I have a permanent impression in my screen protector that resulted from some tiny pointed object pressing against it when it was in my bag on the trip back from Thailand. I have no idea what it would have done if it had been directly on the glass.
It would have been fine. Because Glass is harder than steel, whereas the screen protector is just a piece of plastic that scratches easily.
The only reason people buy screen protectors for glass screens is because of a lack of understanding of basic physics. Take a knife to your screen protector - it will cut through like butter. Try hard as you can to scratch your glass mobile phone screen (erm - don't try this on nokias or phones with plastic screens, obviously
The GorillaGlass they use on the iPhone and also high end Samsungs is hardened even more - don't know the details but I am sure a quick Google search would fill you in.
My wife recently came to me "Honey, I scratched my iPhone screen". She was sad. I took a look, took off the screen protector, and handed it back scratch-free.
The only thing you have to be careful about is sand and stones, concrete - that can sometimes scratch a screen, I guess it depends on the exact material in the sand/stone/concrete. In any case, I am not trying it out. Steel is fine though.
On my screen, it's not just a regular plastic screen protector, it's one of those ones that's the same material used for invisible car paint shields. They do not scratch easily. In fact the way they go bad is the edges start peeling up and dirt gets under and they yellow, not that the material scratches. Invisibleshield is one brand. There are Youtube videos on them. I use Bodyguardz since the material is a little clearer and they give you two full body protectors in a package for the same price. Anyway, also in that Korean video they drop the phone from waist high and it was ok, but then again from head high at which point the screen cracks. My worry was not that my screen would have scratched, but that the point pressure would have cracked the screen. But with the protectors, front and back, there was a little cushioning. They're kinda spongy. If I press a metal pointy object into it, the impression will show, then slowly recover to where you can't see it anymore in about 10 seconds.
