I've seen that the Xperia S has light ambient sensor, but i cant find the configuration to enable auto screen brightness.
Any idea how can i enable it?
I don't think there is a setting for it there wasn't on my arc either
hmm i have read that the auto brightness function is enabled by default, but i dont notice any brightness changes when i enter to a dark room or go out in the day, auto bright function doesnt seem to work.
Anyone can confirm this?
On my SGS2 with CM9 it is under Settings --> Display --> Brightness.
I dont know where it is under Sony ROMs, but somewhere around Display or Energy Saving maybe it has to be, I couldnt imagine that Sony would take out this...
If you want to test it you could light with a lamp direct in the sensor or cover it, then it has to change the Brightness.
you set the lowest screen brightness you want, then the phone does the rest

not working, just tried. I set my screen brightness to lowest then i put in standby, i went out to the sun and when i turned on the screen and unlocked the device i couldnt see anything.
Also tried with a lamp, doesnt work either

Well, if you manually set the brightness to the lowest setting you are gonna get a dark screen. Obvious thing is obvious.
I've recently been to Sony Mobile's headquarters in Redwood, and I got all the details about this explained to me.
The way it works, is that you can manually set a "preferred level" of brightness, and the phone will automatically vary this setting but not stray too far from it. The default value I believe is 50%.. I don't have exact numbers for how much it will differ, but the auto backlighting is there.
I also asked if Sony will add a manual override to this setting in a future FW upgrade, and they said that they might
SEARCH before you post!!! Already discussed (and how to enable it)
It's enabled via the screen brightess toggle. One option is Auto.

I just installed Android 2.1 and rooted it. In the brightness setting there is no longer a selection to choose the Auto-brightness setting, just a slider for low and high brightness.
Also I noticed the Power Widget that has the brightness control switch lets you switch between low, auto, and high, but while in Auto (the dimmer setting while the button is ON), the sensitivity is very poor and will only brighten the display by about 10% while moving from a very dark environment to a very bright environment.
Yup, i agree. This sucks. Although i had forgoten how nice everything looks with the brightness turned up. All the same id like to have it back.

cant expect everything in 2.1 to be perfect. Yes it has taken them a while but i wouldnt expect it to be without any flaws!
At least we got it finally. WOOOOOOOOOOOOOOOT

I thought this today too but the Auto Brighten IS there and still working, just a bit differently.
Initially you choose the 3 levels of brightness on the quick select from the 5 widget icons. This is the brightest it will go, but if you go from a dark or light room it DOES indeed still adjust.
I noticed this after a bit today just standing in the kitchen watching the movers do their thing at my old place. The sun was ducking in and out of the clouds and the auto function was working fine. I tried it in all 3 modes, the only one it doesn't do anything in is the least bright mode...the one I noticed it most is the middle bright mode.
So YES, it is indeed working, just differently.
The auto Brightness sucked in 1.6 anyway. It was never that good for me. I use a brightness widget to adjust it.
I much prefer the way it works now. Seems to be a lot more user friendly tbh
have you tried the setting in spare parts (from the market)?
I've not tried it myself, but I know the auto setting is there.
Auto birghtness
Hmm. I have the 2.1 update and I have set the brightness to the low setting in the power widget. The brightness still adjusts automatically, and I don't want it to. I want it to stay at a low level all the time to save my battery. How?!
It's either missing for me or I can't find it after updating to 2.1. Any ideas?
They removed it.
My first suggestion would be to use the search function on the forum...

You know, I've seen a million posts just on this forum that say "Auto Brightness is now in the widget" and "Auto Brightness is always on" and now you're the first saying it's gone.

Because if you actually use the widget you will see it isn't "auto" its preset. Off Mid Full.
From what I can see, especially when using outdoors, the brightness level you set in "settings" determines the minimum brightness level.
Whereas, the actual brightness level is equal or higher than the minimum dependent on background light intensity.
Try to test it under sunlight, cover the light sensor then uncover it, should work.
Auto brightness is present. Its on the widget with your wifi settings. The brightness widget has three settings low, auto and high. I have tested it several times and the phone does respond to light and does get brighter. It seems they changed the sense algorithm for it. But it works, just not like it used to.
EDIT:
Here's a quick way to test, if you have desk lamp that's florescent you can set the widget to the the auto setting (second option). Unlock the phone and hold it up close to the light, if done correctly you can even see the text on the phone get gradually brighter. Now quickly cover the sensor and you will see it dim. You can use direct sunlight as well in the same idea.

Exactly. In the auto setting, you can adjust the maximum level in the settings, like it used to work.
To all those saying it's gone:
PUT IT UNDER A LIGHT! It's not that hard to see for yourself
Use the widget, set it so there is no green bar under the brightness, then press it once.. it will then get brighter on its own in bright light
Does anyone have a solution to auto brightness issue?
Even in the darkest room, the lowest light level is "medium" and not low! Its excellent setting when using phone outdoors but in dark room or at night its just too bright. Is my phone broken or is it general windows phone setting?

on my titan, the auto brightness behaviour is erratic and sometimes goes too low.
the camera is one of the issue triggers. after every return from a photo session, the screen goes to a lower brightness.
also, sometimes it happens when unlocking the phone but i don't know what triggers it. then suddenly the screen would return to its normal brightness after a few seconds, although not always.
i suppose it's a driver issue...

so you get the autobrightness to go as low as 'low' set manually? - I tried it but even after camera the lowest brightness I am getting is same as 'medium' when set manually!

no, not that low only lower.
but you are right, even in complete darkness the screen won't go to its lowest setting...
Yes same issue here.
Automatic can go a little bit lower than medium, but not much. Too bright in dim environement.
For general use, i would like to have a preset between low and medium
Since these days many people like ultra bright screens (and ultra loud sound) i am not sure HTC will try to fix this "issue".
I just hope Microsoft can add a brightness slider in the future. (Or bility to set the min auto and max auto levels)
Btw, do you know why camera mode go into max brightness ? This is a little harsh indoor.

Yes that behaviour is very strange too! I think it's present only in the Titan. Some other windows phone manage the camera brightness a little better. But then I think increased brightness while using camera sort of makes it little pleasant when using it outdoors. But indoors as you mentioned, it's a bit too harsh brightness!
I think it's the light sensor that doesn't work properly. Some places/forums mentioned about issues with various HTC driverseven after those 2 softwares updates we received in Nov-early Dec.
In daylight,the auto brightness works wonderfully for me,I never change it.
But in a fairly dark room,it's too bright and most of the time,I set it to low
I usually set it to medium... and set to low by myself by night.
I have sent a message to HTC (via theirs contact/ticket system) about the "can be improved" auto brightness, and "camera set brightness to max" issues.
Better than nothing.
Since this is a easily reproductible problem, maybe they can take a look if they receive several messages about this.
I wonder if the screen going to max brightness with camera may have something to do with the "HTC Camera modes" addon ? (who knows..)
But i don't see how to remove it. I even can't find it on the marketplace (under HTC section).
I have same issue, I get blinded when I check the time on my phone at night
It was there even before camera modes update was applied by HTC. So unlikely

Obviously, the brightness go to max too when using skype with video.
Hope they will notice and fix it.
Trying to talk to HTC customer service is especially unhelpful here in france.
They have absolutely no knowledge of theirs WP7 products

Now that we have unlocked roms, any way to tweak the auto brightness ?

I've tried all 4 ROMs and they have the same behaviour as stock ROM at the moment. But it might be useful looking into the registry threshold values. I know there is some sort of home brew app that lets us set the volume increase in 10s, 20s, 30s or 50s. So a regedit might be somewhere, will dig around myself since you've reminded me again
Auto brightness... What happened? It used to just work. You know, automatically. If you adjusted the slider it would snap out of Auto mode and lock to what ever you set it at. Going back to full auto was a s simple as selecting the checkbox again in the quick settings.
I don't know if it's part of Marshmallow or TouchWiz but now the brightness slider controls the automatic-ness of the brightness. So its more like a auto "range selector" or "sensitivity selector" it seems. Its more of a semi-automatic mode.
If you set it to ~50% the brightness will adjust +/- 10% around that setting. But it doesn't seem to just automatically do 0-100% on its own anymore.
Set it near 100% and it'll practically refuse to dim in low indoor lighting.
It also seems to respond to whether or not you're holding the phone. It'll get brighter no matter what (thankfully), but it will not lower the screen brightness until you put it down on a horizontal surface... Kind of annoying if you're reading and happen to walk in to a dim room and you're being blinded by your phone until you put it down and then pick it back up. I have Smart Stay turned off so that's not it.
I definitely prefer the plain old, dumb, just works, auto-brightness that I could snap on and off if I needed. Now its...complicated. Why "fix" what isn't broken. Was it confusing some people?
I tried Lux Brightness control app but I'm not sure it's really what I'm looking for. It's too much. I just want "set it and forget it" Automatic (0-100%) brightness like it used to be.
It's a feature. The brightness slider will now bias the automatic setting toward higher or lower brightness while still maintaining the automatic adjustment functionality. Turn off the automatic setting check-box to accomplish full manual control.
What ever happened to just plain Automatic? I don't want to have to mess with a slider. It adjusted the brightness fine before. I find that now it's either too bright or too dim for many situations and I'm constantly messing with the slider. Whereas before, auto was just auto.
Same problem here... It is very annoying

Interestingly, with my old s3 and now my current s6, when looking at battery usage, the screen was always about 15% and usually the second item in the list of things that use the most battery power. It was what I always loved about amoled. Now, screen is number one and comes in at ~50% after the marshmallow update. I wonder if it's because it's always so bright now? Or perhaps they've changed how battery usage is measured. Not much I can do about it. Just an a interesting observation.
So when you're outdoors, even if it's overcast there's no way to slide the brightness down (It auto-snaps to full brightness) even though it's not needed.
I have situations where i could easily use half brightness but my phone forces auto max light
YES, I know i can disable auto brightness completely, but that would not be convenient.
Any fix for this?
I use an app called Lux. Tons of options with it.

Hmmmm, Im not sure how it works but it does have an auto mode which you can tweak on the fly.
I have noticed that also. It also jacks up the contrast to make it easier to see.
It makes pics you took look terrible when viewing them outside. I had to learn to NOT delete them until I check them indoors. I assumed some pics I took were crap at first, but it was just the jacked screen contrast that made them look bad.
On my S9+ in bright sunlight it happens that not only something happens to the contrast and colors (eg. reds become somewhat pinkish) but also black elements on screen start flickering/smudging while scrolling. It looks like the device turns into some sort of brightness boost mode.
Does anyone else experience anything like that?

That's exactly what happens to me. Also if you slide the screen you can see how it the colors are totally distorted.

Check out the screenshot. There's an option to enable brightness slider in the notification bar. Becomes easier to adjust brightness just by sliding down the notification bar.

Did you read what the problem is? outdoors it snaps to max no matter what. (Unless not in auto mode)
Any solution for this problem?
Turn off auto brightness when outdoors..
Guys I've noticed that even if you turn off auto brightness go out in the sun and turn the screen up to max manually,it will kick up into super brightness mode or shine a led light at the sensor when indoors simulating the sun,just like it does with auto brightness on.sammy really want us to get burn in I think so we have to buy new screens all the time?

Never had a screen burn in on a Samsung phone. Don't worry
Guys, idk if this is a S10 only feature (or Android Pie), but when I'm on that situation, if I lower the brightness slider and leave it there for a second or two, the brightness will actually stay down and not jump back up again. Worth a try.

After the S9+'s update to Pie some of the old settings get copied to the new OS, but if you don't go into the settings and check, things might not be configured correctly - I had to choose a different setting and then choose again what was previously selected to ensure that it was written into the Settings correctly.
With the new update the "Automatic Brightness" applies to the AOD - see here in this screenshot, my search of the Settings for the word "auto brightness", see what comes up in attachment #1.
What you need to do is go to the "Adaptive Brightness" and turn it on, then manually adjust your brightness under a few different conditions (EG: Indoors lights off, outside and overcast, and bright sunny day). Now your phone will understand what setting you want for different conditions and automatically adjust the brightness based on lighting conditions, see attachment #2.
The "auto brightness" is now used for the AOD, and has nothing to do with brightness when unlocked. The reason it "auto snaps to full brightness" is likely because previous settings were just copied over after the update and you haven't setup (and trained) the new "Adaptive Brightness" for various light levels. The AOD has both "Auto Brightness" and double-tap the clock to adjust AOD brightness.
