Display has yellowish tint to it. Help!!

So my excitement kinda came to an early end last night. I got my second replacement mt4g due to a bad screen. This one is perfect...except that when I was reading some text on a page with a white background, I noticed that from bottom to top, the white gradually goes from white to this yellowish tint. I will post a picture of it later on tonight.
My question is, do you have/had this problem and did you end up returning it or did it go away kind of like when this was happening to the iphone 4? I really hope this really doesn't become a full-blown issue like with the washed colors, because then I would have to request a 3rd replacement and make sure that it doesn't have dead pixels, dust under the screen, washed out colors, yellow tint, crooked ffc, creaky buttons, and gaps around the bezel. Thanks.
Here is an example of what i'm talking about except my display is white at the bottom and gradually goes to the color of the phone that is on the right, at the top.

Do you think that the problem is improper screen calibration and all I have to do is wait for a software update?

225 views and one reply?? Really guys?? Not trying to sound like I'm whining, but this is a serious problem and I think i'm not the only one. I just received my replacement, and it too has this yellowish tint towards the top of the screen. This will be my 4th time that I will be requesting a replacement, so in total so far, 4 defective phones.

ur phone has a bad screen. when black looks more light greyish and when white doesn't quite look white, bad screen.
return it, these are things u wanna check within the first few days!

I'm sorry, but it's really difficult to tell based on the picture you linked. Is there any way you can take a comparison photo with a good screen?

I can't see anything wrong from that photo. It will take something more than this to let others know if you have a problem.

The blacks never looked grayish, the colors were bright, crisp and vibrant, it was when looking at something with a white background. This issue has nothing to do with the washed screens that people are getting.

I figured it out based on a chat I had with a friend. I think that the backlight was improperly calibrated or something. Sorry that I can't take a better picture as I have already received my exchange which is much much better, the light is just more distributed evenly then the previous phone. Plus it doesn't creak, the ffc is dead centered, and light doesn't leak through between the bezel and the screen at the top of the phone. After 4 exchanges(5 phones total), I finally got a "perfect" device.
Here is a side-by-side shot sort of(I returned the defective device before I could think of take a pic of them together due to my excitement!)
You can easily tell that the screen of the phone on the right has way more light at the bottom of it and the top doesn't which results in a more obvious yellowish tint. The phone on the left (good one) doesn't have it as bad, the light is distributed evenly. Both were on auto brightness. The good display's(right) brightness is down a bit more but it doesn't matter since I tried to increase and decrease the brightness on the defective one(left) and it made no difference.

Please help me choose a screen (pics inside)

My friend bought two galaxy s ii , one is for me and the other is to sell, so obviously i want the best one for me, i have heard the galaxy s ii has yellow tint/spots issues and i just confirmed it's true with my own eyes, but i still want a second opinion, without telling you my favorite option which screen would you choose? notice both are running different firmwares , but both are 2.3.4 , it may have something to do with the screen calibration of the firmware itself i really dont know, both phones are at 100 % brightness, sorry about the quality but that was the best my aging cybershot could do also if you any advice on some test pictures to make a better comparison they're welcome p.s. the circle shown on the left side is the reflection of my camera

Your best bet would be to run a screen testing app (Or the in built one) and test for dead pixels. Short of that there shouldn't be any noticeable differences.

Well right looks better but you should probably run a screen test.

No offence but both aren't that good.
Looking at the bottom image, you see that the right one has a more yellow tint to it than the left one but the left one has a 'circle' on bottom right.
But i'd keep the right one.

I would probably get the one on the right

want information about nandroid backup
can someone guide as i have taken a nandroid back up and it has created a backup file at sd card as "backup", but when something goes wrong when we try to install custom rom then if we restore backup in cwm will that restore whole contents of my existing rom or how.....please revert.....thanks in advance

I will choose the left one. The right one has yellow tint and it is darker than the left one.

I'd choose left and drop brightness in everyday use. the left has nicer whites whereas the right one is nicer colours.. It's more difficult to find a AMOLED screen with good whites so that's my reasoning for choosing left.

In that case I go for the left one.

plus: check the mic volume too

Where were they made? (You can check under the battery)

Che k the screen setting if you have chosen movie-dynamic or typical.

Why did your friend buy two phones, with the intention of just selling one?

Ok i used "screen test" and the one on the right has nicer colors, but its ridiculously yellow when displaying gray and in the dimmest option, the browser in the dimmest light it's ridiculous, really, i'm gonna edit later and more pics, in case you're curious

Yellow screen ?

Hi, i have one question for n4 owners.
When you look at your phone like this :
Is the screen look a little bit yellow ?
I hope is not a problem, juste ips technology :fingers-crossed:

410 err on the photo but it's probably uncured glue
if so, it'll fix itself unless you constantly overheat your phone (benchmarks and games)
>90% of the time it'll fix itself in a week or two,
it happens with the first batch or two of every phone launch because they didn't have enough time from screen production to sale for all of the units to fully cure.

When I look at it in line of the bottom left corner the screen looks a bit yellow. Every other corner is fine. Its not a problem it will work itself out in a few days.

I don't know if it's a glue problem.
It's look like screen problem :/ but i want to know if others users have same thing.

Yes bottom left and upper right you too ?

I am having the same issue, but i do not need to look from that angle. I see the yellow tone in the options menu just looking directly in front of the phone during normal use. Mainly in the left bottom corner but most of the bottom part I would say.

I'm assuming this is the nature of the screen technology. Mine does this looking at it from the bottom left or top right corner.

Y es i have this problem, and the colors where off, i think the gamma value is high. I hope an update because all have the yellowish screen, i dont think is glue for all at the bottom on the screen.

Mine is like that too

could you upload a bigger pic, or someone else? my htc one s looked super cold when viewing from the sides lol. that's do to amoled though.

Mine is like that too same angle, every other angle is perfect. i think its on all of them.

I didnt have this issue and i ran couple benchmarks. I did heat up slightly and the scores sucked

So you think is gone because of heat ?

I order mine, but im waiting for shipping, when I get it, i will turn on and then I'll check the angle and I let you know if this is natural.

I have the yellow tint too if I hold the phone diagonal en look at the surface.

Bleu tint web you look opposite no?
Someone know where contact Google ?

Mine is yellow tinted regardless of angle. I'm hoping this is incurred glue, obviously.
I compared against my Atrix last night & it's very obvious.
Sent from my Nexus 4 using xda premium

If I was to buy the phone in a couple of days would the yellow tint issue be solved as the phone would have been unused stock for a good week allowing enough time for glue to settle?

I'm having problems with my screen as well. Black levels are off and everything has a yellowish grey tint. I have an Optimus G next to it on the left so you can compare, as both of these phones use the same panel. Both phones are on max brightness.

Yellow tint issue on S4's screen

I have this annoying yellow tint on my S4's screen, but disappears when the phone is tilted over 45 degrees. Is this faulty ? Shall I return it ? Or is there a way I can fix the gamma through an app without rooting the phone ?

Mine doesn't look like that, sorry. But I have lag. ):

Is it just in Chrome?
Try Chrome Settings ---> Developer Tools ---> Uncheck 'Enable Tilt Scrolling'

@raqball nope this is found everywhere, even instagram and facebook.

Ah, no clue then sorry..

@raqball can you do a quick check with yours, similar to the one I did and let me know what you get ?

Go to settings display screenmode and use something else other than adapt display. Im currently using dynamic and my tint is gone.
ATT S4 Rooted. Beastin.
4.2.2

I had it on standard all this time (including screenshot) .. Putting it on dynamic gives the same result :

Damn I was hoping it was that because it fixed it for me. Maybe a hardware issue?

@stevehkim I'm not sure tbh .. thanks for the suggestion though. It's quite annoying after I realised that it exists ... Didn't bother me before I noticed it :\

I found an app called Screen Adjuster but its not really efficient.

I had this with my S3 and got used to it. I was told in those forums that this is just how these AMOLED screens are made.

My display is perfectly white though... Side by side comparisons between the Note II, Microsoft Surface RT (perfect white display), and a Sony HDTV. My S4 beats or meets them all.

Can you post a picture comparing your screen to a laptop's screen ? I just want to see how different it looks. Also, do you suggest I return it to the store and get another one ?

I would return it rather than regretting it later. It defiantly doesn't look right.

Acer 24" LCD Monitor vs S4
I'll do one of my Surface or TV later.
I made a Pure White image to use for testing on the S4, use it instead of Chrome which uses a grey color in it's UI and for some reason the S4 screen brightness dims on Chrome automatically (and you can't change it). Download it if you want to do comparisons again.

Screen pressure under front camera?

On the top left corner of my screen on the nav bar, right below the camera/proximity sensor I see what appears to be just a slight bit of pressure on the screen causing it to be slightly brighter . It's barely visible, and I'm not talking about the light bleed issue from the secondary display, because this is on the other side. It's very faint, and I can't see it when the screen background is dark or if the screen is off. It can best be seen by tilting the phone forward.
Has anyone else experienced this?

Yes I have a black bar under my front camera, proximity sensor area. If I look up from bottom to top of screen it's lighter. I had mine warrantied out today from T-Mobile

I had that issue with my first V20 from AT&T. I went to AT&T and they changed it out at no cost. I get a new one and it has a new screen 'pressure' located on the bottom corners. Makes black look a little grey in the corners.

It's on mines also, but it's a dark spot instead of a brighter spot. Right above over the status bar, you can even see it in white pics too. Wanted to send it to LG so I can get a replacement but want to know if it's fixable first.

I have this too and I wonder if it is from the CPU/GPU heating up. If you look at the ifixit teardown, that is approximately where the heat outlets. I have it on mine. It was day 1 and I was flashing some roms.

Yeah it's mostly when I flash ROMs especially AOKP or LOS. I'm thinking it's a backlight problem, because when I go back to stock it doesn't show... And it could be the CPU/GPU also because during flashing ROMs that part specifically gets warm.

Maybe you are right. I didn't see it in stock but it's super prominent in LOS. I was flashing roms for like 4 hours though. Not sure what is the exact issue.

Alright so I reverted to stock and locked the bootloader and everything. That dark spot is just as present in the stock ROM. The T-Mobile store representative agreed it was an issue. Now I gotta ship it back and wait for the replacement. Just got it a day ago man. :crying:

JFYI...have it here too.

My replacement V20 has the exact same thing?!?! Dark spot in the middle of the status bar on white (or lighter) screens. What is weirder is that it is the exact same pattern and location as the first one. It is present in both stock and LOS. I suppose I'll just wait around a year and warranty it out then because I just want to start using the phone. I included an image for people that were curious how it looked.

I'm experiencing the same thing with my V20. I can see a dark spot under the proximity sensor. Did anyone get it fixed somehow through a replacement or repair through LG?

Have any of you used a simple free screen test app to help confirm the "fault" you seem to have?

Hi Guys. I Just recently bought an LG V20 and have a similar issue. It doesn't affect day to day use but was wondering if it is normal because of the 2nd screen?

I have that same issue ^ not as burnt though but same place and shape. No screen retention at all from what I can tell, just this!
Hasn't bothered me enough yet to do anything, can only really see it on white screens.

Same

It isn't pressure spots - it's IPS light bleed. With regards to the darker patch just underneath the second screen - this is because of light differences between the main panel lighting and the second screen lighting (and again, because it is IPS, the light bleeds over if the second screen is brighter than the main screen).
