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. 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 iPhone Duo is quite significant, and it's unlikely that many users will experience such issues in normal use.
