Why Xiaomi is darkening wallpaper: 7 reasons and how to fix it

Have you noticed that your Xiaomi smartphone has a dull desktop wallpaper, as if covered with a gray veil? Or bright colors suddenly turned into faded shades and the black background became grayish? This problem is common for many users of devices based on MIUI — from budget Redmi to flagship Xiaomi 13/14. In most cases, the darkening of the wallpaper is not due to a breakage of the screen, but is the result of software algorithms or incorrect settings.

In this article, we’ll take a closer look at 7 main reasons why Xiaomi wallpapers can dim, from adaptive brightness and energy-saving modes to firmware bugs and thematic conflicts. You’ll also find step-by-step instructions for diagnosing and fixing the problem, including hidden MIUI settings that are rarely mentioned in official documentation. If you’ve tried rebooting your phone or changing wallpaper without result, here’s what to do next.

1. Adaptive brightness and automatic color correction

The most common reason Xiaomi has darkened wallpaper is its Adaptive Brightness function, which not only adjusts the screen’s backlight to depend on the lighting, but also automatically adjusts the color gamut to reduce eye strain, making bright wallpapers appear muted, especially in dark rooms.

In addition, MIUI 12-14 adds Reading Mode 2.0, which filters blue light while reducing color saturation, and if activated, the wallpaper will appear dim even at maximum brightness.

• 🔦 How to check: Open the notification curtain – if the Read Mode icon is highlighted, the function is active.
• 🌡️ Test: Turn off adaptive brightness in Settings → Display. → Adaptive brightness and compare wallpaper colors.
• 🎨 In some models (for example, Xiaomi 12 Pro) there is a hidden setting Color profile – it can be found through a search in the settings.

⚠️ Warning: If the wallpaper is still dim after the adaptive brightness is turned off, the problem may be with screen calibration. In this case, try resetting the display settings to factory settings (Settings) → Display. → Resetting display settings).

2. Energy saving regimes and limitations of MIUI

MIUI aggressively optimizes power consumption, especially on devices with weak processors (such as Redmi 9A or Poco M3). In Battery or Super Power Saving modes, the system not only limits the background activity of applications, but also reduces the color depth of the screen to reduce charge consumption.

Another hidden feature is Background Color Limit, which activates automatically when the battery is below 15%, and reduces saturation of all interface elements, including wallpaper.

To check if energy saving is affecting your wallpaper, follow the following steps:

Turn off all battery modes in Settings → Battery

Charge your phone to 100% and check the wallpaper

Restart the device (sometimes resetting the MIUI cache helps)

Try to install static wallpaper instead of dynamic-->

3. Conflict of design and wallpaper topics

MIUI Themes often causes visual glitches, including wallpaper dimming, because some themes (such as "Dark Universe" or "AMOLED Black") put additional filters on the desktop, even if you manually installed light wallpaper, and problems arise when using dynamic wallpapers (such as Earth & Moon or Quantum Dot), which can conflict with the display settings.

Another nuance: if you downloaded wallpapers from GetApps or third-party sources, they may contain built-in transparency or dimming options that MIUI misinterprets, especially for.apk wallpapers (like Google Wallpapers’ live wallpapers).

• 🖼️ Solution 1: Install standard wallpaper from Xiaomi Gallery and check if the problem persists.
• 🌑 Decision 2: Turn off the subject in Settings → Topics → My subjects. → No subject.
• 🔄 Solution 3: For dynamic wallpaper, try resetting their settings: Long-press on desktop → Wallpaper settings → Reset.

💡

If the wallpaper only darkens on the home screen but stays bright in the app menu, the problem is precisely related to the theme or launcher.Try installing an alternative launcher (like Nova Launcher) to check.

4. firmware bugs and MIUI errors

Some versions MIUI They contain errors that lead to improper processing of flowers. MIUI 13.0.4–13.0.6 was a bug that caused the wallpaper to turn grey after the update. MIUI 14 A similar problem occurred when using the Super Wallpapers function on devices with AMOLED-screen.

If the wallpaper darkened after the firmware update, it's probably the software's fault.

1. Clean the system cache (Settings → Memory → Clear the cache).
2. Reset the launcher settings (Settings → Applications → Application Management → Launcher → Storage → Clear data).
3. Reverse to the previous version of MIUI (if available).

⚠️ Warning: Before you cache or roll back the firmware, back up your data. In some cases, cleaning the cache may cause widgets to fail or delete saved themes.

If the problem has occurred after a beta update, check out reviews on forums (such as XDA Developers or 4PDA). Often users share temporary solutions, such as installing a patch through ADB:

adb shell settings put global force_dark 0


adb shell settings put global dark_theme 0

5. Hardware problems: matrix or screen plume

If the software methods didn't work, the reason for the wallpaper darkening could be a hardware malfunction, most often the fault is:

• 📱 Damage to the display plume (for example, after falling or disassembling the phone) This leads to uneven dimming or color spots.
• 🔋 Wearing of the matrix (relevant to older models, such as the Redmi Note 5 or Mi 8). AMOLED-screens lose brightness, especially in the area of static elements (for example, navigation panels).
• 🌡️ Overheating: If the phone gets hot, the display controller can automatically dim the brightness to protect the matrix.

To diagnose a hardware problem:

1. Look at the screen from different angles – if the blackout is uneven (for example, stronger in one corner), it is a sign of damage to the plume.
2. Run the display test via the engineering menu: ##6484## or use the Screen Test app from Google Play.
3. Check if the problem persists in Safe Mode. If the wallpaper is darkened there, the iron is to blame.

6.The Impact of Third-Party Applications

Some apps can interfere with displaying wallpaper even if you don't notice it.Typical offenders:

• 🔳 Battery saving apps (e.g. Greenify, AccuBattery) – they can force the screen to lower brightness.
• 🎨 Launchers and widgets (e.g. Nova Launcher, KWGT) — Some of them put their filters on the desktop.
• 👁️ Vision protection applications (e.g. f.lux, Night Shift) – they change color temperature, which can affect wallpaper.

To find the culprit:

1. Launch your phone in Safe Mode (see spoiler above). If the wallpaper is normal, the problem is with third-party software.
2. Turn off applications that have access to the display settings (Settings → Applications → Permissions → Change system settings).
3. Check the settings of the applications for battery saving – some of them block wallpaper updates.

💡

If wallpaper blackout appears after installing a new app, first check its settings. For example, Nova Launcher has a Screen Filter option that can mute colors.

7. Features AMOLED-screening and color calibration

Xiaomi devices with AMOLED-screens (for example, Xiaomi 13 Ultra, Redmi) K60 Pro) have unique calibration settings that may affect the display of wallpaper:

• 🔴 DC Dimming (PWM) – technology that reduces screen flickering, but sometimes leads to color fading.
• 🎛️ Color profile - in MIUI There are hidden profiles (Saturated, Natural, sRGB) that change the gamut.
• 🖥️ Adaptive color – a function that automatically adjusts colors to lighting (may conflict with wallpaper).

To set the display to AMOLED-screen:

1. Open Settings → Display → Color Mode and select Saturated (for bright wallpaper) or sRGB (for natural colors).
2. Turn off DC Dimming in Settings → Display → Flicker Mode (if enabled).
3. For accurate calibration, use the Screen Balance app (available on Google Play).

⚠️ Note: Some models (e.g. Xiaomi) 12T) Changing the color profile requires rebooting the phone. Also remember that saturated mode increases battery consumption by 5-10%.
