How to remove the night mode on Xiaomi Redmi 9: 4 working ways

Xiaomi Redmi 9 is one of the most popular budget smartphones with a shell MIUI, which offers a lot of useful features to protect vision. Among them is the night mode (or "Read Mode"), which automatically reduces the level of blue light for comfortable use of the gadget in the dark. However, not all users like the yellowish shade of the screen that this mode adds. If you are looking for how to return the natural colors of the display, this article will help you understand all the nuances.

We will look at not only the standard ways to turn off through Settings, but also alternative methods, such as through the notification panel or developer mode. We will focus on typical problems when the night mode does not turn off or turns on on itself. At the end, you will find answers to frequent questions and tips for adjusting color reproduction to your preferences.

What is Xiaomi Night Mode and Why You Need It

Night Mode (or Reading Mode) is a MIUI feature that filters blue light emitted by a smartphone screen. Studies show that blue light can disrupt the production of melatonin, a sleep hormone, which causes users to fall asleep longer after using gadgets before bedtime. Xiaomi Redmi 9 offers two options for this feature:

• 🌙 Night mode – reduces the brightness of the blue spectrum by adding a warm yellow hue.
• 📖 Read Mode – more aggressive filtering that mimics a paper book (not available on all versions) MIUI).

By default, mode can be activated automatically on a schedule (for example, from 22:00 to 7:00) or in low light (if the environment sensor is activated), but not all users like the change in color reproduction — especially those who work with graphics, watch videos or play games where color accuracy is important.

⚠️ Warning: Long-term use of a smartphone without nighttime exposure during the dark can cause visual fatigue and disrupt sleep cycles. If you turn off the feature, consider the alternatives of reducing screen brightness or using warm wallpaper.

Method 1: Disconnect via screen settings

The most obvious and universal method is to use the Settings menu, which works on all versions of MIUI (including MIUI 12/13/14) installed on Redmi 9.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Screen section.
3. Slip on Night Mode (or Read Mode, if available).
4. Move the slider to the off position. or uncheck next to the turn on.

If the night mode was set to schedule, additionally check:

• 🕒 Turn on/off time – turn off the automatic schedule.
• 🌓 Auto-adjustment – deactivate the option to Turn on automatically in low light.

After these actions, the screen should return natural colors. If the changes do not apply, try restarting the smartphone or using alternative methods below.

Method 2: Quickly shut down via notification panel

If you need to temporarily remove the yellowness of the screen without digging into the settings, use the notification panel, which is convenient when the night mode is turned on automatically, and you urgently need natural colors (for example, to view a photo or video).

Instructions:

1. Swipe your finger down the screen to open the notification bar.
2. Find the Night Mode icon (usually depicted as a crescent moon) 🌙). If it is not, tap on three dots or Edit inscriptions and add it to the panel.
3. Tap the icon once to turn off the mode.

⚠️ Attention: On some firmware MIUI The night mode icon may not be in the panel by default. In this case, add it manually via Edit → Night mode.

If the notification bar doesn’t respond to taps, try unlocking the screen or restarting the MIUI interface (hold the power button and select Reboot).

Method 3: Disconnect via Developer Mode (for power users)

In rare cases, night mode may not be turned off by standard methods due to MIUI failures or conflicts with other screen settings, and then the developer mode comes to the rescue, where you can force the function to deactivate.

Steps:

1. Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI until you become a developer!

This method should be used with caution, as it resets all screen overlays, including dark theme and other visuals. After turning off night mode, return the settings to their original state.

Method 4: Reset screen settings to factory

If the night mode continues to turn on on on its own even after manual shutdown, the problem may lie in the failure of the MIUI configuration files. In this case, resetting the screen settings will help - it will return all display parameters to factory values without affecting personal data.

How to reset:

1. Open the Settings → Screen.
2. Scroll down and select Reset Screen Settings (or Restore Default Settings).
3. Confirm the action by pressing OK.

💡

If night mode interferes with watching video, try using a gesture: double-touch the screen with two fingers to temporarily turn off the blue light filter (does not work on all versions of MIUI).

3 Colors remain yellow after shutdown

If the screen retains a yellow tint even after the night mode deactivation, the problem may be due to color profile settings or a graphics driver failure.

1. Go to Settings → Screen → Color Mode and select Standard.
2. Clear the Settings app cache through Settings → Apps → App Management → Settings → Storage → Clear the cache.
3. If nothing helps, do a soft reset (without data loss) through Settings → About Phone → Resetting.
