As someone already pointed out, the stuck pixels were green color and some, on my phone, had a slight light green/red hue to them. SO, what I decided to do, it to take a microscope with 100x magnification, and take a look at what this stuck pixel is actually doing! I know you probably think that stuck pixel is a bad one, and does not work, BUT, its is FALSE for the 15+ stuck pixels that I inspected!!! The stuck pixels are NOT STUCK, and they actually DO work !! As you all know, a pixel is a combination of RGB tft transistors positioned really close together. When I looked under a microscope with a phone's screen showing black background (provided in this thread from a zip file) at the three brightest "stuck pixels", I noticed that only about the 1/8 of the red tft and 1/8 green tft emit more light while the rest of the pixel is emitting very low light (that's for the pixel with green/red hue to it. Pixel with green hue had only a tiny part of green tft malfuntion)! So for some reason, a manufacturing defect of some kind, a tiny fraction of the tft transistor (green or red and green) is getting more power even thought the rest of the tft transistor(s) is getting low power and lights up evenly. A good pixel had all of its RGB tft transistors light up low and evenly while displaying this black background. Once I closed the photo album, the "stuck" pixel lit up, and all three RGB tft transistors worked just like the rest on the good pixels on the screen, however I could still see a little bit of uneven lighting on the tiny portion of defective tft. So the only reason WHY you see dead pixels on the dark screen is because while most of the pixel is off, a tiny part of green or green and red tft is lit up more than the rest and you see it stand out. Under normal use, you will not be able to see a stuck pixel unless its really bad, which in my case never is! I also stopped by a TMobile store, and inspected the screen on TP2..sure enough, there were stuck pixels! I think it's just a common thing, so please don't be too freaked out! Remember, you screen has 384,000 pixels and having them all being perfect is nearly impossible. I guarantee you I will find at least several "stuck pixels" for all the users that said they didn't have any in this thread. So, there's my conclusion to the story!
Regards,
Mikhail
Edit, just attacked an illustration of what's happening with a stuck pixel while viewing a dark background. As you can see, most of the pixel is lit up evenly, but a tiny part of green tft or green and red tfts are lit up brighter.
