Xiaomi Poco X3 is one of the most popular smartphones in the budget segment, but its night mode feature (or "Eye Comfort Mode") often raises questions from users. Some face the fact that the screen turns yellow for no apparent reason, others can not find where to turn this setting off, and still others face a bug when the mode turns on on itself.
It's important to understand that the night mode on the Poco X3 can work in two ways: as an automatic blue light filter (on schedule) and as a manual fixed temperature setting. Also, on some MIUI firmware, this feature is duplicated in different menu sections, which creates confusion, and we'll look at both scenarios and give solutions for each situation.
If you've tried to turn off mode through standard settings, but you can't, don't rush to drop your phone, and maybe the problem is developer settings, application conflict, or even a hardware failure of the light sensor, and more on that and more.
1. Standard shutdown via screen settings
The most obvious way is to use the main settings menu. On the Poco X3, the path to night mode may differ depending on the version of MIUI (12, 13 or 14), but the general logic is maintained.
- Open the Settings app** (cog icon).
- Go to the Display section (or the Screen in some firmware).
- Find Read Mode or Eye Comfort (may be called Night Mode or Blue Light Filter).
- Move the slider to the "Off" position or uncheck the checkmark from the automatic turn on.
If you don’t have Eye Comfort on your menu, try an alternative route:
- 🔍 Settings → Additionally. → Special facilities → Color proofreader (sometimes night mode is hidden here).
- 🔍 Settings → Battery and productivity → Battery mode → Night mode (in older versions) MIUI).
⚠️ Note: On some Poco firmware X3 After the night mode is turned off, the screen may remain yellowish, due to hardware calibration of the matrix. To reset the color rendering, restart the phone or activate Standard mode in the color settings (Settings) → Display. → Color scheme).
2. Disconnect via the notification panel (quick settings)
A quick way to turn off night mode is to use the notification curtain, but on the Poco X3, this feature can be hidden or replaced with another icon.
- Swipe your finger down to open the notification panel.
- If there is no Eye Comfort icon, swipe down again to turn the full panel around.
- Find an icon with an eye or crescent image (may be called Night Mode or Blue Filter).
- Tap the icon once to turn off the mode.
If the icon is not in the curtain:
- 🔧 Click on “Edit”** (pencil icon) in the notification bar.
- 🔧 Find it in the Eye Comfort list and drag it to the active area.
- 🔧 Save the changes and try to turn off the mode again.
On some MIUI 13+ firmware, the Night Mode icon can be replaced with Dark Theme, and don’t confuse these features: Dark Theme changes the interface design, and Night Mode changes the color temperature of the screen.
☑️ Check before turning off night mode
3. Automatic turn on schedule: how to remove
A common problem is that the night mode turns on itself at a certain time, and this is due to an automatic schedule that you can turn off.
- Go to Settings → Display → Eye Comfort.
- Click on “Schedule”** (or “Automatic Turn on”).
On some versions of MIUI, the schedule can be geolocated (turned on at sunset) to fix this:
- 🌍 Open the Settings. → Confidentiality → Permits → geodata.
- 🌍 Find the Eye Comfort list and disable location access.
| MIUI version | The way to the schedule | Features |
|---|---|---|
| MIUI 12 | Settings → Display → Reading Mode → Schedule | It can be called "Read Mode" instead of "Eye Comfort". |
| MIUI 13 | Settings → Display → Eye Comfort → Automatically | There is a sunset/dawn reference. |
| MIUI 14 | Settings → Screen → Color Temperature → Schedule | Added filter intensity setting |
⚠️ Warning: If night mode is still turned on after the schedule is turned off, check out third-party apps that can control color temperature (such as Twilight, Night Shift or Blue Light Filter.
4. Reset screen settings to factory
If the night mode is not turned off by any means, the system settings of the screen may have gone wrong, in which case the reset will help:
- Open the Settings. → The phone.
- Find the item “Resetting”** (or “Recovery and Reset”).
This method will return all display parameters to factory ones, including:
- 🎨 Color temperature
- 🔄 Display modes (Standard, Saturated)
- 🌙 Night mode settings and blue light filter
If you do not have the option to “Reset Screen Settings”**, use a partial reset:
- Go to Settings → Applications → Application Management.
- Find the “Settings”** (cog icon) and open it.
- Click on “Storage”** → “Clear Data”.
What if the reset didn't help?
5. Disconnection through the developer settings
In rare cases, night mode is controlled by hidden parameters that can only be changed through the developer mode.
- Activate Developer Mode: Go to Settings → About the phone. Press 7 times on "Version." MIUI»** (A notification will appear saying, “You have become a developer!»).
«Additionally. → For developers»
«Night Display»
"Disconnected."
If there are no items in the developer menu, try an alternative method using ADB:
adb shell settings put global night_display_available_for_user 0
adb shell settings put global night_display_activated 0These commands will completely disable the night mode at the system level, but they will require:
- 🖥️ Computer with installed ADB-driver
- 🔌 Included debugging by USB phone-on
- 📱 Poco connection X3 PC in the mode "File transfer»**
💡
If, after use, ADB-commands night mode is back on, check if settings are reset after rebooting. /data — In this case, only re-flashing will help.
Problems and Mistakes: What to Do When Nothing Works
If you’ve tried all the ways, but the night mode on the Poco X3 is still active, the reason could be one of the following:
| Problem. | Possible cause | Decision |
|---|---|---|
| The mode turns on itself | Illumination sensor failure | Turn off automatic brightness adjustment or replace the sensor |
| Settings are not saved | Damage to MIUI files | Check your phone with the Mi Flash Tool. |
| The screen remains yellow even after shutting down. | Hardware calibration of the matrix | Use Screen Balance app to manually set up |
One of the most difficult cases is when night mode is turned on due to firmware damage after a failed update.
- Download the official firmware for Poco X3 from the Xiaomi website.
- Use the Mi Flash Tool for clean installation (select the Clean All option).
- After the firmware, reset the settings (Wipe Data in Recovery).
If the phone is warranty, don’t flash it yourself, contact Xiaomi’s service center with a description of the problem. Please indicate that the night mode is not turned off either through settings or through reset.
💡
If night mode is activated due to the light sensor, temporarily turn off automatic brightness control in Settings → Display → Automatic brightness. This will help diagnose a hardware malfunction.
