The physical dimensions and camera layouts of different iPhone models often vary significantly. Therefore, protective accessories designed for one model are generally not compatible with another. Cases are specifically engineered to conform to the precise contours of a particular device, including button placement, port openings, and camera module size.
Utilizing a case intended for a different iPhone model can lead to several complications. These may include obstructed access to buttons or ports, compromised camera functionality due to misaligned openings, and an inadequate level of protection as the case may not properly secure the device. Attempting to force a mismatched case onto a phone could potentially damage the phone itself.
