my Galaxy s6 is making a noise like a phone call being dialed

[AC Question]

Along with this problem the screen will flash maybe 4 -5 times a minute.I can not tell if it is making a call.

Welcome to Android Central! Does this happen when you're trying to make a call, or at random? Can you record a video of it happening and post it to YouTube or a similar site so that we can see what it looks like?
