    We specialize is cellular device forensics and the vast majority of devices we analyze are Android based. We have a thorough understanding of the file-systems employed by Android devices, common repositories of operating system artifacts, and most common user app artifacts . Additionally, we employ specialized digital forensic tools and knowledge for the analysis of SQLlite databases. SQLlite is the underlying database technology used by the Android OS and third-party applications. Data realized from this low-level analysis can be very valuable and is commonly overlooked by most forensic consultants relying on only traditional forensic software and equipment. As digital forensic examiners we may occasionally reference available source code but this not common (case specific basis). Control testing is much more commonly required and this is especially true in distracted driving cases such as you describe. For example, if we find that a user is interacting with a specific app near the time of accident, it may be necessary to run test case scenarios on a control device and observe how data is stored and/or affected.
