Ok, so it's not really a beep, but I couldn't think of another way to describe it in one word. What I'm hearing every once in a while during a call is the sound you'd hear if someone on a land line would press a button on their phone during the call. Is anyone else having this issue? I know I've had phones in the past that will beep every x minutes during a phone call, but that setting could be turned off. I KNOW I do not have a call/text/etc waiting when this is happening, or any other update, etc. from an app. Am I missing something that would correct this?
