The phone was not unfolded. If it was a foldable one, it could have been any of the current ones in the market. The guy suspiciously holds it in such a way as to hide the thickness. So it could have been a setup with the help of a friend so this author could have something to write about a Pixel foldable phone.
Is this supposed to be satire? Maybe try taking the pictures with the camera next time instead of a Texas instruments calculator?
