Xiaomi Redmi 9 is one of the most popular budget smartphones, but its night mode feature (or Read Mode) often raises questions among users. Some are faced with the fact that the screen turns yellow for no apparent reason, others can not find where to turn off the automatic blue light filter. In this article, we will discuss all possible ways to deactivate night mode, including hidden settings and workarounds for different versions of MIUI.
It’s important to understand that the night mode on Redmi 9 can work in two scenarios: either as a manual setup (on/off manually), or through the time or sunset/dawn scheduler. We’ll look at both options, and we’ll also explain how to turn off the feature permanently if it interferes with the color reproduction of the screen. If you notice that the interface has changed after the MIUI update, don’t worry, the instructions are relevant for versions 12.0, 12.5, 13 and 14.
1. Disconnect night mode through the basic settings
The most obvious way is to use the standard screen settings menu, which works on all versions of Redmi 9, regardless of regional firmware.
- Open the Settings app (the gear icon on the home screen).
- Go to the Screen section.
- Select Night Mode (or Read Mode in some firmware).
- Move the slider to the off position. or uncheck the box from the option Automatically.
If you don't have Night Mode on your menu, check the Additional Screen Settings section - sometimes the feature is hidden there. Also note the shortcuts in the notification curtain: it's possible that the mode is enabled through quick settings (swipe down from the top edge of the screen).

2. Scheduler setting: why the mode turns on itself
Many Redmi 9 users complain that night mode activates itself, even if it is manually disabled, the reason being the scheduler, which is by default tied to sunset and dawn times, to turn off automatic activation:
- Go to Settings → Screen → Night mode.
- Click on the schedule (or scheduler).
- Select No or Off to deactivate Automotive.
- If you have the option from sunset to dawn or time, remove the mark from them.
On MIUI 13+ firmware, the scheduler can be hidden under the "Sleep Mode" item in the "Digital Well-Being" section. If you don't find it in the screen settings, check this section. And some users note that once you reset the settings to the factory, the scheduler is activated again, a feature of MIUI that can only be fixed by manual adjustment.

3. Resetting screen settings to factory
If the night mode does not turn off through standard methods, system settings may have gone wrong, in which case resetting the screen settings (without data loss) will help:
- Open Settings → System and device → Additional settings.
- Select Settings Reset.
- Click Reset Screen Settings (not to be confused with a full phone reset!).
- Confirm the action and restart the device.
This will bring all display parameters back to factory, including color temperature, adaptive brightness and night mode. Note: after reset, you may need to recalibrate the screen (in the same settings).
⚠️ Warning: If the night mode is activated again after the reset, check out third-party apps (e.g. f.lux or Blue Light Filter) that may conflict with system settings. MIUI.
Disconnection through Developer Modes (for power users)
In some cases, the night mode on Redmi 9 is controlled by hidden settings that can only be changed through the developer menu.
- Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
- Go back to the main settings menu and open a new section for developers.
- Find the item Disable all night mode settings (or Night Display in English firmware).
- Reboot the phone.
If there is no such item, try changing the parameter. force_dark (It is responsible for dark topics, but sometimes affects color temperature):
adb shell settings put global force_dark 0This command should be entered through ADB (Developer Tool), and be careful that the wrong actions can lead to interface failures.

5 Problems After MIUI Update: What to Do
Redmi 9 users often find that the night mode starts to work differently after the MIUI update, for example, in MIUI version 14 the function was integrated into the digital well-being system, and in MIUI 12.5 it was called "Vision Protection" to adapt to changes:
| MIUI version | Where to look for night mode | Features |
|---|---|---|
| MIUI 12.0 | Settings → Screen → Night mode | There is a separate time planner. |
| MIUI 12.5 | Settings → Screen → Protection of vision | Geolocation binding (sunset/dawn) added |
| MIUI 13/14 | Settings → Digital Well-Being → Sleep Mode | Function combined with notification limitation |
If after updating the night mode began to work unpredictably (for example, it turns on during the day), try:
- 🔄 Reset the screen settings (see Section 3).
- 📱 Remove the cache of system applications (Settings) → Annexes → Application management → Three points. → Show system-based → Settings/Screen).
- 🔧 Remove the update through Settings → The phone. → Updating the system → Three points. → Select the update package (if the backup of the old firmware is saved).
6. Alternative solutions: if nothing helps
If standard methods do not work, consider the following options:
- 🛠️ Custom firmware installation: For example, LineageOS or Pixel Experience do not have a built-in night mode from Xiaomi. Note that this requires unlocking the bootloader and may take away warranty.
- 📱 Use of the ADB-Complete Disabling Features via Console: Adb shell settings put secure night_display_activated 0 adb shell settings put secure night_display_auto_mode 0
- 🔍 Virus check: Some malicious apps change screen settings. scan your phone through Malwarebytes or Dr.Web.
On Redmi 9 with European firmware (EEA), night mode can be tightly tied to Google services, in which case only disabling sync with Google account in account settings will help.
⚠️ Attention: When in use ADB-commands or custom firmware are at risk of damaging system files.We recommend backing up through Settings → Additionally. → Backup and reset.
💡
If night mode is only enabled in certain apps (like Chrome or Instagram), check the settings of these programs. Some of them have built-in blue light filters that are independent of the system.
