Before the D3400, you chose your smartphone camera for convenience. Zooming was clumsy. Shooting in low light was nearly impossible. Capturing fast action was a game of luck. But after the D3400, you'll see that you were compromising image quality. That some of the greatest photos happen when the light is low. That fast action can be frozen in perfect clarity. And that a camera and a smartphone can work together in harmony to make the photos you share absolutely amazing.
