Overview:
The original custom auto brightness solution for Android.

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 provides the option to automatically adjust the backlight at fixed intervals (periodic mode), when a change in environment is detected (dynamic mode), or only 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!

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.
