Random Notification Sound when Laying Phone Down

[SamWitwicky217]

Starting a couple months ago, my phone occasionally started making a sound when I lay it down flat. This 2-note notification sound is not one used by any app I have, and it plays regardless of if I've locked the screen or not. Having no apps open does not seem to prevent it. 

Does anyone have any idea what might be causing this?

You can use Good Lock's Nice Catch Module to show a list of applications that made a sound.

Thanks for the quick reply. I'll check that out.

For those curious, it was NFC making the sound. I didn't know what that was, but after a quick search, I'm quite certain I didn't want it on anyway. Thanks again Pianodude58.
