Mobile Device Forensics: Tools, Techniques, and Best Practices
Accelerate your investigation with our 2026 Cellebrite Quick Start Guide!
We’ve updated our eLab Forensics Cellebrite Quick Start Guide and online training for 2026 to improve the ability of public defenders to make the most of this critical data and to more effectively identify relevant insights.
We’ll show you how you can:
- Open, navigate and review reports
- Uncover hidden data
- Use filters and global searches
- Expedite your investigation
- Easily export custom reports
- Keep organized with our NEW investigator’s checklist
Use our guide for a repeatable process to review cell phone forensic extraction reports and our new check list for investigators to keep organized.
The process of obtaining digital evidence from cell phones presents numerous challenges, particularly in maintaining forensic soundness within this ever-changing landscape. Successful investigations depend on the early identification of evidence sources, not only from the devices themselves but also from service providers, cloud storage, and backup files. Proactive and thorough preservation strategies are essential for securing critical digital evidence.

Acquisition Types
NIST has defined the mobile device tool classifications system as follows:
Micro Read
Highest level of forensic examination, where the device memory chip is shaved in extremely thin layers and the data is read bit by bit from the source using an electron microscope or other device. It is extremely technical, and would only be used after all other means had been exhausted.
Physical or Hex Dump
The most comprehensive and forensically sound process. A complete copy of the device physical memory is obtained. Not all devices are supported for physical extraction and the strong encryption used by some devices prevents the data from being of value.
File System
This method obtains the user data and database files from the device and can recover some deleted data.
Logical
This is the simplest forensic extraction which obtains the user data that is available by the device user.
Manual
This involves operating and searching the device by hand and photographing the display. This could result in accidental deletion of data, and would change metadata such as an unread message to read.
