Note:
Android development kit is not supporting complete replacement of outgoing and incoming interfaces for now. So, in case you are not satisfied with these interfaces then you can turn off and can use as a normal Phone Dialer App and still can enjoy rest of the app. Good support to this simple phone dialer helps me to give more free updates.
