See which applications asked for your location

1. Open Location Services.
2. Look under Application Access. It lists the applications that have asked for your location, with your answer.
3. To change an answer, tap the application and choose Allowed, Denied or Ask Again. Some applications show Allowed (system) or Allowed (by app). Those were set when they were installed.

If the list is empty, no application has asked yet. To change whether applications can use your location at all, see Manage location information passed to applications.
