Cloudy area displayed on white or light screen - Nexus 9 Q&A, Help & Troubleshooting

I bought my N9 32GB white from Amazon Warehouse on Feb. 17. It was the second I'd ordered. The first had a defect (bent frame). All has seemed well with this--very minimal light bleed; no dead pixels; recessed but clicky buttons; no squishy back--in fact, very solid. For the past two weeks, I've noticed a cloudy area about 1"x1" just below the horizontal midline near the center in portrait mode. It looks like a smudge but remains after I wipe. It's particularly noticeable as I scroll white-background screens. I even changed my Tapatalk app to dark mode to avoid it. I've tried to get a pic of it, but it doesn't show up well enough, if at all.
I came across a similar situation of someone seeing dark areas on light background on his LCD panel laptop after he had sat on it. It was reported that applying extreme pressure to an LCD screen could result in this phenomenon. I have not applied any pressure to the screen, but as it is an open-boxed item, it could have happened.
I need opinions from those who know about these things as I know nothing. ATM, I'm trying to train myself to scroll a page from the center so that my fingers hide the "shadow" which is also what it looks like.
Thanks

Hi, ritchea...
Sounds like you've not had the best of luck with the N9, this being your second one.
From your description it certainly sounds like a hardware defect with the screen. A manufacturing flaw perhaps, or something happened to the device whilst in transit or in storage at the warehouse
If it really bugs you, you should get it replaced.
I'm a little OCD about this kind of thing, and no matter how much you try to convince yourself it's nothing and to avoid looking (at the screen flaw)... subsequently, you spend all your time **thinking** about not looking... And eventually you look.. And wished you hadn't... if that makes sense. It detracts from your enjoyment of the device.
Rgrds,
Ged.

I'm a bit (more than a bit, really) OCD. I've owned over a dozen devices but never experienced this so I also assume a defect. I just needed to know if this is a possible defect that is known-especially when trying to get service.
EDIT: As this thread had had over 200 views, I'm throwing more info out there to see if anyone has any further insight.
I factory reset the tab --all stock except for relocking it. Darn if the spot didn;t seem to disappear. Then it returned. At that point, I decided to revisit the back. Hmmm. There is a little give in it--not spongy, but when I applied some pressure, I heard a sound in the middle of the tab like adhesive reattaching. (I've looked at the teardown and know that a lot of tape exists but not from the back cover to the rest of the tab.) I looked at the white screen, and again, the cloud was gone. In a few minutes, it reappeared. So, I firmly rubbed the mid-back and the cloud disappeared. I've now tried it over a dozen times (after restoring my nandroid), and applying firm pressure to the back always, but temporarily, removes the cloudy area. Can someone say what's most likely causing this? (I know it's faulty hardware, but I mean, what is happening to the screen when I apply pressure? Maybe a bubble in a layer somewhere?
Because of the camera, I don't want to get into taking the back off. I chatted with HTC to make sure my Amazon warehouse tablet was covered, and was told that it is even though (from the CSR) Amazon is not an official HTC retailer.

Got a lemon?

Haven't really seen any posts on this, so maybe I just got a lemon...
Got my Flyer last night and first thing I noticed was that I had some light-bleed at the bottom of the screen in portait mode. 2 greenish blobs to be exact. Also some more slight bleed along the right side from top to bottom. I cranked up the brightness to just how bad it was, and lo and behold, found 3 stuck pixels.
Examined it a bit more and noticed a slight gap with light passing through along the bottom edge, where the screen meets the bezel. And last but not least, also a jaggy scratch on the aluminum itself.
I'm going to take back to BB and exchange for another, was wondering if anyone else had flaws like these? HTC build quality is usually pretty good, so I was surpised to see this on mine.
Sent from my HTC Desire HD using XDA Premium App
There seems to be some different issues depending on which version people have bought (EU/US/other, Wifi only/3G+Wifi).
I have EU 3G+Wifi,32GB version, my screen and the exterior was perfect, but the touch sensors are totally irratic. Sometimes the far most left edge doesn't respond in portrait mode, some times it seems to respond to nothing at all, just flicking the home screens around, pulling the status bar down, launching shortcuts, or typing random stuff, even the soft keys are buzzing and active when this happens.
It actually did this from the first time I powered it on, and it took me 30 mins to get through the first few steps to get it up an running because it kept pressing the wrong places and quite often hitting the back soft key. I tried a factory reset, it helped slightly, tried recalibrating the keyboard, tried various hacks found around these forums, nothing helped. It seems worse in landscape mode than portrait.
I am getting it replaced by Amazon, which is quite nice since it also seems to acquire scratches very easily, even using the capacitive end of the pen has left tiny tiny marks. So, I ordered some screen protectors just to be on the safe side.
No issues with mine, sounds like you just got a dud.
No issues with my and is 16 gb wifii
Ok, just exchanged and got my 2nd one at a different BB... more problems.
This one also has some light-bleed at the bottom, but not as bad as the 1st one. Also has 2 stuck pixels, you can see them perfectly using one of those screen tester apps. And lastly, the volume rocker is loose, when I pick up the tablet, it makes a rattling sound.
Also weird, when I first booted up, had a default wallpaper of a blue skateboarding Android on a dark background... was not the normal default HTC wallpaper, wtf? lol. The box was sealed shut, had never been opened. Weird.
So back to the store again tomorrow, gonna exchange.
Edit: Tried out one of those stuck pixel fixer apps and didn't work. The stuck pixel is red, can see it perfectly on a dark background. I'd be willing to keep this one despite that, but the loose rattling vol rocker is driving me nuts. Argghh!
Ok, I guess 3rd time's a charm because I got Flyer #3 today and seems to be perfect - no dead/stuck pixels or rattling vol rocker! Everything seems solid.
Interestingly, on #1 and #2, the 3d carousel effect never worked at all. But on this one it works fine. Really surprised I had to go through 2 bum units first to finally get one that wasn't defective..

Blue Vertical Lines In Sunlight

Hey guys. Was out and about the other day and was using my phone and as I tilted the phone down out of the glare of the sun I noticed some weird vertical lines on my screen. Each evenly spaced same colour etc.
I can not replicate the effect unless there is large amounts of light or im outside in real light. BEAR IN MIND ITS ONLY VISIBLE AT CERTAIN ANGLES.
The lines don't appear on any pictures or hinder the video. They ar only visible during sunlight.
What im wondering has anybody else got this I will say issue. Or any insight as to what it could be? If there's a problem Carphone warehouse will want to repair it and not give me a swap for a new phone. What light does anyone have to share. Or am I just being paranoid?
My Titan is exactly the same, I think its just the way the screen works and is nothing to worry about.

I've got mine from Carphone warehouse. Haven't noticed this yet. They will replace it for you within 28 days. Else it goes to HTC for repairs. However, where did you find this sunlight? It's been so gloomy out here. BTW as mentioned above, this could be just the normal screen behaviour. The other two issues with screen that have come up so far are - the pink dot in the middle and grey keys visible on white background. Nothing back from HTC.
Hold your Titan with the screen directly facing you, at about 3/4 arms' length (as in, just sorta normally with your elbow bent a little) under diffuse light, with the phone powered up and the screen off.
Then tilt the phone backwards. As you get about 3/4 of the way back, you might see a regular pattern of thin stripes running up and and down on the screen.
They are not visible when the screen is powered up. I think it's just a normal part of the way the LCD panel works. As an analog, on my Dell Venue Pro, I could see a grid of dots under its AMOLED screen when looking closely at an oblique angle similar to as described above.
I also have a matte finish screen protector on my Titan, which might be making this more pronounced. In any case, it is absolutely *not* happening when the screen is powered up -- even in black areas of the screen.
Hmmm... Maybe it's a future charging grid.
have you guys noticed anything new in regard to htc amaze blue lines. i just go the phone a week ago and i have been noticying the same things. any new info thank.
My Titan also has these blue vertical lines, and it is seen only in daylight with screen off.
I see the same too but I thought it was from my screen protector...

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.

[Q] EVO LTE Screen Flex/LCD Ripple Issues?

Unfortunately my OCD kicked in and I returned my first EVO LTE as it had peace of dust under the screen and slight light leakage at the bottom. Other than that my screen never had any flex or ripple issues and I am regretting that I took it in for an exchange!! My 1st exchange unit had a pixel that was stuck in the on position and had seriously bad LCD ripple effect. Took that back to a different Best Buy and the second exchange also has this same LCD ripple effect. It is most noticeable on black screens if you lightly press around the sides like you are scrolling up and down a web page. It can also be scene on the home screen. There are several videos of a One X having this issue. Example: http://www.youtube.com/watch?v=1DmLNSiNT24
My question is, how many people have this issue? I am crossing my finger and hoping I can get a unit again that doesn't as I truely am pleased with the other aspects of this phone and can deal with the other small little hickups of a new product launch.
I have none of this.
my OG Evo had this after I replaced the digitizer. i assumed i did something wrong since the one before it did not. no issues on my lte
Limited sample of responses so far, but seems to be looking more positive than I expected it to be!
Maybe I have a better chance of my next replacement not having this issue than I thought! I hope it was just a bad batch for this area and the next shipment will be better!
Had same ripple issues
Hi..well I got my evo lte on a pre order. I ve had all the evos thru the last couple years and the LTE is a very good phone. I noticed the exact same thing,when I would gently push or tap on the screen it would have clothes of light that we're very bad,and on black screens that was even worse. I called sprint and they told me to go to a store to exchange it. I went to the store and the manager was awesome we sat down and he brought out 5 brand new EVO LTE s for us to try. At his amazement they all were as bad if not worse then mine on the ripple effect. I have a galaxy 2 touch and when we pushed on that screen no matter how hard it showed no signs of light bleeding or rippling at all. He didn't know what to tell me but did they say the screen on the htc should not do that at all and it might be a bad batch. To me it seemd the glass on the LCD screen didn't bond well with the glue they used,and when you pushed or tapped it would go down into the LCD screen. I know when you push directly on a LCD tv,computer screen it will give you the same similar effect. I called sprint and told them I was returning the phone and the lady in the return department told me she has had a few calls about people wanting to return the phone because of this issue. I really like the LTE,but couldn't put up with the screen issues. I am going to wait till the galaxy 3 comes out and also by then check out the EVO lte again to see if the problem has been fixed.
Sigh first off mine does this but I have to apply more force then is needed for the phone to register the touch. Second off WHY are you pushing with any kind of pressure to even do that? Now if you're just touching the LCD and it is doing this I understand. Also even in the vid it looks like more force is being applied as needed but not as much as I have to apply? That being said if you think sgsiii will be better well it will cause it doesn't use a LCD lolol.
Edit I think this is to have gorilla glass 2 which is thinner so chances of this happening are going to be common I'd assum of you push down on the screens lol.

From my experience I am not applying any more pressure than I would use normally. That is the only reason I noticed it. I was typing in my numerical pass code on a black screen and saw the ripples. I then did further investigation. The video might not be the best reproduction of how you get the problem under normal use, but it does show what the problem looks like. My first phone I actually used more pressure on trying to figure out what the dust spot was and never had this issue occur so had no clue what I would run into with an exchange. This is a production issue on some LTE's and One X's. The below comment was posted in an article on the One X in April. I just think some phones are much more noticeable than others and who knows what this issue will turn into over the life of the phone.
Source: TechnoBuffalo
"Three separate models provided by HTC, and one by network Three, produced the issue, CNET UK said, meaning it may potentially be widespread. However, Daniel Hundt, creative director at One & Co., HTC’s design consultancy, said the company would never “let that ship.” Hundt added, “maybe this is not a shipping build,” referring to a unit CNET UK writer Natasha Lomas demonstrated the issue with.
TechnoBuffalo’s own Jon Rettinger and Todd Hasleton didn’t notice the issue when reviewing the One X, and chances are good the average user won’t either. The device really is one of the most beautiful phones out there. It also provided the best Android experience we’ve had yet, so this “screen flex flaw” issue shouldn’t deter folks from picking the device up. Still, we reached out to HTC for comment, and will update as soon as we hear back"

This is not something that will push me to an S3 though!
Ok well then that's a diff story and I'm wondering if it due to the glue not curing by the time it got to you... Or a lack of glue. Since the glue has apparently been a problem this time around for HTC lol. And glad to know you won't defect to the sgsiii. The one thing I don't understand is why Samsung uses the gn as a beta for their sgs line. Same screen on gn and sgsiii but its to be slightly better.(only cause they used the gn as a test)

Yep, glue on this current phone has the screen slowly getting white. Started out kind of yellow and now most of it is white with the bottom section still a little yellow. Going to give it till Friday to see if anything improves and if not I will test out the new shipment at Best Buy and try my hand at another exchange.
Update:
Went back to Best Buy and we opened up and looked at 5 different phones and EVERY single one of them had this issue. Some worse than others, but it was still apparent.
Not giving up though, trying a different store today to see how that works. I know my very first phone did NOT have this issue, just had a small speck of dust and slight light leakage..... I SOOO wish I had that phone back! Should have never returned it.
Update on my OCD - LCD Flex Issue:
5 Different Best Buys in two different states. Every phone I have tested had this issue to some extent (18 different phones tested). Some worse than others. I now believe my original phone had the issue, but was just less noticeable. Also, the screens normally do start out with more of a yellow tint from the glue. This mostly goes away after a few days of high brightness use, but sometimes a slight yellow band at the bottom remains. I think HTC doubled up the glue to help with the light leakage issues they are known for in the past.
Current phone has white balance closer to a pure white than a light yellow. (no yellow band at bottom either. This screen still has the flex issue but needs medium/medium heavy pressure to see on a black screen. I should never have to press that hard on anything to ever notice it. I am almost perfectly happy now, only bad thing is it does have one stuck pixel at the top of the screen (can't be seen on Pink, Red, Blue or Black, but is apparent on Yellow, Light Blue, Green, White and Gray). Would have never noticed it without the dead pixel test. I would rather have that than have it sensitive to the flex issue and any yellow tint to my white screen.
So, if you have not noticed the flex issue, then DO NOT look for it or try to reproduce it. You will most likely find it. Not a show stopper and should not be reproduced under normal use (Except for the few bad eggs that are really sensitive).

Backlight uniformity?

I love my Xperia Z4 Tablet. However the backlight is noticeably dim on the bottom (when in the default landscape position) or the left hand side when in portrait (volume/power button facing up). It is most noticeable in portrait mode when there is a white background (Kindle, Chrome and Instagram most notably). I am willing to live with this issue, but was wondering if anyone else is seeing any issues?
For the price I paid, it would be nice to have uniform backlighting. But I am worried it could be worse on another unit. Expansys has offered me an exchange or refund but there is a delay in availability now that the first lot has sold out.
No problems with mine
I am sending mine back for an exchange. I miss it already
Now I noticed that too. The difference is really small, but it's there.

Hopefully my replacement isn't any worse than the one I just sent back. It was as bad as I could handle.
Interesting, the same with my tablet - seems to be a general problem
I don't know if I should return and change the tablet...
can you make a picture for us? I dont know what you mean? my backlight is perfect - no bleeding and no clouding )
I'm sorry, but it was not possible to make a picture where you can see this.
However I can only see it on white backgrounds - the first centimeter is slightly grayish...

It is not a hardware problem. I see the band only when the bottom menu appears. It looks like the transperancy issue with that menu layer.
Mine looks fine, just hope it is not something my eyes just don't notice, but others do.

No, I think it is a hardware problem - if I turn the tablet from landscape to portrait mode, white backgrounds are gray on the left. Btw for me it's only visible in portrait mode - in landscape mode the menu bar on the bottom is usually black or transparent...
It is definitely a hardware problem and it sounds like the backlight is weaker on several units on the bottom (when in landscape) or left hand side (when in portrait with power button facing up). It is a shame as it is very distracting to read on anything that doesn't have a dark or black background in portrait. Still waiting for my replacement unit As long as the replacement isn't worse, I will likely live with it as I really enjoyed (and miss) the tablet.

Try anything with an all white background. If you open Chrome with no web pages loaded and the new tab page up or Kindle with a white background and hold the tablet in portrait, you might see uneven backlighting on your left or right sides depending on the orientation.
Backlight direction is notable
Got my Z4 tablet yesterday. After reading some issues with the backlight I checked this at my device and can see there is a notable uniformity.
If you hold the device with power button upside, then one can see a thin bright line from the backlight LEDs on the left side, while the opposite screen edge is slightly darker.
It looks like the screen is only backlighted from one side. For the normal usage it is not really annoying, but it is there and you would see it, if you take attention for the issue.
Do other Z4 owners have the same effect?

I have the impression my Amazon Z4T packages was already a replacement from someone else. The box made used look, some scratches and one corner had a ditch.
It wasn't sealed in any way. The charge adapter cable looked out of its the small box. The screen protection layer made the impression it was reattached, a lot of air bubbles were included.
Can someone describe how he found the delivery when unboxing it?
Was it sealed?
I also consider a replacement, if the screen issue is not a general construction feature.
Oddly enough, I purchased mine from another supplier, and also felt the item had been handled if not used. USB cable was out of wrapping and screen protector had signs of being removed and re-applied. I received mine the day after they were available for sale. I am hoping my replacement looks like new and has minimal or no backlight uniformity issues.

Hopefully you get it soon and can report here the condition of the replacement.
I have 14 days left to send it back to Amazon for free.
Please also describe how it was packaged.
Are there any seals or blister foil?
I can't believe Sony delivers an open package to retail stores.
Unboxing videos on Youtube don't show this clearly.
Thanks in advance.

Can someone describe how he found the delivery when unboxing it?
Was it sealed?

For me:
Not sealed.
Box in perfect condition.
Screen protector had a few bubbles, but not that many.
It was perfectly even on the tablet, edges protector = edges tablet.
Charge cable was in box, but it was wound a bit loopsided. But I think it more likely that it came that way - besides, how many people do even need those cables nowadays? Even if they need them, they likely will not use them when trying the tablet out.
Charge of 65%
Tablet itself:
I couldn't see a backlight uniformity issue, tried it with a white background with 100% luminosity in a dark room. Compared to the Z1 Tablet the screen looks a LOT dimmer in the dark, but I suspect that is more because the Z4 has some auto-dim function there. In bright light the Z4 screen looks slightly brighter.
What I noticed is that the speakers produce a fair amount of white noise. At 10% it is very noticeable, at 50% I do not hear it unless it is a very silent scene and I am concentrating on it. Somewhat annoying and IMO not something a tablet in that price range should have, but not annoying enough for me to play replacement bingo.
My seller is out of stock with a new batch due next week. I'll let you know when it comes. From what I can tell, Sony products are never fully sealed.
