Adjust or set the brightness manually until the problem is resolved
first i am very thankful to you for reply , you are totally awesome , again thanks for joining xpiera ray forum (i have seen all your posts , so helpful)
I have tried , but still not working
Lemme explore it
Once i have CM7 installed , i go to settings and set brightness to full
then use my device it works good
After i lock it and open it again i find brightness it reduced to half
i go to settings and check it , it shows brightness is set to full but in reality it is not
is there any problem with my bootloader unlocking method ?

It may be a problem with cm7, have you asked in the cm7 thread ?
The brightness works on my the miui roms
Not sure why it doesnt on cm7 so may be rom specific so report on that thread and see if you get any feedback. it may be a known bug
one more question chiefy009 , which miui is best for ray?
and is overclocking not harmful and much battery consuming
Planing to shift on miui

My miui has tweaks for smoothness and extended settings but try them all.
Overclocking does use battery so undervolt as well, undervolting is trial and error to see if your phone remains stable
Overclocking to high could damage the phone if used over a prolonged period of time I would imagine but a quick google search will get you more info

i had this problem to solved using this guide! if is not working with the file edit, use the als_curve.ini (backup first)
I have this in CM 7
# LMU AS3676 Configuration

echo 1,65,255,24,24,5,128 > $dev/lcd-backlight/als/curve # ALS curve for group1

echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 450 > $dev/button-backlight/max_current
Last time i changed the whole code , now i think i have to only change
echo 2,0,0,0 TO echo 0,0,0,0
right ?
i replaced lights.semc.so with stock lights.semc.so file , in system/lib/hw
brightness works but only problem is LED light always turn on , in pink color

That's right, only change the "echo x,x,x,x" phrase.
I tried "echo 3,2,2,0" and "echo 1.5,1,0.5,0 30h". I dont realy know what these parameters exaktly mean, but "echo 1.5,1,0.5,0 30h" works fine on my ray.
You also can change your als_curve.ini in system/etc.

Do you mean the flash LED on the back? And does it keep the brightness you set before you locked?

Hello xutienan9520,
could you please explain me the difference between
"echo x.x.x.x" and "echo x.x.x.x.x.x.x", i`m noob as f**k.
And what kind of effect does "echo 0.0.0.0.0.0.0" have to your brightness?

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.
Code:
#!/system/bin/sh
#added by emannxperia on 19 Sept 2012
if [ -e /sys/class/leds/button-backlight-rgb1/brightness ]; then
echo "1" > /sys/class/leds/button-backlight-rgb1/brightness

if [ -e /sys/class/leds/button-backlight-rgb1/max_current ]; then
echo "1" > /sys/class/leds/button-backlight-rgb1/max_current

if [ -e /sys/class/leds/button-backlight-rgb2/brightness ]; then

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

Use at your own risk, i am not responsible for anything happening to your device
What it does
This flashable zip turns your button backlight off permanantly.
it just changes your hw_config.sh file to disable backlight.
Steps
for your own safety please make a backup, in case something happens.
reboot into cwm
flash the zip
Downloads for bbl disabler.
active
lww
mini
mini pro
ray
If u want to get the light back,
active
lww
mini
mini pro
ray
in case it didn't work, edit your hw_config file found in system/etc
find this line: echo 1 > $dev/button-backlight/max_current
and set it to
Active: echo 8000 > $dev/button-backlight/max_current
lww: echo 1500 > $dev/button-backlight/max_current
mini pro: echo 500 > $dev/button-backlight/max_current
ray: echo 50 > $dev/button-backlight/max_current
for mini find these two lines
echo 1 > $dev/button-backlight-rgb1/max_current
echo 1 > $dev/button-backlight-rgb2/max_current
change to
echo 8000 > $dev/button-backlight-rgb1/max_current
echo 8000 > $dev/button-backlight-rgb2/max_current
okay
I have an easier way
put it in init.d
Code:
echo 1 > /sys/class/leds/button-backlight-rgb1/max_current;
echo 1 > /sys/class/leds/button-backlight-rgb2/max_current;

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

Is there an app that lets you set the distance for the sensor for our device?

AndroSensor-App keeps showing 1cm as distance - can somebody verify this value on other kernels or other Roms?
1cm seems too little distance for my ear...
i get the feeling, i'm the only one, having this problem...?
:crying:
Found this:
https://github.com/rachit-rc96/Vengeance-Kernel-U8500/blob/master/drivers/input/misc/apds9702.c
According to my amateur-interpretion of this link, the settings for the sensor are stored in the kernel?
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
echo $val_filter > $dev/filter # RFilter. Valid range is 0 - 3.
fi
to :
Code:
# Proximity sensor configuration
dev=/sys/bus/i2c/devices/2-0054/
val_cycle=3
val_nburst=0
val_freq=2
val_threshold=2
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.
echo $val_threshold > $dev/threshold # sensor threshold. Valid range is 0 - 15 (0.12V - 0.87V)
echo $val_filter > $dev/filter # RFilter. Valid range is 0 - 3.
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
restart phone
try or use the app: Phone Tester
ENJOY

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
