My iPhone 4 started randomly making beeping noises?

I just was sitting in the car and my mom said, "What's that beeping noise?" I listened closely and couldn't make it out. Later we heard it and I put my ear up to my only working speaker. I heard it beeping. I saw the silent button the side of my phone was pulled to the left so you could see the orange mark. I pulled it forward and I thought I still could hear it… Help!

Are you sure you were't just hearing things? It could have been an alarm clock, notification, ring, or something else. I have never heard of that before on an iPhone.

  • My new iPhone 5 keeps randomly beeping and vibrating? I got a new iPhone 5 for Christmas and it was working perfectly fine for a few days. But then it started acting up. I usually have my phone in my back pocket and then one day it just randomly beeped and vibrated and I thought it was a text but it wasn't. It wasn't even a notification. So I have no idea what is going on or what is wrong with it.
  • My iPhone 5c randomly started to turn off but then turned back on? I was playing on my iPhone and then it went to the apple logo as if turning off, so inassumed it had died, and I was about to plug it in when it turned back on and my battery was at 86% still. It scared me because I'm a already a bit paranoid as my door randomly opened earlier, so with my iPhone being weird on top of that I'm a bit freaked out, are there any logical reasons on why it did this? I've had the phone for 2 months and it's never done this before
  • My iPhone 5 screen started making this clicking sound when pressed on? It sounds like the home button screen "pop" when clicked. It's on the top right and when it's pressed on it pops. If I take it to Apple will they replace it for free or give me a new one? I bought it through verizon and I'm not sure if I still have guarantee thing going on.
  • My iPhone (3GS) randomly started playing a song and turning voice control on today? Today, when I was in second period at school, my iPhone randomly started playing a song from my library. In third period, while doing an assessment, voice control turned on. At lunch, I turned my phone off and took it out of my back and put it in my inside blazer pocket. It might be a new bag I started using today that caused the problem. I really want to know how to stop this so I can stop worrying. (;
