Apple employed some clever solutions for the interface navigation on its first “bezel-less” handset, the iPhone X. Instead of hitting a home key, you simply swipe from the bottom to get to base, or hold the touch to access your recent apps.
Alternatively, you can swipe left and right at the bottom where the home indicator is to go back and forth between apps, neat. Pulling down on the left or right of the “notch” will get you the control and notification centers, while holding the lock key will start Siri.
That’s it, with a few little gestures, Apple negated the demand for a physical home button, got around the bezel “notch” at the top that is the only thing eating into the 5.85″ display space, and at the same time avoided replicating Android’s virtual navbar that’s been around for a while. When it comes to actually displaying stuff on the iPhone X, though, developers are advised that their apps need to account for the new aspect ratio and the notch that eats into the actual display area. Here are the troubles and UI differences that native and third-party apps are supposed to adjust to on the “all-screen” iPhone X.
Display area
We know you are curious how does the new bezel design and aspect ratio of the iPhone X affect its actual viewable screen size when compared to the iPhone 8/Plus. Well, it offers about 20% extra vertical space than the iPhone 8, says Apple, but the screen area is a tad smaller than what the 8 Plus has – about 12.8 vs 13 square inches – on account of the difference in aspect ratios and the notch.
Video
The iPhone X is wiggling into the trendy 2:1 Univisium aspect ratio that most new movies and TV series are being shot with. While it technically has 1125 x 2436 pixels resolution (2.17 aspect), taking into account the status bar around the notch, which Apple advises app developers not to cover unless it will contribute to the experience, the iPhone X covers the Univisium standard to the letter. Samsung does something similar with its 2.05 ratio on the S8/S8+/Note 8, while the LG V30 directly goes to 2:1 (1440×2880 resolution).
That’s all fine and dandy, but how many movies and TV series are there recorded in 2:1? The answer is not that many, and for now the vast majority of content has been made with other standards, including YouTube clips. The result is that on all these new flagships, the iPhone X included, standard videos get cropped, letterboxed or stretched out of proprtion – pick your poison. How did Apple address this issue?
Well, it seems that regular vids show letterboxed, but double-tap on the screen, and they fill out the display completely, save for the notch area, of course. Some may find this distracting, but remember that the S8 or the V30 also crop, stretch or box, there’s just no other way around it for now. Letterboxing will diminish the viewable area probably to around the size the video is on the iPhone 8, while stretching will bring you the notch eyesore while watching – again, pick your poison.
Browsing
Reading and browsing is where the new aspect ratio shines on phones like the iPhone X, S8 or V30. Since we get a much larger vertical space compared to the 16:9 brethren, the iPhone X displays more of the page than the 8 Plus, despite having a similar screen area, not to mention the iPhone 8, where you will have to scroll much more to read the same amount of content.
Apps
Well, here things get trickier. Apple is advising all developers to account for the notch, and not to cover the status bar area on its left and right unless it is necessary, and brings something meaningful to the interface of their app. This means that for the majority of apps, their display will end up to the notch, reducing the actual screen area from the official 5.85″ screen diagonal. Moreover, Apple warns devs to be aware of the margins at the rounded display corners, and at the home bar indicator at the bottom, hiding it only in situations where it is needed, like watching vids or pics. Mind the gap, as the Brits would say.
Landscape mode
One thing is becoming increasingly clear – landscape mode on the iPhone X will present a bigger challenge, as even Safari appears with white bars on the sides, depending on the website background, and as a result the vertical space of the iPhone X in that position is said to be in the realm of iPhone 8. Check out all the ways that developers are battling with the new iPhone X interface in order to circumvent or incorporate the “bezel-less” design.
