Xiaomi’s Redmi line of smartphones are equipped with advanced vision protection systems that automatically change the color temperature of the screen. Redmi 9 users often experience an unnatural yellowish tint, especially in the evening, due to the activation of the Night Mode feature, designed to reduce eye strain.
However, for many users, this blue-spectrum filtering is redundant or simply annoying when viewing content, and it is necessary to quickly find settings and deactivate this option, returning the screen to its usual brightness and color reproduction. In this article, we will discuss in detail all ways to control this parameter in the MIUI shell.
We'll look at not only the standard shutdown, but also the work with the schedule, which can include the mode automatically, and also focus on related features, such as Read Mode, which is often confused with the night filter, understanding these nuances will allow you to fully control the appearance of your device.
What is a night mode and why it is needed
Known as Night Mode or Read 2.0 in Xiaomi terminology, the feature is a software filter that blocks some of the blue spectrum emitted by the display matrix, and is thought to inhibit melatonin production, which can make it difficult to fall asleep when using the gadget before bedtime.
Redmi 9 has several options for how it works: Basic mode simply shifts the color temperature to the warmer side, making the image yellower; more advanced algorithms can mimic the texture of paper or change the contrast of text for ease of reading books; it is critical to understand the difference between a simple blue filter and a full read mode, since they turn off in different menus.
Despite the developers’ good intentions, many users prefer to disable this feature, distorting colors can interfere with photo work, watching videos or simply cause discomfort due to the unnatural color reproduction of the interface, and the constant operation of the filter can slightly affect the autonomy of the device.
MIUI offers flexible settings to adapt screen performance to your individual preferences, so you can choose the degree of "warmth" of the screen or completely remove any restrictions, and it's important to understand the logic of the menu so you don't get confused by similar options names.
- 🌙 Reduces the radiation of the blue spectrum to protect the eyes in the dark.
- 🎨 Changes the color temperature of the screen, making the colors warmer.
- 📚 Includes additional filters for comfortable reading of texts.
- ⏰ It can be activated automatically on a schedule or sunrise.
Quick shutdown through notification curtain
The easiest and fastest way to remove the yellow tint is to use the control panel. Xiaomi smartphones offer easy access to frequently used features without diving deeply into the settings, which is especially true if the mode is switched on accidentally or on schedule.
To do this, you need to unlock the screen and swipe from top to bottom of the display, and you'll open a control center where the key function switches are located, and among the many icons you'll need to find an item called Read Mode or Night Mode.
If you don't see the icon on the first page, swipe left to reveal the full list of available switches.Clicking on the active icon instantly deactivates the filter.The screen will immediately return to standard color rendering.
☑️ Checking the Quick Menu
Sometimes the icon may not be in the quick access panel, which can be added by clicking on the edit button (usually a pencil icon or three dots in the corner of the switch menu), find the desired switchboard in the list of available items and drag it to the active zone.
This is a good way to use it in a situational way, where you have to temporarily remove the filter, but it doesn't stop automatic activation on a schedule if it's set up in deep settings, and you'll need more detailed adjustments to fully control the behavior of the screen.
Setting the parameters in the screen menu
For deep configuration, you have to go to the system menu, and that's where all the major display controls are, and the path to that is standard for the MIUI shell, but it can vary slightly depending on the firmware version.
Open the Settings app on the home screen. Find the Screen (or Display) section. This is where all the parameters related to brightness, refresh rate and color profiles are concentrated. We're interested in the visual protection subsection.
Inside the menu, you'll find Read Mode, and when you go to it, you'll see the activation switch. If it's on, the slider will burn blue. Put it inactive to turn off the filter completely.
And there's additional settings available here, if you don't want to give up the function completely, you just want to change the behavior, you can adjust the filtering level, you can choose the monochrome mode, you can change the activation mode, and these options allow you to fine-tune the screen to your needs.
- 🔍 Accurate adjustment of color temperature by slider.
- 📅 Managing automatic switching over time.
- 🌗 Choosing between normal and improved reading.
- 📱 Set up exceptions for individual applications.
Notice the tab or the Settings button inside the read menu, and the Planner option may be hidden there, which is often the reason why the screen turns yellow at certain times of the day, even if you have turned off the main switch manually.
Scheduling and automation management
One of the most common reasons for the yellow filter to suddenly turn on is the activated scheduler, and MIUI allows you to set time intervals in which night mode is forced to turn on, which is health-friendly, but can be annoying if you're working with color.
From Settings → Screen → Read Mode, find Schedule Turn on. If the switch is active, click on it for detailed settings. You will see two main options: “Downdust to Dawn” and “Time.”
The Sunset to Dawn option uses the geolocation data of your Redmi 9 to determine the day-night shift time, which is a dynamic mode that shifts every day. If you don't need automation, just turn off this switch.
Why does the regime turn on itself?
Time Mode allows you to set specific hours, such as 21:00 to 07:00. Check the time stamps set. If the current time falls within this interval, the mode will turn on automatically, ignoring your manual attempts to turn it off through the curtain.
⚠️ Warning: If you have turned off reading mode but the screen still turns yellow at certain times, be sure to check the alarm settings or Sleep profile. MIUI Sleep profile may force a blue filter.
To completely disable automation, switch the switch to turn on schedule in the "Off" position. After that, the screen will behave predictably and change colors only on your direct command.
Difference between night mode and reading mode
Users often confuse Night Mode (blue filter) and Read Mode (paper imitation) with Xiaomi’s interface, which can be combined into a single menu, but technically they work differently.
Night mode (or blue filter) simply changes the white balance by adding a yellow or orange hue. It's a global change that affects all the pixels of the screen evenly. It doesn't change the contrast or saturation of colors other than blue spectrum.
Reading mode is a more aggressive setup, which can put the interface in black and white, increase contrast, and add noise that mimics a paper page, which is designed specifically for applications like MI Reader or browsers.
| Parameter | Night mode (Filter) | Reading mode (Books) |
|---|---|---|
| Main objective | Reducing the burden on the eyes | Imitation of a paper book |
| Impact on colours | Shift to the yellow spectrum | Partial or complete monochromaticity |
| Where to find out. | Settings → Screen | Settings → Screen → Reading Mode |
| Automation | Available (time/sunset) | Often manually or in an app |
To turn off the paper simulation, you need to select Classic over Enhanced from the read menu or completely disable the function, and in some firmware versions, these settings are spread out in different tabs within the same menu.
If your goal is simply to remove yellowness, make sure you don’t accidentally activate black and white mode in special features.Settings path → Advanced settings → Special features → Visual leads to Color correction, which can also change the look of the screen.
Problem Solving: If the mode is not turned off
There are situations where standard methods don't work: the switch is off, the schedule is not, and the tetap screen is yellow, which may indicate a software failure or a setting conflict, and in such cases, consistent diagnosis is required.
First of all, try rebooting your device. On Android and MIUI, it solves 90 percent of the interface's time glitches. Press and hold the power button, then select Reboot.
If the reboot didn't work, check if the power saving mode is on. When the battery is low, Redmi 9 can automatically limit brightness and change the color gamut to save energy. Turn off the energy saving mode in the notification curtain or in the battery settings.
💡
Periodically clean the cache of the application "Security" and "Settings" if the menu settings of the screen is not working correctly or freezes.
It's also worth checking out third-party apps. Some book readers or video players have their own built-in filters that override system settings. Open that app and check its internal menu.
⚠️ Warning: If the screen turns yellow after a phone drop or moisture hits and software methods do not help, the display plume or controller may be damaged.
In a pinch, you can reset all settings to factory settings, which will return the phone to its original state by removing all user configurations, and make sure to back up important data before doing so.
💡
If the software shutdown does not help, the problem may be in hardware or a third-party software conflict requiring more in-depth diagnosis.
