Android Camera Not Working or Black Screen Fix

Quick Answer

When the Android Camera app opens but shows a black preview, first close other apps that may be using the camera, restart the phone, and test both the front and rear cameras.

If the camera works in one app but not another, check that app’s camera permission and settings. If every app shows a black screen, continue with Camera app cache, software updates, Safe Mode, and manufacturer diagnostics.

A failed camera module or software conflict is possible, but neither can be confirmed from a black preview alone.

This guide applies when the phone itself is working and only the camera preview is black. If the entire phone display is black or the phone will not turn on, use a separate startup or display troubleshooting path.

Safety Check

Stop DIY troubleshooting and arrange professional inspection when:

• The camera stopped working immediately after a hard drop.
• The phone was exposed to liquid.
• The camera glass is cracked or missing.
• The phone is bent or the back panel is separating.
• The device is extremely hot.
• You notice swelling, smoke, sparks, or a burning or chemical smell.
• The camera makes loud repeated clicking or grinding noises.
• Important data is not backed up and the next proposed procedure may erase app or device data.

Do not open the phone, press on the camera module, insert tools around the lens, apply cleaning liquid inside the camera opening, or install unofficial camera firmware.

Choose the Symptom That Matches

What you see	What it may suggest	Next safe step
Camera app opens to a black preview	Temporary Camera app failure, blocked camera access, app conflict, or hardware failure remains possible	Restart and test another app
Only one app shows a black camera	Permission, app settings, or an app-specific problem becomes more relevant	Check that app’s camera permission
Front camera works but rear camera is black	A rear-camera-specific problem becomes more plausible	Restart and test the rear camera in another supported app
Rear camera works but front camera is black	A front-camera-specific problem becomes more plausible	Check for obstruction and test another app
Every camera app fails	System-level software or hardware becomes more plausible	Update Android and test Safe Mode
Camera closes immediately	Camera app data, software conflict, temperature, or hardware may be involved	Restart and clear Camera cache
“Camera in use” or similar message appears	Another app may still be accessing the camera	Close recent apps and restart
Camera failed after a drop or liquid exposure	Physical damage becomes more plausible	Back up data and request inspection
Camera works in Safe Mode	A downloaded app becomes more likely	Remove recently installed apps
One camera lens consistently remains black	A specific camera path or module may be affected	Run manufacturer diagnostics

These results narrow the possible causes. They do not identify the exact failed component.

1-Minute Safe Checks

Complete these checks before resetting any settings:

1. Close the Camera app completely.
2. Close video-call, QR scanner, social media, flashlight, and document-scanner apps.
3. Remove any case, lens cover, privacy cover, or accessory blocking the cameras.
4. Check that the front and rear lenses are not covered by dirt, condensation, stickers, or damaged glass.
5. Wipe the exterior lens glass gently with a clean microfiber cloth.
6. Lock and unlock the phone.
7. Open the Camera app again.
8. Switch between the front and rear cameras.
9. Restart the phone.
10. Test the camera before reopening other apps.

Do not repeatedly tap the camera-switch button when the application is frozen. Close the app or restart the phone instead.

Fix 1: Restart the Camera App and Phone

SAFE FIRST CHECK

Use This When

Use this first when:

• The camera suddenly became black.
• The Camera app freezes or closes.
• The problem appeared without a drop or liquid exposure.
• Another app recently used the camera.

Why It May Help

A camera process or another application may temporarily fail to release access to the camera. Closing the affected apps and restarting the phone reloads the Camera app and related Android services.

Google and Samsung both include restarting as an early camera troubleshooting procedure.

Steps

1. Open the recent-apps screen.
2. Close the Camera app.
3. Close video-call, social media, scanner, and other camera-using apps.
4. Wait several seconds.
5. Reopen the Camera app.
6. If the preview remains black, restart the phone normally.
7. After startup, open the Camera app before opening other applications.
8. Test the front and rear cameras.

Expected Result

The camera preview should appear normally after the app or phone restarts.

What the Result Means

• Normal operation suggests a temporary process or application problem may have contributed.
• Repeated failure does not confirm hardware damage.
• If only one application still fails, troubleshoot that application.
• If every application fails, continue with the comparison tests.

Fix 2: Compare the Front Camera, Rear Camera, and Other Apps

DIAGNOSTIC TEST

Use This When

Use this test when the Camera app opens but displays a black image.

Steps

1. Open the built-in Camera app.
2. Test the main rear camera.
3. Switch to the front camera.
4. Record which camera works.
5. Open a trusted app that legitimately uses the camera, such as a video-call or QR-scanning app.
6. Allow camera access when Android asks.
7. Test the main rear and front cameras when the app supports switching.
8. Close the test app afterward.

Do not install several unknown “camera test” or “camera repair” applications. Use an app you already trust or the manufacturer’s diagnostic tool.

What the Result Means

• Built-in Camera works, but one downloaded app fails: The downloaded app’s permission, settings, files, or compatibility becomes more relevant.
• Front camera works, but the main rear camera fails everywhere: A rear-camera-specific software or hardware problem becomes more plausible.
• Rear camera works, but the front camera fails everywhere: A front-camera-specific problem becomes more plausible.
• Both cameras fail in every app: A system-level software problem or hardware failure becomes more plausible.
• The camera works after closing one app: That app may have contributed, but one successful test does not prove a permanent conflict.

Google’s Pixel camera guidance recommends checking other camera apps; failure across other apps can support moving toward repair evaluation.

Fix 3: Check Camera Access and App Permissions

OFFICIALLY DOCUMENTED STEP

Use This When

Use this when:

• A video-call, scanner, banking, or social media app shows a black camera.
• The app reports that permission is denied.
• Camera access was recently changed in Android’s privacy settings.
• The built-in Camera app works but another app does not.

Why It May Help

Android allows users to deny camera permission to individual applications. Supported Android versions may also provide a Camera access privacy control that disables camera access for applications and services.

Google documents both per-app camera permissions and the system Camera access control. Menu names may differ by Android version and manufacturer.

Check the App’s Camera Permission

1. Open Settings.
2. Tap Apps.
3. Select the affected application.
4. Tap Permissions.
5. Select Camera.
6. Choose an available permission such as Allow only while using the app.
7. Close Settings.
8. Reopen the affected app.
9. Test the camera.

Do not grant camera permission to an application that does not need camera access for its stated function.

Check the System Camera Access Control

On supported Android versions:

1. Open Settings.
2. Open Security & privacy or Privacy.
3. Look for Privacy controls.
4. Check whether Camera access is enabled.
5. Turn it on only when you intend to let approved applications use the camera.
6. Reopen the Camera app and test again.

The exact location can also appear in Quick Settings on some phones.

What the Result Means

• If one app works after permission is restored, its denied permission was involved.
• If the built-in Camera app remains black, continue with Camera app troubleshooting.
• If permission turns off again, check device-management, parental-control, security, or work-profile restrictions.
• Permission changes cannot repair a physically damaged camera module.

Fix 4: Force Stop the Camera App and Clear Its Cache

OFFICIALLY DOCUMENTED STEP

Use This When

Use this when:

• Restarting did not help.
• The Camera app freezes, crashes, or remains black.
• The phone has no physical-damage or liquid warning signs.
• Enough of Android remains responsive to open Settings.

Why It May Help

The Camera app stores temporary files. Clearing its cache removes those temporary app files without using the more destructive Clear storage or Clear data command.

Google’s current Pixel camera troubleshooting guidance includes clearing the Camera app cache.

Steps

Menu names vary, but the normal path is:

1. Open Settings.
2. Tap Apps.
3. Select Camera.
4. If Camera is not visible, tap See all apps or Show system apps.
5. Tap Force stop when available.
6. Confirm the action.
7. Tap Storage & cache or Storage.
8. Select Clear cache.
9. Reopen the Camera app.
10. Test the front and rear cameras.

An alternative on some devices is:

1. Touch and hold the Camera app icon.
2. Tap App info.
3. Open Storage & cache.
4. Tap Clear cache.

Expected Result

The Camera app should create fresh temporary files and open normally.

What the Result Means

• Improvement suggests temporary Camera app files may have contributed.
• No improvement does not prove hardware failure.
• Do not repeatedly clear the cache when the same failure immediately returns.
• Continue with updates and Safe Mode.

Fix 5: Update the Camera App and Android

OFFICIALLY DOCUMENTED STEP

Use This When

Use this when the phone can still connect to the internet and navigate Settings.

Why It May Help

Camera application updates and Android system updates can contain compatibility corrections, stability improvements, and manufacturer-specific camera changes.

Google includes both Camera app updates and Android system updates in its Pixel camera troubleshooting sequence.

Update the Camera App

1. Open Google Play Store.
2. Tap your profile icon.
3. Tap Manage apps & device.
4. Open Updates available.
5. Look for the phone’s Camera app.
6. Install an available official update.
7. Restart the phone.
8. Test the camera.

Some manufacturers update the Camera app through their own app store or system updater rather than Google Play.

Update Android

1. Connect to reliable Wi-Fi.
2. Make sure the battery has sufficient charge.
3. Open Settings.
4. Search for System update or Software update.
5. Check for an official update.
6. Read the installation information.
7. Install the update.
8. Allow the phone to restart.
9. Test the Camera app before changing other settings.

What the Result Means

• Improvement after an update suggests software may have contributed.
• Failure after an update does not establish that the update caused physical damage.
• Do not install unofficial camera APKs, drivers, firmware, or update packages.
• If the failure began immediately after an official update, report it through the manufacturer’s support channel.

Fix 6: Test the Camera in Safe Mode

DIAGNOSTIC TEST

Use This When

Use Safe Mode when:

• The problem began after installing an application.
• A downloaded camera, flashlight, scanner, security, overlay, or social media app may be involved.
• Both the phone and display operate normally.
• There is no serious physical damage.

Why It May Help

Safe Mode temporarily disables downloaded applications. If the built-in Camera app works in Safe Mode, a downloaded app becomes more likely to be involved.

Safe Mode is a diagnostic test, not a guaranteed repair. Google includes Safe Mode in its Pixel camera troubleshooting process.

Steps

Safe Mode entry procedures differ by manufacturer.

On many Android phones:

1. Open the power menu.
2. Touch and hold Power off or Restart.
3. Select Safe Mode when the option appears.
4. Wait for the phone to restart.
5. Confirm that Safe mode appears on the screen.
6. Open the built-in Camera app.
7. Test the front and rear cameras.
8. Restart normally to exit Safe Mode.

Use the manufacturer’s official procedure when the Safe Mode option does not appear. Do not guess model-specific button combinations.

What the Result Means

• Camera works in Safe Mode: A downloaded application becomes more likely.
• Restart normally.
• Remove recently installed or updated applications one at a time.
• Restart and test after each removal.
• Camera still fails in Safe Mode: A downloaded app becomes less likely, but hardware failure is not automatically confirmed.
• Continue with manufacturer diagnostics or service evaluation.

Fix 7: Use Manufacturer Diagnostics and Camera Reset Options

CONDITIONAL STEP

Use This When

Use this when basic checks, cache clearing, updates, and Safe Mode have not resolved the problem.

Manufacturer Diagnostics

Some Android manufacturers include built-in hardware diagnostics.

For supported Samsung Galaxy devices:

1. Open Samsung Members.
2. Tap Support.
3. Open the available phone diagnostics.
4. Select Camera.
5. Run the test.
6. Record the result or error message.

Samsung states that the diagnostic feature requires Samsung Members and that menus can vary by device, software, and app version.

Other manufacturers may provide diagnostics through:

• A built-in support app
• Device Help
• My Device
• Support or Care applications
• An authorized service-center test

Use only the manufacturer’s official tool for the exact device.

Clear Camera App Data on Supported Samsung Devices

Samsung’s official Galaxy instructions provide a Clear data procedure for Camera app errors. Samsung states that this resets Camera settings but does not delete photos and videos on supported Galaxy devices.

Samsung Galaxy steps:

1. Open Settings.
2. Tap Apps.
3. Select Camera.
4. Tap Storage.
5. Tap Clear data.
6. Read the confirmation.
7. Confirm the reset.
8. Open Camera.
9. Reconfigure any required Camera settings.

For other Android manufacturers, do not assume that clearing Camera data has identical effects. Read the confirmation screen and use the manufacturer’s official guidance.

What the Result Means

• A passed test does not guarantee that an intermittent hardware problem is absent.
• A failed test should be documented before contacting support.
• If one physical camera repeatedly fails diagnostics, service inspection becomes more appropriate.
• Do not open the phone or buy a replacement camera module based only on one software result.

When the Problem May Be Hardware-Related

A camera module, connector, stabilization mechanism, or another internal component becomes more plausible when:

• The camera failed immediately after a hard drop.
• Liquid exposure occurred.
• One camera remains black in every supported app.
• Both cameras fail in the built-in app and other trusted apps.
• The failure continues in Safe Mode.
• Manufacturer diagnostics report a camera fault.
• The Camera app reports that no camera is detected.
• The camera repeatedly shakes, clicks loudly, or cannot stabilize.
• The problem began after the phone was opened or repaired.
• The camera glass is cracked and moisture or debris may have entered.
• Software steps provide no improvement.

These observations do not identify the exact failed component. A black preview alone cannot confirm whether the camera sensor, module, connector, board, app, or system service is responsible.

When to Stop DIY Troubleshooting

Contact the manufacturer or a qualified repair provider when:

• The phone has impact or liquid damage.
• One or more cameras are not detected.
• The camera fails across every app and Safe Mode.
• A manufacturer diagnostic reports a fault.
• The device is still under warranty.
• The back panel or screen is separating.
• The phone becomes dangerously hot.
• Important data has not been backed up.
• The camera stopped working after a previous repair.
• The problem prevents identity verification, banking, work, or another essential task.

Back up important data before handing the phone over for service when the device remains usable.

Common Mistakes

• Assuming that a black camera preview confirms a failed camera module
• Confusing a black camera preview with an entirely black phone display
• Granting camera access to untrusted applications
• Installing “camera repair” or “camera driver” apps
• Downloading unofficial Camera APK files
• Clearing all phone data before testing permissions and Safe Mode
• Repeatedly clearing Camera data without checking the result
• Opening a sealed phone without proper diagnosis
• Pressing or tapping the camera area
• Applying liquid cleaner around damaged lens glass
• Ignoring a recent drop or liquid exposure
• Buying a replacement camera module before identifying which camera path failed
• Assuming one Safe Mode failure proves hardware damage
• Assuming one successful restart proves that the problem is permanently fixed

How This Guide Was Verified

Last technically checked:

August 2, 2026

Research method:

Current Google Android, Google Pixel, and Samsung Philippines support documentation was opened. Page titles, camera troubleshooting procedures, permission controls, data-reset warnings, diagnostic instructions, device limitations, and clean destination URLs were checked.

Physically tested:

No documentation reviewed.

Applies to:

Android phones and tablets where the device display and operating system work, but the built-in Camera app or another camera-using app shows a black preview, crashes, or cannot access a camera.

Important limitation:

Camera applications, privacy controls, Safe Mode procedures, diagnostics, update systems, available lenses, and reset behavior vary by manufacturer, model, Android version, region, and application. Remote troubleshooting cannot confirm a failed camera module.

Data-loss risk:

Conditional. Restarting, checking permissions, clearing cache, updating, testing other applications, and Safe Mode are normally non-destructive. Clearing Camera data can reset application settings. A factory-reset procedure is not included.

Final Steps

• Start by closing other camera-using apps, restarting the phone, and comparing the front camera, rear camera, and another trusted application.
• When only one app fails, check its camera permission, cache, and updates. When the built-in Camera fails across applications, clear its cache, update Android, and test Safe Mode.
• If one camera consistently remains black, the failure continues in Safe Mode, or manufacturer diagnostics report a fault, stop repeating software procedures. Back up important data and arrange manufacturer or qualified professional inspection.
