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 within a week of purchase via e-mail - no questions asked.
DO NOT request features, report bugs, or ask for assistance in your review. I can't reply to them! Please e-mail me instead.

Awesome app I've emailed the developer about the awful notification icon. It was designed for ICS so it looks good for that. He will look into the design for non ICS droids. Awesome app nevertheless.

Great so far I really like the simple and intuitive way this app works! It's how auto brightness should have been implemented in the first place - adjusting the display relative the ambient light in a smooth way, that can be modified by the user. Highly Recommend!

Great Saves my eyes late at night when everyone else is snoozing! One thing though, could you make the status icon smaller so it fits in better with the rest of the status icons?

Excellent Lots of configuration potential. Needs a lot of tweaking, but very powerful and saves a noticeable amount of battery.

A saver of samsung exhibit The new version fixes the luma bug on exhibit phone which does not have a light sensor and thus saves the autobrightness feature there. Not to mention that trained interpolation is how autobrightness should have been implemented to begin with. One of the rare ocasions i truly enjoyed the intelligence of a phone app.

Iffy on Galaxy Nexus First you have to switch your brightness to 100% on your Galaxy Nexus. Then have to check the option for Sub-Zero only in the general options. Now you can start teaching Lux how to change your brightness. I found that the automatic adjustment did not work at all for my galaxy nexus. It just didn't change the brightness until I pulled up the Dashboard. I ended setting it up to change the brightness on wake and that seems to work ok. I still wish I could have the program react to the brightness automatically.
