One of the subtle, unmentioned changes of iOS 7 it has to do with the system that allows display on iPad of applications made especially for terminals iPhone, Apple Lossless Audio CODEC (ALAC), improved way of retrieving the graphic elements available in them. Specifically, iPhone applications will be displayed automatically on the full screen of iPad tablets that do not have Retina Display, Apple Lossless Audio CODEC (ALAC), eliminating the option that allowed us to view them in 1x/2x mode. This system is still available for iPad tablets with Retina Display, but those without this screen automatically display the applications on the entire visible surface, exactly as you see in the image above.
Interestingly, on the latest iOS 7 beta users are no longer even presented with a 1x/2x toggle on non-Retina devices such as the iPad mini, and iPhone apps are instead presented simply as 2x apps taking advantage of Retina assets included in the app package. The result is a much better looking 960×640 app on the iPad's 1024×768 screen. Retina iPads have not, however, seen any changes to their handling of iPhone apps and continue to offer the 1x/2x toggle.
iOS 7 automatically takes all Retina graphics elements of iPhone apps and uses them to display apps dedicated to tablets iPad, even if they are made at a lower resolution. This system anyway doubles the pixels to display on the iPad applications made for iPhone terminals, but if you look at the image, you will realize that on the iPad Mini an application for iPhone will look much better in iOS 7 than in iOS 6. The system change is welcome, because now the quality of the applications will be better, and users will no longer have a choice between the 1x mode, which displays their applications only in the center of the screen.
The change will be available to everyone as soon as iOS 7 is released publicly, but now anyone can test it if they have iOS beta 7 3 installed.
