Turns out, to get a (barely but still) visible picture of my phone's LCD screen on a crappy camera, I had to tinker with options I had no clue about. Tried to change the "White" adjustment, didn't work. Tried changing size and quality, didn't work. Finally I tried turning down what I probably should have tried first: exposure. My guess was less exposure = less time for light = less wash out. I was right when I found out I could go less than the default 0.

So there's my mobile phone, my mobile wallpaper (the clean version, which is posted on DA), and something attached to my phone? Huh...
