Im having this problem with my brand spankin new phone.... i noticed this issue the day after i got it just decided to still stick with the phone ANYWAYS it seems that when you lower your brightness put on a black wallpaper and go into a completely BLACKED out room you can see black spots on the screen, its not noticeable on regular use or if you have your brightness up at night, it only appears if you recreate those conditions i stated earlier......... i researched a little and it turns out its a issue with HD Samoled screens so not only the s3 has this issue but also the Galaxy Nexus...many people on those forums exchanged the phone but ended up with more or less black spots, so i decided since theres no point in exchanging (cause i'd probably get more black spots) im just going to stick with it. Its not really a big deal because it isnt noticable unless im using my phone in bed.Anyone else have this issue? try going in a blacked out room and rebooting your phone and when the white text SAMSUNG comes on the black background look around for pixels that are darker then others!

You paid Perfect Money you need a FLAWLESS screen..........Your $$$ wasn't wet, or damaged, or returned when you paid it was it???? LOL.....My point exactly! Case closed....Lol
You guys mention spots. I got streaks some thinner than others on the right and left side running horizontal. From the descriptions I've read it sounds like its a bit more extreme than the "spots" mentioned.
I had streaks also and called sprint and told them about my situation, a. Few minutes of twisting the reps arm we came to an agreement that since I was still within my 14 days sprint would send me a BRAND NEW unopened galaxy s3 heck they even asked me what color I wanted lol anyways they sent it to my house with one day shipping, the new device has 1 tiny dot but that is way better then the 3 huge streaks and few dots my old s3 had..
P.s. they will tell you that you NEED to come in to a sprint store to check it out, B.S. they just try and go through every option to not have to send you a new device, just say "I don't have transportation and the nearest sprint store is miles away can you send me a replacement unit?" I have used this line countless times works like a charm
