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.

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...

[Q] screen Issue(terrible blue tint)

When i tilt my Nexus ever so slighty any direction the entire screen turns blue. Is this an issue that can be fixed with a software update or just a bad screen. Thanks for your help in advance!

Sounds like a bad screen, haven't heard of anyone else having that problem, take it to a Verizon store and show them and they should give you another one.
sent from my new love, the sexy Nexy

I have a similar problem, except that the screen appears to me to have a yellow tint when looking at the screen from head on and only appears normal when I look at it from an angle. I would prefer mine to be like yours, as it sounds like the blue is brighter overall.
Are you using a custom kernel? A couple of them do have more blue than the stock ones.
The screens on these devices do seem to be be extremely variable. I am now on my third GN after having had my original handset replaced twice and each screen has had a different defect. None of them showed colours properly. I have checked with ones in my local store, and they do not seem to be affected, which makes me wonder if this has to do with certain batches. Sadly, my carrier will not allow me to exchange mine for one in the store because I bought it over the phone. I'm now going to try going through Samsung to see if they are able to exchange it for one from a different batch.
With my old Galaxy S, I used Voodoo Control to get the colours just right.
If a similar tool becomes available to calibrate the colour on this screen, I'd be more likely tolerate this problem.

I've got a slight blue tint when I tilt mine as well. Is this normal?

Sounds normal to me if it only shows up when you're tilting the phone and it doesn't stop you from clearly viewing what's on the screen

The blue tint is just what happens with this screen. All the units I have used(including my current one) only do a small section of the screen, not the entire screen. So, if it is going over the majority of the screen then it is a bad unit.

[Q] New Note 3 has discolored corners at high brightness

I just received a new T-Mobile Galaxy Note 3 and I'm wondering if there's a problem with the screen. As you can see in the attached photos, when the brightness is high (about 50% or higher) and the background is white (or other light color), there is significant and noticeable discoloration in all 4 corners of the screen. The second photo also shows that there is an area that is slightly darker (grey color) that persists constantly.
I've read through the forums and don't see any specific mention of this issue with the Note 3, so I'm wondering if anyone has any idea if it's a bad screen, or do all Note 3's display this behavior with high brightness and light backgrounds? If anyone has any thoughts, please let me know. Thanks!

Do you also notice the discoloration when using it with Chrome or the Internet browser? If so, replace it.

is this a NEW one or a refurbished replacement/exchange? seems like the screen is bad. mine doesnt look like that at all. if its a replacement have them send you another one. could be previous water damage
do you have a screen protector on it? maybe its polarized film and causing that effect?

Yes, the discoloration is present in all apps. The seller told me the phone was brand new (not refurbished) and there is no screen protector. Thankfully, he has offered to take it back and give me a refund. Thanks @Limeybastard and @rlee008 for the help!

S4 mini i9195 and true black amoled

Hi,
I'm wondering if the s4 mini has true black screen values when in total darkness. Mine seems to be a faint glowing gray when showing black colors. On my S4 (the big one) black is truly black, my Note 3 had this as well. Now i'm wondering if this is because at one point my s4 mini's screen was replaced, and i got a bad screen, or has samsung used older amoled screens like the one on the S3? What are your screens like? Also, has the VE (i9195i) edition updated the screen? I can only see the issue when in a totally dark room, under normal light i can't detect it. Would like to know, cause i love reading at night

the s4 mini was one of the first to use a s-stripe technology if i remember correctly and that is superior than the pentile on the other devices you have and most other Samsung phones as of late.. that is except for burn in and degrading. The screen on my 9195 had screen burn in within months of owning it and after the first year had a solid yellow tint permanently on it. Oled degrades fast and maybe that what you're finally noticing?

I do not notice a yellow tint, just a faint glow in the dark, as if there is a backlight active.

I have 2 screens here, from I9192 and I9195 and both don't display true black

Ok, thanks for confirming this. Anyone with a i9195i (ve) here? I reckon they probably used the same screens.

I have rebuilt all models, they use the same(ish) screens. the ribbon cables are different but the displays appear to be the same.

Why I'm returning my S20 FE 5G

I have now had my phone for a little less than 3 days, and I've been happy with the speed it' blazingly much faster than my OnePlus 7T pro. It seems that I forgot my most important task when I buy a new phone: Test the screen quality on grey backgrounds.
One the 2nd day I noticed a faint white bar going through the middle of the screen while using spotify, so this morning I tested my trusty grey backgrounds, and one of them in particular had a nice/shocking result. One the left we see my OP7T with perfect color rendition, on the right the S20 FE that shows a brownish mess with lines going all over the place. I'm sorry for the bad quality cause this was taken on an aging Nokia 7 Plus and I couldn't make the picture sharp no matter what, but it gets the point across.
I did my research. I watched all tech youtubers of note reviews/comment on this phone and I thought since this phone is largely based off of the Galaxy A51 I thought they had the production figured out. But nope.
3 years ago this wouldn't have been as much of a problem, but since I use dark mode all over the place now, I just see these lines all the time, and once you see, you cannot unsee.

Multitouch issue. I have tested another one but same problem. Finally flagship with Snapdragon for EU. But sorry the phone is not complete.

omg it's not a problem you can disenable that line .

I use dark mode and low brightness settings indoors, I've not encountered this banding. I know that if you video the screen on low brightness you can see the screen pulsing but that's not a use case I'm going to deal with.
