The point is that its on top of the thing it replaced (keyboard). It doesn't matter much if its 10 minutes or 30 minutes, its an unnecessary waste in both situations.

I don't, but if I mostly type and scroll on the bottom, the fingerprints are mostly on the keyboard part. So I tend to read the top and maybe mid of my screen and then scroll further.

I actually preferred the time with hardware keyboards for example because screen stayed pristine back then, and phones were much more durable. Alas, those phones are exceptions, and if you also have other special interests such as long-term support, high uptime on one juice load, or the liberty to e.g. run SailfishOS your options quickly diminish. So my smartphone does not have a hardware keyboard, but that does not mean I don't prefer that. Choosing a smartphone is a matter of concessions. Choosing a MBP, idem.

Finally, given how often people are replacing their smartphones, I'm not exactly sure if "people cope with their smartphone" in general.
