To explain a bit more specific:
There is the pressure test in service menu, common users post that as water proof test workaround i saw.
If I got a black screen and press it gentle to raise the digits a bit around my fingerprint/thumb after releasing there apperas a kind of contures in light colour on that black screen.
Is this a normal behaviour for that type of display?
Not deep into technic of the used display/material i would like to aks. Phone works fine, not using much pressure, just to rase the test millibars 2 or 3 digits maybe gives me these lines around my fingerprint when releasing again in sky blue/white maybe that kind of colour.
Its normal or a hint for something not 100 percent fine?
Thx

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...
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

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?
Here are some photos of Nexus 10 with backcover removed, you can see the screen is fused inside a frame along with digitiser and gorilla glass, the screws you see is for holding the battery and have no effect on the extent of light bleed.
awesome pictures!
Hm.. Have you tried to turn on the tablet with open cover just to see of the light bleed is still there ?
So I wonder...does it just all snap together during the manufacturing process? If the only screws are for the battery then what is holding the screen assembly to the frame? I hope its not the frame itself causing all the problems...that could take Samsung while to fix if at all :/

i guess they are glued together
great photos
have you tried to press at some points to see if the lightbleed changes?
after some speculation i think the backlight on the N10s is set to high
i know that my old Samsung TV looked terrible when using max backlight.
as i dont have any N10 yet (picking it up on friday) im not sure if the brightness slider changes the backlight or the brightness(black level)?
my teory is that the backlight is set at max all the time and you only change the brightness.
thats plain WRONG!
thats why colors looks washed out when increasing the brightness
what you want is also a slider for the backlight
the brightness(black level) should ALLWAYS be the same
if you want a brighter display you should only change the backlight as the backlight doesnt affect colors/black level or gamma.
backlight only increase the white level.
you dont want to change your gamma right?
so hackers and kernel experts
find a way to change the backlight and most of the problems should be gone
i think
also you need to replace or add a slider with backlight setting instead of the brightness slider

I suspect a thin strip of double sided foam tape. Glue aren't typically used on screens as they create fumes which can haze the screen. Atleast not when we install touchscreens for ATM machines. Double sided tapes are easier to apply also. Same process as screen protectors where you have 3 layers with the center being the actual film. In this case center is the double sided tape. Peel one side, put it on the screen then peel off the other side to expose the other sticky side then lay the screen down on the glass. When its not on perfectly is when I suspect light bleed happens.
The huge problem is trying to remove it once its on. You can use heat to try to separate them. With ATM screens they're thicker so somewhat easier to pull them apart as you heat them but with newer phones or tablets they're so thin that if you do this they'll easily crack.
IMO if the light bleed is bugging you just exchange it rather than risk cracking the screen. Then you'll end up completely voiding your warranty exchange

Here's a complete tear down. There's no mention of any sketchiness in the way it's put together or components used.
Today we received and promptly disassembled the Google Nexus 10. In usual fashion we’ll release the take apart video next week, but wanted to go ahead and post the preliminary take apart steps and photos. The model we’ve taken apart is the 16GB Wi-FI model. Model # GT-P8110.
One thing that struck us about this disassembly was the complete ease of taking this tablet apart. Whereas Apple seems to be making it more and more difficult to repair devices by combining parts and using as much glue as possible, Google seems to be taking the complete opposite approach. The end result is a device that is extremely repairable. Go Google!
Another interesting note is how many of the components in the device are manufactured by Samsung. It appears that the battery, processor, and flash memory are all made by Samsung. Is this Google’s way of capitalizing on the drift between Apple and Samsung?
That’s it. The Nexus 10 display and digitizer are fused together, so that is where the take apart ends.
http://www.powerbookmedic.com/wordpress/2012/11/16/google-nexus-10-take-apart-first-look
that cable that says "GT-P8110" is very interesting. Might help with Samsung support reps in trying to identify what the device is
http://www.samsung.com/us/support/owners/product/GT-P8110HAEXAR
Edit: Hmm, just looked at my N10 box and it has the number as well; not sure how I missed that before.

its usually the back light led whose brightness is changed thats y u save battery life when u reduce brightness, what ur talking about is the contrast and thats fixed on the tablet, brightness being led light intensity and contrast being each pixel allowing amount of light through it
ok time to get this tablet perfect
i have some slight lightbleed at the bottom right corner as many has.
if i press at the back of the screen at the right corner i can clearly see that the lightbleed gets worse.
so the conclusion is that is has something to do with uneven pressure at the screen when you can affect it with pressure from the back.
i report back how it went and if i found some solution
A little bit off topic here, in regards to thermal throttling, do you think it would be possible to fit a small blower some where up top where the cpu/gpu is located?
Something like this (16mmx16mmx4.5mm):
http://www.digikey.com/scripts/dkse...ewproducts=0&ptm=0&fid=0&quantity=0&PV46=5197
It would need to be hooked up to 5V, some where like the USB or HDMI port connections on the inside or on the board.
It looks like there is a small hole underneath the camera in the lid that could act as an exhaust, a very restricted one, and the usb/hdmi/3.5mm ports may help intake and exhaust too.
Hi,
My phone fall out on a short distance, maybe 40cm, not even damaging the glass nor the plastic. However, it is now showing pink/purple lines all along, wherever there is black/dark color. Is there any way to fix this without a new display? Already tried to reconnect the display cable but it didn't work.
Some pictures attached.
This may not be a problem in the display, I can think at least 3 scenarios that could generate this error at hardware level:
Short or break in display cable/ connection interface, at the display itself and also in the board.
The only way to know for sure would be to test with another display.
There could be a workaround at software level, but NOT a fix, meaning you could try to make the screen all grey scale for a start, try to mess with advanced display scenarios, maybe there is something in there that can make it look like a little better.

Disconnecting and reconnecting the screen ribbon cable didn't work. I don't really believe that this would be a software related issue. Even the Sammy logo just after turning the phone on, as it is surrounded by black, is shown pink. Everything that is black or dark creates a pink stripe/line from edge to edge, that would move according to scroll or so.
Greyscale won't help either. As it is based on black, almost all the screen is then covered by pink.
Pic from the logo attached.
I received my X F5121 two days ago, and as soon as I turned it on, I could notice a white horizontal spot a bit up from the centre of the display. You can notice it more when on a white blank page and with brightness a bit up.
I also found (more on white pages) that pushing the back cover of the phone would affect the screen with distorted colors and looks like (in my opinion) the glass is not properly installed on the device.
Am I the only one with this problems?
Let me know what you think...
This is from diagnostics.

I know, in facts looking at this image with brightness set at 50%, with my X bent of 160/180 degrees I can see that white spot

Is it like a white patch whether its a white screen, or a light color like beige background, like something is being pushed against a lcd screen, or a light bleed.
I had something like that, not sure if it was when I purchased the phone, but I only noticed it after a few months of using it, I took it a xperia service center and had the whole screen, including the phones outer frame body changed, not sure if the center was too lazy to change just the screen, but im happy with it now.
You should get sony to sort it out, or if you still have a return period for exchange/refund.
