"To put it simply, Lux kicks the pants off of Android’s stock brightness manager, and it’s worth every cent." - Lifehacker

"Lux is a third-party app that allows you to easily calibrate your phone’s brightness sensor, saving you battery power and reducing eye strain if your phone is normally too bright in dark rooms." - HowToGeek

Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If 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 is also able to adjust the screen temperature of your display automatically to make it appropriate for night usage. At sunset, you can have Lux automatically warm your display and switch to your Night profile. If you're an astronomer, you can enable astronomer mode to cut out harsh white light. If you have a root enabled phone, you may even be able to apply these enhancements at a low level with Lux's plug-in system.

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 within a week of purchase via e-mail - no questions asked.

    Awesome. Now brightness is within my reach. If your mobile is a mordern smartphone with superr high brightness, even at the least brightness you can toggle, while using in the dark, this app is for you. It basically lowers the brightness below the lowest level, doesn't harm device or anything. Helps to go easy on eyes in dark environment. Simple app, does what it says, no ads so far, love it !!!

  2. Quinten Mandema-avatar

    Quinten Mandema


    Very very good app. It's easy to use and prevents you from getting sore eyes when you set your alarm in the middle of night. I only have had 1 issue until now. The app sometimes likes to edit it's own settings for no good reason. This can of course be my fault but it has happened too often to be accidental.

  3. Mustafa Alsoffi-avatar

    Mustafa Alsoffi


    Well, it brightnes, but I have to manually dim the screen(dynamic mode, which should detect the significant decrease of light). It fails to deliver its main promise so I don't think the premium version worth investing in.

  4. Andy Kaylie-avatar

    Andy Kaylie


    Abandonware? I used this app for a long time. Just "inherited" a One plus 6t running android 10 and it's auto brightness doesn't work. Downloaded old trusty lux to find its impossible to even get it installed as it looks for a setting change that no longer exists. Not surprising considering the last update was in 2015.

  5. tva il-avatar

    tva il


    Free app does nothing to help dark screens (particularly movie streaming or on players where pictures render too dark). Apparently you must buy the full version of this app in order to achieve anything worthwhile. What a waste of data $ and time.

  6. T Striker Animations-avatar

    This app is amazing for when I want to lower my brightness beyond it's normal limit. Great for privacy and personal use.

  7. Nomen Prenomen-avatar

    Nomen Prenomen


    Brightness set on Lux to 100% is still too dark. Can't make it brighter. It works on android 9 after you allow data access permission. It hard to find but in my RemiNote5 it is located in: settings/passwords & security/privacy/special app access/usage access.

  8. Rick W.-avatar

    Rick W.


    It works well for what it's supposed to do, but it causes a big problem. Other apps produce pop ups on my screen, but those pop-ups are not able to detect my touch when Lux is running. So, for example, a pop-up shows up on my screen that asks me yes or no, and I can tap it all I want and it doesn't detect my touch. It's a shame because I really like what Lux does, but it interferes with too many other things.

  9. Stephan de Witte-avatar

    Stephan de Witte


    Love the brightness limits, but app goes to sleep all the time. Samsung wants to increase brightness to 100% way too soon and won't adopt a lower setting. Lux helps by maximizing to 90%. However, despite the active notification, the app goes to 'sleeping' after each screen lock, thus it won't change brightness automatically anymore. Especially annoying when it ass set to 10%, then you go outside, and can't read the wake button, or when you come home and see a 90% bright screen in a dark room...

  10. Teri Elmore-avatar

    Teri Elmore


    I first used this app years ago & now I keep coming back to it every time I use a phone that doesn't handle brightness quite how I want. This app is way better than the built-in auto brightness on most phones even with minimal configuration. Unfortunately it doesn't seem to work on Android 10, it just crashes immediately. Hopefully it will get an update.

  11. Grant Finnegan-avatar

    Grant Finnegan


    Great! Am absolute must for late night phone usage. Just a couple very minor bugs, and it blocks chrome permissions dialogs through no fault of the creators, so you'll need to disable it temporally occasionally

  12. Rudolf Enberg-avatar

    Rudolf Enberg


    Needlessly complicated I think. There's a custom notification with six buttons, and tapping it actually brings up another UI with about ten. I think some restraint is needed. My life doesn't revolve around screen brightness. I only want to set this up once and forget it even exists. Because Android's Adaptive Brightness is so useless on Nokia 8.

  13. Johannes Toppe-avatar

    Johannes Toppe


    Forgot about the app being installed, was causing problems on S8 android Pie. Every time I unlocked the phone, the brightness would go all the way up to max for no reason, and adaptive brightness would turn off. It was so annoying, and I thought something was wring with my phone. it was this way for several weeks until i went thru my phone and discovered it was this app that was making the problems. uninstalled it and i have no problems now. caution against any s8 users....

  14. Ethan Anderson-avatar

    Ethan Anderson


    I love the app and it really helps when watching shows/movies or YouTube in bed or in the dark. My only complaint is that I can't disable it during the day and how it always has to be on my notification bar. The only way I can use it at night and have it off during the day is if I delete and reinstall Everytime (which is what I've been doing which gets really annoying). Otherwise great app!

  15. Wormwalll-avatar



    An amazing app for when the screen is too light or dark

  16. Graham Helliwell-avatar

    Graham Helliwell


    Looks generally good, but is implemented with a filter that doesn't cover the notification bar and back buttons. Would be better if it controlled the backlight like the experimental twilight feature does. In case it's helpful, my use case is just to make my phone darker when using in pitch black during sleep hours so as not to disturb my partner with a bright light.

  17. Christine Hottinger-avatar

    Christine Hottinger


    Stopped working in the middle of the night, and now won't go subzero. From other reviews, it seems this is related to the Android update, but still. I relied heavily on this app to make my phone a reasonable degree of bright. I had it on manual, and would turn it wayyy below even what it wanted, which was always below what Android wanted. Now, it basically won't go subzero, so goodbye sleep.

  18. Jackson Banks-avatar

    Jackson Banks


    I would give 5 stars except I can't tap android allow access or permission tabs when this is installed. Please fix this issue. I gave to uninstall and reinstall whenever I have to use allow permission pop ups because this is the best screen brightness adjuster I have found so far. Maybe disable and enable buttons would be a good iidea

  19. MR RIKKLES-avatar



    This app is EXTREMELY HYPER-SENSITIVE. Every single adjustment in light in the room, no matter how miniscule, causes this app to adjust the screen brightness, and for me, it was doing this EVERY FEW SECONDS OR SO. I'll gladly stick to Samsung's bog-standard, at least it doesn't wildly fly out of its own ass whenever it feels it needs to have a seizure.

  20. O L-avatar

    O L


    Very useful and effective but PLEASE stop the screen flashing FULL BRIGHTNESS the moment Lux is enabled, doing this in a darkened room is blinding. And please stop reverting androids default brightness setting to auto once lux is disabled. Additionally, please include screen overlays like Messenger to have the light filter as well, everytime a message is opened in overlay, the filter doesn't cover it

  21. Bloody Mobile-avatar

    Bloody Mobile


    So I've installed this because my J6 lacks a light sensor, for whatever reason Samsung thinks that's a better saving than NOT adding the front flash, and it tells me I don't have a light sensor, big news, and says it'll use the camera instead. Except that it doesn't. Seems like the free version is limited to NOT using camera which totally breaks the point of installing it.

  22. Jonathan Harmon-avatar

    Jonathan Harmon


    The premise makes sense, it's why I tried it, but execution is terrible. It's nothing more than a screen filter overlayed onto the UI, not actual brightness control of the backlight. As soon as I drag down the notification area I am blinded because I assume screen filtering can't be applied there. Can app developers not have access to the actual backlight anymore? And why all the pervasive app permissions if it just needs the light sensor to do its thing?

  23. Megswede B-avatar

    I have an LG K20 PLUS Android phone. All of a sudden, upon watching Netflix, it became so dark, I couldn't see hardly anything on the screen. I tried adjusting every display setting on my phone to no avail. After research, I tried this app and it solved the problem! Perfect solution.

  24. gabriela-avatar



    When I tested the app it looks pretty good. Really. But when I tried to use it a second time, the message “Unfortunately, Lux Lite has stopped” appeared. I don't know why this happened, but now I can't use the app. Please fix it. Note: I tried to uninstall and install again, but the problem remains the same.

    whenever I swiped down the notifications bar at the top of phone screen the dim light on screen isn't on the top the area that the notifications bar takes up while being slid down is bright bright bright and on my phone the lowest brightness that this phone give hurts my eyes badly so whenever I need swip down my eyes hurt cause the light. I used this app for a while and on alot of phones this the 1st time this happed to me my phone is Alcatel 7 I don't know if maybe phone type is the reason?

  27. Gregglo Kleene-avatar

    Gregglo Kleene


    At first, I liked this app as it definitely increased the brightness! However, this app automatically darkens the screen where it's almost impossible to see the screen to increase the brightness! I set it on manual as the other settings seemed to adjust the brightness level even more sporatically. Also, the adjustment bar is very hard to select a specific percentage since it keeps jumping around.

  28. Kazuma Kariama-avatar

    My experience with this app goes back to 5 months ago when i struggled with the brightness in pitch black environments. It was too bright and this app fixed that! I switched to Android 10 and it stopped working. I figured out how to get it to work. Go to Apps/Special Access/Usage Data Access/Lux Lite From there, enable and it works!

  29. Jacinta Morrison-avatar

    Jacinta Morrison


    Great app, I've used it for years, always been very happy with it! But the android 8.1 update messed it up. Now the top bar and the drop down menu are lit up bright, even when the rest of the screen is dimmed. I hope this can be fixed soon.

  30. Ronel Vincent Ching-avatar

    Ronel Vincent Ching


    It does not work properly anymore on my Samsung J7 (2016), Android 8.1.0, because other apps that overlay other apps like the chat heads of Messenger don't get affected by the brightness change, and the Notification Bar does sometimes work, sometimes doesn't.

  31. Elijah Lee-avatar

    Elijah Lee


    Need an app to help my Redmi 7a to increase the backscreen light intensity during outdoors at bright sunlight as the screen is too dim. Downloaded this app to try but it won't work. It keeps showing to approve some sleep mode thingy but it's not in my phone's setting. I hope you can fix the app so it will work on everyone's phone.

  32. Robert Gruszka-avatar

    Robert Gruszka


    Very unreliable. Set as default with the only change: periodicaly update every 3s. Sometimes updates the lux value and screen brightness evey 3s . Sometimes after random time 3-40s. Sometimes never updates the value and never change the brightness. Even I dont change settings. Cant trust. Can buy full version

    Something is wrong. The app was working great and I loved it, but suddenly sub-zero lighting just stopped working and I don't know why. Edit: Reset the app, and now it's working fine. Must've been a glitch or a setting I put in by accident. Now it's working great!

  35. J C-avatar

    There is no reason this app should ask for the permissions it's asking for. What do you need location, calls, and other permissions for? Oh that's right, data collection. There is no reason you'd need access to anything except the sensor on the front of the phone.

  36. elfmirfkin-avatar



    I like that I can make the screen brightness ultra dim. I recently had to uninstall and reinstall because it stopped working. other than that, no issues.

    love this app even though the developer has gone quiet. you have to enable "display over other apps" and "modify system settings" yourself in android 9 or 10 because the app permissions popup doesn't point anywhere anymore. then the app still works

    Doesn't actually lower brightness. Need hardware brightness to go below minimum. Sub zero mode just makes things darker but the LEDs stay just as bright so it puts the same strain on your eyes.

    Go to launch app and presents message to go to settings and allow permissions. Click the settings, which should take me to the page, but does not. I go to settings in my phone, enable all settings and still will not launch.

    Doesn't work... Tried installing on a new galaxy s10e to lower the brightness below android's zero point. Sadly it crashes after trying to direct me to settings. Guessing it doesn't like android 9.0.
