If your smartphone is sending messages like “Camera is busy with another app,” or just hanging out when you start, don’t rush to repair it. In most cases, the decision takes no more than 10 minutes.

1. Software failures: when firmware or applications are to blame

The most common cause of camera error on Xiaomi is software conflicts, which can be a failure in the standard Camera application, a conflict with other programs (for example, messengers or social networks), and the consequences of a failed update. MIUI.

The first thing you need to do is reboot your phone, which is a basic step, but it helps in 30 percent of cases, especially if the error occurred after long-term use of the device.

2. Hardware problems: when the "iron" is to blame

If software methods fail, the problem may be a physical malfunction of the camera, most often due to:

• 💥 Falls or impacts: Even a minor mechanical impact can displace the lens or damage the plume connecting the camera to the motherboard.
• 🌊 If the phone was in water (even briefly), corrosion could damage the contacts of the camera module.
• 🔌 Oxidation of connectors. Over time, the contacts of the camera plume become oxidized, which leads to loss of communication with the processor.
• 📸 Lens contamination: Dust, fingerprints or scratches on glass can block autofocus and cause errors.

How to check the hardware serviceability:

1. Examine the lens for cracks, scratches, or dirt. wipe it with a soft napkin (no alcohol!).
2. Try to start the camera in safe mode (press the power button). → «Safe Mode. If this mode is running, the problem is the software conflict.
3. Connect your phone to your PC and check if the camera is identified as an input device (via Windows Device Manager).

If you suspect a physical breakdown but are not sure what caused it, use the diagnostic code to test the camera:

##6484##

This code works on most Xiaomi models and allows you to check the performance of the front and main cameras, as well as other sensors (gyroscope, accelerometer).

⚠️ Warning: Don't try to disassemble your phone yourself to check the camera plume if you don't have experience. IP-certification (for example, Xiaomi 13 Pro) disassembly can violate the tightness, which will lead to loss of water protection.

3. Conflicts with access rights and security settings

Sometimes, a camera error on Xiaomi is due to access restrictions that the user accidentally or intentionally set.

• 🔒 Disabled permissions for the Camera application (access to the camera, microphone, storage).
• 🛡️ Active mode "Incognito" in the MIUI, This will block access to the camera for all applications.
• 📵 Background activity limitations that prevent the camera from initializing.
• 🔐 Security policies (e.g., corporate phones with MDM).

How to check and correct:

1. Open the Settings. → Annexes → Application management → Camera. → Permissions and make sure all switches are active.
2. Check the Settings. → Confidentiality → Special access → Access to the camera – there should be no bans for system applications.
3. Turn off Incognito mode (if enabled): swipe down the notification panel and check the mask icon.

Prepare the cable. USB PC-->

5. overheating of the phone and its effect on the camera

Many Xiaomi users are unaware that overheating can cause camera errors when the CPU temperature is above 60-70.°C, the system automatically disables resource-intensive modules, including the camera, to prevent chipset damage.

How to understand that the problem is overheating:

• 🌡️ Phone hot to the touch (especially in the processor area).
• 🔋 The battery goes down quickly even without active use.
• ⚡ Performance drops, apps start to slow down».
• 📵 The camera shuts down a few seconds after launch.

What to do:

1. Let the phone cool down – turn it off for 15-20 minutes.
2. Close all background apps, especially games and instant messengers.
3. Remove the cover - it can block the heat sink.
4. Check the temperature through the app AIDA64 or CPU Monitor.
5. Clean the phone of dust (especially the charging and speaker connector).

If the phone is warm even in plain, it may indicate:

• 🔋 Battery wear (check battery status in AccuBattery).
• 🛠️ Thermopaste malfunction (relevant for phones over 2 years old).
• 📱 Problems with the motherboard (for example, after a fall).

⚠️ Warning: Do not use your phone in the sun or near heat sources (e.g. on a torpedo in a car in summer) Overheating above 70°C can irreversibly damage the camera matrix and it will have to be changed.

💡

If the camera is only disabled when shooting a long video in the 4K Or night mode, the problem is definitely overheating. 1080p or use an external cooler.

6. Viruses and malware
