The Samsung Galaxy A9 is the world's first smartphone with no less than 4 cameras on the back. One of them is a 2x optical zoom camera to take pictures from a distance. Next is a wide-angle lens to capture all your friends or your whole family in one picture. Then there's the depth-of-field lens, and finally the main lens. This one has 24 megapixels and an f/1.7 aperture, so you can even make clear pictures in low light. On top of that, the camera is smart, thanks to AI Scene Recognition. This software recognizes when you're at a concert, for example, and automatically chooses the best settings for you. View all your pictures on the large 6.3-inch Full HD+ Super AMOLED screen.
