How to remove the night mode on Xiaomi Redmi Note 9: all working methods

Xiaomi Redmi Note 9 is one of the most popular smartphones in the budget segment, but its night mode feature (or "Eye Comfort" in MIUI) does not always work as you would like. Many users face a situation where the screen suddenly turns yellow during the day, colors are distorted and automatic settings are confused. If you too are tired of the constant yellowish shade of the display that interferes with graphics, watching videos or games, this article is for you.

We'll explore all the ways you can turn off the night on the Redmi Note 9, including hidden MIUI settings, auto-scheduling bypasses, and even radical methods for stubborn devices. And explain why sometimes the mode turns on on itself and how to avoid it. Whether you use your smartphone for work, school or entertainment, after reading it, you can return the screen to natural colors in two clicks.

Why does the night routine turn on on itself?

Before you turn it off, you should know what activates it. On the Redmi Note 9, night mode can start automatically for several reasons:

• 🕒 Timetable by time — MIUI defaults to a schedule from 22:00 to 7:00, but it can be accidentally knocked down when you update the system.
• 🌅 Light sensor – the smartphone analyzes the level of light in the room and turns on the filter in dim lighting.
• 🔄 Resetting settings - after updating the firmware or resetting to factory parameters, the mode can be activated with default parameters.
• 📱 Application conflict – some programs (e.g., Twilight or Night Shift) may duplicate the system function.

Interestingly, the Redmi Note 9 (model M2003J15SS) has a MIUI night mode, not Android, which means that the standard ways to turn off Settings → Display may not work if the system is “gone out.” In such cases, you have to use workarounds — these will be discussed further.

Method 1: Disconnect via standard MIUI settings

The most obvious method is to use built-in system options, and it is suitable for most users who have night mode activated due to a schedule or accidental pressing.

Step instructions:

1. Open the Settings app (the gear icon on the desktop).
2. Go to the Display section.
3. Slip on Night Mode (or Eye Comfort in new MIUI versions).
4. Move the slider to the off position. or uncheck the box with Automatic.
5. If the Schedule option is active, click on it and select No.

Display settings open |Night slider in off position.|Automatic schedule disabled |Light sensor checked (if any)

On some Redmi Note 9 firmware (e.g. MIUI 12.5), the item may be called Read Mode or Vision Protection. If you don't find the right option, try searching by settings (the magnifier icon at the top of the screen) and entering the night query.

⚠️ Note: If after the switch off, the mode is activated again through 5-10 In the minutes, the problem may be a system cache failure, in which case it will help to restart the device or reset the display settings (more about this in the next section).

Method 2: Reset the display settings to factory

When a standard shutdown doesn't work, it's worth returning the screen settings to their original values. This method doesn't affect personal data, but resets all user brightness, color temperature and schedule settings.

How to perform the reset:

1. Go to Settings → Display.
2. In the upper right corner, press three dots (⋮) and select Resetting Settings.
3. Confirm the action by pressing OK.
4. After reset, open the night mode settings again and make sure it is deactivated.

If there is no Reset option, use an alternative method:

Settings → About phone → All settings → Resetting settings → Resetting display settings

💡

After reset, check if the security mode in the Security app has been activated. Sometimes MIUI duplicates the settings in different sections.

This method helps in 80% of cases when night mode is turned on spontaneously due to a software failure.

Method 3: Disconnection through Developer Modes

For power users who aren’t afraid to dig into system settings, there’s a more radical method — turning off night mode through developer mode — that will help if MIUI ignores standard commands.

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone. 7 times click on MIUI Version until the notification appears You became a developer!.

For developers

Disable all overlays

Disable HW overlays

Reset the device.

After the reboot, check the night mode settings again - it should be turned off.

⚠️ Warning: Turning on the option to disable all overlays may cause the screen to flicker in some applications. If you notice artifacts, return the setting to its original position.

If this seems too complicated, try the alternative via ADB (Android Debug Bridge).
