Cellebrite UFED is the standard tool for mobile forensic acquisition. Magnet AXIOM, MSAB XRY and Oxygen Forensic Detective serve the same market. They all do excellent work and they all cost between $4,000 and $20,000 annually for a meaningful deployment.
For many Android cases, particularly civil litigation, family law, employment investigation and small-agency law enforcement work, the case does not actually require what those tools provide. A logical acquisition over ADB produces the artifacts most cases need, at a fraction of the cost.
This guide is for the examiner, attorney or investigator deciding whether their Android case requires the enterprise mobile forensic stack or whether a focused logical-acquisition tool handles it.
Physical vs Logical Acquisition
Two acquisition modes matter for Android:
Physical acquisition. Bit-for-bit image of the device storage. Recovers deleted data from unallocated space. Bypasses screen locks via exploit chains. Requires expensive tooling (Cellebrite UFED Premium, GrayKey for iOS) and significant technical expertise. The gold standard for criminal cases where deleted content matters.
Logical acquisition. Software-mediated extraction of accessible artifacts via vendor APIs, ADB (Android Debug Bridge) or backup mechanisms. Recovers only what the device exposes through normal interfaces. Does not bypass screen locks. Does not recover deleted unallocated data. Sufficient for the majority of civil and many criminal cases.
A logical acquisition over ADB recovers:
- SMS and MMS messages with timestamps and contact info
- Call logs with duration and contact info
- Contacts and address book entries
- Calendar events
- Photos and media stored in accessible directories
- App data for apps that permit ADB backup or that store data in accessible locations
- Browser history and bookmarks
- Wi-Fi connection history
- Account information (the account names, not the credentials)
- Device metadata (IMEI, hardware ID, OS version, installed apps inventory)
A logical acquisition does not recover:
- Deleted SMS, deleted call logs or other deleted-but-not-yet-overwritten data from unallocated space
- App data from apps that explicitly block ADB backup (most secure messaging apps)
- Data behind app-level encryption without the user's credentials
- Anything that requires bypassing the device screen lock
For cases involving non-deleted communications, contacts, call logs and media (most civil cases, many criminal cases, most employment and family-law cases), logical acquisition is sufficient.
Why ADB-Based Logical Acquisition Is Often Enough
Mobile evidence in modern litigation usually centers on communications and device-use patterns:
- Custody and parenting disputes hinge on call logs, text messages and location-tagged photos
- Employment investigations hinge on text messages and contacts indicating relationships with competitors
- Civil litigation discovery requests typically request "all messages and call logs from device X for date range Y"
- Harassment matters hinge on text messages and call patterns
- Many criminal investigations begin with logical acquisition and only escalate to physical if the case requires it
For these cases, the deleted-data and screen-lock-bypass capabilities of Cellebrite UFED Premium are not actually used. The deliverable is a court-ready report of the messages, call logs, contacts and media and a logical acquisition tool produces that deliverable.
When deleted-data recovery or screen-lock bypass is actually required, no logical-acquisition tool covers it. Cellebrite, Magnet or MSAB remain the right purchase. Logical acquisition is for the cases that do not require those capabilities.
What Sherlock Forensics Android Acquirer Forensic Edition Does
Sherlock Forensics Android Acquirer Forensic Edition is a $399 logical-acquisition tool for Android devices. It connects to the device via ADB and extracts:
- SMS and MMS messages
- Call logs
- Contacts
- Calendar
- Photos, videos and accessible media
- Browser history and bookmarks
- Wi-Fi connection history
- App inventory and accessible app data
- Account information (account names, no credentials)
The extracted data is formatted into:
- Court-ready forensic PDF reports with cover page, source device metadata (IMEI, hardware ID, OS version), per-artifact inventory, SHA-256 hash table, examiner attestation, chain-of-custody footer
- CSV exports per artifact type for review-platform ingestion
- JSON exports for SIEM or custom-tooling ingestion
- A signed JSON chain-of-custody sidecar tying source device metadata to per-artifact hashes
The tool does not bypass screen locks. The device must be unlocked or the user-credential must be available. It does not recover deleted data from unallocated space.
The acquisition workflow is read-only with respect to the device, the tool requests artifacts via ADB and does not modify the device contents. The chain of custody is the standard forensic-grade pattern.
The Cost Comparison
| Capability | Sherlock Forensics Android Acquirer Forensic Edition | Cellebrite UFED | Magnet AXIOM |
|---|---|---|---|
| Logical Android acquisition | Yes | Yes | Yes |
| Court-ready forensic PDF report | Yes | Yes | Yes |
| SHA-256 per artifact | Yes | Yes | Yes |
| Chain of custody log | Yes | Yes | Yes |
| Physical (bit-for-bit) acquisition | No | Yes | Yes |
| Screen-lock bypass | No | Yes (Premium tier) | Limited |
| Deleted data recovery from unallocated | No | Yes (Premium tier) | Yes |
| iOS acquisition | No | Yes | Yes |
| Other mobile platforms (Windows Phone, BlackBerry, KaiOS) | No | Yes | Yes |
| Annual cost | $399 lifetime | $4,500-$15,000+ annual | $4,000-$10,000+ annual |
| Procurement friction | Self-serve purchase | Sales process, often 30-90 days | Sales process |
| Training requirement | Standard ADB familiarity | Cellebrite-specific certification recommended | Magnet-specific certification recommended |
For a case that only requires logical Android acquisition with court-ready output, the cost savings from choosing Sherlock over Cellebrite or Magnet are an order of magnitude. For an examiner handling several such cases per year, the per-case marginal cost approaches zero.
For cases involving iOS, physical acquisition, screen-lock bypass or deleted-data recovery, the enterprise tools remain the right purchase. Sherlock does not displace Cellebrite or Magnet for those cases, it complements them by handling the logical-Android cases that those tools are overqualified for.
When Sherlock Android Acquirer Is the Right Choice
- The case involves logical Android acquisition of an unlocked device or one for which the user-credential is available
- The deliverable is a court-ready report of messages, call logs, contacts and media
- The case does not require physical bit-for-bit imaging or deleted-data recovery
- The budget does not justify the $4,000-$15,000+ annual Cellebrite or Magnet license
- The examiner needs the tool today (self-serve purchase) rather than after a 30-90 day sales process
- The practice handles civil litigation, family law, employment investigation or small-agency law enforcement work
In these scenarios, the $399 lifetime cost recovers within the first case.
When Cellebrite or Magnet AXIOM Is the Right Choice
- The case requires physical acquisition or deleted-data recovery
- The case involves iOS in addition to Android
- The case requires screen-lock bypass on a locked device
- The case involves mobile platforms beyond Android (Windows Phone legacy cases, KaiOS, etc.)
- The agency or firm runs a high volume of mobile forensic work and the enterprise tools' broader capability surface justifies the cost
- The case involves court testimony where the examiner's familiarity with the established forensic standards is itself part of the credibility
In these scenarios, the enterprise tools earn their cost. Sherlock does not displace them.
