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
Can someone assist me with some instructions on how I can pull the necessary file to modify mentioned settings, then push it back. I've found other threads on this but nothing specifically for our device.
I'm just sayin!

1) I've already posted in Q&A a couple days ago and no response
2) I googled it before I posted the question in Q&A and in here, and nothing was specific to the Tmobile sgs2. Since it's a modding question I thought development would be an appropriate place, but if i've stepped out of line, then excuse my ignorance.
I'm just sayin!
Wish I knew lol...oh how I miss the features of CyanogenMod.
You can try this:

Although I wouldn't recommend copying over his framework-res.apk. I would do it from scratch using apk manager or something.
Not to mention the kernel has to support lower brightness values.

Thanks for the input. Basically I'd like to slightly raise the brightness under the lowest lighting conditions. Reason being, is to help mask the blobs while watching Netflix, YouTube, and other videos with a low lit environment.

On a Samsung T-Wizz ROM, this may be quite difficult to find. You can Tasker to do what you requested though.
Create a new profile that is activated whenever you launch one of the apps in question.
Have the profile turn off auto brightness and set the screen brightness to x.
Set the end-profile condition to when the apps is closed and the end profile action to set auto-brightness back on.
There is a root application that does this, Lux or something like that, I can't think of it off the top ofmy head right now.

Thanks, I'll first try to modify the framework-res.apk to see if I can get some results from that. If not, then this definitely sounds like a good workaround!

xperia z1 compact brightness change itslef even when i have turned off the auto brightness. for example, the brightness becomes dimmer when the overall display colour is dark or black colour and it becomes brighter when the ovrall display colour is white or bright colour. i mean im able to notice there is a slight change in display brightness when im viewing photo, watching videos or surfing inernet. the brightness just change itself even when i turn off the auto brightness. so is there any solution or is there anyone has same curcamstances?

if you're rooted you can disable it by changing the build.prop ro.qualcomm.cabl=1 to ro.qualcomm.cabl=0

I tried that, but the effect still appears. Any idea?
I've noticed the same issue, especially when browsing using Dolphin
Two ideas (which both may be totally wrong).
Does the phenomenon occur anywhere or only in certain apps? Some apps just ignore certain system settings and mess with the phone how they want or how is defined within the respective app settings (like switching to auto-brightness even when it is turned off in the android system settings). There seem to be some very basic points missing in the holy whatever-app-coding-styleguide for android: Options shall always be OPTIONAL and, in case of doubt (which is always), don't fcuk with stick to the system defaults ... but I'm running off the track here.
With auto-brightness turned-on, there may be some slight loop-back kind of behaviour in that a brighter screen also creates a brighter environment for the light sensor, thus, making the device turning up brightness even more. Things like that happen in control/measurement systems all the time (well, not really all the time, but they do happen). I've never seen it on my phone, though. So, this is a very very hypothetical hypothesis if I may say so.
Hi
I set ro.qualcomm.cabl to zero, and for me the irritating behavior went away., and unfortunately the irritating behavior is still there.
Thanks for the info!

That's strange because it's kernel related so changing the build.prop has no effect as already mentioned, which I can +1 to.

I'll look again just to make sure, there might have been a placebo effect...
I noticed the behavior in the kindle app. When reading white text on a black background the screen got brighter when there was a white chapter start image.

You are right, just placebo on my part, when duplicating the error case I noticed it in, the CABL is still there.
I really really wanted it to work though, that must count for something... :-/

From google I got cabl=content adaptive backlight and it is intended for changing backlight change.. But what is its advantage?? Is it battery saver or battery eater??
Sent from my Xperia Z1 Compact (D5503)
Was searching for a solution to this 'feature', especially on a sunny day it is very annoying. Could it be that is has something to do with the BRAVIA engine? Just a thought..
so?
So this problem is kernel-related issue?
Is there any kernel that have fixed this?
Any soulution? It is super annoying
I have same problem. Any solution?
CM11
Thank you
I know this is for z1c, but I just got my hands on a z1 c6903 and it seems to do this a lot and fade on dark colours. I read that on 4.2.2 there used to be an optimized backlight option and disabling it would stop the screen doing it but it was taken out from kitkat. Does anyone know if any custom kernels would fix it? It's just really annoying.
What about setting:
/sys/devices/mdss_dsi_panel/cabc
to "0"?
One of the more pleasant surprises I got when I bought this phone was how dark the screen could get for night tile viewing. With Night Mode and the lowest brightness, I could browse my phone first thing in the morning without dying.
Now, on Nougat, Night Mode just adds a yellowish tint - probably reducing blue light or whatever - and brightness doesn't seem to go as low now. Kinda blinded this morning...
Is there some way of fixing this?
1.
2.
3.
And many more..
I probably should've specified I wasn't looking for a separate app for this purpose. I know that much!
Just wondering if I can get the built in function to be sensible again.

Surely.
No you can't.
Well,
Currently looking into downgrading to Marshmallow then. Newer doesn't always equal better, sigh~

Hi,
i want to disable Screen Brightness Machine Learning on my phone. It must be like Android 8.1
I mean the only thing Screen care for the Brightness must be Light Sensor. Because ML thing works like ***.
Is there any build.prop code or something like that? How can i do that?
Thanks.

You can either use the new Screen Brightness or turn if off completely.
Have you tried training it for a few days by adjusting the brightness to your needs?
For me, it works perfectly after the training phase.
There is no way a normal user can do it, on a locked device. I am sure there are ways with root there are ways to fix this. This was my biggest issue for a week when I got Android 9, and now 10 (since in 10 whatever was learned in pie, at least for me, was lost). After a week of teaching it how I want things to do, it just does it at it should.

The point is ML doesnt obey my commands. Thats why i want to disable it.
It learns ok. but when it finishes his learning phase i cant control the Brightness manually.
For example:
ML increases Brightness to %100
but thats too much for me for that moment
so i am trying change it to %50 and then
ML immediatly increases Brightness to %100
I cant control the Brightness after the Learning phase. Its just so dumb.
I just want back my old but gold Light Sensor.

What. Just adjust the slider dude... been using it since it was new and I can adjust the slider under the quick settings any time.
What do you mean by learning phase? It tells you, that leaning phase is over and it's not adjustable anymore or what? :laugh:

Indeed, you are right, the old fashion system pre-9 was much better, and much more reliable. You set a point on the slider and the auto-brightness only modified slightly in that area. Until the auto-brightness post-9 learns it's a chore, and after that... teaching it new things, it's again a chore.
The whole process is related to the Device Health Services subsystem where you can reset the whole learning to factory default. Maybe from there, you can have some success, but from what I've googled, there is no way to do that on stock locked. Maybe there are xposed, or magisk modules that could take care of that.

Wow.. I have never seen that. Been using 9 since it came out, with the latest sec. patch every time. I've adjusted the brightness many times, but I've never seen this happen.
Is it the same if you drag it instead of tapping a new location for the knob?
Also, I have the complete Digital Wellbeing bs disabled for a long time now, maybe that's why I've never seen this? Might have to do something with it.
