T989 Screen issues.
I upgraded to the T989 Galaxy S II and found the same issue on it. You will notice that the backlight isn't right. It's brighter than it should be - gives a fuzzy glow. There are also black blotches on the screen...all over it actually. Enough to annoy you when you are trying to watch a movie in the dark. I returned that one thinking ok maybe it's just that one. My second one...SAME ISSUE. Even worse this time...there were verticle lines running top to bottom. Quite visible lines.
On the first return, the Tmobile reps compared my T989 with my i9100 while viewing a blank black screen (can be produced by taking a photo with your phone against your jeans or shirt then viewing it in full screen). They confirmed the issue to be true.
On the second return, other Tmobile reps also compared the T989 with my i9100 and confirmed the issue as well. One rep had a T989 and hers also had the issue. I then checked the store display model. Same issue as well.
If this is something you can live with, then just keep it. It doesn't seem to happen clearly if you turn your brightness above max or don't watch movies or use the phone in the dark.
There is a significant color difference between the T989 and i9100. The color of the message bar was compared between the two. The i9100 showed a true blue while the T989 had a faded/greenish blue tint to it. The difference is noticable in any brightness. Keep in mind that both phones have SUPER AMOLED PLUS screens.
I'm assuming all the T989s have this issue due to the manufacturer having messed something up during production.

ase do not ask me to run any test on the T989 for I have since returned it to the store and will never buy another T989. I'm sticking with my original i9100 Galaxy S II.
