Another big achievement of samsung . its a very good phone with 3 gigabytes of RAM, quad HD display, 2550 mah battey , with lollipop 5.1.1 . it has a exynos 7420 processor . it has 16 meaga pixel of back camea and at front it has 5 mega pixel . in terms of battery life I wouls say its not good , the battery in this drains so much fast, so if u want this a bigger battery life then don’t buy this phone. this phone is very good in terms of heavy gaming . I have played heavy games like asphalt 8, fifa 16, need for speed, nova 3 etc, but I don’t feel any lag on it ., so I would say its very good in terms of heavy gaming .its UI is also good . it has a ir sensor which good as compared to the early phone samsung . the thing which I don’t like is that it is not a waterproof phone . this phone has a metallic body with back glass . it has heart sensor which tells your heart rate. overall we can say that it is very good phone by samsung and it is better than iphone 6 .
