The iPhone 13 and 14 cases are not universal. Although they may look similar in size and design, their enclosures are not universal due to differences in camera and button layout, motor and antenna positions, and so on, for each phone. In addition, there are slight differences in the size of the iPhone 13 and 14, which also cause their cases to be incompatible. Therefore, it is recommended that users choose a product specifically suitable for their own mobile phone model when purchasing the case to ensure that the mobile phone can be well protected and the use of experience.
