The phones this year aren’t much tougher, but the Z Fold 4 and Z Flip 4 are still engineering marvels. We saw the foldable assembly line last year, and now that the new Flip and Fold are available, Samsung is giving us another look at how the sausage is made. And it’s really, really cool.
The video, which was discovered by XDA Developers, focuses primarily on the Fold 4, beginning with the moment its back cover is pressed into place and concluding with a look at the folding phone dunk tank.
Various functions, such as its response to the S Pen and wireless connectivity, are tested along the way. It passes a camera autofocus test by bringing a grid of white lights into focus, and another robot repeatedly presses its side keys — quite rude, in fact.

It’s one thing to get a passing grade on the assembly line, but it’s quite another to withstand multiple years of daily use in the hands of a real, live human.
If you’re picking up a Z Flip 4 or Z Fold 4 today, you might want to consider adding the Samsung Care Plus plan to your cart as well.
