I have an issue on my Nexus 7 (2012) running 4.4.4 stock. Whenever I enable night mode I start to experience noticeable lag in all animations, especially in the app drawer. The lag is absent from the second I disable night mode.

Is this a known issue, and if so, is there a fix?

Yes, by me. I mailed the developer and he provided me with this solution.
After further investigation, this solution does not work — CF.Lumen is being loaded in memory on every boot, and it stays there.

Or use Lux version 1.99.9991. Last version with working cf.lumen without having to pay for pro version.

I have purchased CF.Lumen from day 1, even though the app was always disabled on my phone. What I want is simply be able to disable this app once again, so it doesn't eat my phone's RAM and battery while I'm not even able to use the app.

Great app, I will buy the full version as soon as I can.
Have you considered creating a refresh button widget? It's particularly difficult to try and tap the refresh button on the notification bar, particularly on devices with a small screen.

Also, is it normal for the light sensor to measue 0lx even in a room with dim light?

To say that cf.lumen uses much battery up is ridiculous, because it is minimal. Plus as stated often throughout the years, because a program is in RAM does not mean there is much battery usage.

I have both lux and cf.lumen running on my phone, and my battery life is not noticeably affected in the least. Battery stats show cf.lumen using up 1 mAh in the past 18 hours and my screen has been on for 2.5 hours.

If you're so concerned, uninstall it. Or try Greenify, or freeze it with titanium backup

Please read my comments more carefully before calling them ridiculous. I have never stated CF.Lumen used much battery or RAM, I just said it did and that I don't like constantly running an app which I can't even use just so that the other app can verify that I have purchased it. Now that is ridiculous from my point of view, just like the "solutions" you suggested, thanks.

Imagine every app you purchased would require another app constantly running in the background, unusable, just to verify the purchase. Get the picture?

I'm not here to discuss opinions in PM, I would much rather have this issue fixed, or proper CF.Lumen support added (so that I can benefit from both apps, since I'm forced to run them both).

You are "forced" to run them both? Odd, no one has ever forced me to do anything to my phone... If you don't like it... Don't use it...

Common sense isn't all that common

Really - I used to run both CF Lumen & Lux - But I didn't find Lumen useful for me - I've been running Lux on it's own - And I'm happy with the results.

It helps when you want the soft keys to go below zero value.. That's what I use it for..

I use app ops to prevent CF Lumen from starting at boot. It contains an option to prevent auto starts

What app are you using to detect CF Lumen is running?

Afternoon guys, having a minor problem and I'm curious if it's just me or wide spread?

Every time my screen dims as a warning that the screen is about to switch off, Lux seems to lose control of the brightness, so even if I keep the screen alive, it will stay dimmed out until I open lux again from the dropdown menu.

This behaviour is only apparent whilst CF Lumen is selected as a plugin

Anyone have a fix?

    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.

    ★FEATURES★
    ■ Custom auto brightness.
    ■ Sub-zero brightness to make reading in the dark significantly less irritating.
    ■ Battery efficient
    ■ Handy brightness widget
    ■ Option to use the camera to read in ambient light.
    ■ Power-user settings such as choice of interpolation, sensor debugging, and linked sample editing.
    ■ Backup to SD.
    ■ 'Ascending' auto mode for phones with inaccurate light sensors.
    ■ Gradual fade for backlight adjustments.
    ■ Astronomer mode adds a red filter to the screen to preserve the eyesight of stargazers.
    ■ Jitter control to prevent constant small changes to the backlight.
    ■ Automatic night mode, to change the colour temperature of the display for comfortable night time viewing.
    ■ Add app specific exceptions via sleep mode
    ■ No ads, or other nuisances.
    ■ Tasker and Locale support!
    Note: Please disable other brightness apps before using Lux. The author is not liable for any issues caused when using this app.

    COARSE LOCATION: Required to automatically calculate sunrise/sunset times.
    IN APP BILLING: Required for purchasing future device specific root only plug-ins, to enhance functionality.    ​

    Lux Low-Level Plug-ins

    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!

    Hey 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.
