i have a problem with light sensor. sipmply is not working.. when i turn it on the screen goes to lowest settings.
I installed the "water level" program an i see that there is always at 926 lumens. any idea whats wrong?
i try hard reset but the problem persists.
What I did for it to actually start working was I put the "On battery power" all the way to power save, and then selected "auto adjust backlight.
I might look stupid here, but my screen goes dimmer in a pitch black room, and brighter when there is a lot of light. Is this how it works?

That's right - if the environment is darker you don't need that much backlight for the screen to be readable. The more light is shining at the display the brighter it has to be in order for you to see anything. It's really more of a power saving feature...
for the record:
i return my device as DOA and now i got a new one that is working fine .
I have been noticing that my auto brightness doesn't work like it did when I first got my phone a few months ago.
Back then it seemed like it changed brightness after a few seconds when it should.
Nowadays it doesn't seem to do that anymore.
Now if I hold my phone close to a bright light, hit the power button and unlock the phone, the screen is very bright, as it should. When I hold my phone in a dark place, it doesn't adjust the brightness. It keeps being very bright.
BUT, if I hold my phone in a dark place and hit the power button and unlock the phone, it's dark, but when I move my phone to a brighter location it does make the screen brighter.
I first thought this had to do with CM, but now on stock froyo it does the same thing.
Is this normal, and am I just mistaken? And should the phone adjust the brightness when I hold my thumb on the sensor thats just right under the power button on the front of the phone (I expect the screen to be less bright)? Because it doesn't do that.
Thanks in advance.
No it's not normal, mine reacts to changes in ambient light in a second or 2 (FRF50), just like yours used to.
When I cover the light sensor with my thumb, the screen dims right down.
Thanks for your reply.
Is there anything I can do to check why this doesn't happen on my phone?
Can I perform a check on the status of my sensor, on it's behavior?
And are there any known reasons why this could happen?
Thanks in advance.
This exact issue is happening with me ever since I updated to 2.2. It worked perfectly before but now I notice that once the screen adjusts to maximum brightness in a well lit area, it never dims....don't know what the problem is. But I hope there is a solution.
Good to hear I'm not the only one with problem, that gives me hope this might be a software issue rather than a non-working sensor.

Actually I may have to take this back, in retrospect, the dimming actually could have been the screen timing out.
When covering the sensor with my thumb and not having the screen set to 15secs, it doesn't dim until I lock/unlock the screen.
Reading on another forum this is by design rather than a flaw, as people complained the screen would fade in and out in certain light conditions... now it can't.
Ah, okay. Good to hear.
Thanks again, Rusty.
froyo seems to fix the autobrightness for me, at least now i can see the screen brightness is changing according to lighting condition, previously i don't notice it (using cyan ROM prior to froyo).
hi guys. i recently replaced my cracked screen and after that i noticed that the auto rotate function isn't working properly. some times it's ok but sometimes like when i go to camera, and when I come back to menu, the screen is Locked on landscape mode and the only think I can do is to lock the device and unlock it to make the screen portrait.and after that i cant change the screen orientation att all unless i restart the phone.
Mostly the screen has a light that only noticeable in the quite dark place when the auto screen light is on after turning off the screen.
i had some problems with ambient light sensor and proximity sensor as well.
i once wiped the data i was thinking maybe it's a software problem but nothing changed
is it really a hardware problem? is the board or any parts damaged during the replacement?!
Same problem Here
I have the same problem, but it is with ambient light sensor and the proximity switch, when i go to the service menu (*#*#7378423#*#*) the proximity switch does not show up, when i press ambient light sensor it says ¨This device does not support this function¨.
This phone i just bought it a few this ago, i tried reseting customization, wiping data, flash another rom, Root... everything and no answer.
If u wipe and flash and still have the problem it is possible you have a hardware problem. Check all of ur water damage indicators to see if they are red. Also you could tell us your model.
Ok guys so I need to know if there is a sensor issue with my phone .I don't use auto brightness no more because if you go in the sun the brightness overrides itself to brighter than max brightness and it is the reason why I've had burn in 4 times so far and had to get the screen replaced. But I've also noticed that with auto brightness off but you have the brightness maxed out and go in the sun or shine an led torch at the sensor the screen will kick up to override max brightness sun mode out like when using auto brightness. Is this normal behaviour. Can anyone test this fpr me please .only 6 months left of warranty left
So if this is a feature its stupid ,and make sure you never put your phone on max brightness in manual or autobrightness if out side and it's sunny as it will kick in and cause screen burn .
I've factory reset it and cleared cashe still the screen in manual mode if maxed out in the sun with the brightness maxed out will auto ride to super max brightness mode .im on the oreo uk fm
Phone is uk unlocked note 8.
Anyone? I see lots of views no replys I'm sure everyone that view this thread owns a note 8?
OK lol thanks for the great respone guys smh this place sucks :good:

No, this place does not , if you do not get any response , it means nobody has something useful to share, beeing rude will gain you a ban
Maybe your the only person that has this error, so no one has any advice to give other than to factory reset (which you all ready done).
Most people has moved on to other phones. So you'll have to be patient. I say is take it to the Samsung store and see if it is covered under warranty.
I'm not the only person all note 8s do this i think but nobody in this thread owns a note 8 or 9 other than me because they both do it. On both my phones.its a terrible feature as it will cause burn in.if you want to be able to see the screen outside in the sun
So i've been using auto brightness for 2 years, i don't have any burned screen. Last week I've been using phone on sun, taking a lot of pictures (brightness set to auto, on camera app its option to set it to max bright) and still no burnout. I think you should say your problem to guy who will accept your warranty next time
Well this is good to know just went to the sammy service centre and tested the phones they had there with my led torch and they all do it including the s9 plus .so it maybe always was like that or it's been added into a fw.

I will add that friend have a s8, his screen is good. Also another friend had note 8 and now note 9, always autobrightness on, no problems so far.
I have a little experiment
1st, I set auto brightness on, turn on a torch on the sensor, brightness go to max, then turn it off, and brightness go to middle (room light on)
2nd, set the auto brightness off, slide the brightness to minimum, turn on the torch to sensor, and brightness remain to minimum, nothing change
So I assume maybe it's a software feature I don't have, you can check with your friend running the same firmware, or you can check using *#0*# on keypad, click on sensor, look for light sensor, and do a simple test, see how much lux you have when you're on direct sunlight, or in a room, then you can flip your phone down / reverse the light source, the lux sensor must be read it on continuous count, as you flip your phone, the number will get decrease
I hope you understand what I am saying, because English is not my native language

You did the test wrong friend you need to turn off auto brightness and slide the brightness slider to max brightness it must be fully maxed .then shine led torch at the sensor then the brightness overide kicks in and goes even brighter just like In auto brightness mode.but if the slide is not fully maxed it won't do it

Interesting you mentioned all devices do this before you went to the service centre and confirmed it. That admission renders your entire post pointless. If all the devices does this, it means it's not a fault on your sensors or anything on your side, and it means it's indeed just a feature.

I said imo that all devices have this issue. Because bothe my note 8 amd 9 have the same issue .and i found a thread on reddid where 2 others also had the same issue.its not a feature because it can damage the screen it must be a software bug that Sammy need to fix

Ah I see, after doing that, I found out that the screen goes brighter and the colors seem to be fade out
Maybe it will help us to watch better when we got under direct sunlight (I think it's not a bug)
But in real life usage, I have my adaptive brightness turn on, then when I think it's too much bright at the moment, I will manually adjust it to my desire brightness
So that the system will learn the pattern and will apply automatically next time I had the same condition
Doesn't do that with mine and I live in Hong Kong.
If I keep the brightness to the Maximum, I notice that in bright sunlight/extremely bright indoors, the screen gets Automatically even brighter and dims when the phone notices the environment is not that bright !!!!
You can experiment by shinning a flash on the top right side of the phone with slider on max brightness.
Isnt it stupid – When the user have disabled auto brightness or any power saving modes the phone keeps getting bright and dark
I cant believe Samsung has let it pass this to the production models…
@craige
I think it is intended as you see there's a color RED at the far end of the brightness scale, and that's signifies the most extreme situation the screen can go, which in prolonged use may damage he display. But still, it can provide a elevated readability when you are out under sunlight... And return to safe margins so as to prolong the life of the display...
