The night mode on Xiaomi smartphones is a useful feature that reduces eye strain in the dark by filtering the blue spectrum of the screen. However, not all Redmi 9 users like its work: someone notices color distortion, someone faces spontaneous switching on, and some simply prefer the original color reproduction. You can turn off the night mode in several ways, from standard settings to hidden options for MIUI firmware.
In this article, we’ll look at all the available methods for deactivating the feature, including disabling the notification bar, settings menu, and even resetting the screen. We’ll focus on the reasons why the mode can turn on automatically (for example, due to geolocation or schedule), and show you how to fix it. If you want to return the natural colors of the display or just get rid of the unnecessary feature, read on.
Night mode (or “vision protection”) in MIUI often works in conjunction with the light sensor and system services, which means that its behavior may depend not only on manual settings, but also on the time of day, battery level or even installed applications, for example, some programs (such as Google Health Services or Digital Wellbeing) can force the blue light filter to activate, ignoring your preferences.
It’s important to understand that Redmi 9 (M2003J15SC/M2004J19C) has a firmware-level night mode, so turning it off isn’t always intuitive. If you’ve tried to turn it off through quick settings, but it reappears, the problem lies in the schedule or automatic triggers. Next, we’ll look at each scenario separately.
Method 1: Disconnect via the notification panel (fast method)
The easiest way to deactivate night mode is to use the notification bar, which works if the feature has been manually enabled or scheduled, but not blocked by system policies.
1. Swipe your finger from top to bottom across the screen to open the notification curtain.
2. Find the Night Mode icon (usually depicted as a crescent with stars or an eye) If it's not there, swipe down again to turn the full panel around.
3. Tap the icon once. If it's illuminated in blue or yellow, the mode is active and will be turned off after you press it.
⚠️ Note: If the mode reappears after a few minutes after turning off, check the schedule in the settings (for this in the next section, MIUI 12.5+) You can reset your settings after rebooting.
- 🔄 Try holding the night mode icon for 2 seconds - this will open a direct link to the feature settings.
- 📱 No badge? Maybe it's hidden. Click on the pencil icon (✏️) In the notification panel and add it manually.
- ⚡ Quick Turn on: Twice tap the icon to activate the 1 hour mode (useful for temporary use).
Method 2: Completely disabling in screen settings
If the night mode is automatically turned on on schedule or because of the light sensor, it should be turned off in deep settings, this method is guaranteed to remove all activation triggers.
1. Open the Settings app (the gear icon on the home screen).
2. Go to Screen → Night Mode (or Vision Protection in some versions of MIUI).
3. Turn off the "Enable Night Mode" slider at the top of the screen.
4. Important! Scroll down and check the following parameters:
- Schedule → Select “No” (if it is “Down to Dawn” or fixed time).
Automatic turn on in low light → turn off.
- Color temperature → move the slider to the left stop (this will return natural colors).
⚠️ Attention: B MIUI 13/14 on the Redmi 9 There may be a hidden item Night mode inside the screen → Additional settings. If you don't find it, search by settings (the magnifying glass icon at the top).
Main switch switch switch switched off | Schedule set to "No" | Autoactivation on lighting turned off | Color temperature reset to minimum-->
Method 3: Disconnecting through Digital Well-being
Not everyone knows, but Xiaomi’s night mode can be controlled not only by system settings, but also by Google’s Digital Wellbeing module. If you’ve previously set time limits or turned on Sleep Mode, it could have activated a blue light filter.
1. Open Settings → Digital Well-Being and Parental Controls.
2. Go to the Dashboard tab (or Habits of Use).
3. Find the "Sleep Mode" or "Night Mode" block and turn it off.
4. Go back to the main Digital Well-Being menu and check Settings → Blue Light Filter (if any).
If night mode is on, turning it off should solve the problem, but note that MIUI sometimes duplicates features: even after deactivation in Digital Well-being, you may need to check the basic screen settings (see Method 2).
| Source of activation | Where to turn off | Note |
|---|---|---|
| System night mode | Settings → Screen → Night mode | The main trigger, works on schedule or manually |
| Digital well-being | Settings → Digital Well-Being → Sleep Mode | Can duplicate system settings |
| Light sensor. | Settings → Screen → Night mode → Autoactivation | It works in dark rooms. |
| Third-party annexes | Application settings (such as Twilight) | Check the overlay rights over other windows |
Method 4: Reset screen settings to factory
If the night mode persists, despite all the manipulations, the problem may lie in the failure of the MIUI configuration files. In this case, resetting the screen settings will help - this will return all display parameters (including night mode, adaptive brightness and color profile) to factory values.
1. Open Settings → System → Resetting.
2. Select Reset screen settings (not to be confused with a full reset!).
3. Confirm the action by entering the unlock password (if required).
4.After the reboot, check to see if the night mode has disappeared.
⚠️ Note: This method will reset all screen settings, including:
- Brightness and adaptive adjustment
- Color profile (e.g., Saturated or Standard)
- Font size and scaling
- Sensor sensitivity to touch
If the problem was a software failure, resetting will help, otherwise you have to look deeper, for example, in conflict with firmware or third-party modules.

Method 5: Disconnect via ADB (for power users)
If standard methods fail and night mode interferes with work, you can resort to disconnecting via ADB (Android Debug Bridge), which is suitable for users familiar with the command line and requires connecting the smartphone to the computer.
1. Install. ADB-Drivers on PC and enable Debugging by USB Redmi 9 (Settings) → The phone. → Version. MIUI → Click on version 7 times, then return to Additional Settings → For developers).
2. Connect the phone to the computer and type in the command line:
adb shell settings put global night_display_auto_mode 0
adb shell settings put global night_display_activated 03. Reset the device.
These commands force the night mode to be turned off at the system level, so if you want to return the function back, replace the 0 with 1 on both commands.
⚠️ Attention: Misuse of the right ADB Do not change other parameters unless you are sure of their purpose!
💡
Before working with ADB, back up your settings through Settings → System → Backup. This will allow you to quickly recover data when you crash.
Why does the night routine turn on on itself?
Many Redmi 9 users complain that the night mode is activated without their involvement, and the reasons for this are several, and most of them are due to automatic triggers in MIUI:
Geolocation and sunset/dawn time
The system can detect your location and turn on the blue light filter when it gets dark. Turns off in Settings → Screen → Night Mode → Schedule → No.
2. Illumination sensor
If you have the option Auto Turn on in Low Light, the mode will activate in dark rooms. It will turn off in the same place as the schedule.
3. Energy conservation
In Ultra-Economic or Battery mode, MIUI can force night mode to save charge. Check Settings → Battery → Modes.
Third-party annexes
Programs like Twilight, Night Shift, or even Google Assistant can control the blue light filter. Check the application rights in Settings → Apps → Permissions → Special Access → Overlay over other windows.
5. MIUI Update
After major updates (e.g., from MIUI 12 to MIUI 13), the screen settings may reset. Check the firmware version in Settings → About Phone.
💡
If you turn on the night mode yourself, check the schedule and the light sensor first, and 90 percent of the time, the problem is solved by turning off these two options.
Frequent Mistakes and How to Avoid Them
When trying to turn off night mode, users often make common mistakes that lead to the opposite result.
⚠️ Warning: Don't turn off Adaptive Brightness in the hope of getting rid of night mode. These functions work independently, and turning off one won't affect the other.
Mistake 1: Ignoring the schedule
Many people turn off night mode through the notification panel, but they forget to check the schedule. If it says "Down until Dawn", the function will turn on automatically.
Mistake 2: Using third-party color enhancers
Apps like Screen Filter or Lux Auto Brightness can conflict with the system night mode. Uninstall them or disable overlay rights.
Error 3: Reset all settings instead of resetting the screen
A full reset (Settings → Reset → Reset all settings) will delete all data from the phone. To solve the problem with night mode, only resetting the screen settings is enough.
Mistake 4: Missing MIUI updates
In older firmware versions (e.g. MIUI 11), night mode may not work properly. Update system via Settings → Software Update.
If you take these nuances into account, the shutdown process will be without surprises, the main thing is to check all possible sources of activation, not just the obvious settings.
