You're not alone.

I got my N9 on Saturday and noticed the pink fringing on white text and the left edge of a white panel straight away. Sadly that seems to be an issue with pentile AMOLED displays just not being as good as RGB panels. It reminds me of Windows text anti-aliasing. I stare at Mac screens most of the time with occasional switches to Windows so I notice these things. I would hope it could be tweaked though. MacOS on the same panels doesn't have the same issues Windows has so it can be alleviated with software obviously. To me it just looks like the sub-pixel rendering algorithms need a bit of a tweak.

The black spots on dark grey screens I noticed last night watching a video in a dark room and then discovered this thread. I've got a black line about 4mm wide stretching about 2/3rds of the way over the screen about where the volume buttons are. I've got two parallel lines about 4mm wide and 2cm long in the middle of the screen toward the right edge. I've got another blotch near the bottom left of the screen. I only notice these when displaying something dark grey in the dark. I was playing Tron (the movie) on it so you can imagine how distracting dark splotches are on a mostly dark grey movie. (As an aside, the movie player skips frames all over the place on movie files that worked great on my C7 - hope they can get a better performing codec sorted)

The black spot issue is obviously a manufacturing issue and it's very, very disappointing. I don't notice it 99% of the time but I know it's there. When it's such a beautiful and expensive slab of technology, little flaws are not acceptable. If I wasn't enjoying the phone so much otherwise I'd send it back. I figure I'd give it a while to see if Nokia responds to this issue and fixes it in a later production run. Seems pointless getting a replacement just now if it comes from the same production run. Surely they're going to have the same issues with the Lumia 800 which shares a similar screen?

The automatic screen brightness adjustment also seems to have a life of it's own. I hope that's fixable in software also because it does ramp up and down a bit too aggressively.

Love the phone and OS but I'm somewhat disappointed by the screen.
