You know I've always wondered the same thing. . from the looks of it it seems as if it simply adds an overlay to the screen.
I have tried it and use it at night sometimes so my screen doesn't hurt my eyes, but the screen looks as if you simply put a film on top of it, and it seems as if the actual brightness isn't effected underneath that layer.
Which in the end I've never fully understood weather it saves battery or if it wastes more battery considering the screen is just as bright underneath with an overlay on top.
I'm sure i'm wrong here, but dev will shed some light on it

This is definitely not just an overlay. It does controll the backlight of your phone down to 0%. Below that it must use an overlay because the backlight of the screen can't be set lower than 0%. Therefore going into subzero doesn't save battery. It only saves your eyes in the dark.
I'm not the dev, but pretty sure it does work like that.
Great tool by the way

Can you adjust the intensity of that red overlay thingy? It would look better if it were a bit less intense

You mean night mode? Click the Nighttime "Manual" button on the right hand side and you are given a slider you can toggle.

No, I mean the Astronomer Mode. I can't find a slider which configures that option.
Lux not working
Just purchased the paid version to support the developer but I've noticed that it stopped working all of a sudden and I'm not sure if it's a bug or it's something to do with the way I have configured it.
It was working fine yesterday then when I got up this morning the app no longer refreshes the lx value... even when opening and closing the app from the app drawer it used to auto refresh the value but this morning it seemed to be stuck on 1lx no matter what I did.
I fixed it by going into settings->advanced and ticked off/on 'Enable Lux' and it's now working again. Am I doing something wrong or is this a bug?
I'm on a Nexus 5 with 4.4.

Sounds like you had simply turned it off somehow.. Should be good now

I'm getting the 'Update for "..." could not be downloaded due to an error. (403)'
I don't think this is being caused by the new update but this is the only app I'm receiving this on and never saw it before trying to download it. Has anyone else seen this?

Both. First the backlight, and when that's at minimum, it adds an overlay.
See above reply.
This isn't adjustable yet.
The low pass filter dampens rapid fluctuation of lx values. With the decay option the lx value will gradually become the latest reading if enough time has passed with no readings.
Have you tried clearing the Play Store app cache?
I sure have. Thanks for the suggestion though. I've tried just about everything I've seen through searching the internet. It kinda has me stumped that its just happening with this app. I've even tried uninstalling and re-installing Lux by using the Playstore web page.
By the way, this is the best brightness App on the market, IMHO. Awesome options and flexibility of configuration. It just plain works!
May I have another feature request? Would you please add android activity/shortcut to change profile (day to night, car etc.)? Combining it with launcher gesture (most of the custom launchers have it) will allow quickly and easily switch between profiles without need to enter the app.
Would that be possible?

Thanks. So this is basically a sophisticated version of the "jitter control" option in the Brightness settings? Should I disable jitter control if the low pass filter is enabled?

Despite the recent update that was supposed to fix some flicker issue, my screen still occasionally flickers, especially when turning the device on. This only happens when the Nexus 4 screen plug-in is enabled. Is this just something I have to live with or are there any changes I can make to the settings to fix this? Thanks.
Update: I have 2 google accounts on my phone. 1 of them seems to be the offender. If I remove it, the other one will add and remove Lux with no errors. As soon as I add the offending account back, the 403 error returns. I've tried using the web play store interface and get an error there also if I try to do an install.

App Description
Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If, for example, you step into a dimly lit room, Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.
Lux provides the option to automatically adjust the backlight at fixed intervals (periodic mode), when a change in environment is detected (dynamic mode), or when the phone wakes from sleep. It's also possible to adjust the backlight manually. Simply disable automatic mode and you can use it like a traditional brightness tool!
Perhaps the best thing about Lux is that you can teach it how to behave. If the backlight is too bright or dim for your liking, simply open the provided Dashboard, adjust the brightness slider to the level you desire, then hold the link button. Lux will use this new 'link' as a reference in future.
Give it a go! I want you to test Lux for more than the 15 minute refund period offered by Google. I understand that some devices may not have the best quality light sensor, and that you may need more time to play around with settings. If you find that Lux doesn't suit you after the 15 minutes is up, you can request a refund at any time via e-mail - no questions asked.

Soon Lux will support plug-ins to bypass Android API limitations. These plug-ins serve to replace the overlay system Lux uses to make adjustments for Night/Astronomer modes and brightness in general. The plug-in library is free to use for non-commercial development, and can be found here:
Lux Plug-in Library | Nexus 4 Sample Plug-in Code
How to make a plug-in
There are two approaches to making a plug-in for Lux. The passive and the active method. The former is as easy as providing a set of superuser commands for Lux to interpret and apply. These command correlate to functions such as setting pixel RGB or brightness levels. This is the type of plug-in the Nexus 4 sample linked above takes.
The active method requires you produce your own code to perform RGB/brightness adjustments. This might include importing a device specific library to do the heavy lifting, and then returning empty superuser commands back to Lux.
Getting Started
Simply import the Lux Plug-in Library source into your IDE as an Android Library Project, and then create a new Android app which extends PassiveDisplay.java.
PassiveDisplay provides hooks into Lux's plug-in framework, which you can use to provide superuser commands for Lux to execute. These commands correlate to functions such as setting RGB values. Take a look at the sample Nexus 4 project to see how it's all done.
Finally, in your new project's AndroidManifest.xml file, add the following:
Code:<activity android:name="com.vitocassisi.lux.plugin.MainActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name="com.vitocassisi.lux.plugin.LuxBroadcastReceiver" android:exported="true" > <intent-filter> <action android:name="com.vitocassisi.lux.plugin.search" /> </intent-filter> </receiver> <service android:name=".[B]MY_PLUGIN[/B]" android:exported="true" > <intent-filter> <action android:name="[B]YOUR_PACKAGE_NAME_HERE[/B]" /> </intent-filter> </service>
Be sure to replace YOUR_PACKAGE_NAME_HERE with the name of your plug-in's package, and MY_PLUGIN with your extended PassiveDisplay class.
And that's it! Now you're ready to test!
Enabling Plug-In support within Lux
To enable plug-in support, you must check 'Enable plug-in support' in the Advanced section of Lux settings. Enabling this option forfeits all responsibility of mine for any issues caused while using Lux. Plug-in's can cause very real damage to your device if they're written incorrectly - don't use plug-ins from sources you don't trust!
Testing your plug-in
Testing is critical for creating a good plug-in. You are dealing directly with system files, and can easily cause damage if you do not know what you're doing.
DO NOT RELEASE A PLUG-IN WITHOUT TESTING IT ON THE TARGET DEVICE FIRST!
Ensure that the following work with your plug-in installed:
- Astronomer Mode
- Night Mode
- General brightness adjustment
- Lux readings functional
BE METICULOUS WITH YOUR IMPLEMENTATION OF isSupportedDevice()!
Modifying system files on the wrong model/kernel may cause irreversible issues!

- Misc. fixes11Hey everyone. Sorry to hear that people are having issues with the paid version. I'm working on hotfixes at the moment. A lot of these bugs don't appear on my test devices, which is why regressions happen seemingly randomly. I'm working hard on finding a reliable way to reproduce and test these issues to prevent this happening again.9Apologies to everyone for not being around lately. I've been answering support via email.
A new release is rolling out on the market to 5% of users. Please use the 'Send Feedback' button in Lux preferences if you experience issues. Also, feel free to email me with any questions or concerns. - Update to 1.51 released to Play Store!
