If I want to lets say never want the brightness to go below 10% with automatic brightness how do I do this? I want it to play within 10-100% brightness and never let it go to 0%. I am surprised no android phone has such a useful feature built in where we could manually set upper and lower parameters for auto brightness.
I am running stock rooted rom.
Can't with stock ROM as far as i'm aware, however many ROMs have exactly this feature and you can fine tune it as delicate and precisely as you like. I believe most of them have the settings in the Display area in the settings. Excellent feature that should definitely be a part of the stock ROM (simple presets and advanced tuning would be quite awesome for stock).

I can see more people breaking stuff there rather than fixing it. The autobrightness works decently on 4.0.4, only wish it was smoother by default.
My only problem with auto brightness is when it starts up it can take seconds to brighten up. I dont understand why it must start from 0% every single time I am indoors. I think it should wake up on the last setting and then lower it if needed, that would have been much better.
On GB it used to stay at 0% even in a rather well lit room but on ICS it goes to 10% in my room. It's just that the whole waking up at 0% is still really annoying.
Man custom rom I am not sure I am interested in them yet. Is there no app that can do it?

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.

Hello everyone.
Shorter version:
CM7
Pros:
1. Amazing battery life.
2. More options and settings (after all it is cm).
3. Nicer user interface.
4. Flash player 11 for arm6 is working perfectly.
5. No bloatware.
6. Fast enough and stable (not one fc so far).
Cons:
1. Front cam. Although back one is working fine it would be nice to have a front one as well. Minor issue though, I don't use it anyway.
2. Fm Radio is always turning my bluetooth on when I start it and use it. Don't know if it is supposed to do that but it is a real battery drain and I don't want to use 3rd party apps if that is even possible. This is a minor issue since I don't use it often.
3. Led notification turns green at 90% and more when charging and my phone tricked me to unplug quite a few times Also a minor issue.
4. Default automatic brightness is just terrible. I know that they can be modified through cm settings>display>automatic backlight but I am not sure what values to enter to get the best and optimum results. I just cannot get them quite right.
So, to conclude. Cm7 is just great and really ready for daily use. I only need to set up the automatic backlight properly and this is where I need your help. If anyone knows the best values for these settings, please, write them down in this or the original cm7 thread.
Best wishes
I've set the status bar notification for backlight to 25/50/75/100. I feel that these values suit every possible condition.

Hi Alex, you must have misunderstood me. I'm not talking about those settings. I don't want to adjust brightness manually. I'm talking about window length, reset threshold, sample interval and custom light sensor levels so my phone can automatically adjust brightness. These can be found in cyanogen settings>display>automatic backlight
Regards
Ah, ok then.. Unfortunately I did not have the patience required to set/tweak them.
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..
Not sure if this is a Nexus5 or Android issue ...
Not sure if this is because I'm moving from an AMOLED to a IPS LCD ...
but I find the Auto-Brightness less of a function and more of a roller coaster ride.
- At home, in a well lit environment, the phone defaults to max brightness, which doesn't seem correct.
- In a dark room, upon wake of the phone, it correctly selects a lower brightness, yet will randomly ping up to max brightness, then settle back down.
The screen on the Nexus5 is absolutely gorgeous, but it just can't seem to select and lock onto the proper brightness level with respect to ambient light.
Is anyone else experiencing auto-brightness wonky-ness? Are there any potential fixes?
Everyone AFAIK suffers from it on nexus 5.
I have a horrible feeling it's a hardware fault, as none of the other Google devices on kitkat have this issue.
yeah the auto brightness seems to be too aggressive, but i'm sure custom roms will have the ability to tweak the auto brightness settings. i think even gravity box has some tweaks for the brightness
If you download Android Sensor Box, you can check the Light sensors. I think it may be bugged with Halogen lighting (correct me if I'm wrong). My home is ~ 18 years old, and we have some bulbs that have not been changed yet (yellow). Sometimes when I use my N5 under those lighting, the sensors go whack and don't register properly picking up 0lx, then spike up to 30000lx. Once I move to areas in the house with newer bulbs, the sensors work normal, picking up the right readings. I'm not sure if it's a rom issue or hardware issue, but my cousin also has a N5 and his worked fine. I tried flashing a new rom and mine still acted up fresh after boot (1st app installed after fresh flash was Android Sensor Box to test).
As a rule I don't use auto brightness. Just get something like lux or install exposed and enable a mod to let you adjust it by sliding your finger across the notification n shade. Easier and faster.

I find that autobrightness will auto-turn on, even when i don't want it to.
There is something funky about it, I can either make the phone too dark (using lux) or too bright (using default settings)
I'm still not happy.
Tried Lux, tried adjusting the brightness tables via Gravity Box, used Twilight (to dim at night), no matter what, N5 just wants to be at full brightness all the time!
I had my Nexus 5 in the cinema the other day. The phone was sat in the cup holder by the chair for the most part of an hour when I quickly replied to a text. On turning the screen on it was on full brightness and what's worst is it took around 10 seconds for it to go down. There is definitely something not quite right with it.

Hi, I have been experiencing this as well, so I attempted to fix this at ROM level. The solution requires Xposed framework, so it works only on rooted devices (related discussion).
Has anyone else had issues with their Adaptive Brightness not working. Toggling the setting has no effect on my display. For such an expensive phone I expect things like this to work.
Yes, it doesn't work that great for me either. I mean I can see it adjusts the brightness "somewhat". But it appears it is not nearly as dramatic as on my Galaxy S7 which would pretty much perfectly adjust the brightness.
I agree that a phone this expensive should do it correctly out of the box. Google please listen.
This is the intended function as I understood it, so I googled it and here confirms. This is not intended to operate the same as auto brightness many other phones use.
In Android L, Google's introduced a new feature called Adaptive Brightness that combines manual and auto brightness. You can manually adjust the brightness level to a state you like. Once it's set, your screen will adjust based on ambient light so it stays at the same brightness relative to the light around you. This way you can set the screen to your preferences without sticking to an absolute level.

Been this way a long time. Would this be your first Nexus/Pixel phone?

The problem I have is that every time the phone is rebooted, adaptive brightness is set back to Off, even though it was On when the phone was restarted. Running NDE63V and not rooted.
