Watch the Samsung Galaxy Z Fold 4 as it’s assembled and examined

Samsung made big strides with foldables last year in terms of durability — the Z Flip 3 and Z Fold 3 are the first devices in this series to offer serious water resistance and an IPX8 rating. This year’s phones aren’t much tougher, but the Z Fold 4 and Z Flip 4 are still engineering marvels. We got a glimpse of last year’s foldable assembly line, and when the new Flip and Fold went on sale today, Samsung gave us an idea of ​​how the sausage was made. And that’s really cool.

Video- found by XDA Developer — mostly featuring the Fold 4, starting from the moment the back cover is pushed into place and ending with the display of the foldable phone’s dunk tank. Along the way, various functions were tested, such as its responsiveness to the S Pen and wireless connectivity. It got the camera’s autofocus test by bringing a grid of white lights into focus, and another robot pressing its side button repeatedly—a bit rough, really.

It’s great to peek behind the curtain, but it’s hard to say that it inspires much confidence in the long-term durability of the Z Fold or Z Flip. Rolling it off the assembly line with passing grades is one thing, but it’s another thing entirely to endure several years of everyday use in the hands of real, living humans. If you bought the Z Flip 4 or Z Fold 4 today, it might be a good idea to add the Samsung Care Plus plan to your cart as well.
