This section covers the phone’s overall build materials, construction, finish, and even color options. Like fashion, new launches bring fresh, creatively named colors whose final look depends on materials such as aluminum, glass, or ceramic. Each material has pros and cons: for example, glass can boost signal and wireless charging, but may be more fragile, so many brands use Corning Gorilla Glass for added screen protection. A phone’s resistance to dust and water is defined by its official IP rating, giving you a clear idea of how durable it really is.
