Problem with my EEE pad's screen - Eee Pad Transformer General

Hello, I found this spot on my screen last night. I don't think it dirt or fingerprint because I clean it very well but the spot on the screen is still there. Anyone has experience or has seen this before? any help would be appreciated.

Couldn't you have chosen any worse? I can't even see what you're talking about but I see a little glowing area on the darkest picture.
It could be the light bleeding on the non-edge portions of the screen that some peopl said spontaneously developed after using it for a while. But without better pictures I can't tell. Either the problem isn't big enough or your camera isn't able to focus well enough or you took poor pictures. I think you should take them with a darker background bcause really the left most picture is the only one "I think" I see something in.

I do not see anything wrong as well. Are you sure it's not your imagination?

well I had the background all black and hold my tab horizontally across my eyes. Everywhere else on the screen is black except for that spot. When I surf the web or reading something, that spot make everything look brighter compare to the rest of the screen. I can try to make a video for it tonight.

Looks like light bleed. Mine has that too

Xoom screen dim on the bottom edge

I searched around the forums and did not see anything else posted about this. I just bought the WiFi only Xoom and am very happy with it, except for the fact that the bottom edge of my screen is darker and dimmer.
To clarify a little bit, I mean the edge of the screen thats next to the ports on the bottom of the Xoom. Normally its impossible to notice since I usually hold my xoom in landscape and there is the black bar at the bottom. If I open a pdf file or ebook, and then view it in portrait mode, I notice a darkening of the screen along this edge. It kind of looks like a shadow or a very slight black blur. The darkness is not that exaggerated but once I noticed it, I could not stop looking at it when reading.
Now I normally go on a witch hunt for problems with new devices when I first get them. The more I pay for them, the harder I look. I thought at first I might be doing this with the xoom and kind of blowing this out of proportion, but last night I was showing it off to a friend and he noticed it before I even mentioned it.
Does anyone else notice the darkness along the bottom, or do I just have a defective panel? Its easiest to see if you put your brightness around 80% and then display something that has lots of white, like a pdf or ebook, and then hold it in portrait mode.
I will post pics of it when I get home tonight.
i've noticed on all the xooms i've looked at too, including the one i bought. someone once replied that it was defective, but i think it's actually how it's made.
most people's eyes may not be sensitive enough to notice this i suppose.
I hope this is not the case. This might be a deal breaker for me since I need a device that I can read on a lot.
Can anyone else verify this?
Mines not like that. I'm using the Verizon one. I use it in portrait often.

i just exchanged my defective one (had wake issues) for a new one and guess what - dim bottom too.
that makes 8 xooms i've looked at that have the dim bottom. it's only noticable on white/light bg and if you don't have your menu bar covering it.
i picked up the wifi xoom yesterday and noticed it when togglieing the bottom right corner setting button (battery indicator). When looking at this the entire right portion of the screen dims. Other than that, it is not noticeable.

This is a purposeful UI effect (what you are talking about, not the OP).
For the OP, I looked at my Xoom diff brightness levels, angles, orientations, etc, cannot see any dimming. 3G model. Not very helpful, I know.
also, if you look at the top of the screen (landscape mode) at an angle you can see the light source. the lighting just isn't even. i'm positive that if i look at anyone's xoom i'll see it since the back lighting is made the same on all... unless they switched mfg's in production like the evo4g's did.
Well thats a real bummer. I think I might just hold onto mine for a while and maybe try and do a warranty replacement later in the year if they fix this issue.
Did you notice any 3g models having the dim bottom, madsquabbles? Or for that matter, has anyone noticed this on the 3g model?
I first noticed it on the 3G. thats when I posted my first question.

Display problem/yellowish left side

Just got my new SGS2 3 days ago, really liking it but stumbled into a screen problem and would like to know if it's just me/it's normal/I need to change a setting to fix the problem.
Just like the title says, the left side (about 1/3) of my screen changes the colour of the image to a more yellowish tint. This seems to happen just when the brightness is quite low, and tends to disappear when close to 100%.
It is rather subtle, but can be seen where there's white text on a darker background (white characters become darker the closer they are to the left border), or when looking at an uniform colour.
I created this test page to make the problem more apparent: http://fiddle.jshell.net/qFxsC/1/show/
When visiting it on the S2 browser and setting browser brightness to around 20%, it becomes quite visible.
Anybody else with the same problem?
EDIT:
We still DO NOT have pictures of a phone WITHOUT the problem described above!
If you believe your SGS2 has a perfect screen, please post pics of the notification area taken in the dark at both 0-20% brightness and 100% brightness!
UPDATE
Various websites have started to talk about this problem, linking to this thread:
- http://mobile.engadget.com/2011/05/30/is-your-galaxy-s-iis-display-yellow-on-the-left/

I have just sent an email to GSMarena asking if they could check the unit they reviewed to see if it has the same problem. Of all the phone reviews I have seen, theirs seems to be the most focused on image quality, I'm sure that if their unit doesn't have this problem, they would be able to take clear shots of a flawless screen.
EDIT:
GSMarena took screens of their unit using the above test link, and while so far I believe theirs is the best looking display that we have seen so far, it *STILL* has the problem.
I am going to link this thread to samsung UK next, in the hopes they will give an official answer acknowledging the problem.
EDIT:
latest firmwares seem to fix this problem or at least make it much less noticeable.
Take it straight back and swap it. Seems to be a growing amount of people on here, including myself, with various dodgy screen issues.
B
The screen doesn't look perfect if you look at a uniform color on the whole screen + low brightness, but... well I don't tend to use it much for that. Could be a limitation in OLED production-technology getting all the pixels to have exactly the same brightness/color etc.
edit:
To answer directly to the question here, no I don't have a yellowish left side. It's just not completely uniform across the whole screen.
I've got this same thing. I first noticed it when using Estrongs file explorer. I always have my screen turned down to 0% to save battery, but didn't notice this anywhere else yet (at least I didn't think about it).
Your posted image does show it clear.
What to do? Could you others comment whether you've seen this? Go to the OP's posted link and set your brightness down to 0%.

I tried to mess around with settings such as auto adjust screen power etc, but the only thing that seems to fix it is crank up the brightness.
We obviously can't keep it anywhere close to 100% tho, this phone sucks battery down quickly already at 0%!
Another thing you can do to check if you have this screen problem is call *#*#0*#*#*
This will make the phone go in the diagnostic program, and if you try the white diagnostic, you can somewhat see the problem, although not quite as clearly as in the test web page I posted above.
I'm considering to return the phone, as it doesn't seem to be getting better, despite having read that some screen problems might go away after a few days.
Mine is exactly the same. It's noticeable at the lowest brightness setting, however if I increase the brightness even slightly it pretty much disappears for general use. It's still there but not really enough to bother me.
On the OP's link I changed the brightness through several settings and at certain brightness levels the whole screen gets a yellow tint. Not necessarily related to the left side of the screen having a yellow tint, apart from I guess a lack of brightness of the blue subpixels relative to the red and green.
I'm not sure if I'm imagining it but I think it has improved slightly on mine over the past week. However if it gets any worse I think a warranty claim will be in order.
Hhrrmm, I'm in a catch-22 here. There's generally a grace period for any manufacturing errors like this where you can quickly get a replacement just by returning it to the vendor. Problem is, my vendor won't be getting any new units in for another two weeks.

I don't see it clearly on the link he posted.
But i do see it in the notification screen. The grey area is slightly darker/yellow tint on the left site. Even when i put it on maximum brightness you could see it. Especially when you first concentrate your eyes on the right side for 5 seconds and than on the left side.
I do seem to notice it on the notification grey slider where your finger is on when you pull it down, on the left side the grey is a little bit "darker" than on the right side of mt finger.
I tend to think I can also see it on the keyboard, whereas the Q has different grey than P on the opposite of the screen...
Anybody could check this out on their phone??
Thanks in advance!
As time goes by, it feels like my problem is getting worse, although it may only be due to me being aware of it.
Also began noticing it in the pull-down message field. Now I see it against white backgrounds as well, almost like a faint green-grey shadow.
I've contacted my vendor and requested an RMA and replacement. They're sending me a shipping slip to send it to them "for control" then they'll contact me on my options from there. Can only hope they see it as clearly as I do and that they send me a new phone as a replacement rather than repair/refurb crap.
Think this is the last time I buy electronics online. I saved 20% off retail on this one, but having the option to do a walk-in replacement at a brick-n-mortar store would have been worth the higher price. <sigh>
I've got the same thing aswell, a slightly yellow/brown-tinted shade towards the left side of the display. Also visible for example in the market menues, the white areas seem to be very slightly darker towards the left side.
Not sure I am bothered about it enough to return it, doesn't bother me unless I specifically look for it. Also it really is very slight.

If everybody has it, no problem for me.
But if the majority does not have it, I would like to have one without it. Do you think Samsung knows abouth it?
When you have a full grey pictuere or just the notification screen and you go into a perfect dark room. Can you also see, some white vertical en horizontal lines? Looks like hardware where the screen is build on?
Here is a photo I took of my screen with a grey background (see below - click on it to enlarge).
For me, its visibility seems to vary depending on the ambient light, but I'm definitely seeing more effects of it now.
Really hope I'm able to get a good replacement. Am reading quite a bit about this, banding, lines and dead/lit pixels.
so do you think it's a hardware issue, or maybe it will be gone??

The lines you mention are present both on my SGS and my SGS2. It seems to be patterns in the actual OLED pixels, and the patterns and lines are static even when you move pictures. Mostly visible on lower display brightness settings. I've gotten used to them and they don't bother me, and since I have the same thing on two SAMOLED-phones I'd chalk that one up to "just the way it is" aswell. Using anything over 50% brightness has them mostly fade into the display light so only really visible on the lowest brightness settings.

This what you mean?
My Samsung focus and Cowon s9 (which I don't even think has a samsung oled screen) have that as well on the lowest brightness, I think its inherent to the tech.

Ah ok thank you!
On a grey pick with full birghtness I can see them too.
On the post 2 post above yours(quist his post) you can see the lines, but now they are not white, but darker, can you confirm you see them and this is what you mean?
Do you also have the yellowish tint on the left side?

For both the SGS and SGS2, the dark lines are there for my devices aswell. They can seem a bit "grainy", and don't seem like perfectly defined lines, though they generally are always straight horizontal or vertical lines. I also have the Xperia Arc at hand, and if you look at a grey-ish image on either the SGS/SGS2, or the Xperia Arc (LCD), the Arc generally has a very smooth grey image, while the SGS/SGS2 has almost like a fine overlay of subtle lines or grids, generally darker in color than the image displayed, though not clearly defined and not completely symmetrical across the display.
Doesn't seem symmetrical enough to be a grid fo the digitizer layer or smtn like that, but definitely a pattern in the display itself. I still pick an AMOLED screen anytime of the day, the Arc display, while more uniform and "blemish"-free in this regard, still has that LCD backlight bleed-through which for me makes the display alot more tiring for the eyes.
Also my SGS2 has a very subtle tint towards yellow when viewing some of the grey test-images some people have posted. Never noticed it on my SGS1, so either I didn't look well enough, or it might be either hardware-related (something causing the pixels on the left side to perhaps not get the same amount of control voltage/whatever for the pixels, thus causing less blue/more yellowish color), or software. Either way, it is way too subtle for me to care at all, maybe this is even according to spec for the SAMOLED+ and some use will even the pixels out, not sure if anyone has some inside knowledge about the SAMOLED screens.
I am definitely seeing this problem getting worse, now it is getting rather obvious as long as phone is lit by artificial light or in the dark, while sunlight seems to make it really hard to spot, even if not direct.
I've been given advice from samsung call center to bring to phone to the closest assistance point, which I'm going to do tomorrow - hope to be able to report back that it is a known problem and they will change my unit.
I hate to make an iPhone reference here, since I'm *not* a fanboy, but Engadget reported when the IP4 was released that yellow spots and banding were due to glues that had not completely dissolved/disappeared and were part of the bonding process of the screen:
http://www.engadget.com/2010/06/24/iphone-4s-yellow-spot-issue-goes-away-with-a-bit-of-time/
Now - the picture above showing a completely yellow left-side display - that looks 100% abnormal and I'd RUN back to the store to swap it out. I don't think that's glue related.
Download an app from the Market called "Dead Pixel Test" and run it with the white setting to see what it looks like. Is it still yellow?
Have this same issue. Noticed it right away unfortunately. It will always bother me if I deal with it.

I do not believe a Note with a good screen exists

Please prove me wrong!
Anyone have any links to videos showing a Note rendering dark grays correctly?
watch the demovideo on your note.
The dozens of reviews which acknowledge how good the screen is proves you wrong.
Pfffff. Tests with Samsung handselected devices. Or do you think that Samsung will send defectiv devices to the testers?

Mine is fine with some tweaks. Primarily -40% contrast. I can see down to '2' on that test image. I also notice little or no blotchiness in dark videos any more, although I did before adjustment.
It's a software issue IMO.

I share the same sentiment as no one with a 'perfect screen' has shared it. The best I've seen is one w/o any black clipping what so ever since his gamma test result is similar to a Galaxy S2 but I do see a few visible horizontal lines on a grey screen. Its not perfect but its with in specifications aside from the lines.

To the unwise it may seem incorrect since they are only looking at the smaller picture and dont really have a clue on what this 'objective' test is for, let me give a real life example:
Using the Kindle application for reading ebooks gives you the option to use a black background now some screens have very visible blotches even if there is a text on the screen and they are become unoticeable when there is a text above them, this of course matters to someone who reads ebooks in their bedrooms w/o any external light source or to someone who watches movies like me. You see if we ask someone to open kindle and load up something and do this and do that, it makes the 'testing' more subjective rather than just test it in a pitch black room with a black image displayed.
These tests may sound silly to others but its the best way to get an objective result, remember people theres a difference between 'its not there' and 'i dont notice it with normal usage'.
here is an example that hopefully may enlighten you people with self proclaimed perfect screens so you may understand why its so difficult for others to accept such screen exists because with several replacements they havent seen one yet and people always claim that defects are the extreme minority, if its true then no one should need more than 2 replacements to get these perfect screens, correct?
It is also common for others to be dismissive of any screen related issues, you can be dismissive all you want provided you show an objective result. till then your screen is just as flawed as everyone else.

Are those dark rings one of the issues that everyone is complaining about? If so, I'll have to look at my unit, but I suppose I've just been extremely lucky. I have yet to notice any issues. That's not to say there aren't any issues with my device (possibly), if I look really hard, in very specific conditions
I do not have any black blotches or whatever.
One of the issue I have is the gray screen. It has somesort of texture on it but it's tolerable since it looks like a texturized wallpaper. No problems with playing videos at all, everything looks crisp and clear. So far I am enjoying it.
Also, another issue is the camera. When I am around those long florescent lights, there seems to be some wavy things on my screen. Even on video. I guess I got to avoid those lights in taking pictures. Haha.

That Image i used came from the Tab7.7 forums which shows the issue and practical scenario at the same time. Its an example of the darker blotches in blacks, not really the main issue on the Galaxy Note but one of the many possible yet rare issue.
On my end, my first screen had some blotches but they were not visible when I watch a movie or read an ebook from the kindle app, the 2nd screen I had did have a home button sized like blotch at the bottom which was visible when reading ebooks unless a text is close to it, in movies/shows it is only visible when the entire screen goes black.

Once again, I guess I have been extremely lucky with both my Note and my 7.7, because I have yet to notice any of these issues with either
Black clipping and banding = software. Therefore, irrelevant from a hardware perspective.
The splotches that you see in the most dark of conditions are the artifacts of the manufacturing process. Under normal 0% brightness (without using additional apps like screen adjuster) you will not be able to see these things assuming you've got a good screen.
The only things you need to look out for is color unevenness and brightness unevenness and in some cases, the manufacturing process is so prominent that it seeps into the normal brightness (0% and up range) and it is visible.
The fastest way to tell if there is something wrong is to turn off all auto-lcd power management, set the brightness to 0%, and to simply pull down the notification menu and view it in a dark place. That'll reveal most of the problems that you might find in a day to day situation. If you see nothing there and the screen looks crisp, don't bother looking for more. They will not appear in normal real-world situations.
No blotches on mine. Very happy with the quality. The color profile seems nicer than on my i9100. The only screen I had with noticeable blotches (only seen at full darkness) was on my T989.
So ya, very happy with my Note's screen. White International N7000
The witch hunt started with the original sgs and continues with the note.
Im on my second note plus a screen replacement and screens are flawless. Yes there is somme banding on all of amoled screens. Its partially software because running ics alpha build, most of the banding is gone.

Who makes the screens

Hi,
I'm just wondering who makes the screens for the Nexus 7. Is it one manufacturer, or more than one? I bought a 32GB N7 a few weeks ago. Except for a little bit of screen lift on the right side, it's been fine. It's not enough for me to return it. But I also noticed that the screen was a bit yellow, with more yellow on the right side than the left.
Anyway, my wife really likes my N7 and her birthday is coming up, so I bought her one from the playstore. I took it out to set it up for her, and noticed that the screen is completely different. This screen is not at all yellow, and seems to be much more even than mine. But I've noticed that when light reflects off of it just right, I can actually see the web of sensors right below the glass. It's obviously most noticeable when it is off, but it can also be seen when it is on. It pretty much requires a light to be shining directly on it. On mine, if I look really carefully, I can see rows of little dots, but no web (not sure that web is the right word. Looks like a web). When off, if I reflect light off it indirectly, the LCD reflects back blue. On mine, it reflects back more greenish.
They both look exactly the same when viewing images. I can tell no difference at all. But like I said, when viewing white, mine is more yellow and uneven.
Anyway, just wondering if there are multiple manufacturers, and if not, what could account for the pretty big differences? As an iPad owner since the first one, I am used to multiple screen manufacturers.
Call the manufacturer ASAP mine had screen lift and i didnt notice until my screen randomly broke one day and the crack was right were the screen lift is. now the lower right portion of the touchscreen doesnt work and im using and external keyboard and touchpad. to answer ur question though i have no clue who makes them.

Nexus 4 annoying visible IPS sensors

Hey guys,
I've had my nexus 4 for a week now and I am super pleased by it. The phone runs like a dream.
The only issue I seem to be having is that I can see the IPS sensors even with the screen on!.
I'm talking about the little transparent-gray squares all over it, not about the super awesome dots that you can see with direct sunlight.
This is flipping me out!
Is anybody else having this problem with it?
I can't appreciate the beautiful screen because of this.
Also, when displaying single color frames specially dark ones, like on the clock app , the colors are not really solid.
I get this vertical stripes that are approximate to the color but not quite it.
Im posting a screenshot but I don't think that youll be able to notice it since it may be a hardware problem.
Sent from my Nexus 4 using xda app-developers app
That's a hardware thing, not visible in screenshots. You'd need to take an actual picture.
Are you referring to the dot grid that is visible in direct sunlight? Everyone has is. It's because of the fact that the screen is integrated into the glass.
I think it looks kind of cool but that might just be me.
Edit: Gotta read the whole thread first I guess you're not talking about the dots. I have no idea what you're talking about then.

Question to the OP. Do YOU see anything wrong with those images, or is it a hardware problem? I can't see any difference between your screen shots and my phone.
Damn it man, now i see them too -.-
I went to the clock app, and i can see some stripes on the left but mine are vertical.

That's a hardware thing, not visible in screenshots. You'd need to take an actual picture.
Are you referring to the dot grid that is visible in direct sunlight? Everyone has is. It's because of the fact that the screen is integrated into the glass.
I think it looks kind of cool but that might just be me.
Edit: Gotta read the whole thread first I guess you're not talking about the dots. I have no idea what you're talking about then.

Haha Dude that's the digitizer. Don't worry. It's all cool.
Chill out people.. Its just the digitizer that you can see, so close to the screen for better touchscreen responsiveness. The most likely reason you can still see it with your device screen on is that you have your brightness too low.. Put it up
even amoled screen are also the same

When I first got my Nexus4 the weird screen was the first thing that popped out at me. Between the visible digitizer matrix that glints when it catches the sun wrong, to the odd rectangles that can be seen behind the screen I was initially bummed and thought about returning the phone. It doesn't even bother me anymore
This is my 8th android device and the first one that has a funky screen like this, but it really isnt a big deal. Under 95 percent of conditions it looks really nice
I have been able to see the digitizer on every single capacitive screen i have ever owned.
@David_Azar I have to agree.. initially I was disgusted by how prominent the digitzer pattern was, I've never had ANY screen show it as much as the Nexus 4 does.
However, the vertical stripes you're referencing is commonly referred to as "banding". I have this on my Nexus 4 as well, most visible on grays (especially darker grays).
I have been doing some research and I believe the banding issue will reduce over time. If you check your screen when displaying a white background at max brightness, such as gmail or chrome browser, you should see a slight yellowing of the whites. It appears this can be due to the adhesive they used to glue the digitizer to the screen not curing completely. After several weeks of use, the heat from the processor will help cure the adhesive causing the yellow to disappear after a while.
I cannot say for certain that it will completely resolve the banding issue, but I have noticed that the worst banding is in the areas where the yellow tint is most prominent. I have also been testing my display every day to monitor any changes, and I am happy to report I do see a minor reduction in both the yellowing and banding (I've only had my Nexus 4 for five days so far).
Give it a couple of weeks, run some intensive games to get the processor to heat up every day. Keep brightness at max for the next few weeks and let us know if you see any improvements.
As for the pattern of the digitizer in the glass.. it's not going anywhere so get used to it. I don't like it much either but it seems to be less prominent once you start becoming used to it.
Good luck, let us know how it goes
Hey man,
Curiously enough I've never had the yellow tints everybody's complaining about. I'm used to The digitizer matrix ( rectangles) buy at first it was really weird. I was coming from a non HD display ( a RAZR Maxx) so naturally, I expected that my N4 would have a perfect screen.
I've had my N4 for almost two months now and the banding has not reduced. I made some research over the last month and I found that with some kernel settings for saturation the banding is reduced. I'm not sure if it is really reduced or the clear gray tones that have the banding just don't appear anymore because of the saturation.
The Trinity kernel reduces this a bit but like I said, your screen will look life a f*** ing AMOLED.
Right now I'm using the kernel provided by the 123 FAUX CLOCK project. I'm using the LG factory presets and for the most part I'm really happy with the screen. If you or anybody else comes up with a different solution, let others know on this thread.
Peace brothers.

Just for kicks, if you stop by a T-mobile location compare your screen with the display model and see if you can spot the yellow tint on either screen (on a white background)
I will update this thread with my phone's progress (or lack thereof if it stops improving).
I get banding issues also, more noticeable in grey backgrounds; but I can I see them in other colors if I look hard enough
I use a dark black theme to avoid looking at those bands
I can say this. I've had a ton of devices..latest was s3 and I'll just say I'm stoked to have IPS over pen tile. Just knowing HD was plagued by this alone was enough for me to ditch Sammy all together especially after seeing rgb on note 2 was no better. This is my opinion of Samsung's design ...I know why they chose it but I can't and won't buy another amoled until they get another tech in order. So now I say kudos on IPS but I'm surely a screen purest and I found these hardware screen/digitizer artifacts you speak of and to me its so much less noticeable. Your not alone. You just like good clean HD like me. Lol HTC one should be a nice one to check out...

That would be a little like kicking myself in the nuts. Nothing good can come out of that.
If I spot the yellow tints once, then I will always look for it. I hate doing that with the banding but it's an automatic thing.
I dunno why but it really bums me out whenever I have a problem with my phone.
Let's keep posting of someone finds a solution or something .

I've got the quite visible digitizer rectangles too. In anything less than a dark room if the phone is not on a perfect angle they are visible.
I can't really tell if "everyone's" is like that, or just some are "worse" than others.

Here's an image with them visible with the screen on (and at an angle) - difficult to take a photo of - but much easier to see with the naked eye.

Few more with the screen off.

Went and checked out an Optimus G today (Nexus 4 isn't actually released in Japan). Given that a Nexus 4 is just a remodeled Optimus G I thought it'd be worth comparing screens. The digitizer matrix is barely visible on the G I was looking at with the screen OFF. With it on you could almost see it at some angles. It is much more visible on my Nexus 4 which you can almost always see with the screen off and at an angle and often with the screen on.
I'm leaning towards my phone being "less than a perfect example of a Nexus 4" and not the "norm" at the moment.
they are much more noticeable in Rev 11 devices and they where barely visible in Rev 10, i am sure that there is a technical reason behind it

See that explains it a little more. Not sure I see the logic in putting a screen with pretty decent viewing angles on a device and then sticking a really visible digitizer on it though.
I've contacted the seller and I guess I'll wait and see what they say in regard to it.
