iPhone camera black - no picture

Your iPhone's camera doesn't show an image, it just shows black?

Here I describe what you can do if the camera image is black.

If the camera lens is not simply dirty or covered, you can usually reactivate the camera using the following tips:

1. Turn your iPhone off completely and then turn it back on. Now test whether the camera works again.
2. Go to Settings. Open the General menu and tap Restrictions. Check the camera point - if necessary, deactivate and activate it once.
3. Make sure no other apps are accessing the camera - close other apps.
4. Perform a soft reset on the iPhone -> Press and quickly release the volume up button. Press and quickly release the volume down button. Press and hold the side button. Release the side button when the Apple logo appears.
5. Attempt to install available updates.
