Lumia 920 screen problems

hey everyone, i am new here but i have use the lumia 920 for 2 weeks. i had a really bad experiences. i am holding the third one right now. just wanna tell you guys the problem. when i open the box, the screen is perfect. very clean very impressive. but 2 hours later, i found the top of the screen which close to the NOKIA signature has some blot or dirt ? i dont know how to call it, cause it is so weird. i can clean it by cloth, but once i touch the place with my finger, it is come back again. it is not the finger prints. obviously it is appear when i touch the place and look like different with the rest of screen. anyone has the same issues?? or someone know how to fix it ? i will try to get the pic to make it clear. this is my first thread. thanks
now as you can see the pics. someone help me plz ....:crying::crying::crying:

I HAD THIS SAME ISSUE. check if there is a space between the screen and the body. i returned my phone to nokia (sent it today so probably get to them by monday and they'll tell me the results in a week) about that 'dirt' like thing and the screen gap. take a piece of paper and see if you can slide its edge along the body and the screen. you might have that problem too.
 
Same here, and not only that. After two weeks of usage the screen has developed some sort of fuzziness...ok, I'll try to explain: it looks like pixelated, especially when viewing white content, but actually it's not. It's more like there was some dirt in between the glass and the screen. I'll try to get this one replaced or repaired Quite annoying tho because this is the second time: first the flickering issues, now this other screen bs, maaaan....

hey i just got my new phone today. so after sending it the second time, they just sent me a new unit because they agreed there was a problem with it. i didn't even ask for a new unit. i just called them before i sent it and said that they didn't fix anything. the girl i was speaking with said to write that when i fill out the 2nd repair order and i did. wish you luck man.
 
I know this is a super late reply, but what you're looking at towards the top is evidence that in a previous life, the screen glass had a screen protector attached to it.
The rectangular pattern is from the shape of a cutout on the protector to accommodate for (from right to left): the earpiece, front-facing camera, and the proximity sensor. As this area is exposed, it is likely that any oleophobic coatings were damaged or worn off.
