Xiaomi Redmi 9 do not record the callers voice can not hear caller in play back
If your voice is good but the voice of your friend is weak or silent in recordings, you should
- Switch on the loudspeaker during a call, so Boldbeast can record the call on both sides normally. Or
- Root the phone, so Boldbeast can fix it completely to record calls on both sides perfectly without switching on the loudspeaker.
