Can I access the device camera for testing?

The camera is accessible in Live and App Live for mobile devices, but not accessible on desktop platforms (Windows, MacOS) on Live. However, accessing the camera would only show a black feed. 

If your website has features, such as check scanning, profile image capture, and QR/Barcode scanning, you can use the Image Injection feature to test this on your website on select devices & browsers (Android devices + Chrome on Live & App Live and MacOS + Chrome on Live).
