Wallpaper on Xiaomi suddenly darkened? 7 working ways to return brightness

You turned on a Xiaomi smartphone and found that the desktop wallpaper became unnaturally dark — as if it had been muted on purpose? — This problem occurs on devices with MIUI 12-14, and most often is not due to a screen breakdown, but to software settings or system bugs. In 80% of cases, you can fix dark wallpaper in 5-10 minutes without having to reset your phone.

The reasons for the wallpaper darkening range from the banal mode of energy saving to failures in the graphics driver. For example, after the MIUI update, many Redmi Note 11 and POCO X4 Pro users complained about the gray shade of background images. In this article, we will analyze all possible solutions from simple (brightness check) to advanced (resetting the GPU cache).

Before you panic, make sure the wallpaper isn't the problem. Try changing the background to the standard light version from the Xiaomi gallery. If the new wallpaper is displayed normally, it's the original file (it may be stored in the wrong color profile). If all the wallpaper is dark, regardless of the source, read on.

1. Check the basic brightness and contrast settings

Start with the obvious: it may have automatically lowered the brightness of the screen. There are several parameters in MIUI that can affect the display of wallpaper:

• 🌞 Adaptive Brightness: Turn it off in Settings → Display. → Adaptive brightness. Sometimes the light sensor will not work properly, obscure the screen.
• 🔋 Energy Saving Mode: Go to Settings → Battery. → Power saving mode and select "Switched off." In "Balanced" mode, the system can mute the colors.
• 🎨 Color profile: in Settings → Display. → Color mode, set "Standard" instead of "Sparing" or "Saturated"; the latter sometimes distorts the dark tones.

If the wallpaper is dark after this manipulation, move on to the next step. Note: on some models (for example, Xiaomi 12T) there is a separate item Contrast in the display menu - try to increase its value to 100%.

2.Reset wallpaper and themes settings

In MIUI, wallpaper and themes are controlled by a separate module, which sometimes crashes.

1. Open the Themes app (icon with brush).
2. Go to Wallpaper section. → My wallpaper.
3. Click on the three dots in the top right corner and select Reset Settings.
4. Confirm the action and restart the phone.

If there is no Reset option, try an alternative method:

• 📱 Remove current wallpaper through a long press on the desktop → Style. → Wallpaper. → Delete.
• 🔄 Install standard wallpaper from Xiaomi collection (for example, Horizon or Abstraction").
• 🔧 Reinstall the Themes app through Settings → Annexes → Application management → Topics → Remove updates.

💡

If the wallpaper is still dark after reset, check if a third-party theme is installed. Some themes from the Mi Theme Store artificially darken the background for "aesthetic effect."

3. Update or reinstall MIUI

Wallpaper darkening often occurs after a system update, especially if the firmware was installed with errors.

If you are not sure about your version of MIUI, check it in Settings → About Phone → MIUI Version. For stable wallpaper performance, a version at least MIUI 13.0.5 (for new models) or MIUI 12.5.7 (for devices 2020-2021) is recommended.

4. Check the developer settings

Sometimes dark wallpaper is the result of activating hidden parameters, like a simulation of color blindness or a forced dark mode, to turn them off:

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find and disconnect: 🔍 Simulation of color blindness (if included) 🌙 Forced dark mode (can affect wallpaper) 🎯 Debugging by USB (Sometimes conflicts with graphics settings)

Reboot the phone.

Also, check the hardware acceleration of visualization on the developer menu, and if it's turned off, turn it on. On some devices (like the POCO F4 GT), this solves the problem of wallpaper dimming.

💡

Turning on the developer mode doesn't void the warranty, but changing some parameters can lead to unstable system operation.

5.Reset the GPU cache

If the wallpaper is dark only on the desktop, and the gallery and apps have normal colors, the problem may lie in the cache of the graphics processing unit (GPU).

• 📱 Go to Settings. → Annexes → Application management.
• 🔍 Find the Lawnchair app (if any) or System interface MIUI.
• 🗑️ Press Warehouse. → Clear the cache.
• 🔄 Reboot the phone.

For a deeper cleaning, use the Recaveri menu:

1. Turn off the phone.


2. Press the Power + Volume buttons up until the Mi logo appears.




3. From the Recovery menu, select Wipe & Reset → Wipe Cache.




4. Confirm the action and restart.

This method helps in 60% of cases when dark wallpaper is caused by a rendering failure, and if you still have a problem after resetting the cache, move on to the next section.

Make sure to back up your data | Charge your phone at least 50% |Close all background apps |Have a charger on hand-->

6. Check for hardware problems

If none of the software methods worked, it may be because the screen or the light controller malfunctioned.

⚠️ Warning: If the wallpaper is dark only in a certain part of the screen (for example, on the edges), or if there are slashes, flickering or broken pixels with them, this is a sign of physical damage to the matrix.

To diagnose a hardware problem:

1. Look at the screen from different angles, and if you tilt the dark areas change intensity, it's the plume of the display.
2. Connect your phone to an external monitor via USB-C → HDMI. If the wallpaper is normal, the problem is in the smartphone screen.
3. Check if there's been any falls or moisture, even a minor impact can damage the backlight.

On Xiaomi models with AMOLED-screens (for example, Xiaomi 13 Pro or Redmi) K50 Ultra) Dark wallpapers can be caused by pixel burnout. To check this, install a full white wallpaper, so if you see the contours of old images, the matrix is worn out.

7.Extreme measures: reset to factory settings

If all previous methods failed, there is a hard reset. This will delete all data from the phone, so pre-backup through Settings → About Phone → Backup.

Instructions for discharge:

1. Go to Settings → About the phone → Reset settings.
2. Choose to erase all data.
3. Enter a password (if required) and confirm the action.
4. After rebooting, set your phone up as new and check the wallpaper.

⚠️ Note: On some models (POCO X3 NFC, Redmi 9A) After the reset, you may need to re-assign your Mi Account. Make sure you remember your login and password!

If even after the wallpaper is reset, the problem is exactly in the hardware (screen, plume, controller).
