Modern Xiaomi smartphones are equipped with advanced AMOLED and LCD arrays that are factory calibrated by default. However, even flagship models such as the Xiaomi 13 Ultra or Redmi Note 12 Pro can show poor color perception in certain lighting conditions. Users often face a situation where the white color on the screen goes yellow and the skin shades in photos look unnatural. This is not always a panel marriage, but requires intervention in software settings to achieve a reference image.
Calibration is not just for perfectionists, but also for those who spend a lot of time reading or editing photos. Wrong color temperature can cause eye fatigue, and incorrect gamma correction distorts content. In this article, we will examine all available methods, from standard MIUI interface settings to hidden engineering menus available to power users. You will learn to adjust white balance and eliminate color artifacts without using third-party equipment.
It is important to understand that Xiaomi display calibration is only possible by software methods through the engineering menu or standard settings, since hardware calibration with a colorimeter at home is not possible. We will consider safe ways to change the parameters that will not lead to loss of warranty or damage to the system. Before starting any manipulations, make sure that the battery level is sufficient so that the device does not turn off at a critical time of setting.
Diagnostics of color rendering problems
Before making changes to the system, you need to accurately determine the nature of the distortion. Often users confuse the software "blue light filter" (reading mode) with a hardware defect or improper calibration. If your screen is yellow only in the evening or in certain applications, most likely, Night Light or adaptive adjustment is activated. Check this in the settings section "Screen" by temporarily turning off all automatic modes.
There are a few common problems to look out for before starting the procedure: Uneven backlighting, known as the “lightlight effect”, is more common on LCD screens of Redmi budget models, whereas AMOLED panels can suffer from a shift in color balance towards green or pink at low brightness.
⚠️ Note: Do not confuse software calibration with trying to repair physical damage to the matrix. If there are vertical stripes, flickering or black spots on the screen, the software settings will not help - you need to replace the display module.
For initial diagnosis, use a special test image. Upload a pure white, black and gray photo in full resolution and open them to the full screen. This will help identify lights, uneven backlights or obvious color skews. If you see a clear yellowness or blue on a white background that can not be removed by a brightness slider, then you need to deep customize color profiles.
Basic Color Profile setting
The first and safest step is to work with standard MIUI or HyperOS shell settings. Manufacturers often set the default saturated colors to attract attention in the store, but it’s not always convenient to work with. Go to Settings → Screen → Colors and contrast. Here you’ll find the color switch, which is the main tool for rapid calibration.
The system offers multiple presets, each of which changes color gamut and saturation. The standard mode usually corresponds to the sRGB space, which is ideal for browsing the web and social networks. The saturated color mode extends the reach to the sRGB space. DCI-P3, useful for viewing HDR-It can distort colors in regular applications, but Standard Colors mode tries to mimic natural color reproduction, which is close to reality.
To fine-tune your settings, use the extended menu if available in your model. By clicking on a gear or selecting "More," you can access saturation and hue sliders. This allows you to manually adjust the balance if standard profiles seem too cold or warm. Don't be afraid to experiment, as all changes can be reset to factory values with a single tap.
- 🎨 sRGB, the Internet standard, provides the most accurate color transfer for most content.
- 🌈 DCI-P3 — wide color coverage used in cinematography and professional video shooting.
- 👁️ Adaptive mode – automatically changes the parameters depending on the content displayed.
- 🌙 Reading mode – reduces eye strain by imitating electronic paper, but greatly distorts colors.
Engineering menu for accurate calibration
If standard settings are not enough, the CIT (Customer Integration Test) is a hidden part of the system designed to test hardware components in the factory, accessed through a set of special code in the Phone application. Enter the combination ##6484## or ##4636##. If the code does not work, your version of the firmware may restrict access and require activation via ADB.
In the engineering menu, you're interested in the display-related section, which can be called Display, LCD or Screen. Inside, you'll find color tests and, in some cases, the ability to reset calibration data or change the base parameters of the gamut. Be careful: changing unknown parameters in this menu can lead to incorrect touchscreen or color inversion.
☑️ Check before entering the engineering menu
One of the useful features in the engineering menu is a test for the uniformity of the backlight and broken pixels. By starting a cyclic change of colors (red, green, blue, white), you can carefully examine the matrix at maximum and minimum brightness levels. This will help to identify defects that are not visible during normal use. If you find serious deviations that are not fixed software, this can be the basis for contacting the service under warranty.
What if the code doesn't work?
Importantly, newer versions of HyperOS often block access to deep calibration through the engineering menu, so the only alternative is to use third-party apps or wait for firmware updates to return functionality. Don't try to hack the system to gain root rights just for the sake of calibration, this can disrupt banking applications.
Use of calibration applications
When built-in tools are scarce, specialized applications from Google Play come to the rescue, with the leader in this area being the Screen Balance app (requires root rights) or the Color Calibrator, which allows you to change the values of color channels (Red, Green, Blue) at the level of the display driver, which gives a much more accurate result than standard filters.
These applications often require developer mode activation and ADB permission. Once installed, you can manually adjust the intensity of each color. For example, if the screen goes green, you can reduce the value of the green channel. This is especially true for models with cheap TFT or IPS matrices, where factory calibration often suffers.
⚠️ Attention: Apps that change the color of the screen without root rights work as an overhead filter, which can increase battery consumption and reduce maximum brightness, as the system will compensate for the dimming.
There are also applications for creating calibration profiles based on reference images, where you download a special table, compare it to a reference on another, more accurate screen, and make adjustments, which takes time and discretion, but allows you to achieve acceptable results even on budget Poco or Redmi devices.
| Annex | I need a Root. | Impact on the battery | precision |
|---|---|---|---|
| Screen Balance | Yes. | Low. | Tall. |
| Color Calibrator | Yes. | Low. | Tall. |
| Night Screen | No. | Average. | Medium |
| Blue Light Filter | No. | High. | Low. |
Resetting display settings to factory
Sometimes calibration is not required to improve, but to return to the original state after unsuccessful experiments. If colors become unnatural or artifacts appear, reset. In the Settings menu → Screen, find the Reset or Default button. This will return the color temperature and gamut to the factory values set by Xiaomi engineers.
If the software reset doesn't work, you can try a more radical method, which is to clean the cache of the system through the recavers. To do this, turn off the phone and press the button combination (usually Volume+ and Power). From the recavator menu, select Wipe Cache. This will not delete your personal data, but will clear temporary files that may conflict with the display settings.
💡
Before resetting, take a picture of the current screen settings on another phone, which will help you manually restore your usual values if the automatic reset makes the picture too faded.
In extreme cases, when the problem is caused by a firmware failure, a full Hard Reset helps. Remember that this action will delete all data from the device, so be sure to back up to Xiaomi Cloud or your computer. After the reset, the system will reinitiate the display drivers, which often solves the problems with “floating” colors.
Specificity of AMOLED and LCD matrices
Understanding the type of matrix you have is critical to calibrating correctly. The AMOLED screens used in Xiaomi flagships have self-luminous pixels. They don't require backlighting, which gives you the perfect black color, but they're sensitive to burnout. When calibrating these screens, you don't recommend using static images at maximum brightness.
LCDs (IPS/TFT) arrays, in the budget segment, use constant backlighting. Their main problem is the “lightlight effect” (uneven illumination at the edges) and a less deep black color. Calibration of LCDs often boils down to selecting a level of brightness and color temperature to minimize the visibility of the lights and make white less “dirty”.
- 🔴 AMOLED: Perfect contrast, burnout risk, calibration of each pixel.
- 💡 LCD: Uniform brightness, risk of lighting, calibration is limited by backlight setting.
- ⚡ Refresh Rate: On AMOLED frequency-change (60/120 Hz can visually change brightness due to technology LTPO.
- 🛡️ Eye protection: On LCD It is used by the squirrel (swimmering), AMOLED — DC Dimming (constant current).
AMOLED owners should pay attention to the DC Dimming feature (often hidden in the engineering menu or activated via ADB).It reduces the flickering of the screen at low brightness, which makes the picture more stable and pleasing to the eye, although it can slightly distort the colors in the shadows. For LCD screens, it is more important to adjust automatic brightness, since their brightness range is often narrower, and manual adjustment is required more often.
💡
The type of matrix dictates the calibration method: for AMOLED, white balance and protection from burnout are more important, and for LCD, the fight against uneven backlighting and PWM is more important.
