FA&Q
Q: Why the app doesn't support record internal sound?
A: Android doesn't public API to support 3rd party app so the MIC is the only way. But from Android 10 you can choose Audio source is Internal sound in the app's settings.
Currently, no more apps and games supported for Android 10. This depends on other developers, not me. More info: https://developer.android.com/guide/topics/media/playback-capture

Q: Why the app can't record a call, Whatapps, PUGB or other apps that use the MIC?
A: Two apps can't use the MIC at the same time. It will conflict hardware so you need to turn off the feature "Record sound" in the settings this app.

You must go to security -> choose permission -> permission -> Screen Recorder and turn on pop up window. Follow up, you go to security -> Permission -> AutoStart -> turn on Screen Recorder.
