Owners of the popular Xiaomi Redmi 4X smartphone often face a situation where the device’s screen turns yellowish or warm, especially in the evening. This is not a matrix malfunction or hardware failure, but is the work of a system function designed to reduce the load on the user’s vision. In the MIUI interface, this tool is called Night Mode or Reading Mode, and it is automatically activated on a schedule or when a certain level of light is reached. For many users accustomed to cold, crystal clear shades of white, this behavior can be an unpleasant surprise, disruptive content perception.
Disabling this option is not a complicated process, but the location of the switches can vary depending on the version of the installed firmware MIUI (Global, China or Russia).In this article, we will discuss in detail all possible ways to deactivate the yellow filter, adjust the color profile and eliminate automatic inclusion, which often annoys users when viewing photos or working with documents. Understanding the adaptive brightness and software filters will allow you to fully control the appearance of the display of your gadget.
Before you start changing system parameters, it is important to note that the complete absence of a warm filter in the dark can lead to faster eye fatigue. However, if you prefer maximum color reproduction and clarity of text, customizing the system to your needs is absolutely justified. We will consider not only standard methods of turning off through the settings menu, but also touch on the nuances of the operation of light sensors, which can affect the activation of the mode.
What is Night Mode and Why You Need It on Redmi 4X
The feature, known as Night Mode or Read Mode, was introduced by the developers. MIUI Minimize the emission of the blue spectrum of light that emits IPS-The blue light, especially in low light, inhibits the production of melatonin, a hormone responsible for regulating circadian rhythms and sleep. The system’s algorithm automatically shifts the color temperature of the screen to the warmer side, making the colors softer and more pleasant to perceive in the dark, especially for those who like to read e-books or flip through social media before bedtime.
Despite the creators’ good intentions, the Redmi 4X’s implementation of the feature sometimes works too aggressively. Yellow can appear not only in the evening, but also in the afternoon if the phone is in a pocket or bag where the light sensor detects a lack of light. In addition, for designers, photographers and just lovers of juicy colors, this filtering makes the image unnatural and faded. Understanding the principle of the color profile helps to consciously approach its setting or completely turning it off.
It's also worth noting that the names of the items may vary slightly from one version of the MIUI shell, some called Night Mode, others called Read Mode, but the bottom line is that you can program a filter over the display image, and if you want to bring back the natural, factory-like colors, you need to find the appropriate switch in the display settings section.
Step-by-step: disabling through display settings
The easiest and most reliable way to remove the yellow tint is to use the standard system settings menu, which is suitable for the vast majority of users and does not require installing third-party software or having root rights. Let's go through the steps that will help you return the cold tones of the screen.
First of all, unlock your Xiaomi Redmi 4X and find the Settings icon (usually a gear) on your desktop. In the menu that opens, you need to scroll down to the section responsible for the screen. Depending on the version of MIUI, it can be called Screen or Display. This is where all the basic visualization options are concentrated.
☑️ Algorithm of the deactivation mode
Inside the Screen section, you'll need to find Read Mode (or Night Mode), and when you enter it, you'll see a switch that's likely in the active position. To turn off filtering, just move the slider to Off. Then the screen should instantly change the color rendering to become cooler and brighter. If the yellowness remains, check if the Schedule option is activated there, which we'll talk about later.
⚠️ Warning: After turning off the screen reading mode, the colors on the screen may appear unnaturally bright or "acid" in the first minutes.
Schedule setting and automatic switching on
Often users complain that the mode turns on on itself, even if they turn it off manually, the secret lies in the automation function, the system allows you to adjust the filter schedule to turn on at certain times of the day or when you run specific applications.
In the same Read Mode menu, find Schedule or Schedule, where you can activate Sunset to Dawn, and then use your location and time of year to determine when to turn on the yellow filter, and if you don't want to be dependent on the sun, select Set Time and set the time interval when you really need it, or turn off the automation entirely.
Also worth checking is the list of apps. MIUI can only enable read mode for certain programs, such as a browser or Reader. If there are any extra apps on this list, the mode will activate every time they run. Clear the list or turn off this feature to have full control of color temperature at any time.
For those who like to read but don't want to have a yellow hue throughout the interface, there's a trade-off: You can leave the mode off globally, but only turn it on for a particular book-reading app, which will keep the juicy colors in games and gallery, but take care of your eyes during long reading.
Correction of color reproduction and color profiles
In addition to night mode, color perception on the Redmi 4X is influenced by the color profile chosen. In the screen settings, you can often choose between Standard, Saturated and Classic modes. Sometimes users confuse saturation settings with night mode, although technically these are different options.
The Saturated Colors mode makes the picture brighter and contrasting, but can distort real shades, making them excessively warm or cold depending on the calibration of the matrix. The Standard or Classic mode strives for maximum color accuracy of sRGB. If after turning off the night mode, the colors still seem strange, try changing the profile.
| Parameter | Description of the influence of the screen | Recommendation |
|---|---|---|
| Night mode. | Adds a yellow filter, reduces the blue spectrum | Turn off for precise colors |
| Brightness | Regulates the power of the matrix illumination | Set up for comfort. |
| Color profile | Changes the scale and saturation of shades | Select "Standard" |
| Dark subject matter | Makes the interface background black | At the discretion of the user |
It's important to understand the difference between a software filter and a hardware matrix. Redmi 4X has a high-quality screen, but its calibration from the factory can be shifted to the warm side, in which case no settings will make the picture perfectly cold, but turning off the unnecessary filters will bring it as close to normal as possible.
💡
To quickly check the color rendering, open the full screen white image in the gallery. If you see a clear yellow or pink hue, check the color profile settings.
Problems with the light sensor and their solution
One of the common causes of yellow tinting spontaneously is that the light sensor is not working properly, and this little sensor next to the speaker reads the light level in the room, and if it's contaminated or covered with a protective film, the phone can think it's nightfall and activate adaptive mode.
Check the top of the screen for dirt, greasy spots or bubbles from the protective glass. Even a small obstacle can distort the sensor readings. Wipe the speaker area with a soft cloth. It is also worth checking whether the Auto Brightness feature, which often works in conjunction with night mode, is enabled. Turning off autobrightness can solve the problem of sudden change in the color of the screen.
⚠️ Attention: If the light sensor is physically damaged (for example, after a fall), the software settings may not help.
Calibration of the sensor through the engineering menu helps in some cases, but for the average user it is safer to simply turn off all automatic scenarios related to lighting, which ensures that the screen behaves predictably, regardless of the external conditions.
Use of third-party applications and advanced settings
If standard MIUI settings aren't enough, there are alternative ways to control the screen. There are a lot of blue light management apps available on the Google Play Store, like Twilight or Blue Light Filter, that can intercept color control even when the system mode is off.
Check the list of installed applications. If you have previously installed these utilities, they may conflict with system settings or work in the background. Removing or disabling such programs often returns normal color reproduction. In addition, some launchers and themes can force the color scheme of the interface to change.
Engineering menu Redmi 4X
Sometimes the problem is updating the system, because after you upgrade to a new version of MIUI, the old settings may conflict with the new algorithms, so you should recheck all the screen menu items, because the configuration structure may have changed.
