As I mentioned in tittle it is the new mobile from the family of Samsung. It has come with unibody metal design . It comes in gold , silver and black . But there is slightly change in the display of the phone now it comes with TFT display but previous version is comes with amoled display which is far better than TFT display . There is no change in front of the phone which is similar like previous one .bt huge change in back of the phone now it comes with metal back which look far better than plastic . Bt there is no change in internal functions .so according to me it is better than previous one so go for it
