Until a few years ago it was easy record phone calls secretly on Android, but if you own a smartphone you will have noticed that now it is much more complicated, sometimes impossible. Due to European legislation, mobile phone manufacturers can no longer include a feature in the operating system to record phone calls received on Android.
The speech also applies to the most important giants such as OPPO, Realme, Xiaomi and Samsung. Although there is no dedicated functionality in the ColorOS and Realme UI, luckily it is still possible to record a phone call on OPPO and Realme smartphones. It makes no difference if Android 11, 10, 9 Pie or other versions are installed on your phone: for now it is possible, but only by using a specific app to record incoming and outgoing voice calls compatible with the smartphone you own.
In this guide we explain how to record calls on OPPO and Realme smartphones automatically in the best way, without root or any kind of program and above all for free. We have tried this method from several OPPOs including Find X2 Neo and Lite, which is why we are sure about its effectiveness, but not being able to test it on all smartphones we do not guarantee it will work with all terminals.
