When Apple first introduced iPhone X, the design met with its fair share of controversy. Although everyone appreciated the device's sharpness screen, it was difficult for many to pack their minds around the invisible chin. Certainly there was no way for Apple to embed the device's video and facial ID components below the screen, but many wondered why Apple simply did not choose to hide the score by making the tabs left and right of the image sensor black. Instead, Apple instructed all developers and users to fully embrace the chess.
A week or two after it was released, it became overwhelmingly clear that the uprising about the iPhone X cut was overblown. For a large majority of users, chopped, but perhaps annoying first, faded quickly into the background and became a non-factor. For a long time, we even began to see a lot of Android phone manufacturers start copying the iPhone X design, all the way down to the very chin. A couple of weeks ago, a photo of 20 Android phones with iPhone X-style hooks started making the rounds.
Interestingly, not all notch designs are created alike, and some of the Android copycats we've seen thus far have played terribly good implementations. As it turns out, there is more to the iPhone X notch design than meets the eye. When I just touched this time, I recently stumbled across an old Medium article from Brad Ellis explaining why the iPhone X cabinet looks much more aesthetically pleasing than many competing designs.
As Ellis points out, there are a lot of ways to implement a notch design, some significantly better than others. In turn, the direction Apple chose with iPhone X seems to work only for reasons that Ellis explains in detail.
Here's the nerd that comes in. The iPhone X-rounded screen corner does not use the classic rounding method where you move in a straight line and then bend with a single quadrant in a circle. Instead, math is a bit more complicated. Usually called a squircle, begins the height before, but is more mild.
Now let's talk about the booklet itself. The left and right sides have two rounded corners. Due to the basketfall, a curve does not end before the next begins ̵1; they are seamlessly blended into each other. As a result, no tangent line on this edge really hits a perfect vertical.
If you've been curious about why iPhone X just seems to be softer than a lot of Android copycats, you definitely want to check out Ellis's full piece – which includes a number of illustrative examples – here away.
