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...

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.
There are a few threads out there that have touched on this issue but none as far as I can see that deal with it directly.
The problem comes when you display a pure black screen in low light conditions. It shows that the AMOLED screen is actually grey / blotchy / cloudy instead of being pure black. Initially I thought mine had fingerprints or smudge marks on it, until I realised they were behind the screen. I guess I might have got a phone with a screen that was replaced, but the amount of people who have also reported a similar issue leads me to believe that it might be a manufacturing default? The blotches / clouds on the screen dont change, but exhibit a random formation as one would expect from a defect. It is also possible to see a very faint outline of light running along 3 edges of the screen.
Naturally this is a situation that doesnt reveal itself very often. But I as I use my phone a lot at night, especially reading ebooks or watching films, you start to notice it more and more where you have large expanses of empty black screen.
What I would like to know is how many people have got screens that exhibit this behaviour and how many of you have sent them in for service or had them replaced?
Is it a common issue and something that is to be expected from this type of screen?
You can test if yours has this problem using 'Screen Test' (its free) from the market place. It cycles through solid colours and patterns every time you touch the screen.
Just do it in bed with all the lights out P), give your eyes a few seconds to adjust and see what your screen looks like displaying pure black.
I'm very interested in everyone's experiences and any input or information you have.
Thanks everyone in advance!
ps: I came from a ZTE blade (OLED) which has a uniformly dark grey background when displaying pure black. I kinda expect this as it is a budget phone (albeit with a better than budget screen), but I didnt expect the SGS2 to be quite as bad.
Use "screen adjuster" from the market and set contrast to -60
i have never seen this black low light screen defect. but i am asking you people if any of you have noticed that ugly blurry shadows which are perfectly visible with low light, on white backgrounds especially. they look like marks above the actual display and make high quality images look like low resolution.. it is annoying as hell..
I have this. Noticed it one night when my phone was switched off and charging.

I also have this, noticed the first evening i used the phone...you can notice this during the screen wake delay, or when in a call if you cover then uncover the proximity sensor...don't know if it's a defect but sure it bugs me, i know many won't notice it and will say they don't have this...i will add that if u look carefully to the screen dimmed at lowest brightness in a low light (buy not dark) environment, like early morning, you'll see some "interferences" behind the image, also the darker/yellower left half screen is still visible in these conditions
These things shouldn't be there in a 500€ phone
Sent from my GT-I9100 using XDA App
Thanks for the feedback already.
@elmerendeiro: I have also noticed some 'interference' lines on my phone from time to time. I did a bit of research and it seems when your phone's brightness is set around 25 - 30% it picks up interference from either the wifi or 3g radio. Notch the brightness either above or below this level and you wont see it anymore.
I agree with you when you say we shouldn't be having these problems on such an expensive phone.
It bugs me too - if it wasnt for this i'd have to say it would be an amazing phone
Might give the Samsung service center a call and see if its something they're aware of and if they are replacing screens with this problem?
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.
So, I picked up my new V10 today, and I noticed something odd. It appears that the upper left corner of secondary screen has a problem with the Backlight. Just wanted to see if anyone else is noticing this.
It's most noticeable when the second screen is running with the main screen off, especially when there are notifications coming across, the upper left side of the screen is over-lit. Please see the attached couple of pictures for example. (The first picture is hard to see, but you can see the brighter corner on the second picture where I have an email notification). It's also noticeable when the phone is in use and both screens are on.
I'm just wondering if others are seeing this or if it's possible that I got a small defect from factory.
The secondary display does 'bleed', as mentioned in a few youtube reviews. Mine also bleeds. Apparently this is normal but definitely not appealing.
Mine does as well. Only noticed it in my pitch dark bedroom last night.

It's not a defect, just part of using backlights. Look up LG G2x backlight bleed, that was a whole different ballgame, lol.
I'm only seeing that bleed in the dark until that screens dims a bit then the bit of bleed dissappears. I've never seen what you have in your picture.

Yours looks very excessive. In normal viewing conditions, the backlight should not ever be that noticeable. The only time I ever see the backlight on my V10 for the secondary display is in a completely dark room when the screen lights up a little bit because the phone was moved or something. But in this case, the backlight is leaking into half the screen because of how backlight bleed works in an LCD - i.e. it is not a hotspot like you have.
When I got my first V10, it had a hotspot in the upper left corner of the main part of the display. I noticed it immediately but wasn't sure if it was a defect or not. Compared it to the demo model and the salesman agreed, so we swapped it for another V10 right on the spot - no issue now, the screen looks beautiful and the secondary display and notification bar blend PERFECTLY into the bezel during use. It nearly looks AMOLED unless in complete darkness. I would swap your phone ASAP.
Mine does to in a dark room but once it dims the second time when screens off its hardly noticeable. Not what OP has though.
Nothing like that on mine either.
I did notice a very faint glow on the top right of mine but this is as others mentioned...Only barely visible and only in pitch darkness.
What you showed on the top left doesn't seem "normal" at all. +1 on swapping it out. I'd say that's excessive and a defect.

Thanks for the feedback everyone, it turns out that it was not normal. Just rolled back in from the T-Mobile store. Took it in, expecting to be met with some resistance when requesting a replacement. To my surprise, they immediately agreed and replaced it!
The replacement does not have this issue. Glad to get that taken care of, really my only major gripe so far is gone.
Glad to hear it! Happy endings are the best.

Good to hear as well.
So there is no more light bleed on your second screen or it just isn't as pronounced as before?
I have some. The tiniest bit. In a dark room. Totally acceptable. I think this second screen is sexy as all hell
From reviews I knew there was a light leak issue. However, it does annoy me. I wish there was none at all our at least give us the ability to change the brightness. That being said, I initially thought the second screen would be dumb but now I can't imagine being without it. Switching between apps is so much easier now.

Can you try pushing a notification to yourself, while the screen is off and snapping a picture like you did in your first post? I'm curious to see what it looks like because when my screen is off and I get a notification with a white background it's bright on the left corner just like your picture.
I have the same issue on white notifications. Annoying but considering first gen of this type of display...if in future models I'm sure they will have a higher quality one in future.

Went to the T-Mobile store to compare my phone to the display model. After playing with the phones I could see that my second screen display was in fact brighter on the left edge than the display model, so I'll be exchanging mine as well. Hopefully, I get a better one but at the moment I'll have to wait, since they are sold out. It was such a pain in the ass to get the sales associate to see the difference. Unfortunately, she couldn't but when she called someone else over they agreed that it was brighter.
I started a new thread about the dimming of the second screen(probably shouldnt have after reading here). Has anyone figured out how to make the display brighter again with the screen off? I can hardly see it in a lit room..
Thankfully the set I have (HK Dual Sim V10, H961N) has very very slight, almost unnoticeable bleed for the 2nd screen
I exchanged mine yesterday. That top left of BOTH screens was horrible. We went through 5 devices and every single one had some sort of bleed. I picked the one that had the least, and none on the main display. I'm sure LG will revise the HW and fix the issue but anytime you pick up a device with new tech expect some sort of issue.
Mine bleeds a little, but I really don't care.
I have a very light white line across the screen just below the AOD clock.
Now this line is like a smudge and if i rub on the line it vanishes but after sometime it comes back at exactly the same spot.
I dont know how to explain but it seems like dust line and not something that is inside on the screen.
Is anyone else facing this?
May be its oleophobic coating wearing off..
That's crazy
I just got that today as well. Unless I hadn't noticed it before but my phone is 2 weeks old. I have not dropped it at all
I have the exact same thing on my phone, I also noticed it on my wifes phone.
Same here ..
The AOD clock moves, so your description doesn't quite help.
If you use an app like "Display Tester" to show a black screen, do you see the line?

i also have this issue
it like a white haze, a vertical line across the sides of the screen, before it curves to the sides. i have it both sides however left side is longer. it doesn't look like a scratch or burn-in, it's like a vertical haze that won't get removed with any wiping or cleaning.
its not really noticeable in general, only most noticeable when screen is turned off or when it is displaying black or dark images.
Smudge on screen
I am using Smasung S9 Plus and I don't know what is the proper name for it but i am facing same issue.
Temp Solution : It gives you temp solution by using Touch Screen Wipes and Dry Cotton clothes .
but after one or two days it comes again so i am waiting for permanent solution.
