I bought this camera for work and I am also using it on a camera stand.
I am filming a single person, standing still talking to the screen, with almost no movement and upon playback of the video, all you can see is a constant refocus "jump" at least once every 4 -5 seconds and sometimes even more.
I filmed all day and now these videos are all unusable. Yes, I saw there was some kind of "focus issue" with a relevant phone update. I got that update a couple days ago. As a matter of fact, I didn't even notice this problem until AFTER the update, so I am not sure what was actually fixed.
Am I going to have to return this phone? I DONT WANT TO!!!!
I apologize for the issue. I know it can be frustrating. Good news is that you're not the only one that this has happened to, Samsung is putting out an update for this exact issue, at a later time.
