The Zoom-In Mic is a feature first introduced on Galaxy Note10 and Note10+,
taking video and sound recording to a new level.
With the Zoom-In Mic on Galaxy S20, S20+, and S20 Ultra,
you can use a pinch gesture on the screen while recording video to zoom in or out,
and as you zoom in, the sounds of the subject you zoom in on become louder.
Zoom out, and the surrounding sound is no longer suppressed.
To use it, you don't need a separate app.
*Disclaimer: This feature is only available for the S and Note series (Note 10 series onward).
