Moto E / Moto E 2nd phones don't need root, just install Boldbeast Recorder and use following settings to record calls:
- Record Mode: 1, 5 or 7
- Record Format: WAV or 3GP/MP4/AMR (WAV is suggested. Some phones don't work with 3GP/MP4/AMR)
- Tune Audio Route: Group3
Supports Android 4.4 and 5.0.
If possible please upgrade to Android 5.0, it works better than Android 4.4.
