Will an old phone case fit a new phone?

Use dimensions as a filter, not proof. Camera islands, buttons, speakers and corner geometry can break case compatibility.

Dimensions are necessary, not sufficient

A rigid phone case has to align with the entire exterior shape. Two phones can publish the same height, width and depth and still use different camera openings, control locations, microphones or speaker cutouts.

A safe case-fit checklist

1. Compare exact height, width and depth.
2. Check the camera module footprint and location.
3. Check side-button and control openings.
4. Check speaker, microphone and USB-C openings.
5. Prefer an accessory listing that names the exact new phone model.
