NotePro 12.2 inhomogeneity / yellow discolorations - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

Got my 12.2 today and was a bit disappointed because of yellowish discolorations in the top corners.
What can you tell about your own 12.2 about that lack ?

Did you check on white / grey background ? Still all fine ?
Found out the yellow´s intensity increases significantly in horizontal view.
Hopefully the exchange unit will be better ...

just got a hold of 8.4 unit and it has a very warm, "yellow" screen. especially, when compared to my LG G2 and hand picked iPad 3 (which was picked out of like 10 units with yellow discoloration). i hope not all of them are on the warm side like that and it's a typical screen lottery like with any tablet these days (which is extremely annoying). getting a replacement.

Screen light blee.

Hi guys,
Do you have any light bleed on your screen? I have a few spots on the bottom edge of the screen.
Thank you,
Martin

Yea, That's Samsung for you. I was lucky not to have any on my device. And from the looks of it, it isn't too common on the Note 2014.
The Nexus 10 though. Wow. Everyone had it. It wasn't a question of if you have it or not, it was about how bad. Not to mention the blacks were blue.
I'd exchange it if I were you, no point in getting stuck with that.
Nope, no blee here.

I will exchange mine. Hopefully the new one will have no bleeD
Mine just came today and with my normal brightness setting there is only the slightest hint of bleed from one of the four LED spots on the bottom of the screen.
My panel seems perfect so far so it doesn't seem likely I will exchange it over this.
I'm pretty impressed, but I have to say the build quality is not up to par with my IPad and not what I would expect at this price. Samsung has a long way to go to produce really premium products.

I would like to see one iPad without a light bleed. So far a few I saw (including 2 which belong to my wife) had some light bleed as well. What is wrong with build quality of your unit? Mine, except for light bleed, is very good.
I think my tablet has very very slight bleed at the bottom of the screen near both capacitive buttons, I won't return it because it's barely noticeable BUT does this mean the whole screen has an issue and also could it deteriorate over more usage or anything like that.
Apologies if these are idiotic questions but this "screen bleed" is a completely new subject for me lol.

How was your exchanged tablet?
I think my light bleed is actually getting worse and I am thinking about exchanging it now that there is more stock available.
One of the spots on the bottom is about 1 cm, and while viewing movies it is a nuisance.
Does anyone have a perfect screen?

This was my worry, my screen has slight light bleed at the bottom nothing too noticeable but then again don't all LCD screens have some form of light bleed
Writting from my third Note 10.1 2014. The first one had a huge dust particle under the screen and bad bleeding. The second one had a bearable bleeding but at least 7 bad pixels (3 dead ones right in the middle of the screen and 4 stuck). This Note 10.1 has almost non- existent bleeding and just one little dust particle (invisible if you are not looking for it) but has yellow tint along the bottom edge (over the buttons) and at the bottom left corner, so when you are reading in portrait mode over white background it is impossible not to get distracted as you start one line with black over white and you finish it with black over yellow.
I truly love this device but I am getting tired of all of this. My third replacement is on its way, though I seriously doubt it is going to be a good one.
iiSo say we all!! from my SM- P600
Just noticed the blee today while watching netflix...does it actually get worse? I can live with it now but I would send it in for a replacement if it's gonna deteriorate over time
I'm on my third device and 2 of them have had lightbleed. I can't say for the first one though because the screen was dead on arrival. I think everyone should expect some lightbleed on any LCD screen. If your tablet is perfect in every other aspect other than a little screen bleeding then I wouldn't exchange it. There are too many things that can be messed up other than the screen such as S-pen detection, loose speaker grills, dead pixels, dead screens, faulty bluetooth, and the list goes on...
I have a 32bg black model and my GF has a white one, both bought at BB at about the same time. There is quite a lot of difference between the screens, mine has quite a bit of light bleed on the upper right and all across the bottom - you can see the individual leds - hers does not. However my screen is quite a bit brighter and much more "white," in side by side comparison hers looks a bit yellow. All of the screen settings are exactly the same. Last night we had them both on for 3+ hours of internet and point-and-click gaming, I had 80% power remaining while she had 56%, checking hers I noticed the brightness was at 100 while mine was around 25%. She says it needs to be that high to see the game and it does seem much darker/mudier than mine. Thinking these must have different panels because they look so different. So, light bleed or dim yellow battery eating screen, are these our options?
The pictures were taken with an iPhone 5S (flash off). The tablet's brightness was maxed and as you can see, the room was dark. Does this degree of backlight bleed warrant a return (mainly concerned of the tablet's longevity. Thoughts appreciated.

here it is. Same exact conditions. Thanks for your opinion, in advance.
The picture isnt very clear as its difficult to take a picture of properly but if the points I have highlighted are the only bit of screen light bleed you have then yeah its normal, I have pretty much identical bleed points too as do most people on here.

Thanks, I appreciate the prompt response.
And I'm inclined to agree with your observation. In particular, those are indeed the points of bleeding.
What do you make of the top corners being so bright, though? It's not like the points you've highlighted, but rather large areas -maybe this is where the light comes from?
In all honesty, I'm more concerned about future degradation than anything else. If the device is going to remain as is, I don't mind the current state of bleeding. But if this is an indication that the device will be noticeably worse in a few months down the road, then I'd like to take it back to the shop and exchange it.
Again, thanks for your time and opinion.
Much appreciated -and thanked.

No problem mate.
From what I understand Lightbleed comes from the points it's visable - it's just that for whatever reason the device doesn't block the light passing through hence the brighter areas along the bottom. And about degradation from what I have read it doesn't get worse or better just stays like that.
It depends on you if you want to give it back and keep trying to get a bleedless device but as some form of Lightbleed is common on LCD's it will be tough. I returned one due to high Lightbleed which was visable in a lit room and the brightness on low - that's bad Lightbleed and I couldn't accept that so I got the one I have now and the Lightbleed for me is more than acceptable. Plus the other problem is if your device is perfect apart from the bit of Lightbleed your next one could have other issues LOL.

Huge backlight bleeding tab 10.1

I purchased the tab pro 10.1 yesterday. Th screen is fantastic but when I tried to watch a movie with dark scenes there was a very noticeable glare like a white cloud everywhere on the screen that moved when I moved the tablet. I ran a backlight bleed app and when the britghness is 100% this effect is much more pronounced. Nothing like that on my Lg gpad 8.3 or my Samsung galaxy tab 7.7. Anyone notice anything like this? This can't be normal right?

Unfortunately all the new tabs from the Note 10.1 2014 and up have horrible light bleed. I'm on #4 Note 10.1 2014 and I gave up and kept it since it's only seen in a dark room with a black background. Some are worse than others but I got 4 in a row that had 6 to 7 light bleeds at the bottom in landscape mode. Most tablets have some even Apple. It's bad quality control because I just bought a Dell Venue 11 Pro and it has NO light bleed and when you see black, it's like the screen is off and not with a glow like all these Samsungs. I even had to return a Samsung 55" LED TV in December.
Good luck.

I exchanged it for a new one at the store I bought it from, but unfortunately it has the same problem. And keep in mind that I live in Greece so I paid a premium price (579 euros) for this "premium" tablet. And now I am stuck with it!

I know it's the worst light bleed out of all the tablets I have from the following:
Acer A500 10.1"
HTC Evo 4G View 7"
Nexus 7" 2012
Galaxy Tab 3 10.1"
Galaxy Note 8"
Dell Venue 11 Pro
It's something with these High Resolution Displays. I was going to buy the Galaxy Tab Pro 8.4 but people are complaining about the light bleed.
It's unacceptable and Samsung in knowingly selling them.
I'm not sure I'd call what I'm experiencing on my 8.4 light bleed. The bottom left corner is just slightly darker. Not noticeable in dark(er) screens, but noticeable on lighter apps like Gmail. Will be taking it back to Best Buy for exchange. Kind of annoying to have to set it back up again with all my preferences.

I bought a Galaxy Tab Pro 10.1 too. I had an Asus 10.1 tablet prior with no light bleed issues. This one I see 4 light bleed spots on the bottom. My research has led me to believe this is common, sadly. I also see a blue hue when the screen at the bottom is white. But it seems to be different that the light bleed. Neither are horrific that I need to replace it. But it seems if I wanted to, I'd be in the same situation. However I wonder if the back can be popped off as I've seen for the battery replacement, can the lcd be tightened down and fix the bleed through?

Screen tint

The screen on my 8.4in Tab S is bugging me, is it just me?
With all "super enhanced" colour settings set to plain and boring colour, I keep noticing a slight green tint in the central area of screen when viewed square-on, it's very subtle and seems more obvious with text on the screen, e.g. the Tapatalk forum listings. Also when viewed from an angle the display takes on a slight blue tint, despite reviews saying how good the angles are, it seems worse than the LG G Pad.
Is this just a feature of AMOLED displays or could it be a faulty unit (how?)?
I don't see it. Sorry.

There shouldn't be any differences viewed at any angle with this screen. Try this... in bright sunlight, with the screen off, look at the screen on an angle. It should look a uniform color - actually almost exactly matching the titanium bronze bezel... just to make sure there is no physical defect.
Something to note - if the screen is OK, it could be your eyes (not joking). The eyes can play many tricks - for example, seeing a lightly shaded box with text on a piece of paper that is only black and white - the box can appear to be shaded slightly red. That's one example, but there are many. And with the resolution and technology of this screen, there are no imperfections to draw your attention, like staircasing, blur, backlight irregularities, that you are used to seeing. It is a bit confusing to our physiology, and our brain does this thing called "patternization" that can contribute to us truly seeing something other than it is. This seems to be more subtle, yet more frustrating on a display that is so close to perfect.
I'm not saying that there is something with your eyes specifically. It could certainly be a defective screen. One way to find out would be to take a look at someone else's - also, if you have another decent camera, you can take a picture of the screen and look at the picture - that will usually confirm (or not) whether what you are seeing is there. Like I said, it's not you or your eyes I'm dissing. These are things I've picked up on over the years. In fact, it could ONLY be my eyes. If that's the case, I'd probably rather not know.
You can also use a colorimeter and software like HFCR to get the discreet measurements from different parts of the screen. When I have done this, I've found that there was no real difference in chromacity. Of course, that has always made me walk away thinking that the colorimeter must not be accurate. So human.
I would definitely be interested in your feedback about what you find because I've obsessed over high resolution displays trying to figure out what is real and what I'm imagining... it's an active area of interest for me.

Yes I have also noticed this. I've seen these green or pink tints on all the amoled devices I've owned. You need pretty good eyesight to be able to notice it. You shouldn't be bothered by it, they're all like that, if you can see it. But you'll get used to it.
I probably will not get used to it...

Thanks Freshman206 and SrAdama, glad (?) to hear that it's not just me, I've had the tablet just over a week and still notice it. Any slight tilt and the colours appear/shift, green, pink and when angled beyond what I'd consider normal, blue.
Have photographed it and will have another go at getting it clearer but by winding up saturation the effect becomes visible in the photos (on pc).
I'm now trying to decide what to do about it, I have an LG G Pad which doesn't annoy in this way, though it has just gone away for a warranty screen repair for bright spots (not stuck pixels)!

It is probably the antiglare coating you are seeing.. If you have the coating on your glasses and check them out, it will do the same thing as your tablet... I also noticed it appears to have a anti fingerprint coating on as well, very nice indeed :>
In shops I also have compared 3 different Tab S.
All had an immediately visible green tint, white looks not white but greenish and a bit "washed out".
I find it a bit surprising that with other devices, when they have a tint (like the yellow tint of the Xperia Tablet Z), people complain much, while here, with this really apparent tint, people tend to say: It's normal, get used to it...
I would never buy a Tab S, just because of this tint and because of the, compared to other devices, low maximal brightness.
These devices are overrated.
I ran a poll in this forum as to whether people were satisfied with white reproduction on their tablets or not. Out of 15 responses 12 were satisfied.
We have heard reports of manufacturing defects such as yellows screens, muddy splotches in the middle of screens, loose creeky backs, warped backs and excessive lag/stutter.
These are not "normal" for this tablet but represent what may be a bad run of tablets that made it out of the barn. If you are experiencing the issues suffered by the OP, I suggest you seek a replacement unit. If you have observed similar performance from other tabs in the same store that would make sense as they are likely from the same faulty production run.
When operating normally, white should be white on the Tab S. For myself and the large majority in the poll, this is the case. I have also not read any reviews by professionals mentioning this discoloration and believe me, if CNET or THEVERGE had something to rag on the Tab S about they would have.

The average rating by actual owners of the Tab S 10.5 white at BestBuy is 4.9 out of 5 stars with 36 reviews.
You will see very little if any mention of an issue with yellow or green discoloration. I'm sure you are seeing what you are seeing but the problem does not appear widespread.

I just took a picture of a webpage with a white background on my 10.5 and sent it to my laptop which has software that measures colors.
The website background from my Tab S 10.5 measured at 255:255:255. That is pure white. This was a photo and not merely a screen shot.
Saw the 10.5 inch and 8.4 inch models together on display in a shop. The 8.4 inch version also had slightly yellow tinted whites when looked at directly, not as bad as I was expecting though. The 10.5 inch model had no yellow tinted whites at all, when looked at directly or tilted.
Mine has pinkish tint at the top visible when everything is white especialy when reading wikipedia

Yes the Basic profile is meant to be that way its not the screen problem being discussed here, if you wanted an accurate image then Basic is the closest of all the profiles. If Basic looks washed out to you then your used to looking at an oversaturate screen, if you were used to looking at calibrated screens then all three profiles would look over saturated.
I had the 8.4 and just returned it. I also had the greenish-blue tint when the screen was even just slightly tilted. More noticeable indoors with brightness set to below 40%. If I had the tablet flat on the table and walked across the room, I could see it too - screen only looked good if looking at it directly in front of you. As others have said, I think it's probably due to some coating on the screen, which explains why it would be more noticeable with the screen brightness set lower.
I've checked out a few display models at stores, they all basically look the same, though some were slightly worse than others. That being said, the 10.5" ones I saw don't seem to have this problem... if they do, it's definitely not as noticeable. Not sure if it's just an optical illusion or what, but the 10.5's look OK. I'm going to go buy the 10.5 one today, mainly for the size. I'll post again if there are any tints on the screen.

The problem was a green tint in the center when looked at head on not at an angle, seeing shifts in color when tilted is normal for this tablet. I would have kept yours if it was fine straight on.
My 10.5 had greenish yellow tint when looked at head on exactly the same as the op.

I was gonna return for the 10.5" anyways, the screen tint wasn't part of that decision, but I certainly won't miss it, heh.
Mine it is extremelly yellow! I hate this bug... It happends to me every 10 minutes, i need to restart every time to revert this.

[Q] Pink tint on lower half of screen? Normal?

Hey everyone,
I got my black AT&T Note 4 earlier today. I noticed the lower half of the screen is slightly darker, and has a slight pinkish tint on a white screen.
I do notice it in some apps, like Kindle when readinga book. Top of screen is slightly brighter, and when background is white there's a very slight pink tint.
Is that normal? Or should brightness be uniform and no tint?
EDIT: I added a photo. It's not a good photo but you can see how one side is tinted differently. In the photo the brighter top looks greenish but in real life it's not green. You can also the slight pinkish tint in the bottom half, which is the left side of the photo.
I wouldn't want to comment based on the image you uploaded directly since how a camera captures a digital display is much different than what the naked eye will see. If the picture on the panel is not consistent and appears polarized in any way, I would consider that to be faulty. Get it replaced.
Galaxy Note 4 (pink tint lower screen)
Hi there,
I have also noticed a pink tint on the lower half of the screen on new Samsung Galaxy Note 4.
As i intend to do a lot of drawing on this device the tint is unacceptable.
I wonder if there is a way to calibrate the display?
I had this issue with my Galaxy S3 display. I had at&t exchange it.
Have this same issue on my Note 4. Posted some pics over in the thread on this topic for the Note 3 before I thought to check here. Basically there's a brightness and gamma gradient from top to bottom. The top half is perfect and the bottom half gradually fades to a point where you lose the first 8-9 squares on the lagom.nl black level test.
This one emphasizes the black crush, which can be visible in video content on a dark screen (and makes dark colored backgrounds fade to black towards the bottom):
And here's one on a white background. At first it seems like a white point issue (which I would tolerate since it's common on IPS as well), but it's a brightness gradient:
Between this and the fact that AT&T disabled the slider for auto brightness I'm a little frustrated with this supposed best smartphone display ever (I realize this second issue isn't Samsung's fault, but the auto brightness is unusable without that feature). I bought the phone at Best Buy which is mostly out of stock right now so an exchange isn't likely, assuming they even take this seriously as an issue.
My note 4 does not display this issue.
No issues here. Display looks very consistent.

Have you tried a dark background in a dark room? For me it wasn't that obvious until I did this (was messing around in Sketchbook). If the majority of screens are better than mine I'll definitely be trying to get a replacement as this is bothering me.
I just installed Lux to resolve my backlight issue and its settings menu background fades nearly entirely to black at the bottom.
*Edit: So far it sounds like this is an anomaly. You would expect places like Anandtech to report on it if they'd seen that amount of variation. I'm going to have a good time trying to convince someone at BB that this is a real defect though.
Erica Griffin talks about this issue in her Note 4 review, around the 20 min mark: https://www.youtube.com/watch?v=-OyNWrQJzMY
I got a replacement and it's perfect. No pink tint.
So, if you have the tint return it. Not all Note 4s are like that.

Thanks, that was quite helpful. I think in general it's easier to trust reviews on retail-purchased devices over mainstream reviews with PR department selected units.
I went to BB today and looked at the display units. All perfect, but then that's not surprising (every company gives their display/review units a second QC pass, even Apple). I'll probably head to the only BB in the area that has units tomorrow and see if I can do an exchange. As long as they don't make me sign one of those "no more returns" agreements I've heard about I'm willing to take another shot in the display lottery.

Good to hear! I'll post my results after my exchange attempt tomorrow. Aside from the gradient I am impressed with the display. Not as bright as LCD in daylight, but I was drawing on a black BG last night and noticed that it has deeper blacks than my Pioneer plasma.

Fingers crossed for you to get a nice one like mine.
Yeah, the blacks and colors are amazing on the Note 4. The whites are not as bright as the iPhone 6+, but they are fine and way better than whites on my Note 2. In all other respects the Note 4 screen is overall better than even iPhone 6+'s excellent LCD.
One minor disappointment is the very high resolution has made some emulators dog slow as they attempt to render at full resolution, i.e. PPSSPP and ePSXe using ogle renderer. Hoping the devs find a workaround, maybe rendering at half or quarter rest instead - that would still be higher rest than my Note 2 at full rest. :laugh:
What's the color of your device? Anyone have this problem in the white version?
my note 4 has pink tint
I have the same problem on my Verizon white note 4 but on top half of display. Replacement should arrive by Friday :/
You can replicate this by looking at the screen at an extreme angle, obviously the ones that see green and purple straight on are screen defects.
I have a white version and whites are perfect and too bright at high setting. I keep mine half way. The whites are better IMHO than the iphones. The colors more vibrant and, the sharpness is ridiculously sharp. I dont see how they can improve it. I only thing there should be a waynto adjust the color saturation, because basic mode doesnt do much on mine.
My Note 4 has the same issue. It almost looks like the while balance differs from top to bottom, but it is really the brightness that is different.
This is a photo of my Note 4 showing a solid colored image at #030303 (very close to black). It shows how different the pixels in the bottom and in the top emit light.

Looks like crap.

similar problem
I have a similar issue, though mine is brighter on the right side than it is on the left. Very noticeable with dark background in lower light situations as someone else mentioned.

IPS Screen/Backlight issue/bleed!

This being my first smartphone, I apologise if this question has been asked before and for generally being a noob, but hoping a recent answer would clarify the situation for me.
I know IPS screens for any type of device/product are prone to backlight bleeding, the reason I have a VA pc monitor. I did consider an amoled screen, but for the price, £300 and my intended uses, the G4 was the best option presently.
Without another phone to test it against and no photographic evidence for you guys my description is the best I can do. There are two points on the screen where I believe there is some bleeding present, but this is still subjective. The first is the along the top edge, where there is a very thin lighter strip of possible bleed, maybe an issue with the panel, where the info bar is normally present, that is lighter than then rest of the screen. I can notice it whilst watching full screen video, not always, when the bar is absent. The second is more minor, there are two spots on the bottom of the panel, either side and just above the LG logo where there is some bleed leakage, but minor.
I guess I'm asking is this common and worth the risk of replacing, or are the odds are I might get the same again?
Thanks.
Some light bleed top and bottom is going to be somewhat inevitable. On my phone it is noticeable if you look for it, but not too bad.
I have another issue with the panel itself not being uniform. The top of the panel (near the earpiece) is all bright and possibly on the touch of the yellow side of white. Lower down the screen towards the bottom left it goes towards pink.
Is yours OK in this regard? It is most noticeable with the phone in landscape reading forums like this.
I have a replacement phone arriving tomorrow to compare it to.

The uniformity on mine seems okay - using your suggested test on 50% brightness on this webpage, I have none of the other issues you mentioned (pink or yellowing), apart from that bright strip along the entire top edge under the front facing camera that is brighter and slightly washes out any colour/images on that edge.

Thanks. Another place it is noticeable on mine is in Gmail or any notification on the notification bar in landscape. Almost as if one side of the screen is a different colour to the other although you won't notice in photos or videos. Only on white/grey backgrounds.
It sounds like all you are seeing is the backlight bleeding through, this will happen to some extent on all LCD's. I tried screen test on the play store and on the black background test I can see a faint bar of greyish light right at the top of the screen. Unless you go AMOLED I think any replacement phone is going to look the same.

Hopefully a replacment will be an improvement for you.
I'll see a few days how this bleed works out for me. Would get an amoled, but the prices plus a lack of microsd card limit any options for me. Since testing lcd monitors, always try to avoid them now because of the panel issues that are inherent to this tech process.
Good luck on any replacment.

There's been a few good deals on the Galaxy S6 (around £325 unlocked) but all the reports of poor signal puts me off (and of course there's no micro SD). The G4 seems very strong in this regard, only phone I've ever had that works in a few of the blackspots round here (all other phones report no service) Some reviews even mention that it is a bit deaf.
AMOLED isn't without its own issues though.

All true, I've heard complaints about screen burn in on with amoled screens, some mentioned in the reviews of the Nexus 6P.

I don't think screen burn is as bad as it used to be. I had pretty bad screen burn pretty quickly on a Galaxy Nexus.
Here's my LG G4, can you see the pink in that? i.imgur.com/YjmtPtT.jpg
Sorry can't post links yet. Very poor quality image, taken on my work phone.

Yes, definitely around the middle-right-lower portion, pinkish presence even in that picture. You still within the retailer warranty/return period? If so, don't hesitate to return it.

It's not that obvious in real life, looks worse in the picture to be honest but I still can't live with it. It'll be going back when the replacement arrives tomorrow. Hopefully the replacement is fine otherwise I won't know what phone to get to replace it with. I can't get over how good the signal is now on it.

Replacement is way better. It's definitely a keeper. Has the slight 'light bleed' that you mentioned in your OP but the panel is at least completely uniform.
