MT2-L03, Android 4.3. Recording works on phone with speaker turned on.  Does not work with bluetooth headset (only records my side). I had it set to automatically turn on the speaker, which works for the phone, but sometimes I want to use the headset.

Thanks.

Your phone has the Qualcomm MSM8928 chip inside. There is a bug in the ROM of your phone related to bluetooth recording, no matter what recorder in the market you are using the problem is always there.

Boldbeast Recorder can fix the problem. Please root your phone, enable the "Change Audio Control" option in the app, then you'll record calls perfectly in two directions via bluetooth. The option is visible only after you root the phone.
