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.

Blotches on an all black screen? Test yours here

Can you guys with cameras that have manual control test something for me?
Following on from a post by someone else about weird blotches on an all black image displayed on the screen, I checked mine today in pitch darkness and noticed a faint 2 inch or so of blackness on one edge of the screen along with smaller blotches. It doesn't appear to be as visible as the other poster's though but I exaggerated in in the photo so it's easier to see and settings posted below for people to check as well.
This is only visible on an all black screen. This does not exist on any of the S2's I've owned. I'll check my dad's S3 tonight when I go see him in the same way but the way to photograph it to keep the results consistent are as follows:
Stick camera and phone in a cupboard and...
Phone screen brightness: 50%
Camera ISO: 200
Camera Shutter: 15 seconds
Camera Aperture: f/4.5
Remember to pre-focus and use the 10sec timer to avoid shake
Those settings will over exaggerate the effect as shown in my photo below but it makes it easier for everyone to see as you do have to focus your eyes in reality and it's not immediately obvious unless you're in pitch darkness and looking at an all black screen.
I don't know how I feel about this though but if it's visible using the above camera settings for lots of people then I'll leave it as is.
Again, it's only visible on an all black screen so make sure your image that you load is all black and not grey or something Make sure screen timeout is set to at least a minute to avoid the screen going off!

I used this free app to notice my blotches. It worked great for me. Your method has alot of steps in my opinion.
If I have assisted you, please press Thanks button.

What free app? It's a black image with screen timeout extended. The rest is your camera settings to be able to fairly photograph the screen for everyone to compare, an app can't do that

I didn't see those nope! Thanks for the links. Seems strange though as the white S3 belonging to my dad has none of the blotches, neither does a pebble blue on another forum. My 2 S2 handsets had no issues either.
Oh well!

My first phone: (F/4, ISO 800, 20sec)
Second phone: (F/4, ISO 800, 30sec)
The guy at the store (**** Smith in Australia) was unable to reproduce the issue in-store, so swapped the phone out and said I'd have to go to samsung if I reported the same issue again. The 2nd phone still has the issue, but as you can see, nowhere near as bad... still... not very good is it.
My 2 year SGS1 had about 4 spots - never noticed any issue. The first SGS3 was definitely noticeable just scrolling through system menus at night.

That's rather bad^^ I've emailed mobiflefun with picture so let's see what they say.

Suggest you up your exposure (duration and/or ISO) to make it a bit more noticeable. Looks like you've got a fair amount of guff in the top-left corner.
:/ dodgy manufacturing.

I don't have an SGSIII yet, but I noticed pretty much this same thing on my Galaxy Note. One night I was viewing an image with an all black screen and it had these weird blotches on the screen. I had never noticed them before.

Actually mine does has it as well but I can't seem to see it under normal conditions

This "issue" is known since the SGS1. Is the leakege from the AMOLED display. One thing to consider i only have a line about half a CM in the same place where you have the circle mark. Maybe a manufacture failure?

quicker way to test.
1 - dark room
2 set auto brightness off and screen to lowest brightness.
go to phone and dial *#0*#
click vibrate test which will display black screen.
and then check....
p.s been through this in other threads here but mky local telco had 26 with this issue went to another telco and got a blue one today - and no issue whatsoever...

Backlight bleeding issues.

Anyone noticing the backlight bleeds in the dark and at low brightness? It looks pretty horrible on my unit. It's looks similar to the backlight bleed on the kindle paper white.

But yeah, these threads are everywhere.

Mine does not do that my my first one had bad light bleed I took it back my 2nd one is good almost no light bleed. You should take that one back if you can.

My G Pad looks exactly like that. I'm very tempted to exchange it but now Newegg is out of stock. =(
Sent from my LG-V500 using Tapatalk 4

Mine was not that bad, but had a blue line and significant bleed in all corners, - How common is backlight bleeding on these? Not many reviewers seems to mention it?

I'm returning my G Pad to Newegg in hopes of getting another with less backlight bleeding. I'll report here when I receive the new one.

Oh wow yeah i would return that, i have light bleed but it only drives me crazy when a game or moive goes to a black screen, i don't want to return it and get something even worst, it's a shame we pay so much money for this stuff to have screen problems.

Change the theme of the screen buttons to black and you will hardly see the leaks.

I have this issue too ;/

My tablet has a little backlight bleed in dark backgrounds in maximum brightness but I think that's normal for this screen technology. It's not that bad. Fortunately, I don't have the backlight bleed in white background. However, this is what I saw on the display on the store...

I have the same issue on mine. 7 little light projectors symmetrically placed appear at the bottom side of the screen at low brightness, 20-25%.
People say it's very common on these types of screens. The thing is how bad is that bleed effect.

Mine is like that too. Anyway if you don't see this kind of light bleed, you see it the wrong way. Set the brightness to very low and change background to white (you won't see it with black background), rotate it in landscape mode. You will see it. Those bleeds are at the bottom only. This is very weird. This is the first time I've seen this type of light bleed. Deal breaker for me. I'm returning mine.

Yeah I can see why. When you get that urge to set the brightness down to 5%, rotate it in landscape and change the background to white, you want it to be perfect. I understand....

You'll run into this situation someday. When the battery goes low and you're on Chrome, for instance. Indeed I mostly use tablet in portrait, and I admit that I wouldn't find out this issue if I didn't come here. But I'm picky lol.. So yeah. If this issue doesn't affect you then it's great.

Trust me, it doesn't. And even if someday the situation arose where I was forced to turn the brightness down to a very low level and use landscape on a white background for a few minutes, I think I could survive. But hey, you've got to do what you have to do.

Yeah.. pink green tint is still here

After having gone through s6s s6 edges edges + and now my s7 edge and we are talking about a lot of devices I am not surprised to find pink green discolorations at part of my screen anymore.
All of them had it save for one. One device out of 20+. I will probably keep this because everything else seems fine but I can't believe we are still plagued by tints. Mine is an invariable pink and green on whites and greys.

They do change on an angle but face first there are a few pink spots and a few green spots.it is not a rainbow on angle effect.

I noticed one edge is a bit pinkish than other. I had issues like this with LG and moto it's most likely a qhd display issue as I only had the issue on them types, it don't bother me that much but no phone will be perfect as long it's not standing out alot

Bottom, more pronounced at bottom right corner. No biggy but t since none else suffers from this I will ask for a replacement

I'm well aware of the issue ( I went through 7 Galaxy S6s last year and never found a perfect one), but my S7 edge is perfect, or at least close enough to perfect that I can't see any tints without going looking for them with a microscope, which I won't do.

neither does mine

I went through 3 s6s on this issue. My s7e does not have it. Pretty uniform. Was the first thing I checked.

I swear I am not going through a microscope. There is a big pink blotch on my phones bottom.
Also the phone arrived dead on battery. Wondering if that is the only one with that? Ordered straight from Samsung.

Either mine doesn't have it, or its so low for me to notice

I'm sure there will still be a few unlucky ones who have it this year, but by and large it seems Samsung has really improved the uniformity of their displays this year. Finally. Of course next year they will probably up the resolution to 4k and reintroduce the tint issues.

as far as i can say its a "luck of the draw" if your screen is perfect or not. chances are high you get no "center cut" panel, so you will have non-uniform screens...

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).
