So I have noticed that when I scroll on my HD7 there are black lines across the top of every column - in other words it looks like the screen is lagging slightly behind the scrolling.
It is most obvious when you see it blue on black as far as I can tell.
It seems to vanish with a white background. It is something I have seen on every HD7 I have seen in stores and my own HD7.
It is almost like the effect of when you wave your finger/hand in front of your face and you see a trail.... that is what it looks like.
Is that a screen issue or a human eye can't keep up issue?
I am sorry if you now notice this issue on your new phone
in another thread about this someone said it was due to the screen not refreshing quickly enough due to the type of lcd used, I do know it happens on mine as well though, try setting it to the purple theme, it gets really bad, and if you tilt the phone the theme turns pink which amused me.
One of the first things I noticed about the NC was a faint grid of dots under the screen before turning it on. I also see a faint line making up the grid. Im guessing this is "normal" since its part of the screen. I never noticed this on other devices though. I dont notice it when the screen in on though.
I have noticed this too. It shows if you turn off the screen and look at it at an angle under light.
That is the touchscreen sensor, and is there on every capacitive device (whether or not you have noticed before is another thing)..
Anyone else notice any slight dimming of the backlight around the bottom edge of the screen, as if the backlight doesn't quite reach or doesn't fully illuminate that part of the screen? Mine is very subtle, but noticeable in the bottom-left corner. The average person probably wouldn't notice it right away, but once you use it for a few minutes in an app with a white background, it's pretty obvious. I haven't owned an LCD based device in a few years, so not how common this issue is these days. I wish the OCD part of me could just ignore it.

I've noticed the same thing, it's also more apparent with power saver mode enabled. It was happening to the models at the store as well so I guess it's just how it is.
Folks,
Got a question for you -- as per the title. To give you a little background, I bought an S2 8.0, loved it, and then decided that I really ought to replace my existing "data plan" tablet from the S 8.4 to the S2 9.7. So, good-bye to the S2 8.0, and I've got a new S2 9.7 LTE.
All is well, EXCEPT for some screen oddness. I'll have to post some pictures, but I think I can describe it well enough. To begin with, I don't really like "busy" wallpaper -- I just use a solid-color, medium-to-dark blue wallpaper as my background. What I really notice, both in portrait and landscape orientation, is a darker band at the top of the screen -- again, it happens in both portrait and landscape orientation. It seems to be a "viewing angle" thing, as the dark "top" in landscape orientation doesn't turn into a dark "side" in portrait orientation. Instead, when I move to portrait orientation, then the top of the screen has this dark band, and the sides are just fine.
But I don't notice quite the same thing happening when I get into some apps -- for instance, the yellow/orange top band in the "Memo" application doesn't turn noticeably darker. But the green top band in the "Evernote" application shows it IN SPADES, though it's a really thin band at the very edge of the screen. And, again, it's always at the top, no matter which orientation I'm in, that I see the dark band.
Anyway, that's the most obvious stuff. However, when you back up and take the whole screen in view, what I'm really seeing is A LOT OF COLOR CHANGE as I angle the tablet towards me (more vertical) and away from me (more horizontal). Again, just go into the Memo application, and lay your tablet flat on a table, then grab it and tilt it up towards you -- do you get a big change in color, or does it stay the same? I guess I would say that the "white" color "turns bluish" as I raise the tablet towards me (making it more vertical), and it goes more to a normal white when I lay it flat.
I can understand changes in screen quality due to viewing angles, but that's not something that I associate with OLED screens. I sure didn't see anything like this at all with the S2 8.0 that I had. And I've started looking at S2 9.7 tablets in stores, and I really haven't seen anything like it in the stores. Thus, I'm definitely thinking about returning the thing -- unless it's really a case of "they all do it."
So, if you guys could check out your tablets and let me know if you see anything like this, I would appreciate it. It's not worth taking the thing back and asking for an exchange if what I'm seeing is common, but I'm definitely a bit disappointed in the screen quality that I've got with this tablet.
Thanks in advance for checking this out for me, and for any thoughts you'd like to send my way!

I have yet to see an S2 that can display a uniform white screen. I can always see a light pink/purple tint on a white background. If all you're doing is consuming media you will never notice, but if you're reading anything with a white background it gets too distracting. I don't see any issues with uniform brightness though, it looks perfect from that standpoint.

Understood -- thanks. I installed a couple of screen testing apps, and they show no issues. For instance, I pulled up a full-screen blue that was very similar to the blue I'm using for my background, and it was nicely solid blue. Then I pulled up a full-screen green that was similar to the top of Evernote, and it was nicely solid blue. Then I pulled up a full-screen white, and you could see what you and I have both mentioned -- it does change colors a bit as you move the screen around.
So, it's just very strange what my S2 is doing -- it's like it must have something to do with other on-screen elements. I'll definitely take it back and exchange it for another one, but I'm just trying to get a grip on whether this is happening on any other S2 tablets. And it definitely appears that it isn't.
Thanks for your reply!

I've been checking my T815 a little while ago after noticing similar behaviour. The way I see it, the tab S2 screen is very sensitive to the viewing angle. Not so much in blue and red, but very much so in green. In fact, to get a proper green, I have to look dead on. I even notice a change in the green colour: dead on it's yellowish green, while even at a slight angle it is an uglier green. The first is clearly what the device is calibrated for, because that's when things like skin tones look perfect.
I used the *#0*# menu to test.
I compared this to my other devices. On the note4 I didn't notice this. But that may be because of the smaller screen. On my previous tab, tab77, the effect was also completely absent. But that one has a completely different oled layout.
I've already eliminated display modes and auto brightness as influences. I still have to look into the effects of ambient light, since the displays of my devices do reflect differently when turned off. In fact, under some angles the tab S2 reflects a bright white lamp as pure green. While the tab77 always reflects the same lamp as white.
I know that the tab S2 has an rgb matrix that has two Gs for every R and B. That's probably related to the effect I'm seeing.
Hi guys,
I'm experiencing screen bleeding issue on the left edge, with dark mode on. I'm able to notice that whenever opening Youtube app (with dark theme) specially during night time. Is anyone else experiencing this?
Typically I've heard of screen bleeding in LCD screens. Surprised to notice that on an AMOLED...
Does it have like a little slit at the left side when properly place under light? Mine has. So worried a little splash of water can go inside.
