How to Read a Cellebrite Report: A Guide for Attorneys

Your forensic examiner just sent you a 400-page Cellebrite report.

You have a hearing in 48 hours.

Here’s how to read it without calling the examiner for every line.

What a Cellebrite Report Contains

A standard Cellebrite Physical Analyzer report is divided into sections. The structure varies slightly depending on how the examiner customized the output, but most reports include:

Cover page / Case information: Examiner name, certification, case number, device details, extraction date, and hash values. This page matters for chain of custody — check that the hash values are documented.

Device summary: Make, model, IMEI, phone number (if stored on device), iOS/Android version, and serial number. Confirms you have the right device.

Extraction summary: What method was used (logical, advanced logical, file system, physical), what tool version, and what data categories were recovered.

Data sections: This is the bulk of the report. Typically organized by artifact type — messages, calls, contacts, web history, locations, apps, photos, etc.

Understanding the Message Sections

Messages are usually the highest-priority section for litigation.

SMS Messages: Listed with sender/recipient phone number, timestamp (usually in UTC), direction (sent/received), and content. Some reports also show “delivery status.”

iMessages: Similar format, but identified by Apple ID or phone number. Note that iMessage is tied to an Apple ID, which means the same thread can appear on multiple devices (iPhone + iPad + Mac). The examiner’s report should specify which device the messages came from.

Third-party apps: If WhatsApp, Telegram, or other apps were parsed, they appear as separate sections. Look for the field that identifies the account associated with the app — this is how you tie the messages to a specific person.

What “Status: Deleted” means in the report: If a message row shows “Deleted” in the status column, it was recovered from database free space. It was present on the device at some point but was marked for deletion. The content shown is what was recovered — treat it as evidence but be ready to address chain of custody for deleted items specifically.

Timestamps: The Most Common Source of Confusion

Cellebrite reports display timestamps in UTC by default.

San Diego (Pacific Time) is UTC-7 in summer (PDT) and UTC-8 in winter (PST).

So a message showing a timestamp of 2026-03-15 19:43:00 UTC was actually sent at 12:43pm PST on March 15th, 2026.

This seems obvious until you’re in a hearing arguing about what time someone sent a text and you haven’t accounted for the time zone offset. Check the report to see if the examiner converted timestamps to local time or left them in UTC, and apply the offset consistently.

Call Logs: What the Fields Mean

A call log entry in a Cellebrite report includes:

Missed calls with zero duration are calls that weren’t answered. Note that a “missed” call shows the other party attempted contact — this can matter in harassment or contact-dispute cases.

Location Data: GPS and Cell Tower History

Cellebrite reports often include location data from multiple sources:

GPS coordinates from photos: Every photo taken with location services on embeds GPS coordinates in the EXIF metadata. The report maps these. This places a person at a specific location at a specific time.

App location data: Maps apps, ride-share apps, delivery apps, and fitness apps all log location. Cellebrite surfaces these from the app databases.

System location history: iPhones store a “Significant Locations” database. Android devices have a Google Location History. Both are extracted and mapped in the report.

Cell tower records: These are metadata, not GPS — they show the approximate cell tower the phone connected to, giving a geographic area, not a precise point. Don’t let an expert claim a cell tower ping proves someone was at a specific address.

The Hash Values: Why They Matter

Every Cellebrite report should document a SHA-256 or MD5 hash of the extracted data.

The hash is a fingerprint. If the hash of the evidence file matches the hash computed at time of extraction, the data hasn’t been altered.

If the hash is missing from the report, opposing counsel should ask why. A report without hash documentation has a meaningful chain of custody gap.

Red Flags in a Cellebrite Report

Watch for these problems:

Any of these can be grounds for challenging admissibility or weight.

FAQ

Do I need to read the entire 400-page report?

No. Use the report’s table of contents (most have one) to jump to relevant sections. If the case turns on text messages, go directly to that section. If it turns on location, go there. You can reference other sections if something unexpected comes up in testimony.

What if timestamps don’t match what my client says happened?

First verify the UTC offset. Then ask the examiner whether the device’s internal clock matched real time at extraction — clocks can drift or be manually set. If there’s still a discrepancy, it warrants investigation.

Can I get the raw data file instead of the PDF report?

Examiners typically provide the PDF report for attorney use. The raw extraction file (UFDR format) requires Cellebrite Physical Analyzer to open and is usually not shared absent a court order. You can request a more detailed export of specific data sections if needed.
