Hey everyone, just got a Galaxy Nexus and I am having problems with it. The screen brightness is always too dim to use, even after changing brightness settings. I don't believe it is a hardware problem as when I use the pull down bar or enter the main menu, the brightness is normal. On the internet app it seems as if there is absolutely no brightness at all (too the point where the phone looks like its almost off). On the home screen unless I use the specific background microbes there is no back-lighting.
Any solutions?
Edit: I was on 4.0.1 Yakjuux and now I'm on 4.0.4 Yakju - Not rooted and same problem on both.

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

He he good one
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

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.
Good evening (or rather, early early morning),
I have recently purchased a Galaxy Nexus and love it, except for one thing. When using the browser, or other apps with mostly white UI's, the screen dims by about 10-15%. I have auto brightness turned off, and the backlight set to about 80% (I like a pretty bright screen). When the browser launches, it is immediately dimmed. You can see the difference when using something like the search box on google.com. When the keyboard comes up, the screen returns to the proper brightness.
From reading threads on here and other forums, I know on phones like the Galaxy S3 have brightness controls in specific apps, like the browsers. For whatever reason, this isnt included in stock Android. I've seen other threads indicating this might be a feature that could be included in a custom ROM. Sooooo.... here's the TL;DR question:
Are there any custom ROMs currently out for the Nexus that have the option to disable this screen dimming?
Thanks!

PS - this is with Chrome, stock browser, Facebook, etc. Its not an issue with just one app.
It's a "feature" of Galaxy Nexus, and it happens on all roms . When you view a page mostly white brightness drops slightly, maybe to save battery
Trinity kernel has a setting called "Content Adaptive Brightness" that can be disabled.
good day.
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.

Saw the same thing when I launched camera app, I am on the latest update.
One difference is that I'm on auto bright and the brightness never came back

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."

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
I have a Galaxy S2 T989 that I have rooted and have been trying different roms. Yesterday I reflashed it back to T-mobile 4.1.2 and after I changed my battery and rebooted it got hung up. I did a hard restart and the screen display darkened a few shades. Now my display is not as bright as it used to be. Brightness is up as high as possible, auto brightness is off, and auto tone is off. What happened? What can I do?
Hi,
I've been a long time android user but first time to use android 4.3 (I still use 4.2.2 on my gnex). I'm confused by the display brightness slider behavior on my nexus 7 2nd gen. My normal understanding (from other versions of jelly bean i've used) is that if i slide the brightness all the way to the left, i get a dim screen (but still bright enough to see the screen, about 10% brightness), and sliding the slider all the way to the right results in max 100% brightness. I've noticed a different behavior with my nexus 7 2nd gen on android 4.3. Sliding the brightness to the left produces the correct behavior (dim screen), but sliding to the right doesn't increase the brightness, it just stays constant. In fact, sliding it all the way to the right leads to a COMPLETELY black screen. I find this annoying because I can accidentally make the screen dark and I can't see anything but the tablet is still running, and I can't adjust the screen brightness back to where I can see something. Is this an android 4.3 bug or feature?
