No matter how much we call ourselves a pro in using and understanding iPhone, there are many things we still don’t know about it. Today I came up with something we notice every day in our iPhone, but we are still unable to figure it out.
Have you ever wondered why do we have a small black hole at the back of our iPhone between camera and flash? Do you think is it a reset button or something?
The answer to your question is that in the picture of iPhone 6,6s next to the camera lense and the flash light you will find a dot which is actually a microphone and is used for dual purpose.
You will find this dot like structure only in the iPhone 6,6s as they are made in keeping in mind of the issues of noise in the background and the speaker quality when you are doing some video or musical stuff on your iPhone .These you won’t find in any other previous generation iPhones as they don’t have this technology system.
This small hole is basically a microphone which helps to record voice more clearly while you are recording videos so that during high resolution video you may get a crystal clear voice with proper effects while you play it on HD video compatible devices and TV.
