With foldable smartphones becoming increasingly popular and somewhat affordable these days, one of the biggest fears that people have is how long the hinge and the folded area of the screen will last before it gives up.
Over the years, smartphone manufacturers like Samsung have redesigned and refined the design of their hinges to the point where they are highly durable. Even the foldable screens that most smartphone brands source from Samsung have increased exponentially in quality and endurance.
To showcase just how durable their latest foldable devices, The Galaxy Flip 4 and the Galaxy Fold 4, are, Samsung shared a video showing some of the tests they have undergone before being deemed fit for release.
The short 100-second clip reveals all the rigorous tests that the foldable go through, including multiple button pressing, folding and unfolding, and testing their water resistance:
Reliability is critical for Samsung, as the company revealed in a press release, and it does all the testing to ensure the phones “can withstand everyday wear-and-tear” and meet the need of users. All the processes are automated, which is hardly a surprise, but the engineering behind developing these rigs is a marvel to watch.
The phone’s back panel is applied by one set of machines and then pressed firmly by another. Then the device is onto the functional testing to ensure the screen works with S Pen; the Samsung Pay service is okay, touch and proximity sensors, and the wireless coil also needs to go through the process.
We also see the water resistance test with multiple valves, spraying water on the foldable from all angles.
