Screen brightness...

I just switched from a GS2 to a Nexus. I love the more natural colors on the Nexus, while the colors are amazingly bright on the GS2, they just look too saturated and cartoony to me. So the tamer colors on the Nexus are a nice change.
What isn't quite as nice is the overall brightness of the screen just seems lacking a little compared to my iPhone 4 and GS2.
I usually run my phones at half brightness, and while it isn't dull by any means, it just seems like the screen should be brighter.
Still the best screen I've used on a mobile device though.

I'd also like to add that I don't think the lack of brightness is really a bad thing, just curious about it.
The GS2 had a ridiculously bright screen and the colors were just so saturated and cartoony, a great screen, but I prefer the more natural, modest look of the Nexus. I found the GS2 screen to be hard to look at for some reason, something about the high contrast made it weird on my eyes.
I find the Nexus to have sharper text than the iPhone 4 I have, but the iPhone 4 still has the "cleanest" screen I've seen.

So turn the brightness up higher than half brightness. Why does it have to be at half brightness, when you obviously prefer a brighter screen? Set it to whatever you prefer, rather than what it says is half brightness.

haha, well...I suppose you do have a point. I guess I'm just used to the iPhone 4 and GS2 being brighter at half brightness. There's something about the battery conservative in me that finds it hard to break that 50% mark on brightness, although 80% of the time I'm near a charger anyway.

I'm starting to think that Google calibrated this screen to be easy on the eyes, especially for reading text. The natural colors and tempered brightness just seem deliberate. I do understand that the Amoled Plus on my GS2 contributed to the colors/brightness being so in your face, but calibration can change a lot. Again the GST is very nice, but just a little too much, the GS2 wasn't that easy on the eyes.
As much as I like the brightness of the other devices, I find reading on this phone to be a pleasure. I was more just curious about the brightness on this phone, not even sure it's really a preference just an observation. It's early, I hope I'm making sense.

but.... not all phone's brightness meter are the same... half way up on phone x is probably not the same has it is on phone y...

Yeah good point..

I agree the colour temperature is much more natural than the S2. I do think we could do with greater contrast in the video player as it just doesn't "pop" in the same way. S2 appears much sharper and much greater contrast when playing video especially on lower resolution videos...

Just got my Nexus, fantastic device but I noticed the screen is a lot less bright in max brightness when I put it next to my Galaxy S.. I guess I'll have to get used to that.
Also, anyone else notices a reddish hue, specially when browsing on a white background. Don't know if it's because my eyes need an adjusting period from my old i9000

Is this normal for all SGNs or do we have a bad batch?

Mines the same especially on the right edge. Hopefully the member who calibrated the s2 could calibrate the nexus

haha I made this thread in error. I actually took my phone and compared it to a GS2 in store and it was fine. Just a case of thinking the grass was greener.

I just cranked my brightness all the way up on the Nexus as well as my 2 year old HD2, and the HD2 seems overall brighter. Other folks here are saying the same thing about their Nexus. Any other observations?

Screen problem: Is this affect of Pentile Matrix or not.

Hallo friends, i read lot of about problem with this kind of display( pentile matrix)
I have vertical and horizontal banding too. But this one is something what is bothering me much more.

That's nothing to do with the Pentile Matrix! Definitely a defective screen, return it to the store and ask for a warranty replacement. The 'banding' is more to do with the AMOLED screen technology rather than the Pentile, as it was present on my SGS2, but is generally only visible under certain conditions (background colour/brightness).
Regards.

Is it visible on colors other than grey?

Sure, on blue background too,sometimes on white.(poarws photo with blue background) It depends on brightness.
More visible at white background with high brightnes.
More visible at blue and grey background with lower brightnes.

It does have to do with the Amoled technology, but I doubt it's a defective display. You can try to exchange it to see if it really is defective or not.

I have some vertical and horizontal banding only with lowest brightness at the white background.
With maximum brightness no lines or whatever

AMOLED has a few imperfections here and there, so it's not surprising. But if it's bothering you too much exchange it for another one, it could have less prevalent issues.

Just performed a test using screen test app my screen looks great.

How high is brightness with test screen
Mine is fine too but 60 percent and more.But this one issue bother me pernament ( no matter if 30 or 70 percent brightnes)
Tuesday iam going for a new piece, hope that will not be affected worse than mine

Try viewing those shades of grey on your phones, it's usually the most problematic color. Use a low brightness setting (around 25%) at a dim environment.

This exists on all OLED screens. Its the exact same on my Nexus S. It has nothing to do with pentile matrix, but OLED.

Yes i had nexus one galaxy s galaxy s II so i can compare,nothing like that before that.
50-60 percent of brightnes

I have the Galaxy Note and it has the same panel as the Galaxy Nexus albeit at 1280x800 instead of the Nexus's 1280x720. (Super AMOLED HD with Pentile sub-pixel arrangement)
My screen is great. The whites are brighter than they were on the Nexus. The Nexus displayed whites with a yellowish tint especially on low brightness. Plus I can't seen any banding on the screen and I have tested it on White, Red, Blue, Green and Grey backgrounds.
Im getting a new Galaxy Nexus in a couple of days. Since this unit is from a later batch I hope that there is no banding on the screen too.

Funny, I have a similar issue to Delarock's on my Galaxy S2, manufacturing date is 19th of October. I'm still thinking whether to replace it or not since since it's only visible on dark'ish grey, I couldn't replicate it on lighter greys, white, or any other color at various brightness settings.

Hard for me to get a good photo but you can see the same problem on my NEXUS S screen. Its just a characteristic of OLED displays in general.
Sent from my Galaxy Nexus using XDA App

Really similar to the screen on my new Galaxy Nexus. I didnt notice the diagonal right away but that is certainly more significant. My screen a rosy hue in the bottom half and especially the lower left.

I'd love to see a similar picture of someone who says that their screen doesn't have it.
(Click for 100% crop)

So are some of these screens defective? Or is it really just the nature of the beast?
How does one tell what manufacturing date their device was made to? Would I be able to go to a store and exchange for a datecode that shows no banding issues?

I am having the same issue ... another thing I notice is weird issues with the camera while in a dark room. If I have my camera on in a low light room, I get this weird "dancing" of black blotches in the really dark areas of that room.
I like all solid black wall paper, I find the fastest easiest way to get it is to turn off the camera flash, put my finger over the lense and take a pic. Worked for every other phone I have but the GNex. I get a weird blotchy image ... now I am on GNex#3 (other 2 I returned for different issues) and I have noticed this camera thing on #1 and now #3. With the first one I assumed this was normal ... but after going from the second one to the third I see a HUGE difference in screens. With phone #2 I was able to do the phone/black wallpaper with no weird distortion. Now the really strange thing is that that same pic taken with the second phone (that displyed pure black on that device) shows up blotchy on device 3.
Hope this makes sense to someone lol cuz reading it back I sound crazy.
I just hope the folks at the Verizon store don't give me a hard time trying to get another one!

Is the galaxy nexus screen artificially limited in brightness?

GSMArena did a display test on the galaxy S3 and it is much brighter at full brightness. Galaxy note is also much brighter so why is it that the nexus has such a dim HD SAMOLED screen?? Is it software based so people dont end up with terrible battery time??
I so so wish the nexus can have brighter screen, my biggest complaint with the phone.

Probably better for Q &A, but AOSP and vanilla Google Android has always been overly aggressive about auto brightness and keeps it quite dim more often than not. It can, and is modified by OEMs and some custom roms.

I'm not sure my screen is as dim as what other owners claim theirs to be. I have it on auto-brightness and I don't have an issue with bright outdoors or indoor. I'm not sure I'd like it to be any brighter than it already is.
Maybe I'm not used to having my screen burn a hole in my cornea.

I am talking about full manual brightness, auto brightness is never perfect on any phone but it actually isnt dim at all on my nexus S.

Dunno. I am not about to go run to Best Buy and compare, but full on brightness on my phone is uncomfortably bright in the dark and dimly lit areas, and very visible in direct sunlight.

I tried the phone at a very brightly lit shop. Put the brightness to maximum manually and yet it was barely brighter than my nexus S at 50% brightness.
Brightness isnt a contest where every phone should try to beat others but it should be sufficient enough. I just think the nexus brightness isnt sufficient, it tops out at 200 nits when the minimum should be 300 nits for comfortable use in all environments.

Do you want a discussion, or do you want to discount what I am saying just to argue?
Don't ask for an opinion if you are just looking for a way to discount it.
Your sites cannot vouch for my experience.
If your phone can only match 50% of what the Nexus S can in brightness, there is something wrong with it. That or you are exaggerating. This is in my opinion, but I think it is a very valid point.

The screen seems to be limited in brightness from the factory, as a matter of settings. Using AOKP Rom and increasing the color multipliers makes the screen much, much brighter, but i've read speculation that it could cause the screen to burn-in images much faster, which logically speaking, seems to make sense. Maybe it's limited by Samsung for that reason. This particular panel seems slightly more prone to image retention than the one on my Droid Charge, granted it isn't the same as burn-in, but maybe an indicator of inclination toward it...

The GSIII probably gets 2 mins of battery life. A screen that bright on 4 Cortex A9's and 4 mali 400's at 32nm....the battery is going to SUCK.

I was not asking for opinions if the screen is dim or not but why is it. It wasnt my phone but a demo model at the shop. My experience showed me it was dim just like I had read in reviews.
I have an LCD nexus S, I am sure the AMOLED one at 50% wont be almost as bright as gnexus at 100. You know LCD's can get much brighter and the one on nexus S is particularly really bright.
I also compared galaxy nexus side by side with galaxy S2 and the difference was noticeable in brightness.

The GS3 is only 300 nits bright, it isnt anything out of the ordinary. The one X has 500 nits screen.
And nobody is forced to keep the screen on high brightness, it's just an option to have a really bright screen and a pretty good one at that.

I thought of it when you mentioned the GS2 - I had that phone for a week when it was released on Sprint, and any time the screen brightness was turned up and the screen was on for a few minutes, it would overheat and the OS forced it to low brightness until it cooled. At the time it was an issue quite a few people seemed to be having, so maybe it's limited on the Nexus for temp reasons too. As Smokeey had mentioned, battery life could be a factor as well.

Do you even OWN a GNex? I swear you're just here to troll the device.

Why cant I post if I dont have the device? I am thinking about upgrade from nexus S and I just made some threads about the potential issues I discovered about the device.

As long as you can see the screen who cares how bright it is. Are you trying to light up a room with it? Also, keep your phone on full brightness and you will be highly risking screen burn in so I would not recommend keeping it on full anyway even if it is not as bright as other devices.
Why would anyone purchase a phone or not purchase a phone based on it being the brightest screen out there. I can understand if you couldn't see the screen, but really? And now with the ability to change the colors and gamma of the screen, it just looks great.
So if you get the Nexus and keep the screen turned all the way up because you needed to light up your house to save money on electricity, please don't start a thread complaining about burn in.

Ah keep LCD phone on full brightness and deal with the terrible blacks. Keep an AMOLED phone on full brightness and deal with burn-in. A perfect world we do not live in.
On a serious note screen brightness matters most when going out in the sun obviously. It can never be too bright when you are out.

So everyone has purple issue at low brightness.....

So I just got my gnex last week and I know that there are issues with purple color at low brightness so my main question is do most just leave the phone on full brightness all the time?

Full brightness? Wow, that would just kill your battery. I just leave it on auto. I never had had the tint issue though.

Anything lower than like 60% for me has purple tint. I have adjusted and used Franco's kernel and everything. Should I request a replacement phone while I can because I don't know if this is normal or not

That's not normal. I get it at the lowest brightness level. I usually have mine at 30%.

I have no purple tint at any brightness.

If it really bothers you you're within your rights to exchange it.
However, there's no guarantee that your replacement will have better tints and there's the possibility that it will have a different sort of defect instead.
I exchanged my purple GNex and received a new one with a dead column of pixels. My 3rd unit is flawless though.
Just be aware that you could be starting a long, tedious and frustrating process of exchanges until you find your Goldilocks Gnex.

No tint at all for me..
"Long is the way, and hard, that out of hell leads up to light."

At the lowest brightness I see the tint you speak of, but anything above that it looks ok.

I've actually gone through 3 devices recently, and on my second one I definitely noticed this issue. Another thing strange is that there was a clearly visible circle at the place where the LED is (under the screen) that is completely invisible on the other two (which do not have a purple tint). I don't know that they're related, but it's just an observation.

Mine has a purple tint at any brightness lesser than 50% also it has a horrible yellow tint, which i managed to improve a lot by using franco kernel color control but the till os still there, since I bought from Amazon us and I live in latinamerica an exchange is totally out of the question I'd say fight for an exchange until you get a perfect screen
, brightness at 100% is too bright for me and besides it eats up the battery. I leave auto brightness on most of the times but it can dim the screen too much, it's very aggressive, so sometimes I just set the brightness to 50%

Good place to check, i don't seem to have it on any setting of brightness

Mine has a little bit of graininess at 0%, but anything over 0% and I can't tell.
As for the purple thing, my whites have a slightly blue hue, when not looking head on, but again, it's so faint and not really noticeable that I don't care, plus the brighter I go, the less i notice it.

Mine has a horrible purple tint as well as heaps of other issues. Even on full brightness, the purple still shows through in some places, like the settings menu.
I tried sending it to Samsung and they kept it for two months, did a data wipe, and sent it back to me unfixed.
Edit: And yes I leave it on full brightness all the time, and I still finish the day with about 40% battery left.

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

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!

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

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.
