My camera is zooming out

When anyone enters in the room, the camera automatically zooms out

I have the same issue, but it happens randomly even without anyone entering or exiting the room. Pretty annoying

I am glad I am not the only one having this issue. It is very annoying when you are streaming as well 

This is a setting possibly mobile phones only, or possibly just Zoom for android called "Auto Framing".  

To enable or disable this is very tricky.  
This setting is NOT on the menu (general or meetings) but only available when you are on a meeting and on Camera.  If you want to disable it, do it in a meeting, or launch a new meeting even with just you in it. Turn on your camera, or, click the ellipse (...) at the bottom right, and open "background and effects".

Look around the screen for a floating, semi-transparent, circular icon (sometimes blue) with a camera on it.

Click that icon, and you will see "Auto Framing".  Turn it off or on whenever you like.

This feature's placement accessiblity wasn't properly thought of.  They should have a menu item for both camera and audio settings.

I tried this but I do not see any floating camera icon.  

Most of these replies are wrong. Open settings in zoom and toggle the option to see video controls. There is a square icon that says center stage. Turn this off.

Months later and I still can't find an answer! None of the suggestions work, and I'm tired of my whole desk suddenly appearing in the view when the other person joins the call. I am on my HP laptop.
