Samsung's first foldable smartphone is due to go on sale next month, and the South Korean tech giant is furiously testing the new device ahead of release.
It has even gone as far as to build a robot to test whether the Galaxy Fold can outlast 200,000 folds and unfolds (or around five years of use, if used 100 times a day).
The South Korean smartphone maker has released a video of the test, which reportedly took a full week to complete.
The video shows the robot repeatedly folding and unfolding six Galaxy Fold phones, with close-up shots of the flexible display showing no visible crease.

"While the extent of the test may seem like overkill to some, Samsung viewed it as vital to ensuring the durability of device's hinged design and Infinity Flex Display," the company said in a statement.
Samsung had to develop new manufacturing processes for the phone's hinge, which has multiple interlocking gears to allow it to withstand being opened and closed hundreds of thousands of times.
The company has reportedly been working overtime to eliminate the crease down the middle of the display, where the phone folds.

"But what we do know is that the phones going to the end-users will have no crease whatsoever. Not even when the display is off, or all white."
