The T-Mobile version of the Galaxy S II has already solidified itself as one of the best smartphones ever to grace the Magenta network and our review of it was glowing. Unfortunately, there seems to be, at least for some users on XDA Developer Forums a bit of an issue with the Super AMOLED Plus display. The XDA thread takes an in-depth look at the panels on both the T-Mobile and Sprint variants and ends up with some surprising conclusions. The results shows a noticeable difference between the color reproduction and contrast levels as seen in the pictures at the end of this post.

Along with the aforementioned problems comes word that lines and blobs pop up when the phone is viewed with the highest level of brightness available in a dark room. Fortunately, the T-Mobile model isn’t alone as the problem can be duplicated on the AT&T Skyrocket as well as the Telus and Rogers versions of the Galaxy S II.

As it stands, the conclusion by the original poster of the XDA thread who performed the tests is that the T-Mobile version, along with the AT&T, Rogers and Telus variants suffer from poor screen calibration. The thread itself has extended to 27 pages full of users, many able to duplicate the problem. While not every individual phone appears to be affected, for some it is a real headache. We hope that Samsung takes note of the issue and that it can be solved with a software fix sometime in the near future.
