Is there any overhead with this type of thing that's not kernel based?

LG is oversaturating on this display(don't ask me or question my decision, I've seen the gamut) and I believe it's best to leave it at stock except you want the washed out nexus 4 default colors.

While I don't disagree, for some reason the S4's screen is still easier on my eyes than the G2's. (and I'm not coming directly from an S4) Maybe the G2's auto-brightness is just leaning towards being too dim, or maybe over-saturating a LCD screen looks worse than an over-saturated AMOLED screen, or maybe it's simply the text that the G2 uses... I don't know what it is, but I'm finding the G2's screen doesn't feel as nice to my eyes as the S4's. I know, I'm probably crazy...

I'm not going to argue here but when I do lay out information I know what I mean.I did a test and this reviewer did it too.They r the same!LG is oversaturating.Watch this before saying what not.Samsung doesn't over saturate.Their displays are produced like that by default and have a wide gamut.But they seem to be correcting that with the s4.

I can tell you what it is.. it's the glass and LCD combo they use. it's weird on the eyes. it's very reflective and can almost get a weird rainbow effect, and it has bad angle viewing.
this screen is almost identical to my rezound.. amazing screen but it had that weird glossy effect to it. the dna however was a diff type of screen apparently bc it didn't resemble that at all... and now the g2 does again.
basically it's hard to explain but htc uses a screen very similar to this in the rezound which is reflective and glossy whereas in the dna and one they switched to some different type. maybe it's the glass? idk. but the g2 does have a diff type of LCD screen to it.

also idk how you can say the s4 isn't over saturated. I have to set it down to the standard or photo screen setting bc their stock is the dynamic one that's super saturated.

If you don't want people to ask you why you've come to this conclusion or to even have the audacity to question your decision, then perhaps you're better off not posting something at all. Talk about a terrible post, essentially you say "Do what I tell you, and don't ask why".

You can see here that while the G2 display covers sRGB space nicely, LG have pushed the saturation on R, G, and B values. For instance, look at the two dots at the bottom in Blue. The next to last dot should be in the next to last square for accuracy. Instead, as R, G, and B values approach maximum saturation, the color approaches full saturation too quickly. Hard to explain but stare at the chart for awhile and you will understand :fingers-crossed:

Actually not hard to understand if you understand photography,
But from the chart you can see that the colors are also shifted in ways that will make the screen look strange or skin tones maybe too green or red.
So not only does it saturate too quickly but the colors are shifted.

I don't know why some keep arguing.I own a G2 and we r on the same side.I'm stating the facts and they r as clear as the fact that LG made this phone(or is it made by Apple?).That's y I say don't question the proofs of over saturation I laid before.The picture above is crystal clear!

Um, yeah. The screen looks just fine to me. I really don't care what charts say, I'm sitting here with my g2 next an s4 and the g2 looks less "cartoony" so I'm fine with it. I just thought I would mention that color calibration was available, not to start a lecture on color saturation.

I understand and I'm not arguing with you, I just think the delivery could have been a bit better. You could have at least left it open to foster a discussion, and not been so dismissive to people who might have questions about your conclusion. That's all I was getting at.

Maybe I am a saturation sucker but I did like the colors on my S4, seemed to pop on there.. not so much on the G2, its lighter

Took me a while to get used to the LG screens when I first got my Nexus 4. I actually prefer them now to the S4 and the One. One thing I really like is that there is pretty much no space between the glass and the screen. I think it will grow on you. The screen looks brilliant with video and colorful backgrounds, etc.

CHeers,
This is amazing. Been wanting something like this 4EVA!
Would this save battery by any chance?
Sent from the almighty Vibrant!!!
LOL u guys must be old.. or vampires... I love the amoled brightness....
This is so great, I can use my phone at night now! Just need a scheduler to turn it on past midnight hehe
hows battery life with this???
Re: Posts pertaining to battery life.
*I use this app exclusively at night with all the lights off. meaning, I'm vampiring playing Angry Birds, NOT SLEEPING. LOL Hahahaha... I should be in bed.
Conclusory: I am IN BED !!! It's just that I'm not sleeping.
I know, i know... long winded answer to your question.
The bottom line is this-> I don't have the screen filter on enough to know whether it makes a difference in battery life. My guess* is that YES it does make a difference. The reflective light that is emitted from the screen is a lot dimmer when the app is ON.
Common sense would say : Yes this app does save battery. I only say yes (cautiously) because our SAMOLED screens are not conventional Emissive LCDs whereby light is shown from behind it. Each pixel is in fact turned On/Off. So having a resulting dimmer screen than the factory pre-set at the lowest setting leads me to believe that the pixels are emitting lower levels of light. This is of course, just a conjecture.
So, my ultimate answer is: Why not just try it out and see if you like it/helps you/reduces battery usage?
Answer may not be satisfactory to your liking, but what do you have to lose? Just try it out.
Cheers.
*Sigh* caught me again. Yah, you can call me grampy. I get it all the time.

This is excellent. First brightness app that actually works in the browser! And I think I've tried them all.
Me too. Me too!!! I was about ready to wear sunglasses while going to sleep. I have this really nice pair that I get from my eye doctor (I'm older than she is). It's a roll-up style piece of plastic that just sits on your eyes. It is an excellent product for people coming out of full blown eye exams that require pupil dilation.
Yeah* I know. Hey, I'm old school. What can I say. *(puaha more like "old fool")
But it works.
But good thing I found this.

Thanks for the tip. I'd rather have the option to change on the fly though. Auto anything just bothers me when there's so much interaction with apps/games/schedules/emails/ the list goes on. But thank you nonetheless.
Haha. Fruit Rollup sunglasses. Great production like I said. Thing is, I know a little about plastics and coatings. Most of the technology behind optical correction lenses is premised under the theory that the lenses are rigid. Having other materials/coatings/technology in rollup lenses doesn't seem to be workable without serious degradation to optical clarity or longevity.
But I will be on the lookout. If I find anything, I will let you know.
On a sidenote. Don't threadjack!!! Okay, okay, I concede, I brought up the pictures first, so I am to blame.

Wow, you guys must never get eye exams. Those are given away for free after getting dilated. I get one everytime I go in for an eye exam and just throw them away after using it. They are pretty ****ty and pretty ugly, and they announce to the whole world "hey I just got an eye exam."
They have been around for years.

Yup, these are what I usually get at the nicer optometrists. Haven't gotten anything but a "good luck" from any Lenscrafters.
Finals has my sleep schedule completely flipped the past week so I've been using this app nonstop at night and can attest that under Settings>About Phone>Battery Usage the display has been using a smaller portion of my battery than before, but not by much (~85% to 80% with filter at ~50%).
There is an issue inherent to OLED screens (I think). Banding becomes very apparent at lower brightness, which I believe is because the diode is then set to display a smaller range of shades since this range may be tied to brightness. This isn't an issue with LCDs as the panel in them would not be affected by brightness, which is supplied by a white LED underneath the panel.
Fortunately, that's a compromise I'm willing to make for nighttime use. Does anyone know of a way to lower the brightness on the capacitive buttons? They're a LOT brighter than the screen at the setting I use. I could even stand to turn them off completely. Doubt any Vibrant user would forget where/what the buttons are after a day of use.

I only have screen bleeding issue when screen isn't on full brightness. Doesn't really bother me.
I posted this in another thread, but I took some pictures of the "screen bleed" (light from the buttons bleeding over into the screen) on my Amaze 4G. I also put up some pictures of my Nexus S, which has the same button configuration, but zero screen bleed:

Hokay, I added more pics to my album. Sorry about the terrible shakycam, I don't have a tripod or anything, and flash screws everything up.
Here's the two side-by-side. One thing I noticed: the Nexus is absolutely fantastic at preserving the blacks. I'm sure this is due to a difference in backlight/screen tech, but it's really impressive - black is just black on the Nexus. The Amaze is much lighter grey when it's supposed to be "black". Here's the two side-by-side with the backlights at their lowest and highest settings:
But even without any backlight or bottom lights, the Nexus' screen is still noticeably blacker than the Amaze. I also added another picture I found elsewhere on the web with two versions of the Nexus S - it is just a difference in the screen tech (SuperLCD vs AMOLED). That may be a factor here as well.
I'm not trying to discredit the Amaze at all - I own it, I love it, and I plan on keeping it. The screen bleed is probably made worse/more noticeable by the screen tech choice, which isn't as good at reproducing blacks. This isn't a huge issue for me, but I just wanted to document the differences here. I'm just taking the best pictures I can to represent it - it really is noticeable in person too, if you care about such things.
Can you take pictures in normal daylight on it's auto light settings to show how it looks in real life..

Wow, indeed. I didn't think the blacks would be so different on the two phones (which is why I thought it came from your pictures - evidently I was wrong).
Those pictures are awesome and clearly show how the bottom lights affect the screen, thanks!
Not enough to make me reconsider (though maybe I'll change my mind when I finally have it in hands).
My friend had a very similar light bleeding in his EVO...one day he broke the screen and when replaced with a new one, the problem was gone. so it was a manufacturing issue on the first screen.

Hokay. I've added some outdoor pictures, and a set of indoor pictures in my dark apartment now that it's day. Updated link. It definitely is much less noticeable outside (although I spend a considerable amount of time inside that I count as "real life" as well ), and the Nexus screen is still blacker, although not as much.

Yeah, the side-by-side Nexus pic I found really demonstrates that. It's not nearly as disparate outdoors, but indoors it's pretty noticeable. And it is just the screen tech - screen techs have their pros and cons, black reproduction is only one aspect of screen quality.

All the LEDs are capable of being dimmed, you just have to give them less power.

Not terribly on-topic, but LEDs are generally actually dimmed via pulse-width modulation - basically, if you want 50% brightness, you turn them on for 50% of the time, off 50% of the time, at >60Hz. Among other things, LED color depends on current - so supplying less current would not only make them dimmer, but change the color.

TFP's screen colour intensity

My main complaint with the screen is that last 2 out of 4 TFP's I had had washed out colours. Yes, there is a thread in regards to colours, but I want to take slightly different approach.
On Sensation, if you run command "dmesg" without brackets it brought load of info, including PANEL_ID_PYD.... Which gave you type of the screen. Since I had 50/50 good/bad screens, I wonder if we have different screens being shipped with TFP. Unfortunately, that command doesn't bring up anything like that, so question is, how to check screen manufacturer.
Now, I bet 100% that some of you have it and don't even know about it. My family thinks I'm mad, but being an amateur photographer made me see colours a bit more than your average person. So, even if you don't think your colours washed out, please check it and let me know your findings.
See this picture.

from the reports on this forum there definitely seems to be a lot of variation in the calibration of the tf201 screens that have been shipping. people who care about color and have gone through multiple units have observed that one is warm, another cool, another washed out... putting color tests up side-by-side against my HP ZR30w (S-IPS) and samsung GSII (super AMOLED plus), my tf201 is definitely a bit too warm and it doesn't have the best gamut compared to high end displays. but that's not really fair because both of these screens are more expensive and higher quality than what the tf201 is spec'd out to be. imo the tf201 screen is still very nice compared to other tablets out there so i'm fine with it.
Thanks for the input. I don't mind it to be on a warm side, but I like my red to be RED, not pale red. Same goes for blue. These seem to be most affected colours.
Anyone else?

The colors on my screen aren't even consistent lol
If I manually set my brightness, sometimes I'll unlock the screen to find deep, vibrant colors, and other times I'll unlock it to greens that I can barely see and reds that are nearly a shade of dark pink...
I personally believe that aside from actual individual defects of these screens, that ICS is at least partially to blame.
Anyone still on Honeycomb who can check this out? I swear I can't find a pattern to what causes them to look good or washed out, but I never know which I'll get. Reboot generally comes up to good colors (haven't noticed otherwise anyway)
I can tell you. Watch MAPS icon carefully, switch to battery mode, then back to normal or performance and watch the magic happen. Then lock and unlock screen to find normal-ish colours again.

But I never take it off the battery-saver. Ever. And my colors still get tweaked (although that explains lack of issue on boot up) sporadically. This is what I assumed it was at first, and may play a part, but isn't (in my case at least) the whole story...

battery saver mode definitely degrades display quality, wouldn't be surprised to find that it induces color shifts as well. run balanced mode for a while and see if you still have the problem.
Actually, in my case saver mode gives more accurate colours than two others. Did you do the test I mentioned in op ?

lol, I got one of those colorblind tests. Looks warmer on the TFP than on my phone.
Lol, I guess I'll have to upload that particular picture. Just find one with all the colours on it.
Btw, I hope Google search is not tailored to you, if it is you should see an eye specialist.

Lol, I ran that "test" just by looking at home screens, then inside the market the first day of owning. All you really need to look at is your market, then look at the green, orange, blue, and red rectangles for the different sections. My tablet is ICE compared to my HTC Vision. I mean, almost looks like different pallets entirely.

Yes, this is the exact problem I had. My colors were good until the .33 update. Now it is washed out. I returned it for another one and it is just as bad. I guess I got unlucky twice. I wonder if theres a firmware/software update for this issue. My HTC thunderbolt looks a lot better

This is why I think it is an issue of software more than anything. I do know that screens by default will be cooler or warmer than another; my identical LG LED monitors are just the slightest bit different. But the issue with washing out is something I did not notice in the few hours I was able to use my Prime and root it before it updated.
Yes, some will be slightly "defective," but I'm waiting for this next update and some homebrew'in ROM love after the unlocker. Then we'll truly see what's going on.
It's not as noticeable as it really is, dig?
I think it's clearest on magenta there, this is on Performance and SuperIPS.
The reason I'm doing it that way is that the picture is aweful without the SuperIPS on, when side-by-side to my LED screens.
Power saving + SuperIPS. More noticeable, but still doesn't look as bad as it does on the naked eye

Your one is good, very good. I'll post mine in the evening.
Now to determine wherever it is sw problem, we need to see if all of primes are the same, and if they are not, do panels differ or not. If panels are different, then possibly it is software. If panels are identical, then we have same sw, same panel, different colours = bad screen.

You cant just compare the colors on two different devices and say its the primes screen. There isnt a single display/graphics card on the market that displays colors correctly uncalibrated, regardless of how much you paid for it. With most displays the colors will be affected by the luminance levels. Most people adjust their displays for higher contrast and more saturation than what is actually true which can make other devices look pale or washed out. Im a professional photographer and know all to well that you cant use and uncalibrated monitor/grahics card combination for color adjustment in the photos. Ive seen many people over the years blame their cameras or printers for bad colors in photos when in reality it was the fact that an uncalibrated monitor was used in post processing. I use Xrite colormunki calibration tools on my PC and printer to make sure that what you see is what you get and its all true colors. This solution uses an optical measuring device and sends color offest values to the grahics card and print drivers. Any color variations are defnitely a matter of drivers to the display and unfortunately there are no adjustments available on android tablets although Spyder did release an app for Ipads.
I understand where you are coming from. It's not realistic to expect everyone to have calibrated screen. And yes, colours will vary between computer screens.
I had 4 primes, so I do have something to compare it to. I didn't notice anything like that with the first two, but it was obvious with last two.
Also, I compared it to all devices I have, and every device outperformed prime in regards to colour reproduction, especially red and blue.
Could you check yours with colormunki or against your calibrated screen please?
I really hope it's down to software, but I can't afford to gamble £500 on it.
I had some prints done professionally and compared them to my screen, so my screen is fairly close to real colours.

The HTC one X. The one S screen is brighter but it's certainly not sharper than the GS3 and it's not better IMO. The gs3 has one of the best screens I have ever seen period. That's including tv's, tablets, computer monitors. I don't know what kind of special sauce Sammy used on it but it certainly looks nicer than the Galaxy Nexus screen even though on paper they're supposed to be extremely similar.

Nexus has a pentile matrix (SAMOLED screen) while I believe the S3 has a SAMOLED+ screen which means there are more subpixels and a sharper screen than the Nexus.

Negative. The SGS3 also has uses a pentile matrix sub array. Yet somehow even with a lower dpi they managed to make it look slightly sharper than the GNexus.

The G S III also has a bigger screen size, so its harder to detect. Though I agree, the screen is phenomenal with the brightness and the contrast and color depth.
the general consensus is that the One X slightly edges out the GS3, and of course apple's retina display is going to be superior to both of these (and smaller). but does it really matter?
my GS3 has a great screen. do i enjoy doing anything on my phone less because i don't have the best screen on the market? of course not. the GS3's screen does everything i need it do, and in my opinion does it very well.
...sorry to go off on a little tirade :silly: but seriously... GS3 is the best phone i have ever used by a wide margin..

Retina is just a fancy word for high dpi/ppi. And if that makes it better then the HTC Rezound has it trounced as it has more pixels per inch that the iphone. I think apple has lost serious ground when it comes to their screens. Not that theirs aren't good, but others have just caught up and surpassed it.
I have a sneaking suspicion that those of you who say the sgs3's display isn't bright enough simply haven't figured out how to toggle between the default auto-brightness and 100% brightness.
I leave mine at 100%, the automatic just doesn't do it for me.

Nope, I had my S3 next to an Evo 4GLTE and the Evo is significantly brighter. With 100% brightness, and even moreso on automatic. The blacks are blacker than Evo, but the whites are blue/grayish in comparison.
Also, holding my S3 next to my S2 with the same exact launcher, wallpaper, and icon arrangement, this is what I can say with absolute confidence: the S3 resolution rocks, the S2 contrast is far superior, and the S3 is still lacking in the brightness department. Icons look washed out but text is way sharper.
Definitely one x/evo got a r screen on resolution and sometimes colors(depending if you want more natural colors) I but I'm loving this screen I like black as wallpapers and themes as well and I'm loving this screen and the phone as well

The One X does have a nice screen, but the only thing it has over the S3 is it's little sharper. I have both, and I think the Amoled is just a better overall display. The contrast just makes this thing pop and a joy to look at. Because of the backlight and lack of contrast, I always felt the One X's display was somewhat lacking. This is coming from a guy that hates pentile displays!

I had the one x for a week and returned it to get the gs3. Ive had all galaxy S's and even tho some say that Sammy colors can be a bit over saturated I don't mind. Actually I think that's the reason the Sammy screens are so pleasant to look at. The only thing I believe the HOX screen is way better on than the gs3 is how great it looks in direct sunlight. Other than that I just missed Sammy touches

Nexus 10 Pre-Calibration Results

Here is the Nexus 10 Pre Calibration Results.
no post calibration due to lack of adjustments right now,so its not much to do than accept it.
i try to explain the results here
first Gamma: average 2.21
that is reference class but the problem here is that the line isnt flat.
it should be straight at 2.2
around 2.0 at the darks and 2.4 in the whites
that isnt that bad that i thought it should be
i was more into that the gamma was way lower, around 1.5
if everyone complains about washed out blacks then they are close to reference.
so stop crying and enjoy details in the dark scenes
i think most other OLED screens have much higher gamma for the darks just to get a fake contrast boost.
the problem then is that you loose details in dark scenes and get crushed blacks.
on the Nexus 10 we dont loose any details.
Next Color temp: 6784 Kelvin is great.
6500 is reference so its just a little bit to the blue side
GrayScale: thats the one that makes white where it should be white
i must say that the grayscale is reference!
Great work Samsung!
the only part that sails away is IRE10 that has to much blue and red in it but then IRE 10 is almost black and you
will not see the colors.
Contrast
Blacklevel is great at 25% brightness on the Nexsus 10
with that brightness(Y: 130= recommended brightness for LCD TVs) you get a contrast ratio of 814:1
average i must say but not bad
with higher brightness you loose blacklevel.
(i also measured the Contrast ratio at 50% brightness and its the same around 800:1
blacklevel at 50% brightness is higher Y: 0.300)
and so to the worst
Color Inaccuracy!
Bad Bad Work Samsung
the calibrator must have slept during the process
not much to say that blue isnt blue on the Nexus 10
165%!! to high brightness and to low saturation
the only colors that is close to reference is CYAN followed by YELLOW and RED.
the others has to low saturation.
Note: the White Dot in the middle is our Whites
and with the reference class grayscale that dot is almost in the box.
its the white dot that controls all other colors so if that is off all colors is off.
but that doenst make any sense here.
the colors should be better but they are not.
i think the main problem here is the Colour Gamut itself.
samsung have choosen the wrong colour gamut for the Nexus 10.
so the conclusion is that Gamma level isnt as bad as everyone thought
the bad thing here is the colors with its low saturation and wrong brightness.
A new "Wider" colour gamut can make this display world class.
Edit: to the Developers that searching for a gamma adjustment you can stop doing that
The Gamma Curve isnt the main problem.
if we are lucky samsung has several different colour gamuts hidden somewhere.
so thats what you should look for.
on my LED tv i have 5 different colour gamuts to choose from and they all get different CIE scores.
if there are several Gamuts hidden they should be named "Wide" "Standard" "EBU" "SMPTE" "BT709"
Edit2: or you could search for "Adobe RGB"
thats one gamut that should have been on the Nexus 10 from start.
Nexus 10 cant even use the full sRGB colorspace,we only get 75% of sRGB it and that is really bad.
i was just checking the colors on my Galaxy S2 and it uses the full Adobe RGB colors.
thats why all colors looks so vivid on most OLED screens
they are calibrated to the wider Adobe RGB Gamut.
info on all colorspaces used:
http://thehdrimage.com/color-managment-and-monitor-calibration/
you can see that you get way more colors with the Adobe RGB compared to the standard sRGB
Awesome, thank you

not working but as i got the tools i can do tests if someone comes up to something.
even if you got saturation controls you need a colormeter to get it right.

It has 95% of the sRGB gamut.
diff colors on diff models
I'm not sure if anyone has noticed this before, but I've had 3 different Nexus 10 models (with a 4th on the way; RMA) and I've noticed different color. 1 seemed very warm and whites looked silver-esque, and the others seemed picture perfect (to me). Too bad that I had to return the ones with good color because of other defects. Hopefully my next will have no issues, but if it doesn't, it will be my last.

it could be lightbleed that causes that.
the color from the lightbleed seems to be yellow so if you have alot of lightbleed you will get a yellow tone in the whites.

you should have that % on the N10 aswell.
but to bad that the calibrator got drunk that day
the strange thing is that you can see a line in the CIE chart
Blue/Magenta/Red are on the exact same line.
its just like the Gamut was cut there and not where the boxes are.
i think i found something in the "fimc_is_fw.bin" file under system/vendor/firmware
"R_SatThresh" : "Gr_SatThresh" :

that looks like 8bit and 16bit colors
we want 16bit so why has it a setting for 8bit?

what the hell is this ?
is there different saturations for strong/mild/scene ?
and what adjusts those?

For people that build ROMs like myself, that file is called a "proprietary", which means it is a prebuilt file (in this case a binary) that ROMs have to use to make the device work properly. More than likely you will not be able to feed any values to it. About the only option would be to hexedit the file to see if it can be manipulated.
thanks for the answer ktoonsez
so you where aware of the file already

Patrik,
Nice find, I wonder if you discuss you findings with a developer you has already created color control capability on rooted devices including the Nexus 7, which we may speed this investigation.
Product: Faux123 Kernel Enhancement Pro
Playstore: https://play.google.com/store/apps/...GwsMSwyLDEsImNvbS50ZWFta2FuZy5mYXV4Y2xvY2siXQ
The developer invites direct contact at: [email protected]

I hope this helps as I agree color calibration capabilities would be a major feature for many people who are willing to root.
i know who he is but he doesnt answer questions so i let it be
someone else can give him this info
