YouTube user Tom Rich has published an interesting video showing a rendering of the iOS 8 on the future iPhone.
However, some special effects were used. The screen of the iPhone 6 mockup is not able to function as a true smartphone and video editing techniques were necessary.
The clip presents the operating system on a 4.7-inch screen with 4 rows of home screen icons that appear larger than on the iPhone 5S.
The author of the video just stretched all the icons to see how they appear enlarged or how comfortable a wider keyboard would be.
Apparently, despite a larger display, navigating through menus and applications with one hand remains fluid and natural.
