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'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 have a problem after update on my auto brightness.
if i set auto brightness, and If I bring my note 3 from a dark room to a bright room, the screen is normal and get brighter.
but otherwise, if i go bright room to the dark room my note still brighter not dim.
Anyone else have this issue ?
sorry, if my english is bad.
check if light sensor works properly, type *#0* # in dialer and then tap "sensor" to see if the light sensor behaves properly.

Mine too, SM-N900 XSE-XXUDND1, maybe today I will rollback to NC1, DND1 looks bad.
Auto brightness Dark to Bright --> screen gets bright, but for bright to dark --> screen still bright, but after lockscreen it back dark again.
use lux auto brightness..best app ever..
I did a soft reset and wiped cashe that solved it for me.

exactly like me.
I've tried and succeeded, try to put the device on the table and close sensor with your fingers. This worked for me, screen gets dim.
but if you lift 60 degrees or more you device and close the sensor with your fingers, this not work again.
conclusions: auto brightness from light to dark worked if you lift device under 30 degrees.
i don't know this is bug or normal.
for Dark to Bright, the screen is normal and get brighter, although I lift my device 60 degrees or more.

Thanks for the advice and feedback , looks like normal, now I already stop using auto brightness, sorry for misjudging DND1 bad, actually DND1 is better than DNC1.
What am i missing regarding screen auto brightness? I keep having to manually change brightness when going from light to dark places even though i have "adapt to lighting conditions" ticked?
It feels like im wasting battery having the screen so bright at night unless i turn it down, then I have to turn it up again in the morning.. Some secret setting?

Same here, Someone said that the screen does dim but it does so slowly so you barely notice it! Hoever iam not convinced! Iam almost certain mine is not adjusting at all
For normal day light conditions i feel the auto brightness adjusts very well. Its definitely better than the s4 i had. I have the auto brightness selected and the bar at 50%. I agree for night time reading i have to manually adjust the brightness may be its not as quick to adjust in very low light conditions compared to day light
I was using CM11 on the S4 which had very good brightness control, not sure about standard. I agree during the day I don't have problems at all, and the screen is very good. It's just when I'm somewhere with low brightness and I have to turn it down, and then when I go back into day I have to turn it back up again. Pretty annoying having to change it all the time.
I will get an app to do it for me for now, but this must be some sort of bug this action couldn't be on purpose.

Go to service test and test it your self.

I find the auto brightness not very good.
Sometimes when the lighting condition does not change, it will start to increase/decrease the brightness to the level which does not suit the lighting condition.
It also have the tendency to favor lower brightness.
Thinking of trying out Lux Auto Brightness instead.

I don't know if you mean to test the sensor, but the sensor works absolutely fine (with other apps)
My auto brightness works just fine and i have mine on lowest possible setting.
Hi People
The Display Automatic brightness Not Working Anymore !
the display brightness doesn't change automatically anymore what ever the light condition in the room was.
in a dark room or bright sun the brightness is the same and not changing.
I have wiped Cache Partition but also nothing happened.
any body have any solution or a fix other than hard reset ?
Recalibrate auto screen brightness since Android 9 update
Since Andriod 9, my HTC U11 auto screen brightness was not working properly. It kept resetting to an almost useless 9%. There is a recalibration solution posted for Samsung phones that also seems to have worked for my HTC U11. Good luck.
With auto brightness enabled, tape your Galaxy S8 and cover the two sensors that are to the left and to the right of the earpiece.
This will trick the device into thinking you’re in a pitch black room.
Next, switch off the auto brightness feature by bringing down the status bar and moving the brightness bar to the left. Make sure you’re still covering the sensors!
Next, quickly activate the auto brightness feature and then deactivate it again. Keep the sensors covered.
Next, take your Galaxy S8 to a bright lamp or light. Stop covering the light sensors.
Put the brightness on your device to the maximum setting, then switch the auto brightness feature back on.
Your Galaxy S8 will now have had it’s auto brightness sensors recalibrated so that they work more efficiently in dark light, bright light, and everything in between.

Hello everyone
I've an issue with auto brightness adjust: the backlight is always too high.
When ambient light is very poor, the automatic brightness adjust keep the backlight very high.
I've tried testing light sensor using the built-in phone dial pad *#0*# and I've noticed that there isn't a light sensor(attached the sensor I've found)
Do you have the same problem?

I find that the auto brightness works fairly well. Not in all cases or circomstances. There are times the face is too bright at night, and too dim in the day, but it generally corrects it on its own. (I have AOD on).
Do note, that when auto brightness on, you can still adjust the "bias." For example, in your case, if it is ALWAYS too bright, even with auto on, turn down the setting for brightness. That should skew the overall brightness to always be darker.

I've already tried to adjust the "bias", but the brightness is anyway too high
The auto brightness adjust from 100% to 80% brightness level, also when there is poor ambient light
In the attached files I can't see the light sensor: can you try in your Galaxy Watch to see if you have listed this sensor?
