Samsung showed the process of assembling its most advanced smartphones – Galaxy Z Fold4

In automatic mode

Samsung decided to show how its most modern smartphones are assembled. We are, of course, talking about the foldable Galaxy Z Fold4. 

Assembly is done automatically by robots, although it cannot be said for sure that there is not a single manual process, it’s just that Samsung could not include them in the video.  

There are also tests on the video that the devices are subjected to at the factory. This includes testing the screen for bending, and testing water protection. There is also a robot that tests the side buttons.
