Develop Bugs

Three strikes and out.. :(

I have been through three separate Galaxy Nexus handsets and they all had issues.. mainly screen related!
1st handset - got it on launch day UK.. vertical grey lines on screen and volume bug.. exchanged it..
2nd handset - last week.. horizontal grey lines on screen and paint like blobs all over the screen in lower brightness levels.. exchanged it..
3rd handset - today.. horizontal white band across screen.. and vertical colour gradient down the screen.. returned!
I really like ICS and wanted to like the Galaxy Nexus.. I am really disapointed to have waited months for this phone to be let down by poor quality control..
I have decided I will not get another Galaxy Nexus (or Samsung phone - past experience)..
Eagerly waiting for HTC's interpretation of ICS.. meantime.. I sold my HTC Desire (big mistake)..
Wanted to thank everyone here who posted a lot of useful information..

Could be worse... you could be in the US and not even be able to purchase it yet.

Too bad.. i Love this phone... its superd.

Does this issue have something to do with the super amoled display? Have people heard of this in earlier phones ?

That's harsh but I've not noticed anything wrong with my handset - perhaps my eyes just don't notice these sorts of things (or I don't seem them as an issue). I'm sure I'd notice white lines though!

there is known issue with the display when its on low brightness. it goes away when its at high brightness.
if you can't live with that, i am sorry for you. you are missing out yet another pure google experience device.

It's hard to say w/o actually seeing them, but the "vertical grey lines" may have been perfectly normal. From what I've read, there's some level of streaking that normally occurs in these types of displays. On mine, when I have the brightness all the way down and am on a white screen, you can see something that might be described as "vertical grey lines."

A lot of Nexus Galaxy's I've seen have this screen anomaly, which is the vertical streak(s) going down the phone. This is only on white/gray backgrounds, as the screen is absolutely fine with other colors. The issue can be resolved by turning off the automatic brightness and manually adjusting the screen to at and/or above 30% brightness. Or you can flash one of the auto-brightness mods to turn up the default brightness.

My gray lines are horizontal and quite clear on a lighter grey screen.

So sad to hear. I just got my phone and absolutely love it

You shouldn't have to do anything to get a perfect screen on a phone that costs this much.

From what I understand, it's an inherent characteristic of the type of display. If it bothers someone that much, buy a phone w/ a different display.

Hey guys I just saw this and thought I would Give my experience...
I myself got a Galaxy S2 a month back barely and noticed it has the same horizontal lines... about 2 horizontal ones and one diagonal one... along with some blotches... this is a manufacturing fault due to terrible quality control which has started after the super amoled plus screens and sadly and surprisingly seems to have carried on to the amoled HD ones too... never any such issues with the super amoled on the galaxy S including tthe one I owned...
Since it's a manufacturing defect the phone will be replaced generally but unfortunately in my region there is no official Samsung dealer for the S2, I had to live with my purchase...
Again as people have already mentioned you can only see them on the lowest brightness setting or if you are only looking at a dark screen... sometimes can see the lines on grey but depends on other surrounding colours...
I know I'm not happy about iit since it was so frikking expensive, but its still something which guess I can live with... doesn't really make the phone any less amazing...
Would have loved to try the nexus... but just couldn't get myself to go for the missing features...

feel your pain m8 , ive had like 4 sII returned for same kinda issues sensation xe that twice got dust under screen. And now well first phone transparant line annoying as hell second crazy colour banding like you never seen try searching "crazy colour banding" my third arrived with broken screen so awaiting 4th i love this phone but samsung qq is awfull. I can appreciate people say its down to the tech / characteristic but if thats the case why do the reviewers never get one of these handsets .... hmm wait probably becouse they got a cherry picked one.
Anyway if it is a characteristic they could at least put something in the docs they include with phone so the consumer is aware. Or raise the parameters of the screens they pass thru in manufacturing. I know its a different situation but its not like you would except a tv or laptop with these issues so why do we have to accept it with out phones which quite frankly these days can cost more then a laptop or tv.

you do know there are version of Samsung phones with sLCD instead of SAMOLED displays, eh?
if the display is your gripe, then just waint for the SLCD versions of the same phone
like the SGS2 for example or the next version of Galaxy Nexus i9253 with SLCD

I have a horizontal line on my screen. I might be able to post some photos of it later. Adjusting the brightness has no effect.
Sadly getting an exchange. Really enjoying the phone so far.

I have the gsm GN in US. I have also noticed that at lowest brightness level screen on my phone has a darker red/greyish tint from the top of screen towards the center. But I am not returning it. I have seen similar issues with my SGS2 that I exchanged. However my retired Captivate had a perfect screen. I guess it has to do with SAMOLED displays.
Sent from my Galaxy Nexus using XDA App

Your first phone had nothing wrong with it. The grey lines are part of the Super AMOLED display. Any Super AMOLED screen will behave that way, apparently. And it's really only apparent on low brightness. I turned mine off auto and set it to about halfway and it looks great now. Can't even notice it.
As for the volume bug, that's a software issue and was fixed with the latest OTA update...

Screen defects?

After a few hours of playing with the VZW Nexus, I noticed a thin, vertical line of pixels that are lighter than the surrounding area. It's really noticeable on white to gray screens.
Has anyone else noticed such a defect on their display? Would VZW exchange it? I probably won't be able to get to a VZW store until the weekend is up, and I'm worried that they will assume the delay means that I caused the issue.

I think that's just an artifact of amoled screens in general. AFAIK, SGS2 had the same issue.

Are you sure? What I have looks more like stuck pixels; a line of pixels that are firing at a consistently higher brightness than the others. I had a Droid Charge before this phone and never had this issue.

The Charge doesn't have the same screen, it was SAMOLED+, the Galaxy Nexus is just SAMOLED.
That said, I'd need a better idea of what you mean, or how you're testing it. But I don't think I see it, and I'm pretty picky about my display.
I am a little disappointed in the odd washed-out look it has, almost like the gamma's too high.
Anyway, Verizon would probably exchange it, but you'd probably need to call in and have them ship you one. Going in-store you'll be fighting with stubborn sales reps who aren't getting a single dime of commission off their time with you.

My first unit had that, my current one doesn't. Try for an exchange, mine is perfect, but took two tries.
Sent from my Galaxy Nexus using XDA App

Is there a way of fixing it, like how you used to be able to fix old tv's with a magnet?

i have the same issue... and i can`t make an exchange because i bought at USA and know i`m in BRAZIL. =/ have some way to correct this problem??
thanks

Judging by the crickets chirping, looks like the only thing you can do is exchange it.

Has anyone had any luck with replacements? I get the vertical/horizontal line issue at lower brightness, but even at higher brightness solid colors look somewhat grainy.

I had a vertical line and some random spots with pixel problems. It wasn't visible during the day, but at night those pixel were darker than all the rest. Got a new phone within a couple of minutes in the store.

To exchange or not exchange, that is the question...

So I purchased the CDMA Galaxy Nexus last week and love it. I'm coming from a Nexus S and while I think the S had a better screen I think the Galaxy's is great nonetheless.
Either way before I purchased it I lurked these threads and saw that a few of you were having screen related issues. So upon buying the phone, I promptly installed a few screen tester apps to check mine.
I found mine to have quite a few imperfections while displaying an all black screen. Blotches and lines to be exact. And so I asked Amazon for a replacement.
The replacement ended up having fewer imperfections than my original one but they were still there. And not only that but it seemed that the colors were more faded on the replacement one too. So now I have the two phones here and don't know what to so.
Should I keep my original one and stop obsessing, should I send the original one back or should I just say screw it and send both back in hopes for a better third unit?

The franco.kernel app has handy color control options, imo thats about the best thing its good for, it eats the hell out of battery and I get random reboots once a day since flashing it.

The nexus s has better screen than the galaxy nexus super AMOLED HD lol u clearly don't know what ur on about the blotches and stuff is normal on a amoled screen if it is displaying black

If it isn't noticeable under normal use, just stop obsessing about it. I've noticed on a flat black or dark grey screen there are a couple bands (nothing major) but I can't ever notice them in normal use. Its just not worth my time.

Totally agree. AMOLED has issues in terms of a few production defects, but nothing major.
If it bothers you in daily use, exchange. If it is only noticeable when you look for it, stop looking

Thanks for the replies guys
Yes, IMO my Nexus S's screen has more vibrant colors than the Galaxy's. But that's not to say that I don't think it's gorgeous still. It may be due to Voodoo colors or who knows. I use the tweaks in Franco's app by the way, and that has made it much better.
My main concern over the blotches is that it could be an indicator of a possible early screen failure. Probably not however, I'll stop obsessing.

Like the other person said, it is normal to see blotches on a full black screens when in a dark room. Some spots are darker on the screen and sometimes you will see lines. Not a big deal to me.
There are some kernels that allow you to change the colors which will give you a great improvement. Like someone mentioned Franco's kernel and also lean kernel.
If you install AOKP and lean kernel you can control the colors right in the settings menu. For Franco's kernel you might have to by his app for that. Not sure you you can change the color's within the Rom.
I also believe CM9 might have color settings built into the Rom with the stock kernel...

If you mean some lines and pixelerror like thingys on black dark screen than I can tell you:
I'm with my 3th GNex now and all had this "errors" but I can't see them on daily usage; just when for example I'm in a completely dark room and brightness is on 0% and then it's kinda hard to see it too...

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.

I have tried this, and under stock, cold and warm I still get a purple tint to my screen at low brightness (from 1-10) above 10 is usually when it stops. Any ideas?

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.

Blue screen when viewed at an angle

Is this normal? I want to know if this is a good reason to send the phone back for repairs.
The phone has a warm, pretty reasonable yellowish tint to it when viewed straight on. This looks like it was designed this way. When switched to a 30 or 45 degree angle, which really isn't that bad, it gets a pretty hefty blue tint.

It's normal. Mine and two other people I know also have this issue. I'm not aware of any fix so I think that's just the way it is.

I also wanted to confirm this. I have a Nexus S and my new Galaxy Nexus side by side and the NS whites are blinding compared to the subdued whites of the GN.
I am concerned as I only have to tilt my GN about 5 degrees or so in order to start to see blue on the sides depending on which direction I tilt it.

This is a common known issue. There is a thread about the "normal and what's not" regarding the display of the phone. Some are more relatively tinted than others, some are less. Depends on whether if it really bothers you or not that it should be replaced. Good luck!

Yeah I saw the thread but in his photos the phone doesn't look tinted at all. I may call Google tomorrow to confirm if it's within their bounds of acceptable build quality/normalcy. Thanks! It's really refreshing to see helpful people in the forums.

Thanks guys for your replies. I'm not that bothered by it so I'll probably just live with it. I otherwise love this phone. Good to know I'm not the only one with it.
