Case for iPhone 14

I use a Zagg case on my iPhone and the case doesn't show the frame of the iPhone on my iPhone. Some cases are minimal and some are less so. If you have a BestBuy Store near you, you could go there and try some of their cases on your phone to see if one meets your expectations. Same at an Apple Store, where they sell loads of cases for their iPhones.

I'm not sure I fully understand your question? A typical iPhone case will cover the case on all four sides and the back of the iPhone, with an opening for the camera module.
