I'm trying to film myself in a dark room with videos. When I start the camera, it records as expected: it checks focus and stops on a nice and crisp view.
However, as I record every second or so, even if nothing changes, it runs the auto-focus feature. That means the video "jumps" (zoom in/out for a little while). It's very visible on the final video.
Is there a way for me to setup the camera so that it doesn't re-auto-focus all the time?
My phone is a Galaxy J7 (SM-J700T).
I've seen many options to change the lighting, colors, etc. but I don't recall seeing anything about auto-focus. I'm hoping I may have missed something so I can use the phone camera without having that bad side effect.
