I've had my Treo 750 for almost 3 years now it seems, and it's been great despite surviving a car crash, left in the rain for days, etc. Recently, I tried taking a photo and I thought the lens was covered or it hadn't loaded the camera yet, because the screen was completely black (it showed that it was in camera mode with 999 pictures left). I held it up to the brightest window and it barely showed the shape and color of where the light was coming from, but it's like my phone has sunglasses on! The screen is still bright as ever and I'm experiencing no other difficulties. I know that in the past, it would automatically use the low light sensor to get better contrast in low light settings, but now I think it's just ignoring everything and thinks its being pointed at the sun 24/7!
