Just a month ago, Samsung unveiled two of its most advanced phones, the Galaxy Z Flip 4 and Fold 4, and although they are equipped with a lot of advanced technology, foldable devices are still somewhat fragile devices. The idea is to keep them safe, away from sharp edges and other sharp objects, given their fragility compared to your regular glass-backed phones, but Samsung has pointed to improvements in durability over previous generations. Wondering how true that can be, YouTuber Zack Nelson known as JerryRigEverything subjected the Galaxy Z Flip 4 to exactly the kind of fire test we’d expect it to be.

Samsung has done its best to educate new foldable device owners about what to expect from their phone’s longevity, complete with plenty of software warnings: It clearly doesn’t want a repeat of the original Galaxy Fold, but for testing, Nelson remains and deliberately ignores all these warnings, in the interest of the consumer of course.

In a hardness test, the Samsung’s ultra-thin glass protects the internal foldable display from scratches on the level two on the Mohs scale, with deeper grooves at level three, similar to a piece of plastic. This will also make us think twice about the sharp nails around the screen when we open the phone with one hand.

Unsurprisingly, the flexible layer that protects the foldable screen gets very hot and physically deforms within seconds under the flame of a lighter. The 1.9-inch cover screen, on the other hand, only fades when exposed to heat and the Gorilla Glass Victus protector ensures that it is not easily scratched.
