I searched and found no info on dimming the camera's LED. I want to be able to use as a flashlight, but I don't want it so darn bright.
Still looking at different apps on the Play Store, but I think it would have to be some kind of hack for rooted phones, which I haven't done yet.
Any one have any ideas?

I don't think it's possible. When you use it as a flashlight android apps have a setting called "torch" and that's it. There is no modification for adjusting brightness. Also, I looked in the /sys/class/leds/ directory for the camera led to be able to enter your own value for the brightness file, but nothing exists in there for the camera light. I personally like the bright led for a flashlight. If I don't want something super bright, I use a screen flashlight that just displays a white screen and boosts brightness to Max. I personally use a red screen though.

The tricky aspect of what you are talking about doing here is that the Linux kernel is your entire power management for the device. There might be a a root flashlight somewhere in the market that could accomplish this for you, otherwise it would take some adjusting at the kernel level... which again is your power control for hardware
Thank you guys for the help and info. It's not the end of the world if I can't do this, but now I know what to keep my eye out for.
The kernel is the key to over clock and under volt, so I understand that the kernel would have to support that.

Hey peeps!
Question First: Has anyone else found a LED flashlight app that works well on the DHD or Inspire that can dim the LED right down?
I want to use the LED on the back as a reading light so I don't have to drain the battery by using the screen but its simply too bright.
I am running an Inspire 4G on Revo HD 6.3.1. The stock flashlight app works well with the 3 levels avaliable and I don't want to kill the LEDs by over running them.
There are tonnes of flashlight apps out there, some using the led and some not. The ones I have researched either don't have a brightness adjustment on the LED or attempt to burn a hole in a sheet of paper.
The only app that I have found which relates to this is call "Reading Light" and is just an adjustable brightness grey screen.
If this has been discussed before please let me know and i'll request this thread be closed. I couldn't find anything regarding this aspect of the topic.
Regards,
Akida
I don't think this has come up before. Its a good request. I'd be interested in something like this.

Bump for confirmation of possibility please!
Btw .. how often am I allowed to bump? I couldn't find it in the forum rules.
CM 7.1 has a application called Torch which has two light levels. The dim one seems like it would be perfect for reading (it only uses 1 of the 2 flash LEDs). The bright level is insanely bright (much brighter than the Sense flashlight app).
There is an app on the market called Torch, but I don't think its the same one that comes with CM 7.1.

Hey that sounds like its worth a shot. Has anyone extracted the app from CM 7.1? I'm going to ask them for permission anyway.
Thanks for the info.
do you guys know how to or what apps can change the auto adjust level? and please dont say just manually change it, i like to use the auto feature, its there so i can be lazy.

You can go to settings> display> brightness and set it to auto brightness, or you can get the app "Quick Settings" it has a bunch of toggles

I think the OP wants something similar to what's in Cyanogen roms. I think he wants to adjust how bright or dim it gets on certain light conditions. I think I saw an app called Luminous or something. Now I'm drawing a blank.

Maybe if you found the file that holds the values, you could pull and push the file till you find what you like?
EDIT:
Try this, maybe this will work. I think this is what I saw once.
Lux Auto Brightness
https://market.android.com/details?id=com.vito.lux&hl=en
I think I might give it a try later on.
Juice defender has an option to set the brightness all the way from -80% to +150%. So autobrightness would have a larger (or smaller, if you prefer) range.

Have it. Recommend it. Slick app from a great responsive developer.
just use the notification bar
Hey guys
I found out that if you tap the notification bar on the top and slide your finger left or right, you can adjust brightness as you like. I think that is the easiest and quickest tip I found on this forum. not sure where I found it.. hope that helps..
^^ only works if the brightness toggle is off.. Awesome feature on sammys..

There is an app i am using that allows you to adjust the levels that the auto brightness use.
Called: LogGraph
it gives you a graph divided by roughly 12 steps of the brightness sensor so 0-12.
you can set the brightness level at each step the default (which i am using) is roughly:
Sensor% - Brightness level%
0-0
10-5
20-10
30-15
40-20
50-25
60-30
70-40
80-60
90-80
100-100

Thanks I was wondering why it didn't work.
Sent from my Hercules using XDA App
Reviving a slightly older thread here for some feedback.
Lux is a great and well designed app; I've been having issues with it - it doesn't seem to sample from the sensor (light or camera) when it wakes up, even though that is how I set it. I sent an e-mail to the developer, so hoping he can help me out. I also found it hard to understand the "levels" both in basic mode, and the lux/luma in advanced mode. I came from Cyanogenmod (on an Evo 4g) so I understand how the sensor works, but for some reason, whether it be the GS2 or Lux, the sensor does not seem to pick up a lot of variation in ambient light. I can cover up the sensor with my finger and the value that is getting doesn't seem to go below 2.
So I'm still struggling to get the auto-brightness (with an app or with the factory algorithm) to work properly compared to what I was able to get on my Evo 4g w/ Cyanogenmod (which was perfect by the way - once I have it all set up, absolutely perfect auto-brightness).
Actually I edited the framework-res.apk file and that did the trick. I tried lux before but it still didn't work like the default auto brightness.
I'm just sayin!

I'm guessing this is something that can't be edited live or on the fly? It's got to be signed and flashed?
If that works, cool, but I'm totally hoping for an edit I can make live to system files from Root Explorer for instance.

Yes, currently this is the only way to achieve this. Supercurio mentioned in one of his post earlier that he was working on an app that would allow us to make these type of adjustments.

I believe you that Lux doesn't work like the factory auto-adjust...no matter what an app. developer does, you can't replicate the responsiveness of what would be in the framework.
Could you explain further the edits you did and what it corrected? I am a software developer and I can figure out the basics, just was looking for an idea of what you edited in there and the specifics to get me going.
Thanks in advance!

I basically followed what they did here http://forum.xda-developers.com/showthread.php?t=1235212 to decompile the apk. I made adjustments to the value that represents the brightness under the lowest lighting conditions. I slightly increased the brightness under that value to help mask the blobs under low lit conditions. Hope this helps.

Yeah, saw that last night and just finished. Will probably need to dial in the values a bit to find what is optimal for me.
I'll post a Framework for others to use once I get mine all set. This is definitely the way to go for adjusting autobrightness.
Hello, I'm looking for a way to reduce the screen brightness even more than currently possible. It is too bright for me to read at night at the moment.
Is there some way?
Check the market. There are way too many apps out there to do the task you wanted.
via xda app
I already have but none of the applications on the market allow me to make the screen really dark. It's still pretty bright even after using programs like AdjBrightness or ScreenDim.
I'm curently using Screen Filter but that only puts a grey overlay over the Displayed Applications.
Try this one: https://market.android.com/details?id=mobi.pruss.superdim
I haven't tested it though.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
Already tried that, it is no darker than the lowest setting from the built in menu. Other Android devices can go much darker. I was hoping, that it is just a kernel issue or something like this.
How is it that sreec filter doesn't do exactly what you want? It gets very dark, doesn't it?
One other possibility would be to use Cyanogenmod or any other Rom that lets you set the light sensor levels manually. In my experience, this feature seems to save lots of energy. IF you manually set those levels to very dark, you may get what you are looking for ...
Hello Everyone,
I have a problem with my amami and I doubt I am the only one but for some reason people do hardly complain: the brightness even at lowest possible setting is still too bright.
I had this back when I had original FW and I am having the same issue with CM11 (latest nightlies). Using manual control or auto-brightness doesn't make much difference, i.e. in a totally dark room the ambient light sensor reports 0Lux and the screen is still too bright.
I found a workaround already (the ScreenFilter app that people recommend all over the internet) but it sucks because it heavily reduces the picture quality, i.e. visibly reduces contrast and especially the gray color resolution. And it also doesn't reduce power consumption like real brightness value change would do.
I looked around for possible solutions and there is a trick with writting a new value of current limit to Linux settings (some mA value between 0 and 20 to some max_current file in procfs). And this really helps but also impacts the maximum brightness, the screen is hardly ready in sun light with reduced current.
Is there a silver bullet? I am thinking about writing an app for that but it would require SU permissions and is kinda dirty to implement. Can anyone recommend a better solution?
have you tried the xposed Modul "minimum brightness" ?
Install Lux Brightness. from play store.
You can overboost it or make the screen so dark that you can't even see it.
Another great screen mod is Twilight which basically dims the screen red based on clock so it helps fall sleep faster when using phone before bed.

Yes, another vote for Lux. It lets you set brightness to negative levels, mine is usually around -50%. https://play.google.com/store/apps/details?id=com.vito.lux&hl=en

Thanks for the hint. I tried the Lite version and AFAICS it simply uses the same trick as ScreenFilter and other "sub-zero" regulators, putting an alpha overlay on top of the image stack.
You can identify this kludge easily by looking at the button areas, they don't get darker anymore. And you can see the black level not getting real black, i.e. the power consumption is not reduced.
However, Lux seems to be one of the better toys because of the plugin interface. Unfortunately there is no HW plugin for Sony devices but judging by the quick look at the Nexus-4 plugin (it's open source!!) it should be possible to adopt this method to Z1 as well. So, maybe when someone could eventually implement that.
xposed Modul "minimum brightness" works, i tested it for you. you can make the screen dim to complete black with your normal display brightness slider without grey or black overlay. it just sets down the minimum brightness level to 1 or 0 (default is 10 or 20), so it should also work with enabled auto brightness

As far as i remember, /proc is only used to call upon information, not to set specific values. What you are looking for is placed within /sys.
To be precise in /sys/devices/leds-qpnp-ee125e00/leds/wled:backlight/. There you will find a file called max_current with which you can easily control the brightness and set it to a very low level. Note that this actually dims the screen and not just applies a filter like most apps do...
One drawback is that the value will change again after you restarted the device. I set up a little flow with Automate β that takes care of this for me. I find this solution a lot better than all the screen filter apps.
This is true for CyanogenMod 11 and GreatDevs Kernel. It might be different on Stock. I know that the path for my Nexus 7 is sys/class/leds/lcd-backlight.
I hope this helps you a little bit.

I am wondering how you can claim that the result is complete black. Calling this black is like saying "TN monitors have good black values" (I know such people, they change their mind quickly when they see my Eizo with a VA panel at night).
No, seriously, the default was already 10 (see config.xml in cm11 repo) and the difference between 1 and 10 is hardly visible. It's still way too bright for work without eye strain in the darkness.
@Wooaarr: thanks, this is apparently the way to go, I just need to find time to configure it. And yes, of course, the file is in sysfs and not procfs (automated typing, when I grew up with Linux there was no sysfs out there ).

Hi guys
I was thinking if it is possible to use finger print scanner LED as a notification LED? I know it may not be currently possible but just floating the idea for the devs who make things possible all the time
I know the LED is huge to be used as notification LED but some people would love to have an LED instead of a ringtone or vibration alerts, thanks in advance for any help in this regard
I don't know if this is possible but this is a fantastic idea.
If this is actually possible it would be awesome!
Great idea, but is there really a separate LED ? I had always assumed that the FP uses the green lighting from the display itself....

Yes I thought it was like that.
I think it doesn't matter if there's a separate LED to light up the display or part of the screen itself is used as a notification LED, but I think all possibilities are there, to choose the color, random colors each time or per app, position on the screen etc...
I don't really see the point in using those specific pixels as a notification LED when any other pixels on the display work just as well. And if anything, you'd want to avoid lighting up the fingerprint pixels too much since they are being used more at high brightness and therefore more susceptible to burn-in.

Amy work on this?
I disabled fps on my 6t because of the annoyingly high brightness of this green circle when your finger is close!
I don't think there is a led, I saw a video where they open the 6t and access the sensor module, it's just a camera sensor under the screen, the amoled brightness is boosted in this particular part of the screen, that's all.
Thanks God they didn't use a laser light, half the people would go (really) blind.
You can use an app like noled to simulate a led anywhere on your screen.
