I have a theory that the defective screens lose the static charge that holds the ink particles because of the UV radiation. Window glass blocks most of the UV wavelengths.
I had the problem pretty badly when I was visiting Phoenix sitting out on my IL's patio. Nearly unreable unless I shaded the screen during page turns.
Sitting in my sunniest window here in MN, it's not a problem, but then it's barely detectable if I take it outside here, either, and it was pretty sunny out today. However, it did show that a window cuts the effect to some extent. I asked for a replacement, I'm not waiting to see if it fades enough to be troublesome come August when I'm enjoying our brief warm weather on the pontoon boat! I didn't have an opportunity to try it in a sunny Phoenix window, as my IL's house has ginomous overhangs so there's never any direct sun
