The 16MP Ultra Wide Camera is part of the pro-grade camera system on Galaxy S10 series phones and Galaxy Fold. With a 123 degree field of vision, it expands your view in a significant way, seeing almost as much as your eyes can — much wider than the Wide-angle Camera does. So when you want to capture more of the scene all at once with your smartphone camera, the Ultra Wide Camera on your Galaxy phone is able to fit it all in frame.
To take a photo with the Ultra Wide Camera, simply open the Camera app and use the three icons near the bottom of the viewfinder to toggle between the pro-grade Ultra Wide, Wide-angle, and Telephoto Cameras.
