What is the Call Recorder App or what is a good call recorder app? They are used to record phone calls, but some phones do not support in-line call recording, so instead would record from the phone's microphone. The main audio format used to record phone calls would be "amr", though some apps allow other formats such as "mp3" or "wav". Some formats would slow the phone's performance or can create recording issues. If you wish to use a different format, then you can always look into getting a media converter app on your phone.
You may have to try a few of these types of apps to find one that works with your phone. I don't know why but they seem to be more specific to phones that others. Also they require tinkering with the settings sometimes especially in selecting the audio source like phone call or microphone. If the source is microphone you only get the part of the conversation on your side. This is why you want to test several apps before you really need one to work properly every time. Some of the apps I have tested and worked with my Samsung Galaxy Note 2 are as follows.
