No, not all Samsung phone cases are the same size. Each Samsung phone model has its own unique dimensions, and cases are specifically designed to fit those dimensions. For example, a Samsung Galaxy S25 case will not fit a Samsung Galaxy S24 or any other model, as each phone has differences in size, shape, camera placement, and button locations.
It's important to choose a case that is designed for your specific Samsung phone model to ensure a perfect fit, proper functionality, and adequate protection.
Even cases for phones within the same series (e.g., Galaxy S series) will differ from model to model due to changes in design and specifications over the years. Always check the case compatibility to ensure it matches your phone model.
