[Q] These HD sAMOLED screens kinda suck

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....

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...

Honestly, I don't see the graininess,even with this antiglare screen protector I have on.

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.

Try this. Set your background as a solid dark grey color. I guarantee you will see the imperfections.

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.

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)

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

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.

OK fair enough.

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.

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)

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.

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.

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.

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!

HD Super AMOLED Eyestrain?

Does anyone else experience eyestrain with devices that have the HD Super Amoled screen?
I notice after about 10 - 15 mins of use, I get dizzy and my eyes hurt like they are being crossed or something when using the galaxy s3 or galaxy note, my old galaxy s2 skyrocket doesn't bother me though....
I've tried to turn the brightness down all the way, using the device at different distance to no avail.
Any possible solutions to remedy this? or am I going to have to sell my new S3 like I did my galaxy note? :/

depends on 2 very important factors...
1- how much cheese I've smoked
2- what was the question again?

I've actually noticed a decrease in eye strain coming from an LCD screen on my atrix. LCD screens are constantly flashing, and the screen on my galaxy s3 is super clear for me almost no eye strain. Its probably personal preference though.

I've actually experienced the opposite as my first android device was an atrix....
I think it may have something to do with the 1200 x 800 resolution on such a small screen because If I turn up the resolution on my PC HD monitor to something like 1600 x 1200 for example, my eyes start to hurt.

I was actually going to post a new great until I saw this. I came from retina displays and my eyes are sore after I look at the screen for over 10 minutes on my GS3. Kinda concerning!! Might have to switch back to an apple product. I was getting use to droid too. :-/

its because of the screen size/pixels. Your eyes still needs to be adjusted to the new screen lol... obv

Yes!
I got vertigo/migraines about a month after getting my S3. I had a number of medical tests to see what was causing it - but even after new glasses I've narrowed it down to the S3 display being too strong for my eyes. I'm going to sell mine and get a replacement with a duller screen.

Try this...
Try changing the Screen Mode to 'Natural' or 'Movie". Helped a bit.

I also immidiately noticed eye fatique after getting Galaxy s3, particularly in my right eye. It started only getting worse, and coincidently only when I was using Galaxy. Other lcd devices such as older 3gs never bothered me at all. Surpisingly majority of reviews call the display stunning quality, but its pretty dim, practically unusable outside and colors are unnaturally oversaturated, all of which didnt bother me that much as long as my eyes wouldnt hurt so much. I started reading more about specs in Super amoled technology, but nothing pointed out to potensial issues, than I googled galaxy s3 refresh rate, and the first video from the search result comparing s3 to the iphone, provided a major clue. The poor quality camera was picking up horrible flickering from galaxy, but iphone screen didnt flicker at all. It instantly brought me back to old CRT days, and I also remember getting dizzy from such displays running at low refresh rates of 60mhz. Back than bumping up refresh rate to 75mhz conciderably dicreased eye strain. I took the video to the store, sales person was suprised that I was returning such popular product, but its been a day since my exchange for another brand and eye strain is gone. The issue maybe overlooked as it affects low percentage of people, but if you have sensitive vision, than you'd be much better off with non hd amoled technology

Could it be the brightness?
I'm sure your not holding it against your nose while watchin you tube, but maybe its the overall brightness of the screen thats getting to you? I use a powersaver app that has a black screen filter that dims it out a good little bit, maybe something like that could help, or a matte finish screen protector...the anti glare ones I think.

Use the "Screen Filter" for use at nights.
Set brightness to 0, and enable filter. I set mine at 48.6% and 36.9% (created two widgets with these percentages) and use either as needed.

Set your brightness lower. It's the brightness of your screen. I have the same problem before turning down the screen

Keep phone at safe distance from face. Try a dark theme or inverted apps, or both they will most likely reduce eyestrain as well as save battery.

Hi all,
There are a lot of users who feel uncomfortable with AMOLED displays (not all of them, for example sgs2 is not affected). They can struggle with head ache and eye strain. You can google "galaxy s3 eye strain" for example or watch how AMOLED blinks through photo/video camera (there are tons of youtube videos). This effect apperars only when screen brightness is not at maximum level. The nature of that is the mechanism used for brightness control. Instead of forcing the pixels to glow at less brightness they force them to blink very fast. The faster pixel blinks - the brighter it seems to the user. The downside of this is that the whole screen blinks as an old CRT monitor which causes this negative effect.
I found an app which could help us to workaround this issue. I filed a feature request. So if you are interested you can add yourself to wathcher list and post a comment here - https://bitbucket.org/VitoCassisi/lux/issue/38/lux-auto-brightness-feature-request-for
This should not take a lot of time since you can authorise there with your google/facebook/twitter or other account.

Wow! I switched the screen to "natural", the problem with oversaturared, too rich colors was solved. I had to keep the brightness low so color pictures aren't too bright, but this made reading text on white backround unpleasant. Of course now I have to find new brightness levels (what brightness levels do you guys use for day and night?)
PS: Samsung has been doing similar tricks with the colors in their TVs. Some series 6 TVs made the picture look like it was from a heat sensor in dynsmic mode, and this was their default mode.
PPS: Mobile screens suck. LCDs have washed out blacks which strains the eyes, and AMOLEDs don't care about correct colors which makes you duzzy.

S3 screen flickers!

You are absolutely right. S3 screen flickers a lot. Try to move it quickly in front of your eyes, move your eyest when looking at it, or move your finger fast in front of the screen. I certainly do notice it.
What other phones have better displays? Sony? HTC?
I have a solution to resolve galaxy S3 scren flickering: set brightness to max in settings, install an app like "Screen Filter" (one with black-white rectangle) and decrease brightness there, in the app.
Flickering gone!

Most of phone LCD screens are not affected by flicker. Even some amoled displays too. For example old HTC Legend and galaxy S2.
Galaxy note 3, 4, Galaxy s4, 5 are also affected. I strongly recommend you not to buy any new samsung phones equipped with AMOLED screens.
Now with this https://play.google.com/store/apps/details?id=com.vito.lux software you can get rid of screen flickering issue. Automatic brightness adjust will also work.

[Q] 800 pixels width vs 720 - discuss

The only thing putting me off the note 2 is the smaller screen resolution. I can imagine apps like the samsung calendar must be less usable. Also I find 800 pixels is a dream resolution for viewing internet pages.
For those that switched from the note 1 how are you finding it?

Is the less dpi really that noticeable? I'm actually very excited about the new aspect ratio as I watch a lot of movies on my phone

Finally a thread like this
It's really annoying in some situations but then you launch a video and your stunned.
You browse, somehow less good, it's quite noticeable when you had Note 1 but then the screen is so much better in ALL other aspects.
Then you get no problems with app compatibility due to the more standard resolution. You see more webapps and games thought for 720p.
So wrapping up, I guess I'll get use to it and with all the other goodies on Note 2 it's worth the upgrade: amazing batterie life (doubled), screen colour and brightness, speed and great sound.
I'll keep the nostalgy of the original Note owner though :<

Isn't the one lesser column of icons also the result of less horizontal pixel? Yes I agree the screen is much better, but I don't suppose it's just for web viewing. There are the utilitarian point of view to this. I would imagine people who used to have certain amount of icons on a single page and then suddenl reduce would feel negatively. It's like taking a feature out. I am coming from an Epic 4G so I got no bone to pick on this just voicing another valid PoV that some people didn't see.

Sometimes I'll do something and my brain will go, 'that looks a bit odd', because I remembered how it was before.
But you'll get over it. The Note 2 is THAT much better.

[Q] Note 2 Display Quality

I checked out the Note2 again last week this time only for about 15 min when I stopped by Best Buy & immediately felt like this is such a real huge upgrade from my EVO 4G that I must have it soon. Then I started noticing the whites weren't as white as my EVO & it could be brighter (set to max) & even experienced some lag but I did not have time to do a reboot.
I'm somewhat curious to see the Droid DNA, 1080p natural color screen with amazing cameras like the OneX & improved speaker etc but obviously annoyed with battery & sdcard situtation (not a huge fan of all the red styling either but would slap a case on it) so I'll check it out. I think the OneX variants are the best "smartphone" display & camera & at 5" DDNA should be impressive (always thought 5" is a great size but the N2 managed its 5.55" amazingly as well & the stylus puts it in its own class).
The following links seem rather disappointing for the Note2:
http://gizmodo.com/5960289/htc-droid-dna-vs-iphone-5-and-everyone-else-whos-got-the-best-display
http://www.technobuffalo.com/compan...t-8-core-processor-13mp-camera-1080p-display/
So do the non-white whites & brightness of the screen especially around sunlight on the N2 ever bother anyone in real life use?
- Thnx

Funny, if you research the specs of the Galaxy S3 from a year ago, these are the same specs they said about it back then that they are saying about tbe S4 now.

I remember S3 rumors of a 13 MP camera & 1080p screen (but not @ 4.99") & quad core not 8 cores...
So can I assume the non-white whites & N2 brightness especially around sunlight on the N2 doesn't bother you in real life use?
The S4 & Note3 will likely have 1080p screens & hopefully whiter whites & greater brightness so the Note2 will not likely last as long as I'd like as a primary handset anyway..

I love the screen, the whites don't bother me a bit. I also, however, do not walk around with another screen next to mine. The grass may be greener, but my grass flack out rocks!

I did do that the last time at Best Buy & while it did lower the color saturation it did not obviously make the whites any whiter or the screen brighter. I found myself going back to the default standard color mode but I do appreciate having options..
Even compared to my 2 yr old EVO, the whites are not as white & screen seems less bright overall.
I still think the Note 2 is the best overall handset ATM but the display could be brighter with whiter whites & higher res which will likely all be there on the Note 3..:good:

Good to hear, the whites& brightness on this notebook i'm using ATM are not great either & mainly notice the difference when comparing or using another but my next one should be noticeably better..

+1:good:

While I mentioned that I appreciate the Note 2 screen mode options, in tests I seemed to revert to the standard default color mode as changing screen mode only affected color saturation without obviously improving the whites or brightness or sharpness which all seem better on the HTC One X. The default standard color mode seemed to make the screen less dull than Movie mode so I'm curious how many people actually primarily stick with other modes like Movie etc?

Tab S 8.4 vs. Xperia tablet z

I can't compare with the tablet Z, but I own a Tab S 8.4, a Nexus 7 2013 and a Note 8.0. I will try to answer your questions based on my experience:
The tab S 8.4's screen is a huge disappointment to me. It looks awesome in bright environments, the high pitch and vivid colors are pleasant to my eyes. However, for someone with high expectations as I did, it suffers from several issues that used affect previous AMOLED generations and totally ruin my experience:
- Smearing on black backgrounds. An issue that was already reported on Galaxy S4, and that seem to affect Tab S 8.4 as well: A dark red smear is visible when watching movies on black backgrounds. It looks like black pixels are slower at displaying a color than already lit pixels. The result is not obvious on first watch, but once noticed becomes a nightmare in dark movies.
Here is a fix for this issue: http://forum.xda-developers.com/showthread.php?t=2259775
While this seem to be pretty efficient fixing the smearing issue, the result is not perfect, it is rather annoying to use AND we lose the benefits of perfect blacks in the darkness. And it impacts battrery life, as a dark grey pixel is powered, while a black one is not.
- Mura effect. Basically, dark (but not black) colors are not homogenous on the screen. It is only really noticeable in the darkness, wich is my main usage for the tablet. Rather annoying, especially since the fix for the smearing issues induces replacing all "black" by "extremely dark grey", which reveal this issue.

- Yellow/greyish tint. This one is'nt the worst, but can be felt on white backgrounds. This one becomes obvious when compared directly to a more natural white screen: the middle of the screen seems more yellowish and darker than the borders. It seems like the glass could be dirty, or tinted by years of heavy usage, which it is not.
None of these issues are obvious to someone who doesn't set his standards very high. They are for me though, and will probably be noticed by people willing to use the tablet in the darkness.
As a bottomline, I actually prefer the display offered by my Nexus 7 or iPad mini retina rather than the Tab S 8.4's. They lack the "wow" effect of vivid colors and the perfect blacks, but provide a more homogenous experience, especially in the darkness.
Now for the performances, I don't know what's wrong with this tab. I was thinking about putting the blame on TouchWiz, but alternative launchers don't help. Rooting and turning off as many services as possible didn't either. Here is what I noticed:
- System zoom effects are subjects to stuttering (opening new app/window, for example). None of my other android device suffers from similar issues, and zooming in other apps such as web browser works flawlessly. The issue is not reliable, and seems to reduce when the same window is opened and closed several times in a row. Memory access issue causing stuttering ?
- Overall system doesn't feel as smooth as it should. Even my elder Note 8.0 feels butter smooth compared to the Tab S 8.4, which I can hardly explain. It is fast enough, but the FPS seems to be lower.
- Two of my favourite apps suffer from low FPS when scrolling: Perfect Viewer and Moon+ Reader. The poor performances make the experience with these apps less enjoyable than on N7 or Note 8, which his hard to explain considering how much more powerful the Tab S 8.4 should be.
- 3D gaming is not at its best either. Performances are clearly below N7, and maybe even lower than on Note 8. There, I guess this is the cost for the extreme pixel density of the display panel.
If you are satisfied with the services offered by your Sony tablet, I'd suggest to stick with it. The Tab S 8.4 is a very decent tablet but not perfect, and its major strenghts are also its main weaknesses.

My 10.5 tablet doubtlessly has the best screen I've ever seen on any device. Sure, a k1 is faster CPU and GPU wise, but for my mainly media consumption and Web browsing it's amazing. Haven't experienced any of the issues mentioned above so I guess pentile does detract a bit.

Your answer was perfect for my needs as my main utility for Tab S would be perfect viewer and moon reader as well.
Reading all sorts of experiences I'm beginning to wonder if I should buy a new tablet or not and it seems that I will rain check this purchase for now...

since in some country you can like send it back if you not satisfy kind of sale.. and if it apply to you why dont you test it. i dont have any problem like being mentioned above. and in this short period... i think the QC of the device are kind of loopy... some got great functionality without any problem and sadly some does.

Regarding the screen, I couldn't find reports about the issues I mentioned above for the Tab S 10.5. It looks like the screen on the 10.5 is using a newer technology that would fixe these issues. I so wish it would be the same for 8.4 !
Not everybody is noticing these issues on 8.4, but then I believe it to be related to lower sensitivity to the issues. They are not obvious at all, and basically impossible to notice in lightened environments and/or watching colored images.

I'm not having any of the issues you highlighted with the screen. If you have already voided your warranty it would be interesting to see if you have the same issue with my asop build.

Not having any issue with my tab s 8.4 here... love this tablet.. i was a user of nexus 7 2nd gen..

As a newb at flashing roms, I didn't go further than rooting at the moment.
Regarding the screen, while I am surprised that people report not noticing the issues at all, I am convinced many just don't notice them.
The smearing is actually more felt, guessed than seen. But once noticed, it becomes an annoyance.
The green/yellow tint is only visible on white backgrounds and when comparing to other screens or looking at it for a duration (reading e-books or internet webpages). It's far from being obvious on first sight.
The Mura effect however should become obvious to anyone looking for it. You can try with the follwing steps:
- Download and install screen adjuster.
- Get in the complete darkness
- Launch Screen adjuster, and set Red, Green and Blue to +5. Make sure it's switched on
- Look at a completely black background
=> The black background won't be black anymore but very dark grey. This is what Screen adjuster did by adding +5 in each color. If the screen is affected by mura effect, some areas will be lighter grey and others darker.
This is an issue that affects the 3 tab S 8.4 I tried (I exchanged it twice), as well as my Galaxy SII and my PS Vita. I just wish it wouldn't be the case, but I have yet to see an amoled display that isn't affected, and can hardly beleive I would be cursed badly enough to always get faulty units.

No issues on mine. The screen is superlative!

I've already tested mine T800 for mura with many shades of grey and no issues found.

Yes, from my readings here and there, T800 screens whouldn't suffer from the same issues. They use a different technology though, I wish T700 would be using the same.

yes. me too.
"ukael" is right.
I had this problem on my both two Samsung Tab S 8.4 LTE T705.
on first I thought it is related to that one, but after purchased 2nd Tab S 8.4 T705, I noticed screen going yellowish.
specially in middle screen while in horizontal rotate specially reading something that has white background.
