The iPhone Duo has now been released, and it looks like early adopters are having to deal with some teething problems. As lucky as they might have felt to snag the sought-after foldable on release day, a bunch of people have reported their screens are cracking — a problem now dubbed "crackgate."

As it always does with new phones, iFixit got hold of the iPhone Duo and took it apart to see how everything works — and whether it's actually repairable or not. That teardown seems to have been very enlightening, revealing some secrets of the hidden hinge, factors that may be behind crackgate, and just how well that phone stands up to dust.

It's also the most repairable foldable phone to date, though other foldable phone makers haven't left the bar particularly high.

The Duo's nano-texture coating is easily removed, and while replaceable, it is a multi-part process. In the meantime, the Duo's display is far more vulnerable to scratches and other damage. Removing it also removes the light-scattering effect, which makes working in bright light much more difficult and means any imperfections in the screen are easier to see — including the crease.

Under the microscope, iFixit can see the textured layer that diffuses incoming light, and looking further shows the pixel layout in the screen itself. Curiously, Apple has adopted a unique (and patented) pixel layout with a mix of round and ovular pixels. Apple says that this is meant to add variation to the pattern, but doesn't say what the benefit is.
