On my freshly hard reset iPhone 4 (iOS 7.1.2), when I record a voice memo it does not show up in the Recordings.db database.
The database itself is present and well formatted but the ZRECORDING table stays empty. The recording and playback work perfectly well though.
Tested on another iPhone 4 running the same iOS version, it works as expected (ie a new entry is created for each new voice memo with timestamp, duration and path)...
Am I missing something here or is it a bug?
