why does my samsung galaxy s7 make random sounds

[rfarke2]

for no apparent reason, it will make part of the sound it makes when a text comes in.

Welcome to Android Central! No new notification icons? Does this happen if you turn off NFC?

I moved this from the Oreo forum to the S7 forum, since this is unlikely to be a general Oreo issue.
