Huawei's Mate 30 and Mate 30 Pro smartphones, released in September 2019, sported AMOLED displays made by Samsung Display (rigid 6.62" 1080x2340) and BOE (flexible 6.53" 1176x2400, the Mate 30 Pro).
According to a report from Korea, Huawei will soon launch its next flagship phones, the Mate 40 and Mate 40 Pro - and the flexible OLEDs used in the Mate 40 Pro will be supplied by Samsung and LG Display (50% split). This is an interesting achievement by the Korean OLED makers and likely quite a blow for BOE. Apparently BOE could not match Huawei's requirement for this curved OLED display.
The Mate 30 family of smartphones (which also include a 5G edition of the Mate 30) features a graphene heat dissipation film, it is likely that the Mate 40 will also include such a graphene film. The Huawei Mate 30 and Mate 30 Pro are now shipping globally starting at around $650 for the Mate 30.
