I've had this K2 for a little over 2 years and over the weekend, this odd gray smudge appeared. It has not been mishandled and this is the first trouble I've had.
One day over the weekend, it wouldn't start, no matter what I did. Even though I knew it wasn't low on battery, I plugged it into the charger. A minute later, it came on and suddenly had the smudge. I've restarted it and it will not go away.
It's kind of small, but still bothersome because it is right in line with text. Has anyone had this issue before?
