Samsung likes to make a big deal about its phone testing, especially after the explosive Galaxy Note 7 battery debacle.
It even employed a robot arse back in the day, just to see the effect an arse might have on its phones.
Now it's released a video of the Galaxy Fold's folding mechanism being stress tested, and it's a pretty mesmerising site.
Here's a looping GIF for you to enjoy as well:
Officially nobody has been able to get their hands on the Galaxy Fold to test the folding mechanism for themselves, though some have made their way into the world to show off a pretty big crease.
But Samsung has maintained that the phone will survive 200,000 folds before breaking, which amounts to 100 folds a day for five years.
