How to Recover Deleted Media, Documents, WhatsApp Chats & Call Logs on Android Phones
Introduction
In today’s digital world, images, videos, documents, WhatsApp chats, and call logs often hold valuable personal and professional information. Losing this data due to accidental deletion, formatting, or intentional erasure can be stressful.
Fortunately, Cellebrite UFED — one of the most advanced mobile forensic tools — allows experts to extract, analyze, and recover deleted data from Android devices. In this article, we’ll explain how Cellebrite UFED helps recover deleted data from Android devices and share a real-world case study where we successfully recovered all deleted files.
Common Reasons for Data Loss on Android
Data can be deleted or lost for several reasons, including:
- Accidental deletion
- Factory reset or OS updates
- Corrupted storage
- Intentional deletion during investigations
Step-by-Step Android Data Recovery Using Cellebrite UFED
1. Preparing the Device for Extraction
Before starting the extraction process, forensic experts prepare the Android device to preserve data integrity:
- Enable Airplane Mode to prevent remote wipe commands
- Disable biometric authentication
- Connect the device securely to the Cellebrite UFED workstation
2. Selecting File System Extraction
The Full File System Extraction feature of Cellebrite UFED allows access to the entire Android file structure, including deleted and hidden data.
Why Full File System Extraction Is Best for Recovery
- Extracts all app data, including WhatsApp, Facebook, Instagram and more
- Recovers deleted photos, videos, documents, and Whatsapp call logs
- Maintains the original file structure for forensic analysis
By extracting the entire file system, investigators get access to deep-level storage sectors, increasing the chances of recovering deleted files.
3. Recovering Deleted Photos & Videos
Cellebrite UFED scans the internal storage, thumbnails, and cache to retrieve deleted media files. Even if the gallery shows “empty,” the deleted images and videos can often be recovered during analysis.
4. Recovering Deleted Documents & Files
Using Full File System Extraction, UFED can restore deleted documents, including:
- PDF, DOCX, and XLSX files
- Presentations and reports
- Downloaded app files
5. Recovering WhatsApp Chats, Media & Call Logs
Cellebrite UFED’s Full File System method allows investigators to:
- Recover deleted WhatsApp messages, group chats, and attachments
- Retrieve deleted media files such as images, videos, and voice notes
- Extract deleted WhatsApp call logs (incoming, outgoing, and missed)
- Access WhatsApp’s internal database files to rebuild deleted conversations
Case Study: Successful Deleted Data Recovery Using Cellebrite UFED
On 8th September 2025, we conducted a controlled forensic test to evaluate Cellebrite UFED’s Full File System Extraction capabilities on an Android device.
Scenario Details:
- Deleted WhatsApp call logs

- Deleted a PDF document named FT508211134458.pdf, downloaded on 4th September 2025
- All deletions were performed on 8th September 2025 at 12:30 PM
At 5:30 PM on the same day, we started Full File System Extraction using Cellebrite UFED. Once the extraction was completed, we analyzed the acquired data in detail.
Result:
All the deleted photos, videos, WhatsApp chats, call logs, documents, and screen recordings were successfully recovered during the forensic analysis.
This case proves that Cellebrite UFED’s Full File System Extraction is one of the most effective methods for retrieving deleted Android data, even when the files were intentionally removed.
