Samsung produces some of the most durable and functional foldable smartphones available. And a lot goes into creating these works of engineering genius. The freshly announced Galaxy Z Fold 4 and Galaxy Z Flip 4 are seen in a film from the Korean business that shows how they move through the manufacturing process before being handed to customers.

In the video, Samsung can be seen rigorously testing the foldable pair’s functionality and durability after they have been placed together. It starts with what seems to be the last stage of assembly: applying the back cover. Robots precisely position the back cover on top of the phone and compress it tightly once every component has been assembled. The system is now prepared to move on to the testing phase.

Functional testing is where Samsung begins. The touch and proximity sensors, S Pen (only on the Galaxy Z Fold 4), and Samsung Pay functionalities are all tested. Robotic arms are used for all tasks. The next step is network testing, during which Samsung determines whether the foldable’s network transmission and reception performance is up to par.

Samsung tests a variety of camera capabilities and operations during this process, including autofocus, zooming, image quality, and more. One of the distinguishing aspects of flagship devices is wireless charging, and Samsung provides it with both the Galaxy Z Fold 4 and Galaxy Z Flip 4. The business uses a wireless charging coil to assess the phones’ capabilities.

Samsung then puts its excellent Flex Mode function to the test, which allows you to utilize foldables at different angles without fully unfolding them. Both halves of the screen are available for use for various things.

FOLD 4 AND FLIP 4 OF THE GALAXY Z ARE WATER-RESISTANT. The sole manufacturer of water-resistant foldables is still Samsung. The Galaxy Z Fold 4 and Galaxy Z Flip 4 have a certified water resistance certification of IPX8. No other company has developed a method for preventing water from entering its foldable devices. This video demonstrates the various methods involved in evaluating the phones’ water resistance.

The Galaxy Z Fold 4 and Galaxy Z Flip 4 are also put through a lengthy, rapid-fire folding test in which robots fold and unfold the tablet. Samsung also uses robotic arms to continually push the physical keys in order to test them. Be aware that using the phones in the real world is very different from the rigorous durability and functional testing that the new Samsung foldables have undergone in this video. Nevertheless, you should use the gadgets with caution.
