+> **Note:** On Android 10+, GPS data is redacted from `content://` URIs by default. The library automatically requests `ACCESS_MEDIA_LOCATION` at runtime to access unredacted location data. Your app must have media read access (`READ_MEDIA_IMAGES` or `READ_EXTERNAL_STORAGE`) granted first. If you're already using a library like [`expo-media-library`](https://docs.expo.dev/versions/latest/sdk/media-library/) that grants `ACCESS_MEDIA_LOCATION`, exify will use the existing grant.
