I allow Web sites access to the camera, but it still appears to be blocked

Web Camera is not working

Hello

I assume by your comment "black screen appears in video call", you are experiencing problems in other camera apps as well, possibly Skype. If your camera isn't working in any applications this is indicative of a camera driver issue. Please try the steps
listed here to resolve your issue:

Windows help and learning

If your issue isn't resolved after running the steps, please report back with your camera make and model and the driver information you aquire from step 3.

Thanks,

If you have the camera connected to the computer, I would suggest that you disconnect the camera and then try to open the Camera app.



If the camera app opens, follow the steps below:

• Press “Windows key + C” from your keyboard to open “Charms bar”.
• Select “Settings” option.
• Select “Permissions” option.
• Turn on “Allow this app to access your: Webcam and Microphone” option.
• Lose the app by pressing “Alt key + F4” from your keyboard.
• Reopen the Camera app.
• Connect your camera and then check how this app works.

Goodluck!
