The call recording feature of LG G Stylo Android 5.1.1 is disabled by LG. You must have found without root all other recorders can only record your voice, the caller's voice is very weak.
The good news is, Boldbeast Recorder can bypass the limit set by LG, it records calls perfectly in two sides, No Root Needed, just install and go.
Thanks to Bob Sharp, he told us following settings in the app works well for his LG G Stylo LGMS631 phone:
- Record Mode: test 1 and 6
- Tune Audio Route: Group3
