I didn't replace the als_curve.ini file but modified the values in hw_config.sh Its working fine with my device. Thanks a ton. But I wonder what these values 3,2,2,0 are ?



Your phone does not have that .inf file now ?

hey..what values did you exactly change 3,2,2,0 to? I'm on 1,1,1,0 and doing see any automatic adjustment to brightness, unless i'm doing something wrong!

try 0,1,1,0 or 0,2,2,0...

check you als_curve.conf

change it's content to
Code: 
# Setup AS3676 ALS curve / group, y0, y3, k1, k2, x1, x2 
1,7,121,16,14,0,50

I have placed the two files from the first post to my system/etc as recommended. I restarted my device. The sensor it seems to be working when I go to Service Menu / Test of Ambient Sensor. But it does not work normally. I do not know how to activate.Automatic mode.

:( I extracted the two files from the new ZIP file and placed to SYSTEM/ETC no changes. ALS BRIGHTNESS app shows changes but still shows 000% of Brightnes. The test from System menu also shows value changes. It seems than AS is working, but it is not activated.

I've found the way to enable ALS on Ray:
Using root explorer Change this value in hw_config.sh(inside system/etc):
# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds/
echo 0,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 12900 > $dev/torch/max_current
To
# LMU AS3676 Configuration
dev=/sys/devices/i2c-0/0-0040/leds/
echo 3,2,2,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
echo 1 > $dev/lcd-backlight/als/enable #Sensor on/off. 1 = on, reg 90h
echo 12900 > $dev/torch/max_current​

Optional:replace als_curve.ini with the one i provide(is from arc):for me is better.
UPDATE:I've deleted the "als_curve.inf" from phone and changed
echo 3,2,2,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]
to
echo 1,1,1,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]

now backlight seem more"wide range".

UPDATE: New CWM version added(InstallazioneALS_Xperia_Ray.zip):flash via recovery.

UPDATE:In official ics 4.0.4 i found the best way is to delete als_curve.inf (after change echo 1,1,1,0 )

UPDATE 08/November: for a fast response (istantaneous dim change) flash (Fast Response)InstallazioneALS_Xperia_Ray.zip

I don't know how to install this MOD. I flashed the latest zip-file, but nothing changed :( Still no ALS. PLS improve the install-instructions!

Just checked file "hw_config.sh" from file "(Fast_Response)InstallazioneALS_Xperia_Ray.zip"

thera are different vaules, than recommended !!! Why?

file echo 0,7,7,0 > $dev/lcd-backlight/als/params

What is correcte? 3,2,2,0 or 1,1,1,0 or 0,7,7,0 ?
Is the second file "als_curve.conf" also correct?

The values influenced the speed how the brightness raise and decrease,so the right values depend on personal preference,0,1,1,0 is slow,0,7,7,0 is istantaneous..
I suggest you to try different conbination until you find your prefered

Unfortunately no effect, still not working.
Should be problem with kernel? But test of ALS in Service Menu shows changing of values.

To test it do in this way:
1)set brightness to 25-40%
2)put the phone under a bright lamp (or sunrise)
3)now with a finger close the light sensor in the top right corner of the phone
you should see change in screen dim..

YES, I went outsoude from building. There is very strong sun and it works. Only I am not sure how sensitive it is and what range it will do (0%-100%?).

    Hi arcatarc. I'm on JJ 3.2 rom. I searched this thread and you told, that in JJ's rom is ALS enabled by default. When i open hw_config.sh(inside system/etc) it shows, that:
    # LMU AS3676 Configuration
    dev=/sys/devices/i2c-0/0-0040/leds/
    echo 0,0,0,0 > $dev/lcd-backlight/als/params #[gain],[filter_up],[filter_down],[offset]

    Also i think its not enabled (it was the same on JJ 3.1). Or JJ enabled it by another way?

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

    echo 0,0,0,0 ... means that als is most wide range, lowest up response, lowest down response, and has no offset...
    first 3 values you can change from 0-7, the last one I don't know

    yeah, I saw it "working"... with a step or two at most. I am really disappointed by how SE implemented this. Even the brightness manual slider seams to have 15-16 steps, i.e. it's not smooth. I had a HTC Hero and auto-brightness/slider were flawless.
