Camera lens cracked?

This morning I went to take a photo and found out that my camera lens was completely shattered. I have honestly no idea how it happened. I got it repaired no big deal, but I am curious how many people have had this/heard of this happening?

Do you have a case on it? If not the camera could have hit a table when laying it down and caused the issue.

Yep, I have an otterbox. It did fall yesterday and I didn't think anything of it because it fell on a corner, but maybe the impact was more than I thought.
