Rumor: iPad Air 2 split-screen feature may also be coming to iPad mini 4
One of the notable changes to the upcoming iOS 9 is that the larger iPads can run applications side by side on the screen, in this case only the iPad Air 2. The feature also appears to be coming to a future iPad mini, according to a test screen. at El Capitans Safari.
In an environment where developers can simulate website scalability in the test version of Safari 9 on OS X El Capitain, there is also an iPad mini 3, writes 9to5mac. That while this functionality would only come to the iPad Air 2. The test versions of OS X El Capitan and iOS 9 were released in early July. Whether the feature will actually be available for the iPad mini 3 is unclear.
Since both the test option and a settings icon are available in the El Capitan Safari version, 9to5mac believes the functionality will be in a future iPad mini update. The news site further believes that the iPad mini 4 will be a bigger update than the previous iPad mini update. The future gem will probably get better camera sensors and a faster processor. With the latter, the device can better run two applications at the same time, something that works less smoothly with lighter processors, so that it is not turned on in older devices.
