unfortunately Samsung has blocked call recorders from working on one of the updates at the beginning of 2020, and all modern samsung devices such as Galaxy A10, A20... S10, S10+ Note 10 note 10+ and so on that have been updated stopped working. Galaxy S20 not yet, but it will, they are waiting people to buy it, and after before launching galaxy S30 they will also block. Why? I have no idea but I and everyone that owns a Samsung feels this measure as a lack of respect and consideration for their customers. My advice? Try considering another brands. Don't forget to talk bad about the brand as this is the only way they will start bothering about their customer's opinion.
