Well this phone is nothing but the old J7 phone with Exynos 7870 chip set, and there is nothing to complain about. Using it for last 2 months, lag free performance, no heating issues, less battery consumption are some of key benefits I am experiencing till now!(Go for processors with semiconductor size of 14nm or less, it works!) Amoled screen with lower resolution is helping farther to last the battery charges longer.
Build quality at best is average, and the side panels are not matt finished as it seems from the picture, they are glossy and finishing is same as the first generation J7! Those panels are plastics not metal.! thanking you.
