Watch Samsung put its new folding phones through the ringer

Samsung is giving us a behind-the-scenes look at durability tests for its Z Fold 4 and Z Flip 4, including water resistance and fold durability.

If you needed any more convincing to switch to a foldable smartphone, Samsung is hoping to persuade us with a behind-the-scenes look at all the testing that goes into making its latest foldables, first spotted by XDA Developers.

Samsung’s video mostly revolves around the Galaxy Z Fold 4, but we get a glimpse of the Galaxy Z Flip 4 in the water resistance test. Both of the foldables have an IPX8 rating, but blasting them with water jets and dunking them into water gives us a lot more confidence about the water resistance.

Along with testing the water resistance, Samsung’s robots put the foldables through a series of additional tests, including wireless charging, folding durability, and key pressing.

It’s always cool to see how the sausage gets made, but it’s particularly interesting with a niche product like a foldable smartphone.

Real-world comparison

Samsung’s robo-testing of its smartphones seems pretty comprehensive, but how does it compare to the daily abuse that we may put it through? You can’t forget about human error, like bending the phone awkwardly or dropping it straight onto concrete.

For that, we do have some informal testing with the durability of the previous Z Flip 3. Polish YouTuber Mrkeybrd hit 418,500 folds in “The Great Folding Test” before the clamshell foldable couldn’t fully open or close. Although unofficial, it’s far more than the 200,000 folds that Samsung lists.

The Z Fold 4 and Z Flip 4 aren’t a major upgrade from its predecessors, but it’s nice knowing Samsung is maintaining that same level of quality testing. Plus, it’s always fun to see how it’s made.
