variable of measurement, do you notice the difference between them?
Yup, one of the picture had a mistery gradient built in the picture.
While the other pic does not have it. To us N97 user, might find it
annoying. Especially when we want to snap something in low light area.
This white gradient appear when the flash enter the plastic that cover
the lense. A fine tip sharpie will do the trick for us.
Swipe your finger around the flaash area, you'll find a bit of
leverage around the corner. Use the sharpie and mark 'inside' the
leverage area, and now it's done.
Give it a try, any question or comment are welcome.
