Here's how you can turn off Location Services on an Apple device. From the 'Settings' app, tap 'Privacy' to open the privacy settings for your device.
Then tap 'Location Services' to access your location services settings.
From here, you can turn all of your Location Services on and off by tapping the slider button to the right of 'Location Services' at the top of your screen.
You can swipe up to view a list of all the apps installed on your device that use Location Services. Tap any app in the list to control the Location Services for that app. Turning off Location Services for the Camera app will turn off Geo-Tagging.
