How do I get original apps back when they disappear?
When an original app like app store or notes disappear how can you get them back?
Since they aren't in the app store you can't download them.
iPhone 5, iOS 8.3
App Store, Notes, and other apps that are embedded in iOS cannot be removed. They are on your iPhone somewhere.
You might try Settings > General > Reset > Reset Home Screen Layout.
Otherwise use Spotlight to search for them.
