We are the developer of call recorder, thanks for the comment,to record calls you must always:
- have data or Wi-Fi enabled.
- on audio source -> Auto 3v on audio sample rate -> 48000 Hz 4v
- on bitrate -> 320 Kbps 5v
- on Increase recording volume: -> (BE ALL THE REAR, FULLY CLOSED , OTHERWISE IT CHANGES THE AUDIO)
The best call recording app
