With today’s announcement of the Galaxy A7, Samsung now offers three mid to high-end devices with a metal unibody design. Even though the Galaxy A3, A5 and A7 sport the same slim unibody design, they pack greatly different specs under the hood. Below is a quick comparison of the tech specs of these handsets to clear up the confusion. The Galaxy A7 is currently the best smartphone in Samsung’s Galaxy A line-up, but the company is yet to reveal its launch date and price. On the other hand, the Galaxy A3 and A5 are already available in most major markets of the world, including the United States.
