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).
Hello!
I wonder if anyone had this issue. Yesterday suddenly the backlight of my XT894 started to act weirdly. When i pressed the unlock button, the screen would go very bright and then shut off after 2-3 seconds, but I still could swype the unlock screen and hear the unlock click, even with the dark screen. With a little bit of external light I could see the image was there, but the backlight of the screen was not on. I went on to the power shortcuts and disabled the Automatic brightness control, and as soon as I did that the display turned on, very dimly but it turned on. When I set the brightness control to maximum, it still is very low. If i set the brightness to minimum, its almost impossible to see anything. In display settings, the automatic brightness is unchecked and the brightness fader is set to maximum.
I started suspecting the light sensor, so I went ahead and downlaoded a sensor tester app, and the light sensor appeared to be reporting the light levels correctly - low readings in the dark, and much higher readings in direct light.
Is my phone backlight dying? Any idea if this might be due to defective mainboard, or the display itself?
I already did some repairing on the phone myself, so I am comfortable dissassembling it and changing parts. Few months ago I changed the main board because my old one had a broken usb connector, and it worked fine until now.
Any advice would be greatly appreciated!
Thank you in advance!
Best regards,
Konstantin
If I remember right, by default, the maximum auto-brightness is still lower than actual maximum, so if the screen can barely be seen at manual max, it makes sense that the screen is pretty much unviewable with auto on.
Idea:
If you have it installed, boot into Safestrap and see if your brightness is normal.
If not, pull up the diagnostic menu (hold Vol - while powering on iirc, might be Vol - and +).
If your brightness is normal in those, it's probably something gone wonky in Android. If not, your screen backlight might be going and needs replaced. I don't think there's anything on the mainboard that would cause it, aside from the circuitry actually supplying power to the backlight...
Screen replacement actually isn't terrible for the D4, if it comes to that, since it's not fused to the glass (like certain single-piece phones for example...*sideways glance at the S3*).
Hello!
Thank you for your reply!
Effectively something is very wrong with the device. Today I woke up to find it completely unresponsive, had to turn it off by holding the power button for a while. When it turned on again, the whole screen was white with glitchy color lines since the very reboot, and nothing else happens, couldnt even turn it off without unscrewing the battery.
I will put the old main board to see if the other one died.
Thank you again!
Best regards,
Konstantin
There are some occasions where my screen just isn't bright enough. I turn off auto and set to max. However, when I expose the light sensor to direct sunlight it brightens further. Is there any way to make the screen that bright all the time?

Hi ,
As far as i can remember ,there's a good reason
Samsung"configured" it that way .(you described)
Think in terms of"screen burn in " (Damage to your screen etc )
Not good for your device.
Good luck

If your display is set to Adaptive Mode, your screen will change the screen tone (including white) based on your surroundings, just like the True Tone feature on the iPhone X.

Well, I have A6 plus, but I don't have experienced like what you wrote. I can only making it manual in Adaptive Mode. Do I need switch on/off something to work it automatically?

Well, the screen tone changing is barely noticeable unless you compare when you go from one place to another. I have my screen mode on Adaptive Mode and the full screen color balance is on the middle.
Thank you. Also what I don't understand, if I'm using other screen mode like Adaptive, and when I switch on the Blue light filter, it switches back to Adaptive mode with that tiring vivid colour. Why it's just don't apply the Blue light filter in the applied Screen mode? Meh...
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...
