I recommend The Image by Daniel Boorstin. Smart phone is not the dawn at all but I guess more like high noon. The world is replaced by graphics (more generally , images) for a century at least. Books by "digests", heroism by celebrity and so forth. A little bit of media theory goes a long way to making the world "legible" again. Since we are absolutely steeped in media culture.
Fahrenheit 451 didn't get as embedded into popular culture as 1984, but does a good job depicting a society brain rotted on reality TV and war propaganda.
"the world has been replaced by graphics (more generally, images)"
Humankind started to record its history by images (google for instance about the city of Sefar, Algeria). Nowadays, even in tech we use graphics (diagrams and so on)
This is not my field but even the first letter of the latin alphabet is simply the image of the head of a cow rotated a bit to the left.
