Xiaomi Phone: Color, Brightness and Sensor in 10 Minutes

Have you noticed that the colors on your Xiaomi screen look unnatural? Or has touch control become less responsive after the upgrade? The problem may lie in the wrong calibration settings, a procedure that many users ignore, considering it the prerogative of professionals. In fact, you can calibrate your smartphone screen yourself in a few minutes without resorting to service centers.

In this article, we will discuss three main types of calibration: color (for correct display of shades), brightness (for comfortable perception in different lighting) and touch (for accurate response of the touchscreen). Particular attention will be paid to the Redmi Note 12, POCO X5 and Xiaomi 13 models, where calibration algorithms differ from budget lines. You will also learn what hidden parameters of the engineering menu are responsible for fine-tuning the display and how to avoid typical errors in manual adjustment.

Why do you need to calibrate the screen on Xiaomi?

Xiaomi smartphone makers are setting factory calibration profiles that target the “average” user, but these settings are not always optimal:

• 🎨 Distorted colors: on budget models (e.g. Redmi) 10A) often oversatisfaction, which leads to unnatural skin tones in the photo.
• ☀️ Incorrect brightness: Automatic adjustment to lighting can work with malfunctions, especially on the lighting. AMOLED-screens (Xiaomi) 12T Pro).
• ✋ Missed touches: after update MIUI Some users have “dead zones” on the edges of the display.
• 🔋 Increased battery consumption: improper lighting settings can reduce battery life 15-20%.

Calibration solves these problems, but it is important to understand that not all parameters can be changed through a standard menu, for example, color profile correction on POCO F4 requires access to engineering settings, and to calibrate the multi-touch on the Redmi Note 11 Pro+ you will need a special application.

Calibration Types: What You Can Configure on Xiaomi

Before you start settings, determine which parameter needs to be adjusted. In the table below, the main types of calibration and their impact on the smartphone:

On most Xiaomi smartphones, color calibration is available through standard settings, but to fine-tune the sensor or sensors you will need an engineering menu (we will talk about it in the next section). AMOLED-screens (Xiaomi) 13 Ultra, POCO F5) color profile affects the battery life – too high saturation can reduce it to a high level of energy. 10-15%.

⚠️ Note: On smartphones with MIUI 14 and later factory calibration blocked for changes through ADB. Trying to get around this restriction can result in resetting all screen settings.

Method 1: Calibration of color using standard MIUI settings

This is the safest method, which does not require superuser rights or special knowledge, and is suitable for most models, including the Redmi Note 12 Pro+ and Xiaomi 13 Lite.

1. Open the Settings → Display.
2. Select Color Mode (on some firmware - Color Style).
3. Available options: 🌈 Saturated (factory profile, often oversatisfaction) 📱 Standard (close to sRGB, recommended for photo/video) 🎮 Playful (increased contrast, suitable for dynamic scenes)

Additionally.

In the models with AMOLED-screens (Xiaomi) 12S Ultra, POCO F4 GT) Adaptive Color is available, which automatically adjusts shades to lighting, but this mode may conflict with some applications (for example, Lightroom Mobile), so it is better to turn it off when working with color professionally.

If standard settings are not enough, go to the engineering menu method (described below). But remember: not all parameters there are Russian names, and incorrect values can lead to a flicker of the screen or color distortion.

⚠️ Attention: POCO X5 Pro and Redmi. K60 When you select Movie in color profiles, the brightness limit to 400 nits is automatically activated. To remove it, you need to reset the screen settings.

Method 2: Fine tuning through engineering menu (MTK/Qualcomm)

The engineering menu is a hidden settings section that allows you to change the screen settings at the firmware level. Careful: incorrect actions here can lead to unstable display operation.

For smartphones on Qualcomm Snapdragon (POCO, Xiaomi flagships)

Enter the combination in the phone application:

##36446337##

The MMITest menu will open. Go to the section:

Display → Screen Color Calibration

Here you will see the parameters:

• 🔘 Red/Green/Blue Gain - enhancement of primary colors (values from 0 before 255)
• 🔘 Color Temperature – temperature in Kelvin (recommended: 6500K)
• 🔘 Gamma Correction (value 2.2) is the standard for sRGB)

For smartphones on MediaTek (Redmi budget series)

Enter the combination:

##4636##

Select Testing → Display. Here you can find:

• 🔘 White Balance – White Balance (adjustment) RGB-channel)
• 🔘 Backlight – manual backlight setting (caution: values above 255 can damage the matrix!)

After the changes, be sure to restart the device. If the screen starts to flicker or the colors are distorted, reset through the same partition (Restore Default).

Method 3: Sensor calibration (multi-touch and responsiveness)

If your Xiaomi doesn't respond well to touch or miss gestures, the problem may be the shaky touchscreen calibration.

1. Install the Touchscreen Calibration app from Google Play.
2. Run a responsiveness test – the program will show areas with delayed response.
3. If problems are detected, calibrate via Settings → Additional → Touchscreen → Calibration (not available on all models).
4. To manually adjust, connect via ADB and follow: adb shell wm touch calibration yes Then follow the on-screen instructions (touch targets at the corners of the display).

On the POCO F3 and Redmi K50, after calibrating the sensor, you may need to reinstall navigation gestures. To do this, go to Settings → Display → Movements → Guest settings.

💡

If the sensor becomes less sensitive after calibration, try turning off the Gloves mode in the screen settings, which artificially increases sensitivity, which can conflict with the new calibration.

Calibration of the light sensor (auto-brightness)

The malfunction of the light sensor is a common problem on Xiaomi, especially after upgrades.If the screen is too dim in bright light or blinding in the dark, follow these steps:

1. Open the settings → Display → Automatic brightness.
2. Turn off the option, set the brightness manually to 50%.
3. Turn on Adaptive Brightness mode and wait until the smartphone “learns” your preferences (it will take 1-2 days).
4. If the problem persists, reset the sensor settings via the engineering menu: ##0588### Select Light Sensor Calibration → Do Calibration.

On the Xiaomi 13 Pro and POCO X5 Pro 5G, the light sensor is calibrated automatically when the autobrightness is first turned on. If the reset did not help, check the physical cleanness of the sensor (it is located next to the front camera) - dust or protective glass can distort the readings.

💡

After calibrating the light sensor, avoid using colored films on the front panel – they filter the light, which leads to incorrect readings.

Frequent Mistakes and How to Avoid Them

Even experienced users make mistakes when calibrating the screen, and here are the most common ones and ways to prevent them:

• ❌ Too high color temperature (above) 7500K) — It causes eye fatigue. Optimal range: 6000-6500K.
• ❌ Using a “gaming” profile for everyday tasks – increased contrast distorts the colors in photos and videos.
• ❌ Sensor calibration on a dirty screen – dust particles or greasy spots lead to inaccurate results.
• ❌ Changing Backlight settings in the engineering menu – values above 255 can damage the backlight AMOLED-matrix.

Another common problem is that color profiles are not compatible with apps, such as Netflix or YouTube, which can automatically turn on. HDR-a mode that ignores your settings. To avoid this, turn off the Automatic Color Improvement option in your application settings.

⚠️ Note: Xiaomi with Snapdragon 8 Gen 2 processor (Xiaomi 13 Ultra, POCO F5 Pro) manual color calibration through an engineering menu can result in artifacts when viewed HDR-In this case, return the factory settings.
