" parts of my recording become silent!
Some devices turn their microphones off*when their screens go off, and Easy Voice Recorder cannot detect this on every device. For these devices, you will need to force the screen to remain on while Easy Voice Recorder is recording. You can do this by going to Settings->Advanced and setting “Keep awake while recording” to “Allow dimmed screen” or “Leave screen on”
