Mobile Device Preservation: State, Isolation and Source Records
Edition 2026-11-03

A phone changes through its own activity as well as through the network. This checklist records the handset’s state, arranges a handling plan the examiner directs and identifies the device, account, backup and vehicle sources before anything is reset, reissued or traded in.

Contents

mobile_device_preservation_checklist.html          The checklist with its guidance, sources and contacts. Open it in any browser or print it.
mobile_device_preservation_checklist_workbook.csv  The working checklist. Open it in Excel or any spreadsheet and fill in one row per item.

How to use it. Read the checklist page first. Then open the CSV, assign an owner to each row and record the date each action happens. Update the Status column as the work is recorded. In the evidence column, record an evidence ID or the location of your secure repository, where passwords, recovery keys and the evidence itself are kept. When you are ready to begin, call GDF and a senior examiner will walk through the checklist with you.

Talk to a senior examiner. The initial consultation is free. Call (800) 868-8189 at any hour, or write to info@evestigate.com.
