[Q] Strange marks beneath the screen

I’ve a strange problem with the screen of my Note, I noticed this when switching off the phone in a complete dark room. The screen turns dark grey for a split second before switching off, this is when I noticed some strange black marks beneath the screen.
I made a jpeg to replicate this problem (1st attachment), along with a screen capture of the marks (2nd attachment). Can somebody please download the picture and check to see if there are any marks on their phone?
You need to be in a complete dark room for this to work, it helps if you turn the screen brightness to 100% and allow a bit of time for your eyes to adjust to the dark.
I also added roughly what the marks look like.
Many thanks
P.S. this does not affect the screen in normal use.

I have noticed that too....
Edit: forgot to mention that it does not affect usage in anyway

Why.....
SH!T, not this crap again. The Galaxy S2 has this at a greater extent, but I was LEAST EXPECTING this on the Note, especially since they JUST starting manufacturing this model. I don't even think the demand is as high as the S2. I'm having mixed thoughts now. Those marks are NOT normal.

hi...is your phone UK or EU version?

This is the biggest manufacturing defect of the season! Go to the Samsung Herculus (T-Mobile S2) Forum and you have over 500 users observing the same exact problem! Samsung is carelessly sealing the back of the AMOLED display panel, therefore you will see lines and blotches everywhere. This is absurd!

I guess it could be a problem, but to be honest with you, I don't have any interest in trying this.
Go to a completely dark room and turn the screen to 100% and look for defects? Uhh, what?
When I'm in a very dark room, I find 3% quite comfortable, thank you. (10% brightness * screenfilter (30%)

Hmmm.... so something that you can only see when you are switching the phone off in a completely dark room is "the biggest manufacturing defect of the season"???
I understand that when you drop hundreds of £s/$s/€s on something, you want it to be perfect, but something that can only be seen for a split second as you turn the phone off in very specific circumstances, scarcely warrants such a title in my opinion!
I can certainly think of worse - lightbleed on Asus Transformer, or Newtons rings/oil click on the Galaxy Tab 10.1 for example, which (if present) can be seen during use.

I agree with foxmeister. Why try and find a fault when there's really no fault there!
So you've got dots on your screen when in a completely dark room, with screen set at 100%, that lasts for a second or two......so what! Don't sit and stare at your phone in the dark is the answer. Then the problem will go away.
Jeeez, some people are never satisfied or happy.

Thanks for the feedbacks, I have the EU version from amazon.de.
There is definitely a fault with either the screen or how it was put together, otherwise I'll not be able to notice it. Those marks does not show up on my Galaxy Tab 10.1, the original Tab or any my pervious mobile devices as far as I can remember.
I did note this don't affect the screen in normal use. Also the 100% brightness suggestion is to make the problem easier to spot, I normally have the screen at 5% in the dark, and we have no control over the brightness when the phone is switching off (when I noticed the marks).
I started this thread to find out what is the course of this problem and how widespread it is before deciding if I should send it back to Germany for a replacement/refund.
BTW, under EU consumer law, we have 21 days to return the device either for a refund or replacement from the seller, after that we might have to send the phone for repair.

Sounds like there is a manufacture defects with the EU version?!

Head over to the International Galaxy S2 and Galaxy S2 (T-Mobile) Forums and the answers behold. Hundreds of comments stating the same exact issue. I'm just surprised how this slipped into the SAMOLED HD display. I don't recall the original Galaxy S (which also had a Pentile Matrix) having such an issue, or did it?

I have a Galaxy S II, and regularly frequent those the international forum, and I've not seen this come up as an issue (though I don't disbelieve you that it probably does somewhere). I looked in the TMo US Galaxy S II specific forum and I did find such a thread, but I was unwillingly to pour through 50+ pages to see the final outcome as it was filled with people who have the issue, don't have the issue, or have the issue but don't care.
I've not noticed this issue with either my Note or my Galaxy S II, and I'm not going to go look for it in artificial environments that I'd typically never be using my device in.
"If a tree falls in a forest and no one is around to hear it, does it make a sound?"​
According to the OP, on the Note, this only appears for a brief moment whilst the phone is being switched off in pretty much total darkness, so my point is - does it really matter?

Dave

Well, many EU owners are already reporting black spots on their Note!

I was lying in bed last night and saw what you are talking about. I think. I has used my phone heavily for the last week and didn't notice anything else.
So I suspect we all have it but uhhhhh whatever.

See this link for another photo of the problem:
http://forum.xda-developers.com/showthread.php?t=1337499
The photo is taken with a small Canon camera, with ISO = 200, and a 15 seconds of exposure time.

Post removed. I started a new thread.

The Note is going back to Amazon. I was able to see the some of the black marks against black border when watching film in the dark last night with the screen brightness of 5%.
I was going to keep it before it started to affect my normal use, lets hope the replacement has less or no marks.

purple tinge on screen

when i reboot my note and it goes to the AT&T boot logo, i notice a purple tinge on the bottom half of the screen. anyone know any test i can run to test it further?

not at all. explained the situation and said i didn't notice it until i finished setting up the phone and when i went onto the browser i noticed it and just called them up. they said it shouldn't be that way and they were gonna order me another replacement. getting it tomorrow from fedex. had the option to bring to the store and getting it replaced there but didnt want to deal with the reps in the store.so i had them order it for me over the phone.

I notice if the brightness is all the way down when scrolling white text on black I see a purple tint

I see it only at boot when the AT&T logo is up. It happens to only affect the bottom part where the animated gradient is.
I'd like to have more people teat this out. Maybe a good test would be to turn the boot animation upside down somehow, and then booting it up. It could just be some glitch with it running that animation or it could also be baked into the image.

I tested using Display Tester app. Used color chart #808080 at lowest setting number 1, in a pitch dark room. The lower quarter towards the home button showed to be slightly darker. Couldn't emulate this in any other color's. Seems normal.

Permanent red tint on screen

Hey guys,
I started noticing bit of red tint on lower half of the screen.
I am aware viewing angle make difference, but no matter which orientation/angle I look from it is still there.
Anyone else having similar issue?
Also, if this is a defect, is this the kind that retailer usually replace for consumer?
It is giving me headache looking at the screen for a prolonged period even though the tint is not severe.
Sent from my SM-N910U using XDA Premium 4 mobile app

Its very, very slight on mine. Nothing that would make me consider returning it though.

Also, screen tint shift based on angle is a lot more frequent than my s3 (i9300). I tilt note4 by even 5deg and I see colour shift already, but nothing like that on s3.
Can someone confirm this please.
Thank you.

Yes, my phone does this. However I've checked a lot of shop display units and have noticed many are better and some are worse than mine. The sad fact is that there seems to be a bit of a screen lottery going on and it's luck whether you get a good screen or a bad one.

You can try it. If they have a display unit that is obviously better than your current one and they can see that. Problem is you might end up with a replacement that is just as bad or worse!

Thats been the case since the Galaxy Note 2, even my note 3 has a slight reddish tint on the top part of the screen.. most if not all the units ive seen either has a red tint or a more warmer color tone at a certain part of the screen. People have accepted this as a norm.

Yeah funny it is a norm for Note series when it is not for S series when both using same display technology
Sent from my GT-I9300 using XDA Free mobile app

Agree. My old s5 was much better with colour shift and tinting. As are the new tab s tablets. I'm disappointed with the note 4 screen.

Have you tried setting the display to photo mode?
I am still wondering if we talk about the same phone, my Note 4 has no red tint and no color shift at all, no matter how much I turn the phone.
Also looking at a totally white/red/yellow picture, I can't find any part of the screen that is warmer. Some people also reported that greys look terrible, I can't comfirm that for my display.
Coming from the Nexus 5, this display looks so much better in all aspects, I am still stunned after using the phone for 3 days now.

There seems to be quite a disparity between phones. Some are good, some are bad. That tends to be why people are having different experiences.

It was the norm for the S series up until the S4 came out. The S4 was the first Samsung screen since the Note 2 that had a very nice and even screen.
S1, S2, S3, Note 1, Note 3 all suffer from poor screen uniformity. Guess you can add the Note 4 to that too.
This worries me as I'm planning on skipping the Note 4 for the Nexus 6. Samsung will already be giving Motorola last years Amoled tech, and stretched across the bigger screen the unevenness will be even more obvious.
Especially now that Android Lollipop will be mostly light grey everywhere! Amoled's worst nightmare.

red tint?
What red tint, is this when the screen is on? off? I haven't noticed any red tint but now I'm worried...

Wow, if you do not notice it - do not find a reason to notice it. Be happy with your device.

My display is a very slightly more blueish/pinkish towards the top half, specifically the top right. It's only noticeable on white content. It's subtle enough that I won't go through the hassle of getting a replacement especially since the replacement could be even worse... At least my display has been brightness and no banding or anything. Overall though, this display is simply phenomenal. Hopefully these slight display issues will improve as time goes on, although the screen on my S4 was very uniform, doesn't even come close to the performance of the Note 4 screen though.

Seems like the problems are much less pronounced that the typical uneven backlight of LCD?

[Q] Static lines & bands on screen. Yes, please help.

Guys,
I've tried 3 different phones from Flipkart. The first one had the famous yellow tint issue which was down to a minimum in the next 2 devices that i tried so I guess it all depends on luck. But as luck would have it or OCD , I had new issues with them.
Both the replacement devices that I have tried so far have these 2 issues below:
1. Weird horizontal bands visible across the screen on light backgrounds (white/grey) most prominent on low brightness. They really annoy you when scrolling through your Twitter feed or any apps with a white background (Most on Lollipop!)
Best way to check these are in the default android dialogs of WiFi password or language choice.
2. I see static lines horizontal lines on the screen everytime the screen is touched and they disappear after 2 seconds of the touch. Again easiest way to check this would be to open the gallery and pull in the hamburger menu from the left. When touched to pull, mine shows prominent static/disturbance sort of ripples.
Can you guys check and tell me if these are common issues since both my replacement devices have these & I am really not upto trying another device after all the hassle.
Thanks.

I'll see the horizontal lines as well on light backgrounds, I just assumed it's a side affect of amoled.

Perhaps the lcd is defective?

Can confirm that my screen also has the issue #1. I always thought it was probably a large AMOLED screen issue. Never faced issue #2 though. I also got mine from flipkart.

Issue 1 is what bothers me the most. Scrolling on white backgrounds is annoying, you feel these bands are not moving & look prominent.
Even more worried since everything's going white in Lollipop.

Though I dont have a similar problem but I am pretty annoyed with my purchase. My first device was replaced since it developed screen-burn within few days of usage. Surprisingly, the second device has also developed screen-burn after 10 days of usage and the nav keys are permanently embossed on the screen which can be clearly seen on grey backgrounds.
The strangest part I found about both the devices was they were turned on right out of the box One click to the power button and the phone was already in the setup mode asking to select a language. White color reproduction is way off on this device and looks pale yellow instead of white I somehow feel that I should have stuck with my Nexus 5 instead of falling for this. At-least for now, I'm done with AMOLED's

So have you returned the Moto X?
Motorola seems to have major QC issues. Distorted speaker, yellow tint, weird lines and burn-in.
It's a great phone but the screen has major issues. I am on the fence now about trying a 4th replacement device but worried it'll have more issue.

They are not there all the time. Only on light backgrounds. Best way I can describe it is if you've ever seen a plasma TV that gets horizontal purplish lines going vertically from a color source on an all white background. The horizontal lines on my phone follow the dark letters/images as I scroll up and down.
And I actually RMA'd the phone today because of it.

I had the dark horizontal bands on my replacement device they sent for the back separating. They were very prominent on light backgrounds and very distracting. I chose to keep my original device because the screen is perfect on it. I didn't want to take chances with replacements beyond that. I took pictures and notified Motorola of the issue.

Oh, I've been pretty unlucky so far in that case, haven't got a screen without these bands. Well atleast there is hope.
But there's the same concern, will the replacement be better or worse than the one you have. In India, we have to hand over the device at the same time, so cannot compare the two devices.

So, I have not heard a thing from moto about my RMA label. On the site it said I'd get an email in 4 business hours, well all day and nothing. I'll have to call tomorrow I guess.

Well... Moto has no record of my RMA and I lost the RMA number because I took a screen shot and the pic didn't sync before I blew my current phone clean. They tried my IMEI and SN and contact info, it's like it never happened. They said they could try looking at the RMA number, but, I don't have it. No confirmation email either at the time of entering it.
So, I'm not going to bother again right now as others have said the replacements do the same. I got the two year warranty, so if the screen does eventually go dead, oh well.
What I will warn others of, is to WRITE DOWN the RMA number!

My first device was perfect - but I returned due to a scratch on the wood back. Second device is half yellow, half white tint with horizontal lines. It's like playing the lottery because the qc is still awful on amoled. I wouldn't mind if the full screen was yellow even but the half and half is terrible. Yellow can be fixed with color tweaks and wasn't all that bothersome anyway.

I have one dark line across the screen. I chatted in with them and I have to call them and ask for the REST department since mine was a custom one.

I've seen this once or twice, it appears to be when the phone is on 2G and data is on 900Mhz LTE.
But I can't say it's very visible, I can barely make out a pixel or two vibrating in very specific settings.
What's your model number?
I have the XT1092.

Yep even I have the XT1092. I am trying to live with it for now. Have till Dec 10th to decide whether I want to risk another device.
The bands across the screen bother a lot more than the static lines. Hope Lollipop comes soon so I can make a final decision.

You should try to capture it on a video clip, my lines are just barely visible in low light.
Film it and send it back for warranty with that video as proof. And post it here, I'm curious to what it looks like.
I'm pretty sure it's the LTE radio, because I can just barely make out the noise in my computer speakers when it's pinging the GSM tower.
Much like when old phones use 2G mode, but at a way faster rate and not as loud.
You might have gotten phones from a batch where they forgot EMI shielding or something like that.

[Discussion]Screen Burn-In/Stuck Pixel.

Ive seen no threads on this issue so I decided to make one! But I wanted to know if anyone had any! Personally I had one stuck pixel on my tab s. Yet it was really hard to see I later got it fixed by doing a stuck pixel remover video for about a couple of hours and later installed discreet blue theme. Now its not there! I own the tab s 10.5 Wifi.
So... Has anyone else got a stuck pixel or an image burnt into their screen? Let me know below! Could be useful for others buying this tablet!

I've had the Tab S 10.5 LTE since release, use at least 8 hours daily for work and haven't got any issues in terms of the screen degrading like burn in or stuck pixels, have thoroughly checked to be sure, might have just been a one time thing, generally take years for a burn in on Amoled but even then I have had other AMOLED screen devices for years without a problem

No burn ins on my unit as well , im using the 8.4 as my primary phone and gps. Im always at 1/16th brightness. I also have a 4 yr old 7.7 slate, no burn ins as well. Seems like newer amoleds are not that prone to burn ins. Just to add, im using an all black theme.

Somehow (turning brightness all the way up all the time) my friend burned in a new note 2 in about 3 months. He used his phone a LOT as well.

My Tab S (about a month old now, auto brightness below 10-20% using Velis Auto Brightness, not much used) is perfect for now. However I saw the two 10.5" samples heavily burned at the local mobile shop. Also saw two months old Note 4 heavily burned at the same mobile shop. So it seems burn-in problem with this latest amoled screens still remains.

Thank you guys for your response! Yeah turning the brightness up to 75‰ is how I got mine. That was when I first got my tablet and had it on 75% for the whole month. I want to walamrt the other day to see the samples. The screen seem imrpoved from when I got mine. I will try to use a autobrightness app

Thread should now be a discussion thread about the burned in pixels. Guess I made it look like a question. Thanks forum mods for telling me about this problem and moving the thread back!

I assume this thread is for burned-in and stuck pixel questions/discussion?
If so: I just went to a couple of local stores to test out the Tab S, with an intention to bring one home. I didn't so far -- all devices (4 in 2 different shops) had pretty severe burn-in from the demo programs that Samsung installs and runs on the devices in the store. A couple of them so much that it was actually disturbing for things like browsing plain web pages (white background); you could read the "inverted" text that had burned in.
One store anticipated the device had been on for 10 hours a day since somewhere August last year, which would make it around 10*6*40 or about 2.400 hours of use -- presumably close to max output on the display in "demo mode".
This caused me to hesitate... is this a common problem with the devices, particular to early models, or just something that happens if you run it for too high output -- or will it happen eventually to all devices? A life-time of less than 2.000 hours seems quite low to me in any case.
Also, when/if it happens, are there any ways to "reset" the screen again, or is the damage permanent?
I have a ~2 yr old S4 that does NOT have any burn-in, but I also use that much less, not at 100% brightness and usually with varying content on the screen. I guess the display technology is similar even if the Tab S is a much newer device.

I never had burn in problems in any Samsung amoled devices (since S1).
Just made sure box was sealed and auto brightness was always on.
Actually, I personally have a worst experience with LCD with light bleed and other issues.

Yeah, No problems with my 10.5" Wifi , I watch a lot of Animi and always run it fullscreen, so no black bars, also i set brightness to auto -5 when i am using it indoors.
No stuck or dead pixels, fingers crossed.

@pacc @tinderbox(UK): That sounds re-assuring. Sounds like it's still safe to go ahead and acquire the device (in my case probably the 32GB WiFi 10.5" edition). Hopefully this is the general experience by most people then.
On the LCD bleeding, then yes, that can be quite annoying too!

Just be glad you did not buy the 8.4" version as that is having some problems with the display that might affect some people.

I have 8.4 version and the screen is in perfect condition.

You need to use one of the screen test app to check for any problems with the screen before you buy, or the time runs out for you to return the tablet for a refund.
Some people are not bothered, good for them.
John.

I'll test it out thoroughly while it can still be returned. Thanks for the heads-up on that issue as well

If you really want to find every possible quality problem with the display, view a light gray screen in the dark, using a screen test app , set the brightness to low, look for circles and clouding, as well as dead or hot pixels.

I have an S4 I bought used and have used for about a year. It is getting heavily burned in. I am questioning how long this display will last. Hopefully by the time I need to replace it the screens will be cheap

What was burned-in on your S4 , notification bar?, home screen icons? , were you using an navigator app? , how high did you have you brightness set?
Using an low brightness setting can reduce the change of screen burn-in, but if you live in an sunny country you most likely have the brightness set virtually to max to allow you to see the screen outside.
Thanks
John.

I decided to check for stuck pixels on my Tab S again. Turns out, I have 3 stuck ones now! They are really really tiny that I can even notice them. Took me a minute or so to search for them. In order to see them, you have to use a holo background and not full black ones. You would have to find an dark gray image or something like an inverted app but isn't full black which is a good thing for me I guess. The good thing is that they don't appear on bright colors (red,blue,white,etc) which I personally couldn't see it. A holo background or gray image is when I can see it the most. When I put a black image, its fully black with no stuck pixels in sight. So that could mean they still work and turn on and off fine. So I'm thinking it's just stuck when displaying colors other than black.
I've kept my brightness 1/4 bright all the time, only used it for watching videos and browsing the web mostly. It's been one year since I bought this and I personally don't mind it. This is what I've seen so far
Edit: using a screen filter app to darken the screen on an holo image made it show the most so I can see. This lowest stock brightness doesn't seem to show a lot unless you get close to the screen.

A couple of weeks ago a guy bought an demo 10.5" and it had an perfect Samsung logo and stripe burned almost across the entire center of the display, the worst i have ever see.
He was asking would burning in the inverted image reduce the burn-in, I found the exact Samsung wallpaper responsible and inverted it for him, but i never heard anymore, it really needed an new screen.
