(Need Root)Enable Automatic Light Sensor on Xperia Ray

[hansip87]

What? I had to try it to be sure. Anyway, I have no proof that it really does nothing (I said "I'm pretty sure"), I could be wrong.

Maybe now it's more sensitive? I don't know since I haven't tested it extensively before. All I'm sure of is that the sensor already worked in the service menu, and that the screen brightness changed slightly even before the mod. Also, the light sensor still doesn't show up in test programs such as Z Device Test.

That's why I'm skeptical about this mod.

The sensor works, but no effect to the screen. That's what this mod fixes.

please update this to support .62 firmware please

It works with mine on .62 firmware. The last thing i've done is flashing new kernel from aire and edit the hw_config.sh like OP said. It is working. In fact, the transition is much smoother with .62 firmware..

Hi!
I modified my hw_config.sh and replaced my als_curve.ini with the provided. My sensor works great now, but since it's possible to modify one never get's satisfied!
So I'd like to know what to change to make the display less bright in dark conditions, and what to change to make it 100% bright in daylight.
And last, the stock backlight widget, does it respond to theese changes in the files or is it "pre-config."?

Great job btw with the hack!

Optional:replace als_curve.ini with the one i provide(is from arc):for me is better.

replace where??

Try to play with gain in the parameter value, the first digit one. If you want it more sensitive, reduce the next two parameter.

You must try it on direct sunlight to see the effect, try to close the upper right of the phone and reopen it. Works for me everytime..

At the updated op, you said you delete the curve file? Any replacement after that? Thanks.

Hi All!

I made the changes, but nothing happened. I checked the light sensor in the Service menu and it says:
Ambient Light Sensor
Value:0
No changes in the value whatever I do...

any ideas?

Strange:for me it worked,without als_curve.ini brightness change more slowly but seems to have more step..
Sorry for my english!

it works for me, brightness change more slowly....

- removing als_curve.ini
- set 1,1,1,0 in the hw_config.sh

thanks man

 

[slicksteiner]

Is als_curve.ini the same as als_curve.conf? followed the steps, removed the als_curve.conf then change the settings to 1,1,1,0 in the hw_config.sh.. it works! thank you! tested it by putting the phone near a light source such as lamp, or light bulbs and watched the screen go brighter and then removing it shows the screen go back.. and with the settings, the transition is almost unnoticeable
