Honestly, I never thought that I'd be defending facebook, but I honestly think its a bug. It always takes some time until the camera is initialized and the first frame rendered on the canvas. I bet the Instagram app, Snapchat, Twitter and WhatsApp are doing the same thing. I honestly think it is a feature to improve the user experience when starting the camera. That being said, while they are already using the camera, they'd probably be able to do some on device ML to detect faces, emotions etc. But I'm pretty confident they're not constantly streaming your private camera feed.
