Auto screen brightness doesn't work?

When I have my nexus one set to automatically adjust brightness, it doesn't seem to do anything.
I can move it between dark and bright environments and the screen brightness doesn't seem to change at all. Am I missing something or is this feature not working on my phone?

It works fine with mine. I just clicked auto in the brightness setting. Make sure you didn't accidentally change it to a different setting with the settings widget that is by default on the first home page to the right.

works fine on mine yet not a feature i use....i just set it statically.

I find the auto-brightness to be too dim for my liking. It would be great if you could adjust the overall brightness while still maintaining the automatic scaling.

Turns out it does work, it just need to be *really* bright to make it change.
It doesn't change really at all in my office between switching the lights on and off (even though that's a really big change in light levels to me). However, if i go outside, it does get brighter.
As you say though, it does seem to be set a bit low (hence it not brightening up when my office lights are turned on I guess).

If I enable auto-brightness on mine, it seems to constantly vary the brightness in my office. It's annoying as crap and I turned it off. Am I the only one?

It's probably taking a look at the available APIs to see if it's easy to write a quick app to do auto brightness with settings to be able to tweak it.

The auto-brightness feature changes constantly for me as well.

I 'm also having issues of the varying brightness when using auto-brightness -- even though the lighting in my environment has not changed and I avoid contact with the light sensor. It's VERY annoying.
I've since switched to using a static setting for the brightness.

auto brightness was one of the first things i turned off. it was way too dim for me

Not bright enough for me. Doesnt seem to change much.

I do see the variability occasionally. Most of the time it's stable, but it will take spells of shifting up and down repeatedly. Glad to know I'm not alone.

Auto bright annoyed me as well when I first got the phone. Then I realized where the sensor is (top left) and what it was responding to. Depending on where I'm sitting, what light sources are behind me, in front of me but reflecting off of me. It's usually just responding to a light source that's just withing view of its sensor. Also, my hand has shielded the sensor more than just a few times, confusing the sensor.
Now I leave auto bright on all the time, and it more often than not does a good job.

IMHO this is one of the few broken features on the phone. In continuous lighting it jumps from bright to dim to everything in between like a jack rabbit on speed. I still use it to save battery life but it pisses me off regularly.

am also having this problem. it constantly goes much brighter, and then, suddenly goes back to dim.. very annoying... however, the light sensor for calling works well... so, is it a software issue.. hope it gets google's attention and gets fixed in next update...

+1 so I also manually go between three on the widget

Note that the light sensor is under the glass on the front of the phone. Some cover-all cases cover this, and if you use one of these I assume your phone will remain on the dimmest setting.
In general, while indoors it will remain on the dimmest setting (for me anyway), but rise to the necessary full brightness when in sunlight.

There are two sensors, one is a light sensor and the other is a proximity sensor to detect when you've taken the phone from your ear. I think you're referring to the second.

+1 constant occiliation on dimmness levles under consistant light. It goes from way too dim, to just right then back dark again. I too hope that google will correct this with the next update. Hopefully the patch gets pushed soon, i'd like that extra memory

Keyboard Light

Hi all,
I was wondering if there was a way to force the keyboard keys to stay lit up until you close it. It seems to be cutting out mid type.
Thanks.

It turns off when you it's bright enough in the surrounding area. You can flash cyanogenmod and set all the brightness settings.

Thanks,
I guess I was hoping to be able to control this manually without having to flash a different rom.

At this time its not possible to control it manually from stock froyo. Maybe in gingerbread?
Sent from my T-Mobile G2 running Cyanogenmod.

do you have it set to automatic brightness? I noticed my keyboard turning on and off while typing and the screen dimmed and brightened with it. Turned off the auto brightness and hasn't done it since.

Turning off the auto brightness hasn't made any difference to me on my DZ. The backlight for the keyboard and capacative buttons seems to turn off and on quite often for no apparent reason (badly calibrated light sensor ?).

has anyone tried covering up the light sensor with a sticker or something? lol idk

That would certainly work, you can put your finger over it and show how it's the light sensor doing it. Probably not the best long term solution though

Screen color changing? Negative effect?

Has anybody experienced any issue with their screen colors seemingly fading out to create what almost looks like a "negative" effect? It's like it gets very bright and washed out. It's fixed by turning off the screen and turning it back on, but I don't think I should have to do that. Anybody experience anything similar to this?

This I believe happens on Galaxy S5 Mini (I have it) where when it is set to Auto Brightness and I go outside under direct bright sunlight, the screen will boost brightness beyond the manual Maximum setting that you can set. In turn though, the colours on the screen will go psychedelic where things look very bright and washed out. When I go back inside, usually it stayed extremely bright, soI had to put it to sleep then wake it up again to put the psychedelic brightness back into sense.
On the Note 4, I tried this yesterday, colours didn't go crazy, it stayed pretty much spot on, but I still had to put it back to sleep and wake it to fix the brightness.
It's possible I wasn't patient enough to wait for it to return brightness back to normal after leaving direct sun light, but I did give it 10 seconds and it didn't go back.

I got the same experience with my note 4. At the beginning I thought that it was an issue with my screen. But it could be good to know if it is or not. If one day I will get a black broken screen... This issue appears only under the sun light.

Have you tried disabling the "Adjust screen tone" under display settings to see if it has any effect?

its brightness boost happens in bright environment if you close the auto brightness it will be gone. its not an issue. but gets too bright when not needed sometimes. but in direct sunlight where manuel max brightness not enough it helps alot and it doesnt look weird in a situtation like this.

AOD Dim after update

Hey i received an update for the Always On Display (update number 1.1.22)
after i updated the app i noticed that the AOD is much dimmer in some places than it was before
also i noticed that my girlfriend's s7 AOD is much brighter than mine in the same areas (they were the same before the update)
is there a way to undo the update? (was update through galaxy apps)
Thanks in advance

As far as I know, the AOD dimming is introduced in APD1 and later firmware updates. What is your firmware version ?

Yep, they pretty much ruined the entire feature. Its now too dim to see in anything but outside in full sunlight. Indoors its pretty much just a black screen now. Been a month, they still havent fixed it.

The update is to solve screen burning, this is why is dimmer now.
Cheers.

No, it never burned in since it was always moving. Now it is so dim that i cant even see it, rendering the entire feature useless.
It must be a bug, it cant possible be intended.

Dunno if you tried it but I noticed my AOD accomodates with the lighting condition in the room but im often sitting in the corner where I face the light so when I turn it off I face it to the light so the AOD would be bright. weird habit for now huh hahahah

Still annoys me to hell that they basically took one of the best features of the phone and essentially ruined it (so dark its unreadable indoors, if you dont have a ceiling light shining straight on the sensor). Just by a single little forced software update. Why couldnt they just provide a simple brightness slider in the AOD settings?
Third party AOD apps exist that allow complete brightness control, but sadly none of them run with the samsung AOD "tech" so they all keep the phone hot and running as if fully awake, draining battery more than just the pixels being lit do.

just done the update this morning and I didn't notice difference in the brightness of the AOD. it remained the same. are you sure your dim situation is not caused by some setting, which was reset after the update ? For example, It happened to the fingerprint lock setting in my phone, which become corrupted, unusable after the update. I need to delete the previously saved fingerprint and add a new one again for it to work.

100% certain it was the update. I literally can barely see the AOD indoors anymore. Before the update it was always very bright and vibrant.

How often does your clock move on your screen, because mine stays stationary unless I turn the screen on and it turn it off again, then it'll change to a different position.

Is this normal or problem? Brightness.

Good afternoon,
I do not know if it is something normal or it is a real problem that requires technical support. The case is that I have the mobile without automatic brightness, and when I set the brightness to very low levels, when unlocking the terminal, when you turn on the lock screen with the wallpapers, it appears as a slight flicker of the screen, thousandths of a second, almost imperceptible if you do not stare. Something like when you start to light a light bulb until you get to have light at all, but with a very slight flicker.
It is not an extreme flicker that completely turns off the screen or any of that, it may even be the operation of the brightness sensors (which happens to be strange because the automatic brightness is off), but I worry that it may have more problems in the future. Also I have noticed that having the brightness to the maximum of half of this problem does not occur, only with low brightness. There is also no blinking once unlocked using the phone itself, everything works perfectly. It is as if the lock screen was automatically adjusted when unlocked.
Should I contact technical support or just foolishness of mine?
Regards and thank you very much in advance.
PD: I have EMUI 4.0, NXT L29 with b192

Maybe you can upload a video so we know what ur talking about.

I think I've actually noticed something like what you're describing in my device. In summary, ever so slight flicker of brightness when display is on low/lowest level with automatic level off. I assumed it was normal

I have tried to record videos, but it is very difficult to appreciate.

I also think it's normal. It's like an automatic contrast adjustment to accommodate the eye to the screen. I think it's a matter of the IPS NEO screen.

Does anyone else have this?
