Why did my iphone 5s make a random noise?

So today i was playing a game with all the noise off and out of no where i heard a thump noise from my phone speaker. At that time i had my noise up all the way and i don't think it was from the game because i had all the noise off. It sounded like a table thump like how you would hear over skype sort of. Also sometimes when i leave an app there's a red bar on top like those ones you have when you skype someone or call someone and then like less than a second later its gone. I don't know if these are glitches or not and i'm scared someone is stalking my phone. Its a iphone 5s and ios 8.4 and it use to be jail broken but its not anymore. The red bar happened during jail break and the noise happened when it wasn't

Oh. That's from the e-mail notification.

There's a cat inside your phone.

I don't know

  • Why iPhone s earbud make loud buzzing noise? When I was playing music on my iPhone 5s using its earbud, suddenly it makes a loud buzz (nearly killed my ears). At first, I thought it was my phone, but when I unplugged my earbud, the sound works fine. And then I thought my earbud was the problem but when I tried to restart my iPhone, and plugged in my earbud, it works! Happened for a few times and I still don't know how and why it happened.
