[Q] How to change auto brightness settings? - Galaxy S II Q&A, Help & Troubleshooting

Hi guys!
I don't like my auto brightness settings on my kernel so i would like to change it because it drains battery like hell
I am using ICS 4.0.4 and Siyah kernel 4.1.5. Where are the settings located and how do any changes effect the brightness? Please explain any step made and all the modification made for better battery saving!

This might be a good place to start (I found this via a Google search, BTW).
Edit - And because I'm such a good bloke, here's the post on XDA that post links to.

Ok. Nice. But can i add more items to the code? For example:
<integer-array name="config_autoBrightnessLcdBacklightValues">
<item>5</item>
<item>50</item>
<item>100</item>
<item>150</item>
<item>200</item>
<item>255</item>
</integer-array>
There are 6 items instead of 5.

Setting these in your build.prop would actually be decreasing the quality - if they are even used, which I don't believe they are any more. The STOCK bit rate for the Note actually goes up to 20,000,000; far more than the 8,000,000 listed here. And these aren't defined in the build.prop, but the media_profiles.xml (if I remember correctly, it's in /system/etc/) which is used because there's multiple quality profiles; not just one bitrate or quality setting. Stock, the Note can do up 1920x1080p at 30 fps (variable), with stereo audio being recorded at 48KHz at a bitrate of 156,000 (constant). I've verified this by looking at the files I've recorded with MediaInfo on my PC.
As for the JPEG decoding memcap, that is also already set to 20,000,000, once again far greater than the 8,000,000 listed here. I have actually modified my XML file to allow for up to 130% quality which does seem to make a difference, using these settings:
Code:
<ImageEncoding quality="130" />
<ImageEncoding quality="100" />
<ImageEncoding quality="95" />
<ImageDecoding memCap="25000000" />
Earlier in the file I also adjusted this to account for the increased quality (I don't know if this is necessary or not, but it hasn't broken anything):
Code:
<!ATTLIST ImageEncoding quality (130|100|95|90|80|70) #REQUIRED>

Yes, for sure.
i'm using cm10 on my sk17. and in there is a line in the file "echo 500 > $dev/button-backlight/max_current" by default. and the brightness is very high. Tried various times and found that the minimum value that can be given is 150 on cm10. If you want more light, just increase in small steps...

ok thanks.
why this is not f**king working for me ...?!?
ok, had this problem and dont know wheres here the problem
1. i hate bbl (=buttonbacklight) so i disable it with Mini-Ultrabrightness mod and all was fine!
but after changing kernel to kappa kernel (1.6) the bbl was very bright AND NO way to disable it...?!?
---> edited hw_config file like here = no changes
---> flashed Mini-Ultrabrightness second time = no changes
---> make a script with value echo 1 > $dev/button-backlight/max_current / and also tested values for 1 button etc.. = no changes
before it was no problem changing the bbl, but after usig kappa kernel the bright backlight persist, even after flash diffrent kernels
..... MY QUESTION IS: anbody knows whats happenning there?? or haw to diable bbl with a diffrent (safe ) method??
it would be really nice.
thanks. and SFBE (=sorry for bad english)

Strange because kappa 1.6 is the only custom kernel with which I have tested all these mod and they all work fine with this kernel[kappa 1.6 for simultron].

Under LMU AS3676 Configuration add these lines-
echo 1 > $dev/button-backlight/max_current
echo 0 > $dev/button-backlight/max_brightness
echo 1 > $dev/button-backlight-rgb1/max_current
echo 1 > $dev/button-backlight-rgb2/max_current
Now reboot 2-3 times and between every reboot provide some time also delete any previous lines which are similar to these or simply replace there value with these one.
Interesting thread...
Is there any way guys for the capacitive buttons to have backlight ONLY when we press them, not only every time the screen is on?
Alternative: can we change their backlight timeout?
thx

On setting :
Use 2G only
Disable airplane mode
Change brightness to little dark
Dont use task killer (battery willl drain fast with this )
Add this on build prop line (dnt forget make a backup) :
ro.ril.disable.power.collapse=1
pm.sleep_mode=1
proximity_incall=enable
usb_wakeup=enable
power_supply.wakeup=enable
ro.config.htc.nocheckin=1
with above step you will got ultra battery friendly

replacing framework-res.apk without nuking my phone :)

Im working on modding the auto brightness values in framework-res.apk because i find the stock values to be too dim in a medium lit room and too bright in a dark room.
i find alot of tutorials but they are older so im trying to check in to see if this is still valid.
i used this guide http://forum.xda-developers.com/showthread.php?t=1806602 to decompile and then edited res/values/arrays.xml and then recompiled.
then i used 7zip to copy the META-INF folder and AndroidManifest.xml from the original framework-res.apk to the new one.
so now i want to swap them out and avoid bootloops and stuff.
so i see this guide. http://www.androidtablets.net/threads/how-to-manually-replace-framework-res-apk-on-stock-roms.43716/
should this work?
im not sure how to create a flashable zip... again i see alot of tutorials but they are older so im not sure they are valid and wont bork my phone.
thx
Brian
Ok I manned up and tried it especially since I had a nandroid bavkuo. it looks like it worked ok. It started crashing out after I replaced the file but after a reboot its working so far.
We'll see how it works in varying light conditions.
Brian
i didnt nuke my phone but the lowest brightness is still at 50.... which is too high.
back to the drawing board.... ie dig through the guys flashable zip that did it already here... http://forum.xda-developers.com/lg-g3/development/mod-lower-autobrightness-values-t3054000
Brian
this is more my ramblings and thinking outloud than a question.... but i think i may have found it.
i only edited arrays.xml to this:
Code:
<integer-array name="config_autoBrightnessLcdBacklightValues">
<item>10</item>
<item>40</item>
<item>90</item>
<item>130</item>
<item>160</item>
<item>190</item>
<item>205</item>
<item>220</item>
<item>235</item>
<item>245</item>
<item>255</item>
</integer-array>
but i didnt change integers.xml
Code:
<integer name="config_screenBrightnessSettingMinimum">50</integer>
or this
Code:
integer name="config_screenBrightnessDim">50</integer>
so when logging a logcat and covering the sensor, i could see the brightness only get down to 50 after i paused it and scrolled through the log.
now i changed those values both to 10 and im going to test again.
Brian
ok i changed the values in arrays.xml as set above and in integers.xml set the above values to 10 and then followed the guides earlier in the thread and it worked.
while running catlog, i can see the display brightness be commanded down to 10 when i cover the sensors on the top of the phone.
i have the middle ambient light levels pumped up a bit and the low light alot less than stock and it seems to be just about where i can leave it on auto all the time and have good brightness.
if someone wants to move this thread to another section if it is applicable, go ahead.

How to set screen brightness in watch using adb command

Hello guys,
I was upset with screen brightness on my Amazfit watch and with a little research figured out how to set screen brightness with adb command. So here it is:
If You want to know what level of screen brightness is just type this:
adb shell settings get system screen_brightness
It will show You a number (default is 60).
To set screen brightness type:
adb shell settings put system screen_brightness XX (where XX is number between 0 and 255)
P.S. backlight settings on my watch is set to "Always on"
Hope it will help to someone.
You can also modify the framework-res.apk
<integer name="config_screenBrightnessSettingMinimum">0</integer>
<integer name="config_screenBrightnessSettingMaximum">255</integer>
<integer name="config_screenBrightnessSettingDefault">10</integer>

and
<integer-array name="config_autoBrightnessLevels">
<item>20</item>
<item>50</item>
<item>300</item>
<item>400</item>
</integer-array>
<integer-array name="config_autoBrightnessLcdBacklightValues">

You won't ever need that in outdoor conditions. It is a transflective display.
Under bright illumination (e.g. when exposed to daylight) the display acts mainly as a reflective display with the contrast being constant with illuminance.
Only in dim and dark ambient situations is an auxiliary transmissive backlight needed. Then your only option is to amp up the backlight, as discussed here
Read More
Update the ROM to 1.3.4f(latest as on date).
It has the option to adjust the brightness.
Your wish has been granted. @tibinet
What is framework???
