Redmi and Xiaomi smartphones feature advanced vision protection systems that automatically adjust the color temperature of the display. On the Redmi 9, this feature is often turned on by default to reduce eye strain in the evening. However, many users are annoyed by the yellow tint of the screen, which distorts the colors when watching photos or videos.
In this article, we will discuss how to turn off the night mode on the Xiaomi Redmi 9 to return the natural color reproduction. You will learn not only about the standard settings, but also about the hidden features of MIUI that allow you to flexibly manage the time of the blue light filter.
Sometimes users confuse night mode with energy saving mode or dark interface theme. It is important to understand the difference, as they turn off in different sections of the menu. Below we will provide a comprehensive guide that will help you adjust the screen exactly as convenient for you.
What is Reading Mode and How Does It Affect the Screen?
The feature, commonly referred to as "night mode," is officially called "Read mode" in the MIUI shell, and its primary purpose is to filter the blue spectrum of the display's radiation by replacing it with warmer yellowish tones, which reduces melatonin production and makes it easier to fall asleep if you use your phone before bed, but this effect can be very undesirable during the day or when working with graphics.
The Xiaomi Redmi 9 has a number of options for this filter, so you can choose a full monochrome display that mimics electronic ink, or just a warm color scheme, and you can manually adjust the intensity of the effect, which gives you more control over the look of the interface, and if you just want to remove the yellowness, you just need to switch to a standard profile.
It's worth noting that activating this option will affect not only system menus, but all third-party apps, as browsers, games and social networks will also be displayed in warm colors, which can lead to you not noticing how the colors in the photo you're editing have distorted, so many prefer to keep this feature off.
⚠️ Warning: Long-term use of heavily warm screen tones can distort your perception of color, so when working with graphics or photos, be sure to turn off filtering.
Understanding color temperature helps you better customize your device to your needs. The Redmi 9 screen can display millions of shades, and artificial spectrum restriction narrows this range. If your eyes are not tired of the usual glow, you better leave the default settings.
Step-by-step instructions for turning off the blue light filter
To quickly remove the yellow tint, you need to get into the advanced display settings. MIUI interface may vary slightly depending on the firmware version, but the logic remains the same for all smartphones of the brand.
First, unlock the device and find the Settings icon on your desktop, which is usually located at the top of the screen or in the dock bar at the bottom, and we need the system partition, not the specific application settings.
☑️ Algorithm of the deactivation mode
In the menu that opens, look for the Screen (or "Display"). Inside this section, we're interested in Read Mode. When you click on it, you'll see the switch at the top of the screen. If it's active (burning green or blue), just tap it to turn it off.
Sometimes users forget that the mode has a schedule. Even if the main switch is off, the phone can automatically turn on the yellow screen at a given time. So be sure to check the timer settings in the same menu to rule out automatic activation.
- 📱 Open the settings of your smartphone.
- 🖥️ Go to the Screen section.
- 📖 Select the option Reading Mode.
- 🚫 Turn the switch to the off position.
After doing these actions, the colors on the screen should become cooler and brighter. If this does not happen, perhaps activate the energy saving mode, which can also mute the colors. Check the appropriate section in the battery settings.
Scheduling and automation
One of Xiaomi's most useful features is the flexibility of adjusting the filter time, so you can not turn off the mode completely, but adjust it so that it only turns on at night, which is the perfect trade-off between eye comfort in the daytime and eye protection in the evening.
In Read Mode, find the Schedule. There are several scripts available here, so you can choose to turn on "Down to Dawn" using geolocation, or set specific hours, like 22:00 to 7:00, so you can forget about manual switching.
The Low Light Automatic Activation option is also available, and the light sensor on Redmi 9 analyzes the environment and, if the room gets dark, offers or immediately turns on the warm spectrum, and if you are concerned, this option should be manually deactivated.
| Schedule type | Description of the work | Recommendation |
|---|---|---|
| Included. | Regime is active all the time. | For sensitive eyes |
| From dusk to dawn | Depends on | The best option |
| Predicted time | According to your schedule. | For strict security |
| Off. | The regimen's down. | For designers. |
Using geolocation to determine the sunset time requires permission to access the location, without which the phone will not be able to correctly determine the time of sunrise and sunset, and the automation will not work properly.
Control via Quick Access Panel
You don't have to go into the deep settings menu every time. MIUI allows you to control the basic functions of the screen through the notification curtain, which greatly speeds up the switching between modes.
Swipe down from top to bottom to open the control center, find an icon with an eye or an "A" (depending on the version of the shell), and if you can't see that icon, it may be hidden.
To add a button, click on the edit icon (usually a pencil or three dots) in the corner of the panel. In the list of available items, find Read Mode and drag it to the active zone. You can now turn the filter on and off with one touch.
💡
Add the “Read Mode” button to the top of the notification curtain for instant access without going into the settings.
This method is especially useful when you are in an app that looks bad in yellow, and you need to quickly return normal colors. However, remember that this is a temporary solution if you have a rigid schedule in the settings.
Specific settings for Redmi 9 and MIUI 12/13
Redmi 9 is powered by Helio processor G80 uses IPS-Unlike the matrix. AMOLED-The screens of flagship models, there is no PWM brightness control, but color reproduction settings remain critical. MIUI 12 and 13 additional profiles are added.
In the Color Style section (located next to the read settings), you can select a Standard, Saturated or Classic profile. Selecting a Standard profile often helps to remove excessive yellowness, even if the read mode is formally disabled.
Some users encounter a bug when the firmware update resets and the yellow filter turns on on itself, in which case it is recommended to check the Advanced Settings section -> Unlimited Mode (or similar), as there may be duplicated some screen management functions.
⚠️ Note: Some global firmware versions may have a menu item called "Comfort Mode" or "Eye Protection", which is a complete analogue of Read Mode.
If you use third-party launchers or themes, they can overlap the system color settings. Try using the standard Classic theme to make sure the interface isn't visual.
Addressing common problems
Sometimes the user has done all the actions, but the screen is still yellow or dim, and this may be due to hardware constraints or software conflict. Let's look at the underlying causes.
The first reason is active energy saving mode. When the battery drops below 20 percent, Xiaomi automatically limits brightness and changes the color scheme to save energy. Check the battery icon in the corner of the screen.
Hidden Developer Settings
The second reason is that there's a third-party book or eye protection app installed that takes precedence over system settings. Check the list of recently installed programs. If the problem doesn't work, resetting all settings to factory settings will help, but that's a last resort.
- 🔋 Check if the energy saving mode is included.
- 📱 Remove third-party filter apps.
- 🔄 Update the system to the latest version.
- 🛠️ Reset the screen settings to factory.
It is also worth mentioning that the IPS-If the yellowness only appears when you look at the phone from the side, it's a physical feature of the matrix, not a software bug.
💡
If the screen only yellows at low brightness, this is a feature. IPS-Matrixes, not software configuration.
