OnePlus teases 'special project' with cryptic photo and video

OnePlus is cooking something up, but we can't exactly say what that is if we base it on the company's latest teaser. A tweet on the OnePlus UK account states, "We're working on something really cool and we really can't tell you yet. To be continued." Rumours about the upcoming OnePlus 8 have already started surfacing, so it's logical to think it's related to that. Some of the recent speculations suggest one of the phones in the series will come with wireless charging, while all three units will feature hole-punch displays. But we can't exactly say how the image relates to that. Some people on Twitter are speculating the company might be working on a foldable device or power bank. 

But then, the company also tweeted recently that it's working on a "special project" that isn't a phone or commercial product. And then showed off a quick clip a few hours ago showing off the mystery project and the words "Making progress." The date 03.03.2020 was also seen at the end of the clip. What's your guess? What do you think OnePlus is cooking up?
