Questions
Why is the picture black?
Another app may be using the camera (video calls often hold it), a privacy shutter or switch may be closed, or access may be blocked in your system privacy settings.
Why is the resolution lower than advertised?
Browsers start with a default size. Choose a higher resolution — the camera reports what it actually delivers, which also depends on light and USB bandwidth.
Are snapshots uploaded?
No. The snapshot is created in your browser and only saved if you download it.
