iPad Mini 3 - Removing standard built-in apps
You cannot uninstall or hide the default Apple apps.

You can set up Restrictions [parental controls] to prevent access to particular apps or age-related content.

Word of warning - don't forget the passcode or you'll have to wipe the phone &amp; start over.

Settings > General > Restrictions. Enable Restrictions &amp; enter a passcode.

When an option is on, or you see a checkmark next to an item, that means you're allowing access to that item. Turn options off to restrict access.
