The Samsung Galaxy Fold is an expensive and complicated kit, so we were fascinated and shocked to see someone disassemble it. Still, it sure is interesting to see what makes the phone "dial".
The hinge is a complicated mechanism that consists of five parts, whose purpose is to unfold the screen and keep it flat when the phone is open and fold it when the user closes it. The gears of the mechanism are reminiscent of a mechanical watch. This hinge has been redesigned repeatedly several times during the development process.
A close look at the Galaxy Fold hinge mechanism
The person who dismantled the Galaxy Fold and posted the pictures on the Weibo reports that the hinge depends on a very precise alignment (which greatly complicates the assembly process). If the components are misaligned, the hinge may damage the screen.
Samsung is investigating reports of screens that fail, it will be interesting to see if there are more problems beyond the protection that some have removed.
Either way, the large folding screen is fairly easy to remove, it is soft "like rubber". The small external screen is the one that caused problems, breaking during the disassembly.
The internal components of Samsung Galaxy Fold
The two halves of the Samsung Galaxy Fold are connected by a pair of ribbon cables. Interestingly, the two batteries come in different forms. It is not clear if their capabilities are identical, though (the label says "TBD mAh, TBD WH").
We are yet to see how much Samsung will charge for replacing any screen on your $ 1,980 phone. But if the price has not been clear, this is a device of early adoption.
