[Q] how can I recover database.db from internal storage? topic

So I got myself a new phone note 4. I used that new Samsung transfer apk first time ever. After it completed I factory reseted my old phone note 3. Unfortunetly Samsung apk was crap and I lost data for one of my applications. Any idea how can I recover database.db file from internal storage? None of the applications I found could recover .db files just images and documents. Please help and advice
