Data extraction and analysis has been carried out by three tools Magnet Axiom, XRY, Autopsy. From the results of these outcomes, it was presumed that a considerable amount of essential data has been extracted from the Smartphone. This profitable data can be recovered by forensic analysts for future examination for the situation. In the end, tools were analyzed on the basis of their ability to extract evidence from the device and their performance has been examined with respect to NIST standards.
