Changelog:

v1.31:
- added smooth button mode support for some HTC One series kernels
- added ability to force buttons on/off as exception

v1.3:
- fixed buttons sometimes staying on when sleeping in root mode
- fixed crash when canceling exception
- added Czech translation
- marked as compatible with Android 2.2
- sample queue is wiped on wakeup for quicker re-adjustment to new light level
- increased reliability of root commands
- experimental more reliable button off on sleep (root modes)


v1.2:
MAJOR CORE CHANGES, CLEAN REINSTALL RECOMMENDED
- reworked sample queue and calculations to allow for intermediate values, resulting in more smoothness in precise mode
- decoupled sample queue and update queue length (update is now performed after every sample if needed)
- above results in lower average latency and allows for longer sample intervals (less CPU usage, more smoothness)
- above also makes larger sample queues viable as means to smoothen out sensor fluctuations
- added ability to apply user min/max as dynamic range for all calculations (compresses CalBrightness into user range instead of capping)
- Lumos will try to use root access to bulletproof itself if you disable ongoing notification icon
- fixed crash after increasing sample queue size
- tweaked the graphs of built-in profiles to better accommodate dynamic range compression
- added backlight fix for HTC One series phones to prevent button flickering (you need to switch the mode manually)
- allowed broader range for sensor sampling rate and sample queue
- showing average latency instead of worst case in settings to get more realistic numbers
- fixed bugs in relative exceptions
- installed app list is now sorted by name
- other minor bugfixes
! your sampling rates, queue size and animation length settings will be reset after update
! new option Compress Dynamic Range will default to ON

For One X+ you need to use root mode to get reliable on/off and stock-based ROMs don't support smooth levels, unfortunatelly.
Maybe AOSP ROMs will add the support, because I doubt it is a hardware limitation but rather driver issue.

New version

New version of Lumos v1.2
is released and will appear on the Play Store shortly.

In the meantime I added a changelog to the second post and it is pretty extensive

Hope you enjoy the update as much as I enjoyed making it!

Sorry Lumos needs 2.3 or better

New version

New version of Lumos v1.3.1 will appear on the Play Store shortly.

It now fully supports smooth button backlight management on some newer One X and X+ custom kernels like EliteKernel and Blade kernel.

Also you can for example set the buttons backlight to be off for your video player using an exception.

Enjoy

The thing is, once the call window appears, no app can change brightness until the call ends (at least on htc). The control is returned to android and there is no workaround i know of. I'll take a second look later in case something changed in 4.2.

If you turn the display on, the sensor sample queue is wiped so the change should be almost immediate. But the call turns it on in your pocket and then returns control to android.

Maybe you could try to add an exception for the phone app and force the display high, but I don't think that will work either.

And thanks for the review
