What is the blue icon on the top of my homescreen?

On my s10 plus there is a blue on top of the homescreen with a speaker icon on it but volume keys don't move it. What is it for and how do I get rid of it?

Is that the volume slider on screen? You may have to turn that option off

Taken care of. Thanks all

It means your microphone is on. Have you done anything you shouldn't of.
