We’ve all done it

If you hold it above your face, yes. But normal people hold it on their chest so the worst happening is the top of the phone slightly touching your chin when it slips out of your hand.

Having a phone grip is super useful to avoid this. So I don’t really drop my phone on my face, but I do drop my Kindle! Which is funny, because I read until I fall asleep but dropping the Kindle on my face very much wakes me up.
