Hi! I'm a first time poster here, have had my TP for a week now (previously used SE UIQ phones). Anyways, first I just wanted to THANK all of YOU who make these amazing apps and tweaks for this very cool phone!
Now to the point. I like the idea that the light sensor adjusts the backlight level automatically, but I find it much too bright especially in very dark conditions. Even if it's completely dark, the backlight doesn't go all the way down, i.e. I can make it much dimmer by manually setting the brightness to a low level.
Is there any way to "calibrate" the brightness for the auto adjusted backlight (so that if it's dark it would lower the brightness even more than it does now, and if it's bright it would set the backlight to 100%)?
Thanks!
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).
Hello Friends of the Forum. I've been researching something for many years, and I've never found a real solution. The next, virtually every smartphone enters the maximum brightness mode when Light sensor exposed directly to the sun, but this does not happen if you are in a shadow, such as a sun umbrella or a tree. Many people make confusion because this maximum brightness does not depend on being selected the auto brightness, is only disabled on developer option. I dream of getting access to this maximum brightness without the need of the sun, because it would be very useful on cloudy days with a lot of clarity, or in moments of shade on the beach, to make video calls on the street during the day. If you want to take a picture of the sunset, for example, the brightness is also not activated, as the sun will not be reflecting directly on the sensor, but on the back of the device. My intention is not to use the maximum brightness all the time, but to recalibrate the brightness sensor, so that it activates the "boost" without needing the direct sun in the face of the device, but in any bright environment. I just want to walk in the street during the day with the screen really shining in my face! Does anyone have that same interest of mine? Thanks! (I'm using a translator, I don't speak English well, sorry for anything).
