Full HD display instead Quad HD. Eventhough features are good I prefer only quad HD panel. It does have LED flash also.
It also has Gyroscope. Go for C9 as the ram is higher. Remember today app eat more ram. I have 3gb ram mobile.
Samsung C9 Pro is better than huawei mate 8. It looks like OPPO F1S. I Really like this Phone .
Fault:
It comes with the greek language. However, you should install a keyboard for typing.
