Huawei is about to unveil the first phone with a screen hole, trying to beat Samsung on this. The said phone is allegedly called Huawei nova 4, renders of which just hit the media.
The design of the back looks pretty much like a P20 Pro. The front features screen with a hole for the selfie camera in the top left corner. This matches the official teaser and the disguised device that was spotted in the wild.
Huawei even live streamed a demo of a prototype device with such a screen hole, which served as the basis of this render. Indeed, the presenters were very careful not to show the back during the stream.
Chances are that the Huawei nova 4 (as well as the Samsung phone) will used BOE-made LCDs, which explains the similarities in the display design and camera hole positioning.
