According to official posts by both ACR and Boldbeast, call-recording won't work with Android Pie: ACR: https://bitbucket.org/copluk/acr/issues/2418/kb-android-9-p-call-recording-issues "We would like to inform our users that there will be no call recording workaround on Android 9 and above. No 3rd party call recording app will be able to do so." Boldbeast: https://www.boldbeast.com/android/call_recorder.html Now many users have upgraded to Android 9.0 Pie, please be noticed: In some countries a few Android 9.0 phones have the call recording feature enabled, so no root needed, Boldbeast records calls great. In most countries most Android 9.0 phones have the call recording feature disabled. In recordings your own voice is good but the caller's voice is very weak, no matter what recorder you are using. In this case you should root the phone then Boldbeast can fix the problem perfectly. Without root you have no solution in the whole world undoubtedly (you can test and confirm the fact yourself), with root Boldbeast is exactly the solution. So, bye bye Android Pie!
