Smartphones, in general, have evolved greatly over the course of past few years, with the recent of them seeing the most significant, defining moments in the mobile device technology. With its Retina display introduced in iPhone 4, Apple started a feud that particularly focused on higher resolution screens with remarkably deep blacks and crazy contrast ratios. The trend didn’t stop there, either, as certain manufacturers continued to raise the bar in the pixel density arena even if the Cupertino giant never took it above a certain level. These days, several high-end Android smartphones are boasting a true HD, 1080p screen packed in just about 5” of diagonal real estate, giving the crispiest displays that we’d ever dreamed of, to date.
