Samsung Galaxy S3 SGH-T999 doesn't need root, Boldbeast Recorder works perfectly. All other recorders don't work, right? This is the only solution in the world without root.
Please use these settings to record calls:
- Record Mode: 4
- Tune Audio Effect: No
- Tune Audio Route: No
- Tune Samsung1: Yes
- Tune Samsung2: Yes
- Tune Samsung3: Test Group1, Group2, Group3, Group4, Group5, Group6 one by one
It records calls in two directions loudly and clearly.
