calm down everyone..
I spoke to the Dev not too too long ago and the app is still being developed though at a much slower pace.
I'm sure something will turn up before or shortly after O is officially released.
To adapt something to work on an android O preview beta is not really a priority I imagine.

I"m OK, no problem.

There supposed to be another Android 0 beta release this month, maybe he'll get it to work with that.

I'm emailed him and he never replied. It's be a good idea to get it to work on the beta, so that it will work on the official release without having to fix it. Hopefully, because I like Lux's options more than the competition.

Lux completely stopped working on Samsung S8

I've been using Lux for several years now and love it. However I just got a Samsung Galaxy S8 and Lux will not adjust the brightness automatically, ever. It stays at 100% all the time. I've uninstalled/reinstalled and added it to the battery saver whitelist, but no-go. Anyone have any suggestions?

Thanks

Problems on One plus 3 in bright light

Hi,

I've been using the paid app for years across devices. I haven't found anything to replace this app. On the OP3, however, I have two issues, one a show stopper and I had to uninstall it. Annoyingly, Lux makes notifications unresponsive, it takes a few seconds to be able to interact with notifications quite often. The really bad behaviour though is how it sometimes does not react in bright light, meaning I cannot see the screen at all for quite a while. In addition, the screen does not come on when receiving phone calls. The latter I cannot pin on lux definitively, I will have to see how I go now I've removed lux.

It's a shame there's not been an update on over a year, there was no update for N, let alone O. I do hope the dev comes back to this excellent app and fixes bugs. I will miss the subzero brightness, I'm finding the screen too bright as I write this already.

Cheers
Martin

I've been using Lux forever, but I've been messing with some of the advanced options lately. I'm running 7.1.2 on a Pixel. When I switch on the KCAL support, it works but I lose the ability to use any sub-zero settings in Lux. Is that normal, or did I miss a setting somewhere?

Sleeping itself.

Recently my Lux Lite goes to "sleeping" automatically after few minutes, and everytime i wake up the phone i need to manually turn off the "sleeping" before lux will update screen brightness. Then after while "sleeping" gets turned on by itself again. Is this by design? It wasn't behaving like this before.

I've done a search and it seems that last time someone reported this problem was 2015...

Well the last time Lux Lite was updated was in 2015 - No idea if your issue is because of continued development in other areas of your device / rom or if you're having an issue without any other changes?

Does anyone have a problem that light sensor keeps jumping back and forwards between 0 and 1 lux in difficult dim lighting conditions? Can I change settings somehow to alter this?

No, lux is better than the stock app.
Don't know what stock app you are referring to - But I disagree - Lux uses an overlay which is a pita - It hasn't been updated in over a year and Stock UI as well as Custom Roms are far more developed... Anyway - That's my opinion and you're free to have yours ?

On my my OnePlus 5,in a dimly lit room, it reduces brightness to almost 0, that is no good, as I cannot see as well as I would like. And I will not change to custom rom just because of screen brightness. Lux works the best right now.

Edit: it dims brightness to about 3% in 0 lux, So i still have turn it off to get less brightness in bed.

just use sub zero..
you can even link a profile so it does that automatically after sundown
Lux is hands down the best screen brightness app, even if it hasn't been updated in over a year.
It still works better than anything else out there, especially if you combine it with cf lumen bij chainfire ;)

I was talking about stock adaptive brightness..

I like this app, and I still use the paid version (I decided to try the built in adaptive brightness on my pixel 2 when i got it, and lasted about 5 minutes before reinstalling Lux)

I just wish we could get an update for a couple of things:
- A grey on white option for the notification so it blends in with the rest on newer Android versions
- Notification channels

I'd even be willing to pay for the app again for an update.

    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.

    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.
