The original custom auto brightness solution for Android.

Please note that this is the free version of Lux. For the full version please click the following link. Purchasing the full version supports further development of Lux, and is truly appreciated.

"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.

    Does a great job of lowering brightness to below levels that android can do by itself. Great for night time or dark rooms to prevent bright display shock.

    the default auto-brightness is just too aggressive for me and the phone battery. This app helps so much!

    My moto x is too bright even on its lowest setting. With lux I can go into the negatives tho! Save battery, pixels, and your own eyes! I don't usually go above 0% at all

    On Note 2 I would end a call and my screen would go into astronomy mode-turned screen a fog of red. Uninstall app
