OnePlus will introduce its first concept phone -- the imaginatively named OnePlus Concept One -- when kicks off next week. But on Friday, the company hinted at what to expect. China-based OnePlus tweeted a 10-second preview of the device's "invisible camera" and "color-shifting glass technology."
The effect is achieved using electrochromic glass, which changes from transparent to translucent when electrical current is applied. It hides the rear camera lenses behind a clean glass body, showing them only when they're in use, the company said in a release.
Such glass is used to reduce glare in the windows ofand , OnePlus noted. OnePlus released a of its OnePlus 7T Pro last year.
OnePlus previously noted that Concept One would be the first in a new series and would bring an "ever smoother, faster, and more 'burdenless' experience."
