[Q] Light Bleed or Other Display Issue? - Nexus 9 Q&A, Help & Troubleshooting

Greetings! I am wondering if it is possible for this to be light bleed or is it another display issue? Basically a white bar is about .5" from the bottom bezel of the tablet. I do notice there is light bleed in that area, I'm wondering if it's the cause of the white bar? I tried my best to capture the defect and outlined it in red. It is quite hard to see in photo, but very easy to spot in person on light colors etc. I know there is a separate light bleed thread, but I thought maybe this could be another issue? Thank you for your input.

That looks like more than just light bleed. Light bleed on mine isn't as much a defined line as yours. Plus I usually don't see it on light screens. But let others answer here too

I am in the same boat as you, zetsumeikuro. I think it has to do with the cheap display panel that came with the Nexus 9 as I had the same bar of slightly-more-brighter-portion-part with my really old iPhone 3GS before heading to android. It's too bad I I can see mine really clearly too :'(

I had the same exact defect in exactly the same spot. Receiving my tablet from warranty this week with the display changed. Will see if it is really fixed.

Thanks for the update! I also just decided to send my tablet into HTC for repair for this issue. I also have super slow charging sometimes, so might as well have them take a look at that too. Please let me know how the repair worked out for you. I was super reluctant with sending my 9 into HTC cause of my craptacular experience with the purple camera with the one. Had to do the "repair" 3-4 times, it was utter and complete bull**** and chaos.

Looks like HTC repair did the trick this time! Total time from me shipping the device out to them sending it back (excluding weekends) about 8 business days. They swapped out the LCD and fixed the slow charging issue. Tablet seems like brand new!

Looks like a lot of HTC's panels for the N9 are pretty cheap. My "repaired" one has the same issue, just to a much lesser extent. The defect is on the bottom but only a small part .

[Problem] - Spots on a black background at night!!

Hello everyone,
I noticed that at night when I have a black background i can see dark spots that make you notice the color is not uniform.
This defect occurs when all these conditions are verified:
- Completely dark room and eyes accustomed to the darkness for a few minutes
- Completely black screen (like the one in the test screen by typing *#0*#)
- Minimum brightness (but can be seen even at maximum brightness).
In practice, you see lots of little dots of different sizes and shapes, always black as the background, but not the rest of the uniform color (as if they were the signs of glue that is below).
During the day with light are virtually invisible, at night using it would not normally notice, but as soon as the screen remains black for a few seconds (for example when loading a video from youtube), here they are appearing and are really annoying.
I got my phone last week, I would still be time to ask to replace it, but I'm afraid it's a problem of all devices and maybe even put the risk of receiving a worse one (with dead pixels, circles on the screen, etc.).
Someone else has ever noticed these spots? If you have not noticed could you do a test under the conditions that I outlined above?
To understand whether it is a problem of all (in which case I would avoid to let me change) or just mine.
I still have 2 days to apply for replacement, thanks!!
P.S: sorry for my bad english
Same on mine, and a lot of them... not really visible that much only with blank black screen... and sincerely when do you use your phone with nothing on the display ?
Im pretty sure those are manufacturing imperfections in the amoled production process and we cant do anything about it, im pretty sure all phones have it to some extent.
Same here... I think that its bet to just get used to it, that what i did anyway..

Yes, I have the same problem too! Just got the white version of this phone. I also noticed that mine looks like there's a small fingerprint smudge underneath the glass. These don't bother me, but what really bugs me is this faint faded line that runs up and down the screen. It looks like burn-in or something. I can't see it unless I'm playing a certain video with gray backgrounds. Should I swap it out or keep it? The one I have now has no dead pixels, but I'm afraid the new one would...
Hmmm so we all have this problem, any other witness?
Yeah same thing i was thinking im only one
/problem with all oled screens
same with mine..its a flaw by samsung. unequal distribution of glue to stick the glass and capacitive layer
Same here ...
At first I was a bit worried because I also have an LG Optimus SOL E730 with amoled, and it does not suffer from this problem.
So, the only thing that comes to my mind, is that samsung did a crappy job on this phone.
One more thing: When the screen is black, the LG appears as if it's turned off, the Samsung, on the other hand, is a little lit.

Anything wrong with the display, or is this normal in SAMOLED+?

Please refer to the picture below. Do you spot any abnormalities with my SAMOLED+ display? The yellow tint is gone after flashing to 2.3.5, but the area in the lower left is still showing a lighter tone--like a right triangle; so does a small area on the upper left. Also, the brightness (as I've noticed in other S2's) is not evenly distributed across the screen. These problems are hardly visible in normal use, but it becomes visible in grey backgrounds, and notifications area, and lowest brightness in web browser. Please let me know, thanks.

so, what do you all think? Please let me know thank you.
Mine looks exactly like that: triangle in bottom left, splotch in top right, and whole left seems a little dimmer than the rest. I haven't installed any updates & bought mine in South Africa; where did you get yours? I was honestly under the impression that AMOLED was the technology to go for, but now I'm not so sure anymore.
At first I was going to ignore the lighting defects and the pink tint in the center of camera images as there aren't that severe, but now I've found my phone's earpiece probably has a problem too. It makes a crackly noise during calls that sounds like something's loose in the speaker, so I reckon it's time to send this one back...
Update: I got mine replaced today due to the speaker problem, and the new one has neither the triangle nor the splotch. It is still darker down the left side of the screen though, maybe even a bit more so than on the old one...
I had exactly the same issues (well, not exactly as mine were worse). I had to replace it twice. Now I have one without this issues, no yellowish border and little to no banding.
The guys at the service told me that if there is any problem now, I can get a new phone right away, but considering how many people have display problems, I would rather repair this one. It's display is suspiciously perfect...

[Q] Black Fragmentation color on display - is it just mine?

So I am seeing some color issues with my SII
Not sure if it's just the way it is (because I am coming from the LG G2x which had the most amazing display you can ever imagine), or is it just my phone.
The funny thing is that even though I am attaching a screnshot, obviously YOU will not be able to see the issue (since of course, the pic itself is fine, and it is the display that makes it wavey...)
I am not even sure I am explaining myself the right way.
Wavy colorts, uneaven, almost cartoonish-like, smeary.
It is most apparent with darker shades
(U can't see it here)

Samsung's Super AMOLED Plus displays exaggerate colors and shades, and that is it's key feature. Not sure about your phone, but if you think something's wrong with your phone, go check with your service provider.

Thank you!!!
Found some info here, i wonder if mine is one of these....

I hope more members will have something to say, perhaps they have experienced this as well.
I was also thinking whether this can (hopefully) be a kernel issue or color calibration issue? I know that some kernels has effect on the colors, but I am out of my field here and completely wrong
The weird thing is that light colors are perfect. When GRAY or BLACK, it just looks bad.

I've got something similar to that.
It's not noticeable in a well lit environment but if I'm in a dark room and have a black screen on my sgs2, some blotches seem darker than the rest of the screen.
I wouldn't be too bothered about this if it was just one or two but there's one large one and a bunch of smaller ones scattered around the screen.
Thanks!
I wish I could upload a photo to show it, but (funny enough), my only camera is my phone's camera (a single student - what r u gonna do?!)
This is especially noticeable when I take a picture or when I use the Music app (pictured above), where there is huge smears of color going from the dark to the lighter.
I hate to even imagine it, but I think I will have to depart from my SII if this is something that isn't fixable. If no one else experience this, I will get a new SII
(i don't know anyone that has the SII so I have no one to compare it to)
Managed to take some pics
Hope U can see it:
Look at the bottom discoloration:
All menus with shades of grey and black present this issue (kernel problem maybe?)

[Q] Color banding for gray gradients?

After receiving my Note, everything seemed fine, although the screen had a very warm effect. I didn't mind so much, as I like warmer whites and color anyways.
However, what kind of annoyed me was the color banding that was especially evident in the notification bar (the very top and very bottom). My sister's Galaxy S2 does not have this problem, nor does my Samsung Captivate. I'm guessing this may be because of the screen resolution, but I hope it isn't because I have a defective screen. Anyone else have this problem?

200+ views and no one can comment on it? Anyone?
I have a similar issue, but assuming the picture above is a screenshot, wouldn't that rule out the screen as the culprit and implicate the actual design of touchwiz itself?
I see the same thing on the notification bar, but I don't see it on screens that appear to be specifically designed for the note. That leads me to believe they were lazy in the implementation of screens used in smaller devices. Instead of recreating them for the higher resolution, they look like they're just being stretched.

Is that a screen capture or did you take a photo using another device
Looks regular homie.

I agree this is just the lazy implementation. Open the phone and look at the dial pad buttons. There is no banding on those. They are present on the Android stock keyboard however. But I don't think it is a defect of the phone.

If you put your display on 100% and look carefully at the dial pad buttons, the banding is there as well.
Yep, I see this also on other gradiented GUis.

S9 screen with red or pink tint?

Does anyone else see reddish or pink on their screen? I see it when I tilt the screen. I noticed it a few days ago on my S9+ and now can't unsee it. Straight on it looks OK but at an angle the screen looks pink, like when scrolling through GMail or web page when my phone is on a table at an angle to me. Not sure if I should exchange and risk getting other issues. Otherwise my device has been fine. I went to the AT&T store near me to compare their display models and mine shows some pink compared to the store.

Mine show slight blue tint when tilted
The left one has a slight green tint. No AMOLED is going to be 100% perfect. Actually I think you have one of the better panels. It looks brighter and the white looks thicker compared to the display model.
Based on the number of screwy AMOLED panels I've seen, that one would probably be OK to me. My panel is yellower along the top quarter and I also consider that a keeper you can do so much worse in my opinion. In ten years they may finally nail the technology till then it's lottery.

Mine also turns a little pink if angled... i can't remember if my previous S8 also did so...
Mine turns ever so slightly blue when tilted. It's MUCH better then my Note 8 was, which turned pink at even the slightest angle.
Try factory reset, when I got mine and turned it on I saw from the boot animation that the display was white. When it finished booting it looked like it was stuck with the blue filter on. I factory reset and the display has been normal since
This can be adjusted, at least this is what I did on my S8. Go to settings, Display, Screen mode and fine tune it there.
So my wife and I each have a US T-Mobile model. Her's definitely has the pink screen issue. Duplicating the settings between the phones and the issue persists. I will be contacting T-Mobile for an exchange.
FYI - wound up not being a hardware issue for our phones. I found out that the native Android Night Light setting transfers between phones. Was able to delete,and use Samsung blue light filter settings, using Nova and the instructions here.

anyone else experiencing this on their s9+? when i tilt my device, right before the blue shift, i can se a pink/reddish hue go across the display. do you have the same thing? should i be worried? it's kind of annoying, every slight tilt and i can notice it.
I think now that I checked it seems like mine also has a very slight pink touch on it... But i dont really care and I haven't really ever noticed it.
I use black everywhere possible. Dark theme, dark wallpaper, KIWI browser with AMOLED dark turned on, so this way I save my battery, i save my screen, and black is way better on the eye
