What's up with auto brightness? - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

I love this tablet! It's super fast, the battery life is great, and the s-pen features solidifies it in keeping it a next gen iPad killer! But I have one question. Is it me, or does it seem like the auto brightness is a little too dim for the screen most of the time? I find myself when playing games (mostly dark ones like Need for Speed Most Wanted) that I have to turn the auto brightness off and manually adjust it in order to see and keep up with the fast paced action that's going on. I also find myself doing this for movies as well & I wanted to see if any of you guys had similar issues.
PS, it works great when I'm in a bright area, as the auto adjust does its job correctly and crank the screen up, but I'm rarely outside with the tablet. It just seems like when I'm inside of a building the screen is entirely too dim
Thx,
Eddie

turn off the auto brightness and put it at 40%. Will be perfect. Auto brightness has issues.

[Q] Screen auto brightness frustrations

The screen auto brightness has always bothered me. I love the convenience of using it but it simply doesn't work like I believe it should.
For example. At night while laying in bed in a completely dark room I'd expect the screen to dim to it's lowest setting. When in actuality it does not, and it always seems to bright. On the other hand when I'm outside in direct sunlight I'd like for the brightness to be at 100%. Again this doesn't appear to be the case.
So what's the issue here? Is there a dev out there who has found a better solution?
I agree with you on this one. The automatic brightness on the EVO is just silly. Its lowest is 25%, by the way. There should be a way to choose what you want the minimum/maximum brightness to be :\
I've seen this question before, some time ago, but still no solution. I've seen someone say use total screen control trial (free in market) and tweak the filter settings to essentially do the dimming value you want.

I have been searching and searching for an answer to this. I don't want to have to use third party programs if I could just change the thresholds myself.
In Calkulins rom he says he lowered the maximum auto brightness to save on battery, and this question has been asked there, with no answer (except for the usual "just use this program to do it").
Someone has to know where the settings for this are. I'm getting more advanced at dealing with apk's, jars, etc... But I haven't been able to find which one controls this. Build.prop has some brightness settings in it, but it's just the default setting when not using auto-brightness (I think).
Anybody ?!?!?!?!?!?!?!?!?
I know it's possible, because Cyanogenmod has the option to tweak the levels in CM Settings.
I just know I've seen an app here on xda, but don't remember what it was.

I know it must be here too but but searching comes up with nothing new. I've tried autobrightness, auto-brightness, with min and max levels, thresholds, custom settings and every other search I could think of.
Maybe I'm leaving out the one keyword that would finnd it... lol

Thanks for looking, but unfortunately I've been there already. It basically allows you to toggle between auto brightness and a variety of static levels, but doesn't affect the min and max of auto brightness when you are in that mode.
I'm trying to be able to leave the phone in auto brightness mode all the time and just have the screen get to it's max available brightness when I'm in a bright area, and minimum available brightness in a dark area.

I did a quick search too, but I couldn't come up with what I saw before. I remember thinking "neat, but I don't need that because it's built into the Rom". It's driving me nuts now too :/
You could always contact one of the devs from CM & find out what files need to be edited.
Basically it sucks. It actually drives to crazy so I just don't use it anymore. When I am on tapa I put the background to black so it's a bit easier on the eyes when I am laying in bed going through the forums before sleep

How to lower brigthness even further?

I was wondering if there is anyway to lower the brightness of the display even further than the lowest setting on Andriod. I realized I used the phone a lot in the dark ( i take long walks at night) and the lowest setting is still too bright for my eyes.
Anyone know an app or someway of lowering the brightness even further?
thanks in advance.

[Q][USA][GSM]Any way to turn off "dynamic contrast"?

Hello all,
I've been poking and prodding my new USA GSM Galaxy Nexus all day and I noticed something: the screen seems to have a dynamic contrast function, similar to that of new TVs. I would like to turn this function off, although I don't see anything in the stock ROM to do this.
NOTE: I AM NOT TALKING ABOUT "AUTOMATIC BRIGHTNESS".
I want to see if anyone else can reproduce this or if it's just me.
Turn off "Automatic brightness"
Set your phone to 100% brightness.
Hold your Galaxy Nexus in portrait mode.
Go to this page in your browser on your Galaxy Nexus:
http://www.samsung.com/us/
(make sure to request the desktop site and not the mobile site in your browser of choice)
Scroll down to the bottom of the page and zoom into the black section with all the links. Zoom in as far as you can. If you're using Chrome, the words "Who We Are" should go across the length of your screen.
Scroll your screen so the words "Who We Are" is at the top of the screen and no white background is present at the top of the screen. The lettering should be pure white. Remember where they are.
Slowly scroll the page up by swiping your finger down the screen so that you gradually see more of the white background and less of the black background until the black background completely disappears off the bottom of the screen.
Swipe back up so that the words "Who We Are" are in the same vertical position they were in Step 6.
Repeat steps 6-8 multiple times at a faster rate. As you keep scrolling, watch the brightness of the screen and/or the whiteness of the words "Who We Are". When you first start to see white, the white will be white, but when more white starts to take over the screen, the phone switches to a less-intense white. (I'm assuming to save battery)
Is anyone else experiencing this?
download supercurio's voodoo mod sequel, the displayexpert beta in the voodomods forum. there is an option to turn off the dynamic brightness limiter. works perfectly!
This comes up once in a while, and many people say they see this issue. But I just can't see it! The sgs2 has the option to turn this off, but nexus doesn't.
Is this available in the kernel code to view and tweak,or is it closed?

Are you considering adding this into AOSP and letting Google know, or just tweaking/adding to other custom ROMs? Or just curious?

I'm not really a dev in any sense, but would like to see if this function is in the kernel and not hidden. If its not hidden then I'd imagine someone would have added an on/off option by now. So I'm not the person to handle this. My ability is at most compiling my own kernel with a little code change, at most, unfortunately.
Yeah. There is some kind of brightness limiter like plasmas have it too to meet energy star standards. Its a lot less noticeable on a phone screen and probably helps with power management. It can be a bummer on plasma watching hockey or movies like ice age. I would gather there is a way to tweak it. On plasma, no go.
teach a man to fish, you feed him for life. teach a man to fastboot, and you create competency. and less threads on xda.

Hmmm? I have an LG plasma TV and I can turn off all the dynamic stuff fine. It's in an Advanced menu on my TV.

all plasmas can turn off dynamic whatever. i am referring to what is called auto brightness limiter aka ABL. i know samsung and panasonic utilize it in their plasmas. no way to tweak it. there is something similar with samsung phones with amoled. bright images get toned down because all the white/brightness suck a lot of juice. i don't know if it can be tweaked on phones, but i think it can somehow.

Minimum brightness still too bright

Any idea how I can reduce the brightness level below the minimum? When reading in bed for instance, I find the setting to be too bright. I don’t have any other reference [FONT=&quot]than my iPhone 4 which which has a greater range – e.g. the max brightness is roughly the same but the min brightness is much less than my Galaxy Nexus.[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]Any suggestions are much appreciated. Still on 4.2.2 but will upgrade to 4.3 when Wug’s[/FONT] Root Toolkit is updated.
I have always used Lux Auto Brightness app. There are other options though.

You can try with screen filter

Screen Filter works good if you are using your mobile at night
Great, thanks! I'll try those two apps.
Will give screen filter a try

Find it really helps when using before bed with eye strain and bonus helps me fall a sleep quicker.

I use this on my N7. Good app. I wish they'd put a scheduling ability in to it so you could have it automatically turn on and off based on time.

It has a tasker/locale plug-in built in so you can do that if you own either of those two.

I have tasker but have found its scheduling extremely unreliable. It will randomly turn the screen filter on and off over the course of even just 1 hour. It is super annoying to be reading something then all of the sudden the screen kick back to normal brightness and burn your eyes out.

You can use a task in Tasker to trigger a full screen scene overlay that acheives the same effect as screen filter. It's much more reliable and only uses one app!

Auto Brightness Issue

When I turn on auto brightness it goes almost completely dark. And it doesn't adjust, whatsoever, after. Any one experiencing the same issue? Is mine broke?

I certainly don't have that problem. You don't somehow have the sensor covered right (not that I know where it is)? I would exchange it if not.
Where is the sensor?

For free you could try Lux Lite which is an auto brightness replacement. At least you will know if the problem is hardware related.

That app is fantastic. That's the way my auto brightness should be working! So I guess I do have a hardware problem huh.

Not so sure you have a hardware problem as both the stock autobrightness and Lux Lite use the same sensor to determining when the brightness requires adjustments. So I'm not sure what's going on. Well at least you have an alternative while you figure out what is really going on.
I bought this from Amazon. How long do I have to return/exchange a tablet?

The auto brightness on the S tabs is useless. I think what happened is that they simply used the algorithm for brightness adjustment from the Galaxy phones but didn't adjust them to compensate for how dim the AMOLED panels on these new tablets go in comparison. Lux's adjustment actually works and I really like the app because it's one of the few that finally show you the actual brightness percentage.

After trying the free version I purchased the pro version. What I found is that I used two different profiles, the regular "Auto" (Day/Night) for indoors and "Cinema" for outdoors who's brightness is always higher the indoors. Swapping profiles is very easy. I even have a one brightness setting profile for watching videos with the lights off at night. So the pro version has been well worth it.

You are correct. That's how all of my Samsung devices work when enabled.
My auto brightness didn't even do anything. Didn't works since day one. When I turn it on.... it goes almost completely dark. It sucks.
I want to exchange it. But since I have 30 days with Amazon... I'm hoping the 32Ghz comes before I swap it.
Sm-t705, sm-t700
On the sm-t700 (WiFi) autobrightness works much better than on the sm-t705 (LTE-Version). I checked the hardware with CPU-Z and HW-Info apps.
The light sensor (type CM3323, Capella Microsystems) of the SM-t700 is rated max. 3000 Lux and the sensor of the t705 is rated up to 65000 Lux (type TMD3782 from AMS). I guess the algorithm or parameter settings are the same for both devices.... this might be why the prob is even worse on the 705.
!!! So if you respond to this thread always tell us which device you have !!!
- I am wondering if there is some kind of parameter file where the margins ... can be set (of course this would require root) ?
- I am anxious that an app like LUX would drain the battery more than the built in app ... what do you think ... ???

Drivers I'm sure are complied with kernel and parameters should be in source. Maybe also modification to ROM framework-res would also be needed. Remind me in a couple weeks time after I've updated the 8.4" kernel and released the 10.5" kernel. Maybe I'll have time to at least take a look.
Works just fine for mine.
