Brightness & Wallpaper
Screen brightness affects battery life. Dim the screen to extend the time before you need to
recharge iPod touch.
Adjust the screen brightness: Go to Settings > Brightness & Wallpaper and drag the slider. If
Auto-Brightness is turned on (iPod touch 4th generation only), iPod touch adjusts the screen
brightness for current light conditions using the built-in ambient light sensor.
Wallpaper settings let you set an image or photo as wallpaper for the Lock screen or Home
screen. See
Changing the wallpaper on page 21.
Privacy
Privacy settings let you see and control which apps and system services have access to Location
Services, and to your contacts, calendars, reminders, and photos.
Location Services lets location-based apps such as Reminders, Maps, and Camera gather and
use data indicating your location. Your approximate location is determined using available
information from local Wi-Fi networks (if you have Wi-Fi turned on). The location data collected
by Apple isn’t collected in a form that personally identifies you. When an app is using Location
Services, appears in the menu bar.
Turn Location Services on or off: Go to Settings > Privacy > Location Services. You can turn it off
for some or for all apps and services. If you turn off Location Services, you’re prompted to turn it
on again the next time an app or service tries to use it.
Turn Location Services off for system services: Several system services, such as location-
based iAds, use Location Services. To see their status, turn them on or off, or show in the
menu bar when these services use your location, go to Settings > Privacy > Location Services >
System Services.
Turn off access to private information: Go to Settings > Privacy. You can see which apps have
requested and been granted access to the following information:
•
Contacts
•
Calendar
•
Reminders
•
Photos
•
Bluetooth Sharing
•
Twitter
•
Facebook
You can turn off each app’s access to each category of information. Review the terms and privacy
policy for each third-party app to understand how it uses the data it’s requesting.
