Example 4:
The working mode 4: under this working mode, when there is an incoming call, the device will fist
hang up the incoming call. Then it will send its current location to each incoming call
number via SMS with a Google Maps hyperlink. This mode is mostly used in an emergency
situation while you do not want the device notifies that there is an incoming call. Beware, under
this mode the users of the device will never know there is an incoming call nor can they pick it up.
