The video shows parts of the Concept One smartphone, which has the classic OnePlus slider in a variant of the colour gold. The video also showed the front of the device having curved-edge glass-like in the OnePlus 7T Pro. It is unclear if the display is curved at the edges. The teaser video shows the rear side of the Concept One smartphone, which is marked with a OnePlus logo and a pattern. The teaser showed three cameras on the rear of the device with a flash at a particular angle. This might be the invisible camera feature on the device. The appearance of the invisible camera looks like in-display camera technology or cameras which function only when the camera feature is turned on. It is also possible that the invisibility feature of the camera works through a button. OnePlus might reveal more information or teasers as we edge closer to the CES 2020. The Concept One could possibly help us identify key features we can expect from the OnePlus 8 Pro and the OnePlus 8T Pro. There is no official information about the colour-shifting glass technology yet, but more will be known in the coming days.
