The compatibility of protective shells between different iPhone models is a common concern for consumers. The design and dimensions of each iPhone generation often vary, potentially impacting whether accessories created for one model will properly fit another.
The primary factors influencing case compatibility are the device’s size, camera bump dimensions and location, button placement, and port locations. Subtle differences in these aspects can render a case designed for one model unusable on another. Historically, even minor alterations in design have resulted in incompatibility.
