I Watched Apple's September Event. The iPhone Duo Surprised Me Most.

Apple's first foldable iPhone hides its crease better than I expected, and its under-display camera is a bigger technological leap than Apple usually makes this early.

Earlier this month, I watched Apple's September event, and the product that caught my attention most was the new iPhone Duo. Apple's first foldable iPhone opens into a much larger display, but what surprised me most was how well Apple managed the crease. Foldable phones have always had an obvious line running through the middle of the screen, but on the Duo, the crease is surprisingly difficult to notice when looking at the phone straight on. Even early hands-on reports found that it was mostly visible only from certain angles or under particular lighting.

Another thing that surprised me was Apple's decision to put a camera underneath the display. Apple has always seemed extremely focused on making its products feel polished, and under-display cameras have traditionally come with compromises in image quality and display clarity. Because of that, I did not expect Apple to use the technology yet. It feels slightly unusual for a company known for waiting until a technology is mature before putting it into a major product.

The foldable itself also feels very different from what I expected from Apple. Instead of simply making a normal iPhone thinner or faster, the Duo changes the basic shape of the device. When folded, it works like a phone, but opening it gives you a much larger screen without needing to carry a tablet separately.

What stood out to me most was that Apple did not necessarily invent the foldable phone. Other companies have been making them for years. Instead, Apple seems to be focusing on taking an existing idea and making the small details feel more refined. The crease, the hinge, and the overall design are the parts I will be watching most closely as people start using the Duo every day.
