I had whatsapp chat open on my iPhone 7 when suddenly my phone started to make the sound it makes, when you take a burst picture, The camera wasn't even open. I had to turn my phone off to make it stop! It’s strange because my phone is in perfect shape and it has only happened that once.This is very concerning to me that my pictures were taken without my consent! Can somebody please help me understand, I haven’t found anybody else’s that’s experienced this.
