Phones in the same family can look identical but have cameras and buttons in different places, so a case that fits one may not fit its sibling. A two-minute check saves you a return. Here is how to be sure.
Find Your Exact Model
Do not rely on the marketing name alone. Go to Settings, then About, to see the precise model (for example iPhone 15 versus 15 Plus, or Galaxy S24 versus S24 Plus versus Ultra). On the box or under the battery you will also find a model number. Base, Plus, Pro, and Ultra versions of the same year are almost always different sizes and need their own case.
Match the Cutouts
Camera placement is the biggest fit issue. Even between generations, the camera island can move or grow, so a previous-year case often will not seal around the lenses. Check that the listing names your exact model and year. A precise-fit model-specific case lines up buttons, ports, and camera cutouts exactly. Shop by model in the cases collection.
When in Doubt, Buy by Model Page
The safest approach is to buy from a page dedicated to your exact model rather than a universal or multi-fit listing. Universal cases exist but rarely align cutouts perfectly.
Frequently Asked Questions
Will last year's case fit this year's phone? Usually not. Even small changes in size or camera position mean cases are generally not cross-compatible between generations. Always check the listed model and year.
Do Plus and Pro models share a case? Rarely. Within one year, the base, Plus, Pro, and Ultra sizes differ, so each needs its own case.
Where do I find my exact model? Settings, then About (or General, then About), shows the precise model name and number. The retail box lists it too.
Confirm the exact model, match the camera cutout, and buy from a model-specific page. That is how you avoid an ill-fitting case.
