The Galaxy M20 does not offer a terrific set of cameras, but it does offer a lens that is unique to this segment - an ultra wide-angle camera. The M20 comes with a 13MP primary sensor on the back with f/1.9 aperture and a secondary 5MP ultra wide-angle sensor with f/2.2 aperture. With the secondary lens, you will be able to capture more area in a single frame. The camera app lets you switch between the standard field of view and an ultra wide field of view with a simple tap.
Photos captured through the rear camera in daylight look decent. Colours reproduction isn't great as photos often look washed out. In comparison, the Redmi Note 6 Pro tends to offer more detail and more accurate colours in similar lighting conditions. The M20's camera does not offer the best dynamic range, but it does come with a pretty fast shutter speed so photos rarely come out hazy.
