If you have for some weird reason lost your settings app... and need to access for one time only
Go to the app store and download any app which will require a camera. For example: QR Reader
Open the app and you will be presented with a box saying give the app permission to use camera. Press cancel or no can't remember what the option was but don't press yes/ok. It will then say. Please go to settings app to grant permission and it will say cancel or settings. click the settings option and you will be taken to the settings app.
