Pink screen

Wow! The pink screen sure is annoying!
I just got my replacement phone from HTC (at&t N1) for my reception / audio issues.
The new screen looks horribly pink - noticeably so.

I think its just luck of the draw with these screens. My first phone had a slight green tint, but was pretty close to natural colors; the replacement is very red'ish tinted. My original phone had an issue with the cpu throttling not working properly any more. the replacement screen causes the grey areas to appear pink/purple'ish. (even the black areas)

This is really bad - I will probably ask for another replacement, especially since the new phone has really bad reconnection issues. QC on the nexus one is just beyond bad! This should NOT happen.

I wonder what percentage of people have this tint problem...

[POLL] do you have the red tinted screen?
If you do not know what I am talking abut, or never noticed it; turn your screen brightness down to its lowest setting and then open up the stock android keyboard. (it becomes most pronounced at brightness settings below 50%) If you have the problem, then the keys an surrounding dark grey will have a red tint to it. The red tint is only an issue for the various shades of grey; black and other colors are not affected. (on my screen anyway, and white may be a bit off as well)
The reason I ask, is that I recently had an issue with my CPU getting stuck at 100% load at random, so I sent in for a replacement. I got the new phone in the mail, and it appears to be a new, or at least a failed/repaired assembly line unit. (received a -04 part number btw)
This thing has a bad red tint to the screen, worse than my GFs nexus which we also received a replacement for. (both replacements had worse red screen) I might could get used to it, but currently it is distracting to no end.
Problem is, is that my original device has seemed to stop getting the random 100% CPU load problem. I wiped and flashed back to shipped ROM and then re-did the update path through to 2.2 build. (completely stock no root or unlocked bootloader) I did have an issue with the CPU getting stuck at 100% after that, until I uninstalled an app and reinstalled it; seems that when switching from this app to another app would cause it to get stuck. So now I am on the fence about wether to keep the new device or the old one; the CPU issue may actually be a hardware issue and come back at random sometime, or it may not.
edit: BTW is there a way to edit the poll? Iy seems that some have the tint issue at first and then it gets better. I would like to add that option.
edit 2: Pictures of the new and old devices. If you can also see my trackball is also sunk in too deep.
New on left, old on right.

No red tint on mine.

none on mine either

The first couple weeks with my nexus it had a purple tint at the lowest brightness. This is now gone.

So it got better? This could explain why the GFs screen has much less red tint than the new devices. Just sucks that my original phone is near perfect in the color area.
As far as it being purple tint, the darker colors tinted with red would appear purple-ish. The only colors I have noticed being "off" was grays and brown. (when displaying full screen single colors)

easiest test is to go to htc's website, ash/grey deigns of the site are in pinkish tint. Which is the case for me and as well as my friends, he is on Tmobile, I'm on At&T. I think this is a problem in the newer batchs of nexus. I bought mine this April.
In any case, it doesnt bother me, not a deal breaker considering I have Flash 10.1 on my phone

I would say majority of the recent owners from last 4-6months.

I bought my nexus at the tail end on January. (around the 25th) I bought the GFs nexus a few days later. (she has the tint issue)
And I added pics in one of my prior posts.

Really would like to edit this poll; add about the self fixing and about when you bought/received your device.
This poll will determine if I bother with having a third replacement sent out. I'm also running a solid red screen at full brightness for about an hour, see if that helps take out some of the red's over saturation. It affects yellows as well, I just noticed.

I ordered my Nexus when it was released and also had a purplish tint when brightness was down. I think androidandme did an article about it... maybe. Anyway it didn't bother me because I always leave it on full brightness anyway. Just checked it out on low brightness for the first time since I got it and I can confirm that the tint went away.

There is a stickied thread in the Desire forum about screens with a pink tint, might be worth reading if you have it. No idea what's in it though

I agree it is something to do with the type of display, but it seems that many do not have this issue; my first device did not. If I had always had the issue, I would not be noticing it now, but the difference is jarring.
I'm tempted to be careful with the "void" stickers and swapping the displays out myself.
Leaving the solid color running helped a small bit, but not enough to really matter.

I don't notice the tint as much unless I have the two phones side by side; though I still see it. As you can see by the pics I posted on the first page of this thread, the difference is huge.

Blueish screen?

I haven't received my Galaxy S yet but everytime I use my friend's I think the screen is just too blueish. Mostly the white parts. And I also think a "square field" is visible all over the screen. Is this because the resolution is too low compared to the size?
The phone itself is great so I still want it, but I'm afraid the screen will make me disapointed, especially since I've read so much about the Super AMOLED is so great.
Are all Galaxy S' screens like this?

What is the "square field"? please explain better.
And let's start from clearing the point of resolution/size-
800X480 is more than enough to go up to 7". If anything, it might be the pentile matrix that the screen uses.

I guess it's these "squares" I see: http://www.engadget.com/photos/iphone-4-vs-samsung-galaxy-s-display-face-off/#3115591
You're probably right that it's more the pentile matrix I notice more than lack of resolution.
I cant understand why many reviews says this screen is very good when it's very noticable.

I've seen mentions of different Galaxy S phones having different colour temperatures, though mine seems fairly cool.
PenTile does, unfortunately, make text less sharp, and there is a bit of a screen-door effect (I think that's the term you're looking for). It's a tradeoff for having a Super AMOLED screen - excellent contrast and very bright, but not as good as a TFT for text. I've become accustomed to it though, despite my misgivings (but a non-PenTile SAMOLED really would be the best screen without question).

What's the good side with PenTile? And yes, I've searched for "screen-door effect" and it seems as if that is what I'm seeing.

Yes, Galaxy S display seems to have quite high colour temperature. You can sort of calibrate it using the calibration app that was developed for Nexus One a while ago and is now part of CM6, but you have to run Froyo, install it manually and lose video overlay, so it's not really usable right now. Nevertheless I've managed to calibrate my SGS to more or less 6500K using it.

What is the downside of losing video overlay?

Not being able to play back videos and shoot pictures and videos Or, to be precise - you can do all of that, but all you see is white screen

Oh. Well, guess I'm not going with that solution then
But since it can be done through software, does it mean that Samsung could make an update and fix this?

I had this on my old galaxy S and coming from the x10's tft it was painfully obvious the white colour had a blue/green tint to it. I then got it replaced and the tint was still there but not so obvious. Now after a while the white colour looks perfect white. I think my eyes have adjusted or something.

Ok, guess I'll have to wait until I get my before I know how bad it is.

My friend got a blueish Galaxy S I9000. Mine isnt that much!! Next to his looks like mine is Redish, but mine next to my Monitor looks blueish! I believe some Screens have more blue tint than others

Mine is very white. Put the phone on a white screen (using a screen torch app) and the screen looks whiter than a piece of white paper.

Hey all, keep us updated if there's any application that can change the color temperature without affecting the functionality.

I got the phone a few days ago and my friend's is defenitly more blueish than mine. I dont notice the screen-door effect anymore so I'm very very happy with it.

I´ve read something on a German Mobile Phone Review Site (don´t know the which one it was now) and they said, that this is normal, because of the AMOLED Tecnology. They said that the Colors will loose the intensity over the years and as blue is the most energetic Color in the spectrum it looses faster the intensity. That is why it looks now maybe a little bit diferent. After a while it should normalise, because it was planned by the manufactures.
Ok found the Site. Heres the translation:
Higher blue components of the display of the Galaxy S may have been deliberately created by Samsung with the idea that the blue OLEDs are aging much faster than green or red. After months of use should mitigate this effect and color balance to be balanced.

They could do that if they wanted to, yes. But don't expect them to do so, I don't think colour temperature is of any importance to them if it stays within usable range.

Got this tip a while ago on some other thread - you can start Video player, play some video, go to Settings and change the Colour tone to Warm. It stays changed even when you leave the player. It's not perfect, but it helps a bit.

Actually, YES! Your eye do adjust to the white that you are looking at.
You've been doing this all of your life and haven't noticed it. The light in the morning is a very different color than the light at noon. In the morning, it is likely very red if the weather is good, and very white at noon... yet everything looks normal to you... because your eyes adapt to the color.
Adjusting to your screen is the same way. But compare it side by side with another screen and one or the other is going to look "wrong", usually the one you haven't been staring at all day!

Congratulations, your brain has created a special filter, using a process called "adaption", by the human vision scientists, that blocks the screen-door effect. You didn't know it, but your brain created one years ago that blocked out the 'striped-lawn' effect caused by the columns of RGB subpixels on conventional color displays. That 'striped-lawn' effect was just as visible the first time you saw one, but that was likely many years ago.

Okay so this blue tint thing is somewhat strange, still no clear answers.
Some people are saying "this is normal for super amoleds." I have to disagree. If this was normal, then every single Super Amoled would have this blue tint. I've put my samsung galaxy s vibrant side by side next to the samsung galaxy s epic, fascinate, captivate and other vibrants. Some have a blue tint, and others don't. Others have nice rich whites, while some like mine have a blue tint.
Makes no sense, so I'm not buying the "all super amoleds have this blue tint" statement. They don't all have them!
I've used my phone for over 2 months now, and the blue tint is not fading at all. Something else people said. I don't plan to keep this phone for 10 years, waiting for the blue to fade, I want nice white now, not blue whites.
Anyone have any updates on this blue tint some galaxy s phones show?

[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

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.

Ok going by the screenshots is moon+ reader
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.....

Ok going by the screenshots is moon+ reader
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.

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.
