Why Xiaomi’s camera doesn’t turn on: a full analysis of the causes and solutions

You try to take a selfie or run a video call, but the camera on your Xiaomi (whether it’s Redmi Note 12, POCO X5 or flagship Xiaomi 14) stubbornly refuses to turn on? Black screen, error “failed to connect to the camera” or complete lack of reaction to launch — these problems are faced by thousands of users. 80% of the time are not to blame for hardware breakdowns, but software failures that can be fixed on their own in 5-15 minutes.

In this article, we will discuss all possible reasons why the camera on Xiaomi may not work: from the banal contamination of the module to deep system errors. You will receive step-by-step instructions with illustrations (in the form of checklists and tables), warnings about typical user errors, as well as answers to frequent questions. MIUI, These are often the source of camera problems, such as security conflict or hidden restrictions on third-party applications.

If you're not a techie, don't worry: we've explained it as simple as possible, without complicated terms. We've prepared advanced diagnostic methods for advanced users (including ADB commands and log analysis), let's start with the obvious and gradually move on to complex cases.

1. Checking the physical condition of the cell

Before you dig into the settings, make sure the problem isn't mechanical. Start with a visual inspection:

• 🔍 Camera lenses: Light a flashlight - are there scratches, chips or greasy spots on them? Even a microcrack can cause artifacts or complete module failure.
• 📱 Case around camera: If you hit hard, the module mount may shift. Carefully press the area around the lens - if the image appears / disappears, this is a sign of mechanical damage.
• 🚫 Protective films/cases: Make sure nothing blocks the lens. Especially relevant for models with a retractable camera (e.g. Xiaomi Mi Mix 3).

If everything looks good, move on to software diagnostics. Important point: on Xiaomi with an infrared camera (for example, the Redmi K50), problems often arise from dust entering the IR sensor. It can be neatly cleaned with a dry cotton swab (do not use alcohol!).

2.Reboot and basic system actions

It sounds trivial, but a simple reboot helps in 30 percent of cases, because the camera service (android.hardware.camera2) can freeze in the background, especially after:

• 🔄 Updates MIUI (Even minor updates sometimes break compatibility)
• 📱 Install new applications (especially with camera access)
• 🔋 Critical battery discharge (less than 5%)

How to properly reboot:

1. Press the power button for 10 seconds until the menu appears.
2. Select "Reboot" (not "Switch Off"!).
3. After turning on, immediately check the camera in the standard app, not in instant messengers.

If the reboot doesn’t help, try forcefully stopping the camera service:

1. Go to Settings → Applications → Application Management.
2. Find the camera and select Stop.
3. Then click "Storage" → "Clear the cache."

3. Conflicts with applications and permissions

MIUI is known for its aggressive permissions policy, and often the camera doesn't work because the system blocks access to a particular app, such as WhatsApp or Instagram, where there may be a "No Camera Access" error, even though the standard app works.

How to check permissions:

1. Open Settings → Applications → Permissions → Camera.
2. Make sure that the correct application is ticked "Allow".
3. For system applications (e.g., "Camera"), check also Settings → Privacy → Special Access → Camera Use.

Another common problem is conflict with security applications (such as Mi Security or Google Play Protect), which can block camera access for "suspicious" programs.

• Open Mi Security → Scan → Threats and check if there are any blocked applications.
• In Settings → Accounts and Sync → Google → Security settings disable “Device Scanning for Threats” (temporarily).

💡

If the camera is running in a standard app but not in instant messengers, try installing an alternative version of the app (like WhatsApp Business instead of WhatsApp), which sometimes solves the compatibility problem.

4. Reset camera and system settings

If the basic methods didn’t work, it’s time to move on to more radical measures, starting with resetting the camera-only settings (this won’t affect your photos and other data):

1. Open the Camera app.
2. Put it on the gear (⚙️) or swipe left to the settings menu.
3. Find the item "Reset settings" (in some models it is hidden in Additional → Restore default settings).
4. Confirm the reset and restart the phone.

If this doesn’t work, the next step is to reset all system settings (without deleting data):

1. Go to Settings → About the phone → Reset settings.
2. Select "Reset all settings" (not "Delete all data!").
3. After the reboot, check the camera.

Important: Some models (POCO F4, Redmi K60) may require re-activation of the camera licenses after reset (especially for 50MP or 8K video modes).

• Connect to Wi-Fi.
• Open the Camera and wait for the notification to download additional modules.

5. Problems with firmware and updates

Camera errors often appear after the MIUI update. For example, MIUI 14 had a massive black camera screen problem on the Redmi Note 11, and HyperOS (for Xiaomi 13/14) sometimes flies module drivers.

Step 1. Check the firmware version:

1. Go to Settings → About Phone → MIUI version.
2. Remember the build number (e.g., V14.0.5.0.TMCRUXM).
3. Check the forums (4PDA, Xiaomi Community) to see if there are any complaints about this version.

Step 2: Recoil or update the firmware:

• 📥 If your version is not stable (such as beta), upgrade to the last stable version via Settings. → Updating the system.
• 🔙 If the problem appears after the update, try to roll back: Download the previous firmware version from the official Xiaomi website. update.zip And put it in the root of the memory. In recovery, select Install. update.zip.

Step 3: Manual reinstallation of camera drivers (for advanced):

adb shell pm uninstall -k --user 0 com.android.camera


adb shell pm install -r /system/priv-app/MiuiCamera/MiuiCamera.apk

These commands will reinstall the camera system app. Attention: ADB rights and unlocked bootloader are required.

Hardware malfunctions and service repairs

If all software methods have been tried and the camera still doesn't work, it's probably a hardware problem. Here are the most common breakdowns and their signs:

• 🔌 Camera plume detached: It often happens after a fall. Signs that the camera is working, then not (especially when the phone is tilted).
• 💥 Camera module burned: After short circuit (for example, from non-original RAM) Signs - phone warms, camera is not detected in EngineerMode.
• 🌡️ CPU overheating: On the Snapdragon 8 Gen 2 (like the Xiaomi 13 Ultra), the camera for protection turns off when overheating. AIDA64.
• 🔋 Battery malfunction: With severe wear of the battery (capacity) < 70%) may not have enough power for the camera module. → Battery. → Status.

On Xiaomi with multiple rear cameras (like the Redmi Note 11 Pro+ 5G), sometimes only a wide-angle or macro module fails.This often involves getting dust under the lens - try gently cleaning with a dry brush.
