My iPhone 4G keeps calling itself?

I don't know how, or why but my iPhone keeps calling itself? I answer and it says in an automated voice "are you still there? Press 4 for personal options, press 2 to disconnect and it does nothing" wtf! It's creeping me out. Anyone else having this problem?

You need to update your iphone software!

Yes… I'm having the same issue and my software is already updated. What is going on?

  • What to do if your iPhone 4S keeps going off by itself? My iphone keeps going off by itself and turning back on by itself. Like if I get on one of my apps, my screen turns black and goes off by itself and turns back on. I tried resetting my iPhone 2 times but it still does this. Can someone please help me with this because its so annoying.
  • Unknown caller keeps calling? Me and my friend were prank calling In N Out and McDonalds but we didn't talk, we just made random funny noises and hung up. A couple minutes later I get a call titled "Unknown." I didn't answer. Yet all night that person tried calling me. Any advice? Am I in trouble? I'm using an iPhone 5 with iOS 7.
