glued protective glass. Even high-quality tempered glass creates an additional layer that can shield the electrical signal of the finger, in such cases, standard sensitivity may not be enough.
Modern versions of MIUI and HyperOS have a separate option specifically designed to work with protective coatings, which programmatically amplifies the signal coming from the touchscreen, compensating for losses.
- 🛡️ Go to Settings. → Screen (or “Additional»).
- 🔍 Find the switch “Gloves mode” or “Increased sensitivity».
- 👆 Activate the feature if you use thick protective glass or often work with gloves.
It's worth noting that turning on this mode can lead to so-called "phantom taps," where the phone responds to a fly or raindrop. If you remove the protective glass, be sure to turn off this feature back.
💡
If after sticking the glass, the screen stopped responding to the edges, try changing the interface or font in the screen settings to shift the important buttons from the edges of the display.
Calibration through third-party applications
If the built-in system fails to solve the problem, specialized applications from Google Play come to the rescue, which allow you to perform a finer setup or forcibly recalibrate sensor using algorithms other than the standard ones.
A popular tool is the Touchscreen Calibration app or similar high-rated utilities, and the principle of their work is to force the restart of the touchscreen driver with new parameters that you specify during the test.
The process is usually this: the app says click on the cross in the center of the screen, then in the corners, and based on the speed and accuracy of your clicks, it forms a new sensitivity profile, which is especially useful if you have a cursor walking.
⚠️ Note: Only download calibration apps from trusted developers with a lot of feedback to avoid installing malware that collects data about your touches.
Remember that third-party applications cannot change the physical sensitivity of the matrix, they only adjust the software threshold of the response. If the matrix is physically damaged (cracks, flooding), the software is powerless.
Diagnostics of hardware faults
Sometimes the problem is not the settings, but the hardware. The digital converter (digitizer) can fail over time, especially after falls or moisture, and it is important to be able to distinguish between software glitch and physical failure.
If the "dead zones" (the places where the screen does not respond) have clear geometric boundaries or only appear when the case is heated, this is a sure sign of hardware malfunction.
- 🔋 Check the battery charge: at low charge (less) 10-15%) Some Xiaomi models artificially reduce the sensitivity of the screen to save energy.
- 🌡️ Overheating: If the phone is hot, the touchscreen may not work properly.Let the device cool down.
- 🔌 Charging: Cheap power supplies can cause interference that makes the screen “frazzle” while charging.
For accurate diagnosis can be used ADB-If you have access to a computer, you can connect the phone to the computer. USB and enabling debugging, you can output the log of the touchscreen events in real time.
adb shell getevent -l | grep -i touchThis command will show the event stream from the sensor, and if you touch the screen, the strings in the log don't appear or are delayed, the problem is at the driver or plume level.
💡
If the screen only reacts after a strong reboot or only works normally in safe mode, it is likely that one of the apps you have installed is causing a conflict.
Prevention and care of touchscreen
To keep Xiaomi’s screen sensitivity stable for years to come, it’s important to properly care for the display surface.The buildup of fat, dirt and static electricity can significantly distort the sensor.
Regular cleaning of the screen with microfiber and special means (or just a slightly wet wipe) helps to maintain good contact of the finger with the surface, and avoid using the phone in conditions of high humidity or dust.
Remember to update the software periodically. MIUI updates often come with patches that improve the performance of display drivers and fix bugs with multi-touch.
