Camera Not Working
How to fix a camera that is not detected or shows a black screen. Covers permissions, driver updates, and hardware troubleshooting on Mac and Windows.
When your camera is not working, start with the simplest cause: a physical privacy shutter or cover blocking the lens. After that, check permissions, close apps that may be holding the camera, and look at drivers if nothing else works. Test your camera at thetest.com/camera to verify it is working.
- Check the physical camera — if your laptop has a privacy shutter or slide cover, make sure it is open. A blocked lens shows a black image, not an error
- Open System Settings > Privacy & Security > Camera
- Make sure the app you are using has its toggle turned on. If the app is not listed, open it and try to use the camera to trigger the permission prompt
- Quit any other app that might be using the camera (FaceTime, Zoom, Photo Booth, etc.) — macOS generally only allows one app to use the camera at a time. The camera indicator light being on when you are not in a call is a sign something else has it
- If the camera still does not work, check that it is recognized by the system: go to Apple menu > About This Mac > More Info > System Report and look under Camera. If nothing is listed, the hardware may have a problem
- Restart your Mac — this releases any app that may have locked the camera
- If you use an external USB camera, try unplugging it and plugging it into a different port. Make sure the camera works on another computer to rule out a hardware failure
Frequently Asked Questions
What if my laptop has a privacy shutter I forgot about?▾
It is more common than you think. Most modern laptops have a small physical slider next to the camera lens. When closed, the camera shows a completely black image (not an error message). Look for a small tab you can slide to the side. Some Lenovo and HP laptops use a keyboard shortcut instead — look for a key with a camera icon, often toggled with Fn.
Can I use my phone as a webcam?▾
Yes. On Mac, Continuity Camera is built in — just hold your iPhone near your Mac and it appears as a camera option in most apps (requires macOS Ventura or later and iOS 16+). On Windows, apps like Camo or the Link to Windows / Phone Link app with supported Samsung/Android devices can turn your phone into a webcam over USB or Wi-Fi.
Why is my camera image dark or grainy?▾
Low light is the most common cause. Built-in laptop cameras have tiny sensors and struggle in dim environments. Try facing a window or adding a desk lamp aimed at your face (not at the camera). If the image is grainy even in good light, check your app's video settings for a resolution or quality option — some apps default to lower quality. Cleaning the lens with a soft cloth also helps more often than you would expect.
