I've noticed kernels with the 65fps mod have a bug where the colors washout after turning the screen off then on the first time after booting.
Here's how to test it. First go to a dark room and put the screen brightness on a low setting with the power control widget. Second reboot your phone and go to the settings page, don't let the screen go off. Then look at the dark grey background and take a mental picture. Finally turn off then on the screen and look again at the background, it looks washed out and a lighter grey.
Can anyone confirm this? thanks.

its not a bug. your seeing a difference in the screen frequency. the normal screen frequency is 56Hz, to get 65fps the frequency is changed to 65Hz. those kernels that allow 65fps still boot up at 56Hz then change to 65Hz after the screen is turned off for a few seconds.

Oh OK, that makes sense.
To me it's not worth having the 9fps boost at the cost of having the colors washout. I don't think it's even noticeably unless you run quadrant benchmark and see the 65fps at the bottom of the planets test.

generally the fps difference isnt noticeable unless its on a high fps game. but its not always better to have the higher fps, sometimes youll even notice "skips" at 65fps, depending on how the game was written. but there are a few(not many at all) games/apps that i have noticed a difference, for the better, with more fps. but the colors dont actually wash out, thats the normal colors before the color drivers kick in. you just dont notice it at the normal fps.

The phone actually boots at 50Hz then switches to 56Hz or 65Hz as specified.
The washing out is why I tune the gamma to be punchy.
pay close attention, you will notice it at 56Hz too .
this is more a "not 50Hz bug".
lowering your Hz may allow you to keep vsync longer , but if not, you get hit with 25fps spots in games.
with 65, you will get "33"fps spots.
hope this helps.

That helps a lot, I can notice there's also is washing out at 56fps.
So how would you go about changing the fps to 50? I know in mach-herring.c setting the freq to 60 gives you 56fps and 72 gives you 65fps.

Please add the option of modifying auto-brightness levels, like CM 6.1. I suppose that it would require a kernel modification + an app to do this through gui.
Thanks.
What can CM do? I've been thinking it would be nice to be able to modify the min and max, and maybe the curve.

It allows one to arbitrarily edit a table of sensor output vs brightness/button brightness.
It's really nifty.
CM6.1 reports these sensor values:
10, 160, 225, 320, 640, 1280, 2600, 10240
10-160 is in dimly lit indoors, 320-640-1280, in moderately to brightly lit indoors, and the rest is outside.
So I set those to brightness something like 50,60,70,80, 110, 140, 180, 255. A it was perfect to my eye. Not too bright, not too dim.
Didn't ever have to mess with brightness after that.
I'd really like to hear from developers like Netarchy and King, as well as from regular users - if they would like that option.
I would love to see this.
I always feel the auto-sensor tends to be too bright, and never adjusts the screen low enough inside.

That's exactly what I think. Plus, the brightness is not at maximum in direct sunlight (although that might be a safety feature).
Mine always send to bright, or it won't get bright when I go into a bright area until I sleep and wake it. :|

The stock auto-brightness is way too bright in completely darkness. This is one of the things I had on my list nearly since the beginning. Nobody else seemed to care.

Pretty sure people have given up on this. It's taken me three days of Google searching to find this thread so people probably don't know where to turn.
The lack of adjustments to the auto brightness values is extremely annoying. Even my old Windows mobile 6 phones had this ability.

There was an application for WM I used to use on my Mogul, cant remember what it was called but it allowed you to calibrate the auto brightness levels. Anyone know what I'm talking about, or if there's an Android version?
This can be done with Tasker in the Market. Its a powerful app and there was a thread a while back about this exact thing. I don't remember what it was called, but I posted in it, so you could browse my posts from a month or so ago.

It sure is quite a bit darker! Makes it a lot better for reading at night since the lowest setting is very bright when you are in a totally dark room.
Even if it's just a filter, when a pixel on the AMOLED if dark(black) it's OFF not displaying black. If the filter can make the screen put out less light, it must reason that it's using less power. You can tell that the screen even with a white picture is hardly putting out any radiant light with the "filter" applied.
The battery life is already really good on the lowest setting, so I'm not trying to save power. But if I want to check my phone while i'm in the theater, I don't want to blind the people behind me/disturb them. So it's great for that.
Try Rocket Rom. It does both things you are asking for.

This screen has no LCD backlight. It's an AMOLED screen, which means each subpixel is its own light source. Therefore, the screen "filter", which causes everything to be dimmer, does, indeed save battery.
Ok, so I have spent the last few days tweaking the auto brightness settings.
My goal was to have the screen at the dimmest level at just about all lighting conditions, and to not have to strain to see things on the screen. In doing so I also altered settings to the sensor filter and scan timing to make it a small bit snapper. I needed to do this because sometimes I unlocked the phone to a screen so dark I could not tell it was on, and it took too long to adjust. Now it is pretty snappy. I took all my samples from many light situations, however there are situations where you may be directly under a light and at a angle where you have glare. I made no compensation for glare, and find no need to as it's very rare for me.
My goals were power savings and usability. I don't care about colors. if I want better color and I'm going to be using in a dark room I'll turn auto off for a bit. But I honestly don't find them that bad and like a dim screen in bed at night..

I second this. I've been on these settings for a few days now, and I haven't had to touch the manual settings. I think it's safe to say I'm an auto brightness guy now.
I still use manual when I'm indoors like in school where I just leave it all the way down because lighting is consistent, but I leave auto on the rest of the time.

That's a great setting for autobrightness. But i think its not good for battery life.. too many levels will cause the system works hard for changing the display. Im currently on 7 levels, it gives me a great battery life. I'll try this and report, maybe my thought was wrong...

Those are not settings, those are a read out of values of the sensor. What you need to adjust is the grey boxes... And your readings of -1 simply means your auto brightness is turned off.

You could have a thousand levels and it would not make a difference.
What would make a miniscule difference is sampling rate.. But you turn that up to high and your going to start feeling very impatient when light around you changes and your screen takes forever to reflect the changes.
And you won't be saving much of anything by doing do.
Example:
Walk indoors from the bright outdoors, your screen takes 10 seconds to turn down from max brightness. You just wasted more battery with your screen in those 10 seconds than you were trying to save by turning sampling time up.
Our screen is our biggest battery killer
Sent from my SCH-I500 using xda premium
I still get about two days of life on the stock battery with these settings. Like neh4pres said, the screen is the real killer. There are also a lot of other tips and tricks out there to get the most out of battery life. In the end, I can't imagine my sampling rate is making any significant difference, and I love watching the screen quickly and smoothly ramp up when I step outside.
I just tried these values....its too dark for me but I like the consistency. I would like to try some slightly brighter values but I am not sure how this works. Can anyone give me some suggestions ?

At the top of the screen where you start the settings it shows what light level your on at that second. if it's to dark at that moment adjust the corresponding level and hit apply to see the difference..

Ok using the values from the OP, currently I am on Screen 11 and its a little too dim for me. What value do I change now? If I unlock screen its on #9 and dim as well..
It's not that bad really just after unlocking there is a heavy blue/purplish tint which goes away in few seconds as the screen brightens but if I could keep it like this only slightly brighter that would work. I don't really know which value I'm supposed to change..
In the meantime I found a nice compromise, I'm using:
Window length: 5sec
Reset threshold 400Lux
Sample interval 2sec
Screen Dim Level @ 20(default)
With the default levels and it seems to be working well so far. I'll know later tonight when I'm listening to beats in the dark.

Screen dim level set to 1. Then it's the values that are different in the pictures, the middle ones. Those are the brightness values. The first 2 numbers on the left are the light levels that would enable that level.

Good idea. Thanks again. Some one already started a thread about it so I added it there.
It has been recently looked at and i think it's pretty mature already.
The idea is that most of us have had to rely on third party apps, such as lux auto brightness, to be able to control this feature, because the built in was not properly coded or adjusted.
I want to open this thread to ask for the people's experiences: which configuration are they using and if we can really kiss lux goodbye for once.
Not that I am unhappy with this software, but I don't like using external apps when the functionality is integrated (thus saving resources, etc, etc)
Thanks for your impressions and i hope this thread is helpful.

There's a fair amount of discussion on this in the CM9 thread. Anyway, the HAL now reports lux values from the sensor in values other than powers of 10 so I'm fairly sure it will work. There is still some debate on what the default brightness levels should be in the auto brightness settings but this is all customisable.
Never used lux myself but surely it can't have worked any better than the closed source HAL did because no matter what averaging it does on the data limiting to powers of 10 severely restricts the quality results you can get?
Thanks for the reply.
I know there is some info in the CM9 nightly thread but it kind of gets messed up and buried... That's why I wanted to isolate and study the case here....
Which would be the correct configurations? Or we can just enable it and leave it by default?
Cheers

Well I've seen NOWE has done a lot of testing with the custom levels as only certain intervals actually result in a noticeable brightness change.
You can search for his posts in the thread: http://forum.xda-developers.com/search.php?searchid=44763856
I'm using default levels at the minute with averaging and a 400 lux reset threshold and 10 second averaging window. Also, I have "Allow light decrease" on and a 50% decrease hysteresis. These are settings I picked up from another user in the thread.
I'm hoping if the custom levels (NOWE or otherwise) are better than the ones currently in the build then they'll get pushed to source and I'll get them that way..
Glad to see this thread opened up as this issue is honestly the only thing keeping me from using cm9 now. The big issue for me is the 10 second window the lux values are being refreshed at. Compared to the default 5 seconds on a Sammy rom it feels like it takes an eternity to register changes in light conditions.
This honestly doesn't seem like it would be that hard to fix, so why is nobody talking about it? Now that the sensors are functioning properly the only thing that needs changed for perfect auto brightness is for the sensor refresh rate to be changed from 10 seconds to 5.
Test it yourself, open the custom auto brightness levels window and watch the sensor values change. Start in a bright area and put your thumb over the sensor. You can count to 10 before any change occurs.

The values 15, 55 and 80 are redundant. (1...29=GAMMA_30CD, 30...69=GAMMA_40CD, 70...89=GAMMA_70CD)
Entropy512 said that it is difficult to make more steps, but I sill have the slight hope that some day we will have these steps.
(GAMMA_15CD, GAMMA_55CD and GAMMA_80CD or something like that)
So atm the brightness jumps a little bit in the lower range because the steps are too big.

This is a solution I've seen people throwing around but in fact it only makes the screen adjust even slower.
By adding a filter you are essentially averaging the lux levels being reported and smoothing the gap between jumps. Adding a filter does not effect how often the sensor is reporting data. But by smoothing over the jumps from say, moving from a dark room to outside, it makes the screen brighten gradually rather than going straight to max brightness in one jarring step.
I may have exaggerated slightly by saying 10 seconds. Its more like 7-8. But no fiddling with filter settings is going to change that the light sensor is not reporting data frequently enough. Or am I the only one who feels it is too slow? It drives me nuts and is the sole reason I'm sticking with Sammy roms atm.

Ok I have to agree with you, I am now beginning to understand how this whole light sensor/filtering works.
For example:
W/out filter 20 ------------ 80
With filter: 20 --35 -- 55 -- 80
It is taking the same amount of time to go from 20 to 80, only filtering will make the transition smoother, not faster.

The only time I've seen this happen since I've gotten the device is when the battery dropped below 5%, and it automatically adjusted the brightness to seemingly the lowest it could go, and stuck until I charged it to full again.
I blame it on Samsung's stockware.
maybe this is why i couldnt get the phone to look as bright as my note 2. i was using the browser and cnn.com to compare.. my note 2 screen was brighter with both phones brightness on max.

Just throwing this out there...the screen does dim about 10 seconds before the screen times out and turns off...even if you have automatic brightness disabled.
Let's say you have a 1 minute timeout:
Screen on
50 seconds later screen dims
10 seconds later screen turns off
Just putting that out there in case - it is confusing to some.
Dude I'm having the same problem, yeah it's a small dim but it's freaking annoying cuz I have mine at full brightness all the time. I have the tmobile galaxy s4. I tried changing the screen mode and it still happens

I've noticed it too. Just seems like typical dynamic contrast behavior. Though I don't understand why on earth you'd need it on a screen with perfect blacks.

Well this never happened on my S2 or S3. And i just saw a thread like this open in the tmobile forums. It really annoys the hell out of me

I'm sure it has to do with preventing burn in. You probably already know this, but in the right conditions, the Auto brightness setting can get over 30% brighter than manually maxing the slider. Hopefully, it's something that can be unlocked at some point.

I got my Galaxy S4 yesterday and noticed even after i turned auto brightness off, Set my screen to dynamic, the screen still changes brightness levels when entering the Chrome web browser (gets dimmer), playing some video games (screen get brighter) and other various tasks.
I am not a noob, I've gone through the phones settings for each app and cannot find a fix, do you guys notice your phones doing the same thing?? I might be a slight change in brightness level but non the less i like my screen extremely bright this is just my preference.
Any thoughts, ideas, tweaks or feedback on how to resolve this issue??

I don;t know if this helps or not....i notice the same thing earlier.....what i did was go to Settings--> Display, uncheck Auto Adjust ScreenTone
at least that is what worked for me
Maybe the power saving mode is manipulating it?

Its the power saving option. Its the same in s3. Go to powrr saving settjngs and uncheck the auto dim or auto brightness or something like that. It happens when power saving is on. I cant remember the exact optin coz im using custom rom on my s3.

This happened in the S4s I used in the store as well. Manual brightness, and auto screen adjust disabled, power save off. Opening certain apps like chrome and the stock browser causes the screen to dim a bit. Nothing I found prevented this behavior. It's annoying since I already find the screen to be a bit dim.

Notice this as well, super annoying. I've disabled power saving, auto screen adjust, etc. and even non-dynamic modes do it.
Hopefully this gets fixed by kernel mods in the future
Same problem, even with brightness max with auto off, decent charge, and off power saver. Very annoying

Its built into the Snapdragon, its called BRITE and seems works independantly of the auto screen tuning that the S4 has. The HTC One has it and its much more intrusive. I wrote a long winded post about it in the HTC One forums. You have to wait for devs to come out with kernels to disable it, much like they did for the Tegra 3
The HTC screen is bright enough that it doesn't matter. Samsung phones need to be at max brightness to be any good.

Just an FYI, if you put the screen on auto brightness, it reaches a higher maximum brightness outdoors as apposed to the slider. Samsung did this to keep the screen from overheating when set to max all the time.
I want full brightness indoors too.

I see. If you have the slider on max all the time, i think the screen will just dim eventually because of heat. Might want to stay away from the S4 then cus you might have screen problems down the line :/
If you havent go to settings display screen mode and use something other than adapt display. No more adjusting.
