Many users experience a situation where the screen of Xiaomi smartphone suddenly turns yellow or becomes too dark in the evening. This is not a break in the display, but the system functions of vision protection that are activated automatically on a schedule. Often device owners forget about the settings turned on or do not know where to look for switches in the new version of the MIUI shell or HyperOS.
In this article, we will explore all the possible causes of color reproduction and brightness changes, learn how to control reading modes, dark themes and automatic adjustment, which will help restore the usual white balance and comfort when using the gadget at any time of the day.
Before you start settings, it’s important to understand the difference between night mode, which reduces the blue spectrum, and dark theme, which changes the color of the interface, which are often confused, but they are turned off in different sections of the menu, and correctly identifying the problem will save you time and nerves.
Disabling reading and vision protection
The most common reason for a yellow screen is the activated Read Mode function, which is designed to reduce eye strain by mimicking the colors of a paper book, and in newer firmware versions, this setting can be activated automatically when certain applications are launched or by time of day.
To eliminate this effect, you need to go to the basic settings of the system, find the partition responsible for the display, and carefully study the points related to color and vision protection, usually there is a slider that puts the screen in monochrome or warm mode.
Notice the Vision Protection tab, where you can activate Read Mode 3.0 or the classic blue filter, and if the slider is blue, it's working, put it inactive to restore normal color reproduction.
⚠️ Attention: Long-term use of reading mode during the day can distort the perception of colors in photos and videos, so it is recommended to turn it on only when reading the text for a long time.
There is also the option of fine-tuning the color temperature. If the screen still seems too warm after turning off the main filters, check the color scheme settings. Select Standard or Saturated mode to remove the excessive yellowness characteristic of eye protection mode.
Managing the dark theme of the interface
Another reason for the night view of the smartphone may be the Dark Theme, which, unlike the blue light filter, changes the background of apps and system menus to black or dark gray. AMOLED-screens, but not suitable for all use.
To turn off this feature in the MIUI or HyperOS shell, you need to go to the Settings app. Next, go to the Screen path and find Dark Theme. In some firmware versions, this switch is placed in the top notification curtain for quick access.
It is important to distinguish between system dark theme and dark themes in specific applications. For example, YouTube or Telegram may have their own design settings that do not depend on the overall settings of the phone.
- 🌓 Open the notification curtain and look for the “Moon” or “Theme” icon».
- 🌓 Go to the screen settings and turn off the “Dark Theme” switch».
- 🌓 Check the settings of individual applications, such as browser or instant messengers.
- 🌓 Make sure that automatic time switching is not activated.
If you use third-party launchers or themes from MIUI Themes, they may be forced to include dark design, in which case you need to change the theme to the standard or disable the use of dark elements in the settings of the theme itself.
☑️ Checking screen settings
Scheduling and automation
Often users can't understand why the modes are turned on by themselves. The answer lies in the Automatic Turn on feature, which allows you to set time intervals, for example, from 22:00 to 07:00, when vision protection or a dark theme will be activated without human intervention.
To remove the night mode that is turned on by the timer, you need to find the appropriate item in the display settings menu, usually called "Schedule" or "Switch on automatically," inside this menu you can turn off the timer completely or adjust your hours of operation.
It's also worth checking the Digital Well-Being section, which can have a "Sleep" or a "Do Not Disturb" mode set up, which indirectly influences screen behavior. Although they don't change colors directly, they often come bundled with a darkening interface.
| Function | Where to find out. | Screen impact |
|---|---|---|
| Reading mode | Settings → Screen → Protection of vision | Makes the screen yellow or black and white |
| Dark subject matter | Settings → Screen → Dark Theme | Makes the interface background black |
| Autobrightness | Settings → Screen → Brightness Level | Changes brightness on the light sensor |
| Sleep regimen | Digital well-being | May include a monochrome regimen |
Be sure to check the alarm settings. Some Xiaomi models suggest turning on the “Do Not Disturb” mode at night when setting the alarm, which can also change the visual style of the screen lock and interface.
Specifics of models with AMOLED and E Ink
Owners of Xiaomi flagship models, such as the Mi 11 series, Xiaomi 13 or Redmi Note with AMOLED-matrixes, face the peculiarities of the pixels. On such screens, black is achieved by completely turning off the backlight, which makes a dark theme especially effective, but sometimes excessive.
Remove the night mode on AMOLED-You can use special engineering menus or additional display settings, but be careful: changing some parameters in the engineering menu can lead to incorrect display of colors in all applications.
For devices with E Ink screens, such as Xiaomi e-books, the concept of night mode is radically different, where color inversion (white text on a black background) is the main way to reduce eye strain in the dark, and it is turned off by switching the contrast button on the case or in the book menu.
⚠️ Attention: AMOLED-On screens, the constant use of maximum brightness in the dark can lead to pixel burnout, so it is not recommended to completely abandon autobrightness.
If you have a 120Hz refresh rate model, make sure that the nighttime power saving mode is not activated, which forcibly reduces the frequency to 60Hz and changes the color range to save battery power.
Why does the screen turn yellow after the update?
Third-party applications and conflicts
Sometimes the built-in settings have nothing to do with it, and the culprit of the yellow screen is a third-party application. Book readers, night browsers or blue light filters from Google Play can block system settings.
Check the list of newly installed applications. If you downloaded an eye protection program, it can run in the background, overlaying a translucent filter over the entire interface, uninstall such applications or disable their display permissions over other windows.
Screen recording or streaming apps, which may include their own overlays, may also conflict, disable suspicious programs one at a time to identify the culprit behind the color change.
- 📱 Check the running apps in the background.
- 📱 Turn off permissions to “overlay over other windows».
- 📱 Remove third-party blue light filters.
- 📱 Restart the device in Safe Mode to check.
Special attention should be paid to launchers. If you have installed a third-party shell, it may have its own themes and night mode settings that ignore Xiaomi system settings.
Resetting settings and additional methods
If none of these things worked, there may have been a software failure in the display drivers, which may require a deeper intervention. Start by simply restarting the device, as this often clears the temporary caches responsible for display.
There's a hidden engineering code that allows you to check the display, type ##6484## into the phone to log into the engineering menu, and you can run screen tests there, but be careful not to change the parameters that you don't know what they mean.
In extreme cases, if the problem is caused by a bug in the system after a failed update, resetting all settings to factory can help.This action will delete all your data, so be sure to back up contacts and photos before the procedure.
💡
Before resetting, try simply restarting your phone in Safe Mode, and press the off button until you have a suggestion to go to Safe Mode to help you see if the third-party app is to blame.
Once the settings are reset, the phone will return to factory status, where the default night mode is turned off, guaranteed to solve the problem if it is not due to physical damage to the matrix or the display plume.
💡
In 90% of cases, the problem is solved by turning off Read Mode or Vision Protection in the main screen settings, without the need for complex manipulations.
