I don’t know if I’d even call it a crack, it’s a tiny speck on the edge of the circle but it’s still super annoying. Doesn’t affect any images but the lenses aren’t as tough as I thought. If you don’t have a case that protects the camera well, I’d recommend one! I thought my case was strong enough but I guess not
It didn’t break or crack, and it still works fine? Sounds tough enough to me.
