Apps can't control the Brightness - Nexus 7 Q&A, Help & Troubleshooting

I have an odd problem. Until recently apps could control the screen brightness. For example my video player has a brightness gesture so I can manually set the Brightness while watching a video. However now, no matter what I do, I can't control the Brightness via third party apps. I can use Android's built-in brightness settings and auto brightness mode but no other app can control it. I really want to get this fixed since a I'd like to try the Lux Auto-Brightness app.
Any idea why this is happening? I'm running Android 4.1.2 Stock with Root.

Automatic brightness adjustment?

Anyone know if there is a way to adjust the automatic brightness function - i.e. have it still be automatic, but be a little bright or darker for a given ambient light?
would really like to keep using it, but want my overall brightness turned down. using manual brightness with widget for now, but don't see why automatic brightness could not be tweaked. tried searching for an app to do this, but have not come up with anything. nothing came up in a google search of xda either. anyone got anything?
I want to know as well, I wouldn't mind setting the auto brightness to be more fine tuned as well, smaller changes.
Yes a better working app is needed. something like My Light or Lumos for winmo

Browser brightness

Hi
It seems that the browser has its own brightness setting. This causes the brightness to change when you open/close the browser, since it is usually not in sync with the general brightness. Is there any way to either disable browser brightness, or keep it in sync with the general brightness setting?
Thanks!

When using auto brightness, the browser follows that and disables its own brightness setting.
But I do not know what happens when you switch to manual brightness then.

[Q] Schedule an app to run and close per time?

I'm looking for a decent app scheduler that can run an app by a set timed schedule?
I'm looking to start this screen dimming app (super dimmer), by a set schedule, around 8pm and to turn off at 6am.
The app itself does have an internal scheduler, but it does not work correctly, but the app works exactly as I need.
So what do I need to do this?
What exactly am i trying to do?
Well, I like the auto dimming feature of my phone, however at night, I do not like the lowest default dimming setting, I am comfortable with a much lower dim setting that Super Dimmer can provide. I basically want it to activate at sun down and deactivate at sun rise.
I would be even more interested in adjusting the phones default dimming ratio, if that is possible, if I can control and lower the auto dim setting in phone, that is preferable.
Taskbomb task scheduler?

I did install taskbomb before writing this post, is that what I want to use? I just have no idea how to configure it.
Tasker is awesome. You shouldn't even need to use a secondary app with it.

Well looks like my idea did not work correctly. For some reason that program doesn't toggle on and off like I would need it to in order to work with taskbomber.
So this tasker app, does it allow for dimmer settings below the default android 0%? I'm looking for 200 levels.

I havent tried to myself, but it does have ability to ask for SU and device admin permissions so I bet it does.
I got it, tried it, it does allow for you to set lower than default values for some devices but for some reason it doesnt go as low as super dimmer did.......
Hmm I'm all out of ideas now!

Adjust auto brightness

Is there anyway to adjust the brightness level of the auto brightness?
My problem is as follows: to save energy I usually set the brightness to the lowest level. If I want to use the tablet outside literally can't see anything because of that and have to go inside to adjust it. If I use auto brightness the brightness is to high though for most purposes. My ideal would be to use the brightness level the automatic mode sets minus 10% for example.

Great Idea! I would really luike that one too. I'm pretty shure that the option doesn't exist in standard roms. But maybe an app?
I thought about looking for apps a couple of minutes after I started this thread and was kind of embarrassed. However, I didn't find any that worked the way I want them to.
I stumbled over one here in the forum lux something, but I doesn't work with jelly bean I guess.
If you find one, please let me know

Lux auto brightness does exactly what I want. You can set up different screen brightness settings for different lux values. It's an awesome app, check it out

Brightness level

Is there any way to decrease the brightness level without root? I have been using apps but they don't dim the notification bar and volume controls.
Try YAAB aka Yet Another Auto Brightness from play store, you can set minimum or maximum brightness manually.

Tried it still no use the brightness level is not affecting the notification/pull down area and volume also.
It a limitation with latest android versions... I am afraid there is no fix to it... All screen dimming and filter apps seem to have the same problem..
