OnePlus Concept One: looks like it's not foldable
OnePlus has already confirmed that it will reveal its first-ever concept phone at CES this year. Now, it has offered further hints as to how this device, the Concept One, will look. They suggest that there is no flexible display at work here, as you may expect in a post-Galaxy Fold world. However, the OEM has integrated a different kind of tweak into its "alternate design".
A video posted to Twitter and on the OnePlus community website by the company's CEO, Pete Lau, indicates that the Concept One was built to show how a phone made with electrochromic glass would look and work. This material, also found in high-end cars such as the McLaren 720s, changes in color in response to an electric field acting on it. Here, it is used to "cloak" the device's triple rear cameras when they are not in use.
These main lenses are also located under the panel in question, rather than placed in the raised modules we have all become numb to at this stage. Then again, looking at a drawing also shared online, it is possible that the top half of the phone is thicker than the bottom so as to accomodate this novel camera-window arrangement.
It also shows that the Concept One's rear electrochromic glass runs all the way down the phone, tapering toward the bottom. Otherwise, the device appears to retain its maker's signature Alert Slider and to have physical buttons. It will be detailed in full at OnePlus' CES 2020 event located in the Wynn Hotel, Las Vegas.
