We want developer to create a custom call screen.
Main screen with 4-6 contacts with pictures and name...
Second screen calling and receiving call screen...
Core functionality: It needs to show a full screen photo of an existing contact along with the functional "Accept" and "Cancel" buttons. Screen should popup on incoming or outgoing calls automatically.
App should function on all major brand phones (Samsung, HTC, Motorola, Sony, LG) and android versions (4+).
Finished application needs to be delivered as a buildable Android Studio project preferably without 3rd party libraries/tools.
