Why the night mode turns on on on its own and how to fix it
The night mode (or “Read Mode”) on the Xiaomi Redmi Note 9 Pro is a useful feature that reduces eye strain by filtering blue light. However, many users experience a situation where the screen suddenly turns yellow for no apparent reason, due to automatic schedules, geolocation triggers or MIUI failures.
In this article, we will discuss all possible ways to turn off night mode, from basic to hidden, you will learn how to remove the yellowness of the screen through the notification panel, display settings, and what to do if the mode turns on on on itself despite all your efforts. We will focus on issues after updates MIUI 12/13/14, where the logic of the function has changed.
Important: on the Redmi Note 9 Pro (models) joyeuse/curtana) nighttime may conflict with Adaptive Brightness and Vision Protection. If yellowness remains after switching off, check these parameters separately.
Method 1: Quickly shut down via notification panel
The easiest method is to use the Quick Settings Panel, which works on all versions of MIUI, including custom firmware:
- Swipe your finger down to open the notification panel.
- Find the Night Mode icon, or the moon with the stars or the eye, and if it's not there, click on the pencil and add the switch to the active one.
- Slip the icon once to instantly turn off the blue light filter without saving settings.
⚠️ Note: If the night mode is activated again after the phone restarts, then the automatic schedule is turned on in the settings.
Method 2: Completely disabling in the display settings
To permanently remove the night mode, you need to deactivate it in the settings menu:
- Open the Settings → Display.
- Select Night Mode (or Read Mode in older versions of MIUI).
- Turn the slider to the "Off" position.
- Turn off the options: 🌙 "Automatically scheduled" (remove on/off time). 📍 "Automatically positioned” (Downset/Dawn geolocation triggers). 🔄 "Adaptive brightness" (may conflict with manual settings).
If the “Schedule” or “Location” items are inactive, they are managed by a third-party application (e.g. Google Digital Wellbeing). Check the settings in Settings → Applications → Permissions Management → Special Access → Do not interrupt.

Method 3: Reset the display settings (if the mode does not turn off)
If night mode continues to activate despite all manipulations, the cause may lie in corrupted system files, in which case the reset of the screen settings will help:
- Go to Settings → Display → Additional.
- Select "Reset Display Settings" (or "Restore Default Values").
- Confirm the action. It'll go back to factory parameters: 🎨 Brightness and contrast. 🔍 Color profile (sRGB, Saturated, etc.). 🌓 Night mode and vision protection.
⚠️ Warning: Resetting does not affect wallpaper and theme, but will return adaptive brightness and autocontrast to standard values. After the procedure, it is recommended to manually adjust the color profile in Settings → Display. → Color mode.
What if the reset didn't help?
Table: Difference between nighttime and vision protection
| Function | Night mode. | Protection of vision |
|---|---|---|
| Purpose | Filtering blue light for eye comfort | Reduce screen flicker and optimize color temperature |
| How it's going to work. | Manual switchboard, schedule, geolocation | Only manually in Settings → Display → Vision Protection |
| Impact on color reproduction | Strong yellowness (regulated by a slider) | Slight displacement in warm tones, almost imperceptible |
| Conflicts | Can conflict with adaptive brightness | It works independently of other functions |
| Energy consumption | Small increase in battery consumption (due to color processing) | It does not affect autonomy. |
If you've turned off night mode, but the screen is still turning yellow, check if your vision protection is activated, and these functions are often confused, even though they work differently.
Hidden settings: disabling through MIUI Launcher
In some versions of MIUI (especially 12.5 and later), night mode can be turned off via the hidden launcher menu, which is useful if the standard settings do not work:
- Press and hold the empty area on the main screen.
- Select "Home Screen Settings" (or "Luncher Settings").
- Go to the "Additional" or "Screen" section.
- Find the "Night Mode" or "Blue Light Filter" option and deactivate it.
⚠️ Attention: At the launcher MIUI 14, this item may be called "Dark Theme" -- not to be confused with night mode -- dark theme changes the interface design, but it doesn't affect the color rendering of the screen.
💡
If night mode is only enabled in certain apps (like Chrome or YouTube), check their internal settings. Some programs have their own blue light filter, independent of the system.
What to do if the night mode turns on on itself
If the mode is activated without your participation, the reasons may be as follows:
- 🕒 Schedule failure: Remove all time slots in night mode settings and reboot your phone.
- 📱 Application conflict: Programs like f.lux, Twilight, or Google Digital Wellbeing can override system settings. Delete them or deny access to display settings.
- 🔄 Update MIUI: After major updates (for example, with the MIUI 12 by 13) resets some settings. Check settings after update.
- 🔋 Energy Saving Mode: In Ultra-Economic or Super-Energy Saving mode, vision protection can be automatically enabled.
For diagnosis:
- Run your phone in Safe Mode (press the power button → Safe Mode) If the problem has disappeared, the third-party app is to blame.
- Check system logs through Settings → About Phone → Error Report (select System Logs and find mentions of NightDisplay or ReadingMode).
💡
If night mode is only turned on when connected to Wi-Fi or mobile network, the problem may be timing. Check date and time settings in Settings → Additional → Date and time and turn off automatic synchronization.
