The vast usage of mVoIP applications on Android devices has made it easier to share information between smartphone users which heavily increased the amount of data and traffic transferred on these applications and also made them a goldmine for mobile forensic investigators. This paper presents forensic investigation of top three mVoIP applications of Google Play store namely Skype, Viber and WhatsApp Messenger left on Android devices. The experiments consist of installing the mVoIP applications on the device, conducting usual user activities, acquiring logical image in a forensically sound manner, and then perform a manual forensic analysis on each of the installed mVoIP applications. The contribution of this research include the recoverable artifacts of WhatsApp, Skype and Viber on android platform which can be used by forensics practitioners as evidences in real cases.
