How does this work given the camera is usually inside the phone?
I'm pretty sure the phone doesn't check the light through the selfie cam but through a designated sensor. Could be wrong though ?
No phone checks the light with the camera.... It uses a brightness sensor as any other phone too.....

I've been working around the light sensor and with the available reg. hacks on this forum. I could not find anything that could make a difference.
Is it for real this sensor? I tried to focus a strong light towards the sensor and other times remove the light, the dimming and the device light is just the same!
I reckon technecally the light sensor should dim under high light beam and back to normal under dim light surroundings!
Works on mine. You definitly have it turned on in the power settings? I find it works best if you put your finger over sensor in bright light.
Thanks for the tip. But couldn't figure out anything that could've worked! Could you be more specific? BTW the settings under "Power" is all to default.
under Start>settings>system>power>backlight tick the box 'Auto adjust backlight'
I need an app that would switch off my galaxy tabs screen whenever I shut the case (its a book-type from SGP). I assume the light sensor would do this just fine.
Any apps out for that?
Surely that would make it impossible to use your device in a darkened room or outside at night? Wouldn't the screen keep turning itself off?
Hmm, I didn't think of that. Any suggestions? Maybe the magnetometer or front camera?

try this if it works ...
My Galaxy S has a problem with the Light Sensor, every time i make a call my phone freezes or black screen, I tried running some sensor tests but also does same when i try the light sensor, so that must be it. have this problem for a year, at first i thought it was the proximity sensor.
When my headphone is plugged in, i dont have this problem because the light sensor wont interfear then.
I want to disable the startup of the light sensor,
I already setup ADB, so im ready to push and pull, but i don't know wich file i need to edit. remove a # here and there
Can anyone tell how wich file it is?

Sure its not the proximity sensor? Cause I got the same problem. When I accept a call screen goes black, the upper bar is visible and after a while the screen turns off. Im ceratin that is a problem with the proximity sensor or not?
Same here, yeah think its the proximity, but my light sensor also doesn't function properly, auto brightness adjustment doesnt work also.
Very anoying problem.
I have checked on an app and it confirms that we don't have a light sensor
Nope. We don't have a light sensor. When me and another user mentioned the brightness changed automatically, i think the brightness just went to the lowest because the phone couldn't detect any light. When i put my phone under a light the brightness didn't go up.

Yup you are right
It does that brightness change automatic sometimes but that has no relation with light sensor
WE DON'T HAVE A LIGHT SENSOR
I was playing around with my phone and i was checking to see if all my phone sensors are working and turns out the light sensor isnt..
Care to explain how sensor isn't working? Hand on sensor(pocket mode) the screen won't turn on with correct fingerprint? Slightly covering the proximity sensor screen dims? Is auto brightness on? Doesn't help anyone help you just by saying it doesn't work. It is all in the details
So OP, you did the hardware diagnostics and it shows that the light sensor isn't working?
