The role of a Digital Forensics Investigator (DFI) is rife with continuous mastering possibilities, mainly as generation expands and proliferates into every corner of communications, amusement, and enterprise. As a DFI, we deal with the daily onslaught of recent gadgets. Like the cell telephone or pill, many devices use unusual working structures that we need to be acquainted with. Certainly, the Android OS is essential within the tablet and cell cellphone industry.
Given the predominance of the Android OS in the mobile device marketplace, DFIs will run into Android devices within the direction of many investigations. While several fashions advise processes to acquire records from Android gadgets, this text introduces four possible strategies that the DFI should consider while proof accumulating from Android gadgets.
A Bit of History of the Android OS
Android’s first industrial release was in September 2008 with model 1.0. Android is an open-source and ‘loose to apply’ operating machine for cell gadgets advanced using Google. Importantly, early on, Google and other hardware groups fashioned the “Open Handset Alliance” (OHA) in 2007 to foster and aid the increase of Android within the marketplace. The OHA now includes 84 hardware companies and giants like Samsung, HTC, and Motorola (to call some).
This alliance changed into a setup to compete with companies with their marketplace offerings, including competitive gadgets offered by Apple, Microsoft (Windows Phone 10 – now reportedly lifeless to the market), and Blackberry (which has ceased making hardware). Regardless of whether an OS is defunct or no longer, the DFI must realize approximately the various variations of multiple working system platforms, especially if their forensics focus is in a selected realm consisting of mobile devices.
Linux and Android
The present-day generation of the Android OS is based on Linux. Keep in mind that “based on Linux” does now not mean the same old Linux apps will continually run on an Android, and conversely, the Android apps that you may enjoy (or are acquainted with) will not always run on your Linux laptop. But Linux is not Android. To clarify the point, please note that Google selected the Linux kernel, the important part of the Linux operating device, to control the hardware chipset processing so that Google’s builders would not need to be concerned with the specifics of how processing occurs on a given set of hardware. This lets their developers recognize the broader running device layer and the personal interface capabilities of the Android OS.

The Android OS has a vast market percentage of the cell tool marketplace, primarily due to its open-supply nature. Over 328 million Android gadgets were shipped in the 0.33 quarter of 2016. And, in step with netwmarketshare.Com, the Android working system had the most installations in 2017 — nearly 67% — as of this writing.
