I have the following setting:

Recode mode :1
Record format: mp3
Tune audio effect: off
Tune audio route:3

But I can only hear my voice in the recording. The other side is not audible.

What should be the setting for my phone? Thanks.

You said "I can only hear my voice in the recording", so root is the only way to go.

If you don't root the phone, you have to wait for the manufacturer to fix it in future ROM updates, because no other solution available.

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