I am having trouble using BoldBeast with new LG Phoenix 3 (Android 7, M150). I do get some recording both ways, but it's garbled and in and out. I've tried some of the settings listed for other LG phones but without success. Glad for some help!
LG Phoenix 3 uses the Qualcomm Snapdragon msm8909 chip inside as many other phones in the market, other phones don't have the "voice is garbled or distorted" problem, so in theory the problem is not in the phone.
I guess you enabled "HD Voice", most possibly this is the cause of the problem. Previously some Nexus 5X users had the same problem, they fixed it by disabling HD Voice. Please try to disable HD Voice and test again.
Thanks! That seems to have done the trick.
