[Samsung Galaxy Nexus] THS1989:
EDIT:

tldr: Too much Vertical lines on my GN. It's very visible and worse than the graininess.

I know others won't agree with me here but, this is a $650+tax phone.

A phone of this price deserves a perfect screen.

Look at iphone 4 / 4s. Sure the screens are small but there are NO ISSUES WHAT SO EVER. The IPS they use is basically perfect.

Ever since I got my Galaxy Nexus, I have had concerns regarding the screen:

1) It kills too much battery. Battery settings show it killing 50 - 70% of the battery WITH AUTO BRIGHTNESS ON.

2) There are LINES EVERYWHERE. The whole screen is very grainy unless the brightness is very high. But then it's too bright (especially for low light reading) and it will probably kill 80%+ of the battery....

3) Pentile matrix. Sorry to say but it's very noticeable. This is especially true for text that is white or red.

Cycle through the colors and notice, Green is the only true 720p. The red/blue look terrible and you can see the sub pixels (because there are only half as many of each compared to green)

Overall, it's a great screen. I can live with the high battery drain (large screen). I can also live with the pentile (high resolution, excellent blacks).

However, the lines / grainy textures everywhere is just unacceptable. I could even live with the grainy texture but there are a few vertical lines that are VERY noticeable.

Should I get mine exchanged ?? I'm just afraid that the replacement may be worse....
[Samsung Galaxy Nexus] nosympathy:
they are all kinda like this. Some worse than others. I just don't mind it as much. What is killing me is the camera...it is so bad...
[Samsung Galaxy Nexus] DirgeExtinction:
Honestly, I don't see the graininess,even with this antiglare screen protector I have on.
[Samsung Galaxy Nexus] dspcap:
Just about every new phone has the same two complaints... Battery and screen. Not that you don't have a valid complaint, I've noticed it too. I just don't think you are going to find that perfect balance in a phone.
[Samsung Galaxy Nexus] THS1989:
Don't think the screen protector has anything to do with it.

I'm using the SGP oleophobic atm.

What really bothers me is the Vertical lines...

Try this. Set your background as a solid dark grey color. I guarantee you will see the imperfections.
[Samsung Galaxy Nexus] devadvance:
The definition of 720p is based on pixel arrangement, NOT subpixel arrangement. it is a 1280x720 screen. By your definition, a 720p/1080p screen is only true if it is an RGB subpixel arrangement. So you would also say that the Sharp Aquos Quattron TVs that have a yellow subpixel are more than 1080p.

If you expected the equivalent of a current generation plasma screen shrunk down to a 4.65" screen in a phone, that's just unreasonable. Its the first iteration of this tech. Lines and grainy screens are AMOLED's version of lasting burn-in and high power consumption on plasma.

Also, everyone references the iPhone. Why? The colors are inaccurate and undersaturated, and the contrast is too high. It is NOT a calibrated IPS panel. Name-dropping IPS technology means nothing.
[Samsung Galaxy Nexus] reverepats:
Absolutely perfect. Couldn't have said it betta
[Samsung Galaxy Nexus] Andrmgic:
They are all like that.. it's a flaw of the pentile matrix that they used to build the screen.

auto-brightness makes it worse.

What's the point in setting up a scenario to expose the flaws that exist in every (gnex) screen?

Most people's use-cases won't involve that scenario and they'll be able to enjoy the screen without a problem except for battery life, but battery life is always going to be a problem for a display larger than 4".

In my day to day use of looking at things other than dark gray backgrounds and solid color fields, the screen looks fantastic and has one of the highest pixel densities of any phone display out there. (Nitro HD, Rezound, LG's 720p screen phone and iPhone 4/4S have slightly higher pixel densities.. but they're all a cut above most other phones available)
[Samsung Galaxy Nexus] jonny_rubber:
ok the wife and i upgraded at the same time...........i chose the GN she chose the iphone 4s.

and honestly i would be gutted if i had chosen the 4s !!! ive worked a lot with the sg2 and for me the screen is too 'in your face' colours are vivid...the GN screen has a great balance.........and well going from the from the GN to the 4s ..........jeez the 4s is tiny :-)
[Samsung Galaxy Nexus] SomeGuyDude:
That first point drives me crazy. It's a percentage of battery use, do you get that? It means that if the phone uses almost no power except a little when the screen is on, then the display will be using most of the battery.

What you WANT is that. The worst is when cell standby eats up all the battery. That means it's draining just sitting on the table.
[Samsung Galaxy Nexus] wendellc:
Next time get a iPhone 4s cause it has a perfect screen, u will then have no buyers remorse.

[Samsung Galaxy Nexus] P-bot:
People have been *****ing and complaining about this phone not coming out fast enough for months now. Now that it's out people are logging in here to ***** about it not being perfect.

All I can say is that some people are creating a lot of needless suffering for themselves. At least keep it to yourself if you are going to go through life with that kind of an attitude.

If 14 year old me could have seen this phone in 1991 his head would have exploded.
[Samsung Galaxy Nexus] AdamNJ77:
I'm not an expert, but I just sold my Bionic and got the G. Nexus. The pentile on the Bionic drove me NUTS, but I LOVE this screen. I don't see ANY screen door effect, and I have loaded a few HD Videos on it and watching them is GORGEOUS. The colors are amazing and blacks are better then my 55" Samsung LED with an 8 million:1 contrast ratio. My roommate has the iPhone 4, and his draw dropped at this screen, and we held it right next to the iPhone 4. Only complaint is video recording is shaky, glad they are adding video stabilization in 4.0.3. OH, and I looked at my battery usage and the display is 68%. I bought the 2100mAh battery (for 25 bux, and barely any size change why not) and am getting a good 8-9 hours with a lot of use out of it which is about what I got on my Bionic with the 2760mAh extended battery. So maybe the screen is just by far, the most power intensive component, hence the high percentage of battery use. Anyway, this phone, like all others, could use improvements in some areas, but I absolutely LOVE it. And am SO GLAD to be rid of my Bionic (GOOD RIDDANCE) ;)
[Samsung Galaxy Nexus] THS1989:
I never complained about it not being out lol. Hell I didn't even line up, just pre-ordered online and waited patiently....

It's just that: THE VERTICAL LINES...It's worse than the graininess part. These lines should not be here on a $650 phone is really my biggest complaint.

Honestly, it's just a matter of quality control. Some phones are worse than others ??? Well that just proves that it's the QC.

I hope Samsung ups their quality control so people don't get stuck with these visible lines on their $650 phones.

Today I learned there is at least one other human on this planet besides me who understands this. Thank the might Zeus.

If you can notice anything to do with pentile matrix then you definitely have magnifying lenses for eyes.

I'm not buying any of that OP. Sounds like a troll to me.

---------- Post added at 03:31 AM ---------- Previous post was at 03:28 AM ----------

Which is why I call this thread bullcrap. I'm not trying to be some android shrill, but telltale signs like "iPhone is perfect" and "I can tell its pentile" stand out.

No, you can't tell it's pentile (no one has been able to and I doubt he's placed his screen under a microscope).

Maybe you should have bought the iPhone 4 instead.
[Samsung Galaxy Nexus] @rbiter:
I thought it was obvious this person is an apple troll. C'mon. Iphone being better with it's 3.5" screen being compared to a true hd amoled that is first gen. Makes the iphone better? Please. Also, you knew you were buying into an early adoption on all kinds of fronts. Get a blackberry and be done with it.
[Samsung Galaxy Nexus] pcm2a:
The camera on this Nexus is crazy amazing compared to my previous Thunderbolt! The quality of the pictures is about the same but I can now snap pictures, with flash, almost as fast as I can press the button. On the Thunderbolt it is one picture every 5 seconds or so. Amazing!
[Samsung Galaxy Nexus] spovat:
when people struggle to pay upwards of 700 dollah for a piece of technology, they immediately jump on over analyzing every square inch of their new purchase looking to find a fault.. the worst example of this was when someone posted complaining about the battery cover having some 'give' near the camera. its entirely possible that you might have a defective device but much more likely that it's not fitting your expectations relative to the high premium you paid. i can just go by what I see myself and that's a beautiful screen, knowing full well it comes at the price of battery life
[Samsung Galaxy Nexus] @rbiter:
Beat my expectations actually. I thought it would struggle to get 3 hours in a day with my use. I have ~25% left after 12-15 hours of cell data. I haven't been able to test yet but I'm sure I can get 5 hours on wifi. But yeah I agree with you. I think a lot of people had unrealistic expectations. It does still irk me no sd slot though.
[Samsung Galaxy Nexus] AdamNJ77:
TOTALLY AGREE...It's SO FAST, you sometimes get bad pics because you may jerk the camera real slightly. But when you pre focus and hold the camera steady, I think the pics are preddy damn good, not for 5MP, but ANY mobile camera
[Samsung Galaxy Nexus] greyphil:
Just tried that App from first page and I can say: My screen is perfect. Couldn't find a single dead pixel at all. But well... Haters gonna hate. :rolleyes:
[Samsung Galaxy Nexus] player911:
Having a temp rezound for a week, both set to 3G only, and NFC off.

Rezound 8am-midnight with 15-20% remaining.

Nexus w/ extended battery requiring a charge around 9pm.

Although the resound didn't get much use outside of normal tasks. I think I'm playing with my Nexus more through out the day. I also used ADW instead of stock launcher which could affect battery usage. Although the latest ADW crawls on my Transformer... but that's a different topic.

The nexus also uses the GPU more which could put more strain the battery. There are lots of variables. Also supposedly the stock ICS kernel has a flaw where the android system is eating resources.

As far as the screens, I've noticed some graininess but no bad vertical lines. I've notice them if I look at a gray screen but no where else. I can't see them anywhere else. I also use brightness at 50%. Auto pisses me off plus it powers another sensor to drain the battery.

My opinion is to just adjust the brightness so its not noticeable and continue with your lives. The Rezound had a crisp screen but it wasn't as vivid (colors) as the GN.

Although I'd recommend the rezound to my coworker because it just seemed to work. He's not a techie and thus just wants a phone that lasts long. He also liked the thicker body with rubberized back.

[Samsung Galaxy Nexus] darkhawkff:
Honestly, I don't buy the OP. Perhaps his screen is in fact screwed up, that I could believe. But vertical lines? I know I don't have the best of eyes, but with my contacts in I can see very well, I'm an electrical engineer and I normally solder small components onto boards without the use of microscopes. The only way I'm able to even make out individual pixels or lines of this screen is with the use of a 7X lens (I do not have any lenses with a lower magnification). Even then, it's not easy unless you know what you're looking for exactly. With a 10X lens it becomes as plain as day.

Look, I understand that you might not be happy with your purchase. Perhaps your screen is in fact bad, that I can buy. But if it is, coming in here and saying the screen is terrible and immediately jumping to the conclusion that everyone else has the same thing, isn't that just a bit dumb? Why not post a picture of your screen with it's vertical lines. That's what I'd do if I had any question about it. The fact of the matter is, you're either trolling, or just very unhappy with your new purchase. If it is the latter, I'm sorry to hear that. It's a great piece of hardware, and like others have stated, you probably should just go to the fruity side of life.

EDIT:Even after testing the 'dead pixel tester' program and using a 10X lens while on any solid color, it's still difficult to make out any banding or individual pixels. When on my home screen (I use a matrix like live wallpaper...) it's rather easy to notice the individual sub pixels simply because you have different colors next to each other. That being said, text is still clear, even with a grey background. Of course, as usual, YMMV.
[Samsung Galaxy Nexus] tyty123:
I used the app listed. I have no dead pixels or lines. My phone is set to auto brightness. The screen looks fine and better than my galaxy s.

My brother has the iPhone4. I appreciate the gnex screen so much more when comparing the two.
[Samsung Galaxy Nexus] pukemon:
the nexus should fare better if using the gpu if it is efficiently hw accelerating the ui. i already patched my kernel for the 384mhz and i noticed no hit on the battery but i think that the ui doesn't even need the 308mhz stock.
[Samsung Galaxy Nexus] Smokeey:
The screen seems fine to me. I don't see any graininess and colors look really vivid. This might only be because I'm coming from a Droid Incredible with an AMOLED, but this is definitely the best screen on the market right now.

oh and the camera is fantastic and actually takes better pictures than my dinc
[Samsung Galaxy Nexus] player911:
I tried that program and it always put my screen to Max brightness. No lines though but the colors are trippy.

[Samsung Galaxy Nexus] columbo:
The problem with vertical lines is NOT on every Galaxy Nexus. Those that are saying that it is would do well to check that theirs is not faulty.

My Galaxy Nexus, purchased from Three UK, had the vertical lines on the screen as described by the original poster in this thread. Mine also had a slight yellow tint.

I took my phone into my local Three store and compared it to the Galaxy Nexus owned by a member of staff in store, which had no defects on the screen.

Because I originally bought mine from Three over the phone, I was unable to get it replaced in store, so I arranged a replacement to be delivered to me the next day.

My replacement is much better, but sadly has a distinctly dark shadow on the right hand side of the screen, which is very distracting.

I have called Three again and I am expecting a second replacement on Tuesday.

If you are not happy with the quality of your screen, tell your retailer and tell Samsung! Check with a local retailer who sells the Galaxy Nexus to see if you can compare with a demo model, if you have to. Don't make excuses for them.

I would suspect that there may be a problem with quality control procedures at Samsung. Whatever the reason, you should not have to put up with such inconsistency, not with a phone worth this much money.

It's a shame, because without the blemishes, this screen is amazing.
[Samsung Galaxy Nexus] Smokeey:
Can someone take a picture of the vertical lines?
[Samsung Galaxy Nexus] Nutsonfire:
My screen has all sorts of lines on the top half in certain conditions. Also a portion of the screen has a reddish hue to it.

Compared to it my Nexus S screen was perfect and it was also amoled.

One can imagine that Samsung set the bar pretty low when deciding what is a bad screen and what is a good screen... under pressure to deliver before Christmas?
[Samsung Galaxy Nexus] vaxick:
Those lines you are seeing all over the screen are the haptics vibration strips. They are just unusually noticeable on this screen.

As for the reddish hue, that's normal with AMOLED screens. Whites are the weak points of this technology.

I agree overall I'm honestly not impressed with this screen at all. I've gone through two now and they've both had uniformity issues. One side of the screen being brighter than the other side. It's distracting because it's very noticeable. The floor model at the store had it too. This confuses me a bit since AMOLED screens are suppose to be very uniform as every pixel emits its own light instead of having a backlight illuminate them. The same reason Plasma TV's are known for their screen uniformity. Is uniformity a issue with pentile OLED screens I wonder?

The screens also appear to almost have a grainy appearance to them.

I enjoyed the phone, but ended up returning it because the screen honestly bothered me that much. I'm going to hold out for some of the phones with 720p LCD screens. My eyes seem to be much more at home with the milky whites and natural colors LCD screens provide.
[Samsung Galaxy Nexus] Lithium98:
You want the screen to take up the majority of your battery. That means everything's working as it should. Check any other android phone's battery usage and you'll see the same. Display should always be at the top of that list, if not, you have yourself a problem. Also, from what I've notice with 4 different Samsung phones all rocking s/amoled screens, these suckers are meant to be viewed at something more than 20% screen brightness. You get all the graininess and vertical lines when you have it any lower. It's like driving a Ferrari at 5mph everywhere you go. There's no point in doing that. I was kinda hoping they'd have the manual brightness by sliding your finger on the notification bar like all the other Samsung phones (I guess it's a touchwiz thing). The auto brightness sucks.

In conclusion, don't sit in a Ferrari and with no intention of flooring the petal and going 150mph. Stick to the golf cart everyone has fun riding around in, but feels like a jackass when they have to take it out on the road with the real cars.

Huh, Haptic Vibrating Strips?

What? LOL no they aren't.

I've never heard of "haptic vibration strips." Haptic feedback works using the internal vibrating motor, same one you use to put your phone into vibrate mode when you recieve calls.

"Haptic vibration Strips?" Is this something I've never heard about?
[Samsung Galaxy Nexus] Nokstar:
I challenge this guy to take off his screen protector and give a honest 2nd opinion. Why? Because i was stubborn and thought my screen protector was of high quality and didnt degrade my screen. Then i took it off the other day and was amazed at what i was missing. Screen is excellent..there is no better screen out there imo and iphone 4s is the only other screen thsts comparable.

[Samsung Galaxy Nexus] KWKSLVR:
On the reddish hue (which I've noticed when the screen is bright).

Now, I know that compared to my Vibrant, the screen on the GN isn't quite as, errr, Vibrant. The only time I really notice a reddish hue is when the screen on the GN is dim. The only time I really notice it on the Vibrant is when I use "Screen Filter" (app from the market) to dim my screen dimmer than it will go from the factory.

I know that the GN is pentile, frankly, I can't tell. I can't look at it and go, "Oh, that's definitely a pentile screen". That said, I wonder, seeing how the GN is considerably dimmer on the lowest setting compared to the Vibrant on it's lowest setting, if there isn't some form of "screen filter" built into the kernel? The only time I notice a red tint is when things are really low. The screen is perfectly fine to me.

Just a random, probably inaccurate thought.
[Samsung Galaxy Nexus] chirea.mircea:
It means you haven't done much on the phone, thus the display ends up using the bulk of the power. Try running some dark games from full charge to 10%, then see the game come 2nd or even 1st in battery use.

The battery usage statistics show what has been using what percent of the drained capacity; if you keep the screen on but do nothing you'll see the screen use 90% of the battery.

Either yours is defective or you are way too sensitive to PenTile.

That's your opinion. There are other phones with LCDs, even IPS. LG Optimus 2X comes first to my mind; Google didn't indent to make a perfect phone, they made one that's good for most people. Stop making a big damn deal out of every thing you don't like, nobody forced you to buy this phone.

As I said, the lines (picture please) you see sounds like a defective display, or GPU, or software, or something else. Try exchanging it; I don't notice any lines on mine.
[Samsung Galaxy Nexus] EarlZ:
I had the Samsung Wave as my first SuperAMOLED device and i was BLOWN AWAY even if it had a very small screen, it was perfect for my needs. Then I moved up to the Galaxy S1 which was even better and set my standards really high for SuperAMOLED screen. Galaxy S2 comes in and just shatters it! The screen is good but had a lot of different defects and issues, had a total of 7 replacements all bad got a refund.

Now I have an HD SAMOLED device and I get this kind of lines visibile in ANY color but more obvious in whites/lightblues/greys.

Is that supposed to be normal for OLED?

In the top portion you can see a LOT of lines..
[Samsung Galaxy Nexus] RogerPodacter:
The Verizon store here has 2 units out. One screen has bad artifacts and lines, the other has none of it. So there is a big variance. Everyone here bashing others who may have complaints, remember maybe you got one of the good quality screens.

All AMOLED screens have these "lines".

It's more visible on the Nexus thanks to how Google configured the screen.
[Samsung Galaxy Nexus] serialtoon:
I agree and thats why im back to my Nexus S. Ive had a total of 2 Galaxy Nexii in my possession. The first one i purchased from Negri and it came from Latin America (Yakjuxu or Yakjuux?) and it had a perfect screen. No streaks or lines or anything of that nature, but someone i know offered me way too much money for it for me to turn down so i sold it. I ended up buying another one from someone on CList that was a "true" Yakju phone and that one had a much grainier and "liney" screen. It was pretty bad and i cannot justify paying such a large amount of money for one.

To top it off the Nexus S with ICS moves at the same speed as the GN does, with a lower resolution i understand, but no weird display issues. Im the type of person who like to keep the screen well protected, but if it comes from factory in that state, forget it. Ill wait for the GSM version to drop in the states that way i can return it if the screen looks likes crap. Until then, my Nexus S is perfect for me.

Just keep exchanging until you get one you're satisfied with.

My phones only issue is a wonky USB connection that disconnects when you love the phone. I'm afraid to exchange it due to the other issues I've read.

Turn off auto brightness, it runs down the battery. Set the brightness to 40% or lower. Higher brightness only washes out the colors.
