I have a Xiaomi MI A3 not rooted, purchased in Italy from Amazon. I have done various tests but I can not hear anything. Both when I speak and when the correspondent speaks.
There are indications on how to overcome this inconvenience, otherwise the App becomes useless.


At first you should update Boldbeast Recorder to the latest version.
Then see [009] in this page http://www.boldbeast.com/android/call_r … oting.html to use suggested settings to record calls.
