So now I get to treat my device with utter disrespect - no worries about sand, scratches, sun lotion on it - I am getting a new one in September.
Yet, no reading under direct sunlight either.
Anyhow... I just figured I'd share...
A lot of e-ink screens have this issue. At Kobo we weed these out by shining a really bright light (I believe it's 20,000 lumens..?) on the screen before it joins the board assembly.
Interesting story, in the early days we couldn't figure out for the longest time why the sun-fading was happening. We tried ultraviolet light and I personally even tried to heat the screen with a lighter to see if that was the problem lol. Finally found the issue.
Sometimes however, a screen or two will slip through the cracks (although we have not had a return yet for that reason that I know of).
