Am using Samsung Galaxy with Android 11. Inspite of my best efforts, its impossible to use Call Recorder. It simply refuses to record Voice calls. Something must be done on warfooting from your side ...... 26/02/2022: Offlate this App has become redundant as it's not stopping Spam Calls & expecting me to tell it that the received call was a Spam. I think you don't have the required database to stop a Spam Call. More over it's not possible to record any conversation on my Samsung Galaxy M30.
