Reconstructing user activity on Android devices often presents severe evidentiary challenges for legal practitioners needing to establish whether a handset was unlocked, which applications were active, and how specific events unfolded over time. Aimed at UK lawyers instructing digital forensics specialists, this resource details how internal device logs, usage statistics, Digital Wellbeing records, notifications, and screen, lock, or battery events form a detailed chronological diary of interaction. It explains how examiners interpret these system artefacts, account for manufacturer variations, and address technical limitations such as data rotation and aged-out records. Crucially, the material spans both technical analysis and legal practice, outlining source architecture across Google accounts, live devices, and paired wearables alongside practical guidance on instructing experts under CPR Part 35 and CrimPR Part 19. By setting out worked examples, draft questions for clients or opponents, and essential red flags, it provides practitioners with a rigorous framework to verify timeline evidence, evaluate chain of custody, and correctly deploy Android activity data in litigation.
