Xiaomi Poco X3 is one of the most popular smartphones in the budget segment, but its night mode (or “Read Mode”) function does not always work as you would like. Many users are faced with the fact that the screen suddenly turns yellow, contrast drops, and colors become unusually warm. This is not a breakdown, but a feature of MIUI, Xiaomi’s proprietary shell. In some cases, the night mode is automatically turned on on on schedule, in others – activated accidentally through the notification panel.
In this article, we’ll look at all the ways you can turn off the night on the Poco X3, including hidden settings and commands for power users, how to remove the yellowness of the screen once and for all, why the mode can turn on on on itself, and what to do if standard methods don’t work, and also give tips on how to adjust color reproduction to make the screen look natural at any time of the day.
What is Xiaomi Night Mode and Why You Need It
Night mode (or Night Mode) is a feature that reduces the amount of blue light emitted by the screen, which in theory should reduce eye strain when using a smartphone for long periods of time in the dark. X3 It is implemented through two mechanisms:
- 🌙 Read mode – a filter that makes the screen yellowish, simulating the warm lighting of the lamp.
- 🌃 Dark theme – don’t confuse it with night mode! is a separate feature that changes the background color in system applications from white to black.
By default, MIUI can automatically turn on night mode from 22:00 to 07:00, but this time can be changed or turned off completely. However, many users complain that even after manually switching off, the mode is activated again.
- ⏰ Automatic schedule in settings.
- 📱 Accidental click on the icon in the notification panel.
- 🔄 Resetting settings after update MIUI.
- 🤖 Third-party application influences (e.g. Twilight or f.lux).
Method 1: Disconnect via screen settings
The most obvious and safe method is to turn off the night mode in the settings menu. On the Poco X3, the path may vary slightly depending on the version of MIUI, but the general scheme is as follows:
- Open Settings (the gear icon on the main screen).
- Go to the Screen section.
- Slip on the item Read Mode (or Night Mode in some firmware).
- Move the slider to the off position.
If you have an automatic schedule, you also need to deactivate it:
- 🕒 In the same menu, find the Schedule option.
- 🔘 Turn off the switch automatically.
- 🗓️ If there are custom time frames (for example, from 21:00 to 06:00), reset them.
Slider in the section "Reading mode" in the position "Off."|

The screen colors are back to standard.-->
Important: Some versions of MIUI may still have a slight yellowish hue after the night mode is turned off, and this is due to color profile settings, as we will discuss in one of the following sections.
Method 2: Quickly shut down via notification panel
If the night mode is switched on by accident, you can turn it off in a few seconds through the notification curtain.
- Swipe your finger down to open the notification panel.
- Find the Night Mode icon (usually a crescent icon) 🌙).
- Slap it once, the mode will go off.
If the icons are not in the main panel:
- 🔍 Flick the curtain to the left to see all the available switches.
- ⚙️ Click on the pencil icon (Edit) to add Night Mode to the main menu.
💡
If the nighttime gray icon is inactive, it's already off. In some firmware, the icon may look like a book (📖) — It's the same "Reading Mode".
This is a convenient way to quickly return the normal colors of the screen, but does not solve the problem of automatic activation. If the mode activates on its own, you will have to dig deeper - read the next section.
Method 3: Disconnect via ADB (for power users)
If standard methods do not help, and the night mode is persistently turned on itself, you can use the ADB-It's an advanced method that requires you to connect your smartphone to your computer, but it's guaranteed to work even on custom firmware.
You'll need:
- 🖥️ A computer with installed Xiaomi drivers and ADB Tools.
- 📱 Included Debugging by USB on a smartphone (in Settings) → The phone. → Version. MIUI, Tap 7 times, then return to the Additional Settings → For developers).
- 🔌 USB-cable (preferably original).
Instructions:
adb shell settings put global night_display_auto_mode 0
adb shell settings put global night_display_activated 0These teams:
- 🔘 Turn off the automatic schedule (night_display_auto_mode 0).
- 🔘 Turn off the night mode itself (night_display_activated 0).
What if the ADB does not recognize the device?
After you execute the commands, restart your smartphone. Night mode should disappear forever, unless you turn it on manually.
💡
ADB-The teams reset the system-level night-mode settings, and that's the only way to turn it off completely if you're not in the system. MIUI ignores manual settings.
Why does the night routine turn on on on its own?
If you have already turned off night mode, but it continues to activate, the reasons may be as follows:
| Reason. | How to check | Decision |
|---|---|---|
| Automatic schedule | Go to Settings → Screen → Reading Mode → Schedule | Turn off the option automatically |
| Third-party annexes | Check out the permissions for Twilight, f.lux, Blue Light Filter | Remove or disable the rights to overlay |
| MIUI Update | After the update, the settings were dropped | Re-engineer the manual mode |
| Battery optimization | In Settings → Battery → Battery Optimization Check System Applications | Disable optimization for MIUI System Interface |
The problem is especially common after MIUI updates. For example, the Poco X3 versions of MIUI 12.5 and MIUI 13 had a bug that caused the night mode to turn on when the battery was low.
- 🔋 Disable Ultraeconomic mode in battery settings.
- 🔄 Reset the Screen application settings (Settings) → Annexes → Application management → Screen. → Warehouse → Reset).
💡
If the problem has occurred after the update, check the XDA Developers or 4PDA forums, which often provide patches for such bugs.
How to adjust the screen colors after turning off the night mode
After the night mode is deactivated, the screen may look too cold or unnatural, because MIUI uses aggressive color profiles by default to return the natural color reproduction:
- Go to Settings → Screen → Color mode.
- Select Standard (or sRGB if available).
- Turn off the option of Automatic Color Customization.
If you don’t like the standard profile, you can manually calibrate the screen:
- 🎨 In the same menu, select Color Settings.
- 🔴 Adjust the Red, Green and Blue sliders to comfortable values.
- 🌡️ For accurate calibration, use test images (e.g., a gray scale).
Professional advice: If you work with photos or videos frequently, set up a DCIP3 profile – it provides a wider color coverage, but can slightly distort shades in everyday use.
What to do if nothing helps
If you have tried all the ways, but the night mode is still turned on, there are radical measures:
- Resetting screen settings: 📱 Go to Settings. → Annexes → Application management. 🔍 Find the Screen app. 🗑️ Press Warehouse. → Reset.
Rejection of the MIUI update:
If the problem has appeared after the update, you can return to the previous version of the firmware via Fastboot, 4PDA).
Installation of custom firmware:
Firmware like Pixel Experience or LineageOS doesn’t have Xiaomi’s built-in night mode, but will require unlocking the bootloader.
💡
Before you reset or flash backup your data! Use Mi Cloud or TWRP for backup.
If you are not sure about your abilities, it is better to contact the Xiaomi service center, in some cases the problem may be related to a hardware failure (for example, a malfunction of the light sensor).
