January 31, 2019 - The most current software update from ATT for the Note 9 no longer records the other side.  It worked perfect prior to the update.

Android Version: 9
Baseband Version: N960USQU1CSAA
Kernal version: 4.9.112-15119493


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.


Will we be able to use if we root the phone ?


After root the phone, Galaxy Note9 variants with the Qualcomm SDM845 chipset inside can be fixed at once. However those variants with the Exynos 9810 chipset inside still can't be fixed. The good news is, we'll release a new version of Boldbeast Recorder soon that can fix call recording issues for all Android 9 phones with root.
