The concept of a modular smartphone was first made public when Dutch designer, Dave Hakkens, introduced the world to an idea called Phonebloks. Shortly after this video went viral, Google announced a partnership with the concept's originator and the two planned to work hand in hand on a real life execution of the idea dubbed ‘Project Ara'.
