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.INTERNET - To connect to server to download map data / upload data
android.permission.READ_EXTERNAL_STORAGE - To write external CSV file if no internet connection
android.permission.READ_LOGS - To read Samsung Field Test Mode data on Android 4.1 and earlier (despite what the dialog says, the app cannot read your browsing history unless your browser write it to the system log)
android.permission.READ_PHONE_STATE - To read info about airplane mode / network settings
android.permission.RECEIVE_BOOT_COMPLETED - To start at boot time (if enabled)
android.permission.VIBRATE - To vibrate on CellID change (if enabled)
android.permission.WAKE_LOCK - For phones that do not support 4.2+ CellID Support, to ensure they report correct data
android.permission.WRITE_EXTERNAL_STORAGE - To write external CSV file and debug report
