I'm aware of the "fading in the sun" issue that others have reported, and I've also experienced it, both with the K2 that I had previously, as well as the 505 I have now. But over the weekend my 505 started showing a distinctly faded text while I was reading
inside. I just had the regular light on in the living room (not full-spectrum or anything strange) and everything was fine. Then I hit the page-turn button and the next page had lighter text, like the sun had been on it. I paged back, to see if the page that had previously been fine was affected, and it, too, had the lighter text. This went on for about 15 pages, then the text returned to normal. That's been happening off and on now ever since.
Any ideas? The battery was showing 2-3 bars while this was happening. I'm charging it now to see if it also occurs with a full charge.
Thanks.
