Sprint & T-Mobile Samsung Galaxy S II screen problems
Reports are coming in via customers that their T-Mobile Samsung Galaxy S II displays are experiencing screen problems. It has come to light that SGSII users are having issues and a couple of forum threads going into deep detail about T-Mobile and Sprint variants of the smartphone.
XDA Forums have two separate threads talking about these issues, one talks about how you can reproduce screen issues, updated 3x results of detailed testing (some phones), and the other thread looks at comparing the screen quality against Sprint SII (XDA 1 — XDA 2).
In a nutshell there are problems with colour reproduction and contrast levels, a few customers have come forward reporting that they have had blobs and lines pop up, this is occurring when viewing the screen with the brightness turned right up when in dark rooms.
Developers are looking at a fix for the above issues, so be patient if you are having any screen problems. Please try out the simple test below, it basically allows you to reproduce the simple test.
1. Download the blobs.jpg to your phone. A copy of blobs.jpg is attached here. Or simply point the browser on your phone to: http://cheema.com/blobs.jpg Tap and hold the dark gray rectangle and then select “Save image” from the menu. Note that it is not entirely black. It is dark grey. Testing with a black screen gives you false hope that your display is good.
2. Turn off automatic brightness and dial down the brightness all the way to make it as dark as possible. Go to Home->Settings->Display->Brightness.
3. Open up the “Gallery” application and locate the blobs.jpg in the download folder and view it in a mostly dark room.
