Isn’t the new fold the one that appears when the stock fold hinge seizes mid-fold due to dust intrusion? If so, that would be a logical outcome to plan for, what with dust being the mortal enemy of hinged displays and all, especially if the case design is well understood to respond to the eventually-certain hinge seizure event by introducing new folds into itself in one of those two locations. I wonder what one of the various battery X-ray people will find when they scan an unbroken one. Does it have cell safety dividers at the known auto-hinge points?

Especially when they advertise it with an IP68 dustproof rating.

his recent iphone tests endured this (more) and still worked.
