Agar call recording delete hui hai toh pehle apne recording app ka trash ya recycle bin check karo - aksar 30 din tak wahi rakhti hai. Agar cloud backup (Google Drive ya automatic backup) enabled tha toh wahan se restore kar sakte ho. Nahin mila toh data recovery apps try kar sakte ho but success rate kam hai, mostly overwrite ho jaati hai storage pehle.
