I am currently running JPA/JPB Hybrid firmware and I was wondering if there even is a sensor for the auto-brightness.
Normaly I have set my brightness to the lowest level, which is enough for indoor usage. But as soon as I am outdoors in the sunlight I can't even tell if the display is on or off with this brightness level.
Now the strange thing about this is that it does not seem to make a difference whether you check the "Power saving mode" in the Display settings or not - the Display brightness always stays the same:
- with the highest level it does not get darker in very dark rooms to save battery
- with the lowest level it does not get brighter even in direct sunlight, which makes the display unusable
On the left of the Samsung-logo there are 2 "holes", I guess one must be the proximity sensor and the other one the brightness sensor?
Is there any way to have the brightness on a very low level in dark rooms and on a high level in bright rooms / outdoor WITHOUT switching manually? Even switching with a widget sucks, because outdoors the display is so dark that I can't even draw the pattern to unlock the screen first (at least not without covering the display from the sunlight)
If there is I think the driver is missing so it's useless.
There is a brigness sensor, not for auto adjusting the screen brighness, for example try *#0*# and press sensor, now if you put you finger on the sensor, you phone vibrates, it means it is dark, if your finger is not on the sensor, it says, its brighten outside, that is for example to telephone, the screen goes dark, when you put the phone to your ears
"that is for example to telephone, the screen goes dark, when you put the phone to your ears"
No, that's the proximity sensor, and I think there is no light sensor in SG3, because that test app shows only proximity, accelerometer and magnetic sensor.

Power Saving is not for dynamically change the strenght of backlight. It's just turning to lowest level when your battery is 15% and less.
And there is 2 holes, for proximity sensor. Try to cover one hole, and it doesn't work. Why? Because 1 hole sending an infrared (I think...) wave, and second is receiving that back, from eg., your hand.

totaly makes sense - thank you very much!
Hello gays,
I have problem with my light sensor on P8. Time to time, when I've light my display it doesn't switch automatic brightness, stay on minimum illumination. Wen I turn off display and light up again, there is normal brightness??? Does someone know what can be done?
Hi,
My screen is always dark with light automatic or manual... And my screen stays black during/after a call.
I have to put the light manual with high level to have a readable screen.
Which sensor is in cause? Light sensor or proximity sensor?
Thanks.
The notification LED gets very dim in low light as it follows input from the light sensor. I have disabled auto brightness and its still same.
Is there a mod for having constant notification LED brightness ?

You know I thought it was me I noticed it seemed brighter at times.
I know in settings there is led control somewhere But I never noticed a setting like that
i recently bought a used s7 edge. the cellphone's display is damaged buf overall it works fine. except for a few issues mainly related to light sensor according to my understanding.
1: the display flickers when auto brightness turned off or when brightness is set to anything less than maximum
workaround: i installed screen filter app to control the brightness
2: the screen goes to green screen of death when device is put to sleep
workaround : turn AOD to always on and never Turn it off
3: the display goes to green death screen during call and wont get normal unless call is ended and screen is locked and turned on..
4 : at AOD ,the screen flickers at night time or in a dark place but gets back normal in bright light..
info i need : i thought what if it was possible to change the android framework values for the light sensor so that no matter whatever the light of the surrounding may be.. the device will always think it's in bright light.
for example if the settings for current values are
high 5000 medium 2000 low 600
then i change it to
high 1000 medium 500 low 25
so that the device will always think its in full bright area..
can anyone help me in achieving this goal? thanks
