Dirt and lines under screen

I noticed as soon as I turned my Nexus on today that there was a line across the screen that looked like dirt under the display.
It is only noticeable on low brightness but the auto brightness set the phone to minimum when I turned it on so I saw it. I can only also see it on bright backgrounds like the forum - it is not visible on dark backgrounds or the home screens.
Does anyone else have this issue? I will return it soon and get it replaced but I am wondering if this is widespread or I was just unlucky.
Try turning the brightness right down and looking at this page and see if you see any lines/marks under the glass.

I have a line as well but it's quite small so I'm not really bothered.

Few very feint lines here too. Setting phone to fixed second lowest brightness setting and they vanish though.

This issue is on the gs2's too.

if you go to every forum of a phone that launches you will see the same complaint. its a plague

I can also see two faint grey vertical lines on either side of the screen if I have a light (white) background and brightness settings 1-3!
I haven't come across any other issues, I only noticed it after reading this thread and now its in bugging me. But I love the handset.. better than I expected!
Are these lines normal or do I have a duff handset? I have a couple of weeks to change it if necessary but I am also aware of the stock availability due to high demand.
Anyone else in same situation (O2 UK handset)?

I have the same issue on the lowest brightness, but not on the highest. It is also very faintly noticeable on my SGS2 on the lowest brightness. On my Omnia 7 (samoled) it is also very visible on low brightness, I think it is an amoled thing.

Exactly even the iphones with it's tinting issues SGS2 with it's Blotches in the dark
and the glass isn't perfect around the bezel
people just look for this stuff

I don't understood if this lines means defective screen or if all phones will have this lines.

I have the same thing on my Galaxy Nexus. I guess it's just a thing with Super Amoled screens, rather than a defect.

+1 Just as I said in my post above I have 4 amoled screen devices and they all it to some effect. Do not worry, your phone is fine.

could someone please post a picture so i can see what you guys are talking about? i'm curious to see what it looks like since i don't notice this on the samoled screen on my nexus s.

I had that issue with 2 evo screens. I would also get dead pixels or blotches.. Just have to get lucky with one I guess.

why is fine if it seems to have a problem?
do you think that it is normal to have lines on the screen?
can you tell for sure that every phone have that lines?

I have the same thing on minimum brightness. Its best seen by using a white image as wallpaper and having nothing on your far left and far right home screens. I have many vertical lines. When I scroll the home screen all the way over to the left until I see the blue gradient appear, the gradient varies in shades exactly where the lines are.
I noticed it as soon as i first powered on the device, same as the OP, as it was set to minimum brightness but I dont generally notice it any other time. I dont recall having the same problem with my galaxy S2

Why do I like the screen color of my Evo 4g more than the Epic 4g Touch?

I dont understand why these newer screens just look worse in coloration to me. It seems like all these new phones have a blue or green tint to the screens. I went to look at a Epic 4g touch in the store today because I love the form factor but the screen doesnt look as good to me. Is this fixable with some sort of calibration? Or is the hue always there? I want a new phone but I dont know what to do! I like the screen of my old one more!
What say you XDA experts! Looking forward to your responses!

I think you're 100% right. I remember comparing my old G2x screen to the display unit at the sprint store and being quite turned off by it. It even took me a few weeks to get used to the "bluish" color of the Epic... however.. I do so love that deep black. Wow.

Aagghh! So there's just no way to fix it? Seems like the only neutral screen these days is the 4gs

Check out "Screen Adjuster" by Netman in the market. It let's you adjust the RGB values of the screen, as well as the contrast.
Watching videos on the GS2 is very hard on the eyes if there are a lot of dark scenes... Most of the detail gets lost because of the deep black, even with the brightness turned up to 100%. This app lets me crank up the contrast as well so I can actually see detail in dark scenes.
Essential free app, in my opinion. It can be set to autorun at system startup, or you can run it on demand (that's how I use it).

Any way someone could post comparison screen shots? Would be interested to see how neutral one can get it. Also does using that program cause more battery drain?

There's a setting to adjust the colors to make it less saturated. Lighter colors especially white will never be pure white, then again there is no true black on an LCD

So it wont ever look as white as my evo 4g? Agh. I think I'll just wait for a Tegra 3 phone.

Before I used the program, I could watch 2 full-length movies streaming 3G via Netflix and still be at 45-50% battery. After I started using the program, my battery usage didn't seem to change, at least not that I've noticed.

[Q] Does ANYTHING near-black look purple on your gnex at ANY brightness?

Some people are saying that my purple screen issues documented here:
Matt08642 said:
So I am on my second Galaxy Nexus, and I'm on my way to a third tomorrow.
My first one was absolutely awful, with blacks looking bright purple (Phone 1: http://i.imgur.com/2bjUZ.jpg ) and now OTHER elements looking purple (Phone 2: http://i.imgur.com/1EI0V.jpg ). That's not all. My first one was somewhat free of screen banding, but this one is riddled with it in every menu: http://i.imgur.com/j2oxB.jpg
How common are these issues? I'm getting kinda fed up here.

Are nothing more than standard AMOLED behaviour. They are saying that terrible colors like I am experiencing are normal if the phone is dim.
Is this true? Does anyone have ANY color issues at ANY brightness?

Well... I don't have ANY issues at ANY brightness fyi.

Good to know there are some phones out there that look great all the time
I'm not leaving the store tomorrow until I am certain the screen is perfect!

When you look at the phone in the store tomorrow, and you go to settings, don't get scared away by what appears to be "banding" in the background image. It' just a poor quality image google has chosen to use as the background. See?

EDIT: Here's a new picture showing that the screen is still purple http://i.imgur.com/uaRwP.jpg

Wauw that looks bad. I'm currently struggling with a grainy (gray) screen, but looking at other nexuses that seems normal. On light i can however see darker spots and lines on black screens (including boots and black images) but seeing other topics crawled with the same issue I don't put much trust in a device without it...

Oddly enough, neither of my Nexus' have had the grainy screen problem, just this discoloration

I received my 2nd Nexus today after the firsts' volume buttons stopped working. The new one has purple where black used to be, like yours, but doesn't make the experience any worse. However, when I pull the notifications area down on low brightness, the screen dims further - does this happen on yours? It's quite annoying...

Mine is okay. Not perfect but okay. There is still a little bit of purple (not that extreme like uours) but after a few days you barely notice it

on low brightness the notification tray is almost an opaque black

Same here but top bar gets even darker when notifications area is pulled down, even when brightness is set to 0. Whites are a LOT better tho.
Edit: just noticed that when taking photos, the brightness of whats being photographed affects the screens brightness. Also, top half of pages on tapatalk are a lot brighter than the bottom halves, it's strange and quite annoying once you notice it...

Low Brightness w/ purple tine and grainy on whites

New Galaxy Nexus owner with Sprint. Well late last night I dim my screen cause it so freaking bright Noticed a lot of the greys turned purple and the white (stock messaging app) go a lot of grain in it. Looked like I had dust all in the screen. Is this normal? Looked similar to this picture

I play with my phone on minimum brightness all the time and have not noticed this.
It is possible I'm not observant enough though.
Sent from my Galaxy Nexus using XDA

It's normal.
I don't get the purple hues...but I'm using custom color values.
Which have also reduced the grain. But it's still there.
I may be in the minority here...
But I hate this screen tech. It's my only complaint with this phone.
Nav-bar/Status-bar burn-in potential scares the **** out of me. (Although I don't have any yet...I have to assume it's because I'm so compulsive about hiding the nav bar and using apps that remove the status bar.) And the screen looks like complete crap when it's dimmed.
I mean, it looks GREAT at 30%+ brightness...but browsing in bed and such (low brightness scenarios) always makes me cringe a bit.

I currently have my old fascinate and nexus on hands.
I need to say that Samsung pretty much dropped the ball... :-(
Fascinate screen is so much better looking, though partially because custom ICS rom, which I guess incorporates voodoo tweaks.
I will happily wait while GN ICS gets to that state, but I afraid that it is hardware/ manufacturing process issue and I doubt if anybody will be able to fix it grammatically. Please correct me if I'm wrong. I heard something about gradient fix, but do not completely understand what was fixed and how.
My phone has a slight vertical tint on the right side. I pensive it as pink vertical stripe, followed by green one. Not extremely saturated, but noticeable at any brightness level. I've stopped by Verizon store to see if other phones have it. Out of two checked phones one had noticeable green stripe, another was OK to my eyes.
I got a deal on wirefly and now I'm kind of on the verge - exchange or not. I afraid to get one which will be even worse.

Well I just went back to Sprint and explain it to them. Well since the GN is new that Sprint has no tickets for the purple Screen. So the asshole tells me that it is a software issue and that the next ics update will fix the purpleish colors. I was like WTF it is a hardware issue hahah. I do thank you guys for responding. cant wait to get some Sprint roms avaialble. What do you guys think software issue?

No. its a hardware issue. My GSM doesn't have the purple tint at all. My fiance's first Verizon GNex was the same. One day it died and they sent her a new one and it's screen was very purple tinted. She sent it back and got a new one which didn't have the tint at all.
I would return it.

Thats exactly what I told them and they said to wait for an update. this pisses me off cause they wont let me exchange it at all.

i dont know if its hardware or software but you can try this. its supercurio's display expert and might help. it did get rid of most of the purple for me, still can see it with certain grays. as for the grainy white, my first galaxy nexus had that problem at low light too. its almost like a transparent cheese cloth over the screen and some lines running down it. i returned that one.
just keep trying with a different rep. the first one i talked to pretended not to see anything wrong with my phone so i talked to the manager and got the exchange after about 15mins. they were still very hesitant. try to call their call center first i find their call center reps are usually more understanding.

I have a purple tint, but only at brightness levels going below 15 (setting custom brightness with aokp), but the default brightness was at 19 so I never noticed until I started to mess with the settings. I think its normal, or at least I hope it is. Well now I want to ask, is it normal to have purple tints at really low brightness?

Three strikes and I am out. This is my first amoled screen so I am not really sure if it is supposed to be like it. I will try that apk and see if that works. Thanks buddy. I am honestly afraid to get another one and then it is fully a retarded phone so I will stick with it.

I'm unable to use that apk. Error says "There is a problem parsing the package"
Do you have link to thread or other location, please?

i dont know the exact post but its in this thread towards the end.
forgot to mention that you have to use a kernel that supports color calibration, im using franco's.

Let me know how it goes, cuz I am rooted and running Franco kernel and still getting the purple tint.

the purple tint is still there for me too but the cold setting in that app helped a lot.

It is a hardware issue even though some software tweaks will help a little bit. My GSM gnex has this issue while my friend's gnex does not have it at all. I can't exchange mine because it is from Poland and I do not know anybody there. I just set the brightness to 50% and the issue is almost nonexistent. So my advice is to exchange it; try another store or speak to the manager. Good luck.

Ya for some reason for me thought it only happens are really low brightness. How about you?

I tried playing around with color calibration on one of my previous purple Galaxy Nexus phones. Got rid of the purple, but then things started looking too green or something.
Not sure how you can calibrate to fix colors at low brightness levels where purples become a problem and not screw up the colors when you increase the brightness levels. Doesn't seem like this would be a good solution.
I have just kept exchanging my phones. And I hate AMOLED, it's great when you get a good one, but it seems like Samsung can't make very many good ones.

Lol. If you're going below stock's lowest setting the purple graininess is normal. Get a grip people. Its a mobile screen and it has tolerances. If you get purple just lowest stock setting, I would say it is not normal but chances are Samsung will say it is within tolerance. I played with root dim the other day my screen got purple and grainy at 4/255 and below. Slightly grainy at 5/255 and 12/255. 13 and higher it was fine. 15/255 I believe is stock's lowest setting.

How prevalent is black crush?

This is one issue that actually affects my user experience. I'm trying to decide between an RMA and switching to a Pixel 2. If black crush is a universal problem, I'll go with the latter but if it only affects a few devices I'd rather RMA and stick with the P2XL. Chime in, black crush/screen bleed - do you have it?

I have it. Very noticeable. Curious if it is widespread or not, as well.

When is it noticeable??

FYI - the Pixel 2 has it as well.

I seem to be finding mixed messages on this. Some report this is not an issue on the Pixel 2 and only the XL. I only have an n of 1 for each device - my P2XL has it, my wife's P2 does not. Ultimately, this is what I am trying to figure out - how widespread is the issue, do I play the lottery or exchange for something new or just keep my original XL, though I'd certainly miss the camera and active edge.

Low brightness, dark videos and images, basically any near black colors get "crushed" to black. I was watching The Croods on a flight the other day and there is a dark scene near the end of the movie where I couldn't make out what was going on because it was so bad. Any dark area of the screen went completely black and/or black and very pixelated. There are a few test images in a thread on Reddit to see if you have it, I'll see if I can link it.

I found blacks at low brightness to be quite extreme as well, I'm fairly certain this is something that could be recalibrated in software but I doubt that Google will do anything about it

See I don't think it is necessarily the screen as the display has a really high range of greys, so I think it could be fixed to some extent. The bigger problem I have is the ridiculous amount of black smear at low brightness. I never had anything like that on my Nexus 6P, it is dreadful.

Yeah same. I've got a decent unit at normal day usage. Once it gets to lower brightness and night mode is not very nice. The black crush is slot worse with night mode
.but black smear is there with or without.
Wish Google just went with a Samsung panel

Yeah, this is kind of a weird one as it seems to affect both P2s and P2XLs, but not all. Maybe its mostly a software issue but is most pronounced on certain screens for some reason? Idk.

It is difficult. Also do you trade in for another one? But run the risk of getting worse blue tint or grain or uneven whites... I'm going to give it a week, see if I find it a big deal or not. 90 percent of the time I don't notice because the brightness is higher during the day

Wow, so I've got a pretty bad unit...
Black Smear: Even on full brightness and slow scrolling. So bad, it even covers Text to the unreadable (It's complete gone and "hidden" under the Black-layer).
Black Crush: Until 40% noticable on Photos. Mostly in Shadows which are normally grey. They turn to a complete Black which looks awful.
Blue tilt: Starting at a very small angle. Pretty extreme and bad, but the other two are more of a dealbreaker for me.
Currently requesting an RMA after resetting my Device. And be sure to be nice to the Support. They did not manufacturer this Device wahtsoever.

Play with the settings to ur liking.

I don't see anything wrong with blacks or greys during videos or on pictures whether night mode is on or off or brightness is high or low. Can someone post a screenshot or two? I'm curious.
