Modern. OLED-Smartphone screens not only allow you to enjoy juicy color reproduction, but also significantly save battery power when using a black interface. Owners of Xiaomi, Redmi and Poco devices often look for a way to activate this mode to reduce the load on the eyes at night. MIUI HyperOS provides flexible tools to personalize the appearance of the shell.
However, standard night mode inclusion does not always color all interface elements in the desired black. Many system applications and third-party programs remain white, which creates imbalance and reduces the effectiveness of dimming. In this article, we will discuss hidden settings, forced activation methods and the nuances of Dark Mode on different versions of firmware.
You will learn how to get system applications to ignore a bright developer theme and what the limitations of this feature are. We will look at both the standard tools and advanced methods for experienced users who want to achieve the perfect black background in all corners of the operating system.
Standard activation through system settings
The basic way to switch the interface is available to every user without having to obtain superuser rights or install third-party software. You just have to open the main settings menu of your Xiaomi smartphone. Find the Screen or Wallpaper and personalization section where the theme switch is located.
Once a dark theme is activated, the system will automatically repaint the desktop background, notification curtain and standard apps black, which helps reduce the load on the screen matrix, especially if you have a model with AMOLED technology, and on such displays, the black pixel simply turns off, which really saves energy.
In some versions of the shell, the path to customization may vary slightly depending on the firmware region (Global, EU, China).If you do not find the switch in the screen section, try searching for it through a global search by settings by typing in the "Theme" query.
- 🌑 Open Settings and go to the Screen section.
- 🌓 Select the Topic and activate the Dark Theme switch.
- ⚙️ For fine tuning, press the gear next to the switch.
- 📱 Check the display in standard applications: Contacts, Phone, Gallery.
⚠️ Warning: Including a dark theme can change the look of some third-party apps if their developers have not provided responsive design.
It's worth noting that not all interface elements change instantly. Some system dialogs require rebooting the device or re-entering the application to apply new styles. This is normal behavior by the Android operating system in conjunction with the manufacturer's shell.
Forced Enablement for All Applications
Standard mode often leaves many applications white because they don’t have built-in support for dark theme. To fix this, MIUI and HyperOS have a special forced dimming feature that forces the system to ignore the app developer’s preferences and impose a black background.
To activate this feature, you need to go to the advanced theme settings, and here you will see a list of all the programs installed, you can choose a specific application or use a button to cover all the programs on the device at once.
Some applications with complex interfaces may display incorrectly: text can merge with the background, and icons can become invisible, so it is recommended to check each application individually.
☑️ Verification of the coercive regime
It's important to understand the difference between the system theme and the theme of a particular application. If you've enabled forced dimming but Telegram or WhatsApp is still light, check their internal settings.
- 🔧 In the theme menu, click on the settings gear.
- 📲 Select the item Separate Appendices or Forced.
- ✅ Activate the switchboard Enable for all applications.
- 🔄 Restart modified programs to apply settings.
⚠️ Warning: Forced dimming can cause increased battery consumption in apps with a lot of animations, as the processor will have to recalculate colors on the fly.
Planner setting and automation
Manually switching the theme every time the sun sets is inconvenient. Xiaomi's system offers a built-in scheduler that automatically changes the design at a given time. It's not only convenient, it's also good for eye health.
In the theme settings, you will find the Schedule option, where you can select the sunrise and sunset switching on using the device's geolocation. Alternatively, you can set fixed hours, such as 21:00 to 07:00.
Automation works steadily even after a smartphone reboot, but it is worth considering that the sun mode requires access to geo-position and the Internet to accurately determine the time of astronomical events in your region.
| Parameter | Description | Recommendation |
|---|---|---|
| Sunrise/Sunset | Automatically over GPS. | The Best Option for Eye Health |
| Predicted time | Fixed clock | For a stable day regime |
| Disconnected. | Manual control | For advanced users |
| Brightness | Decrease in inclusion | Recommended activation |
You can also adjust the brightness behavior of the screen when you switch to dark mode, and often the system itself suggests reducing the brightness to make it more comfortable to perceive black backgrounds in low light conditions.
Use of dark topics in the app Topics
The Themes' built-in app is a powerful tool that goes far beyond simply changing the background color. The Theme Store offers thousands of designs that completely change the look of icons, curtains, settings menus and system windows.
To find a quality dark topic, search for the keywords: “Black”, “Dark», «AMOLED». The theme description often states whether it supports deep black, which is important to owners. OLED-screen.
How to install a theme for free?
When installing a new theme, pay attention to compatibility with your version of Android and MIUI. Outdated themes may not display correctly on new smartphones, causing graphical glitches.
- 🎨 Open the Topics app on the desktop.
- 🔍 Type “Dark” or “Black” into search».
- 👁️ Use preview to evaluate the appearance of icons.
- ⬇️ Download and apply your favorite theme, confirming the action.
Remember that using a third-party theme can temporarily change the way system fonts work. If you notice a problem with readability after installing the theme, go back to standard design through the user profile.
Hidden opportunities through the engineering menu
For users who lack standard options, there is access to hidden features through special codes. USSD-#86569726## (or similar for your model) opens the hidden theme debugging menu.
In this menu, you can find a Force Dark Mode switch that runs at a deeper level than a normal setting, and it forcibly redraws the interface, ignoring many of the limitations, and be careful that changing these settings can lead to unstable system operation.
Using the engineering menu doesn't require Root rights, but it requires care. Don't change the values of the parameters you're not sure about. Back up the data before you experiment.
⚠️ Note: Signing into the engineering menu and changing hidden settings is at your own risk.The factory warranty may not be extended to software failures caused by interference with system files.
💡
Before entering the engineering menu, take a screenshot of the current parameters values so that in case of problems, everything can be returned as it was.
If the interface is unreadable after the changes, try restarting the device in safe mode, which will disable all third-party modifications and return access to the settings.
Solutions and Display Problems
Often users are faced with a situation where a dark theme is enabled, but some elements remain white.This may be due to app cache or version conflict.Try clearing the cache of the problematic app through settings.
Another common problem is color inversion in photos or videos, which occurs when the system mistakenly applies an inversion to content that already has color profiles, and in such cases, adding an app to exceptions helps.
If a dark theme spontaneously turns off, check the energy saving settings. Aggressive battery optimization can kill the process responsible for switching interface styles.
- 🧹 Clear the app cache Themes and System UI.
- 🚫 Add problematic apps to dark topic exceptions.
- 🔋 Turn off ultra-energy saving to check stability.
- 📲 Make sure the app is updated to the latest version.
💡
Most display problems are solved by cleaning the system interface cache or updating the problem application to the current version.
In rare cases, a bug in a particular firmware version may be the cause.See system updates as Xiaomi engineers regularly release patches that correct visual errors.
