Hi, I have just received my Nokia 5610 and everything is great except the most bottom row of keys do not light up as bright as the rest and the screen has rays of light at the bottom edge of the screen. I say "rays" because there are light spots and dark spots so the light coming from the bottom isn't evenly distributed. It is especially noticeable when the screen is mostly white, such as when the phone powers up and the Nokia logo is displayed. Is this normal?
