xperia z -spot on screen - Xperia Z Q&A, Help & Troubleshooting

hello.
from about two weeks I have Xperia z
recently in the lower left corner of the screen, began to appear a strange spot (visible in bright background, such as the white
background, the stain is "yellowish" the gray background is just a bright spot;
becomes more evident usually after a while (after warming up?)
I called the sony hotline -do not know the problem
sometimes it does not resemble a known Xperia S issue ?
ps display mdy70, phone from orange
ps sorry for my English. it's not my native language

what is this Gray background?
did u use any app for screen test?
anyway use this code for testing screen quality;
*#*#7378423#*#*
i saw problem in some pixel with a screen test app> like dead pixel
but after i use stock android test menu i couldn't see any problem
:good:

thx for response.
the color is gray
jpg in full screen
* bottom of the screen is hidden from view by the buttons on the screen (in service mode) but the spot is still visible
the white screen (white board jpg / LCD test pro app) is a yellowish spot-intensity depends on the time you use the screen, after you turn on the phone after a long break the stain is very little visible
regards K.

Isn't that the yellow tint issue that the Xperia s suffered? You might need to get it exchanged if it doesn't go away.
As the phone gets heated up it causes the glue between the screen to melt? I forgot it was sth along those lines. Thought they fixed it.
Can you post the production date? Should be sth like 13w10 aac at the bottom of your phone.

hello after the break ...
today I received new c6603 from the operator- the same date of manufacture, the same lcd manufacturer (jdc) etc-but this time zero "bad" pixel(in previous I have 1), and at this moment no spot on screen...
in the previous xz -authorized sony service confirmed the presence of lcd defects.

[Q] Green Line along the edge of the screen?

hmm,after a month of usage,just today i noticed a very thin green line along the left side of the screen,only(mostly) visible on white color background...I did alot of surfing today which of course the browser and the sites mostly have white background,maybe thats why i noticed it today and not before...
anyways,its only on the left side of the screen and looks like it is at the just beginning of the pixels and its very hard to see,but it is there...
i did a very little net search and it says it is normal due to our screen matrix,but im asking just to be sure
thx
Doesn't sound normal to me. Any chance of a pic? I'd recommend taking it for repairs before it gets any worse.

after some research on this forum i got this from a senior member on another thread about the amoled:
"It caused by pentile matrix used in none plus samoled screens. Each pixel is made of two sub pixels one green and one either blue or red. The green sub pixel is always on the left side so the left side of the screen will always have that green line."
I should of checked before making this thread,sorry...anyways looks like it is a an amoled feautre
Yep I have it also...Noticed while back but doing a simple google search found out it was common thing

I only just noticed this today by looking hard and it still doesn't bother me lol.

so,i took an extensive coffee break today and went to my local official samsung retailer shop,where i bought my phone since i wanted carrier free(Sim-free) device...i checked the displayed s3mini there and it has the same very thin green line on white background(i used the stock browser)...Also the manager was kind enough to open a new s3mini right out of the box,we put the battery,powered on and same story with the thin green line on the left side of the display...(ahh the 4.1.1 ripple effect,i miss it since its gone on the 4.1.2 upgrade
Anyways sometimes i get carried by this peculiar stuff,so from there i went to my carrier(VIP) shop and checked the displayed unit there and of course it has the same ultra thin green line
So,its an amoled feature,nothing to freak out...its very very hard to notice,especially if you are outdoors where there is plenty of daylight
cheers
Wow now I can see it also on mine but if u had not sad anything I would not have noticed!

Sorry m8,my intentions were not to spoil the experience with our phones...Maybe i should just delete the post..But i think people should be informed about what they are buying...its not a big deal anyways
Update your subject title with (solved) so it doesn't seem like an ongoing problem :-$

Solution to the Green Line on the Left Side
On your Galaxy Device:
Go to: Settings >Display >Screen Mode
Under Screen Mode:
Scroll down and you shall see Advanced Options.. In that make Green 0(zero)
This will get rid of that Green line.. The same method will work for any RGB Line that occurs on the side of your Galaxy Device

HTC One screen issue

Does anyone have this problem where you can see these very light faint horizontal brownish or grayish line from top to bottom of the screen? Each of these horizontal lines are like a pattern of bars, each of these bar consist of 2 lines from top and bottom. It only shows clearly when in a white or brown color image, example, Google Play store, white webpage background and setting menu.

You can't. A camera cannot pick it up as the lines are very fine.

Yes same here. I was gonna post about this, but held on it since I had a feeling thats just how the display is (as explained below). Glad its hard to see unless at certain angles and lights.

[Q] Screen issue, please help!

Hi All,
I've just purchased an Xperia SP and I noticed something on the screen that makes me consider trying to return in, but I'm not sure whether this is actually a fault in the device or not.
I noticed that there are evenly spaced, faint lines running vertically across the screen from top to bottom. They are especially visible over light backgrounds, and although not that bad, they are definitely there. I compared the screen to that of my previous phone (Arc S) and it doesn't have these lines.
Could someone tell me whether the lines on my new phone warrant a replacement, or if this is the way it should look?
Thanks in advance!
Tom

Light bleed

Does anyone get any inconsistent light bleed at the bottom of the screen, I know light bleed is normal in current screen technology, i'm just curious, top and left/right side looks fine on my unit, it's just the bottom, I will not return my unit as it isn't realy consider a defect.

Come to think of it, you can only see it if you are on the lock screen using the white, rose or white background, I did notice this as well on the other units before I chosen this one as my final one.
I have a slight light bleed on the bottom right hand corner. i only notice it if i really look for it,. it only shows on brighter colors. Only thing im afraid of is it getting worse.. my xperia z3 compact had the same issue, but way worse. it was yellowish, so i think it was the glue melting or something. whats crazy about the z3 compact having the issue is; i bought the phone with a cracked display and sent it to Sony to fix/replace everything that was broken and i received it like that. i havent owned one IPS display device without having light bleed.
PS. i have the xperia x, non performance.
No light bleed here. You're talking bottom of screen above speaker?

im talking about the very bottom right part of the bezel. think of it as if you had a white tool bar at the very bottom, you would notice it on the right edge of the screen, on the bottom portion. it goes up about half an inch. I would get it replaced, but then id be without a phone and i only really notice it if im looking for it.. still bugs me with my OCD though

I'm looking and don't see it. My only issue which doesn't affect functionality and that I ignore is that my front camera isn't quite centered in the opening. It's slightly shifted to the right. It's weird because when I check the phone I don't see any gaps even with a flashlight. But no big deal.

All I have is a row of very faint light dark light dark light....... along the bottom from one end to the other, I think its just the row of LED along the bottom, I have check many units from friends and display model, they all have this.
But since it's very faint and only shows with white or beige background, it isn't important and I don't think its a defect.

If you open diagnostics, screen test and look at the full white page.. Do you notice light in the bottom of each corner? (not the top ones, but bottom). I just got my replacement because it was bothering me on my last unit.. this one has the EXACT issue, in the exact spots (more noticable on the right side). a pure black screen looks perfect though? i just think that is so odd.
also, i do notice the black strip you're talking about, i think it has to do with those leds being visable

This issue isn't bothing me, but there is a problem I have noticed, not sure if it was their during my purchase or it suddenly just popped out, but in a white screen I do have a patch about 3mm-4mm which is white that shows up, it's much whiter than the actual screen if you have white and also shows up in a biege background, I think it's what people are calling a light bleed I guess, it's on the bottom left corner about 10mm from the left and 15mm from the bottom.
I took it to a local xperia service center yesterday, and they say it could be two reasons behind it, either something is pressing on the back of the screen or a defective LCD panel, either way they say my warranty covers it, it's a shame as It was sort of a perfect screen free from any pixel problems that I find with many xperia phones.
I will have them to service it after my holiday in early October.

Excuse my edited picture above, here what im experiencing. looks way worse at night. more of an OCD thing, but it does bother me that i paid full price and whatnot. the light bleed actually goes across the whole bottom, not just the edges. just harder to see in this lightning (im at work)
