This version does not support all Android devices (9 / Pie) … (Unfortunately, Google has blocked the ability to register another face under Android 9, therefore, most devices not supported until now we are trying to find a workaround on our side.) For Call Recorder to work properly, follow the on*screen instructions once the installation is complete.
