So what exactly does RAM do? Simply put, it helps in multi-tasking, i.e. moving from one application to another seamlessly. The heaviest applications are games. So in the test two of the most popular flagship devices from Samsung - the Note Edge and the Galaxy S6 Edge along with Zenfone 2 were made to run one heavy game after another without removing them from the multi-tasking tray until the phone itself force-closed it. The result was quite surprising.
