Samsung is the leading mobile brand all over the world but this perticular Galaxy J7 Prime model is way too overprice. The camera and the battery life is quite empressive part of the phone it costs ypu nearly 19000 and they give you 3GB of Ram which is also good but they provide 1.6 Ghz octacire processor in the mobile which is apparently is the bottleneck for this phone. On the other hand you get Lenovo z2 with 3GB Ram and snapdragon 820 which is the second best prosessor in the android market so if you are not a camera guy then you should buy Lenovo Z2
