In a mobile device, There can't be a large camera sensor or lens. That's why we want to use separate cameras for our needs.
For a good picture combination we want a main camera with higher mega pixel ratings for to take a big picture and a depth camera for a real depth image or for a best focused image and a macro camera if you want to get some close pictures and a periscopic camera if you want to take a best zoomed picture and Tof camera if you want to take a 3D styled picture and an infrared camera if you want to get pictures in dark. ✌️😎
