Professional screen calibration Xiaomi Redmi 5 Plus

Owners of Xiaomi Redmi 5 Plus often face a situation where the display ceases to respond to touch with the same accuracy, this can manifest itself in the form of “phantom” presses, shifting the cursor or completely ignoring commands in certain areas of the matrix.

The sensor adjustment procedure allows the system to re-determine the workspace boundaries and touch sensitivity. 5 Plus is equipped with IPS-resolution-matrix 1080×2160, A software failure can significantly distort the perception of color reproduction or response. 40%, to avoid sudden shutdown of the device.

There are several ways to perform this operation, from built-in system functions to the use of the MIUI engineering menu. In this article, we will discuss the most secure and effective methods that will help restore the correct operation of your gadget.

Preparing the device for sensor settings

Before you start calibrating directly, you need to prepare the Android operating system for changes. Any background processes can interfere with the sensor, creating false readings. Clearing the cache and closing the unnecessary applications is the first step to a successful procedure.

Remove the protective film or glass if they have severe damage or contamination at the edges, as this can distort the electric field of the touchscreen. It is also worth checking whether the "In pocket" mode or other functions that block part of the screen are turned on.

Be sure to reboot the device before any manipulations begin, this action will clear the RAM from temporary driver errors. After turning on the phone, give the system 2-3 minutes to fully load all services before proceeding to the next steps.

• 🧹 Close all running apps through the multitasking menu.
• 🔋 Make sure the battery level is above 50%.
• 🧼 Wipe the screen with a soft microfiber cloth without pile.
• 📱 Remove the cover if it covers the edges of the display.

💡

Use only the original charger during setup, as cheap power supplies can interfere with the capacitive layer of the screen.

Use of the built-in CIT engineering menu

The most reliable way to diagnose and adjust is to use the hidden CIT (Customer Integration Test) menu, a tool specifically designed by the manufacturer to test hardware components of the device, which requires no root rights and is safe for standard MIUI firmware.

To enter the menu, you need to open the standard Phone app and dial a special character combination. Enter the code ##6484## on the dial keyboard. The system automatically recognizes the command and redirects you to the test menu, bypassing the call screen.

In the list that opens, you need to find a item related to the display testing, which can be called Touchpanel, Display, or Version. Select the appropriate item to go to the GUI, and here you can see how the system reads the coordinates of your touches.

In the test mode, you'll see a grid or field that you need to paint over with your finger, and you'll notice that if you don't draw or interrupt lines in certain areas, it indicates an area that needs special attention or indicates physical damage, and you'll have to complete the test to get the system to record the results.

Calibration through hidden Android settings

If the engineering menu didn't work, or if the CIT interface seems too complicated, you can use the standard Android calibration tool, which is less informative, but often effective at resetting sensitivity, and it works at the system input driver level.

To activate this mode, go back to the dial menu and enter the code ##2664##. A white field will appear on the screen that says "Touch Screen Calibration." Click the center of the screen to start the process. You will be prompted to consistently click on several dots appearing in different parts of the display.

Accuracy in this mode is critical. Try to get exactly into the center of the emerging targets. The system remembers the deviations and makes adjustments to the input processing algorithms. After all the points have been passed, the settings are saved automatically.

⚠️ Warning: Do not interrupt the calibration process if the points stop appearing. Wait for a message of successful completion or return to the menu. Premature exit may lead to incorrect data retention.

Once the procedure is complete, be sure to reboot your smartphone completely, and only after the system is turned on, the new settings will take effect. If the problem persisted due to a software driver failure, it should disappear.

Color rendering and brightness setting

Calibration is not only about touch sensitivity, but also about visual perception. Xiaomi Redmi 5 Plus allows you to adjust color temperature and saturation through standard settings, which helps compensate for age-related "gone" of the matrix colors or individual preferences of the user.

Go to Settings → Screen, where you can find basic parameters like brightness, avolightness and bedtime. To fine-tune it, select Color Mode or Color Mode. The system will offer several: Standard, saturated, contrast.

For professional adjustment, use a color temperature slider. Shifting to cooler shades makes the image sharper and whiter, and warm tones give the picture a yellowish, papery hue. White balance affects eye fatigue during prolonged reading.

Experiment with settings in different lights. What seems like a perfect day may be too bright at night. The perfect color calibration is a subjective sense of comfort for your eyes, not a strictly defined technical setting.

Resolving multi-touch problems

Multi-touch, the ability of the screen to recognize multiple simultaneous touches, is critical for gaming and easy image zooming. Redmi 5 Plus claims support for up to 10 simultaneous touches. If the device stops responding correctly to zoom gestures, this feature needs to be checked.

You can check multi-touch through your browser. Open a multi-touch.me site or similar service. Tap the screen with several fingers at the same time. The site will show you the number of recognized dots. If fewer dots are displayed than you attached, there may be a driver or plume problem.

Often, the multi-touch problem is static electricity or a poor charger, so try to disconnect your phone from the network and check the sensor, and you should also reset to factory settings if the software methods don't work, but this is a last resort.

In some cases, disabling the zoom function in the special features section helps. This feature, designed for the visually impaired, can conflict with game gestures. Check the settings in the Settings section → Advanced settings → Special features.

Resetting and final check

If none of the calibration methods worked, it remains to perform a full reset (Hard Reset) that will return the phone to the “out of the box” state, removing all user data and potentially conflicting applications.

To perform the reset, go to Settings → About Phone → Reset. Select “Clear All Data.” The process will take a few minutes, after which the device will restart. In a clean system without third-party software, it is easier to determine whether the problem was software.

After the initial setup, recheck the sensor, and if there are touch gaps or dead zones in the clean system immediately after the reset, there is a high probability of physical malfunction, it can be a effluent plume, a plume damage, or a touchscreen controller failure.

⚠️ Warning: If the problem persists after the reset, further software manipulation is pointless.

Remember that the Xiaomi Redmi 5 Plus is a time-tested device and most problems are solved software, but physical impact (falls, moisture) can lead to irreversible changes in the structure of the display module.

💡

If calibration and resetting did not help, the problem lies in the physical damage to the touchscreen or plume, and replacement of components is required.
