Note II screen partially tinted

Hello everyone. Right below the notification bar, there is a tinted area going sideways. This appeared about a week ago. Only the display is affected, this doesn't appear in screen shots. When I get the device in landscape mode, the tinted area stays physically over the same pixels, so it's now upside down. I took pics of the phone by another phone. The quality is not so good but sharp eyes will notice it. Anyone had the same problem? Any ideas what should I do about this?

The first two are screenshots and in the last pic you can see bottom half of the username box is a darker tone.

Hi! It's probably screen burn in, common with amoled displays, I had it quite bad on my old phone. Caused by spending a lot of time on the messaging app, in which the part below the notification bar was grey, and the rest white. Brighter sections of the screen age faster.
I assume you use your phone in portrait mode a majority of the time?

I spend much time on tapatalk and yes in portrait mode. After reading your response my eye caught the bright blue bar of tapatalk 2s stock black theme. Probably that bar caused this because the screen is so dark with this theme but that blue bar.
But this shouldn't be taken as user error right? I think I should get a replacement screen as this phone has been in my hands for just 6 months. I'm still in warranty period.
What do you think?

It's not an error, amoled screens age this way, it's quite normal.
I understand it's quite frustrating, once you see it, you can't unsee it.
Especially in just 6 months of use, I noticed this on my old Galaxy S after a year, and realized it was because I was on an AOSP rom for a few months which had white messaging with a grey bar.
They probably won't replace the screen, either saying there's nothing wrong with the display.
No loss trying, they might be nice enough to give you a new display! :good:

I see... But one expect at least a year to talk about aging. It's no big deal for now but if it gets darker I don't think I'd put up with it.
Too bad I love this thing a lot but guess I'll have to avoid amoled screens for my next device...

Agreed, 6 months doesn't speak much off the quality.
I considered it too, but Samsung devices always have Amoled, and I like Samsung hardware, even though a lot of their devices are faulty, including mine.
The LCD is one of the main reasons I like HTC hardware, better color tone.

Samsung Korea replaces panels for free if they can see a burn in. People there get quite worked up about this issue on amoled displays so Samsung does replace them quietly. Heck there's even people who leave the screen on blue (apparently the best colour for getting burn ins) and get them replaced on purpose. Not sure about anywhere else though. It's worth a try visiting a Samsung service centre if you can find one near you.

Hey, that's good news. I'll try talking to a center when I get time. Thank you very much.

tip for you guys. this issue with amoled screen is a common issue. you can check you note 2's screen burn by doing this test, open the Phone app and type *#0*#, check colors Red, Green and Blue (blue is most commonly affected). Note 2 is my 3rd smartphone with AMOLED screen for me. the first 2 phones got screenburned big time, but I took extra care of this one. it has a little screenburn in the notification area but you can hardly tell the difference even when testing it with the test I mentioned above.
here's 2 things to avoid: exposing screen to direct sunlight, keeping screen to full brightness al the time. better luck with next amoled screen.

Thanks for the tip. Good to know that there's a way to avoid this. I use this phone as a navigator when driving so it must have gotten a great deal of direct sunlight. I'll keep the flip cover shut when not using the maps now.
Thank you all guys.

Thin Blue Line On Screen

I got a GPad yesterday and noticed a thin blue line that appears on the right side of the screen when I have been using it for a while (about 20-30 minutes or so). I returned the first and got another one today and it is the same line in same place after using it for the same amount of time. It does go away if I turn the tablet off for a few minutes. I really like the GPad and don't want to keep returning if it is a common issue. Is anyone else experiencing this?

We have two G Pad's in our house and they both have the blue line. Other than that though, the screens have excellent uniformity and color.

Thanks for your quick response Warp11. I did not want to keep returning it if others have the same issue. It isn't necessarily bothersome and turing off the pad is a quick fix.

Same issue here. It's actually to the point that I can't see it or it fixed itself.

Same issue over here,
get blue line on the right side of the screen, but it seem's to appear only when it's hot.
and also some white light bleeding on te bottom, but that's not really a problem
Contacted LG to ask if that's a known issue, but no feedback yet.

Same here, blue line on the right side when tablet in load (gaming and stuff), and mild light bleeding in the upper left corner, visible only on black background at low backlight.

has anyone who has had the tablet for a while NEVER seen the blue line? I wonder if this is a problem with 100% of the units.

I tried two from Best Buy the 2nd also had the blue line also after about 20 minutes of use. I also wonder if they all have this issue? I only notice it on mine when I play a movie with the video player app.

Hello guys...
I did some tests and I have also the blue line thing after 23 minutes watching full HD video from YouTube.
Then something else came in my mind. A simple but hard to think, to take a screenshot at the time was playing the video in portrait mode.
And guess what. The blue line doesn't appear in the screenshot (try it for yourself by taking a screenshot at the time you notice the blue line, transfer the screenshot to your pc and zoom in as much as you want - the blue line isn't there). This prooves to me that the problem of the blue line is just OUTSIDE the screen and NOT on the screen.
So if something happens it happens at point the display ends and OUTSIDE of it.
I don't know if this issue will cause problems in screen itself in the near future, but I think is a step now we know the blue screen isn't on the screen.

Has anyone else here written LG and gotten a response?

lol this just goes to show how much LG cares about this device. Sounds like every unit has this issue with the screen and they say it's "not a known issue". Sounds like people with the G Pad either need to live with the blue line or take it back b/c I doubt they can fix it. I know the line itself is really thin and hard to see, but I wouldn't be able to live with it and it also makes me concerned that there could be other issues related to heat over time.

LG G pad
Well, hello everybody! I own a g pad too and i finally figured out how to expose this hidden "ability: of the device..
I run icestorm benchmark about 5 time on a row and then i took a screenshot with my note 3 in a 90% dark room...Tomorrow i am going to contact LG for this issue too...Feel free to use the photos as you want.

Its most likely a design issue. Which I don't think they can fix it without recalling every LG G Pad.
Its not REALLY that bad, slightly noticeable when watching a video in letter box (when the background is black), but it isn't super bright so it won't really annoy you.
If you play games most of the time, you won't even notice it because as long as there is some color going through those pixels, you don't see the blue line.
The blue line is super thin, its like a line of pixels at around 1 inch long. And since this screen is super high res, the line is super thin.

I don't know what you mean by one inch long mine runs the whole length of the screen when it happens. As long as it does not get worse I can live with it I really don't even notice it anymore.

Guys i took the black version after DOA (the white one)..The problem is worse! The blue line is across the whole screen even if my tablet is cold...If i push it the blue line becomes brighter and guess what...I cannt put the brightness at 100% bacause "the device is overheated"...I have to get this for DOA again cause today is the last day of 7...
Lg hellas told me to get it for DOA but they didnt have ane other issue like this before..I send them the pictures and they couldn't believe their eyes..
Anyway, sorry for my bad english..i hope LG will do something asap..and for me?? I ia gonna try to take refund and not another pad again..When the new revision come out i see what i'll do because this tablet is the best VFM out there...High end with mid end price.

Guys if you remember the heating problem is Qualcomm 600's issue. F.e. galaxy s4 also had it and it fixed through software update.
Mine doesn't overheated at all after 40 minutes watching full HD mkv movie, or after 1 hour browsing. But I also have the blue line. I have the blue line without freaking any heat in back. So I think blue line thing is in all devices, but some users just haven't noticed.
The overheating think, I believe it's only in some devices and not to all.

So for the people in here who have noticed the blue line, are you keeping your GPad? I really enjoy mine but would like some input from others to see what you all are doing/planning to do as far as return, exchange or keep.

Screen Issue

There is a small spot in my G pad's screen where it's always bright. It's visible when the tablet is tilted on a certain angle. I've read several complaints regarding the G Pad's screen -- yellowish tint, thin blue line. Are you guys also experiencing the same problem?

Looks kinda like a "stuck" pixel (as opposed to a dead one, which would be black)

Yeah mine is yellowish too. It's really disappointing. I love the G pad tablet but the screen quality is just horrible.

It is really odd because it seems to be a software issue and not hardware... Mine is fixed with a quick tweak and it now looks fantastic. I wonder if I flash your kernel on my G pad if it will be fixed? Maybe they have multiple models or something... The tweak causes a lot of lag so it would be nice to have it stock. I don't want to go through the process of returning my G pad for a software issue.
Could you take a photo of your whites compared to another phone or tab like the G2. I want to make sure it is not a personal preference issue. For example I may see white as cool(more blueish than yellow) so if it is too warm I hate it, and you may like it warm but hate cool. Btw the app I use is called color test, just swipe until the white test)

I never had the blue line issue until i switched to the non-LG ROMs. I also seem to have lost the yellow tint since I switched.

I had the same bright spot on my first one, took it back to BB and got another, it was fine. Someone told me it was caused by pressure on the back of the display.

I have a bright spot just like that on my GPad as well. The spot on mine is in the bottom left though. I also have the blue line issue many people are talking about. It shows up at higher brightness more easily and begins after 20-30 mins of use. I could live with the blue line, but this bright spot may be more than I can take. I feel like for this kind of money a product shouldn't have any defects. And I've already RMA'd the tablet once to NewEgg because I thought it was defective the sound quality on the speakers was so bad. The new one sounds even worse, I think the speakers are just rubbish. Now I'm thinking about just returning the tablet for a refund. It's a shame because it really is the best non 10" tablet right now. 7" is too small to be usable. It's fast, its the perfect size, and I like some of the LG customizations, apps, and keyboard. I also liked the price ($250 during NewEgg cyber monday). LG seems to have a serious quality control issue on these tablets. The bright spot is unacceptable and appears to only affect some units. The blue line seems to affect all of them. If I was one of the lucky SOBs who scored it for NewEgg's thanksgiving night sale for $175 I might just live with the defects. But these issues at the price I paid make me want to return it. I may wait for a next generation Note 8.

I got my g pad today and can unfortunately confirm most screen issues.
The yellow tint shows up as soon as the tab warms up. Just for fun I put the tab in the fridge for a few minutes and the yellow tint disappeared.
Could it be some adhesive that didn't have enough time to dry out?

The yellow tint can be removed when using screen adjuster. Just turn up blue colour and the tint is more or less gone. App has to run the whole time though. Still waiting for a kernel to support gamma correction....

I don't think it can be removed and believe it is a hardware issue.
Take a look here http://forum.xda-developers.com/showthread.php?t=2556691&page=2
The warmer my tab gets, the bigger the blotch gets. With software you are probably just adjusting some settings to make it less visible. I think apple had a similar issue once.
Edit:
I just had the tab in the fridge for 5 minutes and the tint is gone. So it is definately a hardware issue. The screen is back to normal.

Galaxy Tab S Mura Effect Problem (Test yours)

I have been noticing that when I am looking at darker solid colors they sometimes appear to have a slight gradient to them. I know this is an AMOLED panel, so when a true black pixel is displayed, that AMOLED display pixel should appear completely black (as in, NO light is emitted). This is one advantage to AMOLED panels. So even at 100% display brightness, a true black screen should appear OFF.
So I created some test images in Photoshop to see to see how different shades of black and near black appear on the screen (I tested tones from 100% black to dark gray).
From my test, I found that my tablet does in fact turn completely OFF when 100% black is displayed. BUT my panel actually appears to have a slight backlight bleeding problem (Edit: Mura Effect).This is only noticeable when I am viewing colors that are very dark (but not completely black) and consistent. Also, It it's only visible in pretty dark rooms. I am not sure if I am going to return/exchange my tablet out yet.
I thought I would share my process for others to try to see if this is a common problem first...
Here is a Dropbox link to the files I made to test the problem:
https://www.dropbox.com/sh/wtfuazfn7i7z09o/AABvbRuA7-MUx_tF7xmmGSfAa
Method:
1: Open link up in the Dropbox app on your tablet (file sizes are full screen). Or feel free to download the files to your tablet and view them in the gallery app.
2. Turn screen brightness to 100%.
3. Make sure you're in a DARK room.
3. View files on your tablet at full screen.
Image 1 should appear 100% black (your screen should appear OFF). Image 1 is NOT going to be the image that will make Mura noticeable. Image 2, 3, 4 and 5 should start to appear slightly lighter as you scroll through the images. Watch out for inconsistent shade gradients like you see on my examples below (this is what tells you if you have Mura effect problems).
Here are what my results unfortunately look like. As you can see, image 1 does appear completely black (don't mind the reflections in the pictures). But the effect is pretty obvious on images 2 and 3
What are your results?

well first of all seeing my screen on full bright but appearing to look off was pretty cool. also on mine i did not have a bleeding problem and they all seemed to have a solid difference with nothing visible to my eye.
i have the 10.5 and had to put in portrait mode to gett full screen.
thanks

Well technically your super amoled panel cannot have backlight bleed because there is no backlight. What you are seeing is referred to as a mura effect and should not be happening with this advanced of a panel. It has been confirmed that some of the 8.4 units have defective screens. On my 10.5 unit all dark colors look solid with no mura effect at all. Here is one of your sample images on my screen. Of course if you view this on your tablet you may see the mura effect. View it on your PC.

No 'bleeding' here either.

I have a T700 (8.4) and have just testet you pictures, - mine also have some Mura Effect, however not as dominant as the ones you posted here. I can see on this link here that it unfortunately seams to be an issue on most of the units -> http://forum.xda-developers.com/galaxy-tab-s/help/users-feedback-want-to-buy-8-4-t2834969

Even if there is a problem if the only way to realize is to create conditions no one would ever encounter (100% brightness in a dark room on only specific backgrounds) is it really a problem?

T705. I noticed 3 green dots though.

I do not notice anyyhing like that on my 8.4.
I would get an exchange if you still can. Never know what the ramifications in the future to the display may be.

Exactly this. Some people have waayyyy too much time on their hands, I don't know how they manage to live their lives if this sort of nothingness is enough to trouble them. What exactly are you intending to do with this tablet, color time a Hollywood movie?
Must be a real killer for some people every time they have to change channel on their tv, I have to wait 0.4 seconds for the next station to come on. It's terrible.

Nobody can see this with their naked eyes.
Everyone that posts about this use ultra high iso pictures to show it.
Its a non problem.

It actually is pretty noticeable even at 25% brightness when you're just using the tablet normally. Now it doesn't show up everywhere. You can see it pretty easily in the notification shade and in the settings menu. Or when you open up Chrome with no tabs, that background is not perfectly solid and I notice it every time. You can also see it on darker full screen photos too.
Still not sure if I care enough to exchange it. Although, I am very picky about image color representation as I am a photographer and this panel on AMOLED Photo mode matches my calibrated monitors pretty well, but that dark gradient just bothers me sometimes!

Is yours also the 8.4 version?
3 I work with all have the 8.4 (T700) version myself included. All have visible Mura effect at normal settings. Samsung run an ad campaign here in Denmark, where you can buy and try for 30 days one did an exchange - but same result, visible Mura effect - however under normal working conditions is not a big issue.. Bur as a still photo viewer I understand your point.

Mine has dark mura at top right corner with dark banding at the lower screen

Yes, I have the 8.4 inch version. If it really is that common, I may just keep it. It does bother me, but overall I am happy with the tablet and am happy with the battery life. Not sure I want to chance getting a new one it it not being any better...We'll see though.

These are the conditions to make it easily noticeable. I on my hand did notice the issue on regular use of the tablet:
- First noticed it while reading an e-book, the tint of the background was not homogenous.
- Then I noticed it while browsing the tablet options: "huh, the gradient on the background is not regular.. oh wait, it's not supposed to be a gradient".
- And now I notice it while playing movies, when the scenes are dark.
100% brightness is not a requirement for it to be visible. Actually, minimal brightness while in the darkness works very well at revealing the issue.
However, it is extremely unlikely that someone ever notice the issue while using the tab in daylight. In my case, I use it mainly in the darkness, and often get to see it.

Damn you OP, mine got it too...anyway, it isn't really noticeable with most content so I just keep mine since it seems very common anyway.

That's defective. You guys should not be satisfied at keeping it like that. I have no such effect. I'd take it back if it were mine. I didn't pay $600 for a tablet to have a defect like that

I don't know if it's defective, but if it is it's a defect that affects most AMOLED screens and all of the Tab S 8.4 I could test it for (3 of them). My Galaxy SII is affected as well, so is my PS Vita. And my friend's. And his Note II.
I returned my unit twice, once through the online store and once through the physical one, all of them suffered from Mura effects. Either I am utterly unlucky, or a large amount of the tabs are affected.

Screen backlight uniformity issue?

I recently got a Zenfone 5Z from Flipkart and upon first boot, mmediately noticed that the bottom left area (where the Navbar is) is ever so slightly darker/dimmer than the rest of the display.
The issue isn't noticable in certain lighting conditions but now that I know where to look for it, it is a bit visible in lower brightness or dim lighting conditions.
Raised a replacement request in flipkart who arranged a tech visit. The technician who arrived was pretty dumb and took pictures of a screen test which he did while standing in the daylight. Then said, he couldn't see it but will forward it to his seniors. After a few hours, the replacement got rejected.
Now flipkart says, I can still place another replacement request until the return window is over.
Apart from this minor issue, the phone and display is amazing. But I need to know whether this is a defect before going the replacement route again.
Please see photos attached. Noticable on white screen and white UI background

Hi, Even I have the same issue but in different areas.
I have color differentiation or darkening of backlight at bottom and right edge of the screen and it is getting noticeable easily day by day.
I'm going mad at this phone.

The dark shadow on mine seems stationary n hasn't increased or decreased but as I know where it is, I keep looking at it. Sadly, the jeeves technician said he cant see it. And they rejected my request.
Did you not try a replacement? Or is the replacement also the same?

OMG I thought I was the only one with this issue and people keep telling me I am nitpicking but this is driving me crazy (I'm very particular about display quality).
Raised a replacement request as well, and the technician did the same thing - took a photo and shared on some Whatsapp group - and then cancelled the replacement; although in my case the technician did acknowledge the issue but said that as per the company's policy this does not qualify as a manufacturing defect - most likely the display had some extra pressure applied so is a bit misaligned.
I'm guessing this is present on recent batches as did not read about any such reports before buying the device. Anyway, the Jeeves guy advised me to visit Asus service center and get a DOA sheet from them and raise the replacement request again.
Pissed about this issue as the phone is otherwise perfect... It's just that the bottom 1-2 mm appears darker - like a shadow/warmer color tone, especially in white backgrounds like Settings, Google feed etc.

But flipkart still gives the option of applying for a return if you're not satisfied with the tech visit. Did you not try it? I feel this issue isn't reported much as people aren't noticing it or don't care enough to see that its an anomaly.
Almost all my previous phones had perfect screens so thats possibly the reason why I noticed it immediately. As the issue is subtle, there is a high chance Asus can say it is within acceptable tolerance levels. Especially as it doesn't show up in colored backgrounds and more in white UI elements.
As a matter of fact, I am actually scared of getting a replacement as I fear I may get something even worse with the whole display lottery going on. Because after a second replacement, they only offer refund which means I lose out on the deal I got.
I was looking through people posted images on Flipkart reviews and could see this dimmer bottom area on a few phones. Guess people aren't noticing it.
Also when did you get your phone? I got it last week. Its Aug 2018 Batch Manufactured in Indonesia.
I know there are some being made in China too. I would assume the Chinese ones are a higher quality if we take the Redmi Note 5 as an example
And this issue is very difficult to photograph as a camera doesn't see it as clearly as the naked eye.

Yeah well even for a return they need to acknowledge the set is defective. Besides, like you said, I will miss out on the deal if I return it.
I'll probably visit the service center this weekend and see what they say. Even if they offer to fix it by replacing the screen or something it's fine. I just don't trust Jeeves' judgement - what if the issue is serious and gets worse over time... As of now I can live with it (just hurts my OCD ).
Will update here about the visit.

I too got it in BBD sale, delivered last weekend. Mine is from June 2018 batch, also made in Indonesia. So I guess either all Indonesian units are like this (which means issue is similar to Poco F1's), or this has nothing to do with batches and are rare cases. Ironical that I chose this phone over the Poco because of the display problems in the latter...

Hiw bad is it for you? Can you post some pics? I'll post a few I could manage to click once I get home from work.

Not having a Problem in my Device.
I bought the Phone in Flipkart's BBD Sale. There isn't a single problem on my device and it works flawlessly. But i cannot find where my device was manufactured, if its been manufactured in Indonesia as you guys said then it might only be a problem for some Devices out there. But i have been noticing a bug in the Wifi where it will connect on when we dive into the Wifi settings and Fingerprint is Slow, so is the Face Unlock where we have to swipe up just to unlock the Phone after your face has been recognized. Other than that the Phone's pretty awesome. I am loving it.

Ok, so visited authorized Asus service center today. The guys there were polite and did not try to force the notion that something was wrong with my eyes lol. The technician there has a Zenfone 5z of his own and he showed me on his unit too the bottom shadow is present. His explanation is that the display driver is wrapped around at the bottom chin and that's what creates the shadow - nothing to do with backlight or alignment of the display. So all units would have this shadow effect and no point in getting a replacement. The guy suggested I drop a mail to Asus as feedback about this design choice
So I guess I'll just have to make my eyes get used to it because rest of the phone is perfect and I won't get anything better at this price.
 @satishp If you absolutely cannot stand the issue you should probably get a refund and buy a different phone (although maybe a lot of near bezel less displays have similar issues). Or you have to live with it - no point in getting a replacement as all units are likely same. Oh, and btw, the technician's unit is manufactured in China (at least that's what he told me), so it's more of a design flaw than a batch issue I guess...

@khayalmania
Thanks for the update brother. Its a relief knowing its not a defect. Guess we'll have to live with it then. Just to confirm, I have attached photos of my phone's screen now. Sorry about the delay. Is this what you are having as well?
Anyway, I have no intentions of returning for a refund as this was a pretty good deal. This device is even better than the OP6 in many aspects. Nothing else comes close. The issue is quite subtle. Only visible at lower brightness. The shadow isn't very prominent in higher brightness levels.

Sorry man can't see your attached photos. Maybe because I don't have enough posts?...

It's called "shadowing" and is fairly common on the 5Z. It's most noticeable along the notch and bottom of the screen. I'd rather have a little shadowing than lightbleed or burn in.
