2022 phones aren't much more durable, but the Z Fold 4 and Z Flip 4 are still something of an engineering marvel.In
The video mainly shows the assembly of the Fold 4,from the moment its rear cover snaps into place to a glance at the collapsible phone tank. Along the way, various features are tested, such as the reaction to the S Pen and wireless connection. The device passes the camera's autofocus test by focusing on a grid of white lights while another robot repeatedly presses its side keys - quite rudely, actually.
Of course, it's nice to "look behind the scenes" of the assembly, butit's hard to say that this inspires confidence in the durability of the Z Fold or Z Flip. It's one thing to come off the assembly line with a passing grade, but quite another to endure several years of daily use in the hands of a real living person.
