"You're unboxing it wrong" (see Samsung speaks up about broken Galaxy Fold review units | Engadget)
"Samsung's futuristic Galaxy Fold is launching this month, and the device has already made its way to a select group of reviewers and influencers. During the run-up to the device's launch, there were concerns about the durability of the folding display, and now after just a few days with the public, the device is already experiencing problems. There are numerous reports of Samsung's $2,000 device breaking after a single day, sometimes due to poor durability, other times due to user error.Bendgate 2.0: Samsung’s $2,000 foldable phone is already breaking | Ars Technica
First up, we have a report from Dieter Bohn at The Verge, who had a piece of debris get under the Galaxy Fold display (possibly through the hinge?) and press up against the back of the display. In addition to causing an unsightly bump in the OLED panel, it eventually pressed against the display enough to break it, killing a few horizontal and vertical rows of pixels."
