Earlier quoted context omitted.
Around 2005 digital cameras were commonplace. Mobile phones also had cameras by then, even if not very good ones by today's standards. Maybe you're talking about an earlier time?
2005 is pre iPhone. While cameras were definitely common, they also weren't quiet as ubiquitous as they're today. Lots of families only had them for trips etc, not readily available for kids to make photos of screens.
I hate how incompetent tech writing and marketing rewrote and simplified mobile phone history into pre/post-iphone. Yes, we did have touchscreens, smartphones and camera-enabled devices many years before the iPhone. Arguably, on several metrics, many Symbian/Linux/blackberry phones of that era are better smartphones than today's iPhone/Androids as defined by hardware capabilities which got removed over time while arbitrary constraints got added on the software front.
