Abstract

In order to combat increasing spam calls, many applications are developed and downloaded to block those calls. Some studies about performance of the applications were previously conducted, however, the actual processes the applications go through to intercept and block the spam calls are not well studied. This research presents a method to systematically explore Android APIs that are responsible for intercepting and blocking the spam calls.
