[Q] pinkish/purplish hue at the top of the display? - Galaxy S 4 Q&A, Help & Troubleshooting

I see a distinct pinkish/purplish hue at the top of the display. This is very visible on webpages with white background and black text (or in e-reader apps which black text on white background). The white balance at the bottom of the screen is very different than the white balance at the top of the screen.
I tried putting display in various different mode but the hue stays there consistently.
Does anyone else see this? If not, I may just have a defective piece and need to take it back.
Thanks,
Osho

I did see that - but thought that was only for the issue that when one scrolls up and down - there is a tint/hue. In my case, even on plain white background, I can see purplish/pinkish white at the top and the "real white" at the bottom.

IMO faulty device and not related to smear or red tint issues

Oshogg, that sounds like faulty hardware. I have the same thing, except my tint is at the bottom of the screen.
I'm returning it to my provide for a replacement next Tuesday, when they get new stock in.
One thing to check, is the metal rim in relation to the glass... Someone I know who has the same problem as me noticed a slight "lip" raised at the bottom of the phone (I have this as well). Do you have this at the top? He suggested that it might be that the glass was pushed in too far at the bottom / top during manufacturing.

Thanks everyone for the responses. I went to the AT&T store back today and to their credit, they did an exchange right away without any hassle. I compared the new and the old phone displays side-by-side : it was a day and night difference. So, there definitely seems to be very low quality control (at least on the displays) at Samsung manufacturing.

can anyone else see horizontal lines on their screens?

I can easily see horizontal lines on the gray part of the notification bar as well as other gray things. my screen is an 0003 novatec. I don't recall seeing this on my 0002 novatec.

I can see like, individual cells(not pixels), if I look closely on anything, you are not suppose to keep your face close to and LCD screen, they have a minimal viewing distance.
it's pretty easy to see even from far away.
I need some more opinions before I decide whether or not to exchange it again.
I don't see horizontal lines but I do see vertical ones, the yellow bars on white/light colored screens others have mentioned.

same, except rev 002
no horizontal but i do see vertical even stripes.
if i use a flashlight or have the screen white, and i look hard enough, relaxing my eyes, holding it at a certain angle, i can see perfect vertical lines of separation. The lines are a very faint beige.
its like those 3d posters from the 90's.. If you concentrate and relax your eyes, you'll seen em. theyre perfect 5mm of separation it looks like.
doesnt bother me because my screen is rarely full white, and when it is, it doesnt cross my mind
002, nova
bah. I want to exchange it, but I'm afraid they'll start to not like me for exchanging so much while they could be selling them.
I'm not trying to be Capt Obvious but have you put a screen guard on? I had one on before that showed lines on the screen that were annoying....

You're afraid they'll start to not like you.... hmmmm... well, if you really want them to like you, then I guess you shouldn't make them do their job, which includes exchanging defective equipment... rather, just plop down some $$ and pay full price for a new one when available.
Are you holding the phone like 2 inches away from your face or from how a normal person would be looking at the screen?
I'm holding it two inches away from my face, but I don't recall seeing this on my first novatec. no screen protector either, unless this is part of the damagecontrol rom, which I doubt.

lolwut?
also, I can see it on the battery icon even holding it 4 inches away. what do you guys think? should I go exchange it? also, I bought my phone on June 5th. If I go into the store on July 5th to exchange it, does that count as within 30 days? (I counted on the calendar, July 5th is the 30th day after my purchase)
well I can't exchange it anymore, and I didn't, =P. also, I went to the apple store and checked out the iphone 4's and noticed they all have this faint gray line issue as well. maybe my eyes just have good focus. although, I have no idea why I didn't notice it before.
Lol, if you mean the lines in all the theme headers, that is the graphics they use. It's in stock, I can see the gradient lines on notification bar etc. I was looking at them up close in graphics editor while making a theme
I can also easily see the vertical off-white lines on my screen. They're very perfect & evenly spaced, I just find it strange.
I haven't heard anyone report them on Epson screens, but my 003 Nova they're pretty clear. Gotta swap my phone soon anyway (light leak, bad 4g, and bad battery cover) so I kinda hope I get an epson screen since the purpley blacks also bother me.

I can see it everywhere though, and it's very clear that it's part of the screen because when I scroll, the lines don't move. I can see on all websites, as long as it is not black. I can also see it on the battery icon and the bars showing signal strength.
2 days ago there was a horizontal line in the center of my screen and it had all types of colors. I rebooted my phone and it went away but hopefully that doesn't come back.

Newer Nexus 4's ALL have yellow screens?

The first Nexus 4 I received was a rev10 I got that shipped the third week after release. It has a perfect calibration with beautiful popping whites and dark blacks. Unfortunately, I had the issue where a portion of the screen would tint yellow (about the size of my thumbprint) after it heated up.
This annoyed me so I got an RMA phone and it turned out that the entire scree was an ugly yellow even without heat. This was shipped to me from jan 1-7 I forget the actual date but it was recent. It also had a sluggish vibration issue that annoyed me. I sent it back and they sent me another RMA phone that arrived on the 14th and what do you know, it also has a yellow tint to the screen. The colors are much darker compared to my original screen as well and I tried color calibration apps but they just don't look as good as the original. This phone is a rev11 if that matters.
Do all the newly made phones have color issues? Or are there well calibrated ones out there and I should keep on RMAing?
The new screens just don't look as good and are really ugly. Someone let me know if they have a good screen
If you figured that out from an extensive poll of people then I'd understand that conclusion but from 2 RMA that's just plain stupid!
My screen is white as can be, compared to One X its looks insanely good, the One X colors pop and are really vibrant though

My screen is perfect. You should maybe change the light bulbs in your place..
I have a revision 11 and a revision 10 which is going back due to speaker crackle. The screen on my revision 11 looks cooler but I certainly wouldn't have described either as being yellow.

It goes away after a couple days...
As ctowne said, it goes away after a while. It's the glue that is used to laminate the glass and display.
Mine was pretty yellow at the start, however a couple of weeks on, and it's absolutely fine now.
Yes let us assume that the two phones we received is indicative of all phones. Makes sense.

Yeah mine went away within 3 days at the very most. Also, you can adjust the screen settings with fauxclock if you really want to tweak it. As long as you have uniform yellow on the whole screen then don't worry about it. If certain spots are yellow after a few days then you might have a problem.
To those of you whose yellow tint went away, was the yellow tint uniform over the entire screen before it went away?
I just got my rev11 RMA, and I've only got a yellow tint on the bottom half of the screen. Should I expect it to go away over the next few days?
Also, just holding it side by side with my rev10, I have to say, in addition to the yellow tint, the rev11 just seems a little bit less clear and a little bit less sharp. Could be because it has the factory Google screen protector on it, I guess, whereas my rev10 has an SGP crystal clear on it.
On the plus side, the light bleed is improved on rev11. Nowhere near perfect, but signifciantly better than my rev10.
If the yellow tint goes away, I can live with the rev11. If it does not go away, it will be another RMA.
I got a Rev11 one, but never had a yellow screen from the start. I guess i've been a lucky one..
When I did my RMA, my rev_11 had a more yellow tint to it on whites.. I could really tell on apps like SMS...
colors look OK and I've gotten used to it..
My rev 11 doesn't have a yellow tint.

All 3 of my phones have had an uneven yellow tint. I RMA'd a rev10 first which had a brighter and cooler screen than the two replacements, but and uneven tint along the bottom 1/3rd. My rev11's, the one I sent back and the one I have now have a less bright display, and the one that went back had half of the screen horizontally yellow tinted, this one has yellow tint in the bottom left corner. It's the least tinted out of all of them.
FTR the uneven tint did NOT go away on my first two phones. While overall yellowness may clear up, the uneven factor doesn't change.
All 3 have had backlight bleed, was probably the least on my rev10, the first rev11 had it pretty bad along the taskbar and left/right hand sides. The second rev11 has it on the taskbar, but a little less, and the top left hand side.
The displays are just pretty crappy LG IPS panels, I'm certain most people will be on an RMA goose chase to get a phone without any uneven tinting/backlight bleeding. They'll exist, but how long do you want to ride your luck changing? I also think LG have changed the display between rev10 and rev11, as as I said both my rev11s are duller.
I got my third replacement N4 today (REV 11) and it (like the previous 2) has the yellow tint to the bottom of the screen and left edge in particular. Looks noticeably brighter the bottom half too (slight though). I'm really disappointed with this as I don't think it's looking like there will be any (or many) from this current batch that don't have this problem.
Does anyone know from a technical point of view why LCD panels are prone to this - why is it such a consistent problem in manufacturing? What exactly is the cause and why isn't it prevented? Any links? I've Googled it but no results...

Is the pink tint firmware or hardware?

I've got a stupid pink tint at the very bottom of the screen and I've had 2 exchanges of the HTC One before exchanging for the GS4 and the network find it hard to believe I've had 3 faulty devices in a row and wont exchange it. Anyways I canceled my direct debit and told my bank not to allow anything from them until they sort it but It's just bloody annoying.
The Three Ones I went through all looked like this http://s16.postimg.org/rz4843lud/image.png and now my GS4 has a pink tint at the bottom, lol, I swear phones are getting worse.
Can't say whether it is h/w or s/w - I know mine doesn't seem to have it ... or it's not obvious enough if it has
But I would recommend not cancelling the DD as it will probably have consequences on your credit rating. Phone companies don't care about you cancelling it as they will get their £££
Does yours have ghosting? When I scroll up and down in menus I notice like the blue bars on the edges of them it changes to a darker colour, you can see it struggling to keep up, even see the old text through the blue bars.

It's commonly known as screen smearing, and we have a workaround for that

My GNex had the pink, and my S4 whilst not pink had a noticeable difference between the top and bottom of the screen. Darker at the top than the bottom.
Had it exchanged yesterday... new device is perfect, just waiting for Samsung to sort the laggy TouchWiz out.
Yeh they wont exchange mine saying I've had too many....... stop sending me faulty phones then.
Anyways wont pay them anything until they sort it.
Just noticed the purplish smearing on dark menus,
Also pinkish blue when popping in and out of the keyboard

Thanks for the response sir. Yes, I've checked your fix methods, tried the first two, but none of them worked. I think I don't have any smearing issue, rather I've a pink tint at the bottom of my screen. So, the upper 3/4 part of the screen is bright, and lower 1/4 part is dark (pink/purple tint). It seems, its a hardware issue, tho i'm running dead pixels app (from play store), which says, it will take 30mins. It is still running, but I guess replacing phone seems to be the only option.

Defective screen?

For some reason now when I ran the screen test on the grey background I see two vertical lines. A light dark one on my left side and a light whitish one on the right side. I never had this before when I got the device. I did lots of searching and research and some people said it disappears by itself ... Can someone confirm this to be true cause I don't really want to RMA. I also notice that the lines get lighter as the phone cools down too.

My Nexus 4 here problem, left side on screen show black/white thin line 3-4cm.
Update*
Okay so the darker line went away after my device was cooler and idle for a couple of hours but it comes back once the phone is heated slightly. Does anyone know if its the glue adhesive or just a defect?

Misaligned screen

So I have the edge since the 11th now. And every time I have the feeling that the screen is centered to the right side, I notice it extra with a case. As the area between the bezel and the screen is larger on the left side.
This afternoon I looked with an magnifying glass and indeed saw that this was indeed the situation. It is about 0.1 mm or so but oh so annoying. Luckily I can exchange it, however there will be only phones I stock around the 30th. Keeping mine thill then.
Are there others with the same issue?
The attached version is not my phone, but just an example to explain.
To better understand what i mean I attached a picture. I have the black version but you could see it as the black line on the right side of the phone is thinner than on de left, so the screen is essentially to far to the right..
not the best picture for judging...
But I know what you are talking, I have seen a few devices now and all of them were different in terms of screen quality and alignment!
for me, the worst problem is the uneven contrast (darker sides) on most of the screens. i own 3 devices now and all of them have display flaws. two suffer from a yellow tint when tilting, the other screen has a slightly darker left side... :|

I know. When my S6 comes back from warranty repairs I will try to make a picture. The S5 I have laying around can't focus clearly enough.
Well I hope I won't have a replacement with tint issues or such. Because my screen is, aside of the alignment, pretty perfect. Maybe I'm a bit nitpicky but I think that's justified with these kind of price tags.
I still have till the 30th to get used to it or exchange it. An order for a replacement has been made.
People complain about issues of screen color when tilting the device.. When are u ever tilting the device? U should be looking at it dead on anyways.
Honestly I don't see anything from ur picture, maybe ur just crazy.. If it is a little little misaligned who cares.. It's the curve part anyways..

The picture I used is just to explain what i mean with the black lines on my phone. Imagine that picture with no black line on the right of the phone, so the screen blends in with the white. And a bigger black line on the left.
That's what i have, but my phone is black so i cant put it on a picture to explain it.
I can really only tell in a dark room, but there is ever-so-slight light leakage where the glass meets the metal on the bottom of my S7 Edge. I see the slight leakage on the bottom-left and bottom-right. Doesn't bother me much, maybe a little, but my experience with smartphones is you'll be lucky to find one with absolutely flawless everything including screen alignment. It's often not worth exchanging for a new one, which may have other issues. Plus there's the whole issue of setting the phone up from scratch again. My device seems to be working fine (this is my 5th day with it) so far, so I won't be exchanging it.
After reading this thread I checked mine and its is misaligned like you described. I then went to Samsung and they checked and said that its normal. Now that I see it, its driving me crazy.

Same **** with me. My screen is also misaligned and its driving me nuts with this phone price i dont know what to do about it. I have s7 edge btw same **** all over with the s6edge. I really didnt notice it when using the phone. I noticed it when im checking out the phone looking how pretty it is then when i turned on the screen i noticed that the left side of my screen has a thinner black bezel and when i look on the right it has a little bitty gap.
