Modern smartphones like the Xiaomi Poco M3 have many features to protect users’ eyesight, one of which is called night mode or blue light filter, which is designed to reduce eye strain in the dark by changing the color temperature of the screen to warm shades. However, for many users, excessive yellowing of the display becomes a serious problem, preventing them from correctly perceiving colors when working with photos or watching videos.
Often, device owners are faced with a situation where the screen spontaneously changes color reproduction, which can be annoying and reduce productivity. Turn off night mode on the Xiaomi Poco M3 in several ways, since the MIUI system offers flexible schedule and intensity settings. In this article, we will discuss in detail all possible methods of deactivating the function so that you can return natural colors to your display.
The need for complete control over display settings is obvious, especially if you use a smartphone for graphic design or just prefer cold tones. We will look at standard settings menus, hidden developer options and script automation. Understanding these mechanisms will allow you to flexibly manage the screen at any time of the day without unnecessary discomfort.
What is a night mode and why it is needed
The night mode, often referred to as the MIUI’s “Read Mode” or blue filter, is a software color correction algorithm that cuts off the portion of the display’s radiation spectrum that is most active in the evening. Blue light suppresses the production of melatonin, the sleep hormone, so excess sleeptime can disrupt a person’s circadian rhythms.
Owners of the Poco M3 may notice that when this feature is activated, the interface becomes yellowish or amber. It's not a matrix defect, but a feature planned by the manufacturer. The system setup is designed to make it more comfortable for the eyes to use in low light conditions. However, during the day or when working with content that requires accurate color reproduction, this feature becomes useless.
💡
Use night mode only in low light so as not to distort the perception of colors in photos and videos.
There's a misconception that the blue filter is constantly running and it saves a lot of battery power. IPS-The screens that Xiaomi Poco is equipped with M3
The main way to disconnect through screen settings
The easiest and fastest way to remove yellow from the display is to use the standard system settings menu, which is suitable for most users and does not require advanced access rights. You need to open the main application menu and find the Settings icon, which usually looks like a gear.
Once you log in, you scroll down to the visualization section, and in different versions of MIUI, it can be called Screen or Display, and that's where all the key brightness, resolution and color profiles are concentrated, and find Read Mode or Eye Protection, depending on where your device is located.
☑️ Algorithm of action
Inside the menu, you'll see a switch that activates or deactivates the function. If it's on blue or green, it means the mode is active. Press it to turn off night mode. Immediately after that action, the colors on the screen should return to factory values. If that hasn't happened, check if the automatic mode is on schedule.
Scheduling and automation
Users often complain that the mode turns on itself, even if they manually turn it off, because of the activated automatic turn on on schedule. The MIUI system allows you to set time intervals during which the blue light filter will be forced to work, usually from dusk to dawn or a user-defined clock.
To remove automation, you need to go back to the Settings menu. → Screen. → Read mode. You should find a schedule or an automatic switch on here. This menu can preset the sunset to dawn or schedule options. You need to select the no option or simply put the shared automation switch in the inactive position.
- 🌙 From Dusk to Dawn: The mode is automatically turned on based on geolocation and time sunset/sunrise.
- ⏰ Scheduled: the user himself sets the start and end time of the function.
- 🚫 Turned off: The mode never automatically turns on.
Why does the regime turn on itself?
Importantly, resetting to factory settings can also bring back automatic activation if you've previously backed up a system with these settings. So after you restore data from the Mi Cloud or Google Drive cloud, always check your display settings again, which will help you avoid unexpected changes in color reproduction at the wrong time.
Using the Control Center for Quick Access
For those who prefer to control smartphone features without diving deep into the menu, there is a Control Center. In new versions of the MIUI shell installed on the Poco M3, the notification curtain is divided into two parts: notifications on the left and switches on the right. A swipe down from the upper right corner will open a quick settings panel.
Among the many icons, you need to find an icon that is signed "Read Mode" or an eye/book. If you don't see it on the first page, try swiping left to reveal the full list of available toggles. Clicking on an icon instantly changes its status: Active Mode is usually highlighted, inactive mode is gray.
| Action. | The result | Indicator |
|---|---|---|
| Single tap | On/off | Changing the color of the icon |
| Long pressing | Switching to settings | Opening the parameter menu |
| Icon swipe | No action. | — |
| Pressing in off condition | Activation of the regime | The appearance of a yellow hue |
| Quick switching | Instant system response | Visual response |
| Set-up of parameters | Access to deep settings | Going to the menu |
| Status check | Visual assessment of the condition | Color of the badge |
If the icon is not listed, you can add it through the edit button (usually a pencil icon or a tripod in the corner of the panel). In the list of available widgets, find Read Mode and drag it to the active zone, which will give you quick access to color temperature control in the future.
Hidden settings and developer mode
In some cases, standard methods may not work if the system has experienced software failures or experimental functions are activated. For advanced users, there is access to the developer menu. To get there, you need to go to Settings → About phone and quickly click on the version of MIUI seven times.
Once you have a “You’re a developer” message, go back to the main settings menu and select “Additional → For Developers.” This extensive list should look for a section related to color space simulation or night mode. However, beware: changing the settings here can affect other applications.
⚠️ Warning: Do not change the settings in the developer menu unless you are sure of their purpose.Resetting default values may require a complete reset of the device.
Also in this section, you can find the option "Simulate color vision abnormality." Make sure it has the value "Disabled." If you choose "Monochrome" or "Protanomalia," the screen will display colors incorrectly, which can be mistaken for night mode. Correct calibration is important for the proper operation of the interface.
Impact of Third-Party Apps and Themes
And remember, not only can you distort colors, but you can also have third-party software, and many book-reading apps, night-mode browsers, or launchers have their own built-in filters, and if you install a new theme from MIUI Themes, it can also force you to change the palette.
Check the list of newly installed applications. If a problem occurs after installing a program, try removing it or disabling Night Mode. Often, these apps ask permission to Overlay Other Windows, allowing them to change the view of the entire interface.
- 📚 Reading apps: often have their own blue filter.
- 🎨 Design themes: can change the system palette and brightness.
- 🛡️ Anti-Glare Apps: Create a Darkening Layer on top of the Screen.
To diagnose, try running your smartphone in safe mode, and if it's yellow, it's one of the apps you've installed that's to blame, and only system services are running in safe mode, making it easy to identify the culprit behind the color distortion.
💡
Third-party applications with overlay rights can overlap the system settings of the screen, creating the illusion of a malfunction.
Problems with light sensor and calibration
Sometimes it's not software settings, but hardware sensors. The Xiaomi Poco M3 has a light sensor that automatically adjusts brightness. If it gets direct light or is contaminated, the algorithms can misidentify the time of day and turn on night mode.
There is also a software error in screen calibration, in which case it helps to simply reboot the device or clear the cache of the system application Settings. Go to Settings → Apps → All Apps → Settings and click Clear Cache. This will not delete your data, but will reset temporary configuration files.
⚠️ Warning: If the screen flashes or changes colors chaotically, this may indicate a physical malfunction of the display plume, not a software error.
In rare cases, recalibration through the engineering menu helps, but entering there requires entering special codes into the phone book, which is not recommended without proper preparation. If none of the above has worked, you may need to flash the device or contact a service center to check the hardware.
