[Q] Third party screen brightness control not working - Samsung Galaxy Nexus

I have a problem that I can't really figure out, so I hope you guys can help me out.
I have a Galaxy Nexus which I'm very happy with (GSM btw). I had one problem though and that was that I didn't like the auto-brightness. The brightness was often too low so I searched for an alternative. I found one in Lux and it worked great.
Lux is a brightness control app and you can basically customize your auto brightness to your liking.
After a while though it stopped working and I now I can't change the brightness with lux anymore. It doesn't matter if I set lux to 30% or 100%, the brightness stays the same. I do suspect that the brightness it does stay is the brightness currently set in the system settings.
After this problem I started test other apps that can control brightness and I noticed the same problem. I still can't control my brightness.
I do have to say though, there are a few occasions where I actually can change the brightness, but those moments are totally random and are that rare that the app is still unusable.
Oh and one more thing; Lux has a feature called 'sub-zero' where the app sets the brightness even lower than is possible with the system settings and that feature does always work.
Anyone have an idea what the problem could be or how I can figure out what the problem is? I think one possibility is another 3rd party app interfering with the brightness, but I can't figure out what app. Is there any way to easily check all the apps that use the 'brightness change' permissions?
Edit: I'm stock running Android 4.0.4 and not rooted.

Are you stock?

If you mean it's the problem of the app, then no, it's probably not, because other third party apps have the exact same issues.
If you mean it's the problem of ONE of my apps, then yes, it's possible, but I have no idea how to figure out which app. I don't want to do a factory reset, neither do I want to uninstall and install every app I have just to see if it makes any difference (I have more than hundred apps).
If you meant the latter; do you know any way to check out which app could cause these issues? Maybe another app which shows me all apps that uses the brightness control permissions?

Do you feel it really increases battery time?
I am currently trying out Juice Defender free on the standard preset for my unmodded Galaxy Nexus. Unfortunately I am not thinking that I am going to continue with it.
So far it has crashed my phone to reboot (first time that has happened) and when not using my 4g it turns it off but it takes forever for it to come back on once I want to use the phone and it gets pretty frustrating having a useless phone for about 5-8 minutes everytime I pick it up.
I hope you have better luck than I am having.

Strange. It's never done any of that on mine. I'm on HSPDA+ though.
As for whether if makes a difference I'd definitely have to say a big yes. But it all depends on how you use your phone.
Ultimate working nicely here. Syncs every 15 min like it should. Screen is eating 60-70% so it makes only a small difference.

I bought ultimate, and found it to be a bit of a hog. I then turned off all the extra stuff and went back to the basic setting - the same as the free version, and noticed very little difference.
I think it might help you if you're one of those people who accidentally leaves radios on, or don't have high signal most places you go. For me a UV kernel made the only real difference.
It works well but not saving as much battery as it did on Gingerbread. Default Android idle-time battery management seems to have got much better.

This. I see a nice increase in battery life while I'm not using it, but if I have it on a lot (which I usually do) the battery gets drained pretty quickly.
I keep my phone on CDMA mode most of the time, unless I need to download something or want to watch a movie, then I switch to CDMA/LTE. I'm still not sure how much it helps though, as I've only had the phone for a little over a week.
For me, JD Ultimate works wonders. Especially when I'm at work and not playing with the phone too often and having only 2 signal bars, JD enables radio every 30 mins to allow apps to sync. It also manages my brightness automatically, which results in screen usually taking less than 50% of battery.
In general it helps me a lot, like it did on SGS2. My night schedule uses airplane mode and I only loose 2-3% over night.
I would have to remember about too many things if not using JD, so for me well worth it.

I thought brightness worked only in the beta version. Does it work in the release now?

It does, i never used beta and JD controls my brightness. Remember there is a bug related to manual apk install where you cant tap install. I still use JD for brightness, just disable it in quick menu when manually installing apps then reenabling right away.

Thank you for your answer.
When JD is managining brightness, if the phone is asleep, when waking it up with the power button the screen comes full brightness and then settles to a lower level, which is quite annoying. Do you see this happening too?

That is totally weird, cause mine seems to wake up high and only then lower the brightness. I wonder if it's ROM related, although I'm on stock kernel 4.0.3.

Make sure system brightness is set to Auto. And I use Filter Mode in JD. Sensor is set to Normal.

Beacuse, believe it or not, it provides functions that some people find useful. Same goes for LightFlow, if you like the white-only color led notification of pure android, then you don't need this app either. If you prefer more colors/choices, then you do.

I purchased JD Ultimate yesterday so I can't really comment on how well it is improving my battery life. I will say that I am having issues going back to LTE when the screen is unlocked (Using the network mode setting). The phone keeps going to WCDMA instead of LTE. However, I noticed that since I have been using JD Beta 3.8.8, version 3.8.9 has come out and has addressed a few of my issues. The configure apps now works without crashing JD. I still don't know if the LTE is functioning incorrectly as I haven't had time away from my computer (I have no Wi-Fi at my hotel and must tether).
Is anyone else experiencing issues with the phone going to WCDMA mode after the phone wakes up? Also, what version of JD are you using?

Autobrightness bug

Hello little birdies.
I am having an issue with my auto-brightness and I would like to know if anyone else has experienced this.
Whenever my auto-brightness shines through the power of the sun (goes to 100%) it seems to get stuck at full brightness and my already not so good screen-on time takes a dip and I always notice this too late . I use the quick settings widget which is preinstalled and the A for auto-brightness is set but when I click it the screen immediately lowers the brightness, while the A for auto-brightness remains, and a vain in my forehead pops.
Furthermore after checking badass battery monitor it shows that my screen is often at 100% sun shadowing brightness. Today it was at full mutated power the whole time. Anyone got an idea as to what could cause this? Anyone?
PS. You might have noticed in the text above that I think the screen is really bright when at full power and that I can see the screen perfectly during a warm ball-soothing sunny day.
Yes, I have a bug with auto brightness too. It seems to deactivate itself. I have activated it a couple of times and everytime it deactivate itself at 100 % after some use.
I have an international HTC One X with the latest 1.29.401.11 update.
Glad to know I'm not the only one. I will soon factory reset my phone to check if it magically gets better.
I noticed this last night. My phone was blindingly bright and I didn't understand why it was set to 100%. I set it back to Auto and so far its still on Auto. i will have to keep an eye on this.
HTC really need to fire the monkeys they have working as coders. I guess if their software is not fixed up in next couple of weeks there might be a whole lot of people, me included, who will migrate to the SIII (given of course that it doesn't have a gazillion bugs as well).
I've been trying all day to recreate the problem but ist not doing it. I put my phone in the sun, I tried using the camera app, I used the video app with its 100% brightness setting, but the phone is still showing Auto brightness.
Any ideas on what triggers 100% brightness?
I have the same problem with mine. It's just randomly turns off auto brightness
Sent from my HTC One X using xda premium
I don't know either what triggers it. It seems to deactivate at either 0 % or 100 %.
I don't have many apps installed, if I just do some web surfing and put it to sleep, when I wake it up the auto brightness is deactivated, in maybe 1 of 4 times. Irritating.
For whatever reason i haven't been getting the auto brightness bug for the past three days. Not sure how it resolved itself since I didn't get any software updates.
If you watch a video you can change the brightness and will stick and not go back to your original settings.

No, that's not the trigger. I investigated that on my phone and found no link.
I take that back. You are right! It seems the brightness setting in the movie play is the culprit. Although it doesn't always do it. One more thing for the chimps at HTC to fix.

Yesterday the auto brightness bug kicked in right before my eyes. I was browsing the web in total darkness in bed, when suddenly I was blinded by 100% brightness. So it's not just the movie player brightness that causes this issue.

Yeah. That's because the camera jacks up brightness for outdoor visibility. They need to have an option to disable that.

I realize that, however it doesn't always do it. Also sometimes it will kick into 100% brightness without using the camera or movie player. It seems completely random to me.
mine is stuck at zero. started this morning and I did record a video actually.
auto just takes it.to zero.
but also, if i change it directly from the srttings menu, its not.effecting at all, just staying at the same previous custom level.
whrn using widget, just turns it to zero.
opened the video player, changed brightness level and its normal now. it was in the middle, the video brightness level
ok just edited this post and its malfunctioning again.. arrrgh!
Try an application that controls autobrightness, it should fix the problem. I would recommend Lux Dash.
So it is the widget, powertoggle.
Once I fix the issue by changing video brightness, it works fone, till I toggle the widget to use auto-brightness.
Several comments on PlayStore also confirms this with several phones.
Just don't use auto brightness from powertoggle. It is actually doffetent.from what OP describes, but.people may come up to this thread while searching, so I think it willbe useful to post here.

Preventing screen dimming while charging?

This is a big problem when driving and using GPS. The device is plugged in but then dims after a minute or so, making it nearly impossible to see in daylight.
What can I do to prevent it from ever dimming while charging?
Settings>screen dimming
Turn it off

There is this OLD free app I have been using for a long time. SIMPLE and EFFECTIVE.
It's a Screen On Widget. When you want the screen to stay on, simply click either a SHORTCUT or a WIDGET. You can disable from the notification bar as well. It's a manual solution. There are other automatic solutions, but they will cause some battery drain and mild cpu. It's hard to find. I uploaded it here.

This option is removed in TouchWiz, its an AOSP option. However, this is one if the first things I've re-added to TouchWiz. OP, if you can survive until Monday, I'll post up a flash able package to re-enable this option.
Sent from my Samsung Galaxy S III
As promised, here's a CWM flashable package that will re-enable the "Stay Awake" option in Settings > Development.
This is for the SGH-I747, UCALH1. This package is for a stock, deodexed ROM, so if you're running an odexed ROM you'll want to delete your /system/app/SecSettings.odex file after flashing.
Enjoy!
as a precaution just remember that Samsung removed the option to prevent burn-in to the amoled screens, something that was a big problem on the epic 4g. also to reduce wear on the leds.

Jellybean Auto Brightness

So this is the issue I'm having and I want to know if its just me or what. On stock jellybean for the Sprint Gnex. When using auto brightness and going into a bright lit room the screen brightness will raise. But when you leave the room it will not lower the screen brightness. It sticks at whatever brightness level is raised too until you lock the screen and then it resets. I have verified the light sensor is reading the lux levels and such. Is this happening on other people phones as well? And if so is there any known fixes for it.

This is happening to me as well. I am running Paranoid Android 2.0 at the moment. I was in bed, completely dark room, and turned the brightness to auto. It stayed at the full brightness setting until i locked and unlocked again.

Did it work properly after that or will it still not dim when leaving a bright room until you lock and unlock.
I have tried holding my finger over the sensor for like a minute and it still wouldn't lower. I'm trying to find a reasonable fix for it. I've read adjusting the levels in the framework apk will fix it but I haven't gotten that to work yet.
Crazy part is. If you use an app to make your own custom levels it starts working. Same thing with cm10 if you use the built in options to set custom levels. But for whatever reason is doesn't want to work on stock for me.

OK. So this is wild and awesome at the same time. I flashes the newest version of rujellin last night. I left auto brightness enabled over night. Woke up today and its working. How crazy is that. As soon as I disabled and enabled it to see if it took. Stopped working again. It has to be in the phone or the code one. When I say code I mean Google code.

I haven't used stock JB, but CM10's auto brightness is great, especially all the advanced settings
It seems to be slowly starting to work. Its crazy. Makes me wonder if some info is getting left behind when I do a full restore to stock. Thanks for the info. I just want to know its not just me.
Sent from my Galaxy Nexus using Tapatalk 2
Edit. I was wrong. It wasn't working that was the screen dimming before it locked. After a some reading and searching xda it seems that this is the default behavior for the auto brightness feature on android. I'm not sure if this is correct or not but the ammount of people saying that versus saying otherwise is greater so Im going to have to agree.

Automatically disable data during the night on cm10?

Hi,
As I am losing 20% overnight (which means no alarm clock in the morning) I need something to save my battery.
Maybe it is possible?
I would like an app which turns off:
- wifi
- Data
- Changes to 2g
Maybe something else?
Thanks!
Sent from my Galaxy Nexus
Just manually turn off data before you go to bed?
Or plug the phone in...
Or... buy an alarm clock? There's an idea .
I believe CM10 has this setting under "Night Mode". Try searching in your settings for that. I would give you a more specific answer, but right now I'm not running CM10, but a lot of other roms have this option. It allows you to set the times and apply certain data and toggle settings. Then again, I could be completely off and CM10 might not have this.
I know Airplane mode would disable all carrier connections, but that still leaves WiFi. For that, could you not simply disable WiFi itself?
Go into profile and edit the night profile and you'll be set

You can look into using an app called Tasker. It has a vast array of useful tasks that can be automated.
There's an app called LLAMA, which should work.

Not sure if it is a best solution and what are the alternatives. But I love Llama now.
I confgured 4 events (home, home night, work, outside work or home) and testing them.
Switching between events is a bit laggy but seems to work.

Even with data etc on, the phone certainly shouldn't eat that much battery over night. Find what's the true cause (poor app) instead.

personally i use an app called Green Power that you can set times and modes for that disables data when the screens been off long enough and a number of other useful features to help with battery life.
