It is reported that on July 27, 2018, Beijing Millet Company applied to WIPO for a design patent describing a smartphone equipped with solar cell components. Seven sketches show a smartphone. The front panel is almost entirely made up of screens. It's not clear where the self-timer camera is. It doesn't seem to describe the camera, nor does it have a pop-up camera. It's likely that it will have a camera under the screen. The technology under development is recently developed by Millet. Show in a short demo video.
The back of the phone has a set of two vertical cameras, with a flash in the middle and no fingerprint identifier on the back, so it may be integrated behind the screen. The most striking of all is the solar panels, which cover most of the back cover. The whole machine does not seem to be getting thicker. The camera module stands out further than the solar panels. The integration of solar panels enables users to use solar energy to charge millet smartphones.
Whether Millet will actually launch this climate-friendly smartphone is unknown, but more companies have tried the possibility of solar smartphones before. For example, last year Caviar, a Russian manufacturer, released the back cover of the iPhone X Tesla, which has built-in solar cells. (Source: lets godigital)
