Abstract
Due to the rich set of exciting features available in Android smartphones makes it possible to be used vastly by the user around the world and hence android occupies a large share from among other operating system based Smartphone. The popularity of Android smartphones is growing rapidly day by day and it plays a vital role in our daily lives. The feature-rich state of Android smartphones makes it possible to be used in criminal intended activities. The Android smartphones are merely used in criminal activities and hence it can be used as a solid source of digital evidence. A range of Smartphone's forensics tools are available in the market which can be used to recover digital evidence from the Android smartphones. In this paper, authors have made efforts to highlights the range of Smartphone forensics tools which can be used to perform logical acquisition on the internal memory of android based smartphones and then provide the comparison between Smartphone forensics tools on the basis of their ability to acquire data from the internal memory of Android smartphones. It has been found that there no tool available which can extract the complete range of digital evidence from Android-based smartphones.
