- "access to device location": Location access is necessary for mapping and contributing data, enabling us to accurately record the location of network information.
Permissions on Older Android Versions:
- android.permission.ACCESS_COARSE_LOCATION: Used to obtain CellID information.
- android.permission.ACCESS_FINE_LOCATION: Used to obtain gps location data.
- android.permission.ACCESS_NETWORK_STATE: Used to gather cellular network information.
- android.permission.INTERNET: Used to connect to our servers for downloading map data and uploading user contributions.
- android.permission.READ_EXTERNAL_STORAGE: Used to write external CSV files when no internet connection is available.
- android.permission.READ_LOGS: Used to read Samsung Field Test mode data on Android 4.1 and earlier (Note: This does not allow the app to read your browsing history unless your browser writes it to the system log).
- android.permission.READ_PHONE_STATE: Used to read information about airplane mode and network settings.
- android.permission.RECEIVE_BOOT_COMPLETED: Used to start the app at boot time (if enabled by the user).
- android.permission.VIBRATE: Used to provide vibration feedback on CellID change (if enabled).
- android.permission.WAKE_LOCK: Used on older phones that lack 4.2+ CellID Support, ensuring accurate data reporting.
- android.permission.WRITE_EXTERNAL_STORAGE: Used to write external CSV files and debug reports.
