[Q] URGENT HELP~~~Are These Dead Pixels???

Hi Guys,
After hearing so much problems with the Note screen, I had another good look of mine tonight and found these weird looking white lines/dots at the bottom left of my screen.
Are these dead pixels or stuff underneath the screen?
HELP Please.....might have to get an exchange with handtec...so much hassles....

Those look like stuck pixels to me.

You have taken a pic with the default scratch guard on just remove and slightly clean the screen and see if it goes away, but most probably its 2 dead pixels, mine 1st one had 1. Quality issues with samsung !

I'm pretty sure it's not between the screen and the default protector....where did you buy yours from?
Seriously...I'm very disappointed with Samsung now....I mean, I have heard many people having problems with their screens, but never thought I would get one of them defected ones....

Looks like dead/stuck pixels I'm afraid.

Can you get a macro shot? It's kind of hard to tell without a closer view. When I've had stuck/dead pixels in the past, they've always been very discrete, tiny dots without any haze or blur, which it looks like yours has. I also wonder if it's something to do with the screen protection film. When you do a macro shot will you lift it and clean the screen?

Here....I have lifted up the screen protector....I didn't take off the screen protector was because maybe if I didn't handtec might exchange me the phone quicker....but what the heck...I need to be sure anyways...so here are the pictures.
Man.....so much trouble for this phone....very disappointed with the build quality of the screen now....
Now I will have to wait for a while to get my exchanged new phone ....
Any ideas how long it might take? I read on handtec that if the item is returned after 10 days...it will go under warranty and so does that mean they won't exchange my phone straight away??? Anyone got any experience with them??

nuh...I have tried to count them...there are a least 4 dots plus a line....very strange....they are also bright green instead of being white.....can't see them with the black background....
Shows you how bad of quality the phone I got....
I am very surprised I have not noticed them before.

Just found out online...there is a difference between stuck and dead pixels, and apparently stuck pixels can possibly be fixed yourself...might give it a try....
nuh...none of the apps seem to work

Been using JScreenFix for the phone for about half a day....just flashing the screen.....
I think the pixels have gotten a bit darker......don't know if it's my eyes playing tricks on me or not....but will continue to flash the screen for the rest of the day and then check it again tonight....hopefully then will be gone
The thing I don't really get is why the green dots (more than 3 of them) would only appear on Green, White and Grey backgrounds, and not appear on the Red, Blue and Black Backgrounds.....Anyone got any ideas?

because every colour of the spectrum uses green except for red, blue and some combination of red blue
black is when the screen is off

Hi there. I just bought the Note few days ago and I can confirm that I have the EXACT problem as yours. Except mine is just a dot. It's like a pixel that seems to be the only brighter pixel when the screen displays full green, white or grey background (specifically used the LCD test *#0*# & Burn-In Tester Pro app).
I assume that it is a stuck or a hot pixel simply because.. it lights up. Unlike dead pixel is like.. a dead bulb/pixel (Assumptions. HEHE.)
Actually on the day that I bought the Galaxy Note, I was really careful. I even dialed the *#0*# LCD TEST at the shop to look out for screen defects. It was FLAWLESS. So I bought it. And I have this habit to look out for defects even after purchase, so I always go to the LCD Test and Burn-In Tester Pro app to check, and is still perfect.
Not until, last night, I dialed *#0*# and hit "Black (Vibrate)" with the intention to check for the "blemishes/blobs" in a totally dark room. It was only apparent after my eyes had adjusted to the darkness and I do see the not so obvious blobs. So after noticing that, it didn't bother me so I happily watched an Blu-Ray quality video (Despicable Me) and that's when I noticed the BRIGHT pixel which I assume it to be a STUCK/HOT pixel. I hope it is just a stuck pixel which hopefully can be fixed over time. Don't know about hot pixels..
Right now I'm playing a Full HD video of a downloaded YouTube video called Pixel Fix, on loop, with Video Brightness set to full. My instinct says to try it out but i do know that after awhile, since it's an AMOLED technology, colors could be darker over time as the pixels slowly 'burn-out'.
AND if it doesn't work, I might try to turn off the phone and leave it somewhere really cool/chilled. And switch it on after awhile when it reaches room temperature. I read it somewhere that it works to remove stuck pixels. They put their phones in a fridge in a wrapping and they said it worked. I forgot though where I read it from.
Oh, it's this one --> http://forum.xda-developers.com/showthread.php?p=21025093
Someone managed to fix a dead pixel. Hmm, but it's a phone with an LCD screen. Nyeh.
Good luck to us. Man, it was only few days ago when I bought the Note. *sniffs*

Seems quiet here. Seems like not many people have or aware of this bright spot defect.
But I found this which seems to concern about the matter. http://www.patentgenius.com/patent/7955151.html
I guess it gives some idea of what it really is. Cheers.
And I am gonna let this 'problem' go this time cos it's so small but I do hope that it won't get any worse. Or if it fixes itself that would be a miracle

[Q] Yellowish screen?

Hi there,
The Galaxy Note is my first phone with a LED screen, I had a Desire HD before.
Since I got my Galaxy Note, the screen seems a bit yellowish to me.
When you tilt it a little bit to the side, you see the while colors becomes more white, but when you tilt it back, so the screen is right in front of you, then the white colors looks a bit yellowish again.
Is this normal for a LED screen?
I don't like the yellowish tint at all, but for the rest the screen looks amazing.
Thanks for your answers

Hmm I don't really notice any sort of yellow tint on my screen but then again I'm not the most color observant person . What you can try is go int settings==>display==>screen mode and change it from standard to dynamic or movie. I have it on dynamic and love it.

Yea I already tried dynamic mode, it makes the yellowish tint a little less, but it's still there.
You can notice it by yourself by tilting the phone.
Just put something on your screen that has a white color, and watch the screen from the side, it looks much nicer then.

Ohyea, by the way.
You can also notice the yellowish very good if you put the screen mode on movie

Just got my Galaxy Note N7000 today and noticed the same issue on mine. Tilting the screen slightly makes the whites look pure white while in its normal position the screen looks kinda yellow. I am not being able to understand if this is a faulty set or not

SAMOLED screens are supposed to have superior viewing angles, it is believed that the Oleophobic coating is causing the green/blue/yellow tinting that you see when the phone is tilted ( well in your case its a direct view ) my first screen had absolutely no color shift even at the most extreme angles, the new one I have now has a blue tint unless directly viewed.
The norm is supposed to have great viewing angles and only shift in really extreme and non usable angles.

Well, you don't have to be upset like that.
What I'm trying to say is that if you tilt the phone, it has great colors.
But when you look straight onto the screen, you see a yellowish screen.
Your conclusion is that the viewing angle are very good, and only shift in really extreme and non usable angles.
Looking straight onto the screen should not be a non usable angle.
And Im not the only one who's saying it, but when you tilt the phone, the colors looks much nicer.

Im not upset, I just found it amusing why it was not understood right off the bat.
Have your screen/phone replaced, thats clearly a quality control issue.

Interesting.
Actually I'm not a whiner, so I can live with the tint for 2 years, but still...
If I will be in the center of my city, I will ask the phone store what they think, and what they will do to solve it.

True.
But I don't expect a device to be defect when it is just new.
Still there are also some people that say it is normal.
I also got a friend, he's a designer, and works with photoshop etc, and colors are very important to him.
I also told him about this issue, he said it happens more with screen, and it is seen as normal for these screens where it appears with.

This is the reason why quality control is so random with samsung, people accepting defects as normal but dont let my expectations be yours as long as your happy with the device thats what is important.

He does have a point normally a screen comes in warm,cool and neutral depending on the factory calibration. These things can be normal as long as the user accepts them to be.

No problem, Keep us posted on whatever you decide.

I've had four blue Galaxy Notes and one white and they all exhibit varying degrees of tint with some less noticeable than others. Some have a more warmish yellow tint while others are cooler with more of a blue tint. It was the same way on the Galaxy S2. The best you can hope for in getting a replacement is one that has a tint that's less noticeable or if you prefer a cooler tint to the warmer tint.

Visible pixels

Just noticed that I can visibly see the LED pixels on the screen.. Anyone else have this happen after having the phone for a bit?

It's 493ppi so seeing 1 OLED pixel seems out there even for most people. I have 20/10 vision correct with contacts and I can't see them even if I try. Maybe if I had a dead pixel I could see it, but normally I can't see anything.

I couldn't get the other phone to focus on the pixels. I put in a request with AT&T for a replacement under warranty.. Just concerned with the build quality of the device since I've only owned it for a couple weeks and have this issue. Its a damn expensive device to have issues like this.

I didn't have that issue on my first Nexus 6 but I did have a camera issue. My second one is excellent no issues so far. I had my first one for 7 weeks before I had to RMA it.

I have perfect vision (my optometrist is jealous) and I can't resolve individual pixels on the display when held at "normal" distances.
After using the Nexus 6 though, I can resolve the pixels on my N7 LTE under certain conditions, after never having noticed it before. Drives me nuts.

That's how it is when I use Mt wife's S5 it's almost annoying because I can see them sometimes when I didn't used to. That started after having my G3 for the past 7 months

So just to be clear, when y'all are looking at the screen with a white background, you don't see red, blue, and green dots, correct?

Not corrected. I can see them also. It is mostly because of the uneven pentile pixel layout. Coming from an LG G3 which is stripe RGB you will definitely see a difference in quality. G3 is much more ordered and cleaner vs N6 a bit grainy with slight pink side. However, in my opinion it is an illusion because of a vertical vs diagonal layout. In both cases the blend is even.
My guess is that your new unit will not be any different.

My previous device was the G2 and in certain lights you can see the pixels with the screen off, especially outdoors. However, I don't see the pixel arrangement with the screen off on the N6; and I don't recall seeing the pixels prior to today.. Maybe it wasn't evident at first and maybe my eyes are now focused on the pixels, but I don't think you should be able to see RGB light reflections when viewing the phone display straight on. My HP laptop has the same affect when the screen has some wet spots; but the fact is, I can wipe dry those spots and the RGB reflections are gone. I don't have time to go to a brick and motor store to view the phones on display, and the new device should be in my hands mid-week.
Here's a thought - I installed the Skinomi Techskin a few days ago (probably a week now). Wondering if this screen protector is causing this?

So are you talking about seeing pixels when the screen is on or when the screen is off?
The die of the pixel arrangement will be visible under certain angle in just the right light when the screen is off.
Also, screen protectors can cause this to be amplified for sure. It all depends on the quality of that screen protector.

This characteristic is just one of those things you have to put up with when you're dealing with resolution cheating samsung crappy pentile amoled displays. I was hoping that the QHD would be enough to overcome the pentile, but that doesn't seem to be entirely the case for some.
At least (if tmo ever decides to actually ship it) it won't be as bad as my last cheating samsung amoled... a 4" 800x480.
I figured going into this, that the display would be pretty crappy. Too big, and amoled pentile... but after suffering with non-nexus devices for a few years (last one was a "nexus zero" -- ADP1...), I just don't feel like fighting with the thing, so fact of being a nexus > crappy display.

Yellowish display?

Anyone else's display seem to have a yellowish tint? Mine seems very yellow looking at it straight on. But when I look at it angled either from the bottom or top it looks perfectly white with just a slight bluish tint. Either way it looks much better than yellow.
So what I'm trying to figure out is of I got a bad unit and if I should go get a new one. Only reason I am even considering not exchanging is the whole "scratchgate" bs.
Anyone care to weigh in?
BTW I have the 64gb black.

Comparing mine next to my LG g3 I noticed a yellow tint as well. Not a deal breaker for me as I rarely compare screen to screen but I've owned a gs2,gs3, and gs4 and there is always some yellowish tint discussion that pops up. You can keep exchanging until you get a more bluish tone but I don't have the energy any more lol. Screen still looks great to me!!

Blame AMOLED tech. Your options right now are a slightly yellow screen with generally more accurate color reproduction or a slightly blue screen with less accurate overall color reproduction but mildly more pleasant whites (to most people).

It wouldn't be a big deal but its really bad because its centered. By that I mean when I look at all the different sides from straight on I can tell they are more blueish and it makes the center look even more yellowed. I realize the amoleds generally run warmer in tone but it seems to me that the whole screen should at least carry the same tone from the same angle. Obviously because of the curved nature the color will shift on the actual edges of the screen but everything else ought to be the same color/tone.
Or am I totally off base here?

Doesn't really answer the question which is...
A: is it possible that my display is defective since it really only shows a warm yellow tone in the center most portion of the screen?
B: is this going to be true for all sgs6e's or is there a chance of having one where the tone is the same throughout the entire display face.
I understand color shifting and how is inevitable, but I would at least like my screen to have the same tone from top to bottom (obviously the edges will have a different tone done they are being seen at an angle when viewing the phone head on) rather than Top:Cold Middle:Warm Bottom:Cold
Sent from my Samsung GS6edge

Just turned on Adaptive Display which seems to make the whole screen more uniform in tone temperature however angles are still a bit of a..... well..... bi*** because they remind me of the pure white coloring I've grown to know so well. But I suppose this is far more livable than before which was almost unbearable (thanks OCD).
May still try to swap for a new unit in a week or so just to see if anything has changed.

I have s6 edge too (32gigs black) (Indian Variant) and I also have the same problem. Coming from note 4 so this yellowish tint really is deal breaker for me!

you sure it isnt the adaptive screen setting?
what I found is if you are using the adaptive screen mode and reading a webpage w/ lots of text, it sometimes will change the tint to warmer which ends up with a yellowish screen instead of white, which may cause you to think that the screen is yellow (thats what I thought the first time I saw it)
try to change the screen type to some other settings and see if that get you the white color?

I am having the same problem. I know it's a defective screen because I have two S6 Edges here.
My black sapphire 32 gb has a white screen
My new gold platinum 64 gb has a yellow screen and its very annoying. I'm probably gonna exchange it

Hello . Please do tell if you use a screen protector film or glass . Cause i have the exact same problem and everybody saye it's the protector but i dont think so . It happend after a bootloop and because the phone turned too hot before i download the stock rom i decided to put it in refrigerator. Battey ran out and when It realized it the phone was too cold maybe next to 0 degree . After the flash was done I noticed the color has changed . So I'm kinda unsure

Screen Issue???

Ok. Is anyone facing screen issue on your P20 Pro? There seems to be a gradient colour shift which is very obvious in a dark room when the brightness is set to low. Plus it has a green hue to it. Have a look at the picture attached. Thank you.

I tried it for myself and with brightness turned down to zero on phone and in the app i can also see a very slight hue.
But to be honest, i am much more comfortable reading with some background light so i can at least distinguish something of my environment , and then this is a non issue.
For completeness i took a screenshot with my camera , and it's way worse then what i could see with the naked eye.
With the naked eye it is noticable , but not so bad as the camera makes to believe.
Anyway , a non issue for me.
And since my and your screenshot are suffering from the same hue shift , it might even be a problem with the moon+ reader.....

But to be honest, i am much more comfortable reading with some background light so i can at least distinguish something of my environment , and then this is a non issue.
For completeness i took a screenshot with my camera , and it's way worse then what i could see with the naked eye.
With the naked eye it is noticable , but not so bad as the camera makes to believe.
Anyway , a non issue for me.

Thank you very much for following up. It happens in the gallery too. I've tried it with different pictures that have solid colours such blue, red, green, grey, etc. Do you think the warranty covers intentionally? I bought the phone with full of excitement while I was in Singapore for a holiday. I love this phone so much but the screen is bothering me. Sigh!

I'm pretty sure its not covered , the screen works flawless under normal conditions even in the the dark. Only when i go to extreme's like setting negative brightness levels in software the problem really shows up.
I will never have this problem unless i actively go and look for it.

same for me. the vertical and horizontal lines are not really an issue for me, i though i can live with it: i had the same on my p9 plus but on the left, there is a 2cm zone on all the height really darker and it made it almost unreadable at night (lowest light), even with screen filter or not.
i returned my phone and now i must wait to order a new one... my provider tell me they will not have twilight anymore.
i'm very disapointed.

Amoled screens are always a lottery when it comes to uniformity. Sometimes you have luck other times not. There are good screens out there and this time around I got one of the better ones. I have seen others complain about screen issues so not all screens are good like with most phones that have Amoled. Below is mine at 0% brightness and the app you used.

Mine has the issue as well. I ll be getting my device replaced soon as it also has a slight gap between frame and back panel at top left edge

Same issue here. First P20 Pro had it from bottom to top (pinky purple at the bottom, yellowy green at the top), second one has it left to right, but more pronounced on the bottom of the screen.
Is it worth replacing it again? I'm not happy with paying a significant amount per month for this if the screen is bad on all of them.

I would like to check mine. What is the best way to check this?
Update: So i opened lcd test app on my p20 pro and here's how mine looked like in the dark.
I don't know if i did it right but tell me if i need todo anything more to check this propertly.

Oh ffs, my third one has it too. Significantly green in the top left running about half way down the phone.
I've now been to the store 3 times, it's a 96 mile round trip! Nearly 300 miles of fuel wasted on this rubbish.
I get "it's a chinese phone," but we're paying Samsung prices for it, these screen issues are just unacceptable!

Have p20 pro for 2 weeks now. Always thought it's some dark theme design before found this topic. Have top much brighter than bottom in low light conditions. Can't see in bright room or in dark room with brightness more than 50%. I wouldn't be worried if it wasn't so annoying while I watching YouTube before go to sleep. Half of the screen grey, another near to black.

99% oled screens has this issue. Some are less visible, some more. But every oled screen phone I held had this issue.
Now I have Note 9 and dark grays are uneven too.

I have a Note 9 now too and while it's not perfect it's one of the most even oled screens I've had when it comes to uniformity.
