Samsung seems to be strengthening its metal-clad smartphone product line by launching on Monday the slimmest smartphone device called the Samsung Galaxy A7. 

The device comes after the unveiling of the premium metal-cased Samsung Galaxy A3 and Galaxy A5 handheld products in October 2014. This time, the Galaxy A7 features a bigger, thinner design compared to its predecessors. 

But aside from the slimmer feature, can the Galaxy A7 compete against the Galaxy A5, as well as the South Korean tech giant's flagship devices like the Samsung Galaxy Note 4 and the Samsung Galaxy S5? Here is the comparison of the four premium Samsung smartphone products:
