How to completely disable the night mode on Xiaomi Redmi 9 NFC: all ways

Night mode on Xiaomi Redmi 9 NFC is a useful feature for protecting vision, but not all users like the yellowish shade of the screen. Especially annoying is automatic turn on on on schedule or in low light. In this article, we will discuss all possible ways to turn off night mode, including hidden MIUI settings and workarounds for persistent cases.

Redmi 9 NFC (codename gauguin) runs on MIUI 12/13 with Android 10/11. Depending on the firmware version, the location of some menu items may vary slightly, but the general logic remains the same. If you are faced with a situation where night mode is turned on spontaneously or does not turn off through standard settings, here you will find a solution.

1. Disconnect night mode through the basic settings

The most obvious way is to use the standard settings menu, which is suitable for most users who want to completely deactivate the feature or temporarily suspend it.

Go to Settings → Screen → Night mode. Here you will see three key parameters:

• 🌙 Turn on/off: Main switch of the function. Move the slider to the left for complete shutdown.
• ⏰ Schedule – If the mode is turned on by time, select “No” or edit the interval.
• 🔄 Automatic low light switching on – turn off this item if the screen turns yellow in dark rooms.

Once all options are disabled, the Redmi 9 NFC night mode will stop activating until the next device restart or manually activated, but in some versions of MIUI, settings may be reset after the system update.

2. Quick shutdown via notification panel

If you need to temporarily remove the yellowness of the screen, without digging into the settings, use the Quick Access Panel:

1. Swipe your finger down to open the notification curtain.
2. Find the "Night Mode" icon (usually depicted as a crescent with stars).
3. Slap it once to turn it off. If it's not there, click on "Edit" and add it to the active elements.

This method only works until the next automatic turn on schedule, and to fix the result, you have to go to the settings, as described in the first section.

💡

If the night mode icon has disappeared from the notification panel, try rebooting your smartphone – sometimes this brings back hidden elements.

3. Reset screen settings (if the mode is not turned off)

In rare cases, night mode may "hang" in the active state due to a failure in the MIUI. This manifests as a constant yellowness of the screen, which cannot be removed by standard methods.

Go to Settings → System → Reset → Reset screen settings. Confirm action. This method does not affect personal data, but will return to factory values:

• 🎨 Brightness and contrast
• 🔄 Automatic lighting adjustment
• 🌓 Night mode settings

After reset, check the screen, and if the problem persists, it could be a damaged firmware or a hardware failure of the matrix.

4. Set up exceptions for individual applications

MIUI allows you to create whitelists of applications for which night mode is turned off automatically, which is convenient if you only need natural color reproduction in certain programs (for example, in graphics editors or games).

Algorithm of action:

1. Open Settings → Screen → Night mode → Exceptions.
2. Tap "Add Apps" and select the ones you need from the list.
3. Save the changes.

Note that exceptions only work when the night mode is active, and if it's completely off, the exception settings have no effect.

5.Using Developer Mode for Fine-Tunes

For power users who want to have full control of night mode, hidden settings are available through developer mode.

Go to Settings → About Phone → MIUI version and tap this item 7 times in a row. After the notification “You became a developer” appears, return to the main settings menu, where a new section will appear Additional → For developers.

Inside, find the parameters:

• 🔧 Turn off automatic color correction – blocks all automatic color temperature changes.
• 📱 Simulation of color space – allows you to manually specify a color profile (select “Disabled").
• 🔄 Night mode debugging – shows technical information about current filter settings.

Activate Developer Mode (7 taps according to MIUI)

Find the section "For developers" in the settings

Turn off "Automatic Color Correction"

Reset the device to apply changes-->

Be careful: Incorrect settings in developer mode can lead to incorrect screen operation or other system functions.

6 Problems and Solutions: Why Night Mode Doesn't Turn Off

If none of the methods described have worked, the reasons may be as follows:

⚠️ Note: On some firmware from third-party developers (for example, Xiaomi.eu or custom builds), the night mode can be hard sewn into the system. MIUI.

Common problems and their solutions:

• 🔄 The mode is turned on itself after restarting → Check for updates MIUI or reset the screen settings.
• 📱 No "Night mode" in the settings → Maybe your firmware has been modified. Try to find the settings by searching the settings menu (the magnifying glass icon at the top).
• 🔧 The screen remains yellow even after shutting down. → This could be a hardware problem with the matrix or the display plume.

To diagnose hardware problems, try loading your phone into Safe Mode (hold the power button → long tap on "Stop" → "Reboot in Safe Mode"). If the screen displays colors normally in Safe Mode, the software problem is.

7. Alternative methods: applications for screen color control

If standard methods don’t work, you can use third-party utilities from Google Play, which offer more flexible color temperature and schedule settings:

Third-party applications have the advantage of being able to accurately calibrate color temperature (e.g. setting a 4500K value instead of the standard 2700K in MIUI), but they require additional permissions and may conflict with system settings.

⚠️ Note: Some antivirus programs (such as Avast or 360 Security) have built-in vision protection modules that can duplicate night mode.
