So I have an iPhone 4S that I got brand new a year ago, but this has never happened until around a month or two ago. The phone's sound will be on, but will randomly make this short, unfamiliar, bubbly, ding-notification-type sound while also vibrating shortly. I'd unlock the phone and check for notifications, but nothing would be there.
I don't have any unusual apps for anything as far as I know, and the phone isn't jailbroken. What is the sound and where is it coming from? I don't have a virus or any spyware on my phone, do I? This has only happened twice. Thanks!
