All this changed though with the Galaxy S6 and the S6 Edge, ushering in a svelte metal and glass design that stunned many. From the days of the ungainly and bulky Galaxy S5, Samsung had transformed it’s ugly duckling into a beautiful swan with the Galaxy S6.CameraThe Samsung Galaxy J7 comes with a 13MP, rear camera with autofocus and LED flash and a 5MP front camera with a LED flash. Both the cameras have an aperture of f/1.9.The rear camera is above average and is actually one of the better shooters in this segment. In well lit situations, it produces sharp and vibrant images with vivid colors and deep blacks. The camera is very quick to focus and produces little or no lag when processing images as well.
