IOS 9 will remove apps to save space for system upgrades
Early adopters of IOS 9 Beta 2 discovered a new feature that temporarily removes apps on an overloaded device when there is not enough room to install a system upgrade. It is reported that many users of iphones with smaller memory 8GB and 16GB have difficulty adapting the latest upgrades to their mobile devices. And while iOS 9 is only a fraction of the size of iOS 8 (they are 1.3GB and 4.3GB respectively), Apple is clearly trying to wipe out similar complaints in the bud this time. Of course, the new feature will reinstall deleted apps after the upgrade is complete, and may contain user data that has been deleted with apps.
