On my iPod touch 4g beside the back camera what is that dot!?!?
Its not a flash! or a microphone! It is a light sensor so if you go into a dark spot somewhere it brightens up the screen! You can control this in your brightness settings.This is proven on the apple website.
That dot on your iPhone 4 next to the camera is your flash. If you go to take a picture turn the phone around and you will see the flash go off.
The dot is the flash
On the iPod touch 4, the dot next to the back camera is a microphone...not a flash. The iPhone has a flash, not the iPod. :)
I agree with sastill it's just a microphone not a flash.
