Permissions
Why does CellMapper need so many permissions?
"make and manage phone calls" - This is required to get low level network data from your device
"access to device location" - In order to map and contribute, we will need to know where the data was recorded from your device.
Older versions of Android:
android.permission.ACCESS_COARSE_LOCATION - To get CellID information
android.permission.ACCESS_FINE_LOCATION - To get GPS location
android.permission.ACCESS_NETWORK_STATE - To get Cellular network information

android.permission.READ_EXTERNAL_STORAGE - To write external CSV file if no internet connection
