To meet these demands, commercial tools appeared which allowed examiners to recover phone memory with minimal disruption and analyse it separately.[1] Over time these commercial techniques have developed further and the recovery of deleted data from proprietary mobile devices has become possible with some specialist tools. Moreover, commercial tools have even automated much of the extraction process, rendering it possible even for minimally trained first responders—who currently are much more likely to encounter suspects with mobile devices in their possession, compared to computers—to perform basic extractions for triage and data preview purposes.
