YUP 100% the browser brightness is very low hence why its darker lol

yup, either browser brightness is low or you enabled "auto power savings" in display which displays darker whites to save energy...either way my whites are proper white even on low brightness so you must be doing something wrong in your test.

That, or the camera under exposed the amoled screen because of the brightness of the nova display. Keep in mind that good LCD screens like Retina display or the blackberry ones are about twice as bright as a super AMOLED screen, so the Nova display might be even better than that (but on the other hand the blacks are infinitely darker on amoled, which makes the contrast ratio infinitely better).

sorry but that looked so biased towards the optimus in the last 2 tests, if you had the SGSII at full brightness in the web browser test it clearly would of won by miles. Aswell as in the sun light test.
Edit: I retract most of that to make it in all of the tests xD.
In most of the pictures the LG Nova screen has very washed out colours especially the first one. Samsung Galaxy S II also hasn't been put on full brightness for this as the other phone obviously has. If you were trying to get away with thinking your LG Optimus Black screen was better than Super Amoled Plus then you've failed.

I set the same (maximum) brightness
It's how BlueScreenJunky said. I tried to set the brightness setting also on the camera but the result was the same

I really don't want to have to take pictures in all seperate conditions to show you what a real SGS II on 100% brightness looks like. -.-

what he meant was that there is a second setting related to power that affects screen brightness

I don't care if the NOVA screen can wash dishes, it still comes attached to an LG phone. After my experience with the G2X and reading the O2X boards, I can't believe people are still buying LG high-end phones. LG should stick to TVs.

did u check that the browser brightness is set to maximum as well? Hmm I just turned mine up all the way and the whites were so bright I thought the rapture was happening after all!

Pictures don't mean a thing unless they're taken with the same camera and the same manual settings? here are 3 pictures of my SGS2 at 100% brightness with the same camera, same shutter speed (1/400 sec), same iso (400 iso), I only changed the aperture (f/1.8, f/2 and f/8):
Doesn't look that bright to me in the last picture...

New Galaxy S2 Batch Better Screen

I have bought 2 Galaxy S From the first batch for me and my.
Now I just purchased one for my father.
And his screen is much better, may be it is just the calibration
But the color seem more bright, vivid and white.
the color of mine is more yellow.
Just a thought
May be Samy improve for the last batch

No pictures and it didnt happen..

mine is very white as well, I have seen the ones with yellowing and mine doesn't have it.

May be is only that i don't have chance and the 2 first i get is like that.
In fact i don't see a band like other thread mention, it just like calibration thing.
But it is ok, if i haven't see my dad's one i would never notice
i don't think picture would reveal that small details, and will send his phone to the dad day.
Thx

Have you checked the Settings>display> Background Effects to verify both are on the same setting, and yours isn't on movie?

I read somewhere that some specific models have a yellowish colour problem on the screen..
This really shouldn't be normal, so my best answer is to send it in for repair

No yellowing on mine all looks good.

Are both phones using the same brightness settings?
On my phone, when the brightness is low, whites have a yellow cast, but on full brightness, they look very good.

Mine is white as well. No yellowish color or pink spots on camera shots.

What he described is not the problem that people are facing.
BTW Engadget are simply repeating what people are saying here. They have no information of their own and it was people here mailing them that alerted them to the problem in the first place.

I've noticed on mine that the colour temperature gets warmer at lower brightnesses. Also dark grey takes on a brown cast. On full brightness it's perfect though. No left hand side yellow cast either that I can see.

There's 60 pages of discussion on this already and the points you're making have been made there a dozen times. Do we really need another 60 page thread on the exact same issue? In the other thread there's also a code to tell what version of screen you have. It would be interesting to see if the claimed "new batch" has a different version.

The main question arises....HAS THE BANDING issue been rectified...so i can FINALLY go head with my S2 purchase ? I'm hesitant to purchase such an expensive device..KNOWING it has a very obvious banding defect...and it seems samsung is unaware of its existence!

I had to ask this question, when I had my S8500 I always set the Brightness to 0, still the screen was enough bright with vivid colors and good contrast looked very sharp and there was no Bluish tint on the screen. But here with S-AMOLED+ if I set the Brightness to mid level or higher then the screen performs well and probably beat the former screen. But when it's set to Auto brightness it seems that the screen has a bluish effect and the whites are not perfectly white, the pictures are not that crisp like it was on the former one, in this case I'd easily say that former screen was better. Now is this a feature of S-AMOLED+ or problem? In low or 0 brightness it is the S-AMOLED which perform much better but not S-AMOLED+ !

Nexus 7 brightness problems

Just got the nexus 7, but...
When I change the brightness through the power-control widget or settings/brightness, on or close to the lowest level it turns off the display completely. I can't see anything no matter what the lighting condition is. Is this a software bug? I don't see how I can turn it back easily.
Another problem, when reading book, the light from the left bezel bleeds and I have a darker top-left corner. It is kind of annoying.
I also have the flickering problem when the brightness is set on the mid brightness... software updated right after startup.

Anyone have the screen completely off when turning the brightness down?
I also happen to have eight stuck (white) pixels...

Yeah, I have a very similar problem to what you described.

My backlight bleeding is very similar.
Does your screen get completely black when the brightness is low? Now, even when I turned on the automatic, it gets complete black. Is it just me or everyone else the same?

No, it does not go black at min brightness here.

I just got the Nexus 7 and the light bleed is Horrendous. I have owned a Asus Transformer before and expect some light bleed but this is really really bad. Like WTF

Mine looked exactly, so I went back to staples for a replacement. Luckily, they have one left. The bleeding on the new one is unnoticeable and the brightness settings are all normal.

Wow. I thought my transformer bled light bad. I'm not feeling so bad now. Of course it has some other weird issues, but has been mostly reliable. If it acts up too much I'll just send it back. I've had it for almost 30 days and can't find any real reason to take it back. It reboots every once in a while if it gets overloaded or too hot (did it today in the sun..of course I had it overclocked too.....) and I've opened the dock to see that it has shut down for some reason, but its not a huge deal. Other users have reported the same, so clearly something isn't perfect. I came to this thread because I heard that the nexus has huge issues. I was curious to see what people were reporting. if I got a nexus like that I would be p****ed! There are reports of them locking up on startup. My transformer just keeps chugging along. Really I've had more problems with apex launcher than ICS on my tf300t.
edit: the light bleed is barely noticable on mine actually...only in darkness does it seem bad. I heard ips displays have issues with that, so took it as good enough for "spec" and really its not all that detractable unless I sit in perfect darkness. Video looks pretty great on the display.

[Q] Lowering actual panel brightness (below minimum)

Hey guys,
I've searched these forums quite thoroughly, and I haven't found any kernels/ROMs that allow for the display brightness to go past its minimum brightness settings. If you've had an iPhone, you'll know that the iPhone's minimum brightness is so much lower than the Nexus 4's. It makes using it at night so much easier on the eyes.
In all the threads I've come across, people just suggest to use Lux, or any of the other apps that just put a filter over the screen. These just make the screen grey, and just mute the colours - they don't actually reduce the brightness past 0.
I know that lowering the minimum brightness is possible; at least it is on other devices. On the Nexus 7, M-Kernel has a file that you can edit to change the panel's minimum brightness, and on my old Xperia Play, the RootDim app [https://play.google.com/store/apps/details?id=mobi.pruss.superdim&hl=en] allowed lowering the panel's brightness.
So, has anyone come across any kernels/ROMs that actually allow reducing of the panel's brightness past 0?
Oh, and I emailed the guy who made the RootDim app, and he mentioned something about pwm drivers. Does anyone know more about that?
Thanks!

I think I was able to do this on my old phone (HTC Wildfire) using Cyanogen. But no guarantees. Also, no idea if that is still supported or works on the N4...

If it's purely about using it at night I would recommend Screen Filter. I prefer not to mess with forcing my screen to use values outside the tried and tested boundaries set by the manufacturer.

For what it's worth, the "lowest" brightness by default is 5%. CM lets you adjust this down to "0%" but it seems autobrightness is a little buggy.
edit: nevermind. The range for autobrightness is 5-100 by default. When manually setting brightness, I believe "0" is possible on stock? I agree there are times a dimmer setting would do. Changing gamma settings can get you deeper colors and result in a dimmer looking display. Opposite of the graying you're referring to.

I'm wondering about this too, in bed at night the screen is too bright on the eyes which makes the reading time much less,
on amoled screens its great due to no backlight which doesn't make the eyes tired,
there must be a way to reduce the backlight, but it may make the backlight flicker if undervolted, which would be worse on the eyes

Have you tried playing with the gamma settings and dropping the brightness down to 0 manually (autobrightness only goes down to 5%).
Halfbreed is pretty decent and results in a "dimmer" display without washing/graying everything. Only problem is under daylight, it's not effectively as bright.

I'll try messing with the brightness and gamma settings. It's a shame there isn't a better alternative right now.
Maybe, in the future, a developer makes a kernel with this built in (if possible). Fingers crossed! :/

For what it's worth, I think you'll find 0% brightness and halfbreed to be exactly what you're looking for.

Download twilight and try it. It has an option to lower the screen brightness further...

Bumping my own thread:
I talked to the Nexus 7 (2012) kernel dev who managed to lower the panel minimum brightness, and he pointed me toward this:
https://github.com/CyanogenMod/lge-...ch/arm/mach-msm/lge/mako/board-mako-display.c
I'm hoping a Nexus 4 kernel dev will see this (or someone who knows what to do with it). He said it might be possible to do on our displays. Also, go check out M-Kernel if you still have a 2012 Nexus 7.

So, we just need to chance it and compile the kernel?

[Q] psychedelic screen in full sunlight...

Has anyone used their screen in full sunlight?
a few of us on the Australian Model (910G) has found that in full sunlight in any of the 4 modes the auto brightness seems to adjust the screen WAY up so that colours are washed out and the screen looks psychedelic.
Its utterly revolting.
is there any way to disable this OTHER than disabling auto brightness?
or is this a firmware bug?

Hey mate I have been in full sunlight a number of times and not noticed this at all. I would notice it as I am quite picky.

I can force it by a small LED torch as well (after about 30-40 seconds of steady bright light) It's not just me though At least two others I know have it as well...

I have something of the same... In the sunlight i can use it fine but when i put a shadow over it... it looks a bit weird in contrast with the part of the screen in the sunlight. I thought it would be something to do to make the screen better in the sun!

Under direct sunlight I can barely notice this, I have just tested at my work as the sun shines in through a window next to me. If I hold it under direct sunlight it does boost the saturation, but while it's under sunlight I can barely tell this has happened. When I take it away you can tell that it has boosted the saturation but it's not Psychedelic to me at all. So I believe my phone doesn't have this issue.

Its especially noticeable in games.. I'm a bit addicted to both Marvel Puzzle Quest and Ingress.. and you really *really* notice it in the former, the latter not as badly but its definitely there.

It is supposed to do this when Auto Brightness is enabled. The picture should answer some of your questions and better understand what exactly is taking place.

May be irrelevant but someone mentioned this to me last week and I suggested to change the "screen mode". It's default is adaptive and for some, is terrible at ruining colours in any light... I believe he changed it to "Basic" or try any other the other three choices and said it worked (for the most part).. Was less crazy anyways, I believe he said.. Worth a shot
