Does anyone know what that is and what it is for?

Have a look at this picture of a Sony Ericsson k750i

On the back near the camera lens towards the top, there is a small semi-circle like thing that you can take out and put back in...does anyone know what that is for?

No no, not the mirror, i know what that is, its the other thing that near it!

I was wondering that too, its not in the manual anywhere and there is nothing in the box that connects to it. I though it might be where you could plug in a flash booster but thats just a guess

Shan't!

iT LOOKS LIKE IT COULD BE A LENS CAP.

yep

all i can see is the camera lens, the flash lens, and a circular light

looks like a flash

ITS FOR A MIRROR WHEN YOU TAKE A PIC OF YOURSELF

Could be a cover for an external antenna connection, for car fixing kits.
