In skydiving, it isn't unheard of for someone to have their phone fall out of their pocket and survive impact without the screen shattering. That's from ~13000ft, but once the phone reaches terminal velocity, it's all the same impact force regardless of altitude.
I think dirt/grass is just a lot softer than the things we usually drop our phones over, like concrete or tile.
