[Q] Screen Banding and Notification LED ##With solution to notification issue##

I got my Galaxy Nexus yesterday and I love it. There's just a couple of things bugging me and wanted to see if anyone else was having the same problems and of course if anyone knew of any solutions.
1- Screen. The resolution is fantastic but i've noticed some banding in flat colours. It's most noticeable in light and mid greys. There is a strip that runs up the middle of the screen that is noticeably lighter that the rest of the display. This goes away on high screen brightness but is really quite hard to ignore at other times.
2- Notification LED. Why is there no native support for customising this in ICS!? Either I've missed it or Google have missed a trick. I got it working with an app from the market but it only worked while the apple was running in the background, if I dismissed the apple from the new task switcher... No more custom notification lights.
Anybody else having these issues?

To get the most out of your multicoloured LED you can use the Lightflow app which is available free from the market, to get this working properly on the Galaxy Nexus enable "Run in Foreground" in the general settings menu.
Thanks to jabok for spotting this setting.

Sorry to bump but I'd really like the opinion of a few other Galaxy Nexus owners, especially about the screen.
I love this phone but I am considering taking it back because of the banding on the screen, it's not noticeable until there is a flat grey in an app and then it's quite visible as a lighter band up the centre of the screen.
Is this a fault or is it to be expected on sAMOLED screens? I've only had LCD before.

Does it look anything like this or something different? http://forum.xda-developers.com/showthread.php?t=1320942
Either way there are issues with SAMOLED+ screens, there are people with the Galaxy S II and Droid Razr with screen issues too.

as far as I know, it is a common trait with Super AMOLED screens - had the same issue with my Nexus S, and with my friend's phones that have Super AMOLED screens.
The banding disappears if you have the screen at a higher brightness, so it does seem to be an issue inherent with changing the brightness/colour temp of the screen.
Also, AMOLED screens are susceptible to screen burn, which is why if you leave the screen on some white text on a black background, if you then switch to a screen with mostly grey elements you'll see a ghosted image of that text.

Seeing similar on my screen but it's not really noticeable unless the phone is on auto brightness or the lowest manual setting.
From reading other threads, sounds like the GSII has a similar problem. Looks like some people have been through a few phones before getting a "band free" unit.
You could try taking it back to a (willing) store for a swap - given the current stock levels you may have a few issues though and you may not get a unit without the banding anyway.
In terms of notification LED, wait a bit for some better third party apps to arrive. Not many (existing) phones use RGB coloured LED's or similar for notifications (Nexus One and Galaxy Nexus are the only two that quickly spring to mind) so it's possible Google didn't add support because of the limited use. ICS is in it's infancy and there's a lot of development to come (both from Google and third party dev's).

Thanks for your responses!
In some ways it's good to know it's a know issue, and in others it's a bit disappointing.
I've attached an image for you to look at, you think it's worth sending back?

No.

Personally, I'd just live with it - especially given that there's no guarantee you'd get a better model if you swapped it - hell you could end up with a worse screen!

I'm not sure it would be worth the hassle to send it back. This seems to be an issue to some degree in most SAMOLED screens. You might end up with a worse phone.
I seem to recall that many phone screens have artifacts at very low brightness settings.

This is exactly the same problem as I have. On low brightness it is visible but not on normal brightness.
I did have another nexus on order that I was going to compare it with but I decided to get an N9 instead as I don't need 2 nexus phones! I figure I can go try android beam in a phone shop lol
The question about sending it back is a tricky one - it's not visible With normal brightness so how can we be sure the replacement won't have the same problem? We can't.

yep. i have a vague banding when i look very closely.
solution ? keep my eyes more than 3 inches from the screen.
I hate it when people point out things that you have to look very hard at cos you then notice them forever more

can you confirm that with normal brigthness the problem is solved on every screen?

for the LED customisation get Light Flow from the market, works great for setting different colours for all sorts of things.

on auto-brightness i can notice it (if i look very hard) on the calendar app.
pump the brightness up to about 85% and go back to the calendar app and i cant see it ... but now my eyes hurt

i just picked a random setting to prove/disprove the brightness thing. to be honest i REALLY have to look for these bands on auto-brightness .....
just tried 50% (still too bright in my opinion) and i still cant see banding. nor about 40%.
switched back to auto (which must be only about 20%) and they are there is i get really close and squint.
Seriously .... wouldnt let them worry you !

thank you.

I have just completed a 3hr car trip using Google navigation and noticed the banding on auto resolution with it disappearing on bright vivid colours or dark/blacks. Thinking of asking phones4u to check out others for a possible swap.
When the phone was on charge i didn't notice any status light or none flashing when a txt was received. Should there be?

"True" Blacks Smearing/Lagging behind Display Issue

I've notice the screen will smear/lag behind while displaying "true" black (pixels are off) areas of the screen in fast motion (pictures, backgrounds, etc...). I'm sure this is a common problem with this display type as I've read similar things before (purple or black), but wanted to make sure all is well on my expensive new toy. It seems to happen more when the brightness is turned down, but it can also be noticed heavily on gradient backgrounds while scrolling left/right on the home screen. Turning up the brightness does resolve the issue for the most part (you can still see it, but it goes away much quicker), but why is it so apparent on this display versus others (Galaxy S5)? Maybe having many more pixels to flip on and off in the affected area is the cause due to the phone having a 2k display versus the 1080p display of the Galaxy S5. Anyone else experiencing this issue?

I have this issue as well. I have not seen anymore information on this issue anywhere. Have you heard or seen anymore about this?

Yep. I too have the exact same issue. I wonder what the consequences will be when using thw Gear VR with our Note 4... probably weird smushy images I'm guessing

I've had this issue as well. I was on a Plane at night watching Dark Knight Rises. I have auto brightness on so it dims in lower lighting but in that movie there's a lot of dark scenes and you can def see the lag with the pixels during fighting scenes and fast movement.

i am having this issue.
on the european note 4
i have no idea what to do and i dont want to visit service on the holiday season..... :crying:

Mine does this also. Only when the brightness is extremely low. I think it has something to do with the pixels being "lazy" when the brightness is low. It would be a drawback that comes naturally from the benefit we get with OLED.
EDIT: To sum it up, nothing is wrong, it's natural, just turn up your brightness when it is critical to not have the smearing.

Word. I only noticed it in low brightness levels so I'm not worried. At least blacks are actually black, instead of some purple-ish weird color they had back in the first Note.

[Q] Question about ambient screen

Hi, i was thinking of buying either a sony smartwatch 3 or a moto 360. Do all of you guys prefer the 3? Tge thing that has stopped me from buying the watch is the ambient screen. Based on your peraonal usage did you find the yellow tinge that noticeable? Do you have any pictures that you can show me just so I know its not going to be an issue for me. Also ive heard that the smartwatch is good for running? Is this true because thats what im looking for. Withthe ambient screen is there anyway to change the diaplay conditions so that that it is less yellow if I root rhe watch? Thanks for the help

yellow screen?

yes, you really should buy the SW3. I did it, and a friend bough the moto360, and he told me that he had a serious lack of battery, slow watch and so on. The SW3 works perfectly, has a great battery and the ambient mode is really good. On my side, i didn't notice any "Yellow-ish white". Definitely the best watch out there.

See attached picture....I like the ambient best on the Sony SW3 with a white background and black letters/time/text.
The background in ambient looks like one of those old LCDs and is very easy to read from all angles even in an office with less than perfect light conditions.
When you have a black background with white text it does look slightly yellowish, not bad in my opinion.

How did you flip the ambient mode? Typically it's white on black and yours is showing a black on white. Thanks

I created it with Intellicom. You can define the ambient background independently. I also own watchmaker, but unfortunately cannot specify the background for ambient mode there....unless someone tells me how to do that...I contacted the developers but never heard back. Maybe if several SW3 owners raise their voice we get that feature in watchmaker (which otherwise is a great tool).....

Invert it! Getring more white on ambient uses more battery.

Just add a square shape, enlarge it to fill the screen, move it to the bottom, make it whatever color you want* and set it to display when dimmed only. There's your ambient mode background.
*As MickeZzz has pointed out, although you can set the color to whatever you want, it will probably be displayed as one of four shades of gray (white, light gray, dark gray or black) in ambient mode. But the point remains that you can use a white background in ambient mode.

Aren't we talking about two different things here? The transflective screen doesn't require power to be readable in all but the dimmest light; that's true. But it's still not like an e-ink display, which can continue to display an image after power is disconnected. Doesn't every non-black pixel on the screen draw some power, even in ambient mode? Maybe the drain is small enough to be insignificant, but I don't think it's zero.
Please correct me if I'm wrong about this!

No. The Sony one is a transflective LCD. LCD use the least power when displaying white. Black requires LCDs to draw power to change polarity to filter out the backlight...hope that clarifies things.

Summary: long press a thumbnail, then press again and drag. The bottom layer at far left.

I made a simple test in watchmaker to show the difference between bright and dimmed screen. I simply added two pictures in watchmaker and put the display mode to always on the pictures that I used.
In dimmed it seems to only display four different gray colors.
It wasn't possible to make screenshot so I simply used the camera, sorry about the bad screenguard on watch.
I really like the screen outdoor!

I'm not trying to dispute you, but I am trying to grasp this, especially since finding an earlier thread here, in which it's pointed out that the unpowered state of the display is, in fact, black. That would seem to suggest that black uses less power, but I realize it's not necessarily that simple. Do you know of any references that explain this?

I of course could be wrong with respect to the LCD in the SW3, I am only repeating what I have read about LCD a long time ago....
Best is you try for yourself - I have not noticed any significant difference (clearly not a scientific study) and I like the contrast better when the background is white.

I have the same effect in original Youtube app. It is just a bad background gradient in the application. Don´t blame the phone....
When I open Messenger with black background and grey status bar at the top of the app in the same brightness level, there is no greenish effect.

I am also having uniformity issues. Very noticeable, unfortunately. As there are no 512GB Ultras available anyway ATM, O will just have to live with it for the moment. Maybe I get used to it...

mm weird, I see it in every single app with dark grey background, even in settings (w/Dark mode on), the bleeding is a lot bigger from the top right corner.
EDIT: Just checked the messenger app (FB messenger) and background is completely black so most pixels are off except for the letters and gray search bar but bleeding wouldn't be noticeable.

I've just checked it with Gmail since it is also a Google application and you can notice the bleed when the lights in the room are turned on and I try to cover the top of the phone to see it. After turning the lights off, whole app is equally gray so in my opinion it is just an optical illusion. If I recall well the AMOLED displays use some kind of dimming (tinkering with the frequency) in order to reach a lower point of the brightness that is not noticeable for human eye. Probably this can be seen when covering a gray part of Google apps in a room that has another not so bright light source.

I made a picture. It is showing a 5% gray test pic and supposed to be uniform. It is easy to see and I was kind of shocked when instantly noticing it the first time I was using it in the dark. Settings and many parts of the dark one UI are using grays in that range.
Anybody else? If it is rare, it will be worth pushing for an exchange.

I did the same test, I'm attaching a picture of my Note 10+ and the S20 Ultra side by side. Uniformity seems a lot better on the note 10+, however on white background the Note 10+ turns more red when I slightly tilt it while the S20 Ultra seems to shift colors a lot less and still white overall.
Still not sure if it's worth the hassle to return.

Ok, the fact, that it looks very much like mine can be good and bad ?
Could you please check, if is different at 60Hz? For me, it is clearly different.

Oh wow, you're right! I set it to 60 hz and QHD+ and uniformity on the gray test got noticeable better, still some green on top right corner and around the punch hole but noticeable less. I love reaaally 120 hz during normal use though.

Thanks for confirming, same here. I wonder, if this is something, that can be fixed in software... And if the rumoured 'dynamic refresh raze' update might change things.
Could please note people check their Ultras displays?

Same here with my s20 more visible at 12hz refresh rate with dark theme

Damn it, ok, then I really hope that it is fixable... Weird.
I am using smiled displays since Symbian Nokias, never had one, where I noticed it so much.

I remember all the Mate 20 Pros with LG screen had this issue buy way worse in some cases
https://www.google.com/search?q=mat...JtXpfSDsL9sQXomrbgDQ&rlz=1C1CHBF_enUS731US731
In some cases they were normal during the first days but the problem evolved until the display was unsusable in low light conditions, hope the same won't happen to our phone during the next weeks.

yeah I don`t have this issue I did the screen test in Gmail and download the app that does all the different colors including gray, at the lowest brightness and at other levels of brightness at 120hz its all uniform.

Mine is most noticeable at around 35-40% brightness and with 120 hz but still noticeable with 60 hz while on the note 10+ I can't see any green at all at any level of brightness. I think it's a quality issue and variation of OLED screens but not sure if it would count as "defective". Samsung doesn't do exchanges so it would be a pain to return everything and recorder without the promotions and reservation/pre-order credits. Ugh not sure what to do yet.
EDIT: Btw I tested with gmail and didn't notice the green in the app since it's light gray but as soon as I drop down the notification panel (w/dark mode on) the green is immediately noticeable. It's only with very dark gray that lookd almost black which is what Samsung use for all their apps (settings, calculator, messages, etc.) when dark mode is on. I wish they used true black so pixels were completely off like with facebook messenger.

I am also unsure what to do. I have to say, however, that this is the device that gives me the most uncertainty ever. For this opportunity price I want a good to perfect display. @vwite Don't you think that the dark grays are too bright as well? It wouldn't be so visible otherwhise. I also sent my picture to the 'write the CEO' address and a pledge to be aware of the issue:
https://www.samsung.com/uk/info/contactus/email-the-ceo/ (example: UK)
I will try checking in a store, which will be totally hard because of the light there. Maybe I will just order another one... Or a plus ?

Made another picture 'for the CEO' :silly: and will also attach the source image I showed on screen. To replicate:
- 25% brightness
- Show 5% picture in a dark room
- made picture with an S10+ on full auto

Thanks! Please let me know what they say.

Actually I ordered an S20+ now and will most likely just give the Ultra back in the first 2 weeks. Yes, it is a pain, but I really can not stand the screen as is. I am even putting it in its box before I have the plus and using my S10+ in the meantime - the green tint is driving me a little nuts.
I am having a hard time justifying the thickness and weight for a feature I hardly use (amazing zoom) while having an inferior main camera at the same time (focus issues).

i noticed this issue too on my 20+
it seems to be worse some days less bad other days
it also is very dependable on how much ambient light is around - eg is much more noticeable in dark rooms
and yes is an issue with Samsung dark mode that isn't true black but some dark greyish
other then this - all other colours look amazing = so not sure if the screen itself is defective
I do hope there will be a software update that will fix this or make it less visible

yellowish tint/tone on screen,known issue or?

Well,this frustrates me a lot,I'm just uploading video so you can see and compare to some cheap other chinese phone.
I'm noticing yellow tone all over screen,kinda like there is a night filter on with very low bright nightlight settings.
I increased brightness all the way to 100 % didn't help.
I also removed plastic cover from phone,nothing, still present.
I even switched to Vivid display settings before that and reduced RGB (R channel all the way,G to middle and Blue increased all the way) and set tone color to cooler slider all the way,no difference.
So,since I purchased using phone,is this some software bug/issue or I got faulty screen (maybe some kind of damage from sunburn),or this is just how this display work?
I'm uploading video and will post link soon...
So anyone else having same issue,and what to do,be sure I can not RMA the phone since I purchased it used.
I'm also anxious that the screen might die on me soon.
But this yellow tone frustrates me a lot,colors are not accurate at all because of it.

does it show in safe mode? what happens after reboot, goes away and come back later or...?

Hmm,why would I want to access safe mode,I don't have issues with phone except bad wifi and this issue.Mostly it's noticeable while watching vids (youube),look here if you can see the difference...but maybe it is suppose to be like that.
I set color mode all the way to cool tone and no difference to my eye.

I called a friend on a drink which has N10+ too,then we put 4k Nature video on each of the phones at same time and same screen lightning intensity.
No diference,between them...so now I'm confused totally.
Are my eyes cheating on me,is it possible that there is slight yellow tint (like light night light filter) or something is wrong with my eyes?
Is it possible that maybe screen adapts it self based on ambient light so I'm seeing yellowish tone...who knows,but I do trust my eyes,though picture was the same color accuracy on both phones...
I'm totally confused now...

I have currently 2 note 10+ phones. One which still has the original display while on the 2nd I installed a new display with frame. Comparing both these phones now, the older display - about 1.5 years old with light screen burn on the bottom is more yellow than the new one. The new one is very white compared to the old one. Maybe your display is showing its age?

damn...it was a damn mask/cover with yellow tint over it,not display...how was I stupid.

Some weird posts here, didn't you say you removed the film earlier ?
