A YouTuber has demonstrated the resilience of the iPhone Duo display, which seems to explain why there are so few reports of broken units just after launch.

There are some inevitabilities that happen after the launch of a new Apple product. We have seen the initial reviewers' opinions, as well as a close examination of mechanisms, but now we have turned to the destruction phase of the iPhone Duo release.

Released early on Saturday, the video by JerryRigEverything looks at the iPhone Duo and then destroys it in various ways within a few minutes. However, unlike others that sensationalize the destruction for clicks, the channel instead takes a fairly structured and measured approach.

In a scratch test through the Mohs Hardness Scale, the Ceramic Shield-protected front display manages to reach level seven. That's just below the level 8 or 9 of sapphire.

The same cannot be said about the flexible inner display, which does scratch at a level two implement, forming deeper grooves with a fingernail. This is similar to practically all other foldable devices on the market, so Apple isn't alone here.

That said, its multi-level approach with a matte nano-texture finish does help hide any scratches while turned on. Keys, coins, and chain mail armor do leave marks, but they practically disappear when the screen is turned on.

The rest of the video devolves into a series of tests that reveal obvious things. Using a knife on the titanium edge will scratch it, while using a lighter will singe and mark the internal display.

Pouring a massive amount of dirt and dust then opening and closing it does eventually result in a clogged hinge that won't allow it to stay closed. The lesson here is not to bury the iPhone Duo in the sand on a trip to the beach.

As a reminder, quartz sand is 7 on the Mohs scale of hardness, generally harder than glass.

Eventually, a bend test is conducted, trying to "close" the iPhone Duo the wrong way with the large screen on the external side. After exerting a lot of pressure with the thumbs, and some disconcerting cracking sounds, the iPhone Duo does survive, albeit after flexing quite a lot.

The screen did develop a line fault on one side after the first attempt, with more developing after a second attempt. The hinge does allow enough flex for the display to get damaged, but ultimately it doesn't allow the screen to fully snap the iPhone in half.

Surprisingly few issues

The video shows that, with enough effort and disregard for financial matters, you can damage an iPhone Duo, which isn't really a thing anyone needed to learn. However, the amount of effort required to seriously damage the internal display without breaking the central creased section nor the hinge shows that it's not as fragile as people may think.

That middle section is still the most vulnerable part, and consumers are also finding that out live.

Posts to the iPhone Duo subreddit show users complaining of cracked screens happening a short time after picking up their devices. In most of the instances, there is a definite central fold and screen issues from the center to the edge.

While alarming in isolation, it's also something that's happening at a far lower rate than people may think. Posts to social media of broken iPhones are always alarming, but it doesn't show how widespread a problem is.

There is always some form of infant failures in Apple product releases, simply because of the sheer number of sales. But even then, it seems to be quite low for the iPhone Duo.

AppleInsider called sources we have worked with for over 15 years that work inside Apple Genius bars at seven stores, including four major flagships. None of the stores polled have seen any devices in for service or returned because of broken screens.

While the worries are understandable, and if it bleeds it leads, especially on social media, the reality is that the iPhone Duo is more formidable than you'd think.

Except if you want to record a YouTube video destroying one.
