If your refering to screen smearing than yes it is. Its also well known and has been talked about quite a bit in these forums...like when your in a hlack background with white text and scrolling

Does it have gas in it? If not, try to reboot it.

Green kinda hue on the screen

Has anyone noticed a green hue on the screen, its only just noticable.
I've got my note set on maximum brightness and i only notice it on some apps that i'm using.
Take using the XDA app. When scrolling thought the threads and forums i notice that the screen takes on a slight green hue when i stop scrolling and the when i start scrolling again the screen turns white again.
Is this a known issue or could it be just my note? Can anyone else test this and get back to me with your results and opinion please.

I do have exactly the same feeling on XDA forum pages when scrolling, and more generally a green tint... Slight but there... (And I had two Notes so far. The first one exchanged because of grey shades on the screen and the second one slightly greener than the first one). An I'm sure there isn't two screens alike...
I also noticed a big red splodge when using my camera. It was in low light n i pointed it a white wall. Check it out n get back.
Does anyone think there will be a fix for all these niggles?

I have had my note for a week. Try this: lower your brightness setting to a little less than halfway. Then open up a browser page that's all white. Now tilt the screen to the side in either direction, you will see the whites become green. Let me know your observation.

It does a little but that doesnt bother me too much. Its more the scrolling i was on about in some apps, mainly noticed it in the xda app. Doesnt matter which brightness setting i have it on, i still notice it in the xda app

Would anyone consider sending back their note and exchange to something else because of this problem and others?

Duno myn just went the more I used it
it's a software problem.
i've noticed the same thing happening to me, whites becoming green in hue while browsing. this issue is especially pronounced when browsing xda using the xda app, and so to determine if it was a hardware or a software issue, i screen capped instances of the screen being normal and being greenish.
result is the greenish hue was still present even in the screen capture. pics below are the actual screenshots and a comparison with raised saturation to better show the difference.

ok, i just tried it on mines, and yes its apparent. its like when you scroll, it becomes beige but as soon as you stop, the background becomes green. i would personally keep it because i think everyone has this. also, the next device might be worse. like on mines, at first i was annoyed about the white becoming greenish when tilting the device, but based on other folks reposes, it seems that everyone's does it, so i have decided to keep mines.

I got a big GREEN splodge when pointing to a white background. This is not a screen problem, it's a camera problem. You not notice only in the screen but also in the actual picture if you take it.
Found somewhere an explanation of this problem that is general to all kind of cameras that have the sensor to near the optics.
I think Samsumg has tried to solve the PINK problem by software, just trying to apply an opposite filter to the PINK, and that's why I getting GREEN

Ive got the exact same observation... But its not that bothersome. Im thinking its in the software as its obviously not a "capability" thing. I get great whites, etc.
Im just happy with no dead pixels and damn this device is nice!

I have noticed tyr exact same Thing. When i tilt the note (not by much) the screen gets a green color. Guess that should disapear.
Also when i scool there is a slight color change.

Blue images when using stock samsung browser.

As the title says, I am getting predominantly blue images on the stock browser. This started 2 days after purchase and it's only on the stock browser. I cleared the cache and all data and still same issue. Don't really want to factory restore seeing as I just got everything set how I wanted it to be. Any ideas?
Have you enabled Power Saving?
That turned my stock browser bluish on my GT-N7000

GS4 ACTIVE [Home button Wake]

Does anyone know how to disable the home button from waking the phone? Its very annoying when it wakes it in my pocket. Since the hardware buttons poke out so far its a lot more prone to happen and its killing my battery.

Display of black weird

Anybody an idea whether this is a display damage? Black appears not normal.
Sent from my SM-N9005 using xda app-developers app
Black crush
Well,this is called 'black crush' or 'black clipping'. It is still there a little bit,but nothing serious. The first Note was horrible... Don't worry,nothing is wrong with the phone,it is a software issue,and (I think) it will be fixed soon.
Im very confused as it really distorts the display of the black.
In the settings the search field has a deep Black. Rest is more or less grey.
In the toggle menu the bottom bar has weird stripes.
It's not just a small issue. ...

You posted screen shots. No one can tell anything from those you need to take a picture of the problem using a camera. The phone's been out for over a month now. If what's happening to you were wide spread I assure you it would have been brought up (numerous times) by now. If whatever you're seeing was like that out of the box (before you loaded any apps) it's probably a h/w problem with your specific device.
I have the same issue too on my Note 3!
I'm from Singapore here.
I didn't notice that the pictures appear perfectly normal on other displays.
I did some shots with a camera.

That isn't normal - I'd you are running a custom ROM I'd take back to stock to see if the issue persists, and send it back if it does.

Mine too. Isn't that supposed to be the way the display looks? Just kidding.
A display that looks like this isn't normal and if there were a lot of them people would be going nuts.
It's either something s/w related that's fried the graphics drivers or a h/w problem unique to specific phones. If it remains after a hard reset than it's h/w and the phone needs to be exchanged.
Tried the hardware reset but didn't change anything. Bad luck this time.....

That is really something wrong.
It suppose no strip at telco area.
Beside search bar, the rest bottom part is suppose black also not grey.
I believe your screen is defective.
I've factory-rested and it's the same.
Re-installing exactly the same J1 firmware (in Singapore it's the latest) via Odin also yeilds same result.
Another friend of mine is facing the same issue.
However, the ambience at the Samsung stores are so bright, and it's hard for the customer service officers to see
Well I'll see what Samsung After service Germany will say... the point is that the screen looks ok if you test the blue, green, red and black screen test under *#0*#. But during normal use I'm faced with the problems as shown above
I'll keep you updated.

Most likely a hardware problem. I'd take in to your carrier or wherever you got it from and see if they can help.
