Has anyone noticed that their auto brightness is kind of broken after upgrading to JB? For example, if I'm in a really bright area and go into dark, the screen does not dim itself, however this can be fixed by going into settings and un-checking and checking the auto brightness box.
Obviously this is pretty annoying... Is there a fix for this?

I've noticed the same. It stays bright a lot of the time in dark places. I haven't noticed it staying dim in sunlight though.
To me, the way it was before seemed broken. It would constantly change its brightness level. This was effected by the light reflected off clothing, etc
I love it now

But I Dont find any issue with it either. In fact, if you dig in, you'll find the process consumes 30% lesser battery than before ie. Screen + sensor timing and refresh for both...

I'm actually pretty sure this is the default behaviour for ICS as well its only 3rd party roms that added in the ability to auto dim as well as auto bright the stock way is it only goes dimmer if the screen turns off and back on other wise it stays at the maximum brightness
Sometimes if I'm using the widget to move from full to auto brightness and tap very fast, it'll sit at full brightness. If I toggle slower its fine. Definitely some bug there.
I think auto brightness is much better in 4.1.1. Before it was far too dim, now it seems just right in all conditions.
I'm using the app "Lux Auto Brightness" and it couldn't be doing a better job.
Definitely check it out if you're unhappy like I was with the stock auto-brightness
Sent from my Galaxy Nexus using xda premium
that has been the default behaviour from ages for stock goole rom:
the autobrightness only can increase...it doesn't decrease, unless u lock and ulock the phone or check and uncheck autobrightness
that the intended behaviour google want..the brightness get increased, but not decrease..
So you're saying that the auto feature in 4.0.4 was broken then?

Yes, it delayed the lock screen and when I set my phone down under a bright lamp and it woke up hours later in pure darkness, it might soft reset.
happens to me as well on stock 4.1.1. if I'm in a dark room and put the phone under a lamp or something, the brightness goes up instantly, but it never comes down until I lock/unlock the screen again.
in fact most of the time I think the thing is too bright (but that may be because I come from a nexus one always on the lowest setting since the autobrightness there didnt really work well).
it's a minor annoyance definitely
Same Problem with Note2!
Hi guys,
found this thread during my search for this brightness issue. My Galaxy Note 2 has the same strange behavior. But I figured out something: when I lay down the device to a table or bring it to 0 degrees in my hand, automatic brightness it's decreasing perfectly! Can you confirm this behaviour at your nexus? I guess it's a kind of strange Samsung " feature", maybe?
Thanks, Michael
Ahoy, I was also researching my auto brightness issues when I found this thread. I can confirm the behavior from the previous post on my SGS2 on Jelly Bean 4.1.2.
If the phone is in vertical position and I do the lamp test, it will stay on maximum brightness no matter what, but in horizontal position dimming works perfectly.
Regards,
zytrel.
With auto-brightness turned off and brightness turned up all the way, I am seeing the brightness go down when some apps are launched and turn back up when the app is closed. I noticed this today when launching GoChat and then also saw it when launching the stock jellybean web browser. I am not sure but I think this has only been happening since the last software update (T-Mobile USA).
I wonder if others are noticing this.

From DisplayMate:
Since the display often uses 50 percent or more of the total Smartphone power, various display power management schemes are frequently used. The Galaxy S4 uses one innovative approach to overcome this – when Automatic Brightness is turned on, the Peak Brightness becomes significantly brighter in high ambient lighting than is possible with Manual Brightness, up to as high as 475 cd/m2, which is 34 percent higher than is possible with Manual Brightness. This is done so that users can’t permanently set the brightness to very high values, which would run down the battery quickly.From Samsung:
Samsung Adapt Display: The Galaxy S4 "learns" what you are viewing and adjusts the display's brightness accordingly. If the phone senses you are reading an article, for example, it will illuminate from a more muted brightness.

Well, I have auto-brightness, auto adjust screen tone and power saver ALL TURNED OFF, but this 'feature' persists... and as I said, this is not just during web browsing, this is also during messaging with a 3rd party app, namely GoChat, with black background theme.... this is just not a smart feature.
maybe this is taken care of in the new update. i haven't unpacked it just yet. hoping to do that over the weekend or maybe even tonight.

What you're describing sounds like how Adapt Display is supposed to work. Does the display act any differently when you enable Adapt Display?

I have the same issue. Turned everything off completely and it still happens. I posted about a week ago and some people were having the same issue.
Some people said it was adapt display on, but I have it off. Once I switched to.the CM10.1 the issue went away. I switched back to wicked Rom and I'm still getting the same problem.
Maybe a dev will eventually figure it out while building a Rom

It seems like this is a feature that cannot be disabled by the end user. This is from Anandtech's review
"On the brightness front, the SGS4 includes dynamic contrast functions that cannot be disabled and change as a function of what is being displayed. There's an "auto adjust screen tone" checkbox under display but don't let that fool you, that doesn't disable dynamic contrast, just white point."
http://www.anandtech.com/show/6914/samsung-galaxy-s-4-review/8
If it really annoys you, you can always try rooting it and install CM10. I'll be a drastic change but at least you wont have to deal with Samsung's bloat
Well the autobrightness wasn't working as I wanted it to. Never had issues with it before on other devices.
So I downloaded Velis auto brightness
I noticed the sharp brightness sensor was sometimes juming between 2 values like 552 lux and 12 lux causing a constant change off brightness. (flikkering)
Could someone check the brightness sensor, and check if it also fluctuate? My S3 keeps steady values...
I had a faulty pro8.4 (dead pixels) on the first day and the auto focus was also not working properly.So I would like to know wheter I have an other faulty tablet or it is just the sensor that reacts differently.
thanks in advance
I have noticed the same thing. When I am scrolling through a website I notice the flickering brightness. I ended up turning the auto brightness off.
My auto brightness just doesn't seem to work at all. It just defaults to lowest brightness. Funny thing is it worked on first boot, but stopped after the very first time I turned the screen off then back on.

I installed CM today and using auto brightness, I can confirm it just goes up and down, dim-bright-dim-bright. It's disappointing that such a nice tablet has a piss-poor brightness sensor.
From my Pro Tab 8.4
My Lux values were all over the place too. Luckily there's an application on the Play Store called Lux which fixes everything. Just set it to adaptive. That's what worked for me.

Can you go to Settings >> Display >> Brightness and then click the settings icon and then the Adjust button. That should tell you the value of the sensor as seen by CM.
Does it really fluctuate there? If so, can you maybe take a quick video so I can see what you are seeing?
I'm pretty sure this is a hardware issue. My sensor flips +/-1 when I leave the tablet sitting there. Covering the sensor drops in down to about 0 and then it bounces right back to the same value when I uncover the sensor.

Wow Thanks so much for suggesting the Lux app. The stock auto brightness jitter was driving me crazy, especially when scrolling around in the playstore.
On a side note, samsung screens are hella bright when viewing at night. Going to put Lux on my phone too lol.
A autobrightness mod I use on my Nexus 10 is the XPosed framework and Gravity box module. Your can set the brightness and lux pair values then reboot. On my Nexus 10 it took three days (night/day) conditions of tuning values until I found the sweet spot. It was not too much of a bother and I've not had to make any adjustments since. Look in Gravity box for display tweaks then all settings can be modified but the pair values mentioned above are under autobrightness levels.

With most Android Wear watches lacking an ambient light sensor, this Huawei one included, I'm wondering if you often have to manually adjust brightness, either not to be blinded at night, or to actually see the screen in daylight.
As far as I understand, an awake watch will get brighter, and ambient mode will be darker. There's also the double and triple crown clicks for theater (screen off) and sunlight (brighter) modes. And things like Display Brightness for Wear, or through AutoWear for finer grained and somewhat automated results.
And that's what I'm really wondering: if I can get a satisfying custom behaviour through AutoWear, by slices of day time (eg, brightest at noon, and progressively darker as night approaches), that'd be fine enough to me. But if I constantly have to adjust things manually, I fear that would quickly become annoying (I can spend a lot of energy tweaking automation to ensure I can be as lazy as can be afterwards ).
Do you choose a middle ground brightness setting and are fine with it most of the time, except when you rarely have to double or triple crown click? Do you find yourself manually adjusting brightness a few times a day? Do you constantly fiddle with brightness settings?
I don't touch it at all. I have it set to 4 and could even get away with 3 if I want. When you need a brightness boost just hit the crown three times and you're set.
I missed it greatly from my urbane, so I went back to it.

Crown
So, by hitting the crown three times, the brightness goes up one level?
Also, is the crown button function behavior customizable?
Thanks!

Have the watch since tuesday ("Active", ie black, with single layer leather) And I agree: most of the time, 2 or 3 are enough. 1 is actually even too bright to me at night, especially since I'm seemingly unable to have ambient brightness get as low as how bright it is awake at 1 (is ambient brightness level fixed?).
Under direct sunlight, it's not always that easy to see even with the bright 3-click sunlight mode. But generally, twisting my wrist a little to avoid direct reflections, or at worst covering it a bit with my other hand, is enough.

Ambient mode brightness is not configurable on the watch, but certain 3rd-party watchfaces offer this setting. I'm using Skymaster and it offers different brightness for ambient mode.

Does that setting only apply to the actual watch face, or to the whole display? I've managed to make it dimmer with a partially transparent black layer in WatchMaker, but it doesn't apply to cards previews, or icons such as mute...
SWapp True Dark allows for actually adjusting the brightness of the whole ambient display, which is already great, but I'd rather have that manageable through Tasker (to have it auto adjust by time of the day). Have asked João if this could be implemented in AutoWear, so maybe it'll end up manageable through that.
Seems quite crazy to me this setting is not available by default. Reminds me, even though I think Android is the best OS of its kind, how lame I find it without the truckload of customization I lay over it...
I have 8 days ago my Huawei SW. It's my first SmartWatch and I'm really disappointed not to do anything with Tasker and Android Wear to adjust brightness to my liking clock automatically.
On the day I need more brightness when I'm out and at night the minimum brightness of the screen saver is very strong.
The bothers me most at the moment is so intense brightness of screen saver at night. No achievement make it more tenuous. Anyone know if there is any app that you can do?
Hopefully one of the experts and boys of this site something to be developed further manipulate Androi tasker and wear.
I've been using Display Brightness for Wear. It allows for different brightness settings for day and night in different situations. I wish it was more customizable or there were some ways to control brightness with tasker. Unfortunately, I've been unable to find those.
Autowear just needs to be able to receive a message that ambient is selected. It thinks the watch is off instead of in ambient. Frankly, though, SWapp does what I need. I also use WatchMaker faces and customize the dim mode to my liking.
i use Wear Mini Launcher and have it set to show the widgets before the apps, so one swipe to the right gets me a brightness slider. Its very each to adjust this way. With Wear Mini Launcher I can also quickly set my phone to silent/vibrate mode, turn on flashlight, ping the phone even if the phone is on vibrate, etc

I've thought of something somewhat cool but I'm no developer.
What if we can use our cellphone's ambient light sensor to sync with the watch so that the watch can get both bright and/or dim when needed?
Theoretically this will function correctly if your phone isn't in your pocket all the time.

If you're as annoyed as I am by the fact that the minimal auto-brightness level is set even in fairly bright rooms and you would like to adjust it, then I have a simple tool for you. Just start it, enter your desired adjustment level (0-255) and click OK. My app will set the brightness immediately, and also every time the screen turns on (this is required because the adjustment does not seem to stick for very long).

It shouldn't have any effect on battery life. It shows 0% used on my phone in the last 48h.
Hey... Thanks for your app. It's definitely working. I'm not 100% sure what it does though... Does it set the lowest possible autobrightness level, and then the automatic adjustment takes over from there? Can you explain a bit more?

Let's say the auto brightness sets a brightness level "x" normally. If you adjust the auto brightness in my tool then the brightness will be set to "x + whatever you put in my tool" instead.

So, then something funny is going on. At the moment, it's full sunshine out and using your app is making the screen dimmer. I've set the app to '50', and when I turn the phone on, the screen dims and I have to toggle autobrightness off and on again to reset it to full brightness. I'm not sure whether I'm using it wrong, or it's a bug?

Edit... Further observations:
When conditions would mean full brightness on autobrightness, it feels like the screen is SUBTRACTING the amount I put into the app. Does that make sense?
Not sure what's causing it for you, it's working fine on my phone. Sometimes it gets bugged and it goes from full brightness to zero again, but that's because the setting does not seem to stick for very long, I just have to lock and unlock the phone and it works fine. It shouldn't be subtracting from the brightness though.

I've posted an update. I noticed the brightness adjustment resets very often so I've added a functionality to set the adjustment every 2 seconds while the screen is on. It shouldn't have any effect on the battery as it barely uses any CPU (less than 20 second in the course of a whole day).

Works fine except when you want the maximum brightness, for me it won't let me use max brightness unless there's much light and it activates itself
In the changelog for 4.5.11 is says they improved autobrightness. Has any of you noticed this? Do you still need this mod, or do you just need the update...?
In the 4.5.11 seems works a lot better than before, but still far froms iOS perfection, anyway give it a try!
Tried it on OOS5. It stops working afther I change the brightness manually. Brighness goes to 0 afther unlock.
Good Solution
Thanks for providing this minimal app, I just discovered it & it works great. Better than Lux Lite shall I say (my previous solution)
Does this work with Android in general or is it just for the OnePlus?
I have the same problem with a user in a previous post.
It does work as the minimum brightness according to the value I set, but also limits the maximum brightness.
For some reason I never get it.
Only if I set 255 in the app.
