[Q] Correct terminology for G-Note screen issue - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Dear forum members.
I know what you may be thinking this is yet another thread on Galaxy Note screen problems, I couldn’t bring myself to post in the existing thread only to have it be drowned under the 1,300 of old posts http://forum.xda-developers.com/showthread.php?t=1336187.
I’m not looking to fix this problem myself I simply need the correct terminology to describe this problem to a Samsung engineer for what will be the second return under warranty.
Display:
E.g. in portrait mode very fine small red pixels peppered to the top of the screen under the notification bar spreading out thinly to the bottom right, most visible with a gray or white background apparent with screen set on lowest light setting and or when in a low light environment.
I appreciate that this may seem a petty concern why not simply make the screen brighter but given my eyes have a sensitivity to bright lights this is not an option.
My phone has apparently undertaken a complete diagnosis and service or at least that’s what the letter from Regenersis service centre said.
In addition to my main concern above I list the bellow only for completeness of this report as they may be connected with the above screen issue:
1. Strange nuanced behaviour of the automatic brightness which turns my phone into a mobile disco.
2. Banding on low resolution images.
3.Backgrounds especially white changes shades for example.: it could take a pink-ish shade or a green-ish shade or a light blue one.
My sincere thanks for taking the time to read

This post might be of assistance to you. I'm not sure. I haven't seen these problems.

Thanks missed that one have now bookmarked that page in regards to banding on low resolution images.
But unfortunately I don't believe there's any direct relation to my odd little red dots in terms or phrase that could be adapted for my purposes or at least none that I can see, but I'll need to give it a thorough read through to be certain.

Yeah, probably not. But, if you contact Samsung, I'm sure you can just describe "little red dots" and where they are and then Samsung will test it out and see.

Rose tinted glass
I've already tried to contact them although the Samsung customer service people try their best to be helpful, nor Samsung or it's employs can officially acknowledge this or any of the faults in my thread to do so would probably mean they'd have to do a mass recall of a lot of Galaxy Note's sent out.
The only thing they can do is recommend I make a service request which is what I'm doing for the second time.
The problem is the fault is so innocuous and almost invisible under normal bright working conditions that the engineer's can't see it, But once you've notice this fault it can be quite distracting it's almost as if half the screen has rose tinted glass
I guess it wouldn't hurt to pester them again I'll try and be more direct this time.

Well from my point view
the screen technology is led " light emitting diod"
this technology uses RGB colors , red blue green.
In every pixle there is a mixed of RGB .
Some of the pixels get damaged ; REASONS:
phone fall down.
Mnufactoring malfnctioning process in the screen.
expect anything that would hurt you screen
and if your device is still under warrenty . you are good to go
i hoped i helped

XPERIA Screen/Backlight Problems

Hey guys and girls,
I got my brand new X1i on an O2 contract today, ordered through the internet.
However, when switching it on, the first thing that stands out is the screen isn't all black. The upper right hand corner fades to like a dull greeny tinge as if its under pressure or something.
After fiddling around with it, it seems to be the backlight as in bright light, the colours all look fine and black is black. This is also the cause if the backlight is put at it's dullest, but it's most noticable when its at it's brightest.
Is this a issue with all Xperias or just mine?
And is this serious and worth contacting O2 about or will it be okay?
BUMP.
Could anyone tell me simply if this is a common problem, if not, I'll ring O2 now.
A quick reply would be nice
I haven't seen it before and I haven't seen it reported before. If you think it looks out of the ordinary, too much to leave it be, you should indeed phone O2.
Cheers, I shall call now
Post a picture so we can compare and lets us know how it turned out, mkay? =]
Heres the best photos I can snap.
The first two don't really show it well, but the third is the best.
Trust me, when you first switch it on and the Sony Ericsson logo appears, the whole screen is black and that corner fades to that dull green colour. It stands out quite a bit, it's also noticable on the Panels screen.
If you have a dark photo showing, it can affect the colours on that too.
For such a pricey phone, I expect it to be flush black across the screen.
(They're big, so I left them as links. I left them big to show the detail)

I just got off the phone to O2, they get the phone from a third-party so I am expecting an email from them. The woman on the other end said, most likely they will swap it for a new handset at the door, or take it for repairs....but it will say in the email.
Ah, classic case of backlight bleeding. Send it back and you'll get a new one.
Well, hopefully, before next week is out I shall. Just waiting for that elusive email, they said I should have received it by Monday.
Thank you for you're help, I appreciate it
There was a thread on this, some have it too.
I have it as well, black light bleeding. I dont really mind it much since I rarely notice it.
Ive decided to leave it alone since my X1 is unlocked and it'd be a massive hassle to send it away to SE.
I'm pretty sure its common. Even high end LCD TVs have the problem sometimes.
I had it on my first x1 (which I dropped and got a new through insurance), and I've also got it on my new x1.
However, I barely notice it, so I'm okay with it
I wouldn't mind so much if it was white but its a green colour, thats more annoying.
It's gonna get sorted anyway, most likely, they'll swap it at the door for a new one.
I was looking for information about the SPB mobile shell and found this thread.
I also have this issue with the top right corner of the screen, especially when I switch the phone on (on the black startup screen with "experia" written in white).
After startup, I don't really notice the issue since this area of the screen is almost never black (except when switching panels and sometimes when watching videos, but it's hardly noticeable). I'm now wondering if I should return it or not, I got the phone on tuesday and already had to do a hard reset (and reinstall everything I had just installed before) because I couldn't send or receive text messages! I really hope this won't get any worse...
(My phone is a french version, and my carrier is SFR)
Ive had the same issue w/ one...i just returned to BestBuy yesterday and now the replacement is also doing this as well...1 day later
Me too, bugging me like crazy, but seems to be quite common.
- Anthony
Mine has it too but its really not a big deal. I've only noticed it on bootup.
Yeah, don't mind it on startup - who watches it start up?
But I notice it when using the camera (in the black border) and
when switching panels, that's where it's annoying.
- Anthony
yeaa, i got the same problem too. Went over to the sony ericsson centre and they don't have a clue what it was. They said they'll look into it, and thats it. No replacement.
Not happy
i live in indonesia by the way..
Mine too has the issue. Both upper corners are bleeding greenish. It's obvious when the screen is black, not only on start-up, all the time. For example, look at it when playing a movie trailer with really black scenes, it's there.
It has to do with the pixels, not the back-lighting, from what I understand of TFT functionality.
Remember the dead pixels issue on TFT screens? Well, the dead pixel means the transistor of at least one color out of the 3 (RGB) is dead, either locked closed or locked open (anyway, not being able to modulate the light intensity of the subpixel color), so the color is either missing or present at a fixed value, the overall color of the pixel not being the required one. In this case is an issue of mismatch of transistor parameters.
The GREEN pixels do not close completely to block the light. Being a progressive issue from one area to another, it's clear that the thin film transistors are progressively mismatched by the process errors. This is process error in the TFT technology (I work in microelectronics). The process masks can get errors (not the case here), or the masks are ok but the etching process is not properly adjusted. In my Xperia the bleeding gets progressive towards the corner, having a starting point like a center from where it spreads. That is because the etching involves chemicals and liquid flow to spread and cleanse those chemicals. My opinion is that the flow in the case of this particular TFT screen model is from the bottom to the upper side, where the upper corners are the bleeding areas for the chemicals and the effectiveness of cleansing is lower, combined with surface tension of the liquids. The transistors get progressively mismatched in parameters (beta factor) and since they all get driven with the same signal, they block the light less than the good ones. Nothing to do about it. Theoretically it might be possible to map out those pixels and provide a corrected voltage for the mismatched transistors (correction table in the GPU DAC ROM), but this is like tooth extraction through the ass hole (or replacing the spark plugs through the exhaust pipe). It's simpler to just get the ****ing screen right. Sorry guys, we are out of luck here. It seems the 800x480 3inch TFT's are not yet top quality, or at least the ones used by SE. I'm really frustrated that the manufacturer used a cheaper screen in a 600-800$ product. This is how a company can loose customers and get the image crumpled.

Slight screen flicker?

I have a nook color, I was wondering if anyone notices a very slight screen flicker like a low refresh rate? Most people would not notice. It doesn't bother me much but I wanted to see if its normal. I notice it most on a dark grey background at 50 percent or lower brightness.

Yes! finally someone that notices it! I have been posting this on other forums. I notice it too on dark backgrounds with about 20-40% brightness, Not sure if it can ever be fixed with an update, but it is sometimes annoying, although not highly noticeable.
I have worked with computer enough that I can tell the refresh rate of a crt just by looking at it. If its normal I am not to worried I justed wanted to know if it was defective because ill switch it out before I root it.
Sent from my HTC Vision using Tapatalk
I get the same thing, very noticeable when you are changing the brightness setting. I use the lowest brightness to read an eBook, and I can really notice the flicker when I lower the brightness, but I can notice it when I get back to the reading screen.
I see it on darker images...its so subtle I ignore it.
Sent from my NOOKcolor using Tapatalk
I still have mine stock... but I see it as well.
Anyone that has loaded any other apps notice it in those apps? i.e. does it flicker noticably in Angry Birds? or other apps?
thanks.

I wonder if it being an IPS screen has anything to do with it. It doesnt bother me to much but causes more eye strain than reading from my htc g2. You would think they would make sure an ebook reader doesnt flicker. oh well i can deal with it.

It's not the screen, per se, but the LED's that are lighting it up. From what I've read, LED's can't vary output with respect to voltage (they're not dimmable), so you have to pulse them very fast to change the output. I assume that the lower the "level" the more the LED is off vs. on, hence the flicker.
Dang I can't post links yet...
Go to Wikipedia, and look for :
/wiki/Backlight#Flicker_due_to_backlight_dimming
I'm pretty sensitive to this, but haven't noticed it on my iPad, but apparently it does it as well. I was wondering why the stock lowest brightness levels were so friggin' bright - probably at the threshold of flicker. You can dim more in a browser or ebook app, which is where I see reports of flicker.

While you can dim an LED by limiting the current (either via inline resistors or with constant current drivers), you can only do so to a degree. Below a certain current, they will simply not light even though the current goes through the LED. On high performance LED's this is still at a pretty bright level. So instead you use PWM (Pulse Width Modulation) and vary the duty cycle to brighten and dim the LED. As the PWM is at a fixed frequency, with more or less of the cycle being lit or unlit, once the unlit portion becomes substantially longer than the Lit part, you can detect the "Flicker" if you are sensitive to it. This is usually particularly noticeable in the "corner of the eye" if you pan you vision across the area and the device gets paned across you field of vision.
This is done on all the new LED tail lights on cars as well and I hate seeing them at night, when they are almost making me nauseous from the flicker.
Good info thanks. Makes sense but wonder why I don't notice on my led backlit netbook. Guess every screen is different.
yea I really wish there was an update to fix this, but i guess it's just the screen, funny how I have never noticed this on any LCD screen I have ever had from computer to TV
three nook colors - my experience with flicker
My first nookColor had screen flicker, also a mind of its own with phantom taps. Nook #2. Did not have noticeable screen flicker but did have a handful of stuck pixels. Took it back and picked up #3. No stuck pixels, but I've got screen flicker on dark colors. Find it strange that nook #2 didn't have te problem with the flicker. I don't like the flicker at all but think it may be timento live with it.

Has any one returned a flikering nook color and gotten a better one in return?
Hello, I am having a similar problem with angry birds. My screen sometimes will flash different colors and today the screen stayed completely red for 2 or 3 seconds while playing the game. But other than that I love the rooted nook color. Maybe the graphics chip is not powerful enough for this game.
Firmware update
What you described with angry birds is not the problem I am having. Mine is screen flicker. My eye can basically detect the refresh rate with low brightness or in darker colors.
Tried to change it out. Would say that Best Buy is much easier to exchange things at than Barnes & Noble. Eventually they switched mine out and the new one had a dead pixel. They then let me open two more in store in the store all had dead pixels, so did their display model. All presented in the lower right hand corner of the screen. Would be covered up by the black menu bar normally, but visible when the black menu bar goes away.
Anyway I kept my flickering nook, and talked to someone at Barnes and Noble tech support on the phone. He told me the dead pixels were new to him, but they knew about screen flicker issues. He said they would be releasing a firmware update to address this and other problems very soon.
Just wanted to note that none of these nook colors were rooted.
Yes, same here, I have that on my Witstech A81 (resistive screen) too, more noticeable when the battery level drops. Never noticed this problem on my iPhones or iPad though...can't be Android related can it?

Thanks. I can see the flicker too on gray screens. I have no other issues though (minus a tiny, tiny bit of give on the bottom bezel). I'll wait and hope it gets fixed in an update. I don't have a lot of time to keep exchanging a good unit.
If it is a known issue and a firmware fix is planed, then I am content with my rooted nook. Thanks for this thread.
I took mine back to B&N today to see if replacing it would fix it. Both store displays didn't have any flicker.
They opened two different nooks and they did the same flickering thing.
So I called Nook technical support. He put me on hold for about 5 minutes. He said he checked about 5 nooks and they all flickered. But he hadn't noticed it before.
So, he will put a ticket into the development team to have it looked at.
So, another confirmation that Nook tech support is aware and looking into it.
My first Nook did not display this behavior. I returned it due to creaking issues, and the replacement did display screen flicker.
I'm hoping it's a firmware issue and not a hardware one!
Currently not a big deal though...

Does anyone have weird vertical and horizontal lines on the screen?

I just noted (pardon the pun) that there are lines vertical ans horizontal lines when displaying white. This is my second phone. I went back to cpw and changed this one has similar horizontal lines. Its very very very faint, but I can see it. Im not sure why, it is because of the AMOLED screen, how it works?
Very annoyed. what can i do? every phone CPW has cant be faulty?

I've only had mine a day but cant see any lines like you've mentioned... maybe a bad batch they got in? Maybe something to do with the S-pen's digitizer screen, i assume that will have some form of grid to it
AMOLED seems to have weaknesses at low brightness levels.
Some have seen very faint lines .
Also on minimum brightness some reported a faint changing of the hue of the display.
The screen is also very bright (whites) on min brightness.
If you display a greyscale step pattern black is absolute black but
others that should be near black are too bright.
http://www.execulink.com/~impact/docs/utils/StepGray16G.jpg
I think its just the AMOLED tech but check the display thread too.
In normal use the screen is amazing,
all technologies seem to have good and weak points if you look for them.
You are not the only one with this problem. I'm on my third galaxy note now... The first one had dead pixels and the right side was darker than the left side. The second one had much more dark horizontal and vertical lines and smudges. The third one at first had very faint lines and smudges, but it is becoming more visible now. There are several threads about this issue on this forum.. My guess is that these problems are pretty widespread (more or less visible on some gnotes) and that there were some bad batches or that the Amoled technology is the problem. Would love to hear the reason to these issues from Samsung.
No lines on mine. White is white and everything shows up excellent.

If you disable the automatic light control and just snap the backlight up from 0% to anything above, you will not see any grayish things in video on the Note. I don't have this problem, but I've heard that some people have had to do this to solve this issue.
I don't have any bandings or strange lines anywhere on the screen. It looks as good as my Galaxy S II and Galaxy Tab. I haven't seen anything out of the ordinary (considering the limitations of the AMOLED screen).
There have been concerns about the lines on the white though. I don't have any of those on mine, but it seems some screens show up this fault. I don't know how to solve this issue and would recommend returning it as soon as possible.
Using the recommended gray test on the Note didn't show up anything but a solid grey screen on mine, although I've heard much people have dark spots all over. It might be something about where the phone was manufactured, or when.
My Note have never had anything wrong with the screen or anything else. The only problem I've ever had is applications that use 16 bit color instead of the Notes 32 bit. This will make color look strange at times, but it's totally normal.
Note that this isn't something wrong with the hardware, it's merely a software problem that will be solved as soon as ICS is released.

I have yet to see ANYTHING with more then 65k colors, even in the browser.
All i see is some VERY clever dithering very hard to see due to the high resolution.
Coming from the HD2, I'm really disappointed, nothing gained in 3 years (well, more pixels, so harder to see the flaws).
I took 3 picture with a green gradient:
1) 1280width, so basicly 1280 levels of green, but 24bit only shows 255.
2) 255width, so basicly 255 levels of green, 24bit.
3) 64 width, so basicly 64 levels of green, 16bit.
They all look the same to me, in browser and in gallery. I see dither in each of them. This tell me the whole screen is 16/18 bit only.
Maybe the PenTile is playing tricks with me...
Or the grainy screen lets me think its dithered...
i am facing a similar problem..whenever i apply some photo having a lot of black in it as my lock screen image..there seems to be some horizontal gray lines in it..but when i look in the gallery the black is pure black (no horizontal gray lines at all)...is there any problem in the software only ? or is it something regarding the screen?

[Q] Random Dimming and Heavy Greenish Tint Issues?

Hello all. So I LOVE my Samsung Focus S that I purchased shortly after Thanksgiving Day...all except for one problem. My phone seems to dim permanently out of no where and nothing I do will correct it back to it's normal brightness except for restarting the phone. Automatic Brightness is off and the "Auto Display Intensity" in the Extra Settings category is off. Now I don't know if this is something that specific to Windows Phone or Samsung Focus S particularly? I'm going to take a guess and say it's on the Samsung Focus S that exhibits this behavior. I also can't figure out if it's a hardware failure or a software failure. I'm beginning to think it's a specific update that is used to update your "Extra Settings". I don't know at this point. I just want to know if others have this problem.
The 2nd issue is not so much a problem now but a concern. My first Focus S had a VERY HEAVY greenish tint to it that was immediately noticeable at the lightest of viewing angles. To give you an example of how bad it was, my buddy was looking at a picture of oranges he took with his iPhone4, I thought they were lemons from the side. I went to an ATT store near me and noticed the Galaxy S II exhibited this behavior as well but the Focus S on display did not. I quickly concluded it was a defective screen as it was REALLY noticeable. My buddy gave me a call and told me he was at an ATT store across town and noticed it on another Galaxy S II as well. I made the employee take out two brand new Focus S' and chose the best looking one. They both looked identical, although the one on display had an edge over all of them. Thing is, ALL of the ones I've seen have a very slight green/blue tint to them. Is this normal with Super AMOLED Plus? Is this the Gorilla Glass Coating? I love the colors and contrast on this phone but to be honest the brightness and viewing angle leave something to be desired, more-so the viewing angle. Sorry for the long post!
I just looked at some pictures of oranges to test this. They look nice and orange do me. at an angle the entire screen starts to lose its pop. But I would not call it green more so just dimmer. Can't complain with the blacks...if only more sites background was black lol.

Would you mind doing me a favor and looking at different viewing angles on a predominantly white screen? Every phone loses it's composure a bit as the viewing angle is more and more off but I've never seen them turn a different hue. Dim a bit like you said? Yes. I looked online to see if anyone else notices this bluish/greenish tint and many do but more notice it on the AMOLED screen though a few did complain about the Super AMOLED Plus. Thank you!
interresting
Ive been running the focus s since it came out and never noticed this "tint" issue...till today. a simple image of pure white, when viewed from above is fine, but as you change the view angle so does the white begin fade into the bluish haze.
now youre all probably going to hate me but i have a titan too. when i pull the exact same image, it does not fade into blue haze. my suspicion is one of two thoughts: a) the super amoled screen samsung uses has this side effect. b) the glass samsung uses creates this effect.
personally its not a deal breaker for me as i really enjoy the clarity of images and color the samgsung has to offer. that said, the titans inability to go true black are more noticable than a slightly bluish white. but thats purely personal prefence.
FWIW, ive tested red, green, and blue matching images. the only difference i see between the two is a decreased viewing angle on the thc in all aspects. screen display differences is the likely cause.
I can see the blue/green from those angles on white screens
kinda ugly actually
still a few days left to return and get the titan....

It's good to see you have a Titan. The Titan is a pretty nice phone. Viewing angles seem quite good and the whites are SUPER bright. It's just the colors and blacks that suffer. Nice to know you can compare them though.

Hey Alright, I'm not crazy. Heh. I'm going to run to a couple of more ATT stores and see what their display units look like. My buddy just got a GSII and he says he doesn't see it, so I'm going to investigate it as well.
BTW, I spoke to someone at Samsung online and he seemed to think it was "normal" and was caused by a Super AMOLED Plus characteristic. Unfortunately I didn't believe a lick he was telling me.
I'm off to find the perfect display! Wish me luck.
i went back to the store
they want to charge me $35 to restock what I have ^^ - and cant seemed to be talked out of it....
the display Focus S had the same exact issues
as does the GSII/SkyRocket from what I could tell
the Titan's whites make the Focus S whites looks blue - but the Focus S blacks look the Titans blacks look grey
and the color palettes are so radically different - for themes the green on the Titan looks like the lime on the Focus S, and the Titan has nothing that can compare to the green on the Focus S - its ridiculous the difference in the saturation and vividness - I can see what people say about the Titan producing more realistic images - but at the end of the day for most things the Focus S is just better looking, who cares if its accurate?
i imagine using the Titan for a while you would get used to it, but side by side it looks paltry in comparison
to be honest the iPhone display looked pretty good! - just too damned small after using a 4"+ sized display - I could never use something that small after using what I have
So I went to ABT Electronics today and looked at their Focus S. It's funny, all of these places, including the Apple store choose the most PERFECT displays they can find in their inventory to show to the public, when in reality your results can vary greatly. For example, the Focus S at ABT had a whiter/bluer screen than mine in terms of whites. It wasn't a huge difference but it was noticeable. Now I want a new whiter screen. My screen seemed buttery compared to the one I saw. We'll see how successful I am. I know I may sound picky but if I'm going to keep this phone for the next 2 years, I want it to look the way I want it.
I also checked out others with the same 4.3" Super AMOLED Plus and I didn't really see much of a green tint to them. In fact one looked yellowish directly and turned whitish on the side. Weird.
OLEd is still a newer technology, compared to LCD - guess there are still some kinks to work out
Yeah, a problem with AMOLED is a slight bluish hint but I don't believe the screen is a PenTile one.
The dimming has been a bit aggressive, I just usually cover the proximity sensor with my hand and let it work again.
Has anyone noticed a flicker (then on) when you unlock the Focus S screen? Sometimes the screen instantly brings up the lock screen sometimes a second after the flicker.
Alright guys. Back to one of the original topics of the Focus S randomly dimming? I think I figured it out. My phone is over heating and the phone is dimming to try and cool it down. No error messages of overheating or anything. I noticed it today when I was playing games on my phone while charging. My phone was pretty warm. Now up until this point, my phone had not dimmed randomly for a week or so, but this morning? BOOM. Dimmed on me. So it hit me. Screen Dimming + Warm Phone = Overheating. I put the phone down on the cold floor to cool down for 10 minutes. Turn the screen back on and guess what? Original Brightness is back.
Either I exchange my phone again or return it all together. I'm in a bind because I can't get the HTC Titan for the same price I got the Focus S for (Free with No Activation).

I have not noticed this at all.
i am in the same boat
almost potentially worthwhile holding out for a Nokia set (perhaps the 900/850)
i actually think I will keep the Focus S to be honest with you
in a year or a year and a half, call up Att and see what they will work for me if I really want to - I have heard lots of success stories about calling them up and getting very discounted phones deals
after revisiting the store - the titan screen looks like **** (IMO except for the whites) compared to the Focus S - and its just too damned big - the Focus S IMO is the perfect size
and all the Android GUI overlays suck ass - so no way I get a droid - and I will certainly not pay $100 for a year old iPhone.
**this fixed mine** random dimming and tinting
Don't throw anything because I just skimmed over the thread before I am responding. I have the Focus S and had that problem. I corrected it by going to "settings>extra settings" and turning off the "Auto Display Intensity" to make it stop adjusting. Unfortunately, that setting defaults to "On" every time the device is restarted. So you have to remember to turn it off. Maybe everybody thought of this, already, and your device does this, anyway, but mine is perfect with this setting off. So, I hope this helps!

I had to use the option in the "Brightness" page under Settings. The option on the Extra Settings page applies only when it is set to a white background.
Hopefully a future update will address this and improve the auto dimming. For now, though, it's set to bright all the time.
U only need to press the power button to let the phone go to sleep, then press power button again and almost immediately the custom brightness u set will be back.

Well the dimming issue hasn't happened to me in quite a while now. I decided to keep the phone. The fact that the display wasn't perfect wasn't enough to make me want to return the phone, especially since I got it for free with no activation fee on a 2 year contract. In the meanwhile, I'm just enjoying it. Funny though, Now that I've got a 4.3" screen, I want MORE. Bring on the 4.7"!

After an Inspire and Focus S, I find the 4.7" display of my Titan too large to easily type in.

I honestly only find it more difficult in landscape mode. Portrait mode is awesome though. I can't stop hitting the "a" button when trying to turn on caps lock. It's really annoying.

Having had 3 Samsung Amoled phones (Galaxy S2, Skyrocket, Focus S) and a SAMOLED (Galaxy Note) I will say that Samsung doesn't display true whites, it's always blueish. As far as the dimming, Go to "Settings" > Exta Settings > Use Auto Display (Turn it off, however; it seems to enable itself after changing the theme from light to dark or vice versa, as well as after a reboot.)

I believe all the phones you had, had a SAMOLED + display no? Also, I checked to see if changing the theme from light to dark turns the Auto Display feature back on and for me it does not. As for my dimming issue, it only seems to happen when the phone is plugged in and the battery is a bit warm.
Overall, I like this phone but I also don't. The display is quite delicious really. I've had it on half brightness for a few days now just to see how it looks to me and today I finally put it back to full brightness and the colors really are gorgeous. It's not perfect but I've learned to look past it I guess. Thank you for the reply.

display banding vertical lines

Hey guys,
This thread is not about the camera taking photos with banding lines, instead about the actual display.
Does anyone have vertical banding lines most notorious when displaying a full grey screen in low brightness.
I've read the verge review and seems to have some banding as well, anyone as well? Thinking about replacing it for a third time.

Yes, I rarely get this issue. I captured a screen shot one day just in case, not sure how well it shows up, but look in the middle lower portion of the screen. Almost like a clock hand pointing at 6 o'clock.

Nevermind, it does not really show up in that pic. Sorry. But yes, I experiencing this issue. Mainly when I am in the settings menu, I think it based on the colors in there. I do not ever see it on my home screen or apps...at least my eye cannot perceive it.

You can't take a screenshot to see the problem. Its a hardware issue therefore you can only use an externeal photo of the screen. Check on grey full color screen. I think I will not replace it, I may risk on another issue..

Yeah, I had not planned on replacing mine either. I so infrequently see it, and even when I do, it really does not impact anything. I was not aware it was a hardware issue, seems there could be a bug fix for problem then.

I've been investigating and the problems seems to be just like the galaxy nexus screen.

Thanks for the link.
Its funny cause the band shows up in the screen shot on my phone, but probably because the conditions are right, not cause its actually in the pic.
Vertical lines are something you should replace your phone for. Horizontal lines like in the screenshot is just the banding of the colors and happens on every single stock android phone because it's apart of the software

Could u check through a full grey background whether ur greyd are fully consistente? I mean there no faint lines whatsoever. Perhaps ur phone is the same as mine and u have not realized it given that it seems to be fairly normal with amoled displays
I was just about to post about this very issue. I created a quick image to show everyone what the issue is. The lines are not as drastic as I made them look, but it should give you the idea of what it looks like on the screen.

No. That is not the issue we are speaking about. The issue we are referring to is VERTICAL and only appears on greyish/black screens, like the settings screen. The horizontal lines are normal for this phone.

Precisely. You can't really use self screenshots to see this problem I'm talking about. Its about the amoled itself having these vertical banding lines(canvas-like strokes). Open Facebook and tap the search button and tap on the search bar without actually writing any name. Tap down the keyboard. For me the deep blue background has the most prominent banding lines for me. I have one week to think whether I should replace it. If everybody actually have these lines and NOT a solid color on full greys or deep blue I won't replace it.
PS. TheVerge moto x review says that it also have some banding lines on grays. I'd be great if you guys could check ur screens like I just explained. Hope I explain it well
Damn amoled!
Someone with the problem should post a sample pic/screen shot so others can download it and attempt to see the problem.
Just download a color test app that makes ur whole screen of a determined color. Put it on grey and check whether ur whole Grey screen doesn't have any vertical line banding. In case it doesn't have any of these lines, please let me know.
If it does have banding, take a screenshot and see it on ur computer monitor and see how the Grey should be displayed(full solid grey without lines)
I don't care enough to install an app, checking out a screen shot is quick and easy.
Took a photo with my tablet. These are the lines im talking about.
Also use the screenshot so u can check whether u have the same problem.
With the screen shot downloaded and displayed on my Moto X I can detect no banding of any kind. I tried it in dim and bright light. Screen brightness is set to auto so it did adjust with ambient light. Maybe I would see it if I manually cranked brightness to max.

Thank you, so my case is a defect, a third replacement will happen I guess. Great phone nevertheless.
It is possible it is something that was fixed going from 4.2.2 to 4.4.x, seems unlikely though. I notice you are on 4.2.2. I am on 4.4.2.
Impossible, my issue is definetively not software related but hardware related. When I see this screen shot on an LCD based device like my PC monitor, no banding is present. After all the pointless investigation this issue is sometimes present on amoled devices like the galaxy nexus.
