Bluish hue around edges of screen - Kindle Fire HDX 7" & 8.9" Q&A, Help & Troubleshoot

Anyone else have a bluish hue around the edges of their 7" kindle HDX screen? It's more visible on white or light colors. It's like maybe 2 to 3 mms and then it fades to the correct color. I think I remember my HTC flyer tab having something similar but I only had that for a day before I returned it. It's real visible when reading a all white document. Just want to make sure it's normal or I have a bad screen or something before exchange period is over.

It's normal, is the way Quantum Dot display technology works. Basically it uses blue LEDs to produce superior colour reproduction.
There's a whole thread about it on here http://forum.xda-developers.com/showthread.php?t=2493235&highlight=blue

Visible "Pixel Grid"

If I hold my Prime under a bright light, I can see evenly spaced out lines of dots. They're evenly spaced out in both the horizontal and vertical directions. I see them on dark/black backgrounds, and I even see them when the screen is off. As I said, it's only visible under a bright light and on black backgrounds. Does anyone know what this is, and do others see it as well? Another way to describe it is that it likes like there are tiny glitter speckles evenly spaced apart from each other.

This is the actual touch-"part" of the screen. Nothing to worry about.

its the capacitive touch grid
duno if this is what u can see but it maybe the grid inside the touch screen. i have seen something that sounds similar before on my nexus one and concluded that this is what it must be.
Aaaah. Thanks guys! I've been inspecting it carefully since so many people have random complaints, and this is something I've never noticed on another device before. I think you're right that it's the touch screen. Thanks! So far, loving the Prime.

I had this on my HD2, but not on my Sensation. Not sure why some devices show it and some don't.

Found three bright lights on screen today!

I haven't realized this before until I bring up a new document from polaris app. I then noticed three bright pixels on my screen far brighter than rest of the screen.
I called Asus and they said if they can't fix the issue then I can choose to receive a refurbish or new prime.
Guys check your screen.

Are you telling me to check something that I have to look at every time I use it? Really?
I had this on my second one. But mine was more of a bright spot rather than a pixel. It varied in intensity whether my prime was plugged in or not. If it was plugged in it was way brighter.

Sh*t happens. RMA it. Least they are offering you a new prime! Thats good.
I'm pretty sure what your seeing are dead pixels. I have 2 currently on mine. For me it doesn't reveal itself under dark colors. But light colors seems to bring it out. When I rebooted and when the ASUS screen popped up I examined the screen real hard and noticed that those same pixels were actually dead. Which explains why I couldn't see it under black background. The Asus loading screen is black but it has backlight lit up to were I can see those dead spots. I don't know just my own findings. Could be completely different.
Edit: Mine was also a bright spot. Made more defined when under lighter backgrounds. Like I said. When under the boot screen look at it again maybe have to adjust it in an angle and you will see that it appears to be a dead pixel where that same bright light is.

I have one of these also. It's only visible on white backgrounds and even then it's not a big deal. It's bottom left when my Prime is in the correct landscape orientation.

anyone else have this

When im sitting in a darkish room with no
lights on in the room if i pull down the status bar or looking at dark pictures i can notice 2 black lines? Anyone else have this?you have to look kinda close and move the phone round abit tho to see it
Anyone?
What you mean black lines down the sides? Cos I see nothing else and they normal.
I see about 3 small spots which are darker than others but they are only small, i do however know people who own s3's which suffer from a problem similar to the one you describe, but they both decided it want worth a return (yes two of my friends with the same problem what are the chances?)
I guess you mean the irregularities in the screen on black background in low-lit conditions.
Depending on how prominent they are, it's considered normal for AMOLOED screens and similar effects can be seen on all AMOLED-devices.
My best guess is that some LED ranges get a tad too little power on minimum brightness when displaying very dark content so that they really stay dark while the others give a very faint flow.
(Such flaws and differences in the screen are one of the reasons why AMOLED can't go really dark like LCD's can)
I was just about to post this aswell. When I'm using the phone and there's a black background, I see a couple of extra dark dashes on the screen
Is there a fault with the screen?

[Q] Can the tint be fixed?

Hi, I recently bought an Galaxy S3. And i noticed that in the lower quarter of the screen looks a bit "whitier" than the rest of the screen. The rest of the screen doesn't have any colour in particular is just that the white looks more warmer. Before anything i should clarify that is visible looking directly to the screen. The real issue is with a grey background, like the market or the antutu background. That part of the screen looks more blue-ish or darker than the rest.
Well i talked with the salesman who sold me my device. He talked with him supplier and don't consider that the lower tint it's enough for a exchange.
Now, what intrigues me. Is that is only visible on a gray background( market, or antutu for example) But i test the display with *#0*# with the three different colour (blue, green or red) i don't notice any difference on the screen. The same with a white background there is no visible tint.
I really don't know what else to do. Could somebody explain to me why is only visible on grey background and not visible on a pure white screen?
Another question i ask my self. If the the tint is blue-ish. Is due to an over saturation of the blue pixels? If so, can this be "fixable" wearing the blue pixels on that part of the screen?
Thanks.
Try the app "Screen Adjuster" Increasing red and green will make it look less blue. Try it in increments of 5. There will eventually be a color temperature adjuster hack like there is for the Galaxy Nexus.
That helped to hide the effect a little. But the question remains. Which is the cause of the variation of colour temperature on different parts of the screen?

Defective screen. They should replace the phone. Or send it to Samsung for service.
Thats a bad screen I had the exact same problem. There are a cupple of threads here at xda and also on Swedish site swedroid. Some people get an accepted doa . I did not. However in the shipping from the service point to my retailer they broke my phone so I got a refund (lucky me). And my new phone is much, much better!

I think the exact same thing. But the salesman who sold me the phone don't think is a deffective screen because he couldn't saw anything when i showed to him.
The problem is that i couldnt show him concret evidence of this issue with the screen.
There is way to contact with samsung directly?
What about this:
If the the tint is blue-ish. Is due to an over saturation of the blue pixels? If so, can this be "fixable" wearing the blue pixels on that part of the screen?

How is the screen uniformity so far?

How is the screen uniformity on your Note 8 (outside of Adaptive display) I avoided the S8/S8Plus due to the red tints that affected portions of the screen, Ive seen a total of 20 display units for the Note 8 and only 7 had good screens the rest had 'dirty' screens when the display mode was changed to Basic/Amoled Photo, its a combination if either partial red tints or yellowish tints on sections of the screens and the demo units were just installed.
I check the screen with Basic mode, brightness under 50%, fire up chrome and check in landscape, also i use the stock sms app in landscape and i check if its grey background is 100% even from left to right.
I am just curious if Samsung has upped the quality control or its still all about panel lottery ?
EDIT:
Im more interested on feedback that is using Amoled Photo or Basic, as Adaptive mode drowns the screen with a more blue.

My eyes are very sensitive to the red or yellow tints. In Samsung's case red.
My wife's and I note 8 doesn't seem too bad, some red tints around edges depending on veiwing angle but very acceptable.
Mines running basic model also

Adaptive mode here. Absolutely flawless, thankfully. My S8+ had tinted edges but that was fixed by the update they pushed out after adjusting the edges color. My Note8 is hands down the best screen I've ever seen.

When say edges is it on the curved edge or even on the flat part at the top ? as I've noticed most of the red tint is from the top part.
Im also very sensitive to this, other things I have accepted like the grey full screen uniformity on AMOLED is just terrible compared to LCD.
I was hoping that this issue would be fixed. I had an S3 with bad color uniformity issues. My Note 4 is darker along the left edge.
Can't stand the tinting issues that these seem to have. Also dislike brightness uniformity. A lot. I understand that each panel is different from the next, but what is it that causes these issues?
this is why
It's better than my previous note, which was a 4 but still the white isn't as white as some lcd panels out there. I didn't notice any uneven red tint on the N8 either for mine or the wife's. Tilting and viewing and looking out for it I see it a little around the curves of the screen, nothing that concerns me. But there is some red tint in there but not as bad as some note 4 or 3.
Good thing is , there is an adjustment that can be made in the display setting to reduce the red hue should you feel the need. I'm liking it as it is in Reading mode.
My ZTE Zmax whites look better.

So to summarize, it's relatively uniform but I can still see a pink red crush/hue is present when white is being displayed. Using AMOLED adaptive reduces the red pink hue but looks like trash elsewhere.
So,yes it's still pink. Not much has changed since my Note 3 or 4 days. Then again those were pink or red in parts of the screen. Least the N8 is uniform pink.

I would also like to know the technical reason on whats causing it other than "manufacturing variance" and up until now samsung has not addressed such issues and some customers even struggle to have the devices exchanged.

Same here, but with my Note 4 one lower area was pink. T Mobile exchanged it and it was fine after the first replacement. The N8 is uniformly pink. LOL

Im from an iphone now and ill surely miss the uniform whites and the correct 6500k whites as the note 8’s ive seen all have way warmer whites on photo/basic mode

No, I dont have the resolve to go through that exchanging bull**** anymore, too old for that. Ill either live with it, or send it back .
Last iphone I had owned was the the 3gs and 4s, yellow tint bull**** on those also.
I've had so many iDevices and Macs and never have I seen a screen that I'd even consider good, especially in the area of uniformity. Always darker on one side or the other. Always a bit more yellow here, than there. I've exchanged so many iDevices over the years because of screen issues. Every iPhone release is loaded with crap screens. At least according to all of the threads on various internet forums and groups. That is one of the reasons why I've never tried an iPhone.
FedEx lost my Note 8 and I might just say screw it and stick with the Note 4. My wife's Note 8 has the best screen that I've ever seen on any device with a screen. The brightness is completely uniform. I'd say that it does favor red a bit, but I'd hardly call it pink. Very nice screen.

Indeed, mines not pink like some of the S8 images posted. but there is some hue all over it especially as I normally run "basic" screen mode. Turned the red bar down a little and or use adaptive and makes it ice blue, I can live with it.
Another observation I noticed, if the screen is in Basic mode and I turn on Blue light filter setting, but turn down the bar for the filter to min, the slight pink hue on Basic mode goes away.
Can you adjust the colors independently in all modes or just adaptive display?
Just curious, isn't "warm" supposed be somewhat yellow color in tone ? It seems like when you make the screen warmer it goes pinker.

Seems just in adaptive mode.

I have a professionally calibrated workstation display at my office. Whites look like paper and I adjust everything to mimic it.
I was able to get really close by adjusting in adaptive mode.
Problem is with our devices we take them everywhere and the environment changes dramatically, bright, dark, pitch dark, etc.
This plays tricks on our eyes big time! So what may look perfectly fine in one scenario may take on a very blue or very reddish hue in another.
You will drive yourself absolutely crazy trying to adjust all the time!
Like an EQ on a stereo, you adjust contour for flat response and leave it alone! (but most people constantly tweak it!)
Find a reference point and you will be good.
My panel is very consistent.
You want to see a bad display look at the Surface Pro! They may have decent color when calibrated but when the lights go out HOLY BACKLIGHT BLEED!
I am so done with LCD and just want AMOLED on everything NOW!

While what you're saying is generally accurate, that's not what people who have the red tint or purple tint are complaining about. I've seen many amoled screens from Samsung flagships that I consider defective due to extreme hues that can't be "adjusted" to normal. In addition, only adaptive mode can be adjusted, so when the screen is bad, you cannot use any other screen mode without the tint ruining the quality of the display.
