I always see concept videos and rumors, in which iPhone 8 will not have a physical home button and that the screen will cover the entire front, thus the home button will be integrated into the screen. The question that keeps bugging me is how will it work? How would I watch a YouTube video or play a game? Would there always be a black portion of the screen with a round virtual home button or just a transparent circle on the screen? I highly doubt that Apple will do it, waste the space for the home button. Then, the question is - How would it work? No one can't come up with the solution and the detailed explanation of how would Apple make it work? They would never waste the screen space like Android does. During the iPhone presentation, Apple will most likely present the easy and simple way of having a virtual button, yet none of 7 billion people can figure out what it would be like. How do you think Home Button will work then?
