In addition to the same camera configuration used by the Huawei P20 Pro (40 MP RGB, 20 MP monochrome, and 8 MP telephoto), the Porsche Design Huawei Mate RS features 256 GB or 512 GB internal storage, an in-display fingerprint reader, a curved 6-inch 2K touchscreen, and is the world's first microcapsule PCM-cooled handset. All these innovations also come with a price: more than US$2,000 for the 512 GB variant.
