The Mate X3 features a book-like design that is similar to the Mate X2 and the Galaxy Z Fold series. It comes equipped with a 7.85-inch internal folding screen that boasts a resolution of 2,496 × 2,224 and a refresh rate of 120Hz, as well as a 6.4-inch FHD+ curved smartphone display with a refresh rate of 120Hz. Although the folding screen does not have ultra-thin glass protection, Huawei claims that it has a durable design that can withstand impacts.
