Green blotch in screen, visible on white and grey backgrounds - ZTE Axon 7 Questions & Answers

Hi everyone
Last week I ordered the ZTE Axon 7, and upon arrival a green spot around 1/3d of the screen size is visible in the center. The screen here is slightly greener than the edges of the screen. It's only really visible on white and grey, but browsing websites with this is fairly annoying because the spot is visible all the time.
In other colors however the screen appears quite uniform.
So I returned the first Axon 7 and traded it in for a new one, but this one has a green spot as well. It looks to be about equal, maybe a little bit smaller. Is this normal for these phones? Did I lose the OLED lottery twice in a row?

I guess you lost twice in a row, yes. Maybe a third time? :silly:
I've never seen any imperfections on the screen save for some segments that were almost imperceptibly darker than others. I (barely) saw them on a completely dark room, with the brightness at minimum and displaying a dark grey background. so yeah, i dunno what happened to you

@ a tiny ant,
can you post the screenshot? With a clear screenshot I can help you solve this problem, thanks!

Display light leakage on top corners of my X1 Screen? anyone?

Hi,
When I dispay a black background color on my X1 for example the pannel screen while it is switching to a different pannel or standard pannel I see a bit of light leakage on the top 2 corners of the screen from each side. A bit white, if you understand what i mean.
Does anyone notice that?
Thanks for the info
Yep I notice it too. Probably a case of bad backlight LED placement.
This screen doesn't seem to have as good a contrast ratio (black levels) as the one on the Touch Pro.
it's rather massive. Its even visible on camera mode when you have wide-mode off.
I hate living with imperfection.
How bad is it on your device?
I have to say its not visible when other colors than black are displayed
I'm probably seeing the same thing as you are - two bright areas on the top/left edge of the display.
The light is "leaking" because the display contrast isn't high enough and the screen assembly is a bit thin.
It's something I can live with, but I do wish SE had sourced for a better display. HTC has raised the bar since Diamond and Raphael, and this one is pretty good for a Windows Mobile device, but there are tons of even better screens out there - think Japanese super-keitais.
humm.. I was trying to look for the light leakage but I can't really seem to see it.... perhaps you could post some photos of what it actually looks like?
yup, it's there
don't see any leakage on mine...
I tried one in the shop and the screen was tilting left a little bit. Also the flip was a bit loose even in closed. Any comfirmation?
I'm pretty sure all devices have the same leakage problem. Just put on a pure black screen and look for the white cones decending from the top corners.
It's because of the led's behind the screen I guess
honestly, there's very little (leakage, short of better term) if not none. If you have seen TouchPro, it leaks like crazy...
Leakage is pretty terrible, no doubt about it. Wonder if this fault is only on some handsets?

My TP don't have this at all. Virtually no leakage. Pretty much solid black even in pitch black environment. Contrast and viewing angles are excellent. One of the best if not the best screen I've seen to date. Seems like they're using 8 bit panel instead of 6 bit TN panel. The latter have terrible contrast and viewing angle as standard.
lucky if u only seen it on top corners, mine are on all corners!
i don't see any leakage... went into a pitch black room and pressed the panel button and i see no white light coming out of the corners...

then you must have a rare TP, all the TP owners in Singapore reported to have the same leakage. that's if we are talking about the same thing with regards to light leakage...
Hi,
2 days ago a friend of me and me bougt this moblie,
yesterday i gave it back to the store, cause i've seen the white
leakage on my display too, on the devise of my friend its ok.
today I'll get a new one. Hope its ok there....
Thought it was damage or so....

Maybe I'm missing the point here. Do you mind posting a screen shot of the issue so we can be on the same boat? Now you've got me curious.
I'll try and post a photo when I get home later, mine is mainly in the bottom left half of the screen and it's really noticeable and distracting when viewing something dark.
Hmmm, I've definitely noticed leakage on my xperia, in the bottom left hand corner when in landscape.
I had a Touch Pro for a few weeks before I got the xperia, and the screen on that was flawless. I might give vodafone a ring and see if I can get it replaced...
Don't forget to switch the display brightness to full to be able to observe the leakage. When I watch the Bond trailer I can definitely see the leakage on the top corners when there is a black background in the beginning. It's rather distrubing but I do believe that all devices have that in some sort of extent. I think you just have to get used to it and live with it.

Is it true - Grey color and super amoled don't go together?

I recently purchased galaxy note and had dead pixel issue with it. So I got it replaced, and now the second one I ve got has this strange light greyish blemish visible on grey backgrounds. Also when I see the screen with grey color on it the screen doesn`t look uniform where as in all rest of the colors it looks uniform. Please have a look at the attached pictures and let me know if its normal ?
Also please set your brightness to 15% or below to check your devices.
Heres the video for better view:

Honestly, I don't see any blemishes at all. However, I do see a lot of air bubbles trapped under a screen protector. Are you using one?

Yes I am using a screen protector with lots of bubbles. But do check out the video, in images its not much visible !
No issues on my Note
No issues with the screen, no grey spots no bubbles, no screen protector.
My screen is great.
Also please set your brightness to 15% or below to check.
My god that CPU is loud!
Btw, i can't see anything.

Same thing happened to me. The 1st note I got had dead pixels and dust moving behind the screen. The second one had those dark lines on grey and white color... the first one had those too but not as much as the second one. I sent them both back for a refund. Don't know if I should try my luck on a third one..
Here are some photos:

Newer Nexus 4's ALL have yellow screens?

The first Nexus 4 I received was a rev10 I got that shipped the third week after release. It has a perfect calibration with beautiful popping whites and dark blacks. Unfortunately, I had the issue where a portion of the screen would tint yellow (about the size of my thumbprint) after it heated up.
This annoyed me so I got an RMA phone and it turned out that the entire scree was an ugly yellow even without heat. This was shipped to me from jan 1-7 I forget the actual date but it was recent. It also had a sluggish vibration issue that annoyed me. I sent it back and they sent me another RMA phone that arrived on the 14th and what do you know, it also has a yellow tint to the screen. The colors are much darker compared to my original screen as well and I tried color calibration apps but they just don't look as good as the original. This phone is a rev11 if that matters.
Do all the newly made phones have color issues? Or are there well calibrated ones out there and I should keep on RMAing?
The new screens just don't look as good and are really ugly. Someone let me know if they have a good screen
If you figured that out from an extensive poll of people then I'd understand that conclusion but from 2 RMA that's just plain stupid!
My screen is white as can be, compared to One X its looks insanely good, the One X colors pop and are really vibrant though

My screen is perfect. You should maybe change the light bulbs in your place..
I have a revision 11 and a revision 10 which is going back due to speaker crackle. The screen on my revision 11 looks cooler but I certainly wouldn't have described either as being yellow.

It goes away after a couple days...
As ctowne said, it goes away after a while. It's the glue that is used to laminate the glass and display.
Mine was pretty yellow at the start, however a couple of weeks on, and it's absolutely fine now.
Yes let us assume that the two phones we received is indicative of all phones. Makes sense.

+1. Mine was yellow. After a few days, the screen is normal. Rev. 11.

Yeah mine went away within 3 days at the very most. Also, you can adjust the screen settings with fauxclock if you really want to tweak it. As long as you have uniform yellow on the whole screen then don't worry about it. If certain spots are yellow after a few days then you might have a problem.
To those of you whose yellow tint went away, was the yellow tint uniform over the entire screen before it went away?
I just got my rev11 RMA, and I've only got a yellow tint on the bottom half of the screen. Should I expect it to go away over the next few days?
Also, just holding it side by side with my rev10, I have to say, in addition to the yellow tint, the rev11 just seems a little bit less clear and a little bit less sharp. Could be because it has the factory Google screen protector on it, I guess, whereas my rev10 has an SGP crystal clear on it.
On the plus side, the light bleed is improved on rev11. Nowhere near perfect, but signifciantly better than my rev10.
If the yellow tint goes away, I can live with the rev11. If it does not go away, it will be another RMA.
I got a Rev11 one, but never had a yellow screen from the start. I guess i've been a lucky one..
When I did my RMA, my rev_11 had a more yellow tint to it on whites.. I could really tell on apps like SMS...
colors look OK and I've gotten used to it..
My rev 11 doesn't have a yellow tint.

All 3 of my phones have had an uneven yellow tint. I RMA'd a rev10 first which had a brighter and cooler screen than the two replacements, but and uneven tint along the bottom 1/3rd. My rev11's, the one I sent back and the one I have now have a less bright display, and the one that went back had half of the screen horizontally yellow tinted, this one has yellow tint in the bottom left corner. It's the least tinted out of all of them.
FTR the uneven tint did NOT go away on my first two phones. While overall yellowness may clear up, the uneven factor doesn't change.
All 3 have had backlight bleed, was probably the least on my rev10, the first rev11 had it pretty bad along the taskbar and left/right hand sides. The second rev11 has it on the taskbar, but a little less, and the top left hand side.
The displays are just pretty crappy LG IPS panels, I'm certain most people will be on an RMA goose chase to get a phone without any uneven tinting/backlight bleeding. They'll exist, but how long do you want to ride your luck changing? I also think LG have changed the display between rev10 and rev11, as as I said both my rev11s are duller.
I got my third replacement N4 today (REV 11) and it (like the previous 2) has the yellow tint to the bottom of the screen and left edge in particular. Looks noticeably brighter the bottom half too (slight though). I'm really disappointed with this as I don't think it's looking like there will be any (or many) from this current batch that don't have this problem.
Does anyone know from a technical point of view why LCD panels are prone to this - why is it such a consistent problem in manufacturing? What exactly is the cause and why isn't it prevented? Any links? I've Googled it but no results...

Screen tint and viewing angles questions and opinions please

Ok well I would like to get peoples feedback and opinions on their screens.
My story. Broke my GNote II instead of paying to replace LCD decided to upgrade with my carrier.
First Note 3 I bought was bright with nice whites and great viewing angles. But it has the dreaded pinkinsh purple screen tint issue in the lower 3rd of the screen more so on the right side. This is subtle and is less evident in brighter conditions or higher screen brightness. At low brightness and in dark environments it is particularly visible on white and grey backgrounds. Went to store to exchange and they refused given they could not see the defect. I came online here searched around and it seems this has been an issue on the GS4 and people have mentioned it on the new Note 3.
Convinced my carrier to send me a replacement and I will return the original to them. Well got the replacement 3-4 days ago. The unit seems quite different. First off the screen is overall a bit more yellow at face on viewing angles and perhaps a hair less bright at similar settings though hard to tell. The bottom is not color shifted puple. The screen color is more homogenous. However the viewing angles are completely different. Here while the brightness stays goo dlike the first when angling the screen, the colors shift to a more aqua color with minor angle variation. (guessing 20-30*) whereas the original unit has virtually no color shift at almost 90*.
I probably have to send back a unit in the coming day or 2 and make a final decision. In theory I could try to ask for a third model, however it was with a lot of difficulty and threats to leave my carrier that they relented in the first replacement. SO I likely will have to stick with one of these or return both and use my somewhat broken note 2 and wait for something else.
I am wondering if any of you out here have similar pink/purple tint issues at one end of your screen. Or if you have issues with significant white color shift when angling your screen more than 30* in either portrait or landscape. Also if good or bad can you check build date on your phone (should be under battery). FInally did you or will you replace it? Was replacement better or worse?
Also if in my shoes would you go for the better looking screen with the pink issue or the more consistent looking screen that is a bit more blue yellow.
Thanks!

I know you did and I posted some long posts there and the thread kind of died.
I have some specific questions here as well as asking what I should do in my case.
I had a note 2 and remember there being perseus kernel and with STweaks one could shift color etc and make it how you like. I am thinking going with the more uniform color model as I am sure the slight yellow tint can be corrected and the blue tint on viewing angles is no worse than my note 2 looking back so I will get used to it I imagine. That said the first screen really has great screen but the purplish pink right bottom corner bugs me on white and grey screens ( not noticeable on high brightness though) and often reading on websites etc indoors I notice it enough that it bugs me.....
So for anyone who cares here is an update on my plan. The more uniform note 3 is more yellow/green tinted whites compared to the other one that is whiter/redder. That said if I use one of these screen filter style apps that exist in the play store, I can modify the overall screen into however I like.
Downside is that it means a persistently running app to do it with whatever effect on screen longevity and battery.
Now on my Note 2 which is also yellower, I was running perseus kernel and the s tweaks app and was able at the kernel level to modify the color to get better whites. I imagine it is only a matter of time before someone can do that for our note 3. I can handle the viewing angle color shift as the device is in my hand and not on a table when i use it where it might be off angle viewing by a large amount. And even then, the tinting of white has a bluish shift and now worse than a yellowing shift my wifes iphone has off angle or my note 2 did.
Would love tohear from others and what their screens are like and or developers who might have the means of modifying color at kernel level the way Andreilux did on the note 2
I checked almost 10 note 3s bkack n white as well..and found only 1 set.it has no yellow tint and no gray lining.

You checked 13 notes and 12 of them were either yellow tint or what gray lining issue?
How did you manage to check so many.
Can you check the following. Look at the phone screen face on the tilt either up down or side to side about 30 degrees and tell me if the white on the screen turns bluish.
One of my phones does this and has the yellower whites. The other does not and has better whites but has some purplish discoloration in the lower right part of the phone.
Any one here try a new kernel from the android development sections?
Some of them talk about being able to modify screen color. Am wondering if this can be a fix for my issues.

lighter pixels on home screen with no apps default background and also bottom right w

I've had 3 s6 edge plus now the 1st one appeared to have a great screen but i didn't check properly the second had a terrible screen with the green pixels on the default background in a circular motion and the third has less of it but on bottom right on purple background the pixels colour is not uniform some seems lighter or darker than others. Is this just the nature of amoled screens that each pixel is different that you won't get a perfect screen where all the pixels under a green or purple background are even?
On full black or white it seems ok i just noticed such differences in screen quality between the devices. Is getting a near perfect screen with all pixels the same colour ie not faded or darker impossible?
I should have kept the first one cos its screen was good it was manufactured in august whereas the next 2 i got were part of same assembly batch made on same day 13/10/2015.
I just got fed up in the end as i ordered online and had to wait for replacements to be sent.
Do any of you have these screen issues on the default background of green if you look on bottom half of screen left side there seems to be this weird circular heat pattern of lighter pixels some dimmer than others. On a purple screen background the bottom right there purple is not even. I know that's not right but is it very difficult getting an amoled screen which is near perfect?
Im not sure if this is a sign my pixels are fading or wearing out or it is screen burn in the factory but samsung quality control is abysmal they let through any screen in hope the average consumer wont pay attention to uneven screen.
Is it normal to have a amoled screen like this?
As in imperfect colours pixel degrading out of the box. The purple walkpaper top left i can see that it's not all one colour and some of the pixels look faded is this standard and luck of the draw getting a good screen?
I have not done a screen test in fear of how bad it might look but on black screens and all white it looks good it's just the wall papers i can see splooges of uneven colour how bad or good is every one elses screen?
I think i notice it more because i came from an s4 so bigger screen equals more noticeable imperfections.
I didnt test my original one properly but it's screen seemed really good on the default wallpaper i duno what it woulda shown on purple.
Is this screen burn or just faded pixels from over testing out the box?
Why is it so f'ing difficult trying to get a perfect samsung screen? ??
