Turn Off Backlight Button Android Oreo - Android Q&A, Help & Troubleshooting

how tu turn off backlight button hw on android oreo?
i already use this step
changing /sys/class/leds/button-backlight/brightness" file from 40 to 0 and
echo "0" > /sys/class/leds/button-backlight/brightness using terminal emutor
both step are success but its like temporary. just few minute then button light is lighting up.
thank you

set the permission to r-r-r- and then it would be ok

[SK17i] + CM7 Bright LED (back + menu buttons), solution

Since I can't post in the Development-thread due to my post count being to low I'll write here. Cred goes to eidos on swedroid.se
By altering hw_config.sh you can make the strong LED-light on the back and menu button
[system root]/etc/hw_config.sh (check permissions before and after modifying making sure that they are the same)
Make a backup of this file before editing.
Replace the following rows in using Root Explorer (activate Read/Write-mode) and text editor (by longpressing "hw_config.sh" and choose "Open With" and then "Text Editor")
echo 2000 > $dev/button-backlight-rgb1/max_current
echo 2000 > $dev/button-backlight-rgb2/max_current
with this single row
echo 2000 > $dev/button-backlight/max_current
then press menu and "Save & Exit" and reboot your phone (after checking the permissions again).
If this doesn't change the brightness you probably didn't have the right permissions after saving the file.

[Q] Xperia Active - factory stock ROM with Flashtool / little project :)

Hi guys,
ok, I'm a noob in android development / modding / rooting. And yes, my English is not the best, sorry I'm from Germany. I can’t post at the “development” – forums, because I don’t have enough posts yet. Before I’m going to spam, I decided to post in the general forum 
So what am I going to do?
I got my Xperia Active (ST17) last week. There are 2 issues that disturbing me.
First the light sensor.
Second the soft key backlight.
So I decided to root my phone and customize these two issues.
One thing I worry about is, how to get back to factory state, if something goes wrong?
I read about the tool “Flashtool”. But for this I need a stock Firmware Rom from Sony Ericsson.
So my question is, is there a stock ROM for my Xperia Active (german language)? And where can I find and download it?
When I'm secured to flash back to factory state, we can talk about how to solve the light sensor and soft key problems.
I would be happy about your support for a noob like me
Best regards
Edit:
My current Firmware Build is "4.0.2.A.0.42". Is there a download source to download this firmware for my xperia active?
For modifying lights you can use "superDim"

Superdim doesn't work the way it should...
I extracted my hw_config.sh:

#Sensor on/off. 1 = on, reg 90h
echo 1 > $dev/lcd-backlight/als/enable

echo 6450 > $dev/red/max_current
echo 7950 > $dev/green/max_current
echo 4500 > $dev/blue/max_current
# ALS curve display BL [grp],[Y0],[Y3],[K1],[K2],[X1],[X2]
echo 1,30,255,54,52,1,65 > $dev/lcd-backlight/als/curve
# ALS curve key LED 2 [grp],[Y0],[Y3],[K1],[K2],[X1],[X2]
echo 2,48,0,128,128,4,10 > $dev/button-backlight/als/curve
# ALS curve RGB(red) [grp],[Y0],[Y3],[K1],[K2],[X1],[X2]
echo 3,71,255,64,32,5,37 > $dev/red/als/curve
# ALS curve RGB(green) [grp],[Y0],[Y3],[K1],[K2],[X1],[X2]
echo 3,71,255,64,32,5,37 > $dev/green/als/curve
# ALS curve RGB(blue) [grp],[Y0],[Y3],[K1],[K2],[X1],[X2]
echo 3,71,255,64,32,5,37 > $dev/blue/als/curve
This part should do the ambient light sensor and button backlight part.
So my question:
How to modify this config to disable light sensor (and set brightness to 100% fix) and button backlight completely?
Thanks a lot

my setting that im using with my active.. disabled light sensor as well...
echo 0001 > $dev/button-backlight/max_current -set echo 1000 to 8000 for you to dim it... 0001 to turn it off...

Neo V has two button backlight, so if you own a Neo V, or if you are using a rom like pureness (which developer has neo V)...you will find these settings rgb1 and rgb2.
I have a Neo, but I use pureness so I must edit both.
So, go to
Go To /sys/class/leds/button-backlight-rgb1 and change brightness to 0 and max_current to "1". Do the same in the folder "button-backlight-rgb2.
Then Go To /system/etc/hw_config.sh and scroll down all the text. In the last block you have (not directly in order):
echo 1 > $dev/button-backlight-rgb1/als/enable #Sensor on/off. 1 = on, reg 90h
echo 1 > $dev/button-backlight-rgb2/als/enable #Sensor on/off. 1 = on, reg 90h
change to
echo 0 > $dev/button-backlight-rgb1/als/enable #Sensor on/off. 1 = on, reg 90h
echo 0 > $dev/button-backlight-rgb2/als/enable #Sensor on/off. 1 = on, reg 90h
then under some lines get
echo 900 > $dev/button-backlight-rgb1/max_current #Max current in uA
echo 900 > $dev/button-backlight-rgb2/max_current #Max current in uA
change to
echo 1 > $dev/button-backlight-rgb1/max_current #Max current in uA
echo 1 > $dev/button-backlight-rgb2/max_current #Max current in uA

I'm using init.d script instead of editing the hw_config. When u want to enable it later on, just delete the script. Works on my I-Scream 587. Also works on my friend's arc s, but need to edit it a bit.
But the concept is mostly the same.

I think the backlight is quite useful too to disable it.
However may I know if there is any way to disable Home key during sleep mode? To wake the phone, simply just press the Power key at the side.
I hate to see my phone always accidentally turned on when I put it in my pocket (somehow because of wearing tight jeans, Home key can be accidentally pressed).
Thanks

Problem Button Backligh witch codename 9.3 no light

hi guys, sorry for my English.
I have installed the codename 9.3 and since I have not installed this light in the buttons (the two middle stripes)
probe to this thread
http://forum.xda-developers.com/showthread.php?t=1695362
and modifying thousand times hw_configh.sh and this tutorial
Below procedure actually work for me on my XPERIA Neo V (MT11i) with codename 9 ROM
XPERIA Neo V has two backlight behind home buttons one coded as rgb1 and other as rgb2 I'm going to disable both
1. This step will persist the values after reboot and completely disable the LED backlights
Go to folder /etc
Open file hw_config.sh
2. Go to line "echo 1 > $dev/button-backlight-rgb-1/als/enable"
Change echo to 0 like "echo 0 > $dev/button-backlight-rgb-1/als/enable"
3. Go to line "echo 1 > $dev/button-backlight-rgb-2/als/enable"
Change echo to 0 like "echo 0 > $dev/button-backlight-rgb-2/als/enable"
4. Now Go to line "echo 900 > $dev/button-backlight-rgb1/maxcurrent"
Change echo to 1 like "echo 1 > $dev/button-backlight-rgb-1/maxcurrent"
5. Now Go to line "echo 900 > $dev/button-backlight-rgb2/maxcurrent"
Change echo to 1 like "echo 1 > $dev/button-backlight-rgb-2/maxcurrent"
in folders button-backlight-rgb1 and 2
modify the brightness to 255 and reset back to 0 not to do
Just delete "20disable-button-backlight" in init.d folder & reboot. No need to edit hw_config.sh, quite easy.
Also, this thread please. No need to open new thread with the same topic.
works! but when lock screen no longer works. Back to work temporarily to adjust the screen brightness, I think it has something to do with the automatic brightness

[Q] Proximity sensor sensitivity

As i keep ending calls unwillingly:
Is there a way to change the sensitivity for the proximity sensor?
Anybody have the same problem?
Using the test in "Xperia Diagnostics" the proximity sensor on my Xperia U on latest FXP is turning on/off at about 15mm, which is a bit too little. When i do the test holding the phone to my ear, there is no constant vibration but turning on and off, which happens during calls too, i guess...
Thanks for any input..
PS:
my ears are quite normal, if some are wondering

Anybody knows, where the settings for the sensor are stored? in the Phone-Application, in the Rom, in the Kernel, .... ?
Is there an app that lets you set the distance for the sensor for our device?

Can somebody confirm this?
Hello guys in my attemp to fix this really annoying bug (all the time calls were hanging or buttons were pressed) i decided to get my hands dirty and take a look!
So the calibration for the proximity sensor is done in the /system/etc/hw_config.sh
Requirements
ROOT
Root Explorer (or a filemanager of your choice with enables acces to system and edit files as text)
So changed the following lines of the originial hw_config.sh of firmware 6.1.1.B.0.54 ( i think that at every fw is the same configuration please provide feedback)
Code:
# Proximity sensor configuration
dev=/sys/bus/i2c/devices/2-0054/
val_cycle=2
val_nburst=0
val_freq=2
val_threshold=5
val_filter=0
echo $val_cycle > $dev/cycle # Duration Cycle. Valid range is 0 - 3.
echo $val_nburst > $dev/nburst # Numb er of pulses in burst. Valid range is 0 - 15.
echo $val_freq > $dev/freq # Burst frequency. Valid range is 0 - 3.
if `ls /data/etc/threshold > /dev/null`; then
cat /data/etc/threshold > $dev/threshold # Use value from calibration
rm /data/etc/threshold # Remove temp file
else # No value from calibration, use default value
echo $val_threshold > $dev/threshold # sensor threshold. Valid range is 0 - 15 (0.12V - 0.87V)
fi
if `ls /data/etc/filter > /dev/null`; then
cat /data/etc/filter > $dev/filter # Use value from calibration
rm /data/etc/filter # Remove temp file
else # No value from calibration, use default value

As for now i think the overall experience of calling is definately better and no random hang up or button pressed so far... Please provide feedback!!!
Thank you for this useful information. I have a Sony Xperia V lt25i.
After display exchange, the proximity sensor always indicated "near" which resulted in black screen when using the telephone.
Anyhow here is what I did to resolve it:
- backup pics
- root phone using towelroot.apk
- install supersu
- install fx explorer
- install fx explorer root addon
THEN:
use fx explorer
... filesystems --> /system / --> root tools -> mount read-write
then go the file
/system/etc/hw_config.sh
and edit textfile
I changed the threshold from 5 to 9
val_threshold=5
then save file
... filesystems --> /system / --> root tools -> mount read-only
