[IDEA] Brightness Control for AUTO Brightness - Nexus One Android Development

I figured this would come along by now but for some reason it hasn't. On my iPhone I could set my brightness that the auto brightness would adjust accordingly. Because the auto brightness is generally too bright or too dark. Also maybe adding some timing controls for how long before the auto brightness adjusts. The displays in these devices suck down the battery like crazy this would help significantly.

I too thought we might have seen this by now. I know there have been some tweaks in ROMs, but a slider that sets the sensitivity or the upper/lower limits would be excellent.

Extended controls has an Auto Brightness setting, same as Froyo Power Control widget.
What OP wants is auto setting where you can control sensitivity of light sensor.

Ok I'll try explaining again. Communication isn't my strong suite. Basically, on an iPhone you can set auto brightness, then under auto brightness checkbox you have a slider that calibrates the brightness throughout the range of the ambient light sensor. So it's still a brightness control it just works in conjunction with the auto brightness setting. Being able to fine tune the brightness throughout the range of the ambient light sensor would be a bonus because with the current auto brightness I can barely see the screen in daylight but it's not maxed out because I can still adjust it all the way up with the power control widget and the opposite is true at night, i could go dimmer at night and still see the screen clearly. Strictly copying the functionality of the iPhone wouldn't fully address this. An app would be ok I suppose but I'd much rather see a system mod. I really hate apps like Trackball alert, nothing against the author I just don't like running an additional app to address the lack of a feature in the OS itself.

Good thought
I agree completely. I'm a recovering iPhone user and the adjustable auto-brightness is a feature that I desperately miss. One of my top complaints about android.

This idea is fantastic. It's something I've been thinking about too (never knew iPhone has it though)
When indoors I sometimes find auto brightness too bright. When outdoors and its sunny sometimes its upper limit is not bright enough. In both situations I have to turn off auto.
Actually last night I noticed that auto brightness was dimmer than the lowest brightness setting. I reckon that a lower/dimmer threshold should be available too on the manual brightness settings.

[Q] No Auto-Brightness Setting in 2.1?!

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?!

Auto screen brightness -- too dim in dark environment

It works, it's just that it over compensates in the dark.
I know there is probably not much that can be done about it, just thought I'd ask.
I think the Auto brightness is adjustable.
I agree it gets too dim, but works fine in normal lighting conditions.
The brightness is adjustable, manually. I have not found any means of adjusting the bounds of the auto brightness mode. It is the low intensity limit that needs adjustment.
I would like to be able to have a feature like adaptive brightness like what's on pure Android without a third party app...

While on auto brightness tap the sun burst directly opposite the checked auto brightness. Voila!
0-50-90
But then the whole phone goes dim. We want the brightness of the 2nd screen to stay bright at all times so we can see it.

Awesome! Didnt know about that feature!
I find the auto brightness is a little too dim. I would prefer if it was 10-15 points brighter than what the algorithm chooses. Now I leave auto brightness off in most cases of active use

What happened to Auto Brightness with the Marshmallow update

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.

The screen is way too bright and there's no way to adjust it when outdoors

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.

auto brightness too low

Since I got the a21 I noticed that when I'm out with auto brightness on it adapt to the sun but once I'm home the brightness slider goes all the way down
and pretty much stay there unless I go near a light.
Is there a way to recalibrate the auto brightness?
