In all fairness, I don't know it is accurate to say that people don't want a 4" phone because no one makes an up to date phone. And why would they? I am certain the margins on much higher on the XR, XS, and XS Max because they can up the cost to the customer more than the increase to their own cost. Same thing is happening in the car industry. Sedans and wagons are out because car companies are pushing people to the more profitable truck and CUV/SUV categories. Can't buy the low margin phone or car if it does not exist.
