If you remember, Huawei announced the Mate 9 Porsche Design along with the regular Mate 9. It used the same hardware except for the screen, which was AMOLED and a curved one at that. It was also prohibitively expensive, and it was only going to be sold through Porsche Design exclusive boutiques. It set off a gadget craving that the regular Mate 9 could not fulfill.
