I'd return and replace it then. Probably some duds out there. My Baltic Blue one is nice and tight and doesn't pop out at any corners (or creak or anything). One of my kids knocked my phone off the couch yesterday onto the hardwood floor (face down) and it didn't pop out or loosen up at all.Received a California poppy leather just now. It looks pretty good. The cutout around the camera hole has that slight gap, it doesn’t necessarily look bad but the one I got has no gap near the top and gap all around the rest of the camera so it looks off. The buttons feel amazing.
The biggest issue is that it does not hold the phone in well at all. I am 100% certain that a drop on the face of the phone will destroy the phone as it pops out so easily. To test this I dropped the phone on it’s face from a height of one inch on to a hard mouse on. Sure enough, the phone popped out and the screen struck the mouse pad.
My silicon case had a simile issue, but the leather one is much much worse. Any drop is going to dislodge the phone from the case. Will probably try to get another one to see if i can get one that holds my phone in and doesn’t have the uneven gap around the camera.
I definitely experienced some creaking and stuff along the edges with some prior year Apple leather cases though. So I don't think it is new to this year's crop - just normal QA issues.
