"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.

by W####:

This app is great, I used to loath using a phone in bed but the brightness can be lowered so much that it doesn't strain my eyes at all. For how useful it is it has been extremely annoying on a few occasions where I find that an app I love has changed a menu to something that is completely valid, but it completely breaks because of this app. Also you can't install apks without disabling this app.

C70%
by C####:

It randomly stops working. To get it to work again I must uninstall, reinstall and restore previously saved settings. It's an amazing app but this is a significant issue. Good thing I waited before spending money for the paid version.

C70%
by C####:

It slows the phone terribly due to constantly restarting thus freezing my phone. Please fix it! And it doesn't turn off ..it just comes back on by itself when you turn it off. It's a good app but I'd be happy if it had those upgrades I mentioned above.

C70%
by C####:

Not sure why people are giving it five stars. This app still crashes once you have to turn it off for a second to give permissions to another app and won't reopen. I've had to delete and download more times than I can count.

C70%
by C####:

Day one this app stopped working. I was hopeful about this app too. Plus I had to go into settings and change the Draw over setting when I was doing something in another app. Not for me.

C70%
by C####:

I know it night be to do with andriod. But this is just annoying. I can't store pictures from other app as long as I am using lux(give permission to over lay)

C70%
by C####:

It seems to have a problem with the newest software update for Android phones, Android 6. Screen overlay permission blah blah, solution: turn off lux during the day in the app's settings under advanced settings. Or hit the "sleep" button for the app, all your apps should work like normal.

C70%
by C####:

Does pretty much what it claims, quite well. The only problem I've faced is that it blocks out buttons at the corner of the screen during installation of applications. Have to disable the app before buttons becomes clickable.

C70%
by C####:

Only a few complaints, but this is the best app for customized brightness adjustment I've tried and I have tried many. It's a bit of a pain to enable and disable and some apps make it glitchy, but otherwise it's quite a worthwhile application.

W70%
by W####:

Great idea, but it killed my battery. Would discharge battery even when screen was off. Also interfered with other apps. Had to turn off lux lite to start another app, then turn lux lite back on. Actual response to light change was smooth and fast, but too many other problems.

C70%
by C####:

It's mandatory to pause Lux Auto Brightness whenever I am installing apps from sources other than Play Store or else the 'Install' option freezes and hence, it's a ★ ★ ★ from me until this issue is fixed. However, I must agree that I adore the option that allows me to set the minimum screen brightness and I also appreciate the option to reduce the screen brightness manually beyond default android zero level and even up to -100% which makes reading in a dark room really easy on the eyes.

Y70%
by Y####:

My Nexus 6 brightness at its lowest setting was too bright, this app allowed me to reduce brightness into the negative space and now at night it's not blinding. My only gripe is I wish that the notification bar was a notification icon for Android 7, tap that to open the app and adjust from there to keep my task bar clean.

S70%
by S####:

So honestly this app is wonderful and I love it. But as an android user, I keep running into overlay problems with Lux. I gave Lux the overlay permission, which is fine by me. But whenever I install a new app that asks permission for various things, I always end up uninstalling Lux, giving the other app it's permissions, and reinstalling Lux. It is really not a big deal, but considering I have done this possibly 20 times already I would appreciate any feedback or help!

Thanks, my Samsung Galaxy Tab 4 brightness adjustment doesn't work and I curse it a night. I just installed this and it did the trick. I'll post back if anything goes wrong. So far very nice, should have installed this long ago. March 7 2016. Update; It's 3am and I'm really appreciating this new app

C70%
by C####:

Very effective app! I use it on my LG G2 (VS980) and Samsung Galaxy Tab S . I have however found that this app interferes with several other apps by blocking button selection. When I encounter this interference I have to disable Lux in-order to use the infringed app.

D70%
by D####:

It works well sometimes, but other times it doesn't automatically adjust the brightness, its like it went to, sleep, even though its still active. Also it's tedious to turn off lux every time an app says it needs screen overlay turned off. I even suspect it's the Cause of temporary screen burn in on my LG g5, where icons like battery or Wi-Fi are still visible for hours later. I would like to, know the benefits of the paid version???

D70%
by D####:

Works perfectly! There are a lot of extra features that I never expected to see! This is perfect for watching videos in bed and not disturbing the wife. I had an issue where after an update the app caused my phone to lag horribly....but after uninstalling the app..restarting the phone and re-installing...all is well!

Z70%
by Z####:

Great app, even the free version works really well. Reluctant to upgrade as the draw over other app seems to interfere with other apps. I understand this was done so it would work with marshmallow but is there any plans to change this so it doesnt cause a problem?

C70%
by C####:

I've been using this app for less than 24 hours now, and already I don't know how I ever got along without it! Setup doesn't take long at all, and "teaching" the app your preferred brightness settings along the way is easy and quick. I wish I had found this app ages ago!

G70%
by G####:

Whenever I need to change any Android security settings, I have to disable this app. Overlay detected is the problem. The annoying part is, that I don't use subzero brightness at all. Disabling this feature might solve the problem, but the option is missing. Otherwise perfect.

N70%
by N####:

It really does work nicely. However, the longer you use it, the more it'll slow down your phone's wake phase (meaning dealing with a frozen lock screen for up to 30sec). Occasionally does get stuck in sleep mode. I would like to buy it, but am unsure if the paid version exhibits the same problems...

C70%
by C####:

I'm a night owl and use my phone often during the night. Since I had installed this app I've just been using it frequently. However, there still remains one issue: the 'screen overlay detected' dialog. And until this issue is solved I'll only give it 4/5 stars.

C70%
by C####:

... It's conflicting with other apps.. Screen overlay issue..I've read somewhere if you click to alternative screen in advance settings it fixes a problem, and this worked for me.. Nexus 6p..I'm surprised you guys haven't posted a solution!

E70%
by E####:

This app is just what I need! However I also have the same problems with screen overlays. But what's most annoying is that all screenshots are darker if you don't turn off the app when you take them.

C70%
by C####:

Is this supposed to save battery life? I installed this late last night. I had the bedroom lights off. It turns my brightness to 4% and I can hardly see anything. Garbage app.

C70%
by C####:

Excellent app! My Droid Mini does a terrible job of auto-adjusting the screen brightness and makes the battery drain too fast. After I installed this app, the battery life is much improved. It's free, setup was a breeze, it does a great job and stays out of the way. What more could I ask?

C70%
by C####:

Great app but it causes a lot of problems on Marshmallow because of screen overlay. The advanced option of alternative screen overlay makes no difference. Many apps like Whatsapp refuse to set certain permissions like acces to microfone. I had to de-install to be able to get certain apps to work properly.....

Z70%
by Z####:

I was strongly considering buying this app until I discovered that the app goes into sleep mode whenever I'm in a call and does not dynamicaly adjust my screen brightness. I pulled my phone away from my head and couldn't see the screen. That makes this whole app useless to me.

C70%
by C####:

I like this program but i cannot use my phone with it installed. It lags out my messages as it auto updates the brightness. When i turn on my phone there is a 1 second delay before i see my screen. This is on a samaung galaxy s4. Fix the delay and ill come back.

N70%
by N####:

Works great, but it's overlay doesn't play nice with Android and certain apps, so I find myself having to disable and enable it far too often. I'd give five stars if it wasn't such a PITA.

G70%
by G####:

Works great, but like others have said, it behaves like malware in that it just won't turn off. I turn it off with the power icon in the notification screen, and it turns itself back on the next time I wake my phone. You can't close the app completely either by swiping it away like most apps. I have to go into the system application manager to force kill it and even then sometimes it restarts itself.

N70%
by N####:

At android 6.0, it stops frequently unless draw on other apps is turned on. Yet, if is turned on, lots of buttons will be influenced. Please fix it. Thanks!

N70%
by N####:

This would be 5 stars if it was possible to simply disable the app. A lot of the time during the day I don't need the brightness to be dynamically adjusted, was turning the app off via the power button often times restarts soon after or doesn't turn off at all.

N70%
by N####:

After having this installed for a few months, the brightness would snap back to where it was before I set it down. I'd be in my dark room and all of the sudden the brightness would increase like crazy. Used to be 5/5.

A70%
by A####:

It really keeps my eyes free from strains, irritations etc especially in the dark .And it's comfortable no matter whether it's a day or night time.

N70%
by N####:

Got lux last night since the brightness on lollipop doesn't go down nearly far enough and I love it but today i noticed it makes the keyboard have a terrible lag which is very frustrating. If that's taken care of its 5 stars.

N70%
by N####:

It keeps turning back on when I switch it off during the day. I have to keep manually switching it off, or disable it to prevent it from turning back on, which is annoying. Please fix and I'll rate the app 5 stars. Nexus 5 running on Marshmallow.

N70%
by N####:

It gets so low that the screen looks almost off which is perfect for night time reading. Bright enough for out door use.

R70%
by R####:

In general, I really like this app. It allows me to set up 3 lighting settings: day, night, and car. It also allows my phone to get much dimmer than it is naturally capable of. However, there are a couple downsides. The dynamic lighting goes crazy in dim lighting; very annoying. Also, this app seems to interfere with other apps privileges.

P70%
by P####:

The notification control lags severely on the lockscreen, causing an annoying delay while locking/unlocking the phone. One of the key gripes,otherwise I was on my way to pro! Functionality is neat otherwise.
