If your camera isn't working, or if you see a message that says "No camera found":
- Turn off your Chromebook, then turn it back on.
- Try using the camera in another app, like Hangouts. If it works in that app, uninstall the app where it doesn't work, then reinstall it.
- Reset your Chromebook.
- Recover your Chromebook.
If you're still having trouble after trying these steps, contact your Chromebook manufacturer.
