Hallo,
I have just installed your call recorder with Mode 12 and Hotkey adjusted.
I can hear my voice perfectly, but the voice of the other person very week.
Could I hear the voice of the other person better? If needed , could root my phone.
Thanks in advance.

If your voice is good but the voice of your friend is weak or silent in recordings, you should root the phone then Boldbeast Recorder can fix it. Without root there is no solution on the whole market unfortunately.
