The video shows Samsung putting the foldable duo through rigorous durability and functional testing procedure after assembling them. It begins with what appears to be the final step of the assembly process: putting on the back cover. Once all components are fitted, robots precisely place the back cover on top of the phone and compress it firmly. The device is now ready to enter the testing stage. Samsung begins with functional testing. It checks the device’s touch and proximity sensors, S Pen (only on the Galaxy Z Fold 4), and features like Samsung Pay. Everything is done using robotic arms. This step is followed by network testing where Samsung evaluates whether the performance of network transmission and reception of the foldable is up to the mark. The foldable smartphones then enter camera testing. During this process, Samsung checks camera functions and features such as autofocus, zooming, image resolution, and more. Wireless charging is one of the standout features of flagship products and Samsung offers that with both the Galaxy Z Fold 4 and Galaxy Z Flip 4. The company tests the performance by placing the phones on a wireless charging coil. Next up, Samsung tests the Flex Mode, an awesome feature that lets you use the foldables at various angles, without fully unfolding them. You can use either half of the screen for different purposes.
The Galaxy Z Fold 4 and Flip 4 are water-resistant
Samsung is still the only maker of water-resistant foldables. The Galaxy Z Fold 4 and Galaxy Z Flip 4 come with an official IPX8 rating for water resistance. No other brand has figured out a way to keep water out of their foldable products. This video shows the various steps of water-resistance testing the phones go through. Firstly, Samsung puts the devices in a water chamber. After that, the handsets are subject to high-speed water jets from multiple angles. The company also submerges them underwater for a prolonged duration while the screen is on. The Galaxy Z Fold 4 and Galaxy Z Flip 4 further go through a folding test where robots fold and unfold the device in quick succession, for quite a long. Samsung also tests the physical keys by repeatedly pressing them using robotic arms. While this video highlights the rigorous durability and functional testing of the new Samsung foldables, be mindful that using the phones in the real world is altogether different. You still need to be careful with the devices.
