The camera app on Android may stop working at the most inopportune moment: before an important selfie, while shooting a video, or when scanning a QR code. Instead of the usual interface, you see a black screen, an error “Failed to connect to the camera", a failure message, or the application just closes immediately after startup. In 90% of cases, the problem is solved without contacting a service center - just follow a few simple steps.

In this article we will analyze all possible causes of failure from software conflicts to hardware faults, and also give step-by-step guide troubleshooting. We will pay special attention Samsung, Xiaomi, Realme and Google Pixel modelsto where camera errors occur most often. If your device is not included in this list, do not worry: most methods are universal and work on any Android smartphone.

Before starting repairs, check whether the failure is temporary. For example, On devices with a Qualcomm Snapdragon 8 Gen 1 processor (2022), there is a known problem with camera drivers after updating to Android 14 - in this case, only rolling back the firmware or waiting for a patch from the manufacturer helps.. If the error appeared after installing a new application or crashing the phone, the reasons and solutions will be different.

1. Rebooting the smartphone is the first diagnostic step.

It sounds trivial, but more than 30% of camera failures on Android they are eliminated by a regular reboot. The fact is that the camera module is controlled not only by the application itself, but also by system services (media.server, cameraserver). If one of them freezes, the camera will stop responding, although it physically remains operational.

How to properly reboot the device:

  • 🔄 Soft reboot: hold down the power button, select “Restart” (or “Restart”). Wait 30–60 seconds.
  • 🔋 Forced reboot (if the screen does not respond): press the power button + volume down for 10–15 seconds until the manufacturer's logo appears.
  • 📱 For Samsung with Bixby button: press power + Bixby + volume down at the same time.

After rebooting, immediately check the camera. If the problem persists, proceed to the next step. Please note: on some devices (for example OnePlus 9 Pro or Xiaomi 13) after a forced reboot, face unlock may be reset - this is normal and is not associated with a camera malfunction.

2. Clearing the cache and data of the Camera application

The cache of the camera application accumulates temporary files: thumbnails, shooting settings, autofocus data. If these files become damaged, the application begins crashing, slowing down or showing a black screen. Clearing the cache is a safe procedure that does not delete your photos or videos, but often solves the problem.

Instructions:

  1. Open Settings → Applications (or "Manage applications").
  2. Find the application "Camera" (on some devices it may be called Camera, MIUI Camera or Samsung Camera).
  3. Go to Storage → Clear cache.
  4. If that doesn't help, click Clear data (⚠️ this will reset the camera settings, but will not delete media files).

On Samsung Galaxy after clearing the data, you may need to re-adjust the shooting resolution and enable functions like Super Steady or Director’s View. On Xiaomi i Redmi sometimes additional clearing of the cache for the application helps, since it is crowded integrated with the camera module. "Gallery", as it is tightly integrated with the camera module.

3. Checking permissions for the camera application

Android strictly controls application access to the hardware. modules. If permissions for the camera were accidentally disabled (for example, after a system update or a settings reset), the application will not be able to use it. Also, some permission managers (like App Ops or built-in functions on Huawei) may block access.

How to check and restore permissions:

  • 📸 Primary resolution: Settings → Applications → Camera → Permissions. Make sure Camera, Microphone (for video recording) and Storage (for saving photos) are turned on.
  • 🔒 Special access: on some devices (for example, Oppo Reno or Vivo) you need to additionally allow access to Settings → Privacy → Special access → Camera access.
  • 🛡️ Antiviruses and optimizers: Applications like Clean Master, Avast or 360 Security can block the camera. Try disabling them temporarily.
⚠️ Attention: On devices with Android 12+ and the function Approximate location the camera may not work if the application has restrictions on access to geodata. Enable Exact location in the permission settings.
Manufacturer Where to look permissions Additional settings
Samsung Settings → Applications → Camera → Permissions Check Advanced settings → Access to the camera for third-party applications (for example, Instagram).
Xiaomi/Redmi/Poco Settings → Privacy → Permissions → Camera Disable Autostart for optimizers in Settings → Battery.
Google Pixel Settings → Applications → Google Camera → Permissions Check Settings → System → For developers → Inactive applications (the camera should not be there).
Huawei/Honor Settings → Applications → Camera → Permissions Enable Run in background for the camera in the battery settings.

4. Updating or reinstalling the camera application

Manufacturers regularly release updates for the standard camera application, fixing bugs and adding new features. If your version is outdated or corrupted, it may cause crashes. Also on some devices (for example Samsung Galaxy S22 or OnePlus 10 Pro) the camera is updated separately from the system via Galaxy Store or Oppo App Market.

How to update or reinstall the camera:

  1. Open Google Play Market and find the camera application (for example, Google Camera, Samsung Camera or MIUI Camera).
  2. If there is an “Update” button, press it. If there is no button, it means there is no update or the camera is built into the firmware.
  3. For reinstallation:
    • 📱 On Samsung: uninstall updates in Settings → Applications → Camera → ⋮ → Uninstall updates.
    • 📱 On Xiaomi: download the latest version MIUI Camera from the official website miui.com (section "Support").
    • 📱 On Google Pixel: the camera is updated only through Play Market.
⚠️ Attention: Do not install modified versions of the camera application (for example, GCam for unofficial support) on top of the standard software. This may lead to complete. module malfunction and will require resetting the settings.
💡

If after the update the camera begins to work worse (for example, photo quality has deteriorated), try rolling back to the previous version. To do this, download the APK from a trusted source (for example, APKMirror) and install manually, after removing the updates.

5. Checking for conflicts with other applications

The camera may not work due to conflicts with other appsthat also use its module. Most often, problems are caused by:

  • 🔍 QR code scanners (for example, QR & Barcode Scanner), which “occupy” the camera in the background.
  • 🎮 Games with AR functions (Pokémon GO, Harry Potter: Wizards Unite).
  • 📹 Streaming applications (Twitch, YouTube Studio) or video calls (Zoom, Google Meet).
  • 🛡️ Antiviruses and VPNthat block access to hardware modules.

How to identify and eliminate conflict:

  1. Close all applications through Recent → Close all.
  2. Restart the phone in safe mode (press and hold the power button, then select “Safe Mode” Only system ones work in this mode). applications.
  3. Check the camera. If it works, the problem is in one of the installed applications.
  4. Uninstall or disable recently installed apps one by one until you find the culprit.

On Samsung Galaxy and Xiaomi there is a built-in conflict diagnostic function: go to Settings → Device care → Diagnostics (or Security → Optimization) and run a check for incompatible applications.

How to enable safe mode on different devices

Samsung: Hold the power button → hold "Power off" → click "Safe Mode." Xiaomi/Redmi: Press the power button → hold “Power off” → “OK” to enter safe mode. Google Pixel: Press the power button → hold “Power off” → “Safe mode.” Huawei: Hold down the power button → hold “Power off” → “Reboot in safe mode.”

6. Resetting the camera and system settings

If the previous methods did not help, the problem may lie in system settingsrelated to the camera. Resetting will not delete your photos or videos, but will return all shooting settings (resolution, white balance, HDR settings) to factory settings.

How to reset the camera settings:

  • 📷 On Samsung: open the application “Camera” → click on ⚙️ “Settings” → “Reset settings”.
  • 📷 On Xiaomi: Camera settings → Advanced → Restore default settings.
  • 📷 On Google Pixel: reset is only available through resetting all system settings (see below).

If resetting the camera settings did not help, try resetting all network settings (does not delete data, but resets Wi-Fi, Bluetooth and mobile network):

  1. Go to Settings → System → Reset settings.
  2. Select “Reset network settings” (or “Reset Wi-Fi, mobile network and Bluetooth”).
  3. Confirm the action and restart the device.

As a last resort, you may need Full reset (will delete all data, including photos and applications!). Before doing this, be sure to make a backup copy:

Settings → System → Reset settings → Delete all data (factory reset)
⚠️ Attention: On some devices (for example, Realme GT or Oppo Find X) after the reset, you may need to re-activate the camera through the developer settings. To do this, go to Settings → About phone → Build number (press 7 times), then to Settings → System → For developers and enable the option USB debugging (even if you do not connect the phone to the PC).

7. Checking for hardware faults

If software methods do not work, the cause of the failure may be hardware. Here are the signs indicating a physical malfunction:

  • 🔍 The camera does not work in all applications (including Instagram, Snapchat, Google Meet).
  • 💥 Appear on the screen artifacts (color stripes, spots, distortions).
  • 🔊 When you try to start the camera, you hear a click or scratching (may indicate damage to the stabilization mechanism).
  • 💧 The phone fell into water or was subjected strong impacts (even if there is no external damage).
  • 🔋 The camera stopped working after replacing the battery or screen (possibly damaged cable).

How to diagnose a hardware fault:

  1. Check the camera through diagnostic mode:
    • On Samsung: dial #0# → select Mega Cam or Front Cam.
    • On Xiaomi: dial ##4636## → "Equipment testing" → “Camera.”
    • On Google Pixel: use the application Manual Camera Compatibility Test from Play Market.
  • If the camera also does not work in diagnostic mode, there is a problem hardware.
  • Inspect the lens for cracks, scratches or moisture under the glass.

    • The most common hardware failures:

    Problem Symptoms Solution
    Damaged camera cable The camera does not work at all, but the flashlight is on Replacement of the cable at the service center (~1,500–3,000 RUR)
    The camera module has failed Artifacts in the photo, black screen, error initialization Module replacement (~3,000–8,000 ₽ depending on the model)
    Moisture getting under the lens Glass fogging, blurry pictures, "Camera busy" error Drying in the service (sometimes self-drying in rice for 24–48 hours helps)
    Damage to the stabilizer (OIS) Grazing when focusing, image shaking Replacing the camera module (the stabilizer cannot be repaired separately)

    If you you suspect a hardware malfunction Do not try to disassemble the phone yourself - modern smartphones have fragile cables and adhesive seals that are easy to damage. Contact an official service center or a trusted repair service.

    💡

    If the camera stops working after being dropped or exposed to moisture, every hour of delay increases the risk of contact corrosion. The sooner you take your phone to a service center, the higher the chance of saving the module without a complete replacement.

    8. Alternative solutions and temporary workarounds

    If the camera still does not work, but you urgently need to take a photo, use these temporary solutions:

    • 📱 Third-party applications: install an alternative camera from Play Market, for example:
      • Open Camera (open source, supports most devices).
      • Footage (for professional shooting, if the standard camera is buggy).
      • GCam (only for supported models, requires manual configuration).
    • 💻 Connecting to a PC: if the camera does not work on the phone, but is needed for video calls, connect the phone to the computer and use it as a webcam via DroidCam or Iriun Webcam.
    • 🔄 Rolling back the firmware: if the camera stops working after updating Android, try rolling back to the previous version (look for instructions on the forums 4PDA or XDA Developers for your model).

    For Samsung Galaxy there is a special mode Camera Repair Modethat can temporarily restore the camera:

    1. Open the “Phone” application and dial *#9900#.
    2. Select SysDump → Camera Dump.
    3. Restart the phone.

    This mode resets temporary camera data and sometimes helps with software failures. However, it will not fix hardware failures.

    How to use GCam on unofficially supported devices

    1. Download the version of GCam adapted for your model (look for Celso Azevedo’s blog or 4PDA).

    2. Install the APK file (allow installation from unknown sources in the security settings).

    3. In the GCam settings, select the correct config (for example, for Snapdragon 865 or Mediatek Dimensity 1200).

    4. Disable the standard camera in the application settings (do not delete it!).

    ⚠️ Risk: GCam can cause overheating or degrade photo quality if the config is selected incorrectly.

    FAQ: Frequently asked questions about camera failures on Android

    ❓ The camera says “Could not connect to the camera.” What should I do?

    This error indicates an access conflict. Try:

    On Xiaomi i Redmi this error sometimes appears due to the function Privacy → Special permissions → Access to the camera —check that there are no restrictions.

    ❓ After updating Android, the camera began to slow down?

    Updates often bring new bugs. Try:

    • 🔄 Roll back to the previous firmware version (if you have a backup).
    • 📱 Install an alternative camera application (for example, Open Camera).
    • 🔧 Enable For developers → Disable hardware overlays (sometimes speeds up the camera).
    • 📲 On Samsung try resetting the camera settings via #0# (see section 7).

    If the brakes appeared on Google Pixel after updating to Android 14, wait for the patch - such problems are usually fixed within 1-2 months.

    ❓ The camera works, but the photos turn out blurry or with artifacts. What's the matter?

    Reasons for blurry photos:

    • 🧹 Dirt on the lens: wipe the camera glass with a soft cloth (do not use alcohol!).
    • 🔍 Problems with autofocus: try manually focusing by touching the screen. If this does not help, the laser or phase module may be damaged. autofocus.
    • 💧 Moisture under the glass: if the phone has been dropped into water, disassembly and drying is required.
    • 📱 Software failure: reset the camera settings or install another application (for example, Footage) for verification.

    Artifacts (colored stripes, spots) usually indicate damage to the matrix or a plume. In this case, only replacing the module will help.

    ❓ Is it possible to repair the camera yourself?

    Independent repair is possible only in two cases:

    1. 🔧 Cleaning the lens: if dust has accumulated under the glass, you can carefully remove it (heating with a hairdryer) and clean. Risk: damage to the adhesive seal, which will lead to dust getting inside the module.
    2. 🔌 Replacing the cable: if you have soldering experience and a suitable cable (for example, for Samsung Galaxy S20 or Xiaomi Redmi Note 10). Risk: damage to the motherboard.

    ❌ It is not recommended to do it yourself:

    • Changing the matrix or camera module (requires calibration and special equipment).
    • Repairing the stabilizer (OIS) is a precision mechanism.
    • Clean the contacts with alcohol (you can damage the coating).

    If you are not confident in your skills, it is better to contact a service center. The cost of camera repair in official centers:

    • Samsung: from 2,500 ₽ (loop) to 7,000 ₽ (module).
    • Xiaomi: from 1,500 ₽ (loop) to 5,000 ₽ (module).
    • Google Pixel: from 4,000 ₽ (diagnostics + repair).
    ❓ The camera does not work after replacing the screen. What to do?

    This problem occurs when the display is replaced unqualifiedly. Reasons:

    • 🔌 The camera cable is damaged (passes next to the screen cable).
    • 🔧 Inappropriate screen: some cheap spare parts conflict with the camera (especially on Samsung s AMOLED-displays).
    • 💡 Proximity sensor disabled: on some models it is related to the operation of the camera.

    Solutions:

    1. Go back to the workshop where the screen was changed and ask to check the cables.
    2. If the screen is original, but the camera does not work, the technician may have forgotten to connect the camera connector - this can be fixed in 10 minutes.
    3. On Samsung Galaxy S i Note after replacing the screen, it is sometimes required camera calibration through the service menu (#0# → Sensor Test).

    ⚠️ If the master refuses to admit guilt, demand an acceptance certificate indicating “checking the camera - it works.” Without this document, it will be possible to prove his guilt difficult.
