this was incredibly helpful, thanks.
my pleasure
How come it doesn't have the rings at the camera cutout as seen here??

also, how is the workmanship of the case?
It looks as if the edges are rigid/sharp to me... (from the photos)
It actually does have the black ring around the camera lens, the problem is that the black matches the phone's black so well you just can't see it. My ring has not fallen off (like others have pointed out)
The edges of the case are not sharp on any of the corners (even though they look that way) however the inside cutout of the volume buttons is super sharp. Wonder why that's the only place?
Does the case improve the grip of the phone? I find that a naked phone is slippery for me. Thanks.
to be honest, the clear version can get pretty slippery too. There's definitely no grip to it, if that's what you're asking.
