What does the Flower looking slider do on the Go App?

[Capt Drone]

My Mavic just came back from the shop with new software. There is now a slider next to the camera tilt indicator. There is a flower icon on the top of it. I touched it in flight and everything went blury. Can't get it back in focus. What is this supposed to do? Thanks guys!

You've got it in manual focus, and that's the focus scale where you manually set the focal distance.

Near the top of the screen is a button AF/MF which you can tap to switch back to autofocus.
