My 2 month old W810i has an icon on screen when in camera mode which looks like a little box with lines above and below it. It appears just to the left of the word "settings" i have looked through the manual and all the available options on the phone but cannot seem to find any reference to it.
I have two W810i's and my other one does not have the same icon on the screen and appears to handle light better when looking through the view finder.
