You can Also Record Phone Calls using an App.
Outside of the camera app, your Android device can record more than just what’s on the screen. You can also record your phone calls, but this should only be done with the permission of the person you’re speaking to. Downloading an app is the only way most phones have this capability because it is not included by default.
Call Recorder – ACR, fortunately, is an Android-compatible option. There is no need to worry about it once it is installed because it will simply run in the background without interfering with your work. By clicking on a person’s name, you can listen to their recorded conversation. Sharing and deleting everything is also possible from this page.
