BTW, who knows: constant light gray stripes on gray background - is that covered by warranty? seem to be some damaged/worn-out rows. It is not software issue, 100%.

"Screen Adjuster" from the Market does much the same job, and works on ICS.
It's free, but it needs restarting after a reboot, and the changes don't show when you're in a hardware decoding video player (like MX Player).

I had an S3 for a while, and HD videos looked fabulous on it and crap on my S2. I thought it was a hardware thing, but I switched from Rockplayer to MX player (with HW decoding disabled) and jacked the red up 10% using Screen Adjuster and got the playback looking identical (only smaller, obviously)
I was happy to send the S3 back after that.

The app is old and beta, it has some bugs and you may need to reflash your rom to go to stock.

I don't know if I've do something wrong... but I've decompiled the Soft Screen Tuner.apk and now I've the source code.
But I'm not a developer and I don't know how to modify this AWESOME app for do it compatible with ICS!
If I can I do an attachment with the source code... maybe any developers come here and help us...

@For the author of this FANTASTIC app: If you do this app Pay in the market I'll buy it! and I think a lot of people buy it! you'd can be a very rich man! lol
