Having a problem with lux on my HTC one m8.

My preferred adjustment setting (on wake) doesn't work. When set to adjust on wake the app doesn't pick up any light sensor readings. Dynamically and ascending adjustments work fine. Also in debug the light sensor appears to be working fine. When set to on wake it just shows the last sensor reading from debug and never updates.

Also should mention that I have no issue on sense Roms or gpe Roms, only on aosp.

Any idea what the problem is?

So I'm not too impressed right now. I've been using Lux for a long time now, and it has been an awesome app. Saved me tons of battery life and makes the screen brightness much more convienient.

Now it just sucks, not sure why or what happened, but here's the deal:

Samsung Note 3, running Jedi Elite V2 (based on 4.2.2 Kitkat) with the Lean Kernel. Latest version of Lux. Stock brightness auto adjust is off, stock brightness slider is set to minimum (though I've tried it with it set higher and max too with no helpful effect).

What happens is, when the Lux panel is not in the foreground, the brightness settings do not get controlled very well. I have tried Dynamic and periodic (3, 5, and 7 seconds for the latter) and both do similar stuff. When I pull the notification bar down and open lux, or open it from the app tray, as soon as it is open the brightness falls dramatically and goes to where it should be. Sometimes it stays there, other times it bounces right back up to max or near max. If it isn't in the foreground, and is just running in the background, it rarely goes below 90%, even if I'm in the dark. When I open lux up, it immediately drops to 5-10% (in near dark, depending on ambient light). I back out of lux and sometimes it stays for a few minutes, other times it jumps right back up.

Makes for HORRIBLE battery life.

I've tried the sensor poll time at slowest, slow, medium, and I've tried different minimum brightness settings.

Any ideas? this really sucks, because this app used to work great for me.

Dumb question...did you check to see that your light sensor is working properly? I believe there is a setting in Lux that lets you check that.

Have you tried adjusting on Wakeup just to see if Lux is responsive and behaving like it should?

I also have a Note 3 running a custom ROM and Lux seems to be working for me though it does have issues with S view (see my previous post)

Hi, I state that my English is the result of the translator.
I installed it on a mini Galaxy S3 cyanogen11 after I installed Lux Auto Brightness but I noticed that when it is running I can not press the "Allow" popup that both Superuser of Supersu (later installed to test). If lux is terminated buttons are clickable. Can you tell me if it is a known issue and there is a solution? thanks

As mentioned previously, it would be nice to get better integration with S View on the Note 3. I have the Note 3 with the official Samsung S View cover. Here's whats happening with me:

I have Lux set up to adjust the brightness on wakeup.

If I turn on the screen with the S cover closed, Lux will dim the screen according to my settings. Because the cover is closed Lux thinks I am in a very dark room so the S View screen is dimmed too low. It would be nice to somehow have Lux not adjust the screen when the S View cover is closed.

Accordingly, if I open the cover after first turning on the screen with the S View cover closed, the screen remains dim which is makes sense given I have Lux set up to only adjust the brightness at wakeup.

Ideally, Lux can be set to not adjust the screen brightness if the S View cover is closed. Maybe just use a fixed value. And if the screen is turned on when the S View cover is closed with Lux set up to only adjust on wakeup, Lux should adjust the brightness when the cover is open.

I know I can set Lux to adjust the brightness dynamically but this is the only situation where I would use this instead of adjust on wakeup.

Anyway, just an idea...

Check post #1574, like 2 posts above yours: use the "Ignore 0 lux" setting. It'll maintain whatever brightness it was at prior to closing the cover.

OK, that answer was on the previous page of posts: Install 1.95, here's the copy I kept on my Dropbox. No clue what's wrong with it, beyond the fact it's broken and that it's supposedly being fixed in betas or something.

Samsung Galaxy S5, non rooted. Lux Pro 1.99.992.
I use the app with periodic mode.
In low light conditions I'm quite happy with Lux pro but in light conditions I don't understand how it works.
Lux lets me configure brightness as a function of Lux value.
My understanding is that Lux value is a function of data from light sensor.
With some testing I found the following:
Sensor reading 0..ca.5000: Lux value = Sensor value
Sensor reading ca. 5000..>100000: Lux value = 5008 constant!!!

Sensor values above 5000 are normal values in daylight. Sensor values ca. > 100000 are normal values in bright sun light .
But I can't make use of this information because Lux app limits the Lux value to 5008.

Anybody else with similar observations?

Lux and Tasker

Having problem where I trying to get Lux to turn on Display if the phone is ringing. I manage to set the Event (Phone Ringing) but when I select the Lux Plugin, once I have made my configurations then back out I get the Error toast: Error no plugin configuration data. Have tried over and over to find a way round this to no avail. Any help?

Are you trying to load custom settings just while the phone is ringing (what specifically are you trying to customize)? Which version of Lux do you have? I tested it with 1.95.

The latest update to Lux bring any issues to anyone else? Seems Lux just doesn't want to work correctly on my G3 now .

I've wiped out my profiles, uninstalled and reinstalled and nothing.. I'll have to try and earlier release this morning at work and see what's up

I have a problem with LUX and cm11 for S3 Mini:
the inability to press "allow" when prompted me to superuser/supersu root access by applications.
I am forced to end the dashboard of Lux.
Are there solutions? Thanks!

I've had issues after installing 1.99.993. Lux would give me readings of 0 lux no matter what light. I checked ignore 0 lux readings but it still functioned the same, no change in behavior. Always getting 0 lux readings.

I restored a backup of an older version so I can keep using lux.

Does anyone else have similar issues? I guess I'll have to wait for the next update and how it works.

Galaxy S4 w AOSP ROM 4.4.3.

You really need to be more specific if you expect any help. Just saying that you're having "issues" and that it "doesn't work" is very cryptic and useless to anyone trying to help you. Please be very specific: what exactly doesn't work? What are these "issues"?

Sorry my friend I forgot I had even posted that. I was half asleep and In a pissy mood. I usually know better.

It seemed after the latest Lux update that my Auto Brightness was just all over the place, not behaving at all, one minute bright next way to dark, not following my profile at all.

Im a long time lux user so I somewhat know the tricks to these things and to be honest with you I uninstalled lux a couple of times and installed again, And now it seems to be working once again.

Im on a G3 stock rooted ROM so I either thought it was a Lux bug or maybe my phones sensors even... At this point it doesn't matter. Lux is working just like it always has for me, very well. Must have just been something odd on my end.

    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.
