Mobile Device Forensics
Expert forensic examination of smartphones, tablets, and wearable devices for litigation. Court-admissible extraction of texts, call logs, location data, app content, and deleted communications using Cellebrite and Oxygen Forensic tools.
Overview
Mobile devices contain some of the most compelling evidence in modern litigation — text messages, call records, location history, photographs with embedded GPS coordinates, app usage data, and communications across dozens of messaging platforms. Our mobile forensics services provide forensically sound extraction and analysis of iOS and Android devices using Cellebrite UFED, Oxygen Forensic Detective, and GrayKey — industry-leading platforms with extensive court acceptance. We recover deleted text messages, extract encrypted messaging app content (WhatsApp, Signal, Telegram), reconstruct location timelines from GPS and cell tower data, and analyze app-specific databases that reveal user behavior patterns. Every extraction maintains strict chain of custody with cryptographic hash validation, ensuring admissibility under Daubert and Frye standards.

Frequently Asked Questions
Can you recover deleted text messages from a smartphone?
Yes, deleted text message recovery is one of our most requested services. For iPhones, deleted messages often remain in the SQLite database until overwritten and can also be found in iCloud or iTunes backups (up to 180 days of backup history). Recovery rates for recently deleted messages (days to weeks) are typically 60-90%. For Android devices, deleted SMS/MMS messages remain in databases until overwritten with 70-85% recovery rates for recent deletions. WhatsApp messages can be recovered from local databases and Google Drive or iCloud backups. Time is critical — contact us as soon as possible to maximize recovery chances before deleted data is overwritten by normal device usage.
Can you extract data from a locked phone?
In many cases, yes. Our forensic tools (Cellebrite, GrayKey, Oxygen) include capabilities for accessing locked devices through vendor-supported forensic methods. Success depends on the device model, operating system version, and security configuration. We always require proper legal authorization (owner consent, attorney direction, or court order) before attempting locked device access. For devices we cannot unlock, we may still recover evidence from cloud backups (iCloud, Google) or carrier records. We provide honest assessments of extraction likelihood before engagement so counsel can make informed decisions about forensic investment.
How accurate is phone location data for litigation purposes?
Phone location data varies in precision depending on the source. GPS coordinates from photos and mapping apps are accurate to within 3-10 meters. Cell tower triangulation data from carrier records provides accuracy within 100-1000 meters depending on tower density. Wi-Fi connection logs can place a device within range of a specific access point (typically 30-100 meters). Google Maps Timeline and Apple Significant Locations aggregate multiple sources for comprehensive movement history. We present location evidence with appropriate precision disclaimers and can testify to the technical basis and limitations of each data source, ensuring location evidence withstands cross-examination.
What types of mobile devices can you examine?
We examine all major mobile device platforms including all iPhone models (iPhone 4 through current), all iPad models, Android smartphones from all manufacturers (Samsung, Google Pixel, OnePlus, Motorola, LG, Huawei, and others), Android tablets, Apple Watch and other smartwatches, and basic/feature phones. Our lab supports over 35,000 device profiles through Cellebrite UFED and maintains current extraction capabilities as manufacturers release new models and operating system updates.
How much does mobile forensics cost?
Mobile forensic examination costs typically range from $2,500-$6,000 per device for standard extraction and analysis, including a forensic report suitable for litigation. Factors that affect pricing include device complexity (locked vs. unlocked, encryption status), scope of analysis required (full extraction vs. targeted review), number of messaging apps requiring analysis, deleted data recovery requirements, and urgency. Expert witness testimony is billed at $350-$500/hour. We provide detailed scoping and cost estimates after initial consultation so counsel can budget appropriately and make informed decisions about which devices warrant forensic examination.
