How do I find out what other app is using my mic so my call recording app will work again on LG

[Android Central Question]

I have an LG and download ed call recording app. It was working great until a couple days ago... When I make a call it says that app can't record calls because the mic is being used in another app... How do I fix this???

Welcome to Android Central! Which LG phone? Try going to Settings>Apps, tap Menu, then Reset All App Preferences. Does it work now?
