[REQ] CM7 auto brightness customization

CM7 is a great ROM but for me, Sense roms have more advantages on the evo. One of the advantages of CM7 is the ability to completely customize the auto brightness function. When I ran CM7 nightlies I spent about an hour dimming the lights to program it perfectly. When you're in a dark room you don't want to pull your phone out of your pocket and blind everyone around you. When you're out in the sun, you want to be able to actually see the screen. Unfortunately, it seems like the sense auto brightness does a horrible job of getting the phone really dim in the dark and doesn't react quick enough in the sun. There are so many widgets out there for people to quickly adjust their screen brightness because the auto isn't good enough. This is ridiculous! The evo 4G is capable of having the perfect auto-brightness. We shouldn't have to be stumbling to click on a widget to self adjust the brightness.
I've searched all over the interwebs and nothing like this exists for non-CM7 Android devices. Someone please either port the CM7 auto brightness customization settings or create an app!!! Something similar to the old school Lumens app from Windows Mobile. You would be a hero to many.
Also, I would love to do this but I have zero programming skills.

I created an app that does this exactly (it's in beta at the moment):

How well it performs depends on how good the light sensor on your device is. The app does have data filtering to try and get better readings from bad sensors, though.

Just installed CM7.1.0 and haven't yet found all the settings but stumbled upon some good ones already. A brightness one would be great because I would LOVE for my phone to go brighter in direct sunlight and dimmer in controlled areas and in the dark. I want to tweak mine as you described. Is this in the Cyanogenmod settings within the Menu->Settings menu or is it somewhere else?

Yeah, and look for auto, and 'other' there is awesome control in there. You can even control how bright your capacitive buttons light up, and what level of light they respond to.
Really nice feature.
To the poster who is working on this, I'll def be having a look. Thanks.

Screen dimming app.

If any of you other users out there feel that the whites on this thing are too awesome for super late at night like I do, I found a app when searching for a f.lux type alternative for android. I have been using this app to help ease the stress on my eye late at night. I dont know about the techical side of what it does, or any of the jargon involved, but it applies a filter of sorts to dim the screen further than what the phone allows. I been using it a lot lately and figure I would share with you guys. If anyone has any recommendations for other similar apps, please share.

Or just turn on "Background Color" in Power Saving Settings.

Or if you want the screen brightness itself to be lower than what most ROMs allow, you can use this app called RootDim. It worked amazing on my xoom, not sure if it works on the SGSIII yet..
It requires root though..

Screen filter does the same and doesn't require root. On our AMOLED screens this can save battery.
Also you can turn off those damn capacitive key lights by going to Settings>display>"touch Key light duration"> Always off.

I can confirm that Root dim does work for the SGS3 I use it on my phone.

Lux is an amazing auto brightness app and setting it up for your tastes is incredibly simple.
Go out in the sun and turn brightness up all the way using the app then "link" that setting, go in complete darkness and set it to your taste and link it, then indoor lighting, set it, link it. It then uses just those 3 settings to create a smooth graph of brightness values that are all perfect. You can have as many links as you want but i find the less settings you put in that app the better.
I tried all the suggested ones in here btw.

I've tried and really like Lux (in fact I'm considering purchasing it soon) but I've noticed two issues. First is that sometimes it will not refresh itself and I have to open up the lux dash to get the brightness to change. It doesn't happen often, but it happens often enough to be annoying, and I have it set to automatically.
Also, (and this may simply be an issue with the S3 and not lux itself) but sometimes I will be in a decently lit room and be at 1 lux, while lights out is 0. Not a lot of variance unless it's really bright outside. Have you found anyway to increase the light sensors sensitivity?

Try setting it to be always active in the task bar, that prevents it from being killed. Also try setting it to not use raw values for light sensor readings, this gives you a simple scale of 0-10 for readings and total darkness always reads as 0.
Edit: oops reread your post. That's weird that it is reading indoor light at 1. I usually get around 2 or 3. I used to have a screen protector on that covered the light sensor and that put it all over the place. Maybe that is what's causing it?

I noticed the same behavior with the free version. In my case, the lowest value the HTC Desire S can reach with its default Android auto brightness is in fact about 15%.
In LUX settings you can configure the "0" value to be lower and "bypass" the freeware limitation (you can't configure sub-zero levels in the free version). This will work when you test it in the dashboard, but during regular use the light level never goes below the 15% limit already set by the OS.
What I did was purchase the full version (to get astronomer mode along with all the settings unlocked) so I was able to leave the 0 level at its default 15% but link some light intensity values to sub-zero percentages. Guess what? It works great! Once you go into a very dark room, the display dims as far as you set it to.
Another problem with the free version was that a few times I unlocked the phone outside in full sunlight and LUX did not increase the brightness. It appeared almost completely black because the light level was at about 15-25% (the same level it would be inside a low lit room).
Again, with the full version I did not notice this problem (I've used the free version for 1 day and the paid version for 1 day but running tests in different light levels inside and outside).
It's like the free version is a bit buggy on purpose, and I remember uninstalling LUX free about 2 months because of this; I was thinking that if the free version does not work OK, I shouldn't buy the full version. Apparently this is not the case (touch wood).
Just for the record, it's on "dynamically adjust".

If the display is a bit dirty (oily, dusty, etc) around the light sensor, you can try to clean it. If this is not the case, open the dashboard, let it determine the light level or hit "auto" a few times and make sure the reading is correct. Then just slide your finger along the yellow line to find the appropriate brightness level and long press the chain to link. Go to a brighter lit room then go back to the first room and see how LUX behaves. Also lock/unlock the phone a few times and see how it goes.
If you still have problems running LUX, disable it and check the default Android auto brightness to make sure it's not a sensor issue.
LUX also has the possibility to set the response delay under Settings -> Advanced -> Developer Settings (the last to just on the bottom, but for this you would need to buy the full version.

Thanks, but I think it is more of an issue of the sensor not being sensitive enough. I'm not sure if this is anything you can change in lux or if it would have to be edited in the kernel (or if it is fault of the hardware) but I just feel like the sensor doesn't go down low enough. As I said, I can get down to 1 or 0 in a decently lit room, and yes I have tried cleaning the screen. It's not like it jumps around or anything so it's not like I would notice anything in default auto brightness, it's just that it doesn't seem to be sensitive enough.

Screen filter is great!! I use as well!!!

Well for my Desire S, the lowest light level that the sensor can read is 160 lux (raw value). You can try and set LUX to use raw values because this is more accurate in my oppinion.

Another +1 for Screen filter here

Does anyone know how to use "luma" values for automatic adjustment in Lux instead of "lux" values?

What I have noticed on my phone is that "luma" readings are taken from the front facing camera, while "lux" readings are taken from the ambient light sensor (you can chose which one to use in the settings).
I suppose the front facing camera uses more battery than the light sensor; it also appears to be more sensitive because it can read more light levels.

I guess so. Thanks! But doesn't that kinda defeat the whole purpose of Lux? Because you can't use automatic mode with the camera(s).... so then what's it good for?

Well even if you don't have an ambient light sensor, you can still use the camera to check the light level when you unlock the phone and let LUX adjust the brightness level. Of course it's not dynamic but it's still better than having the brightness at 50% the whole time or changing brightness levels through a widget..

auto-brightness is terrible [SOLVED]

Way too bright. Never remembers my preferences. Every time I turn in the screen, even in a dark room, brightness us 50%. I'm constantly turning it down but it goes back up.
How can I fix this? I refuse to believe my only option is a third party brightness app.
-EDIT- Here's the solve:
Just go to apps>settings>applications>application manager>more>reset apps preferences. This clears out any personalized brightness settings. This worked immediately.

Well turn auto brightness off.

No. I want auto brightness to adjust to the ambient light. That's the point of auto brightness. 50% brightness in a movie theatre means something isn't working right. And the S7 auto brightness is supposed to be personalized to the user but obviously this isn't working either.

Mine is working just fine in any ambient, I don't know what settings you mess up with.

alright, smart alecs. Just talked to Samsung Support. Just simply go to apps>settings>applications>application manager>more>reset apps preferences. This seemed to fix it. The tech said sometimes carrier updates can corrupt settings. So that's neat...

Every time you install an app on your phone they change something. Some times are nothing important, other times they mess with the whole system settings.
Glad your settings are working now.

Actually i had the same problem when i got the phone, did a bit of search n found it has a smart brightness feature.
You have to choose ur brightness level according to the ambient light in the room cuz it remembers each time you set the brightness level according how much light the sensor is picking.
Short answer, keep changing the level of brightness for couple days until it learns the new levels.

When I'm outdoor in extreme sunlight the phone's brightness goes all the way up and then it enters a mode where colours seems washed out. But only if the light is very strong. Does your S7 behave the same?

I may have to give that app settings reset a try. At first the auto function seemed fine. As time passed it grew worse. However, mine would be too dark in dimly lit situations and semi-acceptable in bright conditions. I finally turned off automatic as it was extremely annoying and almost always incorrect.

Yes. That's a special boost mode I think. Without it the screen wouldn't get bright enough to see well.

Adaptive brightness gone crazy after upgrading to oreo?

Not sure its only me or the Adaptive brightness option is way too "sensitive" after upgrading to oreo... Its like brightness gets "moving" every tick my phone moves Could it be a bug? Or configurable somewhere in services settings? Pretty annoying

anyone got such screen brightness problem on mix2s?

I just received my mix2s last weekend, and I have been using it for several days.
But through these days, I find it that when you turned off the automatic brightness, and the phone is displaying some dark or black contents, the brightness will get lower by itself, but when you turn to some colorful or brighter contents, the btightness will get back to normal itself.
so I'm wondering is there anyone got the same problem like me? and how can I turn it off? I mean, just don't turn down the brightness itself when showing dark contents.

Just checked it on my phone and you are right, screen becomes darker when you display dark content. Also with auto brightness disabled. Maybe it has something to do with the automatic contrast settings
Edit: I was right, if you disable automatic contrast the brightness stays like you set it

can you tell me where is the "automatic contrast" settings? seems that miui just deleted it

It seems to be a problem since the last mix 2. you can try search on google and on this forum.
There are few fixes you can do, just go over the search. I didn't do it myself because I just manually adjust the brightness myself. It is pretty annoying though.

Thank you I could not figure out what was causing this on my phone. When watching Youtube on lowest brightness at night the screen would fluctuate and it drives me crazy. Did not know that had something to do with it but now I know.

This is an old thread, but it's high on Google rankings, so I'm adding to it.
I think my main annoyance with this is the position of the sensor. If I'm typing or scrolling with my thumb, it seems I'm covering the sensor with my hand, so it thinks it's gone dark, so decreases brightness.
Disabling the auto brightness fixed it for me
