The average consumer likes a bigger screen, but I get a (truthy) feeling that production doesn't match demand. - Smartphone design goals are to cram as much into a phone as possible, so engineers prefer having more space to work with. - If I'm a designer for a smartphone, I'm probably pushing for more screen real estate to work with - If you can only pick 2-3 form factors to build with massive economies of scale (as Apple in particular has to do), the demand for a smaller screen might not align with the relative cost to produce - I wouldn't be surprised if the "it's smaller so it should be cheaper" mindset that people have in other markets (cars come to mind) plays a factor here. The reverse would be true true: A company can charge more for a bigger phone because it's bigger. So if, say, 20% of the market wants a smaller screen size but wants it done cheaply, there might not be enough incentives to mass-produce such a device in a way that makes enough money to be worth it.
