Well I just had this happen to me. I was playing chu chu rocket for almost an hour, then went to launch chrome. The first thing I noticed was 2 large yellow spots on the left side of the screen. I remembered see the title of this thread so I came to check it out. About 15 minutes went by now since it happened and it appears to have mostly went away. It was blatantly obvious though even though I am using the lowest brightness setting. Not to thrilled at the moment, not only am I having a nexus 10 32gb replaced because of atrocious backlight bleed and now this. For the almost grand I spent I was hoping for more.
[Nexus 4 General] FatalityBoyZahy:
My friend has the Optimus G, and I asked him if he was experiencing a yellow tint, or yellow spots showing up on the screen, and he told me he hasn't. I think only a small number on N4's are affected by this issue, but it is there.
[Nexus 4 General] Mikk36:
Did you judge by videos on the net or by your own eye?

I wouldn't trust anything but my own eyes or a proper spectrometer for comparing the color data.
[Nexus 4 General] dbdynsty25:
I can promise anyone who thinks otherwise, that the tint and spots are two different things. Warm temperature screens (yellowish as opposed to cool blue) are different than when the phone heats up, yellow splotches appear along the bottom of my phone turning half my phone screen yellow and the other half remains white. This is a defect that is getting worse by the day, not better. So saying it'll be better in a week is just wrong since it's now been more than a week since I received my N4. If the "spots are the same as temp and they'll go away" group think otherwise, clearly they don't have a phone that's affected.

It's horrible and it's not getting better.
[Nexus 4 General] nagle3092:
Mine seems to have completely went away now. Still kind of worried though that any gaming will end up damaging the LCD screen.
[Nexus 4 General] Exidrion:
I have this too, it's really noticeable when i tilt the screen downward to the right on grey/black backgrounds. However I'm coming from SAMOLED+ so I'm not sure if this is normal on this type of screen. Can anyone comment? Is it worth sending back?

N4 has a unique issue

Out of these 6 phones two are not LCD and it's clearly showing the N4 has a unique issue...
[Nexus 4 General] undercover:
Guys, i'll provide pics to support my statement regarding different colours on different ota's later. Wifey has taken the pc :)

I'm calm now, as I know for sure it CAN be improved with firmware. Not yellow spots obviously, and not extreme yellow tint.

https://www.dropbox.com/sh/a6dw9e0vyxwyqbz/bMTBd1Msch

Here. Left - pre ota, right - post ota. On quadrant and after, they are in reverse. After I updated the one with "better" screen, it became identical (read-worse). It's boxed up as it's going back, so can't be arsed to pull it out and you'll have to go by my word. Though people that know me on XDA believe me :)
[Nexus 4 General] undercover:
And here is screenshot from the phone so we can compare how it was intended to look.
[Nexus 4 General] admiez:
What you describe is normal. If you look at it from another corner it'll look blueish.

Unless yours has yellow spots that don't go away or looks significantly yellow or dim, it's probably not a defect.

This screen may look slightly warmer in color than others, and that it's probably just the gamma settings.
[Nexus 4 General] FatalityBoyZahy:
I'll try to make a comparison too if my replacement doesn't have the OTA out of the box.
[Nexus 4 General] undercover:
Thanks. Will be helpful to see if that is really the case and not just with the two handsets I have.

The one that is boxed up is going back simply for the cancellation of the contract. Other one is staying. Neither of them have what I would consider screen defect. Just to be a bit more clear on what I meant :)
[Nexus 4 General] Exidrion:
I really thought I had an issue until I saw this. This is bad, because even in his browser it's yellowish on white pages and the settings menu is quite yellow. I really tried to reproduce this effect on mine using benchmarks and full brightness but my whites are white and the settings menu only has a yellowish tint at the bottom. Bottom line is I think I was (and a lot of other people are) worrying over simply a warmer screen and was just too used to SAMOLED. I mean, if you have it like that guy MAYBE RMA it, but as it's been stated it COULD just be a software issue. I applied the OTA right away so I don't recall what my screen looked like but here's hoping it's actually a software thing. I am of course talking about yellow tint, and not yellow spots. Thankfully I've got none of those.

Just my 2 cents on the tint discussion after doing more "testing."
[Nexus 4 General] FatalityBoyZahy:
I wonder if people with custom ROMs can help us out. Maybe they don't have the yellow tint?
[Nexus 4 General] 0.0:
I had a yellow tint at first, but it seemed to have disappeared. I already made a warranty exchange. I'm not sure if I should cancel it, since it seems like its gotten better. I was thinking of comparing the two. What do you guys think?

Take a look at this:

https://github.com/mathkid95/linux_lg_jb/commit/c1be92b7967f05ed5c6ea3b9c31060617541f96a

Google changed the gamma values of the screen not to long ago, and pushed it to devices with the 13th November OTA update.

In the commit they said they wanted to fix the blue tint but instead the made the screen yellowish.

It's good to know that the screen can easily ajusted. I would be awsome if someone could make an app so we can change these values in real time.

(I already posted this link in another thread but I figured some people here might be interested too)
[Nexus 4 General] Mikk36:
Don't trust the camera, it makes the difference even stronger than it is in reality.

It takes the blueish SAMOLED and turns it into white while in the process turning the warmer IPS really yellow.

Automatic color preference ftw.

But as people have reported before, the drivers are able to calibrate the screen so custom color temperature settings should be available in mods or custom roms.
[Nexus 4 General] undercover:
Great find. Now we definitely know they changed it with ota. I want old colours back, they were crap loads better.
[Nexus 4 General] FatalityBoyZahy:
This is good to hear :D
[Nexus 4 General] manook:
Picked up my N4 today from carphone warehouse in uk. After the screen warms I have a yellow tint to the bottom of the screen.

If the tint doesnt go in the next few days ill just get a replacement.

Purchased my N7 from play store and had nothing but problems so vowed never to buy from there again.
[Nexus 4 General] 0.0:
to add on to this, i think the kernel makes a big difference in the screen color. i put the jellytime kernel on my phone, and the yellow color has disappeared. i already ordered the replacement device and will test it out on there. i'll have a brand new device again :p
[Nexus 4 General] Richieboy67:
Why return it if it is fixed? You just said the yellow color has disappeared?

So many people are getting exchanges for nothing. I doubt I will ever get mine that is on back order. I understand returning of you have an issue but you said the issue is gone..

I'm not sure if its that or not. I still need comparisons. I'll probably cancel it

[Nexus 4 General] Richieboy67:
Of course it is up to you and it is your right I guess.

Why though do you need to compare it? I mean you either like the screen or you don't? You need to see another one to find out of it has an issue? This does not seem odd to you?

sent via xda premium with nexus 7
[Nexus 4 General] FatalityBoyZahy:
They won't let you cancel it, I already tried. They said you'll have to refuse the package. I'm returning for the yellow spots on the display, I could care less about the yellow tint.
[Nexus 4 General] Richieboy67:
If you haven't already and if you still have the device could you please post an image of the yellow spots? I have seen images of the tinting but not of the spots yet.

Thanks

[Nexus 4 General] DADER:
Same of what happened to my s2 now I see permanent yellowish rainbow colored patch on the screen because I was playing on some games overheated the screen frequently

Hope not to happen to my new note2 or I will be mad of that :/
[Nexus 4 General] Richieboy67:
Oh, ok... I guess I did see it then already..

To be honest though, i would like to see pictures from everyone with this issue just top see how bad it really is. Especially from those that are exchanging.

If you guys are really having a bad issue than why not document it? Who knows, it could help us all in the future of they ever need to do a recall. It would really sick if in 6 weeks all of our screens start yellowing. So take photos people and post please.

Also, what is the consensus on this going away after the glue dries or maybe not getting the phones to hot by don't stupid benchmarks at least until the glue is set or does it even matter?

Makes sense.

So, so far we have.

Yellow tint that is not hardware problem

Yellow dots that are hardware problem

*possibly but no proof* yellow tint that is hw related

Heh, I never really saw the screen as being warm until now. It's not as warm as my GNex screen was so it never stood out to me.

I'm waiting for my replacement to arrive... there is a nick around 2-3 pixels in size in the backlight, that shows up as a bright dot when viewed from off angles. It wouldn't bother me if it weren't directly in the middle of the screen. Interested to see pre and post-update side by side.

I do feel like I'm playing a bit of return roulette though... am I trading a dot for light bleed? Glue blotches?!
[Nexus 4 General] Exidrion:
After reading this I flashed the jellytime kernel and it seems to have made the tint go away. Does indeed seem to be software related.
[Nexus 4 General] undercover:
I honestly think it can be improved even further with firmware /software updates, that is if Google bothers with doing it properly.

There will be mods, but Google have all the tools they need, all they need to do is actually calibrate the screen to its best capabilities. And being ips hd bla bla it should be quite capable.
[Nexus 4 General] Unkkut:
Just cant seem to get a good picture. But anyway...

[Nexus 4 General] Richieboy67:
OK so the yellow tinting is not glue after all? The yellow spots though, is that glue?
[Nexus 4 General] undercover:
Not sure. Some people say it's glue that crystallises, but it could be a screen burn due to point of high temperature. Although, if that was the case, people would have it in the same spots. They don't, so it looks like it could be glue.
[Nexus 4 General] Richieboy67:
Thanks for the reply man. Appreciated and I agree totally.
[Nexus 4 General] Emama:
Main Q, does the glue fade away by time or it stays?
[Nexus 4 General] agabe:
It's a very good question...LG doesn't say anything about this problem.

i have got my replacement N4, and I heated it with using 30min google maps with gps + hsdpa connection + charging, and there are spots. It seems lg just can not able (or dont want) produce good quality for google.

Other way if it's the glue and it's fade away later, than perhaps they producing too fast, and the glue can not dry, or the glue is not the perfect one type...but I don't know if any lg optimus g has a same screen issue...didn't hear about.
[Nexus 4 General] Richieboy67:
So you over heated it on purpose? !!!

Using Google Maps Navigation in a car with a charger is overheating on purpose?
[Nexus 4 General] agabe:
Not overheated, but used in a normal way. The phone was not warmer than about 40 degrees (celsius), so I think it is not too high ;)

Of course near the cpu was warmer a bit, but the yellow spots not came only there. I bet most of the nexus4 has the same screen (this is the second for me), but not everybody can recognize it. If it's cooling down the spots away, so some minutes later you can not see them.

I don't want another replacement, but an official standpoint from LG, or Google why it happens.
[Nexus 4 General] immunityx:
My first nxus 4 had the yellow spots in near the nav bar at the bottom of the screen similar to the pic above, i replaced it and no more yellow spots
[Nexus 4 General] agabe:
was it always there, or only if your cpu heated ?
[Nexus 4 General] Richieboy67:
You said used all those apps plus also had it charging for 30 minutes to purposely heat it. I was going with your words.

I am not saying it should happen but I am saying that it is common now that it is happening when devices get hot. So why would you get it so hot on purpose?

sent via xda premium with nexus 7 while waiting for my back ordered Nexus 4!
[Nexus 4 General] agabe:
I don't know if you used any phone to navigate you by car ... it's normal. Every type is warming like N4, but no other getting yelow spots.

30 minutes to navigate is nothing. 4-6 hours is normal.
[Nexus 4 General] Lazy_Batman:
I'm having the same issue as OP (yellow spots after warming in the same exact spots). I noticed the yellow spots the day I received the phone, the 21st, and they haven't gotten better. I was holding out to see if it was an issue that would work itself out.. But it's not. Shame.

I'm calling Google for a replacement today.
[Nexus 4 General] FatalityBoyZahy:
I requested a replacement a day after I received my Nexus 4. It should be here tomorrow. :D
[Nexus 4 General] lonz358:
My phone hasn't been hot since I installed faux kernel and uv'ed
[Nexus 4 General] immunityx:
Only when it heat up
[Nexus 4 General] Richieboy67:
I am not disagreeing with that. My point was just that he said he was trying to heat it. I would never put a full load on any phone while charging but that is just me.

Using all of those things would be fine but I would never do it while charging.. my i9001s plus used to get hot while charging so I would take the back off..I surely would not play a game instead..

The op was not doing any of this as normal use.He was deliberately testing to see if he would get the issue..... guess what, he did.
[Nexus 4 General] Emama:
No yellow spot,

but it seems that the very top of the screen is "whiter" than the rest

here is the picture

but I won't call for any replacement for now since I am okay with it,

It is not really noticeable
[Nexus 4 General] stuart0001:
Bit difficult to drive for several hours using navigation and not having it on charge. Of course it should be able to do this without issues other than getting warm.
[Nexus 4 General] agabe:
If you use the maps with gps in the car the battery will down within 2-3 hours, so you must to charge. When I tryed it for 30 minutes the battery was about 40-50% at the start.

Why don't you accept if you use the gps you need to charge the phone (any phone not just nexus 4)? If you don't the battery will give up..it's so simple. It is not because some "heating process", but something what normally every phone can handle without a screen probleme, and usually they reaches the same temperature or more (like samsung galaxy s2 what was mutch more warmer, but the screen was perfect all the time)
[Nexus 4 General] Richieboy67:
Did you read anything I wrote?

My only point was that he was heating the device on purpose and said as much.

Surly you can use GPS for 30 minutes without a charger. Give me a break....

Go buy a gs2 then..

[Nexus 4 General] antonizoon:
The question is not whether the OP delibrately tried to yellow his screen.

The question is whether this yellowing problem should even be occuring in the first place.

If we did the exact same thing the OP did with another smartphone, or even another Nexus 4, would we see yellowing? Is this a defect, or a common flaw in all smartphones that undergoe heavy use?

That's what we need to find out. It is not a question of normal usage, it is a question whether this is a defect.

(I'm getting the feeling that the powerful CPU inside is damaging the screen, since this chip in particular is known for overheating problems)
[Nexus 4 General] dhruvmalik:
Google fixing the YELLOW TINT (Similar to SGS II & Samsung Fixing the YELLOW Tint), due to a software update is quite understandable. The SPOT is certainly due to the Glue. Now whats in question is whether the spot disappears after the glue cures. If not, then we have a problem, if so, then LG should let the screen cure before it assembles the device.
[Nexus 4 General] Richieboy67:
Yes, I understand... It should not happen. But we all know it is an issue right now so why do something on purpose just to see of it happens? Duhhhh

This was my point.... Do you understand now? Are you going to try to over heat your phone on purpose top see if it will happen too? It will most likely..

I do not think you have seen the past I quoted. The poster said he purposely over heated his device. My point was just to not to try to do something if you know it is an issue.

I am not saying this should not happen.

This was not a reply to the op - people totally did not understand me. Not due if my posts were completely read. If this happens from the device getting hot than it is not good. I agree.. I will not run my phone while charging of I can and if I do I will try to keep usage light because charging alone gets the phone hot.. I am hoping that after a period of time this will not be an issue but i dont know..

There's are some confusing this with a change from viewing at angles. I do not think this is a problem..

When i look at my phone on my desk juste for check sms or email i'm not in front of the screen. So i see this yellow tint and it's very ugly.

And when i buy this phone, i don't see that screen can have tint when you don't look in front of it.

This is picture from google nexus 4 page

If i look my nexus like that i've got yellow tint. So where is the "Crisp 4.7” display" like they say ?
[Nexus 4 General] agabe:
You really don't understand.

I purposely try to use in a normal way !! what of course warming the phone.....but nobody was speaking about overheating except you. This is what you wrote, but it was missunderstanding from the beginning.

Hope it's clear now...no overhetaing, no direct sunlight, no any other improper use.

Once again: normal using :good:
[Nexus 4 General] dhruvmalik:
Jeez Guys... Move On.

From the looks of it with the replies we are getting, it seems to be a handful of devices rather than a big bunch. The TINT could be software related as it rectified the issue for most. The SPOT is whats in question and whether the Glue dries off or the spot remains permanent.
[Nexus 4 General] Hydro8:
How rectified tint problem ?
[Nexus 4 General] Kenneth131:
Well I would assume its a superimposed picture on the device on the landing page not actual real life use most phones yellow when at an angle to a degree depending on screen brightness. At about 30% brightness under daylight my gnex yellows also.

Its nothing major to worry about depends also on the screen temp setting but this can be changed in an update.

Got my Nexus 4 yesterday, from the second batch sent to UK.

It has a yellow hue starting about 2/3rds down from the top of the screen. So essentially affecting the bottom 1/3rd.

Easy to see with a dead pixel testing app set on a bright white background.

I'm sure it will begin to fade over time, it's not that noticeable.

[Nexus 4 General] Richieboy67:
Dude, get a grip. The post I was quoting said he was proudly hearing the phone to see if he would get the problem. Geez..i was just saying that of you are going to do things known to cause issues than don't be so surprised.

You apparently were not following the conversation so please just drop it. Stop attacking me when you do not even know what I was responding too.

Can we please move on now? How many times must I explain?

Final time- of you get yellow spots when getting very hot than it is a bad thing and it should not happen. It is a defect.

My advice would be to not use your phone heavily while charging or this may happen. And yes, it sucks. You should ideally be able to charge and use. Right now though people are getting yellowing when doing this.

Now can you see we are on the same side? We all agree really?
