I WILL CREATE A MORE IN DEPTH LOOK AT THE SCREEN BEHAVIOR SOON! I have the Galaxy S3!!!! And I am going to be testing the crap out of it! Check out my findings about the display: clipping, shadows, and color calibration!
Samsung has improved from the days of the off shadows on the Galaxy Note. Clipping is not entirely fixed but the screen is acceptable for watching movies.
We await the magical workings of Supercurio to take care of the rest!
