Pros-
1 No lagging problems.
2 Camera quality is good.
3 Slim metal body makes it look cool.
Cons-
1 Sometimes the phone overheats.
2 Batter life is not so good.
3 Some new features are absent. ( OTG support, Fingerprint sensor)
4 Cost is too high.
Frankly speaking, the main issue is its cost. Most of the new smartphones cost much less and offer many more features. But the best part about a samsung phone is its service. They offer us 100% customer satisfaction. Also check Lenovo k4 note, Xiomi MI note4 , Moto G X play.
