Upon the latest updates in Google’s Developer Policy, call recording apps can no longer use accessibility services for call recording purposes. In view of this, we’ve developed a supplementary utility app, - Cube ACR Helper, to enable our users to continue recording calls on Android 9 devices and higher.

So, to review the functionality of this tool, you need to take the following steps:

1. Install Cube ACR (https://play.google.com/store/apps/details?id=com.catalinagroup.callrecorder) from Google Play.
2. Install Cube ACR Helper and enable all requested permissions for this app.
3. Try call recording with Cube ACR app.
