[Galaxy Note 3 General] stanzlavos:
1) I have seen the issue on all my phones. All of them were un-rooted and on stock ROMs. And on the last one I had, I saw the issue right out of the box as that was the first thing i checked. :) Anyhow, I would give it a go (a or b) once I have the next one. :)

2) I have already mentioned in one of my earlier posts on another way to reproduce the issue. I had also posted a video of the same. :)

3) As i already said in one of my earlier posts, after seeing the same issue on that stranger's Note 3, I assumed that this issue was with all SM-N900 and decided just to ignore the display issue and move on. But, the main issues that were still haunting me were :

a) The fact that I couldn't see the same issue on all the N9005s I checked. (LETS IGNORE THIS ;))

b) With 4.4.2 my games started to lag after around 5 minutes of gaming. It was very much visible. It starts of smoooooothly but after around 5 minutes of continuous gaming it just lags (Has bee reported by others as well after moving to 4.4.2 and I think someone had given an explanation for ti as well. Will try it out after I get the new one and rooting it). And once when i tried getting out of the game, I got a split screen. The right end of the homescren wrapped around and a part of it was on the left side. It was actually pretty fun to watch. ;)(This has also been raised by many others) (LETS IGNORE THIS TOO ;))

c) My screen is getting marks easily. Not scratches, marks. The last one got marks because of the Samsung Flip wallet I was using in 4 days !!! It supposed to be Gorilla glass 3 !!! I have used a Galaxy S3 before and I took care of that like my baby just like I took care of my Note 3. It did not have a single scratch after I used it for a year and a half !!! If you really clean it, the marks goes away, but as soon as i start using it again, it reappears. And as i said before, if you take a small drop of water and rub across the screen with a finger, the water would align perfectly along the mark showing that there is in fact some imperfection on the screen there.(This has also been raised by other people I think) BUT THIS, I CANNOT IGNORE !!! I HATE USING SCREEN PROTECTORS BUT LOOKS LIKE THERE IS NO OTHER WAY THIS TIME !!!

And again, the display issue on just the phones I got and some strangers phone I checked ? And all the phones I had got marks - the first one had right out of the box... the second one got it from a pouch I was using.... the third one got it from the flip wallet. Again, random bad luck on just my phones ?

Cmon....!!! :D Anyhow, thanks all for the help. I think I will just leave you guys in peace. :) I did spend a lot of money on this and the feeling that I am being cheated is actually eating me. ;) That was the only reason I put this post on XDA to see if there was anyone else having the same issue. Guess, its just me and my "bad luck". :D

But I am sure that you can't say that Samsung is not cheating(in one way or the other) their customers by actually displaying N9005s and then selling them SM-N900s. ;)

Anyhow, thank you all for all the help. And we can stop discussions on this topic. :)

EDIT : I forgot to mention one small thing : the first two phones with all the issues were on 4.3 out of the box. The last one I got with all the issue was on 4.4.2 out of the box (I luved the phones performance with the KItKat update though. Felt really smooth, and that is one of the compelling factors making me want to get the Note 3 again.). :)
