Oppo, another Chinese brand, is reportedly sourcing curved panels from Samsung for its next flagship as well. In sale the device will arrive in late this year. Most phones are opting for a taller 18:9 aspect ratio now instead of the older 16:9 displays, which helps quite a bit for usability, and I'd expect Huawei to utilize all of this to make a phone that's actually still usable.
The Huawei Mate 20 may feature the largest screen size amongst high-end flagships.
As per a report, Huawei has placed an order with Samsung Displays for 6.9-inch AMOLED panels that are intended for devices to be launched in the fourth quarter of 2018 or in early 2019.
The Huawei Mate 20 Pro, as part of the Mate range, is always going to be a larger device, but you might be surprised by just how big.
It is pretty clear that smartphones with a large footprint are here to stay. The Mate 10 Pro is hardly a small phone with its 6-inch screen, but if the Mate 20 or whatever the sequel will be called increases this to almost 7 inches, it'll be larger than most other phones available today. We'll know more as 2018 progresses, and also discover whether Huawei is planning to use this screen on a Mate phone, or an entirely new line altogether. "Samsung's upcoming Galaxy Note9 is said to go with a 6.38" panel, and Apple's new big iPhone will have a 6.46" screen. One thing that is sure is that a 6.9-inch display will definitely be too huge on a smartphone. The last time we came across a leak about the Mate 20 was back in March this year.
That would make the Huawei Mate 20 Pro far bigger than the 6-inch Huawei Mate 10 Pro, and probably also much bigger than the Samsung Galaxy Note 9 and iPhone XI Plus, which are rumored to come in at around 6.3 inches and 6.5 inches respectively.
