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

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 guys,
To save battery thru screen use as much white background as possible cuz LCD Screen uses White pixel backlight and white will use less battery,, it's the complete opposite of amoled screen while they use black pixel.
To save battery more turn on gps but device only, cuz the Google play services (locations)
Use the wifi and network to share the location, so leave it at device only and the GPS will be offline until you use an app needs GPS
More tips I will share,
Thanks
this with lcd screen is bull****. only way to save battery on display is to set brightness down.
backlight for the whole screen makes the light, not the pixels itself like on amoled.
He actually is true but the effect is so low it doesn't matter.
To Display a black (or dark) image the LCD needs to block the backlight (which is always on) and this in fact requires more energy than letting the light pass and displaying a white screen.
So mine turns pink/reddish when setting the lowest brightness setting (ambient display on) - you have to be in a pitch black or very dark room.
When its off, it still does it but its not that bad.
EDIT: If yours does turn pink, will you RMA?
Mine does this as well. I rarely ever see the brightness go that low so it doesn't bother me that much. However what does bother me, is at 50% brightness unless i am looking at the screen dead center the screen has a redish, bluish, or greenish hue on it. Was very yellow the first day I had it, but the yellowish hue is gone.
I have adaptive on. Last night I set my brightness all of the way down. For the first time I saw a slight pink hue. Increasing the brightness fixed this. I am not sure if turning off ambient would have fixed it. If I see it again I'll try turning it off.
I thought was a known feature of amoled. I'm guessing they will all do it at low brightness.
Mine actually got worse. When I first noticed it, it was acceptable. Now its almost reddish already. Some people say its actually a feature of AMOLED. However, when I tried it on a different AMOLED Screen, Note 3 and 4 - i didnt see it.
No, I tried with adaptive brightness on and off and can find no color changes except maybe a slight blue hue when tilting the device and then almost rainbow effect at close to 180 degrees. Guess I got a good screen.
Hi all,
I dropped my phone (a very short distance about 1ft) but the phone was working ok.
Suddenly after 1 week, the phone display has Lines and out of colors display.
There are no cracks on the screen of any sorts.
But, if I use the lowest brightness, the display gets OK or the highest brightness the display looks OK.
Lines on screen and out of colors (distorted) comes in mid brightness and auto brightness.
any idea?
Hi,
I am using S8 SM-G950FD on stock android 8.0.0 from year+, all of a sudden the display on the screen has turned yellowish, i have tried the adaptive display option and changed the RGB to max and low and the settings for edge colour but the display is still yellowish.
Also noticed another thing: If the brightness is <50% the yellowtinge with black lines come up but if >50% then the display is fine.
I tried to click photos/ take screen shots but the yellowish is not visible on photo, but the dark horizontal lines on whitebackground are clearly visible. have not dropped the phone but this has begun suddenly.
when the phone is under bright light the automatic brightness increases the brightness of screen and the display is clear, when the phone is moved into low brightness the mentioned issue comes up
Any suggestions on how can i resolve this?
Any help is appreciated, phone is out of warranty. Is there any any replacement circular for galaxy s devices, like FOC?
