The primary sensor is equipped with the capability to put together four pixels into one neatly. All the four cameras work together to produce a crisp output. On the front, the Galaxy A9 (2018) is adorned with a 24MP selfie camera with f/2.0 aperture and support for Face Unlock functionality. The Galaxy A9 (2018) is claimed by Samsung to recognize 19 different scenes and enhance color setting to deliver shots according to the content.
