This new samsung J7 is really a beautiful and powerful device. it has superior voice quality good enough(on call) loud enough(for music). The phone build seems to be superb, even better than before. looks have drastically improved. Super stylish sleek design. Nice to hold and touch. Screen colour looks punchy and vibrant. I got more than a day of battery backup on the first day of use. so far so good. Performance of mobile is very smart and so fast as expected. I like the cameras both back and front cameras are outstanding. No heating issues even after hours gaming and browsing. Less pre-installed apps that does not eat up the battery life. so if you want mobile from a reputed brand and overall a good performance(specially for gaming) just buy it.
