Dear Sir/ Mam, I have paid version for Samsung S9 plus of boldbest & I’m enjoying same. But 3 days ago Samsung released new software version. When I installed new version in my phone, during call recording my voice is clear but caller’s voice is very weak.
Kindly sort out my problem.

Android 9.0 disabled the call recording feature. This is the reason why your own voice is good but the caller's voice is very weak in recordings. No matter what recorder you are using in the market the result is the same. You can test and confirm this fact.
Boldbeast Recorder can fix the problem if you root the phone. Without root there will be no solution in the world unfortunately.
