The Galaxy J7 has 5.5-inch super amoled display with a pixel resolution of 1280* 720 pixels ans a pixel density of around 267 PPI. The display is bright, has good viewing angles and the sunlight visibility is also good. Since it doesn’t have an ambient light sensor you have to adjust the brightness manually using the slider depending on the conditions.
Overall the build quality of the snartphone is good for the price.
