How to remove the black background on the phone Xiaomi Redmi: 7 working ways

The black screen on Xiaomi Redmi is a problem faced by users of both budget (Redmi 9A, Redmi 10C) and flagship models (Redmi Note 12 Pro+, Redmi K50). In most cases, it is not a hardware failure, but a software failure that can be fixed on your own, but the causes of black background can range from a banal dark theme error to serious firmware problems or even damage to the display plume.

In this article, we will look at all possible scenarios: when the screen is completely black (but the phone is working), when only the background is displayed without icons, and also situations when the device does not respond to clicks. Separately, we will focus on the unique MIUI 14/15 bugs that cause a spontaneous black background after updates. If your Redmi is on, but the screen does not show the image, do not panic: in 80% of cases, the problem is solved without contacting the service center.

1. Checking the underlying causes: dark topic, energy saving and physical damage

Before you start to do complex manipulations, rule out the obvious reasons. Let's start with a dark topic: in MIUI, it can activate automatically on a schedule or due to a malfunction in settings. Also, a black background often appears when Reading or Eye Comfort is turned on, which reduces brightness to a minimum.

Another culprit is the ultra-low-power mode, which turns off background processes and can reset the interface, leaving only a black screen with a clock, and physical damage (cracks on the screen, moisture) is also worth considering: even if the display is externally intact, a damaged plume can cause such artifacts.

• 🌓 Dark theme: check if it is activated in Settings → Display. → Dark theme. Try switching to light.
• 🔋 Power Saving: Turn off Ultra Battery Saver in Settings → Battery.
• 💧 Moisture/impact: inspect the body for cracks or corrosion under the buttons.
• 🔍 Brightness: The brightness slider may have been knocked down to zero (try to enlarge it manually or through a voice assistant).

⚠️ Attention: If the screen responds to touch (vibrates when pressed) but does not display anything, it is more software problem. If there is no response (even to charging) - it may be a hardware failure.

2.Reboot and forced restart: when the phone "hangs"

The easiest way to get it back up is to force it to restart, which works if the device is getting stuck on a black screen, but it responds to the charging connection (the indicator lights up) or makes notification sounds.

For different Redmi models, the button combinations are different:

If the screen is still black after the reboot, but the phone is making a MIUI start sound, try connecting it to the computer. If the PC detects the device, the problem is exactly software, in which case resetting the settings through Recovery (more on this below) will help.

💡

If the phone doesn’t respond to the buttons, but vibrates when you connect the charger, try leaving it on charge for 30 to 60 minutes. Sometimes a discharged battery blocks the display from turning on.

3. Reset settings via Recovery Mode (without data loss)

If the forced reboot didn't work, the next step is to run in Recovery mode, which is a special menu that allows you to reset settings, clear the cache or reinstall the firmware. Importantly, a regular reset via Recovery doesn't delete user data (photos, contacts, messages), but resets the system settings to factory settings.

To enter Recovery Mode:

1. Turn off the phone (hold the power button for 10+ seconds).
2. Click the combination: For most Redmi: Power button + Volume up. For older models (Redmi 5/6): Power button + Volume up + Volume down.

Mi

From the Recovery menu, select:

• 🔄 Wipe Data → Wipe All Data (complete reset, deletes everything, only use if other methods have not helped).
• 🧹 Wipe Cache (Cache Clearing, Secure for Data).
• 📱 Reboot → Reboot to System (Reboot to Normal Mode).

Turn off the phone completely.|Connect to charging (minimum 30% battery)|Remember the button combination for your model|Backup important data (if the phone is sometimes turned on)-->

⚠️ If after choosing Wipe Cache, the phone hung on the Mi logo for longer 10 Don't interrupt the process! This is normal for some models. 7/8). Wait for the automatic reboot.

4. Update or reinstall firmware through Fastboot

If the black screen appeared after the MIUI update or reset, the problem may be in the damaged firmware, in which case the flashing through the Fastboot mode will help, this method requires a computer and official software from Xiaomi - Mi Flash Tool.

Step-by-step:

1. Download the official firmware for your model (choose the Fastboot version).
2. Install the Mi Flash Tool on your PC.
3. Turn off the phone and put it in Fastboot mode: Power button + Volume down The screen should show the image of a hare in a hat-eared.
4. Connect your phone to your PC through USB-cable (preferably original).
5. In the Mi Flash Tool, select the downloaded firmware and press Flash.

It takes 5-15 minutes. Once it's done, the phone automatically restarts. If the screen is still black, but the device is still making a boot sound, wait 10-15 minutes: the first boot after the firmware can be a long time.

5. Check of the display module and the plume (hardware malfunctions)

If all the software methods have been tried, but the screen is black, the problem may be the hardware.

• 📱 The display plume is a thin cable that connects the screen to the motherboard, and it's damaged by falls or improper disassembly.
• 💡 Screen backlighting – if the image is barely visible in bright light, but in the dark the screen appears off, the backlight inverter is to blame.
• 🔌 Display connector – oxidation or poor contact on the motherboard.

Checking the hardware fault can be as follows:

1. Connect your phone to an external monitor via a USB-C → HDMI adapter (if the model supports DisplayPort Alt Mode). If there is an image on the monitor, the problem is in the screen or the plume.
2. Call your phone from another device, and if you have a call (a vibration or a melody) but the screen doesn't light up, it confirms that the hardware is failing.
3. Hold the flashlight to the screen at an angle, and if you see the faint outlines of the icons in the dark, the backlight is burned.

⚠️ Warning: Self-repair of the plume or replacement of the screen on Redmi with AMOLED-displays (Redmi) K60, Note 12 Pro+) It's best not to do it without experience. These models require color calibration after you change the matrix, otherwise the screen will display the wrong shades.

6. Specific bugs MIUI 14/15: How to Remove Black Background After Updating

MIUI 14 and 15 firmware (especially in early builds) have a massive bug that causes a black background to appear after the upgrade, and it manifests itself as this: the phone turns on, the sounds work, but the screen stays black or only displays iconless wallpaper, and the reason is a malfunction in the miui.systemui service.

Solutions for this case:

• 🔄 Update rollback: If the black screen appears immediately after the update, try rolling back via Recovery (select the previous firmware version).
• 🛠️ Cleaning up System's cache UI: Enter Settings → Annexes → Application management. Find the System. UI (or Launche. Press Storage. → Clear the cache.

Provisional decision

ADB

adb shell pm clear com.miui.home

This will reset the launcher settings (the icons will return, but the widgets will disappear).

The unique MIUI 15 bug: black screen when Super Wallpaper is activated. Some Redmi Note 12 and Redmi K60 users report that when you set the dynamic wallpaper, the screen turns black, but the phone keeps working. Solution: press the power button, wait for the vibration to turn off, then turn on the phone again, the wallpaper will reset to the standard.

💡

If the black screen appears after the MIUI update, never do a full reset (Wipe Data) first! first try clearing the cache or roll back to the previous firmware version.

7.When to contact the service center: signs of serious breakdowns

Not all cases of black screen can be solved by yourself.

• 🔥 The phone overheats (even when it’s off) – this may indicate a short circuit on the motherboard.
• 💦 On the screen, you can see divorces or dwindles - a sign of fluid getting under the display.
• 🔌 The phone does not charge (even when connected to different power units) - a malfunction of the power controller is possible.
• 📵 The screen flickers or shows artifacts before going out – symptoms of damage to a graphics chip or matrix.

If the screen is completely black, but the phone is responding to charging, run the old version through Fastboot (instructions in section 4).
