Many Xiaomi, Redmi and POCO smartphone owners are faced with a situation where the device’s screen suddenly changes color temperature, turning yellow or warm.This is due to the activation of the vision protection feature, which often turns on automatically on a schedule or when a dark theme is turned on. For some users, this becomes a problem, especially if they are used to cold shades or work with graphics that require accurate color reproduction.
There are several ways to disable this mode, because the MIUI shell and the new HyperOS can be spread across different menus. Sometimes users confuse the night mode with the read mode or automatic brightness. It is important to understand the difference between these features so as not to turn off the excess. In this article, we will discuss all possible options for eliminating the yellowness of the screen.
We'll look at the standard paths through the settings menu, the use of the engineering menu for advanced users, and the nuances of working with a dark theme. You'll learn how to set up a schedule so that the screen doesn't change color at the wrong time, or how to completely remove software-based light filtering. Get ready to dive into the system settings of your gadget.
Main reason: Vision protection regime
The main culprit behind the change in color is Reading Mode, which is designed to reduce eye strain in the evening by reducing blue light. However, the algorithms used by Xiaomi smartphones sometimes work too aggressively to make the image look unnatural even during the day, often without users even noticing when it was activated.
To check and disable this feature, you need to go to the appropriate menu. The path may vary slightly depending on the version of the operating system, but the logic remains the same. If you want to get the most natural colors, this item must be turned off completely or configured manually.
Follow the above algorithm of actions to access the settings:
- 📱 Open the Settings app on the main screen.
- 👁️ Find and select the Screen (or Screen and Brightness) section).
- 🛡️ Click on Vision Protection (older versions may call Reading Mode).
- ❌ Turn the switch to the off position.
⚠️ Note: In some versions of the shell MIUI The item may be called "Eye Safety." If you don't find a match, look for an icon that looks like an eye or a book.
When the screen is turned off, it should be instantly cooler, and if the colors are the same, it may be that the problem is elsewhere or that a third-party filter is activated, and it's also worth checking if the Brightness Limiting feature, which sometimes works in conjunction with vision protection, is enabled.
💡
Vision protection mode is a blue light software filter that turns the screen yellow, and completely shutting it down returns the color reproduction of the matrix to the factory.
Setting up the schedule and filter parameters
Not all users want to give up eye protection completely, because it really helps you sleep at night. Instead of completely turning off, you can flexibly adjust the filter settings, you can choose when to turn on the mode and how much it should distort colors, which gives you a balance between comfort and correct color reproduction.
There are additional options available inside the Vision Protection menu. You can choose Classic or Paper mode. The second option makes the screen monochrome, which often confuses users who think the phone is broken. Make sure you choose the standard mode if you plan to just adjust the intensity.
For fine tuning, perform the following actions:
- 🕒 Select the Schedule option and set a time interval when you really need the mode.
- 🌡️ Use the Intensity Slider to reduce the effect of yellowness without turning off the function completely.
- 🌙 Turn off Adaptive Protection if the phone changes colors depending on the lighting.
Adaptive protection is a feature that uses a light sensor to detect the time of day and turn on the filter, and it often doesn't work properly if you're in a room with bright artificial light but it's already night out, so the phone may decide it's time to turn the screen yellow, even though it's still light for your eyes at that time.
The influence of dark theme on color reproduction
Another common reason for color changes is the active Dark Theme, which includes MIUI 12/13/14 and HyperOS, which includes the Dark Theme Color Adaptation feature, which not only inverts colors, but can also add a light warm hue to the white background to reduce contrast and visual strain.
This setting is separate from the vision protection mode, although the visual effects may be similar. If you use a dark theme and see white become cream or beige, the problem is right here. Disabling this option will return pure white to backgrounds in settings and apps.
To remove the warm shade of the dark theme:
- Go to Settings. → Screen.
- Find the Dark Theme item and click on the settings gear next to the switch.
- Find the option Adapt dark theme colors (or More contrast in global versions) and turn it off.
Why does a dark theme change colors?
It's also worth noting that some wallpapers can have a built-in warm filter or just be done in yellow. When you change the theme, the system can automatically select wallpapers that visually change the perception of the screen.
Comparison of display modes on different models
Different models of smartphones Xiaomi, Redmi and POCO use different types of matrices (OLED, AMOLED, IPS). Color reproduction settings and night mode behavior may vary depending on the screen type and the shell version. AMOLED-Yellowness in night mode is more noticeable due to the deep black color.
The table below shows a comparison of night mode behavior on popular series of devices:
| Series of devices | Type of matrix | Features of night mode | Location of settings |
|---|---|---|---|
| Xiaomi 13/14 | AMOLED | Aggressive filter, strong shift to yellow | Settings → Screen → Protection of vision |
| Redmi Note | IPS / AMOLED | Moderate filter, depending on the model | Settings → Screen and brightness |
| POCO F/X | AMOLED | Often hidden in a Game Turbo or profile | Settings → Special. opportunities |
| Black Shark | AMOLED | Game profiles redefining settings | Game Space → Visual effects |
On Black Shark or POCO series gaming smartphones with Game Turbo activated mode, screen settings can ignore system settings. The game profile often has its own color reproduction mode, which can include a night filter regardless of the main system settings.
💡
If you’re an avid gamer, check the settings inside the Game Turbo app.There can be a separate visual profile activated that forcefully turns on warm tones to reduce fatigue during long sessions.
Problems with light sensor and autobrightness
Sometimes the night mode is turned on by itself because the light sensor is not working properly, and if the sensor is contaminated or closed with a low-quality protective glass, it can mistakenly identify the environment as dark, even when the lights are on in the room, which provokes the system to turn on the vision filter.
Autobrightness is closely related to these processes. When you turn off automatic brightness control, the system may stop correctly assessing whether it needs to turn on the night mode if it has been set to work in conjunction with the light sensor. However, manual brightness control is often the only way to make the screen shine the way you want it to.
Recommended checklist for diagnosing sensor problems:
- 🧹 Wipe the top of the screen where the sensor is located, from fat and dust.
- 🔦 Check if the sensor covers the case or the protective glass with a black frame.
- 📉 Turn off Auto Brightness in the notification curtain and check if color rendering changes.
- 🔄 Reboot the device to reset sensor calibration errors.
☑️ Screen diagnostics
In rare cases, calibrating the sensor through an engineering menu helps, but it requires caution. The average user just needs to make sure the top of the display is physically clean. If the problem persists only in certain applications, perhaps they use their own APIs to control brightness.
Use of engineering menus and hidden settings
For advanced users who don't find a solution in the standard menu, there is access to hidden settings through the engineering menu, a powerful tool that allows you to control the display settings at a deeper level, but using these features requires care, because incorrect changes can lead to incorrect display of colors.
To enter the engineering menu, open the Phone app and type a special code. For most Xiaomi devices, this is:
##6484##Or alternatively:
##4636##In the CIT menu that opens, you'll find a section that's associated with the display, which can be called Display, Screen or Color, and you'll find color tests and sometimes gamma mode switches. Be careful: changing gamma values can make colors unnatural forever until you reset.
⚠️ Warning: Do not change the values in the engineering menu unless you are sure of their purpose.Resetting the display settings through the normal interface after that may not be possible.
Also, some versions of MIUI have a hidden feature called Image Improvement or Vivid Display that can conflict with night mode. It's in advanced screen settings. Try switching the color scheme from Saturated to Standard or SRGB to see if the obsessive hue disappears.
