Owners of the popular smartphone Xiaomi Redmi Note 8 Pro often face a situation where the display reacts to touch too aggressively or, conversely, ignores light pressing. IPS-The matrice, has in the arsenal MIUI Sensitivity settings, which by default may not be ideal for every user, especially when using protective glass or in conditions of high hand humidity.
A touchscreen malfunction can make it torture to use a gadget, causing random application launches or typing errors. Screen calibration is a process that allows the sensor layer to respond to the wearer's individual habits. In this article, we'll look at all the methods available, from simple interface settings to the use of hidden engineering codes.
Before embarking on radical measures such as resetting or flashing, it is worth trying software adjustment methods.The Redmi Note 8 Pro has a powerful processor and optimized shell, which allows you to flexibly manage input parameters. Proper tuning will not only improve comfort, but can also extend the life of the display, reducing the number of unnecessary activation cycles.
Standard Sensitivity Settings in MIUI
The first step to solving the problem should always be to check the basic parameters of the system. The MIUI shell gives the user access to control response speed and sensitivity in the usual settings menu, it is the most secure method that does not require special knowledge and does not pose risks to the stability of the operating system.
You go to Settings, then select Settings, and that's where the menu that controls the physical settings of the device is hidden, and then you find the option of Pointer Speed, and by default, the slider is often set in the middle or shifted to the right, which increases sensitivity.
💡
Try setting the pointer speed slider to the far left position for minimal sensitivity, then gradually shift it to the right until you find a comfortable balance.
If a standard slider isn't enough, you should pay attention to the glove mode. In some versions of the firmware, it can be activated by default or automatically, making the screen hypersensitive. Turn off the glove mode function if it is active to reduce the response to light touches.
- 📱 Go to Settings. → Additional settings.
- ⚙️ Find the section Speed of the pointer and adjust the slider.
- 🧤 Check availability and status of the option Mode of work in gloves.
- 💡 Restart the device to apply changes.
Use of the Engineering Menu for Calibration
Deeper tuning is available through the Android engineering menu.This hidden interface is designed to test hardware and allow for accurate touchscreen calibration. For the Redmi Note 8 Pro, this is often the only way to fix software glitches in the sensor.
To get into the testing menu, open the standard Phone app and dial ##6484##. The device will automatically go to CIT (Customer Integration Test) mode. Here is a long list of tests of various components. You need to find the item associated with TouchPanel or TP.
☑️ Checking in the engineering menu
Inside the test, you're usually asked to swipe lines or click on certain points, which allows the system to re-determine the boundaries of the workspace and sensor sensitivity, and if the problem persists after the test, you can try recalibrating if that option is available on a specific menu.
⚠️ Warning: Do not change the settings in other sections of the engineering menu unless you are sure of their purpose.This can lead to improper operation of the modem, sensors or other critical systems of the smartphone.
Effects of protective glass and films
One of the most common reasons for changing screen sensitivity is the use of accessories: thick protective glass or low-quality film can shield the signal, causing users to increase sensitivity, or, conversely, create a “bridge” effect, causing false positives.
If you've recently installed a new protection and noticed changes in the touchscreen, try temporarily removing it. The quality of the oleophobic coating and the thickness of the glass directly affect the electrical capacity of the screen. Cheap counterparts often don't have the necessary layers, which disrupts the capacitive touch.
How to distinguish high-quality glass?
In some cases, re-sticking the security element with careful dust removal helps, and it is also worth checking whether the accessory closes the edge of the display, where hidden controls or proximity sensors may be located, which indirectly affects the interface response.
Comparison of screen setting methods
There are several approaches to solving the sensitivity problem, and each has its own advantages and disadvantages, and the choice of method depends on whether the problem is hardware or software, as well as the level of user training.
Below is a table that will help you choose the best solution path for your Redmi Note 8 Pro. We will compare the efficiency, complexity and risks of different methods.
| Method | Efficiency | Difficulty | Risks. |
|---|---|---|---|
| Setting up the slider in MIUI | Medium | Low. | Absent. |
| Engineering Menu (CIT) | Tall. | Medium | Low. |
| Removal of the protective glass | High (if the cause is in it) | Low. | Screen damage during removal |
| Third-party annexes | Low. | Medium | Advertising, data collection |
As you can see from the table, the safest and most effective method is to use the built-in system tools, and you should resort to third-party software only in extreme cases when the regular MIUI tools do not work.
Diagnostics of hardware problems
If software methods don't help, the problem may be the hardware.The Redmi Note 8 Pro is a reliable device, but physical impacts, falls or moisture could damage the display plume or touchscreen itself.
Note the nature of the "glitch." If the screen "lives its life" (phantom presses in certain areas) even after resetting and calibrating, this is a sure sign of hardware failure. It is also worth checking whether the battery is swelling, as a bloated battery can press on the matrix from the inside, causing false positives.
For a final diagnosis, you can run a full test of the equipment through the same engineering menu by selecting the Complete Function Test. The system will check all the nodes and report errors. If the touch screen test is not passed, you will most likely need to replace the display module.
⚠️ Warning: If you notice a bloating battery (the screen is arching or moving away from the frame), immediately stop charging and using the device.This is dangerous and requires an urgent replacement of the battery in the service center.
Third-party calibration applications
There are many apps in the Google Play store that promise to fix the touchscreen, which are based on the principle of forced reboot of the sensor driver or creating a map of dead zones, but their effectiveness on modern versions of Android is often limited by access rights.
One popular tool is the Touchscreen Calibration, which takes the user through a series of tests and then tries to recalibrate the system. Be sure to read reviews before installing, as some programs may contain aggressive advertising or malicious code.
The use of these utilities is a last resort, and they often simply emulate the settings available on the engineering menu, but they do so through an uncomfortable interface. If Xiaomi's built-in tools have not worked, it is unlikely that a third-party app will solve the problem dramatically.
💡
Third-party applications do not have deep access to screen drivers, so their effectiveness is limited by software failures, but not hardware defects.
