The Galaxy J7’s 13-megapixel auto focus camera with f/1.9 aperture with single LED flash is average, but not the best. The camera UI is similar to other Samsung smartphones running Android Lollipop. It has several modes( Auto, Pro( lets you adjust white balance, ISO and exposure manually), Panorama, Continuous shot, Beauty face, Sound & shot, Sports and HDR.), Effects( Grey-scale, Sepia, Negative), and timer( 2, 5 or 10 seconds) . You can also press the home button twice to launch the camera, even when the screen is off and use the volume rockers as camera shutter.
Daylight shots are decent, but the exposure is not consistent, so most images end up dull or over exposed. Macro shots are good offering nice bokeh effect, thanks to f/1.9 aperture. Images are sharp and the color reproduction is good. HDR shots are better, again you face exposure issues in daylight. It is recommended to use the pro mode and adjust the exposure accordingly. Low-light shots have some noise as usual, but the images are not too bad. Images with flash are good since the flash offers an ample amount of light and is not over powering.
