Hi, I got my kindle touch probably 1 year ago. I read that kindle sometimes has shadows of previous pages and therefore I set the screen to refresh every page turn. I left it on my drawer for sometimes because I moved and live with my new wife. I was surprised that when I opened it few weeks ago, it got faded on the bottom (I cant see the page number and half down the screen looks faded) and the shadowing did not refresh the screen accordingly. Anyone has this problem?
