Yellow stain on screen - Xperia Z2 Q&A, Help & Troubleshooting

Hello, for a couple of days now i.ve noticed a yellow stain (seen on white background) on the top left corner on my screen. I.ve seen that their are common at z2 tablets. My phone was not exposed to water in the last weeks, so i have no explanation for this. I am out of warranty. I am not extremely bothered by this, but i want to know the reason why it appeared and if there is any possible fix for this.
Thank you

I dont think there will be a fix for the yellow stain as its a hardware issue. I think your screen will be replaced. this issue is also common on iphones its borders get all yellowish i got my screen replaced too when i had iphone 5s. I think u need to get your screen replaced

I see.now that my screenshot didn.t captured the problem. So i searched on google an example. But my stain it.s more pale compared tot that. Not so obvious

No warranty left here. And no.sony service close-by...

its a hardware issue you have to replace the screen

Thank you

Do you know if it is somehow because of water infiltration? Or it has no connection with that?

It's a common problem affecting many devices, it 's produced by heat on specific areas, on Z1 and Z2 it mostly appears next to the charging port because of the high temperatures produced by the hardware underneath the screen. They will replace the whole screen if it's still under warranty.

Possible pixel problem on second Hero phone, help ;(

Yesterday i bought a HTC Hero (my first one). When i turned it on and toke a good look at the starting screen (the one that says Hero, and HTC), i found a white pixel, probably dead or something. I went back to the store to get a new phone. This was not a problem at all and i got a new Hero. Now again, when i turned on the phone and toke a good look at the black screen, i also found 2 pixels with a other wierd problem:
The pixels also turned out white when i looked at them in a specifica angle. Just to be clear, i am watching on a black screen (starting screen). If you look at the screen and not in a specific angle i cant spot the pixels directly, but when i tilt over the phone slightly they show up and are 2 little white dots.
After i found out i downloaded the Detect Dead Pixel app. This app can create a black screen, the same screen as the home screen. When i use this app to spot the pixels again they are way less visible than on the home screen... I can spot 1 of them a little bit if i look at the screen in a certain angle and i can see a little dot, but i cant see them that good as on the home screen. They are not visible on other colors, only black.
I really dont know what to do with the phone now ... does anyone know what this is? im a bit concerned. Thanks!
After a bit more research on my phone i firugred that the dots really arent that visible. Maybe its just dust under the screen? When i put on a black screen using some kind of Android app i can not spot them. If the pixel is lazy or dead it should be clearly visible on a black screen right? for the lazy one then.
Anyway, i spotted a other problem on a black screen:
A brighter spot on the top part of the screen (like someone is pressing on it a little bit). Is this a problem ? im deciding if i should return the phone again..
Well its entirely upto you mate - i dont know what contract you've taken out but you may have that phone for 2 years. If your not entirely happy with it i'd take it back while you still can.
Issues with the screens rarely correct themselves.
My first Hero had around 10 dead pixels and i got it replaced as i wasn't happy with it. I now have one with a perfect screen and i'm really happy with it!
Well i just returned to the store and got another phone. This is the 3th one, and it still has problems, even more then the previous ones ....
On the boot screen there are about 10 very very tiny white wierd points visible ... im getting a bit frustrated here. What is this with all the screen problems ? :S
looks like they got a bad batch in your shop... have you considered powering up the phone while you are still in the store? might save you same time and way...

I have done that, but as i said, its only really visible in a dark room with screen brightness on 100%. I have checked the phone in the store and it just wasnt visible. When i checked the screen in a complete dark room i spotted the little things again. Looks more like dust to me =\
If your brightness is 100% you should see that one single pixel immediately.
Try making an image in paint (480*320) with a black background and a single white pixel. Open that image on your phone. The dead/lazy pixel should be just as bright as the one you drew.
Also the brighter spot is normal. It's called "backlight bleeding". Every lcd screen has this 'problem'.
They are not clearly visible, i think they are smaller then pixels, but they are countable on the bootup screen. When i tilt the screen them seem to change color (might just be dust). Green etc. I dont know what to think of it, come on. A wrong batch shouldn't be the problem if its dust, then its just a assamblation error. But 3 in a row?
I'm getting a bit pissed
It's dust or a fingerprint blocking a very small subpixel. Can't you just wipe it off? But I suspect very tiny scratches.
idk whether this is possible, but it might be dead subpixels. that would explain why they are smaller than a full pixel...
Does anyone know if that is possible? it sounds like a good explaination. Dead sub pixels could be the problem. They are smaller then pixels, but beg enough to be counted (i can count over 13). Little white dots on a 100% brightness black screen.
It must be dust, its a common question among hero owners. Most of the time the things they see is dust. It would be crazy if all new hero's have up to 10 or 13 dead pixels.
Ok well, here's what happened next:
I returned my phone again, god my cash back, bought a new one at a other store, SAME problem. Swapped it for a new one again, same problem!
Got my money back and i completely changed my mind of buying a Hero.
It is not dust. Its a perfect white dot, and definately some kind of pixel issue.
To bad..
Are you sure you're not being pixel-paranoid?
When reading all of this it sounds mostly like small dust particles under the screen. And looking at the number of phones you have tried, chances are you also got one with a real dead pixel (hot pixel, always on).
But I also think you are obsessed about it. My phone also have one dust thingy somewhere which I found just like you did (pixel tester, black screen). Smaller than pixel and less bright though.
I never notice the thing under normal use, unless I really go searching for it with a black background.
So you might make it bigger than it really is and miss out on a really nice phone.
Then again, we all have our own quality standards and its good yours is a high one!
I have had a tiny dead pizel since I bought my phone. Only really see it on the bootscreen.
I was always more bother by the light you can see coming from under the keys at the bottom and near where the lcd meets the keys.
I also have 3 dead pixels but they aren't that irritating.
I also discovered them when booting up the phone, but for me, they are sea blue (all three)
Maybe it is 2nd hand stuff HTC uses on their phones?
i have about 7 or 8 dead pixels too. it doesn't bother me too much anymore... only notice it in a completly dark room on the boot up screen... probably a common problem with the lcd screen the hero uses
All Hero's have this, or will have it inevitably:
The screen does not connect fully; there is a rubber-border between the glass and the metal frame surrounding the screen.
Look from the right angle, and you can see that there is a small 1/10th mm opening. Dust will come through here, and it will get on the screen.
HTC will wipe it off free of charge of course.
It is NOT a dead pixel; these can be seen from any angle, although the color changes a little but because of the viewing angle.
Call HTC and say you have dust under your screen, they will fix it for you, free of charge.

Lucky you, i have a "dead pixel", green one.
And a yellowspot in the rightbottom corner, but that'll fade over time. (i hope)
I'm glad that the screen has a very high resolution, it's really hard to even notice the dead pixel.
I have noticed a yellowish tinge at the bottom of the display. Only really notice it when there is a white background. Is it likely that the display is somehow faulty??

I have the exact same, a yellowish spot in the bottom right corner.
I hoped it was the same problem as the iphone or SGS2.
They say the yellowspot is from the glue that they use to stick the screenlayers together, but it needs time to vaporise and should go away over time.
But I have my phone now almost a week and i still get the spot back now and then.

Sounds like bull**** to me.
I had contact with T-Mobile today, about the dead pixel and yellowspot.
The guy told me he's going to get information for me, and see if they can replace it. he'll send me an email later.
Same hear.
Barely visible yellowish (only on whites) at the bottom part of the screen.
It varies depending on the view angle.
Perfect screen here

Lucky you! I'm still waiting for update from Sony! Will see if they can replace the unit.
I also noticed that at times the yellowish spot disappears and appears back again! I wonder what it could be!!

Ah you are the guy from the T-Mobile forum (Hiraj) with 5 dead pixels.
Anyway they told me it's in stock again next week (Monday 19th)
Just noticed that my screen keeps flickering, this is more noticeable on white backgrounds, is this normal as in the auto brightness or should I be worried?

Hi guys just wanna update you regarding screen issues.
I've spoken with people on the forum of my country, other 2 guys with Xperia S and both of them got that really barely visible yellow tint on the bottom part of the screen (also, one of these guys has 2 Xperia S -him and his brother- and both of them have that tint).
Really difficult to explain it on forums (nothing compared to the GS2 yellow tint) because it's really hard to see and only visible on white/clear colors uniform backgrounds, but according to what I'm seeing it's a common issue, not a problem of a single faulty unit.
Got a blue/whiteisch pixel to the top right of my screen
They said i need to have more then 3 to get a new phone :/`
Can i fix this ?

I have the problem too. I called technical team dept from where i bought the phone, and they asked me to do a screen test over the phone. I tap the screen it shows all white, tap again red, green etc etc. He asked me if i could see a yellowish tinge running across the bottom of the display when these colours appeared on the display which i couldn't to be honest. I took it back to the shop, and i dont know if it has to do with the bright lighting within the store, but it didn't show up hardly at all, barely noticeable. It seems less noticeable in a well lit environment, or outside as opposed to when i am at home where it i notice it more. It is midly annoying, but this shouldn't be the case.
Can anyone throw any light as to what this could be??
Thanks

I believe that yellowish tint has something to do with warmth from the screen or the battery or the screen staying on for a longer time or something or something.
because when I'm using it alot, playing games, browsing, whatsapp etc etc. for like an hour. It gets more visible.
And then it's from "barely noticeable" to "hard to miss"
I can clearly see it on Grey (notification slide down) or Blue (startscreen DrawSomething) or White.

Same here. Interesting what you say. I would still like to know where the consumer stands on this issue, and if Sony themselves would recogonise if this is a somehow a fault with the display. My Arc had no such problems.
Hi guys,
I'm new here, but I was reading the threads on the S from the start.
Reading through the screen problems I was thinking about the following:
The Xperia S's screen is glued- as I know -, like for example the iPhone4/4s'. Some i4 users noticed this yellowish tint as well, and they've came to a conclusion it was because of the glue what was used to put the screens together and it disappeared after about 1,5-2 weeks.
This could explain the reaction to temperature differences too.

Weird spots underneath the screen?

Some time ago I noticed that, in some very special situations, like under direct and strong artificial/sun light and a particular angle, I'm able to see a couple of small, very faint spots, kinda similar to those left by dried moisture (like a drop of water) underneath the screen. At first I though it was my bad for putting on a wet screen protector, but just the other day I had a look at the device of a friend of mine (no protector wahtsoever), and looking closely I found similar spots, just not two but a single and bigger one. This got me a bit puzzled, so I decided to take a look at a third device, this time a demo unit in a shop, and guess what? Also that one had a similar mark right in the middle of the screen.
Now, not that this bothers me much, since you can't actually see it unless you really try (I can't even catch it with a camera), but I'd love to know from you guys if this is a common "flaw" or I just happened to grab a "flawed" handful of devices...
Yup, I have these dark patches. You can see them sometimes if you look at a particular angle when the phone is booting up. I can't see them any other time though
I can see dark patches when the screen is dimmed, especially at night, I can't see it any other times, Nokia returned it to me because they couldn't see it. So they asked to send it in again, it took them ten days to just flash a ROM....I was pissed as it is.
When the Display is off I can sometimes see some "blacker" areas on the screen. According to Nokia These are splices where the glass is somehow glued to the display.
Thank you guys, at least I feel a little better about it now...anyway it still puzzles me how this is the first device I own in years with this kind of issue, and I really had many, both resistive and capacitive, with or without gorilla and even made of plastic. I mean this isn't really a flaw, but knowing it's there annoys me. Damn, maybe I should really just stop being so OCD with my devices, it hurts

I still would class it as a fault, it makes my eyes burn.
Are you speaking about the spots which are visible in the dark if the screen is black?
I saw them when I did my screen black in diagnostics app - lcd test.
So I took a picture of "black" screen with long exposure (iso 400, 30 seconds exposure) and show it in nokia care service. Week after I got new display

Actually those aren't really "spots", it's some sort of light leak that all amoled devices have when displaying plain black: even if all the leds are supposed to be off there's still some electricity going through them. I had that on all of my amoled devices, on my Desire, on my SGS2 and on my Omnia W as well, it doesn't look that great but it's fine I guess. Weird that you still managed to get the screen replaced, maybe your unit actually had some excessive light leak.
Here I'm talking about a different thing, given that you have them you should be able to see those spots I described even with the device completely off if you keep it under a strong light and at the right angle.

Can't reproduce that. I look closely but see nothing special.
Though, as Russian proverb says - the less you know the stronger you sleep
Here is a picture of screen with the spots I was posting about.
So, if anyone have scratched screen as I had, it is a good reason to get repair
PS note that picture was taken with long exposure. Actually my eyes need to get used to darkness to see glow.

Yeah that's it, the good old light leak
Anyway the picture you took being overexposed gives the impression of a huge issue, so I guess they replaced the screen right after looking at that, even tho in normal darkness conditions it's definitely not so annoying. Good for you that you managed to get it replaced anyway
lol a 30 second exposure will bring out the worst of the display. I can understand they replaced it after showing that image that sort of tricks them because it will never be even close to that visible to the naked eye.
Completely normal for AMOLED displays.

Yellow tint due to (pebble blue) cover coating?

A few days ago me and my girlfriend both bought a Pebble Blue S3. Unfortunately mine has a yellow tint to the screen, as a lot of other users seem to have too looking at the various threads about this issue. This is clearly visible when displaying white, but also the greys are affected. The whites appear to be more yellow when brightness is at its lowest. The whites are less yellow at maximum brightness. In direct comparison to the S3 of my girlfriend all this is easily noticible. In addition, in direct comparison between both phones the front cover of my S3 looks darker than hers. So I was wondering: could it be that this yellow tint which is noticible and which is already reported by lots of people, is due to some kind of coating of the front cover? So in fact it isn't due the AMOLED screen itself, but due to the tint of the cover, which thus functions like some kind of filter?
I hope I have some time this week to return to the shop, and see if I can exchange my phone for another one...

Can you check the batch/date/country of your phone and let us know? It might be the new batch and can be the glass glue which is still not fully dried. I remember my iphone 4 32gb had this issue and i waited a week or 2 and it disappeared. Due to high demand the phones are shipped out much quicker and may take sometime for things like these to dry out.

Yep, if you tell me where I can find this information?
Yesterday evening I've been to another shop, and I've seen two other Pebble Blue devices. Both the front covers were lighter blue than mine SGS3, and the screens were more white as well...
It's on the back after you remove the battery. Also there is date/country on battery.

Same here and also Pebble Blue model...and it sucks! It literally ruins my day when you realize you shed 660 euro for...this crap of a display! Already installed Screed Adjuster from the Market (hate the new "Play store" name!!) but it's of little consolation. I think Samsung SCREWED UP big time this time and i'm toying with an idea of changing the model and, for that matter, getting out of Samsung followers as i've bee all these years. It's a shame 'cause I've been on all Galaxies ever and now they let me down.

I went back to the store and showed the problem. They agreed on me, and said it looked like someone threw coffee over it. They gave me a new phone without further discussion. The new one has a nice white screen.
Unfortunately this one has another issue; when I push the capacitive back button (and the phone is in silent/vibrating mode) I can hear a noise/static hiss coming from the speaker, which dissappears after 4 - 5 seconds...
However, the screen is way better, and looks rather nice. I suggest you go back as well and ask for a replacement.

Blue patch appears on screen

So yesterday when I switched on my phone, I found a blue patch on the screen, it was very visible on blackish backgrounds but it can't be seen on whites. Although it doesn't affect the phone, it's kinda annoying, I've only had the phone for 6 months. It tends to disappear partially at times but comes back again. I still have it covered under warranty. Does anyone know what causes this? so I can get it fixed or on the worse case, getting a new screen? I've attached 2 photos, the first one is mine. sorry for the bad quality, the other is an Oppo phone with the exact same problem.
Its happened beacuse the high temperature.If is summer in your country thats explain much.I heard for that problem.If you did use much much even in outdoors the heat reflect on screen so some patch may persist on screen.
Use your warranty.
